Townson Happy New Year (TELECOM Digest Editor) Directory to Telecom Archives (TELECOM Digest Editor) ---------------------------------------------------------------------- Date: Mon, 3 Jan 1994 23:05:17 -0600 From: TELECOM Moderator Subject: Happy New Year Happy new year to all readers, and welcome to another volume of TELECOM Digest. We begin volume 14 with this issue. With this issue of the Digest is a copy of the index to the Telecom Archives to bring you up to date on the several hundred files at your disposal there which include all the past issues of the Digest since its beginning in 1981. One new thing you will notice about the Archives is that a sub-directory has been set aside for participants in the unmoderated TELECOM-TECH mailing list maintained by former Digest participant John Higdon. Mr. Higdon has been given a method by which copies of his journal can be automatically forwarded to the archives where back issues can be fetched by interested parties. At the present time, there is very little in this area of the archives, but no doubt it will have additional files whenever TELECOM-TECH is published, should they wish to make their journal available for all archives users. I'd like to point out also that the generous financial assistance sent to the Digest by many readers during the past year has been the main reason I have been able to continue publication of this journal, and I hope those of you who see fit to contribute financially from time to time will continue to do so during 1994, although of course there is no obligation whatsoever on your part. So throughout 1994, I hope you will enjoy the Digest and benefit from the collective wisdom of our reader/writer/participants. That of course means you as well ... feel free to write and comment anytime. The volume of mail is such that only a small sample can be used, but I try to print as wide and diverse a range of material as possible, and your mail makes it possible. Patrick Townson TELECOM Digest Editor ------------------------------ From: TELECOM Digest Editor Subject: Directory to Telecom-Archives Date: Tue, 4 Jan 94 0:45:27 EST The Telecom Archives is a repository of information about telecom topics and a collection of the back issues of this Digest. It is available using anonymous ftp lcs.mit.edu, and also by using the Telecom Archives Email Information Service. Attached here is the most recent directory to the files in the archives, as of this date. The various areas of interest (broken down into sub-directories) are listed first, then below that, the contents of each area. The indices to authors and subjects is in the process of being updated to include the final issues of 1993 and should be totally complete in the next day or two. total 28 -rw-rw-r-- 1 ptownson 0 Jan 3

No criticism here (I assume that 'run(ning) out > of things to invent' was a -in-cheek remark). Without being critical, what's interesting in this string is that your correspondents find it curious and worthy of note, that our ancestors (stupidly) thought their old pace of change was extraordinary. We are being invited to snicker at this quaint and ridiculous idea. Everyone knows, that (by comparison with today) the pace of change of our ancestors was very slow and sedate? That's the sub-text here. But! Every generation thinks that it lives in THE period of most rapid change. Past generations always look slow by comparison because we look at THEIR change from OUR perspective. My guess is that we technologists view the world, distorted in this egoistic way, because our 'present' is always mid-stream in the technological changes that dominate our lives. And, since we egoists are obviously at the centre of the universe, ipso facto, these changes must appear extraordinary and revolutionary to the hoi polloi who don't understand things as well as we do. To our ancestors, these changes would be extraordinary! The distortion comes about because of our viewpoint. The problems and attitudes of the past always appear trivial to us -- because they are SOLVED. Relativity is such a simple and obvious concept -- why did it take an Einstein and X years to work it out? A smart high-school kid today could write a better explanation of relativity than Einstein in a week. And, similarly, we judge the rate of change selectively from our own perspective, having grown up with the 'solved' technologies which caused all the troubles in the past. And our judgement as to what is important is always a perspective from today's vantage point -- but people in the past found other aspects of change more important and difficult to handle -- things that are now trivial to us. This is where Tofler falls down in his "Future Shock" idea. I don't see any evidence that people today don't handle technological change reasonably well and easily. Ten years after Toffler warned us of technology's disruptive effects, Future Shock hasn't appeared in the way that was postulated. Today's technologies certainly aren't any more difficult for us to handle than those that gave 'Future Shock' to past generations (Crystal sets, for instance. Trams and buses for another) Morse-code telegraphy had ten times the impact of satellites. Telex has been a thousand times more important and more revolutionary than electronic mail. Computers and modern communications technologies might be revolutionary to the half-million technologists, but to the five billion users these chips and fibres are just creating marginal improvements on the adequate 'service facilities' they had before. Computers produce a very evolutionary, rather than revolutionary, change to our culture when you compare them to the impact of something like the motor car. My mother was ten before she saw her first motor car, 18 before she saw an aeroplane, but she lived to fly the Concorde and see a man step on the moon. How does this pace of change compare with my life span, when cars, aeroplanes and space travel are reasonably commonplace? And the car I drive now is not really much different to the one I drove 30 years ago. The car has made very little 'revolutionary' impact on my life because I've always had one, and it has always worked at about the same speed and travelled the same miles. So I have reservations about all this philosophical "Future Shock" and "Information Society/Age" stuff -- I think it is tabloid sensationalism under the guise of a pseudo-academic cloak. I see little evidence that the 'perceived' pace of change in the community is faster now than it has been over the last hundred years. It seems to me that 'present' change has always been perceived as 'amazingly fast' -- it's a perspective illusion. If you were to identify the time in recent history where citizens faced most 'Future Shock' then it would have to be the 1890s and early 1900s. This was when Bell invented the telephone; Edison the light bulb and phonograph; photography and the movies became popular; Marconi and De Forrest created radio; and trams, buses, cars, trucks (and later aeroplanes) replaced the horse and carriage and bicycle. All of these technologies had a direct, disruptive and rapid effect on the way (and place) people lived, worked and played. It is hard to think of anything in the last twenty years with one-tenth the impact of the steam-train in the 1800s. In fact, if you stand back and look at the last century of technology with a dispassionate eye, then the computer and fibre revolution has been rather benign for the average citizen. Fibre optics just means better phone quality. And these days the technologists placed considerable emphasis on 'user-friendliness' and on the 'transparency' of most computer applications -- so a large part of the computer's power is directed at making it easy to assimilate, and easy to use. This didn't happen with technologies in the past - 'real men' learned to double de-clutch. Most computers are hidden, and work behind the scene. Technologists see these things and marvel, but the average Joe Bloggs in the streets just finds things easier to work, or with a few extra features. Few people are conscious when driving a modern car, that computers are controlling the ignition, brakes and radio-tuning. These 'revolutionary' technical changes are just technical trivia. How do you compare these things with the impact on people and cultures from the 'transport revolution' of the early 1900's: horses almost disappeared from the roads, and trams, trains and motor cars replaced them. Suddenly everyone could travel -- from suburbs to the city, between towns, and even between states. Families were no longer isolated by distance; people had access to all forms of entertainment and recreation, most of which had only previously been available to the rich with stables. And it all happened in about the same period of time that we have been dealing with the computer revolution -- about 20 years. I think we need to get our feet back on the ground and stop imagining that we are more important than we are. ================ [TELECOM Digest Editor's Note: Mr. Fist, thanks very much for an excellent presentation of a point of view we often tend to overlook.

PAT] ------------------------------ Date: Mon, 3 Jan 1994 12:13:27 EST From: Jeffrey J. Carpenter Subject: Caller ID in Pennsylvania I received a copy of Pennsylvania Act 83 of 1993. This law permits Caller-ID in Pennsylvania as long as both per-line and per-call blocking are available. There may be a charge for per-line blocking, but not for per-call blocking. There are a number of parties that are excluded from charges for per-line blocking, including victims of domestic violence, women's shelters, and health and counseling centers. People ordering phone service may get per-line blocking at no charge within 60 days of ordering service. It permits a service that will automatically block calls from lines with blocking, and permits selective unblocking of lines with per-line blocking. There are a number of blocking exceptions for PBX's, 911 services and 800/900 services. Telephone companies offering this service must notify their customers sixty days in advance of the implementation to allow subscribers to obtain per-line blocking. jeff ------------------------------ Date: Mon, 3 Jan 94 14:45:44 EST From: add@philabs.Philips.Com (Aninda Dasgupta) Subject: Wireless Transceiver Boards I want to design a wireless data network for indoor (office space) applications. I want to use as many off-the-shelf products as possible. The first item I need is a wireless transceiver. The requirements are: 1) should work around corners and through walls (a range of say three to four rooms/offices), 2) support a data rate anywhere from 10 to 64 Kbps, 3) should use carrier frequencies that are not restricted by the FCC and are unlikely to be very crowded by other systems, 4) should be priced around $10. I would like to get off-the-shelf boards to which I can hook up my micro-processor based systems to build wireless nodes on the network. Can anyone point me to manufacturers of transceiver boards? Requirement one means that I can't use infra-red. I should probably use RF. How about the 900 MHz systems? The FCC allows only a few tens of watts of power in the 900 MHz range. What frequencies do other such systems (e.g. Echelon) use and what power levels do they provide? Model airplanes and toy cars use RF remotes. So does the BOSE home audio remote controller. What freq. and power levels do these use? Any help or comments will be greatly appreciated. I will summarize if I get sufficient replies. Thanks in advance.

I used to have lots of numbers like this, but they all seem to have disappeared. For example, there used to be one where you could leave whatever strange sound effects or messages you wanted, and they would periodically edit and splice them into their new outgoing greeting. And there used to be a number in San Francisco called the Earthquake Prevention Hotline, with a different oddball comedy bit every couple days. All I have to offer so far is They Might Be Giants's Dial-a-Song number, (718) 963-6962. And dialing 1073214049889664 gets you a computer voice that reads you your own phone number, in case you forgot or something. (This works from San Jose, CA, and I'm told it's toll free but I couldn't swear to it.) Please post or email any interesting numbers you may know of. (Obviously, please, no answering machines that might sometimes be answered by a human.) Thanks! Earl Vickers earl@netcom.com [TELECOM Digest Editor's Note: A couple of numbers I'll add to this list are 312-731-1100 and 312-731-1505. Both are operated by a fellow named Sherman Skolnick in Chicago who is a 'conspiracy buff'; you know, one of those people who believe that everyone but Oswald killed JFK. Both are five minute recordings, and he changes the two messages two or three times per week.

Thanks, joeshmoe@world.std.com Jascha Franklin-Hodge ------------------------------ From: jhaynes@austin.ibm.com (Jeffrey L. Haynes) Subject: Connecting Two Phone Lines to One Phone Jack Date: Mon, 03 Jan 1994 21:13:38 GMT Reply-To: jhaynes@austin.ibm.com Organization: AIX Defect Support I am trying to figure out how to wire two phone lines into a regular phone jack. Is this possible? I thought it was because only two wires are used. I have tried connecting the yellow and black to the red and green on the second line, but that doesn't seem to work. Anybody know anything about this stuff? Thanks, Jeff Haynes email: jhaynes@austin.ibm.com AIX Defect Support [TELECOM Digest Editor's Note: Well, I guess we know a few things about it Jeff. You do not want to connect the yellow and black wires to the red and green; that causes both lines to get shorted out. R/G is typically the first line (of two in a two pair cable) and Y/B is the second line. (I'm talking like an American now; forget about Europe or other countries for the purpose of this discussion.) You bring Y/B to your phone in the same way the R/G are brought there, but as *separate and distinct* things. You need a second phone instrument or at least a phone with two distinct lines on it in order to use the Y/B pair of wires, and that is presuming of course that telco has the wires connected at their end and in service. If you have two lines from telco, then what you do is at the modular connection box depends on the kind of phone(s) you are using. If you have a true two-line phone, then connect the four wires to the four screw terminals as indicated by the color markings for each. In addition you attach the four wires from the cover of the modular box to the associated screw terminals in the same way. Plug in your two line phone and it should work okay. If you are using two separate phones, we do it a bit differently. Inside the modular box, have the four wires connected as above, but from the Y/B terminals, run two little jumper wires to a second modular box you bought from Radio Shack or similar. Connect the jumper wires from the Y/B screws of the first box to the R/G screws in the new, second modular box. Now plug your second phone into your second box. The reason we wire the jumpers from Y/B in the one to R/G in the other is because R/G is traditionally known as the 'first line' and Y/B is traditionally known as the 'second line'. Most devices which handle only one phone line (i.e. a single-line phone instrument, an answering machine, a modem, etc) are wired internally to operate on the 'first line'; that is, to respond to and connect with R/G. So if you plan to use the 'second' (or Y/B) line for a modem or answering machine or fax machine, etc you need to give it whatever phone service you are going to have there on the 'first line' as far as it can tell, meaning see to it that the R/G on the newly installed modular terminal box gets the feed, ** but in a separate modular terminal box **. Never allow any of the four wires to touch each other. If more questions arise in this project, please write again. PAT] ------------------------------ From: yang@mundoe.maths.mu.OZ.AU (Yang Yu-shuang) Subject: Questions About VOXSON 899 Mobile Phone Organization: Computer Science, University of Melbourne, Australia Date: Tue, 4 Jan 1994 01:47:37 GMT Hi Net Friends, I bought a VOXSON CELLVOX 899 mobile phone recently. I have a few questions about it: (1) It comes with a 12 VDC 1000mA adaptor plug into the desktop charger. Is the adaptor just the ordinary AC-DC adaptor? Can I use the car cigarette lighter instead of the AC-DC adaptor? (2) I am thinking of making a small charger to be used in the car. What are the points to note? Can the battery be treated as the ordinary NiCad battery? (3) The battery has six metal pieces. Two of them are in contact with the phone which power the phone and four of them are in contact with the charger. The four in contact with the charger are labeled as "-", "S", "T", "+". What does those labels mean? (4) I noticed that the same type of phone in different shops carries different labels. For instance, the phones sold by Strathfield has a sticker saying "produced in Australia" while the ones in Myer has a sticker saying "made in Japan". The phone and the model number are the same otherwise. Are there any internal differences? Thank you in advance for any suggestions. YS (Sam) Yang yang@maths.mu.oz.au [TELECOM Digest Editor's Note: You can use any 'clean' (i.e. regulated) DC power supply rated at 10-13 volts and at least one amp, although my Micronta 13.8 VDC power supply is rated at three amps. Your car battery via the cigarette lighter will work fine. You don't need a charger in the car; just use a connector which fits the cigarette lighter on one end and your cellular phone battery charge connection on the other. As long as the motor is running your car battery will juice up the phone battery and let you use the phone as well. The plus and minus signs are for the positive and negative sides of the battery; most likely the S and T have to do with whether or not your phone is (or can be) wired into the circuitry of the car so that an incoming call will cause your horn to sound or your lights to flash if your car is parked somewhere and you are outside the car with the phone left in the vehicle turned on. Are you *certain* there are only two connections between the battery and the phone and not at least three or four of the six which reach the charger? It could also be that the S and T connections are like thermal switches -- when the battery gets fully juiced up it gets a little warm and some cellphone batteries use a thermal coupler to shut off the charger when the battery says it is no longer needed. There are probably no significant differences in the internals of your phone and those from Japan or Korea or Hong Kong or China or the local Radio Shack, etc. PAT] ------------------------------ Subject: US West's India Project Delayed by Foreign-Investment Debate Date: Mon, 03 Jan 1994 18:54:51 -0500 From: Atri Indiresan This report is from the India-D listserv group. I do not have the original citation for the article. Atri ------ US WEST'S PROJECT IN INDIA IS DELAYED BY DEBATE OF FOREIGN-INVESTMENT POLICY US West Inc.'s pioneering proposal to offer an alternative to India's state-owned phone system has been put on hold. The regional project, which would amount to a revolution in India's tightly controlled telecommunications industry, has run into opposition from some members of India's parliament and from unions representing workers in the state-owned network. US West proposes offering an alternative to the government-run network in parts of India's southern state of Tamil Nadu. Also on hold are 17 similar proposals lined up behind U S West's initiative, which received approval last month from the Foreign Investment Promotion Board. Technically, the project has been returned to the investment board for certain evaluations. However, a senior official has said that no clearance will be given until the government reaches a consensus on the role of private and foreign investment in the telecommunications industry. The unions say basic telecommunications services shouldn't be opened to competition. They have the support of some left-wing parliament members and are threatening to strike if there is a change in policy. However, a policy change is just what is needed, says Nagarajan Vittal, head of the Department of Telecommunications. He has been pushing for one since assuming his post in October. Now, his proposals are awaiting consideration by Prime Minister P.V. Narasimha Rao and his cabinet. If the review goes as expected, a new policy is likely to be announced before the end of January. Mr. Vittal argues that there is no alternative to opening up basic services to competition. He dismisses as inadequate a 400 billion rupee ($12.85 billion) plan he inherited, which would increase the country's phone lines to 20 million in 200 from the current seven million. That plan would still leave a waiting list of two years, compared with today's five or six, he estimates. "We should target 1.2 trillion rupees ($38.54 billion) to bridge this perennial gap," Mr. Vittal says. India has less than one telephone per 1000 people. The global average is 10.5. Mr. Vittal wants India to have 20 million lines by the end of 1995. But because India lacks the resources to finance such expansion on its own, he wants to admit foreign investors. "I want India's telephone density to be at world levels and to provide telephones on demand," Mr. Vittal says. "The quality of services must go up, and that can only happen with competition." According to Boli Madappa, U S West's director of international network projects, the first stage of U S West's plan would create 430,000 lines with an investment of $90 million in and around the textile exporting town of Tirupur in Tamil Nadu. In the second stage, to be completed by 2004, the total investment would rise to $176 million and the number of lines to 930,000. U S West would provide basic telephone service, as well as data services, public call offices and cable television. Several companies seeking to enter the market are closely watching the outcome of the U S West proposal. According to Mr. Vittal, American Telephone & Telegraph Co. has offered to eliminate the waiting list in 71 towns by providing competitive services, and Motorola Inc. has offered a "waitlist-buster" proposal that, among other things, would be designed to clear the waiting list in New Delhi, India's capital, in six months. ------------------------------ From: lincmad@netcom.com (Linc Madison) Subject: Dialing 1 First Prohibited in Dallas Organization: NETCOM On-line Communication Services (408 241-9760 guest) Date: Mon, 03 Jan 1994 22:41:40 GMT Several people have written recently about ten-digit dialing schemes for local calls to adjacent area codes. The idea is to preserve the concept that any local call can be dialed without a '1' even if prefix shortages make it no longer possible to dial just the seven-digit number. In most cases, you are permitted, but not required, to dial the 1 anyway, and all telcos are recommended to allow 1 + NPA + number for all calls within the NANP, including local calls within the same NPA. I was recently in Dallas, where you *must* dial: 7-digit number local, same area code NPA + 7-digit number local, different area code 1 + NPA + 7-digit number all non-local calls If you dial, for example, 1-817-265-xxxx instead of 817-265-xxxx, you get an intercept recording telling you to dial again without the 1. If you dial 1-214-nxx-xxxx instead of nxx-xxxx for a local call, you get a similar intercept. There is some logic, at least, in saying that any call that incurs a toll must be dialed with the 1, and thus that any call that does not incur a toll *may* be dialed without the 1, but there is just no excuse whatsoever for *prohibiting* the 1 for local calls. I only tried this from GTE Southwest, not from Southwestern Bell, since my parents had to accept exile to be within commute distance of my father's new office location. It is possible that SWB does better on this point, as well as in every single other facet of telephone service.

Esteemed Editor, This is a followup to my posting concerning the new 411 service in Atlanta. In response to an e-mail request to post more details to the Digest about subscriber requests which don't exactly fit the telco's DA template, here is a selection. Bear in mind that the operator doesn't dare just brush off the subscriber. That may bring a complaint. But if the call takes too long, the operator's AWT (average work time -- the average duration of the calls at the operator's position) will go up, which is also evil. So everything has to be either solved or at least properly redirected, preferably in 20 seconds or less. First, there are some frequent errors, such as subscribers asking for DA in another area code. A subclass of of these are the telephony- challenged. The operators usually read out the entire sequence for the call to the subscriber ("Dial one, then , then ..") and in one case the subscriber obediently hit DTMF 1 ("ma'am?" "Yes?" "You have to hang up first.") Second, there are ambiguous or poorly-stated listing requests. These can be mildly humorous: "I'd like the number of X in Jefferson" "Which one, ma'am? I have two Jefferson listings for that name." "Well, it's the one on the main street." "Neither is listed as having Main Street as an address." "No, it's the main street, it runs right through the center of town." (pause) "Ma'am, I don't know the name of that street." "Hmm. Well, it's the one that turns into the state road a little out of town ..." This can go on and on. Others would get me fired for talking back to customers if I had to put up with them: "Well, that's what _I_ always call my bank, and _they_ always know what I'm talking about!" Then there are some which are telephony-related, but not DA calls, like the bozo who badgered the operator endlessly about whether he'd get charged for a DA call made from his cellular phone. Or requests for beeper numbers. Finally, there are the miscellaneous requests: - what time is it? Not, what is the number to get the time recording? The subscriber was very explicit. - when do the buses run? - what zipcode is ? - and the winner: "Could you tell me what research is going on at Emory University?"

Please rotate your telephone ninety degrees and try again. [TELECOM Digest Editor's Note: Indeed, directory assistance operators (in fact, all telco operators) get a tremendous amount of abuse in a day's time. As Ms. Murphy, my former next-door neighbor and retired IBT operator once told me, "I thought something was wrong if I hadn't been cussed out by at least two or three subscribers before noon each day ...". Murphy was the very first union steward for the operators in Chicago over a half century ago; back in the days when 'everyone knew' no one would ever organize "the Bell" ... too big, too large, it just can't be done ... Murphy helped do it and after some forty years in the service of Ma Bell she retired in the early 1960's. She said to me she often missed the subscribers cursing at her all day long. :) PAT] ------------------------------ End of TELECOM Digest V14 #2 **************************** Received: from delta.eecs.nwu.edu by MINTAKA.LCS.MIT.EDU id aa19231; 4 Jan 94 7:21 EST Received: by delta.eecs.nwu.edu id AA25031 (5.65c/IDA-1.4.4 for telecom-recent@lcs.mit.edu); Tue, 4 Jan 1994 03:52:53 -0600 Received: by delta.eecs.nwu.edu id AA30138 (5.65c/IDA-1.4.4 for /usr/lib/sendmail -oQ/var/spool/mqueue.big -odi -oi -ftelecom-request telecomlist-outbound); Tue, 4 Jan 1994 03:52:25 -0600 Date: Tue, 4 Jan 1994 03:52:25 -0600 From: TELECOM Digest Message-Id: <199401040952.AA30138@delta.eecs.nwu.edu> To: telecom@eecs.nwu.edu Subject: TELECOM Digest V14 #3 TELECOM Digest Tue, 4 Jan 94 03:52:00 CST Volume 14 : Issue 3 Inside This Issue: Editor: Patrick A.

Inc., Middlebury, CT What follows is a bulletin from General DataComm regarding the availability of our V.FAST modem. For LITERATURE ONLY, please call 1-800-777-4005 (outside the US, call (203) 792-0542). For TECHNICAL or PRODUCT questions, you may either fax your queries to (203) 758-9129, or send e-mail to vfast@gdc.com. Please include a daytime phone number. Please mention that you heard about it in TELECOM Digest. ---------------------------------------------------- General DataComm, Inc. 1579 Straits Turnpike. , Middlebury, CT 06762-1299 INTERNET BULLETIN GDC ANNOUNCES V.FAST MODEM AVAILABILITY Middlebury, CT, December 30 -- General DataComm has just announced immediate availability of their new V.F 28.8 Series modems. These modems operate at full duplex speeds of 28.8 Kbps (Kilobits per second) in each direction, with compressed file speeds exceeding four times that rate. Currently shipping V.F 28.8 models are the DeskTop standalone modem and SpectraComm 7" high density rackmount version for central site installations. The DataComm V.F 28.8 standard rackmount model will be available in January. These modems are guaranteed to meet the new V.34 ITU-T recommendations as soon as it is ratified. Units purchased now will be upgraded, free, over the phone line. With 2- and 4-wire, synchronous and asynchronous, dial up and leased line operations, these may be considered universal modems. Containing the ITU-T V.21, V.22, V.22bis, V.32, V.32bis, V.34 and Bell 212A and 103 modulations and V.42/V.42bis error detection and correction with data compression, this modem covers speeds from 300 bps to 28.8 Kbps, with effective throughput up to 128 Kbps with data compression. V.fast - V.fastest! Currently there are few actual 28.8 Kbps modems in the market. Testing the DeskTop V.F 28.8 Series against two of these has shown GDC the clear winner in the speed race. From random, incompressible files, to data base and graphics files so common in LAN and multi-media applications, GDC bests the competition by as much as 100%. With over twice the speed in many applications, using lines that are typical of over 50% of the U.S. dial-up network, the results clearly indicate GDC modems provide the best high-speed solution. These tests are currently being confirmed by an independent testing laboratory. Speed Saves For modem users, this means that with graphics and database file transfers, they will be cutting their phone bill in half using GDC's modems over the other V.fast solutions, and saving significantly more over V.32bis or slower modems. Companies and individuals looking for high speed modems to meet their applications requirements, are sensitive to these cost issues. Buying the wrong modem could cost many times the price of the unit. In fact, it may be shown that, even if you were given a competitive modem at no cost, it would pay to purchase a GDC unit. The GDC V.F 28,8 Series may also be equipped with high speed interfaces - both ITU-T V.35, ITU-T V.24/V.28/ISO2593 and EIA/TIA 530-A, ITU-T V.10/V.11/V.24/ISO 2110 are available for international and domestic use. This is very important, since these interfaces may be required to actually achieve the inherent speeds available using these new modems. With approvals already received for more than 30 countries, and more on the way, the GDC V.F 28.8 should be considered the international modem of choice for multi-national concerns. FLASH Flash All GDC V.F 28.8 Series modems are currently shipping with FLASH memory, allowing feature enhancements to the modems to be implemented by upgrading the software electronically, rather than swapping PROM chips. This means that obsolescence is a thing of the past, and users will be able to keep their modems up-to-date by making a phone call and downloading code for: - invoking new features - implementing code enhancements - insuring compatibility with the V.34 standard - establishing connectivity with new software communication packages and other devices. Many of today's modems are based on modified V.32bis chip sets incorporating proprietary modulation firmware which cannot be upgraded to V.34 when the standard is ratified. Phrases like "V.fast technology", "V.32terbo", "V.fast Class" are commonly used to infer compliance with the V.fast recommendations. This may not, in fact, become a reality when the standard becomes available. GDC guarantees its modems can be upgraded to the V.34 standard via download. Competitive modems still have to physically update the hardware as well as the software when upgrading products. Loss of the use of the modem while transporting it to and from the manufacturer for upgrade, disruption of service while the service technician replaces the chip and tests it, and the costs of providing services during these times are typical costs associated with other modem updates for your prospect. "These costs are avoided using the new GDC software upgrade technology. With GDC, a phone call does it all." says Dick Drake, Director of Marketing for Transmission Products. In January, GDC will begin compliance testing with the proposed V.34 standard, insuring GDC will be ready to implement the changes necessary when the standard is ratified. In addition, there are a number of new features already in the works. These include: Automatic Dial Restoral (ADR) for backup of leased lines with dial circuits; Password and Security Callback; V.25bis serial dialing (sync and async); and Remote Configuration of modems from other locations. How Upgrades Work There are two characteristics built into the V.F 28.8 that allow upgrades to be achieved over the phone line. First is the ability of the hardware, in this case a universal communications platform, to change it's functionality based on the resident software provided. The second characteristic is the ability to download the modem-defining software by connecting to the GDC Bulletin Board (BBS). The new software containing the desired features and operational characteristics -- the modem personality -- for the upgrade are then loaded down to the internal FLASH memory of the V.F 28.8 modem. Since the modem has the capability of storing up to four custom configurations, along with four fixed pre-defined profiles, and up to ten customer-defined phone numbers, these are also saved so the customer retains all unique operational parameters during this upgrade process. Safety Concerns In addition to the approved modem standards, many modem customers are concerned with safety issues. The V.F 28.8 Series has passed UL safety tests for lightning protection (UL1459) and for flammability (UL94V0). And heat is not an issue. With less than six watts of power consumption, our V.fast modems produce much less heat than our competitors with 12 watts, or more. This translates into greater safety, reliability, and savings for the customer. Digital Impact In some cases, users may wish to use the new V.F 28.8 modems as a substitute for, or backup of, digital circuits. With effective throughput speeds exceeding 100 Kbps, applications abound: 1. The V.F 28.8 Series is ideally suited for backup of Switched 56 Kbps analog or 64 Kbps digital leased lines using the dial-up network. Speeds are now compatible with many LAN-to-LAN applications. This insures both reliability and cost efficiencies. 2. Many managers are taking a hard look at the costs of upgrading to an all-digital network. Some of the benefits they see by staying with high-speed modems are: a. Modems fit in existing networks, and can be incrementally added as required versus installing a whole new digital system. b. Modems provide the only universal connectivity worldwide. c. Installation, training and support are all minimized with modems versus having to retrain, re-equip, and re-educate the department when switching to new technology. d. Modem technology is inherently more cost effective. e. Most MIS managers are more "comfortable" with modem technology, and the GDC V.F 28.8 Series may be changed into a managed modem with minimum network disruption with a simple download. Equipment obsolescence is virtually eliminated. 3. Generic applications, using modems as just another design element, are appearing from non-traditional sources. Applications from medical (CAT scan data transfer), to multi-media (training and manual field updates) are appearing daily. Many of these, due to larger file sizes, require higher speeds and universal transport - ideal for the GDC V.F 28.8 Series modems. 4. Most large users have occasion to work overseas. Many are multi-national. The GDC V.F 28.8 Series is currently homologated (approved for use) in thirty countries. In most cases, GDC is the only game in town (and country). "It would be a shame for a user to get new V.fast modems for his U.S. offices and then find out that his overseas offices, where he spends big communications bucks, can't use all the available speed because they implemented a proprietary system with a modem not approved in this country." said Drake. General DataComm, Inc. is a leading provider of multimedia networks and telecommunications equipment worldwide. Based in Connecticut, GDC serves corporate customers and telephone operating companies throughout the Americas, Europe, the Middle East, Asia and Australia/New Zealand. ------------------------------ From: weiyun@extro.ucc.su.OZ.AU (Weiyun Yu) Subject: US Digital Cellular Standard Organization: Information Services, Sydney University, Sydney, NSW, Australia Date: Mon, 03 Jan 1994 00:35:12 GMT It has come to my attention that the digital cellular standards adopted by US carriers are not going to be compatible with what we have adopted in Australia, GSM. I am interested in finding out a bit more about the US systems but cant find any FAQ on the subject. My specific questions are: 1. What are the pro and cons of the US standards vs GSM. 2. Is there going to be some degree of compability encorporated into the 2 standards so that international roaming could be achieved. 3. What is the future of digital cellular? Is there going to be a third standard that can be used world wide? Does anyone know the answers?

Fowler <0003513813@mcimail.com> Subject: Landlines Pay Airtime To Call Some Cellular Phones The following is from an interesting insert in my December telephone bill. A SPECIAL NOTICE TO OUR CUSTOMERS IN COLORADO: EFFECTIVE JANUARY 1, 1994, YOU WILL BE BILLED FOR CALLS YOU MAKE TO CERTAIN CELLULAR TELEPHONE NUMBERS. If the cellular phone you are calling begins with 1 + 579, you will be billed for the cellular airtime charges and also any long distance charges associated with the call when applicable. Like most other 1+ calls, there will be a charge for placing calls to these cellular 1+ numbers. The cost of the call will depend upon the cellular customer you call. (The charges for these calls are deter- mined by the cellular carriers, not by U.S. West.) If there are any questions about cellular airtime charges that appear on your bill, to the above prefix, please call the Customer Inquiry Center at 1-800-USW-BILL. A couple of comments: Colorado is one of those states where any non-local call requires that a 1 be dialed before the number. Currently, 1 + 7D can be used, but 1 + NPA + 7D will need to be used after February 27, 1994. Also, the use of the 579 prefix may not apply to other states. For example, my mother, who lives in Dixon, New Mexico, has a regular phone number on the 579 prefix there. I wonder what kinds of people will be using "caller-pays" cellular service. John C.

Date: 03 Jan 1994 10:22:36 -0800 Organization: CRL Dialup Internet Access, California Reply-To: lchiu@crl.com I plan to travel to mainland China in the near future. I am hoping to be able to use a cellular phone in the area but from distant recollection I think they use GSM. I don't know of any US provider that uses GSM and hence would have no idea how to purchase a phone that uses that standard. Does anybody have any ideas on how to get one? Purchasing one in China would be exorbitant I would imagine. An an aside I think Hong Kong uses AMPS and with the massive amount of trade between Senzhen (sp?) -- the new economic zone in southern China, I wonder what system they use there?

Perhaps one of our readers versed in French will translate the above for me, and I'll run the English translation in a day or two. It is not that common for books to be banned in the United States. Generally the only time a book will be censored (or banned outright) in the USA is when the govern- ment feels very threatened by it. Two which come to mind are "The CIA and the Cult of Intelligence" and "The Politics of Heroin in Southeast Asia". Both were written by former operatives of the Central Intelligence Agency when George Bush was in charge of that agency. In both instances the government convinced a court that publication/distribution of the book would be quite harmful to the government's interests. When the books were finally allowed to be published they contained large amounts of blank space -- entire pages were completely blank in places -- as the authors and publishers attempted to comply with the court order while still printing *something*. When reading the books, I'd be on a page and halfway through a paragraph; the printed text would stop and resume perhaps an inch or two down the page with a note in the middle saying the text originally planned to appear there was removed by court order. In one section, the text stopped halfway down the page, and about a dozen completely blank pages followed with the text resuming about two- thirds of the way through the thirteenth page with the same notation on each of the blank pages. The books were deliberatly published that way with the gaping holes in the text throughout to show the public the large amount of stuff the government had censored. I believe the authors remain under government-imposed silence even today, over two decades after the books were written. Is there anyone in this room old enough to remember when {Ramparts Magazine} published AT&T's calling card check-digit secrets back in the middle 1960's? AT&T went to court at the time of publication and got an order banning that issue of the magazine.

John D. Gretzinger Sprint doesn't speak for me, and I don't speak for them. <<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>> Forwarded message from PC SprintMail: STATEMENT FROM WILLIAM T. ESREY, SPRINT CHAIRMAN & CEO IN RESPONSE TO MCI "NETWORK CATCH-UP" ANNOUNCEMENT "Sprint is not at all surprised by MCI's network catch-up announcement. More than a year ago, Sprint announced its broadband network plans to deploy SONET and ATM. We were the first to offer commercial ATM service in August 1993. We continue to have the most modern network and remain as the only 100 percent digital, fiber-optic long distance carrier. "MCI is very good at packaging announcements that make mountains out of molehills. Sprint hopes the public will take this latest ploy for what it is -- a slick admission of being behind in terms of technology deployment. "On the other hand, MCI's foray into local access has some merit. Sprint long has endorsed expanded local competition and believes MCI's efforts may be one in a long series of steps necessary before local competition will exist. Network Upgrades "We agree with MCI that it's going to take a lot of people working together to build the information superhighway. Sprint welcomes MCI and others aboard this significant effort. "An important first step in the investment in the National Information Infrastructure is the development and expansion of the network. "We announced our strategic vision for our advanced network a year and a half ago and are the only carrier implementing a broadband data strategy. We were also the first carrier to announce plans for SONET, which we revealed over a year ago. Since that time, we have moved from opening up pipes, which is the basis of today's announcement, to the many exciting applications that are driving the National Information Infrastructure concept. "The examples are numerous. For example, our InterNet capabilities are unrivaled. Sprint offers the most widespread Internet connectivity through SprintLink(R) network -- the first and only TCP/IP network service for commercial and government Internet users to be offered by a carrier. This service has expanded to offer international connections and forms the core of the global Internet, with two-thirds of the international Internet traffic to and from the United States being carried on SprintLink. This service originated from a cooperative agreement between Sprint and the National Science Foundation to provide international InterNet connections to the domestic InterNet. "Sprint has been and continues to be the leader in introducing leading edge technologies, which are the 'building blocks' of the information superhighway, to the marketplace. We led the industry by being the first major long distance company to deploy frame relay, and we have more frame relay customers than any of our competitors. We were also the first to deploy ATM service and our first customer turned up service last year. "Our leadership in this key technology has been widely recognized -- most recently by the government by being selected to provide ESNet for the Department of Energy and NASA -- because of our unique ability to offer ATM. "That recognition as the technology leader in ATM extends to the telecom industry, as well as the academic and government communities, by being the only company selected to provide ATM for the National Information Infrastructure Testbed. NIIT is a consortium of business, government and academic leaders working together to speed the delivery of the information highway. "Our ATM leadership, in conjunction with our 1993 deployment of SONET, will ensure that Sprint continues to build on its reputation as the advanced networking leader. Local Access "The virtual monopoly that exists today in local access is troublesome for the long distance industry. Currently, more than 99 percent of long distance traffic originates and terminates over facilities owned by local telephone companies, principally the Regional Bell Operating Companies. Long distance competitors are at the mercy of local telcos, since they are the only way to reach our customers. Today, about 45 percent of the cost to carry a long distance call is a direct payment to the local telephone company for the 'last mile' connection. "Sprint has been an advocate of expanded competition in local access primarily because of the excessive cost of access charged by the RBOCs in their respective operating areas. "MCI's plan to build local access networks in major metropolitan areas could be another step toward local competition. Competition will not happen overnight, however. It took more than 15 years of constant litigation and ultimately the breakup of the Bell System before competing carriers were able to establish a meaningful presence in long distance. The local monopolies of the RBOCs are at least as strong as the monopoly enjoyed by Bell in long distance prior to divestiture. "MCI's plans, no matter how grand, should be viewed much the same as the plans for local access that have been announced by cable television, cellular and PCS providers -- positively, but without expectations of near-term impact. "The issue of RBOC entry into the interexchange market does not change with MCI's plans. True competition for local access is still many years away. Until there is actual and effective competition in the local loop and the bottleneck is broken, the RBOCs should not be allowed to act as both competitors and virtual sole source access providers to long distance carriers. When the means and opportunity for the RBOCs to discriminate against long distance competitors is lifted through competitive local access, then, and only then, should the restrictions on the Bell companies be lifted." Jan. 4, 1994 ------------------------------ Date: Tue, 4 Jan 1994 10:33:40 CST From: "Andrew C. Green" Subject: Magazine Telemarketers From (Heck) As a member of what are apparently some very popular demographic categories, I get a constant stream of telemarketing calls. Most are semi-intelligent types who drop the effort when we decline the offer, but recently we've had a string of bozos all originating from one source, and before I go on the attack, I thought I'd poll the forum here for anyone else who's had the same experience. I recently renewed my subscription to "Car and Driver" magazine, a publication boasting circulation of something like 1.1 million, if memory serves. At about the same time, I received a call from a true whacko who thanked me for resubscribing to C&D, then offered me one of those multi-magazine subscriptions where they quote you a low weekly rate (failing to mention that the monthly charge is higher than individual subscriptions direct from the actual publishers), plus a set of Ginsu steak knives. Yes, really. He got insulting when I pointed out that his math didn't add up and that Car and Driver probably did not appreciate his trying to sell "Road and Track" subscriptions from their mailing list. Last night I got another call from a girl who also thanked me for my C&D subscription, then tried desperately to foist a 16.9% Visa card at me. No, thank you, said I. "But it's pre-approved!" she shrieked, apparently not aware that gainfully-employed people get those things all the time. ;-) Not _two_ _hours_ later, an elderly lady from "DialAmerica Marketing" called. You guessed it: she thanked me for my Car & Driver subscription, and would I like to extend it at the 1993 rate? She disavowed any knowledge of the preceding Froot Loops, which I sort of believed, as it appears that Car & Driver has painted my phone number on an expressway overpass somewhere, and promised to relocate my number to their "Do Not Call" list. Nevertheless, this magazine has far surpassed all others on my Telemarketing Annoyance scale, and before I start complaining to the magazine, I'd be interested in hearing from any other TELECOM Digest/Car and Driver subscribers who have experienced the same thing. E-mail is fine; I'll submit any interesting followup news in the future. Andrew C. Green Datalogics, Inc. Internet: acg@dlogics.com 441 W.

It may be that Kermit is popular because it is available for pretty much any computer you can name (and a bunch that you can't). It may be that Kermit is popular because it is free. Or, it may be that Kermit is popular because of the (written) communications skills of Christine Gianone and Frank da Cruz. As Kermit is both protocol and communications program, so this book is an introduction to computer communications, protocol specification, introduction to the Kermit implementations and programmers' reference guide, all rolled into one. An ambitious task, but one handled with grace and skill, in this instance. Part one gives us the basics of the development of Kermit and of data communications from the user's perspective. This confirms that, yes, the name was inspired by the Jim Henson muppet character (or, more exactly, by a Muppets wall calendar). One hopes that Jim Henson approves of this memorial. Chapter two does not get into exhaustive detail on computer (mostly PC) communications, but does cover the fundamental steps and needs with more brevity, completeness and wit than one sees in many works intended for the mass market. (I am sorry to see the confusion of "baud" and "bits per second", although the two terms are correctly defined in the glossary.) Part two gives us two primers; one on computers and data files, and the other on data communications. The section is well named. Both chapters are easily understood by the novice and provide the minimum necessary information to proceed from. Excellent pieces, both of them. Part three is an introduction to using Kermit. Chapter five describes a set of the most commonly used commands, including an introduction to the simplest login scripts. Chapter six discusses common problems while seven deals with the possibly thorny issue of getting Kermit into your machine in the first place. Included in this last chapter is a BASIC source code program for a "read only" Kermit protocol for downloading files. Part four is a guide to writing a Kermit implementation. Quite a complete guide: not only does it give you the protocol specification (which is still *the* protocol specification) but also optional features, advanced options and even tips on programming style. Appendices give you the bulk of the Kermit source code (in C), a command summary, packet summary, the ASCII character set and a discussion of binary, octal and hexadecimal numbers and notation. If you want to build your own implementation of Kermit, this is the book for you. If you care nothing for programming, and have only bought your computer in order to "get online", this is the book for you, too. (Be sure to get "Using MS-DOS Kermit," too.) (cf. BKUMSKMT.RVW) For those in between, this is an excellent resource to have around to answer those "how does work?" type questions. copyright Robert M.

I have an antique extension phone that I'd like to connect to my phone system. It's a small black desk set, with no dial, but there is a blank for one. On the back, below the hook, is stamped the legend "D1 USA". Inside, "K-7" is stamped into the metal and "IV 37" is printed in red paint. The handset is labelled "Western Electric [tm etc] E1". The cord from handset to base is fabric-sheathed, and contains three rubber-sheathed wires: red, white, and black. Inside, the hook operates two leaf switches. The black and white wires are each attached to just one of the two leaf switches; i.e., black to one switch, white to the other. The red wire is attached to a terminal by itself. The line cord is missing; the empty terminals on the switches are marked for green (GN) and yellow (Y) wire. I don't want to add a ringer or a dial; I'd simply like to be able to use this phone to answer a call when I hear another phone ringing. If anyone can tell me what I need to do to connect this to a modern phone system, I'd sure appreciate it -- and so would my mother! :) Please cc: replies to macwhiz@cif.rochester.edu; I am on vacation and won't be reading news often, but email will get forwarded to someplace I can reach it! :) Rob Levandowski Computer Interest Floor associate / University of Rochester macwhiz@cif.rochester.edu ------------------------------ From: gst@gagme.wwa.com (George Thurman) Subject: Old AT&T/Wsetern Electric Documents Date: Tue, 4 Jan 1994 05:37:18 CST Here is a message I saw on Fidonet that I thought TELECOM Digest readers would find of interest. *********************** Msg#:14544 *SHORTWAVE* 07-25-93 21:37:00 From: DON KIMBERLIN To: ALL Subj: AT&T INFO ON-LINE It's fairly often that someone comes across an old bit of Western Electric-made equipment from the heyday of the Olde Bell System, and lacks the needed drawings or instructions to try to make use of it. Perhaps the most common old items we hear people asking about are the old 1A Key Telephone Systems using 26-pair cable to hook the telephone sets up to their common equipment cabinets in a wide variety of configurations. Or, perhaps there are items of how things like managing trouble reports in telecommunications systems are handled, or what _are_ all those abbreviations and acronyms used by telephone companies? Or, perhaps you even need documentation for something newer, like a 3B2 minicomputer or a System 75 or 85 PBX ... or maybe you have a strange "data set" with a nomenclature like 201C or 2048, and would like to know if you can make use of it. There _is_ a repository of much of this information that's often handed down verbally or misquoted from memory. Today's name for it is the AT&T Customer Information Center, and it's located in Indianapolis, Indiana.

Earle <0006127039@mcimail.com> Subject: SWBMS to Reduce Roam Rates! Enclosed with my cellular bill from Southwestern Bell Mobile Systems, Corpus Christi, TX was the usual glossy newsletter. Of interest: Now it is more convenient and more economical to take your cellular phone with you when you're traveling. SWBMS is working iwth other cellular companies to give you lower roaming rates in over 350 markets, or approximately 25% of all cellular markets. Beginning in December, cellular companies will begin lowering roaming rates in two ways. First, the daily charges will be eliminated and second, the per minute rate will be reduced. You will save money based on the amount of roaming that you do. For example, if you travel to a market where the daily charge is $3/day and .75/min, you'll receive a tremendous savings. (Note: I'd be happy while roaming, with zero daily fee and any airtime rate < $1/min. This looks pretty good) SWBMS customers currently enjoy reduced roaming rates throughout Texas. When you are traveling in the Lone Star Cellular Network, you already pay a reduced rate of only .50/min. The LSCN is an exclusive service of SWBMS (Note: In GTE cities, Houston and Austin, the rate charged by GTE is .40/min. Although "exclusive" to SWBMS, Texas GTE MobilNet customers are also part of the LSCN for billing purposes when they roam in SWBMS cities. mwe) Through these agreements, you will enjoy the added benefit of using your cellular phone while traveling (Cynical note: We'll make even more monies!) and you will see what an added value a cellular phone can be. And you can be sure SWBMS will continue to lead the way by providing even better service to our coustomers. (OK, when is seamless roaming for the 'B' side coming? When will my features, forwarding, voice mail, etc. work while I'm roaming?) (Note: Any month there is roaming billed, a $3 "roamer admin fee" is added to the bill. With GTE, it's cheaper than roaming in SWBMS nearby systems, strangely. No list of cities comprising the 350 markets was provided). Typos my own: SWBMS always spelled out, I abbreviated it. Likewise LSCN. mwearle@mcimail.com ------------------------------ Date: Tue, 4 Jan 1994 23:56:14 -0800 From: Steve Freedkin Subject: Fundraising/Saving Program MONEY SAVING & RAISING OPPORTUNITY Hello, and happy new year! -- I want to let you know about an opportunity for organizations and individuals to save 10% on all their long-distance calling, and organizations to raise money with minimal cost and no obligation. The deregulation of long-distance telephone service created many opportunities, including this one, which should be of interest to those who follow telecommunications developments. | * GUARANTEED! 10% SAVINGS ON ALL LONG-DISTANCE CALLS | | * 5% OF YOUR CALLING BENEFITS NONPROFIT ORGANIZATION | I used to be director of a local nonprofit peace resource center that raised money through a service that saved our constituents money *and* generated royalties for us. The program is a long-distance telephone service that was started in 1990 to benefit nonprofits. The company, Affinity Fund, gives each customer rates *guaranteed* to be below whatever the person is currently paying for long distance, and at the same time gives the nonprofit that signs up the customer a 5-percent royalty on that person's long-distance usage every month. (Affinity arranges for the actual service to be provided by one of the nation's foremost long-distance carriers, so there's no difference in service quality.) Groups that are raising money this way now include schools, Central America support groups, community radio stations, Sister Cities programs, local and national peace groups (War Resisters League is one), nonprofit community newspapers and media services, etc. If you'd like information about Affinity please contact me and I'll pass it along. Or, please pass this note on to the appropriate person. Let me know whether you're interested as a customer who'd like to save 10% on all your long-distance; representing a nonprofit that might like to raise money using this method; or both. | If you *aren't* interested please ignore | | this message, and accept my best wishes. | Thanks for your attention, and have a safe and prosperous 1994!

INTRODUCTION AND RELIGIOUS STATEMENT The purpose of this document is to enable the hacker who wants to know everything about his DPC cellular telephone. It is based upon the belief that the bad guys already know this information, so keeping it secret doesn't do any good except to annoy those of us who want to know *everything* about our phones. Some of this information only applies to certain models, or varies from model to model. I entered the information for the model of DPC which I have. If you have a different model, either figure it out on your own or get ahold of the Motorola documentation and look it up there. Have fun with this information, but don't try to use it for illegal activity (fraud, harassment, illegal transmission). The cellular companies and the FCC are becoming quite aggressive (and skilled) at tracking such activity down. At best, your phone's ESN will be blacklisted nationwide; at worst, you could face federal criminal charges. The bad guys use stolen phones or phones with altered ESNs, and either toss the phone or alter the ESN after a day or so of misuse. This hole will be closed upon the completion of a North American ESN database which the cellular companies are busily setting up. On the other hand, feel perfectly free to tell a new cellular company (e.g. when you move to a new city) to buzz off when they want to charge you $25 to reprogram your phone. Tell them just to give you the various details of programming information you need (system ID, telephone number, station class mark, access overload class, group ID, paging channel, MIN mark, and local use mark) and do it yourself and save $25. Even better, if you decide to get an evaluation account with the other carrier, you can program your dual NAM without letting the new or old carriers know too much about your other account.

Intl. Conference, June 94 Organization: IFIP WG 9.3 Date: Tue, 4 Jan 1994 11:56:48 GMT CALL FOR CONTRIBUTIONS - CALL FOR CONTRIBUTIONS A cross-disciplinary international conference HOME-ORIENTED INFORMATICS, TELEMATICS & AUTOMATION From 'State of the Art' through 'Prospects' and 'Blueprints' to 'Implementation' organized by IFIP Working Group 9.3 in cooperation with the University of Copenhagen University of Copenhagen, Denmark June 27 - July 1, 1994 BACKGROUND The home offers a great potential for new automation, information and communication technologies and related services. A wide array of innovations are already under way, with many more to come. They will transform the home and everyday life in the emerging information society. They will condition how private households will be enabled to function in changing social, economic and political structures. AIMS AND SCOPE The conference will assess and conceptualize perspectives and options, which attach to developments of domestic informatics, telematics and automation across the levels of - consumer hard- and software, - network infrastructures - storage & distribution media, - teleservices and - socio-cultural & economic structures. How can these new technologies - seen together - be used to empower consumers and private households? How can both users and suppliers get the optimal benefits from the possible new technologies? - and with which global impact? Can these technologies contribute to the emergence of a new home concept, an "Oikos", where the private household can reestablish itself in an experienced way as a living and production centre, embedded in and interacting with a larger community? Addressing such questions requires a multi-disciplinary approach. Therefore the conference aims to bring together experts from many fields and disciplines. Researchers and practitioners, designers and users, policy makers and industrialists, each with new knowledge and new questions from their experience of recent and expected development. The conference will not only serve as a forum to present and exchange experience, results of research and ideas, but also to explore and discuss strategic approaches and alliances for product research and development, and for prototyping and field experiments. MAJOR THEMES * The social construction of new domestic technologies. * Bridging between the various disciplinary approaches. * The changing position and importance of households in the new social and economic structure of the information and communication society. * Strategies for creating professional and public awareness of the converging potentials and implications of constructive innovations for everyday life and for social, cultural, educational, health, energy, and economic policies. * Ways of organizing relations between research and product development which can further the long-term interest of consumers, and save produ- cers from waste of investments in development of products and services which are doomed to failure. * Relevance for developing countries, cultural diversities and the general goals of the UN year of the family 1994. MAIN AREAS Advanced Home Technologies (e.g. Intelligent home - Linking of TV, telephone, computer and VCR - Interactive multimedia and domestic virtual reality - Security-systems - Household appliances - Environmental control and ecology - Bio-electronics and health-monitoring.) Communication and telematics (e.g. Convergence of broadcast and telecom networks - Interactive teleservices and teletransactions - Tele-education - Telework - Evolving informal networks - Home-to-Home interfacing.)

Subject: Bandwidth to Russia Wanted Several of my friends and I working part time as agents for one of the telephone companies were able to get about 50,000 minutes per month of switched traffic from US to the former Soviet Union. SERVICE DESCRIPTION: The subscribers to our service do not have to switch their long distance provider. The subscriber simply dials 1-800 ... number and if his ANI is registered he gets a dial tone if the switch does not recognize the ANI (when the subscriber is calling from a payphone or a hotel) the subscriber is prompted to enter his Travel Code. Some customers have preset spending limits and are prompted before each call regarding the amount of credit they have left. PROBLEMS: The main complaints of our customers is that the service is not reliable. The switch is usually down several hours a day, many of the calls placed to the Former Soviet Union do not go through, FAXes cannot be sent. We feel that these reasons are preventing us from increasing our traffic and are contrtibuting to loss of customers. OUR WISH LIST: Here are some of the solutions we envision (listed in order of preference): 1) A direct E1 (or T1) trunk from US (preferably 60 Hudson St, New York) to Moscow, Russia. All of the 30 (24 for T1) circuits have to approved by FCC for switched traffic. We can arrange to distribute traffic from Moscow. We would prefer the lines to be multiplexed between 4:1 and 6:1. We approached several US telephone companies about leasing E1 or T1 and were given monthly prices that were about twice the prices quoted by some US companies in Moscow. 2) We are also willing to route all our traffic through some other provider if we can get some reasonable rate per minute and still are able to provide the same service as we are providing now (see SERVICE DESCRIPTION). If you can offer one of the above two services or have any ideas where we can obtain these services please send e-mail to : alex@mvision.com or call me at: (212) 306-0410 (work) (201) 575-8215 (home) (201) 227-5037 (fax) Alex Turkenich ------------------------------ From: dave@kentrox.com (Dave Read) Subject: Excel LD provider: Yea or Nay? Date: Tue, 04 Jan 94 10:44:49 PST Yesterday a friend put the full-court press on me to sign up with some long-distance outfit called Excel. I'd never heard of 'em, but he made it sound like your basic multi-level marketing scheme, get bucks when you sign people up, and more bucks when *they* sign people up, etc etc etc. Reminded me of Amway. :-) Anyway, any experiences/opinions? I presume they buy their LD service from the biggie providers (AT&T, Sprint, MCI etc), but beyond that I haven't a clue if Excel is on the level or not. Thanks, dave ------------------------------ Subject: Info on Cellular One NACP From: ctuttle@obelisk.pillar.com (Colin Tuttle) Date: Tue, 04 Jan 94 00:21:25 CST Organization: Pillar Communication, Oklahoma City, Ok I have a question regarding the Cellular One North American Cellular Network. I have Cellular One service in Oklahoma (McCaw Communications) and found the system works well passing my calls from Oklahoma City to Tulsa when I travel (about 100 miles but part of Cellular One's SuperSystem). Everyone who has called me on my Oklahoma City number gets me in Tulsa with no problems, delays, etc. Everything works the way it should. Now this past week I went down to Austin, (a NACN City) turned on the cell phone and immediately called my Oklahoma City number from a nearby pay phone. It rang twice and then my cell phone rang. Now my question is how does Cellular One Austin so quickly notify Cellular One Oklahoma City I am in Austin Texas about 400 miles from home and immediately send my calls to me? I assume when I turn on my phone the cell processes my ESN and sends the information either to its computer or my home system. What impressed me was how fast it did all this, and without me telling it to do this. Whatever system they use must also allow greater security, as if your phone is stolen they could immediately deactivate it around the country. Is this a FAQ, or could someone briefly explain how the Cellular One NACN actually works? The computing power to keep track of all of these ESN's must be great as well as passing all of this information from system to system obviously in real-time. ctuttle@obelisk.pillar.com (Colin Tuttle) Pillar Communications BBS, Oklahoma City, OK -- +1 405 942 8794 ------------------------------ End of TELECOM Digest V14 #5 **************************** Received: from delta.eecs.nwu.edu by MINTAKA.LCS.MIT.EDU id aa29662; 5 Jan 94 4:16 EST Received: by delta.eecs.nwu.edu id AA01271 (5.65c/IDA-1.4.4 for telecom-recent@lcs.mit.edu); Wed, 5 Jan 1994 00:54:29 -0600 Received: by delta.eecs.nwu.edu id AA06448 (5.65c/IDA-1.4.4 for /usr/lib/sendmail -oQ/var/spool/mqueue.big -odi -oi -ftelecom-request telecomlist-outbound); Wed, 5 Jan 1994 00:54:00 -0600 Date: Wed, 5 Jan 1994 00:54:00 -0600 From: TELECOM Moderator Message-Id: <199401050654.AA06448@delta.eecs.nwu.edu> To: telecom@eecs.nwu.edu Subject: TELECOM Digest V14 #6 TELECOM Digest Thu, 5 Jan 94 00:54:00 CST Volume 14 : Issue 6 Inside This Issue: Editor: Patrick A.

It is housed in the Telecom Archives sub-directory called 'indices' with a cross-reference located in 'back.issues'. This is the companion volume to the 1989-91 index which lists all the authors and subjects for volumes 9, 10 and 11. Look for them in the indices sub-directory under the title 'authors-subjects.1989-91' and 'authors-subjects.1992-93'. Should you wish to capture these files and print them out as hard copy for future reference, you should note that the first volume is 24,939 lines, or about 380-390 pages in length, and the second volume is 19,760 lines, or about 300-310 pages in length. The index is split into two volumes for ease in handling in case you want one part but not the other, etc. Users of anonymous FTP can take either or both volumes. Users of the Email Information Service will find that the command SEARCH checks both volumes in the process of returning reference results. Should you obtain a copy of the file(s) for yourself, please note that the following characteristics apply: The left column of numbers indicates the volume and *bundle of fifty issues* to be pulled for the desired topic. For example, if the reference given is 13/101-150, that means go to the back issues area and pull volume 13, issues 101-150. 09/501-550 would refer to volume 9, issues 501-550 and so on. The subjects are then filed in strict alphabetical order, with instances of 'Re:' ignored where they appear. Where two or more articles have an identical title (because there was an original article followed by one or more 'Re: Article Title' responses (and since 'Re:' is ignored, therefore the articles would appear to be identical), the sort further continues by author name, again in alphabetical order *by the first name* of the author. For example, an article by John Smith would be listed ahead of an article with the identical title by Paul Brown, because /J/ comes before /P/. You can also search the indexes (or indices as they are known to the email server to avoid conflict with the information file 'index') using the Unix command 'grep -i'. Due to some irregularities in the way articles were named and author's names included. I suggest a liberal interpretation of grep when searching the indexes. If your search criteria is too narrow, you won't get any hits. If your search criteria is too wide, you will get flooded with article titles you do not want. Experiment for the best combination. Technically, these are accelerated indexes because they do not point to the actual article in question but merely *to other groups of indexes and batches of issues* wherein the article(s) will be found. If something you wanted was found in 13/150-200 for example, you would then get the batch of back issues labled Volume 13 Issues 150-200 and check the Index contained at the start of each issue of the Digest to see if your article(s) were found there. Or of course you could then 'grep -i' the batch of fifty issues if you prefer. One final note: within the two volume index itself resides a limited help file with a few details to help with your searches. You can read this help file by grepping (-i) "HELP-". The first fifty or sixty lines of text in each file is the 'help' part. Each line in the help section begins with "HELP-". Whatever you grep for in these indexes is what you will get, so you can search article titles, key phrases which appeared in several article titles, author names, or by volume and batch-of-issues number if you wish. It is up to date through issue 844, the final issue of 1993. This was quite a labor of love, and I am still checking it for errors in my spare time, but it is pretty well cleaned up and quite reliable for use as it appears now. Good luck in your searches, and I hope you find the indexes easy and convenient to use. If you need a help file for use with the Email Information Service, just ask.

Kehoe wrote 'Zen and the Art of the Internet' and he is also the archivist for Computer Underground Digest. Apparently the injuries were quite serious, and there was some question in the very early period afterward if he would even survive or not. I guess the doctors are still unwilling to make any commitment regards his recovery other than to say he will be hospitalized for a long time and perhaps permanently disabled. Some parts of his body were badly mangled. Greeting cards and electronic mail messages are being solicited and I refer you to the current issue of Computer Underground Digest for a full report on the incident and how to respond with your notes of sympathy and support. What an awful way to end one year and begin another. My best wishes for Brendan's recovery and eventual return to the net. I imagine all telecom readers agree with my sentiments.

Could someone in Colorado call US West and inquire whether these 579 numbers will be reachable from outside of Colorado? Long-distance carriers are absolutely unwilling to bill surcharges for other than 900 numbers, so the two likely scenarios are either that IXCs don't get surcharged, so out of state callers can call at normal toll rates, or 579 is only reachable from inside the LATA. (In the first case, if you can divert your call to an IXC, a Colorado caller can avoid the surcharge, too.) Either way, sounds pretty brain damaged. I have seen both of these scenarios in different places. Surcharged numbers like 212-540, 617-550, and -976 aren't available from long distance. On the other hand, the number in Chicago which gives reverse D.A. is surcharged if you call it locally but a normal call from elsewhere.

I would definitely have used this in my consulting business if it had been available. It makes it palatable to freely publish your mobile phone number and not have to worry about paying for a lot of calls you don't want. My business clients would have no problem paying for the airtime. I can also imagine that this would make a lot of sense for many other service businesses, like PR agencies and law firms.

Fowler <0003513813@mcimail.com> Subject: Re: Landlines Pay Airtime To Call Some Cellular Phones I've gotten copies of a couple of messages asking whether or not the new 579 prefix (a cellular prefix in Colorado which charges the caller for airtime) could be dialed from outside Colorado. I checked with the number on the U.S. West insert, and the first operator who came on immediately answered "Yes." This seemed a bit suspicious to me (I'm not used to the first person who answers the telephone actually knowing something), so I decided to call AT&T to verify. I went through four operators there, but the best answer I could get was "Probably Yes." So I guess all those COCOT owners out there reading the Digest (yes, both of you) should program their phones not to accept 303-579 or 719-579 for coin calls. Just remember that 579 is a regular prefix most everywhere else. John C.

This was deemed a better functionality choice than allowing blocking to be toggled without any feedback about the final state. (So you can block safely even if you don't know whether the phone was already line-blocked.) In such an emergency your only option is to call the operator and ask them to put your call thru. Incidentally, you can also use the operator as a way of making an anonymous call. US WEST actually suggested this before the Oregon PUC when they were hoping they could use it as an argument to justify with-holding per-line blocking. In an area where no blocking is allowed, although telling an operator to dial for you lacks a certain feeling of privacy.

Calls from the operator always show up as 'outside'. Of course people who reject 'private' most likely will accept 'outside' so I guess your call would get through. And in the case of using the operator to bypass the identification given to the police when you call 911, the rule is the operator is supposed to remain on the line until the police answer and then announce the calling number, as in "... this is the operator, I have an emergency call for the police from the number 123-4567 ..." Some operators do that; some don't, but they are supposed to. No such requirement is in effect for routine calls handled by the operator -- only calls where you dial the operator, state that an emergency exists and ask for the police.

PAT] I would point out that relying on this could be dangerous. Just to give you one example: I have a dialer on my line (which I use to convert touch tones to dial pulses, so I don't have to pay GTE $2.00 per month to accept my touch tones directly), and when Caller ID is offered here, it will be a trivial matter for me to program the dialer to prepend 1167 to all outgoing calls (and there are "standalone" units that do the same thing for touch tone lines, that are even less expensive than dialers). Now suppose that you are one of those folks who cops an attitude and says "if you don't call me with your number unblocked, you must be some sort of scum, and I'm not going to talk to you!" Now suppose you are my neighbor, and late one night my wife sees a fire starting in your kitchen window, and I'm not home. She tries to call you to wake you up, but gets the "please redial from an unblocked line" recording, and has no idea how to respond to that (and since I'm not home, I can't even look up the programming to disable the blocking for her, although your house might be pretty well gone by the time I figured it out anyway). Sure, she would probably then call 911 and report the fire, but if you or your family are sleeping upstairs, you might just have appreciated getting that first call. If you think that the fire example is farfetched, just consider that there are other situations where you might want folks to reach you ... anything from someone responding to a classified ad you've placed to someone who has found one of your possessions, or your pet, or one of your kids. When they get your "please redial ..." message, they just might figure "why bother, I don't know what the ---- that message means anyway", and take some other action that would be more detrimental to you or those you care about. The problem with "Anonymous Call Rejection" is that the folks who take it assume that if someone wants to reach them, they will know whether the line they are using is blocked, and if it is, how to unblock it. In the case of a blocked line, that assumption would quite possibly be true only for the person who either ordered the per-line blocking, or installed the device to automatically prepend the "*67" or "1167" blocking code (and don't think such devices won't become more common in the future). Even if we assume that person knows how to bypass the blocking (which is quite an assumption to make), it's not realistic to assume that every potential user of that line knows how to unblock it. It's a calculated risk, of course. If you are plagued by nuisance callers now, you may figure it's worth the risk. But "Anonymous Call Rejection" is not the sort of service I'd advise anyone to order unless they are currently having a genuine problem with nuisance callers, to the point that it's really disrupting their lives (or their sanity). By the way, I always get a chuckle out of the folks who say "if you don't want me to know your number, don't call me!" Believe me, if I knew that someone I was contemplating calling felt that way, there's no way I would call them, just because they sound like the sort of paranoid personality I wouldn't want to deal with. But in at least some cases, it would quite likely be their loss. But I can see that there is no way folks are ever going to agree on this issue!

Jeffrey, thanks for the post. My understanding is that although the State's PUC has ruled on Caller ID service, deployment (by local carriers) is being held by a State Supreme Court challenge.

Organization: NETCOM On-line Communication Services (408 241-9760 guest) In article you wrote: > I've got a friend who'll soon be moving to the UK (Durham actually). > She's got a Hayes compatible 9600 baud modem that she would like to > take with her and use there. > Can anyone tell me if she can expect it to work with the British phone > system? Is there a special initialization necessary for the modem? > Do they use the same standard phone jacks as used in the US? Yes, a US 9600bps modem will work in the UK, *provided*: (1) You have a power source for the modem that will take 240V/50Hz instead of 110V/60Hz. If you buy a generic adapter, be sure that it will give the correct output voltage AND amperage for the modem, and make sure that it is the correct type -- AC or DC. (My modem uses 14.5V AC, so don't just assume it's DC.) I very much do NOT recommend using a 240/120 "traveller" adapter with the US modem power supply. (2) You have a phone jack adapter. The jacks used in the UK are different both in shape and in wiring. You need to buy in the US one of those adapters that allows you to put a two-line phone on two single-line phone jacks (available from Radio Schlock or AT&T Phone Center Store, etc.). The cable to connect from the jack to the adapter you can buy in Britain probably more easily than in the US. You **may** also be able to buy a cable that does the necessary pin-switching. (Both types of jacks have six slots for wires, the middle four normally in use. The US jack uses the center pair (wires 3 & 4) for 'line 1'; the UK jack uses the outer pair (wires 2 & 5). (Wires 1 & 6 are not used in either.) If you get a "bog-standard" cable, plug the British end into the phone jack and the US end into the "Both" port of your two-line phone adapter. Run a short US phone cable from the "Line 2" port to your modem. (You can perform the same operations with an adapter for running two single-line phones from a single two-line jack, but you'll need a female-female "in-line adapter" as well, since the "Both" port on this adapter is male.) (3) You don't tell anyone connected with British Telecom, OfTel, etc., that you're doing this, because it's technically illegal unless the modem has been certified as meeting the appropriate BS (British Standard -- no, I'm not joking, although the acronym is sometimes apt). If it has been certified, it will have a large green dot somewhere on the hardware (about 1/2" diameter). (4) If your phone line in the UK is pulse, you may want to add into the setup string the code to set the make/break pattern to UK standard instead of US standard. However, in practice, most phone switches are not sensitive enough to tell the difference between 39/61 and 33/67. The command is AT&P1 for UK, AT&P0 for US. Touch-tone is the same in both. Don't even try to use pulse in Scandinavia or New Zealand. (5) If you use the modem to connect to a low-speed European modem (1200 bps or lower), you may need to include ATB0 to use CCITT instead of Bell standards for these speeds. (ATB1 is the default, Bell/U.S. standard) Again, at 2400 and above, you needn't worry about it. (6) I have seen reports that for dialing the US you can use 010-1-83-area.code-number instead of the usual 010-1-AC-number to force a cable rather than satellite circuit. I don't know if this is true; I've never tried it.

I think many of us already do this to an extent through various news sources we get through on-line services or Internet. The technology is incorporate the other aspects that television has (ie video, sound, etc) is actually coming about as we speak. Personally, I've never liked what comes out of my TV News anyway. They are slow, alarmist, and they always show the need to cut down everything to 40 second blurbs. Right now, harder news is found in the better newspapers (the ones that do more analytical news than fact reporting) or shortwave radio where you can usually get the word out from the mouths of the particular country. If the future is more 40 second blurbs, then there's really no point for much news from these TV-Packages. Mike Fulcrum - That Sassy Sassy Style...

Rather, we are going to see revolutionary (exponential) changes as the convergence of cable tv and telephony progresses. The concept that many RBOC's are working towards is video dialtone. This entails an available, dedicated high-bandwidth connection between a subscriber and a software (programming) source on-demand. Each subscriber will be able to access common (ie-network) programming or custom (on-demand) programming in real-time. The keys to this are: 1) high-bandwidth subscriber loops; 2) ATM broadband switching; and 3)mass-storage programming systems (called video servers). There will be no choice to make as to which of 500 different channels to watch, rather it will be a choice as to what to program on the one available video dialtone line, much as one chooses who to call on the current voice telephone line. ALL SOFTWARE WITH NETWORK ACCESS will be available to the subscriber on demand! The revolutionary concept here is that instead of some programmer in NY or LA deciding what I should watch, it will be me choosing what to watch , whether it is a movie from Paramount's library, episode #121 of Donna Reed, Howard Stern's latest special, or the current ABC network program. The telephone company will merely provide the bandwidth from software provider to the residence, other vendors (and RBOC subsidiaries) will compete for viewership. The value of the service will lie in the diversity of programming available to the customer, much as the value of the current telephone network lies not in the fact that there is a phone in your home, but that there is a phone in every home! If the cable companies think that they can compete with a fixed 500 channel system against on-demand video dialtone, they are doomed to go the way of the dominant telecommunications company in the US of 100 years ago, Western Union, namely technological and competitive obsolescence.

The question is "Can the power company send telephone or radio signals over the power lines?" Never mind for the moment any switching problems -- just consider broadcast for now. (There *is* a proposal that power companies install fiber optic cable to homes to help monitor power usage, and in turn sell the capacity to the phone companies. I am asking something different. I am interested in using the actual power lines themselves. My campus radio station used power lines to send the local FM channel, but I don't know how they did it.) The questions are: 1. What is the cutoff frequency of the power grid? Or better, what is the bandwidth vs. distance curve? This is a basic two wire conductor problem but I don't know things like the skin resistance, etc. 2. How do you mix the frequencies? Is the 60 Hz line the carrier, mixed with the signal? Or can you combine them some other way? Any help is appreciated!! Please pass the problem on if you cannot help.

I found this little excursion quite fascinating, but failed in my quest, save for a few references to Rep. Frank's appearance on NightLine discussing some proposed legislation. Kind readers, please enlighten me as to the details of whatever federal law(s) may have been passed regarding telemarketing. I'm interested to learn if *all* forms of automated outbound calling are verboten, or if it just applies to "sales" calls. For example, - A club calling members to notify them of a meeting; - A library calling to notify you of an overdue book; - An automated survey/questionnaire (for non-commercial purposes); - An announcement of a free community service; - A political party calling with a "please vote today" message; (maybe even "Press 1 if you need transportation to the polls") All these seem to be legitimate uses of automated outbound calling, since they either provide useful information/services or offer a significant labor and time savings to a caller who has no profit motive. I welcome private or public replies on this matter. Bob Rankin (r3@vnet.ibm.com) [TELECOM Digest Editor's Note: All the above examples you cite are exempt from the federal regulations. Political calls (vote today) are considered freedom of speech. The library (return our book) has a pre-existing relationship with you as does the club calling to notify you about a meeting. Announcements about free community services also come under freedom of speech. The only calls which are really regulated are those from commercial organizations with whom you have no previous business relationship. They have to follow regulations pertaining to how they call you (using automated techniques or not, etc). The others want to maintain your goodwill, so they follow the same guidelines for the most part, but are not absolutely required to follow them. PAT] ------------------------------ From: Charles F. Hofacker Subject: Access Charges if LD Carrier = Telco? Date: Wed, 5 Jan 1994 12:08:06 EST The recent announcement by MCI that they were going to compete in the local loop has made me curious about something. One of the motivations for this announcement was that MCI could then avoid 'access charges' which are I believe are paid by the long distance provider to the local telco. Since my local telco is Sprint (904-386), if I sign up for Sprint long distance also, shouldn't things be cheaper for me? Why should Sprint charge Sprint access charges? Do I have a point here or is there some regulatory reason that my logic fails? I called the Sprint Long Distance 800 number and the sales rep said he had never heard of access charges. Charlie Hofacker chofack@cob.fsu.edu [TELECOM Digest Editor's Note: Probably the 'Sprint' which handles your local loop is not the same branch of 'Sprint' which handles your long distance calls. Additionally, there is no reason why MCI *has* to not charge you the access fee once they get in the local loop business; just that they apparently choose not to. They apparently have chosen to 'do their bookkeeping' differently than Sprint. Under the law, whoever supplies/maintains the wires coming to your home is entitled to be compensated for the use of the wires in long distance calls and apparently Sprint (the division of the company supplying your local service) chooses to be compensated. Maybe MCI's gimmick will be to have slightly higher long distance rates in exchange for no local-loop charge. It all comes out the same in the end, or nearly so.

Organization: Capital Area Central Texas UNIX Society, Austin, Tx Date: Wed, 5 Jan 1994 17:12:26 GMT I was curious what is available from telephone services or just products on the market that would allow for a single phone number that a customer can dial and be able to connect to one of three separately located offices. Some thing like a support center, call one number and connect to the office/extension or the first available office/extension. Also could this be done with an 800 number as well? All ideas would be appreciated. I'd like to be informed before I talk to the AT&T and MCIs of the world. Thanks, joe ortiz@cactus.org [TELECOM Digest Editors's Note: Well it can most definitly be arranged with 800 service. Your 800 number would terminate different places depending on the place where the call originated. You can also have one of the regional offices be the central answering point and forward the calls one by one to the two other offices manually, then have call- forwarding on the line for after-hours connection to the other two offices. The thing is, how convenient would this be for your customers? At least two of the three regional offices would have to receive calls from *their* customers over a long distance number if all three offices used the same number (which could only be 'local service' to one of the three offices.) If you really want to pay for all the incoming calls from your customers, complainers, deadbeats and anyone else who calls the company, then go with a single 800 number which is routed on a time-of-day/day-of-week/location of call orgination basis, but I don't think you will find it terribly cost-effective. I'd say go with three 'local' numbers for each of the three offices, and internal tie-lines which allowed the receptionist/operator handling incoming calls to manually pass the call to one of the other offices if that was desired.

PAT] ------------------------------ From: aparikh@magnus.acs.ohio-state.edu (Mr. Ashish Parikh ) Subject: Quick Question About Caller ID Date: 5 Jan 1994 04:35:09 GMT Organization: The Ohio State University I am under the impression that only listed (in phonebooks) numbers get identified in one's Caller-ID system. what I mean is that for example my number is unlisted and I call a person with Caller-ID -- according to my views, my number doesn't get recognized by his/her system. My question to you intelligent/experienced folks: Is that true? Could you please briefly describe how the whole Caller-ID thing works. Thanks very much. [TELECOM Digest Editor's Note: Your views are quite seriously mistaken. CID depends on a few things, but having an unlisted or non-pub number is not one of them. First, both telephone exchanges -- that of the caller and the called party -- have to be equipped for the service. If the receiving office is equipped but the sending office is not, then sub- scribers to Caller-ID in the receiving office will get the message 'out of area' on their display when the sending office passes a call. If the sending office is equipped but the receiving office is not, then it all becomes a moot point. Now let us assume both telephone exchanges, that of caller and called party are equipped to handle Caller-ID. The calling party's ID will *always* be passed to the exchange serving the called party. Whether or not the called exchange passes the information on to the called party depends on two things: one, is the called party a subscriber to the Caller-ID service and two, did the calling party not explicitly refuse the passing of the information. By that I mean, did the calling party prepend a special code to his dialing string (typically *67) to tell *his* phone exchange to deny the information to the called party. So if both exchanges are equipped for the service and the called party subscribes to the service, he *will* get your number unless you have specifically told your exchange (to tell the other exchange) to not pass that information along. In the event you request that the inform- ation not be passed along, then the called party will receive a message on his display screen saying 'Private'. Note the difference: the display will say 'private' when the sender denies the receiver the right to the information and the display will say 'out of area' when the receiving exchange is unable (as opposed to not permitted) to supply the information. How you have your phone listed with directory assistance (or not) has no bearing on this at all. All your non-pub listing gets you is the inability of a third person to match your name with a number through the directory and/or the inability to match your number with a name/address through a cross-reference (or 'criss-cross' as they are usually called) directory. So the called party will get your *number* via Caller-ID (unless you specifically block delivery using *67), but it still remains relatively meaningless without a name/address to go with it. Note also that 'automatic call return' where that service exists is not affected by the 'private' status of Caller-ID (calls can still be returned although the return-caller will not know the number being called) and the ability to block Caller-ID via *67 is disabled when calling 911 or *any* telephone company facility or operator. In other words, you can never refuse the telephone company the right to know your number, nor can you hide from the police, etc. Likewise, your number is always known (or soon ascertained) by subscribers to toll- free 800 numbers that you may dial. You can't block that either.

I bought a new VCR for my folks in Lakeland, FL, to make it easy for them to set up the VCR for recording, but the VCR Plus+ codes aren't listed in their newspaper. I'd like to be able to set up a programmable calculator so that it would generate the code for them.

I want to suggest that this topic has been very thoroughly covered in past issues of the TELECOM Digest. I did a search on TDD several weeks ago and found that there have been numerous requests on the topic and some excellent answers over the years. There are issues with Baudot to ASCII conversion with SHIFT characters as well as the hardware issues with half duplex communication which is no tone between characters and 1400/1800 Hz tones unlike any normal modem used today. Also, the baud rate is 45.5 bps. You can purchase dual-mode TDD machines that handle Baudot and ASCII but for some reason they have never really taken off in the deaf community. They tend to be the high end (read expensive) TDD's and are very much overkill for those only interested in TDD communications. Also, the ASCII capabilities usually provided are 300 baud ... insufficient to be useful for much else. There seems to be some lawmaker intervention in this area. Some software was written by John W. Spalding that can be used to emulate TDD on a TRS-80 Color Computer or an IBM PC/PCjr using the cassette port and a modified telephone amplifier. It is well worth getting if only for the comments in the code to help you understand how TDD works. I downloaded it from the HEX BBS (301) 593-7357. It is called tdd56.zip. I am interested in extending the concept of tdd56 and building a simple hardware interface to either use an XT/AT serial port or a simple adapter card. I have some concepts in mind but would be very happy to receive ideas (or encouragement) from anyone.

Apologies if this overlaps a thread I > missed, but anyone in Seattle with info? I have cellular accounts with both of the Seattle carriers: US West Cellular and Cellular One. At least when calling 800 numbers, the US West Cellular system will report my actual cellular number as the ANI, whereas Cellular One reports a non-dialable number that's common on all subscribers. Since 911 systems are often implemented using operator-service trunks, I would imagine that the 'correct ANI' feature of the US West system would also work with 911, although I don't have any specific knowledge that this is the case. As far as Cellular One goes, they could implement 911 ANI with some sort of special data line to the PSAP, without converting to full ANI for all outbound calls. One benefit of the US West Cellular ANI situation is that it allows me to select any IXC that's generally available via Equal Access as my default carrier for the cellular phone.

There are basically three standards -- AMPS used in North America, JSM (?) used in Japan, and GSM used in the rest of the world. It's the same with TV-sets. In Europe we have PAL and SECAM, in the U.S. they have NTSC; don't know about the rest of the world. As I see it, this is a producer-pushed scenario that we will have to live with. The reason is that the producers will be able to sell more terminal-units -- those who need to be accessable in all three areas will have to buy three units instead of one.

There are at least two companies working on a satellite based system for digital mobile communication that is to be working worldwide.

The frequencies and access methods (GSM is TDMA/GMSK each channel is 200 KHz, ADC is TDMA/QPSK channels ea 30 KHz, CDMA is DS-CDMA ea channel 1.25 MHz) are completely incompatible.

This is not a trivial question; my response is always to put the tools out there so that individuals can make the choices for themselves, as I figure that the question is difficult enough that I shouldn't be answering it for someone else. To take the fire example of this thread: [The situation was a neighbor noticing a house fire, and attempting to call, but getting rejected because of anonymous call rejection.] If the neighbor's front door was unlocked, then people could run in and wake everyone up, or put out the fire. But leaving the door unlocked is a risk. Do people have little glass boxes with 'Pull for emergency access' on their doors, so that anyone can get in if necessary? No, because that would defeat the purpose of the lock on the door. But people do give keys to neighbors, because the additional risk is offset by the enhanced safety of having another set of (trusted) eyes able to look out for you. I tend to turn off the ringer of my phone when I want to sleep. That way people can call me at any time without worrying about disturbing me. However, if there was an emergency when I was in bed, my phone would be worse than useless. I doubt that I would ever get anonymous call rejection; my only need to know who is calling is for convenience. But I say 'Let it be an option, allow people to choose the risk.'

This distinction is between a number not being available and being blocked. That is, the calling party number may not be available for inter-LATA calls, and in my opinion, these calls should not be rejected. This is quite different than if the delivery of a number has been blocked (i.e. *67), which is when calls should be rejected by this service. If the service is worth anything, it would make this distiction. ISUP carries the calling party number and address presentation restriction information (see TR-246 T1.113.3 3.7). Hence, the service could reject calls where calling party number delivery has been blocked and allow calls when the number is not available.

Actually, Radio Shack sells an RJ11 adaptor that splits out the 1st and second line for you. It looks like a normal one phone jack to two phone jack adaptor, except it has three jacks. One for line one, one for line two and one for both lines. There is no need to do the extra wiring. On a side note, I recently called NY Telephone (or NYNEX as they want to be called now) about getting a second phone line installed in my apartment. I was shocked to get a quote of $185 for the second line (first line costs about $60). This is the price for installing a totally different phone line in the apartment. I complained a little that they didn't need to do that as there was a perfectly good second pair coming into the apartment I didn't get very far as the customer service rep wasn't technical. Is there really any need to get a totally seperate line into my apartment? Diamond State Telephone (Delaware) was able to put a second line on the second pair. Is NYNEX just trying to gouge me?

Telco outside plant records are in notoriously bad condition in some places. The rep may have actually not had any record of the second pair in your apartment or may have had a record of it but shown it to be actually a multiple of someone else's first pair or what-have-you. Have you tested that pair to see if it is alive (with someone else's service because some installer in the past never opened it up at the pole) or if it is in good condition? Have you traced it back to the demarc, such as in the basement of the building where you live? If you can get that second pair back as far as the demarc for the building (or yourself, whichever applies), then you have a second pair and it should not be required for telco to make any visit to your home with the high cost for same. You have to be careful though; make sure that set of wires you are looking at actually goes somewhere and reaches the demarc. If not, then you are possibly stuck for the high installation costs of a second line. You should trace that pair first, getting it back to the demarc if at all possible. Note on the demarc there may be some notations (little tags tied on with bits of string are common) telling the installers what goes where. If you see a notation saying something like 'cable 74, pair 29' or similar then when you call back to the business office if you get the same rap about how a new line has to be installed in your apartment tell the rep you *think* 'cable 74 pair 29' is there already. Note I emphasize 'think'. You're not a phone installer so don't try to act like one. But stress you have seen complete wires back to the demarc which appear to be idle, and you are wondering if the rep will please have someone confirm or correct the outside plant records.

Adopting the American practice of not including country code at all is simply not applicable outside North America. > In Europe 0 is being now used as prefix for area code > numbers and 00 as prefix for country codes. Not at all true, as a general rule. Here in Norway, we currently use 095 1 xxx... to dial North American numbers. Up until last year, a (single) leading 0 generally indicated "not a local, ordinary phone no" but anything else, like long distance (0 + area code), out-of-country (0 95 + country code + national no), directory service (0 180 Nordic countries, 0 181 International), weather forecast, news summary, error reports for the phone system etc.etc.etc. But during 1993, area codes have been removed; you can now in principle move all across the country keeping your old number ("for administrative reasons" they will currently give you a new number, but they admit that one of the reasons for dropping area codes was to open up this possibility from a technical point of view), and the leading zero has been removed from all special services. (There were three special emergency numbers which did have double leading zeros, for Fire alarm, Ambulance and Police respectively; they now have a single leading zero). So it all boils down to 0 being a perfectly ordinary digit, even as a leading one, in the Norwegian national numbering plan. > But then some French idiots come up with a stupid numbering system > (for Paris *and* Greater Paris +331 xxxxxxxx rest of the country +33 > xxxxxxxx ). According to my phone book, France is 33. Then, if the first digit is 1, then it is Paris, if the first digit is something else, it is NOT Paris but some other area. Is that really "stupid"? You could similarly classify it as stupid that any international number starting with +4722 is Oslo, starting with +4772 or +4773 is Trondheim, and the est of the country is +47 and not +4722, +4772 or +4773. But we see it differently -- the first digits after the country code indicate which city. Plain and simple: There are always eight digits, the leading ones hinting about the location. (Until they open up for taking your phone number along when you move to another city.) ------------------------------ End of TELECOM Digest V14 #9 **************************** Received: from delta.eecs.nwu.edu by MINTAKA.LCS.MIT.EDU id aa05969; 5 Jan 94 22:13 EST Received: by delta.eecs.nwu.edu id AA13066 (5.65c/IDA-1.4.4 for telecom-recent@lcs.mit.edu); Wed, 5 Jan 1994 18:33:20 -0600 Received: by delta.eecs.nwu.edu id AA30086 (5.65c/IDA-1.4.4 for /usr/lib/sendmail -oQ/var/spool/mqueue.big -odi -oi -ftelecom-request telecomlist-outbound); Wed, 5 Jan 1994 18:33:03 -0600 Date: Wed, 5 Jan 1994 18:33:03 -0600 From: TELECOM Moderator Message-Id: <199401060033.AA30086@delta.eecs.nwu.edu> To: telecom@eecs.nwu.edu Subject: TELECOM Digest V14 #10 TELECOM Digest Wed, 5 Jan 94 18:33:00 CST Volume 14 : Issue 10 Inside This Issue: Editor: Patrick A.

Well, Mike, I am old enough to remember all the fancy claims that 'cable-tv' would put over-the-air tv out of business, would make networks obsolete, would transform our very lives, would offer first-run movies, would offer live video from foreign countries, would bring the classroom to the living room, would offer access to niche programming, fine arts, etc etc etc. What we wound up with is re-run mills, home shopping channels, music videos, 24 hour weather channels, preachers, pay-per-view wrestling and more commercials than ever. Even the so-called premium services like HBO are lame and repetitive. So before I go GA-GA over this new network idea, I gotta see the plans. If the tele-entertainment industry's history of 'promising heaven and delivering re-runs' is any indication, we will have 500 channels of on-demand QVC and pay-per-view wrestling. > Personal Opinions Only Same here.

As I've posted before, they certainly are! Whatever the solution to the 1+ problem, it sure would be nice if *something* worked everywhere. Even if other techniques were local option. Maybe a new prefix, 111+ NPA+7D, which could be used *anywhere*, for either local or LD calls, same NPA or different. Perhaps the third 1 (or whatever) could be considered a country code, so that whatever scheme is adopted will eventually work world-wide. The 1+ problem seems like a NANP problem now, but will certainly be a world problem soon.

During the time they lived there, the dialing requirements not only varied due to area code and "localness", but also by whether the "other" phone company was involved. I don't remember the particulars, but dialing a local SWB-SWB call was different than dialing a local SWB-GTE call. As I recall, you needed at least ten, if not eleven digits, to call a GTE 214xxxxxxx number from a SWB 214xxxxxxx number, even if the call was to the next exchange (or next house...). One major annoyance was the percentage of calls into GTE that went high-and-dry. Has any of this changed recently?

AT&T announced today that a comprehensive library of linkable code modules, including RSA security technology and the NIST Digital Signature Algorithm, is available for licensing. Linkable code is available in the form of linkable object module libraries and Windows Dynamic Link Libraries (DLLs), which are under license from Information Security Corporation of Deerfield, Illinois. The code is compatible with shrink-wrapped programs recently introduced by AT&T. The security functions included have applications for a broad variety of software, including tax returns and other electronic-forms programs, electronic mail, electronic data interchange and electronic fund transfers. "Electronic commerce has an inherent requirement for privacy, data integrity, authentication and non-repudiation," said Larry Salter, director of secure systems and services for AT&T Secure Communications Systems. "These capabilities are ideal for PCMCIA and smart-card applications as well as conventional software for PCs and workstations." The package includes code for DES encryption, the ElGamal public key cryptosystem, the Digital Signature Algorithm, the Secure Hash Standard and most RSA security functions, including RSA encryption, key management and digital signatures; MD5 hashing functions; and the Diffie-Hellman key exchange protocol. A proprietary encryption algorithm for exportable applications is available as well. More than a dozen military and civilian federal agencies and a growing number of corporations have already licensed the code for new software applications, Salter said. "This is a full range of information security functions, relying on the most widely accepted government and commercial standards," Salter said. Prices for code packages containing DSA technology are $750 for the DOS/Windows version, $1,000 for the Macintosh version and $1250 for the UNIX version. For code packages containing RSA technology are $300 for the DOS/Windows version, $400 for the Macintosh version and $500 for the UNIX version. The license allows developers to load the code into two workstations for software development. Royalty payments are required for distribution of applications to end users. AT&T and ISC have incorporated the code modules into software that provides a wide range of security capabilities. AT&T SecretAgent (R) Software provides DES encryption, ElGamal key management and DSA digital signature technology. AT&T SecretAgent (R) II Software provides DES encryption, RSA digital signatures and key management, and MD5 for message digests. AT&T Surity (TM) DSA Signature Software is a digital signature program. And AT&T SecureZMODEM (R) provides DES encryption and user-transparent key management for data communications using the ZMODEM protocol. Programs using RSA technology are in development. Software developers can get more information on licensing the AT&T linkable code module library by calling the AT&T Secure Communications Customer Service Center, 1 800 203-5563. ------------------------------ From: toddi@ocsg.com (Todd Inch) Subject: Notice to Antique Phone Buyers Date: Wed, 5 Jan 94 12:54:43 PST I finally checked out an old phone that has been in a locked case at the local thrift store for months and wonder if any collectors out there want me to buy it for them, or buy my old Monophone, for that matter. It's shaped like an old Monophone, but has an all-brass base and a swivel-up handle apparently for carrying it. The handset is bakelight and the handset cord is cloth covered. RTT56 is stamped on the underside and I believe RTT is in a logo on the dial. It also has a white button in front of the dial on the front. It's priced at $79.99, which is surprisingly expensive for a thrift store where I occasionally get "real" (e.g. WECO, ITT, Stromberg, etc) touch-tone phones for $5 or so.

Unfortunately, this is not in accordance with the specifications laid out in many countries. A Q.23 receiver must typically be able to reliably detect as little as 40 ms at up to -28 dBm. In the case of a voice mail system, the level requirements are even more stringent (-43 dBm). In some countries, these tests are performed while dial tone at e.g. -7 dBm is also present on the line. Elsewhere, (I think it's Spain) they even superimpose a voice signal at some ludicrously high level (-2 dBm or something). In my opinion, the level requirements are unrealistic in many cases. Requiring a Q.23 receiver to detect a tone at -43dBm means that the network is allowed to attenuate by some 36 dB, given the fact that DTMF tones must be transmitted at -7 dBm.

What is SoftModem Technology and what are its benefits? The SoftModem (tm) Technology Story Digicom Systems' exclusive SoftModem Technology has revolutionized modem design using a general-purpose, reprogrammable Digital Signal Processing (DSP) chip. This neat software solution allows you to take advantage of on-board RAM-based modem/DSP memory. The SoftModem approach allows operational algorithms to be easily installed, quickly changed, and most importantly, upgraded via software. Designed using upgradeable hardware architecture, SoftModem Technology provides the flexibility necessary to keep up with evolving communications standards and changing command interfaces. In addition, this design improves support and service and facilitates the integration of data, fax, and voice-related applications. SoftModem Technology provides all the standard features and characteristics of a high-speed, high-performance modem as a hardware programmable solution that can be modified or enhanced and then distributed over the telephone line, computer networks or on a diskette. Based on SoftModem Technology Upgrade modem features without changing the hardware. That means you can keep up with changing standards and save money. Just install new software to get more out of your modem! FREE ROM updates such as V.32bis (14,400 bps), V.42bis and MNP5 (data compression) can be downloaded. Feature upgrades like Send/Receive V.17 Fax (14,400 bps) and V.32terbo (19,200 bps) will be available from your local computer reseller or online distributors. The Connection 144+ is the world's first software upgradeable modem. It's based on SoftModem Technology, which reduces the risk of obsolescence that is always a problem with traditional modems. Protect your modem investment - the Connection 14.4+ will serve your needs for years to come. 3. What's so special about Digicom? Some background on Digicom: Digicom Systems, Inc. was one of the first to realize the power and flexibility of digital signal processing solutions in data communications (in 1987). DSI then emerged as a leader in modem DSP design which allowed them the flexibility to introduce the first V.32 modem using just one, albeit very powerful DSP. Digicom introduced the industry's first V.32bis modem to market, the first V.32bis modem with send and receive fax capability and very recently the first modem based on SoftModem Technology. A local Silicon Valley manufacturer. 4. Can you explain Signal Computing Architecture? Digicom's products are based on Analog Devices general purpose digital signal processors, abbreviated DSP. Modem algorithms require powerful computational resources and DSPs are well suited to meet them cost effectively. Analog Devices has introduced a common architecture for its DSPs and the accompanying peripheral chips. It is called the Signal Computing Architecture. The advantages of this approach are manifold. Companies developing in different areas of digital signal processing like voice, data communications, graphics can join efforts more easily and offer a more unified interface to application program developers. The Signal Computing Architecture is indeed very popular at present and is attracting more and more developers, like AOX, Cardinal, Dialogic, Hewlett Packard, Media Vision, Spectron and many others. For interested readers BYTE magazine's four article series on Signal Computing may be a good start (November 1992). The Signal Computing Architecture is emerging as a cost effective albeit powerful and versatile platform for communications and multimedia applications. 5. Are there Digicom related ftp sites? feenix.metronet.com /pub/wolfgang SoftModem related files. The subdirectory /smodem carries the latest production algorithms and open beta files. Drivers for Linux and OS/2 are available here. ftp.netcom.com /pub/wolfgang General information files, like this file Digicom.FAQ. ftp.rahul.net /pub/wolfgang Scout+ modem files sgi.com /sgi/fax FlexFAX Unix fax software and fax related documents and information. 6. What is the recommended setup for PCs, Macs and Suns? Here are a few simple setup strings for three different operating systems which work well for the author. They should work with the Digicom Scout+ as well as Digicom 9624 series of modems. For the Connection 14.4+ modems AT&F&W1 should work fine in most cases.

It's datecoded: 3225 e.g. translates into 1993 February 25. 9. Are there any reviews available? There are numerous modem reviews in which Digicom modems are usually fairing quite well. Here is only a brief selection. PC Computing Magazine rated the Digicom Scout+ as the top choice from the 48 modem reviewed in the June 1993 issue. Modems were rated for price/performance. ftp.netcom.com /pub/wolfgang/Scout.txt has a review of the Scout+ by the author of these frequently asked questions. sgi.com /sgi/fax/bakeoff carries extensive test results on the fax capabilities of several current modems and rates them according to a metric called faxstones. The test was performed by Sam Leffler. The Scout+ faired well. PC Week reviewed the Digicom 9624LE+ favorably in its November 19, 1990 issue. PCWeek published benchmark results on April 29, 1991. The 9624LE+ was selected as the Analysts' choice. The fractional FT1 CSU/DSU received the 1993 user choice award in Communications News. Digicom is supplying modems and chipsets to several other modem manufacturers under OEM aggreements. 10. Where can I purchase Digicom modems?

He sustained massive head injuries, but on Monday, the prognosis for his survival was "cautiously optimistic," according to his brother. Tragically, the severity of the injuries will likely produce permanent disability, although the nature and extent remains uncertain at this time. Doctors expect that he will be semi-comatose for at least two weeks. The hospital is not allowing him to receive flowers or other tangibles. Cards may be sent to him at: Brendan Kehoe c/o Alice Kehoe Penn Tower Hotel Civic Center Blvd ad 34th Street Philadelphia, PA 19104 Brendan will not be able to directly communicate for some time. But, his brother and a few friends intend to set up a net-link to keep people informed of his condition. ------------------------------ Date: Wed, 05 Jan 94 18:52 CST From: Jim Thomas (tk0jut1@mvs.cso.niu.edu) Subject: How to Send Your Thoughts to Brendan Kehoe As Pat noted in a previous issue of TELECOM Digest, Brendan Kehoe was seriously injured in a car crash on 31 December. Brendan's wit and helpfulness earned him many friends. The Cu Digest editors are encouraging netfolk to send electronic messages to him that include a joke, funny story, or a "get-well" recipe. The editors will accept e-mail contributions until about January 19. Then, we'll print the responses on rag-bond paper, bind them, and send them to him as a "net anthology." Send notes to: tk0jut2@mvs.cso.niu.edu with the subject header: TO BRENDAN Jim Thomas / Gordon Meyer CuD Editors [TELECOM Digest Editor's Note: I hope all readers of this Digest who are familiar with Brendan Kehoe will take a few minutes sometime in the next week or so to send their thoughts to Jim and Gordon per the examples above.

For those readers who are not familiar with Computer Underground Digest, now is a good time to tell you about it. It began back in 1990 as an overflow mailing list for a series of messages here in TELECOM Digest dealing with hacking and phreaking, and some persons who had been arrested and put on trial for related things. The messages just kept rolling in and CuD stayed around to become -- like this Digest -- a very popular, very well-read e-journal on the computer networks of the world. CuD should definitly be on your 'must read' list of e-journals and if you would like to subscribe I'm sure you'll enjoy it as much as I do.

As the Digest Editor noted, with very few exceptions, if you can call an 800 number, the recipient can get your ANI. I manage a switch which has hundreds of 800 numbers going to it (about five of them for my personal use), and I can assure you that I have no problems at all getting ANI from California. In fact, only about .5 percent of all calls nationwide arrive with no ANI, and California is no exception. Since my switch is not located in California, all calls that come to it from the Golden State are interstate commerce, and any laws that the state may have do not apply to them (BTW, there are no laws regarding ANI in CA that I am aware of anyway). I even have a couple of customers in CA that receive ANI delivery from me, either in real-time via inband DTMF, through voice mail and pager mail, and of course on their bills (just like any 800 service today). Perhaps the state may have something to say about that in the future if they choose to do so, but they have not chosen to do so up to now. Also, it is questionable as to what would happen at that point anyway, since the calls would still cross the state line before returning to California (and no, this is not done to get around CA's [nonexistant] ANI regulation - it just so happens that I don't live in CA anymore). And there is blocking available -- if callers choose not to have me or my customers pay for their telephone calls (which is what they are doing when they call an 800 number), we will never get their number. I guess this is a form of per-call blocking :-) (I suppose you could even have per-line 800 ANI blocking if you got a toll restrictor and programmed it to block 800 numbers :-)) Steve Forrette, stevef@wrq.com ------------------------------ From: co057@cleveland.Freenet.Edu (Steven H.

PAT] In some states the steps the moderator describes are exactly right. In New York, things are a little different. Telco is obligated to provide a network interface jack (if that is what you want) *in your apartment*, for a price that is fixed -- unaffected by how long it takes to do. This is the case regardless of whether their records show a previous second line in your apartment; all that changes is the amount of the fixed price. Last I checked the cost for your situation (where they claim there was never a second line) is $88. Then you just connect your own wiring to that second NIJ.

Dale <0005517538@mcimail.com> Subject: MCI's ATM Communications Response SUBJECT ARTICLE: Setting the record straight on the Communications Week article "User's Want Data Details for MCI" (12/20/93) DATE: January 4, 1993 On December 20, 1993, Communications Week published a front-page article entitled "Users Want Data Details From MCI". This article criticized MCI for not publicly disclosing detailed plans for ATM service offerings. Customers may ask about the article and MCI's overall strategic data direction related to emerging technologies such as ATM. Communications Week extensively quoted Paul Weichselbaum, MCI's vice president of data marketing, along with many telecommunications managers from a variety of companies. Mr. Weichselbaum has written to Communications Week regarding their news coverage. His letter to the editor seeks to place his comments in the appropriate context and accurately explain MCI's approach to ATM. The complete text of the Communications Week article and MCI's response is included below. The article began by stating MCI "will renege on a promise to detail its ATM plans by year's end, frustrating users who are trying to understand the carrier's data strategy". The article continued to criticize our lack of an ATM switch vendor and the lack of service and pricing details. It is important that MCI assist customers in placing emerging technologies in the proper perspective. Switched Multimegabit Data Service (SMDS) and Asynchronous Transfer Mode (ATM) are two emerging technologies that will play an important role in the next generation of data service offerings from MCI. ATM employs fixed-length cells to carry data, voice, and video at speeds suitable for wide area connections. This technology has the potential to support new applications and consolidate traffic. ATM will obviate the need, at least technically, for the multiple separate networks (such as data, voice, and video-conference) most companies maintain. This technology could allow corporations to build a single enterprise wide area network carrying all their communications traffic. For better or worse, ATM is often looked upon as a networking panacea. The reality is that ATM is one of several solutions that may or may not be appropriate for a customer at this time or in the near future. The following are key points to remember when discussing MCI's view of ATM technology: MCI believes ATM, in its current state, is more of a technology than a service; MCI has found that most of our customer's current application can be served with existing data services. ATM's full potential and value will be realized through the implementation of future applications; ATM technology must mature; standards must be developed and finalized. The technology is quickly maturing; product and hardware life cycles are short. The first generation switches are not adequate to offer a robust central office based service offering. MCI continues to actively work with switch vendors to influence second generation technology. As noted above, experience has shown that the vast majority of customer applications do not require transport rates in excess of 1.544 Mbps. ATM is traditionally associated with transport speeds in excess of 45 Mbps. Although potential standards are being evaluated for ATM below 45 Mbps speeds, other issues must be resolved before ATM becomes a truly viable service offering. MCI understands these issues and is working with manufacturers and standards bodies to arrive at solutions that will allow carriers to offer interoperable, network based ATM service offerings. Various trade publications have echoed MCI's concerns. John McQuillan's recent article in Business Communications Review ("Where are the ATM Applications?", pp 12-14, November 1993) noted that "...there are simpler and less expensive alternatives to ATM". He continued to state that "...while the ATM community has been focused on ATM at 45 Mbps rates and up, customers spend most of their money at T1 rates and below". Mr. McQuillan is widely recognized as a leading industry expert on ATM technology. Readers of the Communications Week article may form the impression that MCI is behind everyone else since we have not publicly disclosed specific ATM service plans. MCI has chosen not to tell our ATM story via the media. There are two primary reasons for this. MCI cannot control the media and their spin to a story. In addition, our discussions with vendors and end users impact the formulation of ideas and thinking about what our ATM service directions should be; we want to keep that information away from the competition for the time being. MCI is not at a competitive disadvantage related to the understanding of ATM technology. MCI is actively participating in the ATM Forum and other standards bodies. We actively participate in the development of standards and applications related to ATM. MCI is also investigating current ATM research and technical design issues. We have implemented a trial ATM network to study ATM. Our trial network has allowed the engineering lab to study flow control interactions between higher layer protocols and ATM switches. We have also found that the high speed access lines and bursty nature of today's high performance applications such as file transfer and distributed database applications can easily overrun small buffers that are often found in ATM switches. These detailed simulations have allowed us to understand the impact of existing buffer management schemes on TCP flow control mechanics and the resulting useful throughput that can be achieved. Although MCI has not announced an ATM switch vendor, switches from leading ATM vendors have undergone evaluation in MCI's Network Engineering Laboratory. Testing continues on second generation switches. We have found that ATM technology is quickly maturing and switch hardware life cycles are short. To further the development of ATM, MCI has provided feedback to ATM switch manufacturers on the key issues we have learned. Our methodical approach will allow us to influence the technology changes in the next generation of switches. This approach will ultimately be advantageous to our customers. More than a dozen ATM products have been announced in 1993 - and more will be available in 1994. Hardware vendors interested in ATM technologies include Cabletron, Cisco Systems, Motorola Codex, Newbridge, Northern Telecom, StrataCom, and Wellfleet to name a few. At the present time, most switch vendors only provide a partial set of service characteristics associated with ATM (e.g. access classes and the timing, bit rate and connection mode attributes, etc.). Industry analysts generally agree with MCI's view that ATM standards must be further developed to address additional areas of concern to a perspective end user such as the lack of flow control between switches, no LAN bridging specifications, and a lack of quality of service definition. In addition, many service features offered by vendors are proprietary in nature. Only when these issues are addressed, will the full potential of ATM be realized. Once again, other industry analysts and periodicals mirror MCI viewpoint. For instance, an article in Data Communications magazine ("ATM at Your Service?", pp 85-88, November 1993) noted that "without standard service definitions, carriers may end up developing their own approaches, a scenario that could lead to the same troubles that have plagued ISDN: lack of interoperability and spotty geographic coverage." The press and general public is often unaware of the work MCI has undertaken with ATM. Our focus is on driving service related issues with standards bodies and vendors; not to engage in public debates, create unfulfilled service expectations, pre-announce products, or provide proprietary service solutions in the absence of industry standards. The above is not meant to provide you with all the details on MCI's strategic data direction or our work with ATM. It is meant to inform you that MCI is actively undertaking initiatives to develop expertise with the technology. MCI's pragmatic approach will allow us to effectively develop, market and support the existing and emerging services required by our customers. These considerations will ultimately prove to be in the customers' best interest. COMMUNICATIONS WEEK ARTICLE: Communications Week via First! : WASHINGTON MCI Communications Corp. will renege on a promise to detail its ATM service plans by year's end, frustrating users who are trying to understand the carrier's data strategy. "I just wish I knew what its data strategy is," said Thomas O'Toole, director of communications systems for Westinghouse Electric Corp., Pittsburgh. "MCI always, for some reason, has struggled with a data strategy." In briefings delivered several times during the year, MCI has glossed over its plans to offer asynchronous transfer mode services. MCI officials have said the company will provide ATM services, but they have given no details on prices, operating speeds, network management capabilities, switching platform or classes of service. That kind of information is already available from AT&T, Sprint and WilTel-MCI's main competitors. "We clearly have a different approach," said Paul Weichselbaum, MCI's vice president of data marketing. In May, Weichselbaum said that by the end of this year, MCI would select an ATM switch vendor, begin field trials and provide service details (Communications Week, May 31). It is clear that MCI will not meet those goals. MCI now expects to select its ATM switch vendor during the first half of next year and roll out a service late next year, Weichselbaum said in an interview with Communications Week. He would not discuss service characteristics or say when such information would be available. Weichselbaum explained the delay by saying that MCI has tested ATM switches, but found that they did not measure up to its expectations. SMDS Late Too MCI also has vacillated on its plans to offer a switched multimegabit data service, which it announced in October 1992 for general availability in mid-1993. During the May briefing, Weichselbaum said MCI was postponing SMDS availability because of software delays. MCI canceled an SMDS beta test that had been planned with Rockwell International Corp., Seal Beach, Calif. MCI was supposed to reschedule the test, but has yet to do so, according to Chuck Ramey, Rockwell's manager of network hardware-telecommunications services. Weichselbaum said this month that SMDS will be generally available in the first half of next year. He said users are trying the service now, but he declined to name them. Users said MCI's failure to provide details on its ATM plans or roll out SMDS indicates that the carrier's data strategy is in disarray. "If they want to be seen as a leader in the industry, they need to provide information on [ATM] pricing and service levels pretty quickly," said Blair Sanders, senior member of the technical staff at Texas Instruments Inc., Dallas. During a recent interview, MCI chairman and CEO Bert Roberts insisted that MCI has a strong data strategy. If there's confusion, he said, MCI may not be doing a good job of communicating its plans. "Sometimes it's a market perception, but in this case, I think it's a real issue," said Rosemary Cochran, principal with Vertical Systems Group, Dedham, Mass. Details, Details The information on data services MCI recently supplied Domino's Pizza in response to a request for proposals was "far less detailed" than that received from AT&T and Sprint, said Daniel Gonos, telecommunications manager at the Ann Arbor, Mich.-based pizza company. "I'm not sure whether it's a learning curve with MCI, or that it's just trying to be careful," Gonos said. "But it's clear, for whatever reason, that MCI is behind everyone else." Jeffrey Marshall, director of communications for Bear, Stearns & Co. Inc., New York, said MCI has done a good job articulating a broad data strategy, but that the details are missing. Other MCI users said they are satisfied with the information they have received from MCI. "I think it's been up-front since the beginning with ATM," said William Johnson, director of communications at Woolworth Corp., New York. "It wanted to make sure it had its act together before implementing a program. I don't think it's at that point yet. We need more details, but we can wait." Donald Moore, communications technology manager at Aldus Corp., a Seattle-based software maker, said ATM is still far enough in the future that his company can wait for details. Moore said, however, that he was told that MCI already has selected its switch vendor but won't publicly disclose its choice. Apparently, confusion over the switch vendor extends to Roberts, who said earlier this month that MCI has selected an ATM switch vendor. MCI representatives later denied that Roberts made that statement. Weichselbaum argued that MCI has a solid data portfolio, and that the carrier has yet to find an application that can't be handled by its existing services. He said ATM is not necessary today because frame-relay, SMDS and other switched data services offer users what they need. MCI tries to encourage companies to consider data services like frame-relay or SMDS, rather than ATM, Weichselbaum said. But MCI will bid on request for proposals in cases where users insist on ATM. "We would have to install switches if the bid were approved," he said. This approach bothers some users, who said they would prefer to use an established network. "We don't mind being a test pilot, but if it's a matter of getting into an airplane that's never been made before, we're a little shy about that," said Marshall of Bear, Stearns. MFS Datanet Inc., Sprint and WilTel already offer ATM-based services. AT&T has detailed its service, which will be available in mid-1994. "There's no compelling application that absolutely requires ATM today," Weichselbaum said. "We don't want to do it because everyone else is doing it." Industry analysts said MCI is too wrapped up in its purchase of BT North America Inc., San Jose, Calif., to focus adequate attention on its data strategy. Roberts confirmed that the company was preoccupied for at least two months working out the details of their joint arrangement. [12-22-93 at 14:59 EST, Copyright 1993, CMP Publications, Inc., File: c1222056.2mp] MCI RESPONSE TO THE COMMUNICATION WEEK ARTICLE: MCI's Paul Wiechselbaum, vice-president data marketing, wrote the following letter to the editors of Communications Week. The letter will probably be published in the 1/10/94 issue. MCI takes great exception to the tone and content of your December 20, 1993 article, "Users Want Data Details From MCI." You quote me as saying "we clearly have a different approach [to ATM]," without giving your readers the opportunity to understand or evaluate that approach. First, MCI approaches ATM not as a high technology company, but rather as a service company; we employ high tech products in the provisioning of our services. We want to offer data services to the marketplace that will help customers compete more effectively. In our opinion, ATM in its current state is more a technology than a service; it's a fast-bit pipe using ATM multiplexing. CommWeek editors seemed to agree with this point, given the November 22, 1993 editorial, "Bridging the Gap of ATM Theory and Reality." Our market research shows that it will be a couple of years before the multimedia promise of ATM can be fully deployed as a broadly available, economically compelling and completely standards-based service. We've found that most of our customers' current applications can be served with existing services. In other words, ATM's full potential is required for future market applications and much less so for current ones. At the same time, our discussions with ATM switch vendors over the past three years have convinced us that the technology is maturing quickly and product life cycles are short. With first generation switch technology only a pale imitation of what ATM could be and the market still immature, we are taking the time to try to influence second generation technological changes to our customers' advantage. We believe we can enter the market with a much richer ATM service well before it gains much momentum and the longer we can wait before making this investment, the more likely it is that a particular vendor of ATM technology will have something better to offer than we've seen to date. Our experience with frame relay reflects the merits of such an approach. While we were among the last to offer a commercial frame relay service, the fact that our HyperStream Frame Relay continues to be unique in the marketplace a full 18 months after introduction -- with its sustained burst capabilities, usage and mileage sensitive pricing, and asymmetrical provisioning -- is telling. Such capabilities give our customers greater control and ultimately, save money over competitive offerings. HyperStream's success has convinced us that our market strategy is on target. Given this experience, we don't feel compelled to mimic other carriers in the ATM arena; our focus is on the market. Your broad generalization that "users want data details from MCI" is misleading. CommWeek knows very well that MCI's data strategy is much broader than just ATM. And we are certainly telling customers what our ATM directions are and how these fit with our overall data plans. However, to date we've chosen to do this in private customer briefings. These briefings serve to validate our current conclusions on ATM services while enabling us to protect competitive advantages we gain as a result of those discussions. MCI clearly does have a different approach to ATM. We believe it's a methodical, realistic, customer-oriented and responsible one. It reflects the market window available to us as well as the technology cycles we're seeing and shaping. The feedback from our customers has been both positive and constructive. It's unfortunate that our rationale for pursuing this different strategy was not fully represented in the story. Paul J. Weichselbaum Vice President Data Marketing ------------------------------ Date: Thu, 6 Jan 1994 01:00:49 EST From: Paul Robinson Reply-To: Paul Robinson Subject: A Tale of Two Dialtones Organization: Tansin A. Darcos & Company, Silver Spring, MD USA It was the best of dials, it was the worst of dials ... I originally had four phone lines coming into my house. The family member who needed the fourth line didn't need it any longer, so I had it shut off. Recently, another relative had to move in with us and wanted their own phone line. Since I had a circuit left I called the phone company to have them turn that on ($47.00) from the office instead of their paying another $65.00 to have another circuit installed (when the new wire was installed, the old wire, which the installer discovered was spliced, was pulled and replaced with a six-pair cable; see "Dial Tone is No Extra Charge" printed last year.) I do my own wiring so I had put in the wire and turn on was scheduled for the 5th. Earlier in the day I had made a call from my computer line. I went to work and called home to check up on my mother who is recovering from Cancer. The phone doesn't answer. This is unusual. Over several hours I tried it, off and on, and got no answer. Tried calling the special number in the hall (it's used for my 800 number) no answer. I was worried a little, so when I got home I discovered nothing unusual. I picked up the phone and got dial tone. I did, however, discover later that the hall phone / answering machine's power had become unplugged, which meant it wouldn't even allow me to dial out. Plugged back in it gave me dial tone. Note this is the electrical plug, in addition to the telephone line. I went down to the basement demarc and finished wiring the new phone line. No problem and I get a dial tone. I dialed my home number and it was busy. Dialed the special number that runs to the hall phone and it just rang (as stated above). I must have, in running the 50 or so feet of wire down to the basement, miswired the phone onto my line. But since each circuit goes through its own gas fuse, I thought I had done it correctly. I left the phone on a busy signal and went to the other phone. Dial tone. All I did was hook up the new phone. This doesn't make sense. Then it hit me. I hung up the new phone, went back to the regular phone, and dialed the regular number. The new phone rang. Went upstairs, got the paper with the new phone number C&P supplied me when I placed the order. Dialed that number and my old phone rang! I never touched my original connection, so the problem is with the phone company. This is what happened: in ordering the new service, the phone company put the new service on the original number, and put our old service on the new line! Well, tomorrow morning I'll call and make a stink about it. There are at least six or more outlets running wires into the original connection for me to change them all, so I'll complain and insist they fix it. Beyond that, for all I know they may charge me for moving my phone service to a different pair! ------------------------------ Date: Thu, 6 Jan 94 07:54:38 -0500 From: padgett@tccslr.dnet.mmc.com (A.

BTW: IMHO, BT does a disservice to the UK consumer by always listing city codes with the leading "0"; the consumer is going to have trouble understanding that the "0" is an access code, not part of the city code. I think the +1 code for the NANP being the same as the 1- access code for long distance within the NANP isn't a coincidence. ATT invented the international plan ... When I first saw country codes in the telephone book years ago, I wondered why the USA code wasn't listed. (Some droid figured: "but you don't NEED that from the USA". Never mind businesses trying to figure out how to list themselves.) To this day the phone books list places like Izmir, Turkey (+851 according to NYNEX Boston 1993) but omit the USA and Canada. No wonder most ordinary people don't *understand* the system! Back then I called the operator: "What is the country code for the USA?" Oper: "Sir, you don't NEED the country code to dial the USA." Me: "sigh, can I have the overseas operator?" Overseas op: "Sir, you don't NEED ..." Me: "may I have your supervisor please?" Super: "hmmm, I don't know that. Why would you need it?" Me: "suppose I want to place an ad in an international magazine?" Super: "hmmm" Me: "can we ask the overseas operator in, say, London?" Super: "sure!" London: "It is ONE.

The ASTRA sats also broadcast to the UK, Spain etc etc. Its actually owned by a company in Luxembourg, SES. The two birds are actually 0.25 of a degree apart, which is close enough for a dish toi see both (it has to be within 1 degree to see it). I understand that they plan to add a third, ie one at 0.25, one at 0.5 and one a 0.75. The only reason that they aren't spaced any closer is that it would require constant manoeuvering to stop the sats hitting each other as they wiggle slightly in orbit.

Dale <0005517538@mcimail.com> Subject: Announcing networkMCI MCI UNVEILS LONG-RANGE VISION: networkMCI Opens Nation's First Transcontinental Information Superhighway; Announces $20 Billion in Strategic Initiatives Washington, D.C., January 4, 1994--MCI today unveiled a sweeping strategic vision under which MCI and associated partners are expected to invest more than $20 billion to create and deliver a wide array of new branded services to teleconsumers, businesses, research facilities and government customers. "Our notion of the future of telecommunications and MCI is going to have a brand name: networkMCI," said Bert C. Roberts, MCI chairman and CEO. "This strategic vision is the sum of all our plans and opportunities in the new emerging markets with services that consumers, businesses and governments will want at their fingertips as we move into the 21st Century. As a core strategy, it leverages the tremendous opportunities brought on by the convergence of telephony, entertainment and the computer." Transcontinental Information Superhighway Today the company announced, as an initial element of the networkMCI vision, the inauguration of the nation's first trans- continental information superhighway. Often talked about as a key ingredient to keeping America competitive in tomorrow's world economy, the MCI superhighway's roadbed uses SONET fiber optic technology at speeds 15 times faster than any SONET network available today. MCI said that the National Science Foundation Network (NSFNET) is the first user of its New York to Los Angeles SONET fiber system. The NSFNET Backbone Service is the fastest and most powerful of the university, government and commercial networks known collectively as the Internet. "Some people may be surprised to learn that MCI developed these intercity links for the Internet six years ago," said Roberts. "The NSFNET service today reaches nearly 15,000 networks around the world that participate in the Internet." "The Internet doubles in size annually and now links over two million computers serving some six million users," said Vinton Cerf, President of the Internet Society. "When electronic mail interconnects are taken into account, nearly 20 million users conduct their business from labs, homes and offices over the Internet. MCI and its partners, IBM, Merit and ANS, pioneered the use of 45 megabit per second technology for the NSFNET Backbone Service. NSFNET now carries a volume of information that approximately equals the holdings of the Library of Congress EACH MONTH, and MCI's announcement indicates the potential to carry more than 50 times that much traffic." SONET, which stands for Synchronous Optical Network, is a high-speed transmission technology that MCI is using to hasten the widespread availability of broadcast quality videophones, electronic data interchange (EDI), long distance medical imaging, multimedia education, movies on demand, and a single-number Personal Communications Service (PCS) that will use the same pocket-sized telephone anywhere in the world. High-speed SONET technology was deployed in half of MCI's network at year-end 1993, far outpacing its long distance rivals. Under the development program announced today, SONET will be available throughout MCI's domestic network by the end of 1994 and on international routes across the Atlantic and the Pacific by 1995. The company said it will further increase carrying speeds on existing fiber from 2.5 gigabits (billion bits) per second to more than 10 gigabits per second by 1995. MCI Metro As another element of its long-range vision, the company announced the creation of MCI Metro, a wholly owned subsidiary that is expected to invest $2 billion in fiber rings and local switching infrastructure in major U.S. metropolitan markets. Through its metropolitan area facilities, MCI will connect directly to customers and begin providing alternative local telecommunications services. Referring to these connections as "digital on/off ramps" to the nationwide information superhighway, Roberts noted that they would be a vital addition to America's economic infrastructure for the 21st Century. Construction has already begun in Atlanta, with completion expected there by mid- year. Roberts announced the appointment of two key executives to lead this subsidiary. Executive vice president Gary M. Parsons will be chief executive officer of MCI Metro, and senior vice president Nate A. Davis will become its chief operating officer. The subsidiary owns properties and rights-of-way in several hundred cities. "MCI Metro will ensure the availability of superior local access facilities at reasonable cost," said Roberts. "During the last decade, MCI was instrumental in bringing the benefits of competition to the long distance marketplace. During the next decade, we must secure those same benefits for customers of local telephone service. In addition, these digital backbone facilities will strongly position MCI in the emerging markets of interactive multimedia and wireless PCS." networkMCI Roberts said that networkMCI is being introduced to the public via a national advertising campaign utilizing television, magazines and newspapers to explain the company's vision to consumers, businesses, investors and potential partners. "When we announced our global alliance with BT (British Telecom) last year, we said that the added financial flexibility would allow us to invest in America's infrastructure, economy and future," said Roberts. "With networkMCI, we have cast a strategy to deliver on that promise, and then some." MCI expects that other partner companies with complementary skills and resources will participate in projects within the overall networkMCI vision, through equity stakes, joint ventures or other business arrangements. "As telecommunications, computing and television converge, no one company will have the infrastructure and the skills to do everything alone," said Roberts. "Partnering is smart strategy for the 1990's, and MCI has proven repeatedly that it doesn't have to own and control another party in order to work together effectively." MCI cited a number of customer usage trends underlying the decision to make the additional multibillion dollar investments. The company has been growing more than twice as fast as the long distance industry as a whole, and is winning the lion's share of growth in the booming market for international calls to and from the U.S. Data traffic is another major growth factor, with business customers' usage of data communications expected to surpass voice by 1998. In wireless communications, the superior performance of the emerging PCS technology is expected to help drive the total number of wireless devices in the U.S. to 70 million by the turn of the century, which will increase network usage. "Beyond the long-term vision," Roberts continued, "there are a number of immediate benefits that networkMCI brings to the everyday, workaday MCI network. We have created this long-term strategy to meet the demands of a nation of teleconsumers who use telecommunications more frequently and in more ways than ever before. American businesses of all sizes want competitive advantage from their communications. And potential partners in this arena want to create new opportunities. With networkMCI, there will be a clear path to follow." MCI, headquartered in Washington, D.C., offers a full range of domestic and global telecommunications services through one of the world's largest state-of-the-art networks. With annual revenue of more than $12 billion, the company is the second largest long distance provider in the U.S. and has more than 65 offices in 55 countries and places. ------------------------------ Date: Thu, 6 Jan 1994 01:23:50 EST From: Paul Robinson Reply-To: Paul Robinson Subject: "Caller Pays" Cellular Airtime Organization: Tansin A. Darcos & Company, Silver Spring, MD USA Recently, someone announced that Colorado would be having calls to 579 exchange charged for as "caller pays" cellular airtime in addition to toll charges. It's been asked whether or not people could call this number from out of state. The AT&T Operator quoted me the standard 26c for a call to 303-579. But let's not forget that long distance calls are going to net between 2 and 5c in local termination charges from the carrier anyway, so the caller is paying something for the connection. The person who mentioned this told that U.S. West offered a number to call 1-800-USW-BILL for questions. Surprizingly enough, this number does work from Maryland. That 800 number apparently handles surcharged lines including 900, 976 and cellular airtime. The clerk, a person with a very strong foreign accent, indicated that the 579 exchange is a "caller pays" exchange. If someone (in Colorado) calls a 579 number, the caller pays for the airtime. If the user of a 579 number calls someone, they pay for their airtime. I asked whether this was something akin to a 900 or 976 number, trying to explain to the woman what I meant (a number where the called party gets a fee for each incoming call) and apparently she got the gist of what I was trying to point out, in that the caller is surcharged for a call made to the number. ------------------------------ Date: Thu, 6 Jan 94 10:14:41 EST From: Carl Moore Subject: Dialing Changes for Delaware I have heard from Carl Drake, over whose name a letter had been sent to Delaware customers regarding new area code 610 in Pennsylvania.

Pat: I too signed up of the Sprint Modem offer. However, I apparently signed up too late. I talked to a Sprint Rep on Oct 6 about the Dvorak offer and then switched to Sprint under the assumption that I would be receiving a modem. I then waited for it to appear in the mail. In November, I received a bill from Sprint on an existing (but forgotten) Sprint account that I had. It listed only the $7 charge for my calling plan but no actual calls. I called Sprint to enquire about this and I was told to try the 1-700 number to verify my long distance carrier. It was still AT&T! This would explain why I had not received my modem; I hadn't made any calls on Sprint yet. Well, the Sprint rep told me the easiest way to rectify this was to call my local company (Cincinnati Bell) and tell them to switch me. This I did. Still, I waited and waited and waited for my modem. When I called at the end of December to enquire about the status of my modem, I was informed that since I had signed up after Oct 1st, I was too late -- there were no more modems to be had. Wanting to minimize the amount of hassle (my life is currently preoccupied with the birth of my second daughter), I just asked Sprint to credit my account with the amount of the LD switching fees so I could switch back. I'm relating this tale of woe so that (with clear conscience) David could send me his "extra" modem. (I'm sending him a copy of this directly). I will gladly pay for shipping. And should he ever receive a nasty-gram demanding the return of the modem, I will return it to/for him. After all, he would be doing me a favor, and I want to minimize his hassle.

With 500 channels you now open the way for more programmers. What cable system is going to give a small time programmer access to one of its 50 channels? Not many unless the programmer has a proven track record. However with 500 channels they can try many different programmers and let the consumers decide what is popular. How many cable companies are carrying the "outdoor channel" 24h/day? How many people have even heard of this? If you have a satellite dish check out F2/3. Programming is so/so at best. A few good shows and lots of commercials for gold prosper club.

I don't HAVE ACR (or other CLASS services) on my residential lines. However, the first public announcement of the service was over two years ago by Bell Atlantic, at a National Communications Forum in Chicago. Ray Albers discussed the service, indicated the pricing and played a recording of the announcement he received attempting to call such a line after dialing a *67 prefix. The first service was in C&P Maryland, but it has probably been offered elsewhere in Bell Atlantic by now. In discussions about this service, I don't recall "... too scared to answer ..." being a reason for wanting the service. It was primarily a tool to avoid unwanted calls (not repeated annoyance calls, just unwanted ones). [I recognize some folks treat any unwanted call as an "annoyance", but the intent is to avoid calls even from phones that have never called before, so that Call Block is not a reasonable option.] In fact, Bell Atlantic was offering ACR for a small monthly fee even to those who did not have any other CLASS features! The idea was that the caller doesn't KNOW if you have Caller ID, but you might be willing to use ACR as a primitive means of screening out a "class" of callers -- those that suppress Caller ID delivery. They won't ring your phone OR generate call waiting tones while you are on another call. If you have call forwarding on a line with ACR active, the call will not forward. Also note that telco can elect to turn on supervision when connecting to the ACR announcement, so the call will be considered "completed" for billing purposes. Also note that Bell Atlantic was offering ACR on a user-controlled basis; customers can turn it on and off as desired. See Bellcore TR-NWT-000567 for other details.

Firstly V.42 requires that both modems have to have that feature enabled. Secondly it is most useless feature ever put into modem. Its good for marketing people to brag about and give false advertising about how faster modem will transmit data without pointing out when it happens. The V.42 uses Limpel-Ziff compression scheme that is based on generating dictionary as you transfer a file. What that mean is, it will not compress as you type. The compression ratio is related to the type of file you will send. The text will compress to about 25 % of its original size any other files like binaries have much lower compression rate. But here is the catch normally ALL files are compressed by PKzip, ARC or ARJ LHA GIF programs. Those are using precisely same algorithm as V.42. So those files are not compressible. If you try to compress them again the file size will be larger than original. The only time you might get any benefit from compression is when you get screens of text send to you. Again you will trade size of the file versus time (it takes time to compress on a fly) versus link speed. ... So the benefits of V.42 for the user are minimal!

This seems to cover almost every packet or character mode interface in the CCITT world at least. As far as I know, they are not implemented yet by any of the operators. Whether they are terrible or not, time will tell, but I expect they will be dire. One of the main technical issues seems to be that they are very expensive to provide with TDMA, and with the GSM TDMA in particular. There is a new project in the the ETSI GSM group called GPRS (GSM packet radio services?) which might provide a multiple access scheme more suited to data traffic. If you want a comparison, try the US CDPD spec that provides data with AMPS. There is also a data message service (SMS) and I believe that this is is available from some operators. >> 2.

In the abstract, it makes some sense. On the other hand, surcharged numbers are a pain for callers, local telcos, and long distance carriers since the prices tend to be mysterious and the bills at the end of the month often an unpleasant surprise. How long do you think it will take for someone to complain to US West "nobody told me that a call to 1-579 cost 65 cents* a minute"? If it's as much as two days after the first bill is sent, I'll be surprised. The day after that, people will demand 579 blocking, like 900 and 976 blocking. In concrete terms, it's basically impossible to implement long distance calls to surcharged given the way that toll charging works in the U.S. Inter-LATA toll rates are based entirely on distance. There's no provision for passing around surcharges from one carrier to another -- that's why surcharged numbers like the notorious 212-540 only work from points where the local telco carries the call. The only exception is 900 numbers, which have an extremely complicated billing setup that would be impractical for individual cellular customers. I suppose that we could reserve a prefix in each area code (900, perhaps) to be used for local surcharged numbers and try to set up some arrangement for settling the surcharge amounts among various carriers, but it seems like a awful lot of mechanism for a small set of users. Also, experience with 900, 976, and 540 numbers suggests that a lot of callers will be extremely displeased to find yet another kind of phone number that costs extra and has to be blocked, passworded, etc. Regards, John Levine, johnl@iecc.com, jlevine@delphi.com, 1037498@mcimail.com * - a plausible guess, 50 cents for airtime plus 15 cents for toll ------------------------------ Subject: Re: How are VCR Plus+ Numbers Generated From: a_rubin@dsg4.dse.beckman.com (Arthur Rubin) Date: 6 Jan 94 16:55:30 GMT Organization: Beckman Instruments, Inc.

I think he is able to use both lines and is merely getting crosstalk. If that is the case, it is not a "touching conductors" problem at all. It is probably just a case of someone whose house was wired with quad wire (back when Y & B was power for the lights on the Princess phone) who will always have crosstalk.

To clear up how it works in the Dallas/Fort Worth Metroplex, I'll just expain it then respond to David's comments. Dallas county is mostly in 214 area code, Tarrant county (Fort Worth) is mostly included in 817 area code. The area in between the two cities is all suburban towns. The two cities just sort of run together. When dialing within one area code, in the Metroplex, you only dial seven digits regardless of whether it is a GTE or SW Bell number. When dialing from one area code to the other you dial 1+, just like you would from any other two area codes. The difference is when the number being called, *or* the number being called from, is a "Metro" number. "Metro" number means the call is no longer a long distance call, rather the owner of the Metro number is paying a higher monthly charge, but can call or receive calls from 214 or 817 without paying long distance rates. In this case you dial the area code and exchange, without the leading 1. I personally don't have a metro number so I can't give any particulars about the cost. These metro numbers were provided so that people and businesses can be reached easily and inexpensively by friends and customers outside their area code, but potentially next door. I have lived in Dallas/Ft Worth for almost three years and I have never dailed any differently when I lived in SW Bell or now that I live in GTE service area. > One major annoyance was the percentage of calls into GTE that went > high-and-dry.

Hmm, perhaps in the year 2040, someone will write an article about the rapidly-changing 1940s. Atomic bombs and computers were invented then, and just look at the impact computers have had on society: why, we can use our wristwatch PDAs to download the Encyclopedia Galactica directly into our brain cells. By contrast, this newfangled teleportation technology is just an evolutionary change ... The point is, when we consider the impact of airplanes, automobiles, etc. from our perspective, we are really compressing eighty years of history. A fair comparison with computers would require a similar eighty-year perspective. It was some time, for instance, before automobiles could be driven reliably by someone who was not a skilled mechanic. It took even longer for automobiles to change society in fundamental ways (the suburbanization of America, etc). The same is even more true for airplanes. It was decades before the invention of jet aircraft and other developments made flying widely available. As recently as the late 40s, a transatlantic flight cost the same as a semester at Harvard. Cheap flights for the masses didn't become a reality until US deregulation barely a decade ago. On the one hand, computers are still an "elite" technology, as user-unfriendly to the average user as the Model T was to the mechanically challenged. We can anticipate that computers, just like cars and planes, will need a few more decades before they become widespread and commonplace enough to truly change the way we live. On the other hand, however, in a very real sense, it won't take a few more decades; it's already happened. Computers have already had an enormous impact on the way we live, but it's overlooked because it's indirect and behind the scenes. Computers are ubiquitous and invisible, embedded in other products and (especially) services. The fact that you are able to book a flight tomorrow (not to mention a hotel room and rental car) is thanks not just to aircraft technology but to computerized reservation and scheduling systems. You could argue that this is merely a quantitative change, not a qualitative change: computers merely make the process more efficient. But this is not so: a sufficiently large quantitative change eventually becomes a qualitative change. Instead of merely doing the same thing more efficiently, you can do new things that would never have been considered previously. For instance, a modern, mechanically reliable car lets you commute fifty miles a day to work and back, every day. You can't do that with a horse. Early cars were merely faster horses; modern cars are something qualitatively different. Without computers, even an army of airline clerks couldn't manually synchronize takeoff and landing times across the continent, not unless air traffic levels were several orders of magnitude smaller than they are today. Again, this represents a qualitative change. No one would fly on routine overnight business trips, or fly home for Christmas. The tourism and hospitality industry, one of the largest employers, would hardly exist in its present form. We can generalize this: computers make high-volume applications practical, and make it possible for companies to offer many services widely and cheaply. Without computers, many such services wouldn't even exist because the market wouldn't be large enough to outweigh the fixed overhead costs. Others, such as air travel, would be restricted to an elite or moneyed group, and would therefore have very little impact on society as a whole. When considering the impact of technology, we tend to focus too much on things that are flashy and highly visible. A generation ago, people figured that by now we'd be zipping around in rocket ships and flying to work with our own personal jet packs. Few bothered to predict simple things like fax machines. And similarly, when we look back on the twentieth century, we tend to focus on cars and planes and space shuttles, while we overlook the unobtrusive things that have had an enormous indirect impact. Consider plastics: one of the most important inventions of the 20th century, yet often overlooked because they too are behind the scenes and "internal" to other products. Consider air conditioning: without it, Charlotte, Atlanta, and Las Vegas simply wouldn't exist in their present form as business centers, and the massive ongoing population shift to the Sunbelt wouldn't be taking place. And consider computers. In the future, they will be embedded into other products in ways that would seem extravagant or preposterous to us (consider the intelligent volleyball and the smart spray paint in Vernor Vinge's "Marooned in Real Time"). And their impact on society will be as great then as it is now. (I'll let someone else argue the case for telecom technologies; this is already far too long).

Date: 6 Jan 1994 23:00:18 GMT Organization: University of California; Santa Cruz Back in the days when you could walk into a telephone office and pay your bill in cash, there were a bunch of pamphlets in a rack on the wall giving things like tips on telephone usage, the history of the telephone, how the telephone works, etc. I remember one of these had an illustration of rural telephone service using a carrier system operating over the power wire. In this case they used the high-voltage line for the carrier, isolated from the telephone equipment by a high-voltage capacitor presumably installed by the pwoer company for the purpose. The booklet didn't go into detail as to whether there were multiple carrier frequencies so that several subscribers could be served on one power line. Then there are articles in magazines from time to time, and maybe commercial products you can buy, that use the 120v house wiring for conductors; but in that case the interest is in communicating just within the building, or maybe to nearby houses connected to the same transformer. I don't think you'll get carrier frequencies to go through a power transformer and on to the high-voltage side and back through another transformer to the 120v side on another circuit. I believe the power companies also use carrier current for signaling and controlling their relays and things, again working on the high-voltage side of things so they don't have to go through transformers. haynes@cats.ucsc.edu haynes@cats.bitnet ------------------------------ Subject: Re: Connecting Two Phone Lines to One Phone Jack Reply-To: krehberg@vnet.IBM.COM Date: Thu, 06 Jan 94 17:35:21 EST From: V2ENA81%OWEGO@zeta.eecs.nwu.edu Quoted from mcneill@ngt.sungard.com's message of Wed, 5 Jan 94 10:03:42 EST: > On a side note, I recently called NY Telephone (or NYNEX as they want > to be called now) about getting a second phone line installed in my > apartment.

Perhaps they were trying to sell you installation of the wire INSIDE your house. That is the extra $80-$100 or so. If you just want them to put a wire up to your network interface (typically in the basement of your apartment) that will cost you more like $85 from NYNEX. They will always assume the most expensive option, so you say "just hook your wire up to my building's interface box and activate my service". It's then your responsibility for the inside wiring. On your point about four-wire hookups, NYNEX will almost never install a second telephone line onto the second pair in a typical residential phone cable (probably) for reasons discussed on the Digest earlier in which noise can leak between the lines due to induction. They also want to have an extra modular jack inside their network interface for quick connect/disconnect if things go wrong. Not only that, they do want to make money installing inside wiring, which they are NOT obliged to do BY LAW, but are not really itching to tell you that you don't need them to do it for you. You have to be an educated consumer. Read on. > [TELECOM Digest Editor's Note: Not necessarily. Telco outside plant > records are in notoriously bad condition in some places. The rep may As I said earlier, the NYNEX (formerly NY Telephone) telco doesn't seem particularly fond of second pairs. I actually looked into the network interface when they were done with it and they actually installed an extra interface jack and had cut off the second pair on the original wires so I couldn't hope to use them ... those bastards. Anyhow, you can probably hook it up to the second pair after the line is hooked up (and they leave) by using that same Radio Shack converter with your existing phone line inside the network interface and saved yourself some wiring headaches. Remember to tell NYNEX only to bring the wire to the network interface box in the basement. I told them I wanted them to do that in my old house, and they were more than happy to charge me the cheaper $85 for simple pole-to-house hookup and activation. I now live in an apartment in a semi-suburban/rural area and just recently checked with the local business office and the phone book, and nothing has changed even though it has to go to the basement of the house. In an extreme case, if there aren't any extra wires coming in (kinda unlikely in an apartment) and/or there aren't any more terminals on the pole (in a house situation) they're supposedly allowed to charge you an extra $30-$50 or so bringing the cost to more like $85 + $50 = $135. Then the optional charge for installing the wires in the house would probably bring the cost up to the $185 you stated.

Last I checked the cost for your situation (where they > claim there was never a second line) is $88. It's $88, but if there aren't any more terminals on the pole they will charge you an extra $30 to $50 (depending on the work needed) to add that extra line terminal to the pole. This is information from the technicians and the business office here in Binghamton, NY. These are the same idiots who replaced our two pole-to-house lines twice. Once with two wires, and the second time two months later with a single two-line cable (we lived in a house with two dwellings in it). I think they were training their technicians at the time.

Please review it for us and tell us how to obtain copies. PAT] What's this, Pat? Surely you are aware that Carl is a multi-talented lawyer, author on telecom and all-around consumer advocate? And a ham? Assuming Carl is too modest to review his book, I'll provide: BOOK REVIEW The Phone Book : How to get the Telephone Equipment and Service You Want - and Pay Less by Carl Oppedahl, a Consumer Reports Book ISBN 0-89043-364-X (pb), 1991, a revision of the book originally published by Weber Systems, Inc in 1987 as "The Phone Book" This book is a non-technical, "consumer-oriented" collection of information on telephones, telephone service, long-distance carriers, cellular carriers, and reference lists of PUC/Consumer Advocates for each state. The most technical content is a GOOD summary of what an REN is (and why a consumer might be interested), what the USOC codes like RJ11 mean (with pin/wire color information) and how to parse the FCC Part 68 registration number on equipment. The remaining 300+ pages consist of about 200 pages on how to wire one- and two-line telephones and troubleshoot the installation, intermingled with 100 pages of useful (and probably well-known to Digest readers) information on long-distance carriers, cellular/fax/ answering-machines and typical problems in connecting them, dealing with the Phone Company and how to read a phone bill. There is probably more information in this book than most consumers need, but it tends to be information they would not otherwise easily find. Those who need only wiring information might feel more at home with some Radio Shack-style publication, but they would be missing out on the substantial background information mingled in with the technical. Occasionally, there are little anecdotes to illustrate a point. For example, p. 96 mentions "Ruth's" inability to get Equal Access of any form when she moved to Townsend, Tennessee [pop. about 300, so this isn't an oblique PAT reference -- or is it?]. Carl indicates here that even without Equal Access, Ruth may be able to save money by using one of AT&T's discount plans. (It may not occur to many such captive customers that the discount plan can apply even if they have no choice in IXCs.) Some complaints: -ANI is defined as the service we here call "Caller ID", which will be confusing when talking to those who know the difference. -Quad wire is blessed as a method of installing 2-line telephones, and as a general inside wiring method. (Modems and their problems are not high-lighted in the book, but Carl does mention how to get around the A-lead control some modems have, for example.) -The cellular information should include information on ESN-cloning and other problems with cellular service. -Information (see below) useful to apartment dwellers is indexed under the term "multiunit buildings", not under "apartment". (In general, there is little "lawyer-speak" in the book.) SUMMARY: For its audience, this is an excellent reference book. BIO: Carl Oppedahl is a graduate of Harvard Law School and a practicing patent attorney. As a consumer activist, he has championed the interests of consumers in obtaining cost-effective telephone service. +++++++++ To get back to the original topic, Carl's book has several pages of information on various Network Interfaces and FCC/state rules on where/how such interfaces and demarcation points interact. On p. 29, describing NI Jacks in multiunit buildings: "In New York, for instance, the jack is located within the premises of each individual tenant. In Illinois the jack is located at the point where the telephone wiring first enters the building, generally in a basement room. (In a state like Illinois, you and not the local telephone company are responsible for the maintenance of the wiring running from the basement to your premises even though the landlord may not allow you access to such wiring. ..." Carl does indicate that such wiring should be maintained by the landlord at no cost to you, just as such electrical wiring is maintained. (Check your lease.) He lists 14 "renter-beware" states that make the renter responsible for running from the basement any wiring needed for service, such as a second line. He also lists 2 "interface- unfriendly" states that do not require TELCO to install (at little or no charge) a network interface at customer request on new service orders.

That is the problem. I know that they are not shorted because I can make two seperate calls on each of the lines, however I can HEAR the line one conversation when I am using line two. I have heard people talking about how when you run four conductor wire (like from Radio Shack) and use two conductors for one line and two conductors for the other you often get bleed over.

So, given a standard 2400 baud modem using a modified quadrature amplitude modulation scheme, you could conceivably get this level of thruput. Its all a matter of how sensitive your equipment is to detecting minute phase shifts and amplitude changes in the carrier, then it could be quite easy to get twelve bits of data transmitted with each baud. Think of it this way: Each baud is represented by a 360 degree sine wave. You can vary the phase of the sine wave to actually transmit multiple bits for each baud. For example, early "dibit phase shift keying" was a modulation scheme used by 1200bps modems. The modems were really 600 baud modems, but each baud transmitted two bits, depending on how much "out of phase" the baud's sine wave was. For instance: 0 degrees out of phase = hex 00 90 degrees out of phase = hex 01 180 " " " " = hex 10 270 " " " " = hex 11 So, by varying the phase of each baud's sine wave, you could technically transmit two bits of data for each baud. Early 9600bps modems used this same method. 9600bps modems are still technically 2400baud modems - there are only 2400 signal samples (or sine wave occurances) in each second. Using a modified phase shift keying, you could transmit 4 bits of data for each baud, hence, 9600bps. Now, sine waves have more than a phase charactistic. They also have an amplitude. You can modulate a carrier wave's signal via amplitude - tune to a local AM broadcast station, they're using amplitude modulation to transmit their signal. If you combined the two methods -- phase shift and amplitude -- you can transmit many bits simultaneously by modifying those two characteristics. For example (and I don't know if this is technically feasible, given our current technology) if you could measure a 1-degree shift in the phase of a carrier wave, in conjunction with 23 different amplitudes, then theoretically you could transmit one of 360x23 unique "values". 360x23=8280, so we could then use this combination to represent one of 2^13, or 8196, different values. Since we're transmitting 13 bits per baud, multipled by 2400 baud per second, we're getting an effective throughput of 13x2400, or 31200 bits per second, uncompressed. Of course, I don't know if this is how Hayes does it, but remember, you can only modulate a sine wave one of three ways: amplitude, phase, and frequency. Ain't technology wonderful? Michael P.

Up till recently at least, the CRTC (Canadian FCC-analogue) would not license so-called "single-faith" radio or TV stations.

Not unless Caller ID blocking prevents you from making a 1+ long distance call (which it doesn't). There is no way to block 800 ANI short of not calling the number. Even the traditional methods of blocking Caller ID do not work: a) you can't call an 800 number by using a calling card; b) calling through the Operator doesn't block your number (on AT&T, operator assisted 800 calls still deliver the correct ANI to the recipient, and other carriers do not have operator assisted 800 calls); or c) calling over non-SS7 facilities, as SS7 is not required to support 800 ANI. This is why it works for 99.5% of all calls.

Another service that the telephone company can offer to make money. 800 number ANI blocking. For a small monthly fee, your 800 calls will go through, but _you_ will have to pay for them. In exchange for actually paying for the service, your ANI will not be transmitted.

There already is blocking for 1-579, and 1-976 blocking, at least for people familiar with using telephones in Colorado, New Mexico and other "civilized" parts of the country. In these parts of the country -- assuming they are not pressured to change -- dialing a "1" before a seven digit number, or after conversion the local area code, is a clear and deliberate indication that the call is toll. If you do not know that, then you simply will receive a polite "please dial 1" or "please dial 1 303" message when you attempt the call. This simple solution removes many of the problems with charge calls that become present when you allow seven digit toll calling. This would have prevented -- or at least lessened -- the New York pager scam, and can reduce the problems with 976 numbers. And for cellular services, unlike 900 and 976 like numbers, the charge will probably be a flat rate, published in the phone book, or available from the operator upon request. Ronald B.

If you enable it, it automatically answers the call and plays a refusal message, than hangs up. What I see as different between this box and the telco's feature: 1) You don't have to beg the ACLU for this feature, after having begged them for CNID. 2) No monthly charge beyond the CNID. 3) You need to wire the box in series with all your extensions, otherwise you won't get the ring suppression on the other ones. 4) I doubt that it interacts well with Call Waiting. 5) The ability to set the refusal message (I don't know if this particular box has it, but doubtless others will). Big win. So, there are interesting tradeoffs. [TELECOM Digest Editor's Note: Plus which, the call *supervises*, and the scorned calling party gets to pay for a thirty second message telling him his call is unwanted. :) Some say that condition should be the default on this sort of thing, but at least when the telcos do it they can optionally toggle it either way. I am reminded of this guy who had a phone line installed in a remote area which he used only occassionally. The number was never given out, and he used it maybe once a week for a call or two, but he wanted a phone available when he needed it. The first thing he noticed following installation was how many wrong numbers this line was getting; like three or four a day from all sorts of people who were looking for someone or something else -- there was no set pattern to the wrong numbers. He knew for a fact no one would ever call *him* on that line because he never gave to the number to anyone for any reason. His solution was to put a real cheap answering machine on the line with an outgoing message which said, "You have reached a wrong number. For your convenience, this line is answered 24 hours per day by this recording. The person or company you are seeking is not at this number. Because of your carelessness in dialing, you have been charged for this call. Goodbye." He later said the funny part was how many people paid absolutely no attention and at the tone went ahead and recorded their airline reservations, questions for customer service, requests for songs to be played on the radio, etc. A few did actually listen and take note of the message; many of those chose to respond with anonymous (of course) obscene incoming messages, some made sounds into the phone which resembled belching or passing of 'gas', a couple were gales of hysterical laughter, etc. He finally changed his outgoing message on that line referring to it as the "Telephone Company Wrong Number Respository". ------------------------------ Date: Thu, 6 Jan 94 16:45:55 -0500 From: padgett@tccslr.dnet.mmc.com (A.

On my dial-ups I use Caller-ID to validate the caller before permitting connections. If the CNID is blocked, I just do not answer the phone but the line is still occupied until the caller hangs up. Even if I did not have CNID, I doubt that many people would be willing to use a Demon Dialer if they could not block CNID since they would not *know* if I were logging.

Then you probably don't receive a lot of calls from telemarketing idiots and nosy scam artists. We go through periods at work when we're inundated with those, and calls from telemarketing machines (our exchanges are low numbers in the 201 area). Telemarketing calls are an enormous time-waster, and more than half of the investment scam callers are pushy and rude.

Has anyone seen one of these? Yah, modern Panasonic VCR's with VCR/Plus has a thumwheel on the remote control which lets you cycle through the days. It also has a meager explanation of VCR/Plus and lets you graphically program the channel positions into the VCR so that it will automatically know which channel is which. It had some kind of cross-reference listing on it as to which channels go where so that the codes might actually work for your local cable system. Prevue Guide (the TV-Guide channel that allows the cable system to automatically select the preview commercials based on your area's channels) also provides VCR plus on almost all the programs in the commercial section, and at least some of them in the program listing section. Pretty cool, if you ask me. But I'm not among those millions of people who can't program something as simple as a VCR. Come to think of it, just setting up this Panasonic VCR for VCR/Plus would give this kind of person a coronary.

The problem, of course, with using ANI with cellular numbers for enhanced-911 is that it only gives the 911 people some of the information they need. It will give them your cell number (assuming that the ANI works correctly) so they can try calling back if the number is disconnected but there is no way for them to translate this number into a location since the cellular phone could be anywhere. With normal 911 the phone number is translated to a street address, and since houses (with the possible exception of mudslides in LA :-) rarely move, the 911 operator (and thus the police/fire department/whatever) can be relatively sure that that's where you're calling from so that help can be dispatched to the right address if you are unable to communicate. With a cellular phone the information that is _really_ needed is the cell site that the phone is communicating with. This could, in turn, be translated to a street address that would at least get the police to within a thousand feet or so of your location in the event you are cut off, don't know where you are or are unable to communicate. You can imagine the frustration of a 911 operator talking to a child over a cell phone (say, after a car accident) where the child may be unable to explain where the car is and the 911 operator helpless to narrow down the location at all without help from the cellular provider (and a lot of valuable time lost). Coming up with a way to communicate cell site address to the 911 operator is non-trivial and will probably take a fair amount of effort to implement. Since I don't work on that side of the company I'll let someone else explain the technological challenges.

I am reminded of this dude twenty years ago who used to buy CB radios from Radio Shack at a time when CB's were easily modified to install an additional 250 channels and with luck oscillate clear up in ten meters. He'd buy the radios and modify them, then resell them to folks. Naturally, once in awhile there'd be an accident. He'd mess up something, ie, the radio would blow up. In that case, he'd scrap all the internals he wanted -- the chips, etc -- for spares to use elsewhere and he would *carefully* put the unit back together otherwise, *carefully* repackage the remains and take it back to Radio Shack to complain the unit was defective. Now the RS clerks didn't pay any attention; they'd just swap him out and send the 'defective' unit back through the system to their regional center. Over time the 'defective' CB would find its way back to the factory in Korea (Hong Kong? China?) where it was made. Just imagine the scene: the Chinese factory workers open the radio and look inside. As they look closer, they squint their eyes and proclaim, "Holy $%^%# ... look at this! No master crystal, no trim-pots, no final ... how did this thing pass quality control and get out of here to start with!" ... :).

Ditto here. In past two days San Jose Mercury telemarketers have managed to ring all four university extensions on my secretary's desk (selling newspaper subscriptions to Stanford University office extensions? -- but then, who expects intelligence from telemarketers). Let me once again pitch the simple idea that telemarketers should be allowed total freedom to call anyone -- but required to do it with CNID from a special "telemarketing area code" prefix, like 300 or 400 or ??? (just like the "Advertisement" warning at the top of commercial inserts in reputable magazines). Those who wanted could then buy a cheap black box to block all such calls. No First Amendment problems, no "do not call this number" databases to prepare and maintain, burden of protection entirely on the callee (but easily done), etc. ------------------------------ From: jsaker@cwis.unomaha.edu (James R.

This is the scary part simce everywhere I go I see regional carriers attempting to eliminate "flat" and "unmetered" plans. As telecommuting and information hightway access begins to take hold, the elimination of unmetered local service is the biggest threat to individual connectivity that I can imagine. Of course, the biggies (Compu$erve, Plodigy, etc.) will have 800 numbers and just pass the cost along, but one might expect amateur BBSs, SLIPs, and the like to become much less popular. The biggest threat would be to the infant telecommuting industry and the home office which relies on unlimited local service and the best means for achieving the Clinton/Gore "20% reduction in commuting" would go up in smoke. True, TANSTAAFL still applies and I suppose metering is inevitable particularly since it is both cheap and desirable for the Telcos. The only advantage that I can see for the consumer would be that with metered service, the subscriber would have a right to a call detail listing the individual calls by called number, time, and duration.

These corrections come right out of the ITU-T (ex-CCITT) text for V.42 and V.42bis, as well as info from one of the authors of both standards. General comments, of course, are mine. :-) In article PURWIN@XANADU.XYPLEX.COM (Janusz Purwin tel 508-952-4711) writes: > Well don't worry about if it does work or not. Firstly V.42 requires > that both modems have to have that feature enabled. Secondly it is > most useless feature ever put into modem. Its good for marketing > people to brag about and give false advertising about how faster modem > will transmit data without pointing out when it happens. First off, V.42 *IS* an important feature, especially for high-speed modems. If you didn't have some type of error control, you could run into all kinds of problems. Remember, high speed modems (e.g., V.32bis and the up-and-coming V.34) really stretch the limits of a normal POTS line. I won't bore everyone here with the details, since that's not going to be anything new to anyone anyway. Second, V.42 (and MNP3) strip off the start/stop bits, thus using only 8 bits per character instead of 10. For a V.32bis connection, this means going from a throughput of absolutely no more than 1440 cps to somewhere around 1650 cps to 1724 cps (after protocol overhead). See the discussion over in comp.dcom.modems for more details on this. But when have you ever seen a vendor 'brag' about this? > The V.42 uses Limpel-Ziff compression scheme Sorry, but V.42 doesn't do any compression, period. V.42 is an error control protocol, as is clearly indicated by the title of ITU-T (ex-CCITT) Recommendation V.42: "Error-Correcting Procedures For DCEs Using Asynchronous-to-Synchronous Conversion" (originally in all-caps). V.42 is an HDLC-based error control procedure. It operates in one of two modes: LAPM (Link Access Procedure for Modems), which is its primary mode, and an alternate mode specified in Annex A, which is basically an MNP4 clone (added to provide support for older modems that don't have V.42). If you can find anything about data compression in Recommendation V.42, you must be reading a different version than the one that was written by the CCITT (now the ITU-T). Now, assuming that your reference to V.42 was a typo, and you really meant V.42bis ... > The V.42 uses Limpel-Ziff compression scheme that is based on > generating dictionary as you transfer a file. What that mean is, it > will not compress as you type. First off, V.42bis uses a modified version of Lempel-Ziv-Welch compression. Various extensions were added to LZW to make it more effective in a modem environment where it would be required to compress continuous streams of data. It compresses whatever data it can, regardless of whether that data is typed by you, is a screen of data from the remote computer, or is a file being transferred. Second, even if V.42bis only worked when *FILES* were being transferred, and not when text screens, etc., were moving, would you please explain to me how it's supposed to know the difference? :-) Think about it ... > But here is the catch normally ALL files are compressed You seem to be assuming that the only use for high-speed modems is downloading files from a BBS. This is, in fact, far from the truth. There are lots of people using modems to access various other online applications, and V.42bis can definitely help a *LOT* in this case. And even if all you're doing is snarfing up some file from a BBS, isn't it nice to have those file listings move faster? Hey, if I'm grabbing a file from a BBS, I usually have something I want to do WITH that file -- I'd rather get on with that than sit there waiting for screen after screen of info. > by PKzip, ARC or ARJ LHA GIF programs. Those are using precisely > same algorithm as V.42. As already covered above, V.42 isn't data compression, and V.42bis (which *IS* data compression) uses a modified version of LZW that is designed specifically for the modem world. In fact, zip, etc., usually do better than V.42bis, so where possible (and it isn't always possible) you're better off compressing files with something like zip or gzip prior to sending them. > So those files are not compressible. If you try to compress them > again the file size will be larger than original. Not true. Unlike MNP5, V.42bis is nice enough to not expand pre-compressed data, so the worst you'll get is 1:1. For more details, refer to section 7.8 of Recommendation V.42bis ("Data compressibility test"). > ... So the benefits of V.42 for the user are minimal! That depends on what the user is doing. The benefits for YOU may be minimal, and that's fine. But just remember that there are other modem users in the world, and they don't all do things exactly the same way you do.

Yes, it is. But there is an absolute limit (Shannon's Law). The question was about the transmission over a *real* phone line. And that means there exists *noise*.

Gemstar seems to have elected to try to keep the encoding secret, so as to maintain their ability to sell the device, and also to sell to the newspapers the codes. This may be because they couldn't get an effective patent or other form of protection. Unfortunately, they seem not to have anticipated that this strategy would be interpreted by many as a challenge. As a result, almost all details of the encoding were deduced and published in a paper, published in Cryptologia about two years ago. As far as I know, there's no other protection on the encoding, so that no legal barrier prevents a newspaper (at least, one which isn't already under contract to Gemstar) from creating the codes itself and publishing them (modulo the missing details), although there is undoubtedly protection on the VCR Plus trademark itself.

The number associated with her is no longer in service. However, in my search I came across the number for Shawn Larimer. One article listed him as the person in charge. I called that number and left a message. Well, I just received a return call, not from Mr. Larimer, but from Don Sivesind (913-624-5136). He was very nice, even cheerful. When I breifly explained to him my tale of woe, he (much to my delight) said that he would order me a modem right away. It turns out that instead of setting up a new account (which would have trigged a modem order) they re-activated on old account. Well, I'm a "happy camper" now, and not "so" down on Sprint's customer service. Although, this still leaves David in a quandry about what to do with his extra modem. Dan Osborn [TELECOM Digest Editor's Note: Thanks for the followup on this. I'm glad to hear Sprint was willing to work along with you.

It seems that my last bill came in with a munged minutes column of the AT&T portion. (Half of the calls had no minutes value, and there was a $10.14 call to Sacramento at 11pm that said 8 minutes! (The call is my roommate's -- I'm not sure how long it really was for.)) I called AT&T, whose rep suggested that I call NYTel, as the problem was with their printing of the bills. The NYTel rep said that AT&T had messed up the tapes, and that they had dropped the minutes column for calls that were between one and four minutes. (Obviously this is not the whole story -- many of the calls in that range are listed, not to mention the $1.25+/min call to CA!) When I suggessted that I'd like a corrected bill, she said "Oh no, were not equipped to do that!" When I persisted, she called AT&T, and her final conclusion was that AT&T would call her back with the minutes information in about two weeks, and then she would call me. At that point I asked to speak to manager (I consider yelling at droids on a par with teaching pigs to sing). I was told that one would call me back later ... As far as I'm concerned, if they want my money, they'll have to send me an accurate bill. Some of the lines on the bill fail simple sanity checking -- so as far as I'm concerned, the whole page is suspect. Anyone else have a similar experience with them?

Date: 8 Jan 94 08:42:04 GMT Organization: King's College London Could someone please tell me how to phone US 0800 numbers from the UK? Thanks. Maaruf Ali [TELECOM Digest Editor's Note: We do not have '0800' numbers. If you mean 800 (toll free numbers), the answer is that generally you cannot call them from outside the USA. Most of the subscribers to 800 service only pay to accept calls from places inside the USA. Subscribers in the USA who wish to accept toll-free (reverse charge) calls from other countries have numbers assigned to them in the actual format used by the other country. In other words, if there is an 0800 number listed in your directory which states that it rings into the USA somewhere, you can call it. If you otherwise see (in advertising or whatever) a number in the USA marked 800-something, you *cannot* call it from outside the USA under normal conditions. They don't want to accept your call and have to pay for it. One exception to this is that you can call the 'home direct' services of the various carriers and some of these carriers will handle it so that you pay for a call to the USA and the 800 subscriber on this end pays only for the portion of the call which is in the USA. You need to match carrier with 800 number for this however; the carrier of the 800 number is the carrier who's 'home direct' service you need to connect with, *and not all of them will do this*, although I think AT&T and MCI will.

With all the news about phone companies improving their networks for higher speed transmission I wonder if there will be (in, say, five years) correspondingly higher standards for residences. I'd like to anticipate them if possible. Locally, at least, it seems that fiber optics is out of the question since it would require very expensive multiplexing and demultiplexing equipment. For twisted pair copper cable, the industry grades by "level" which is roughly corresponding to speed or throughput. Apparently most homes have level 1 or 2. Level 3 supposedly can handle up to 10 megabits per second, level 4 higher and level 5 maybe 20mbps. I have two questions. Responses by e-mail are welcome. 1) Is there any reason to expect that level 3 will not be sufficient in the near future, keeping in mind what the phone and cable TV companies are likely to provide? 2) Besides cable and jacks, what else should I be careful to specify? (I do plan to specify 4 twisted pairs per cable.) Daren Cline ------------------------------ Date: Fri, 7 Jan 94 17:32:22 EST From: Robert J.

Although I like to think of myself as technologically literate, the user interface for the voice mail system intimidates me. The rather thick user guide lists many features, options and user commands. The system structure is summarized in 6 pages of decision tree diagrams. User commands are things like "*73" (replay a message), and there are alot of them. I already have an 89 page user guide for my ROLM telephone. Does anyone else find this as frustrating as I do? The local phone company uses similar commands to access the new features that have been added to their switch software. I don't mean to single out ROLM, I'm sure other vendors have similar systems and problems. The ROLM PBX has some nice features that I never use because I can't remember groups of commands like "FLASH-*-*-3". The telephone has mutated from an easily understandable electric instrument to a terminal for a complex computer/data switch. It still has the same basic external layout except for the addition of a few extra buttons in some telephones. How can telephones be made easier to use? The local phone companies are going to have a hard time selling new features to their customers if they expect them to press "*-*-FLASH-4-2-#-6-6-6" every time they use them.

Reply-To: mse@ins.infonet.net My understanding of SLIP is that it is a point-to-point dedicated configuration, requiring a modem on the receiving end to be dedicated to a specific user (due to IP I think). I've heard some talk about so-called 'dynamic' SLIP -- where the SLIP connection is made, but through a mux or terminal server, allowing the provider to serve multiple dial-up customers instead of a 1-1 ratio.

I asked it in the newsgroup a couple of months back with no useful response. I would like to know how some of these bulletin boards have 60-100 lines running into them (eg EXEC-PC). Do they simply have that many individual lines run or is there a nifty service that the TELCO offers through a PBX?

Gregoire dannie@coplex.com [TELECOM Digest Editor's Note: Thanks for the compliment, but you overestimate my skills a little. Depending on your application or needs, you can have as many actual lines run as desired. I suspect most very large systems these days however use what is called T-1 or similar, where a large number of circuits are multiplexed or handled over just a few actual pairs of wires. In addition to T-1, there are similar methods for bringing in a large number of circuits on only a few wires. In my own personal applications in the past, I always just had the physical wires, but that was several years ago before the present technology became available. Perhaps Fred Goldstein or one of the *real* tech people here will reply.

This has been going on for over a year. Unfortunately, the only evidence that my friend has is circumstantial (eg: the phone calls temporarily stopped when the suspect went on vacation, and resumed when the suspect returned back to IL). Much of what the suspect is doing is in the way of harassing phone calls, including calls from various payphones in the area where my friend lives, calls at all hours of the day and night, calling pagers and leaving my friend's phone number, etc. Does my friend have any recourse (legal or technological)? He has tried many of the new technological means (I don't want to go into detail, since the suspect has net access and potentially reads this newsgroup), but he's running out of ideas. A legal means might be preferred (since that might help against the stalking as well as the harassment), but just being able to curtail the phone harassment (and it is happening at both his home and his work, so just changing the phone number won't be enough) would be helpful. Nevin ":-)" Liber nevin@cs.arizona.edu (602) 293-2799 ^^^ (520) after 3/95 [TELECOM Digest Editor's Note: There are laws against stalking and harassment in place here in Illinois. If your friend wants to do something about it legally, I suggest that he go to court and ask for a 'peace bond'. If the court agrees the circumstances warrant it, the other person will be told to come to court and the 'peace bond' will be issued against him; he'll be ordered to keep his distance and refrain from harassing activities. Failure to do so will result in his arrest. Your friend may get a run-around from court personnel if he shows up without an attorney so he might want to hire a lawyer to go in and get it done for him. Changing his home phone number will eliminate at least some of the problem, however it is hard to say what might help at work since you don't mention the type of phone system there. Really though, he should not have to change his number at home. That is an inconvenience on him. I think my first steps would be to secure the peace bond and install selective call screening (subscriber can punch in up to ten numbers from which he does not wish to receive calls) on my line. Each time the guy called, I'd add 'last call received' to my list of screened numbers. That would keep him looking for new payphones to use since I'd always keep *his* home phone(s) and office phone(s) on the screened list. If that did not discourage him, then with the peace bond in hand I'd ask Illinois Bell to install a trap on my line. I assume your friend has the stalker's home address and place of employment? Getting served with a court order to lay off might be all it takes; the person might be sufficiently discouraged at that point. What kind of phone system does your friend have at work? Would employees there (for example the operator/receptionist) be willing to help eliminate the problem?

(only want it for > CompuServe mail handling, so low baud would be OK) This is a device that talks to the Merlin KSU using it's proprietary signalling, but can connect to a modem, standard single line phone, or fax machine, and provide ringing and a standard, 2-wire telco line type connection on the output side. If you just want to use the modem for dial out, a much cheaper solution is to bypass the KSU with an exclusion device that will provide protection against interruption to both the Merlin system and the modem, since there is no reason to have the added expense of ringing or an expensive connection to the key system's station side. You can use Proctor's 41434 Voice/Data Privacy module. Install it on one of the CO lines ahead of the KSU. One of the outputs will go to the same place on the KSU where this outside line used to plug in, and the other output will run directly to the modem. When this trunk isn't in use, the modem can seize it and dial out. If the line is already in use, the modem will be blocked. If someone attempts to place an outgoing call on this line from the Merlin system while the modem is using the line, they will be blocked from interrupting the modem transmission. If you have a number of incoming lines in a hunting rotation, and one line is used the least, install the modem access on that least used line.

Don't even try to use pulse in Scandinavia or New Zealand. Why not in New Zealand? You just have to change your numbers so that they are modulo 10. I think since the old telephone dial went 0....9.

The difference is when the > number being called, *or* the number being called from, is a "Metro" > number. Apparently much has changed or you didn't understand it in > the first place. It could look that way if you live in either Dallas or Fort Worth. But if you live near the boundary, the problem is complicated by the fact that some exchanges in the "other" area code are local. So you don't dial the one, even though the number is not metro. However, if you call from one end of either area code to the other end, such that the call is not local, you do dial the one and the area code, even within your own area code. What that all means is you can memorize all the metro exchanges (a big job) but it still won't always help you. Whether a call requires a one or not depends on whether it is local, and that depends on both the calling and the called numbers. So if you recognize an exchange as not being metro and dial the one, you can still get the intercept if the exchange just happened to be local anyway. I found it exceedingly stupid and time-wasting. They only accept one way to dial each possible call and you really can't always guess right.

"This strategic vision is the sum of all our plans and opportunities in the new emerging markets with services that consumers, businesses and governments will want at their fingertips as we move into the 21st Century. As a core strategy, it leverages the tremendous opportunities brought on by the convergence of telephony, entertainment and the computer." Transcontinental Information Superhighway Today the company announced, as an initial element of the networkMCI vision, the inauguration of the nation's first trans- continental information superhighway. Often talked about as a key ingredient to keeping America competitive in tomorrow's world economy, the MCI superhighway's roadbed uses SONET fiber optic technology at speeds 15 times faster than any SONET network available today. MCI said that the National Science Foundation Network (NSFNET) is the first user of its New York to Los Angeles SONET fiber system. The NSFNET Backbone Service is the fastest and most powerful of the university, government and commercial networks known collectively as the Internet. "Some people may be surprised to learn that MCI developed these intercity links for the Internet six years ago," said Roberts. "The NSFNET service today reaches nearly 15,000 networks around the world that participate in the Internet." "The Internet doubles in size annually and now links over two million computers serving some six million users," said Vinton Cerf, President of the Internet Society. "When electronic mail interconnects are taken into account, nearly 20 million users conduct their business from labs, homes and offices over the Internet. MCI and its partners, IBM, Merit and ANS, pioneered the use of 45 megabit per second technology for the NSFNET Backbone Service. NSFNET now carries a volume of information that approximately equals the holdings of the Library of Congress EACH MONTH, and MCI's announcement indicates the potential to carry more than 50 times that much traffic." SONET, which stands for Synchronous Optical Network, is a high-speed transmission technology that MCI is using to hasten the widespread availability of broadcast quality videophones, electronic data interchange (EDI), long distance medical imaging, multimedia education, movies on demand, and a single-number Personal Communications Service (PCS) that will use the same pocket-sized telephone anywhere in the world. High-speed SONET technology was deployed in half of MCI's network at year-end 1993, far outpacing its long distance rivals. Under the development program announced today, SONET will be available throughout MCI's domestic network by the end of 1994 and on international routes across the Atlantic and the Pacific by 1995. The company said it will further increase carrying speeds on existing fiber from 2.5 gigabits (billion bits) per second to more than 10 gigabits per second by 1995. MCI Metro As another element of its long-range vision, the company announced the creation of MCI Metro, a wholly owned subsidiary that is expected to invest $2 billion in fiber rings and local switching infrastructure in major U.S. metropolitan markets. Through its metropolitan area facilities, MCI will connect directly to customers and begin providing alternative local telecommunications services. Referring to these connections as "digital on/off ramps" to the nationwide information superhighway, Roberts noted that they would be a vital addition to America's economic infrastructure for the 21st Century. Construction has already begun in Atlanta, with completion expected there by mid- year. Roberts announced the appointment of two key executives to lead this subsidiary. Executive vice president Gary M. Parsons will be chief executive officer of MCI Metro, and senior vice president Nate A. Davis will become its chief operating officer. The subsidiary owns properties and rights-of-way in several hundred cities. "MCI Metro will ensure the availability of superior local access facilities at reasonable cost," said Roberts. "During the last decade, MCI was instrumental in bringing the benefits of competition to the long distance marketplace. During the next decade, we must secure those same benefits for customers of local telephone service. In addition, these digital backbone facilities will strongly position MCI in the emerging markets of interactive multimedia and wireless PCS." networkMCI Roberts said that networkMCI is being introduced to the public via a national advertising campaign utilizing television, magazines and newspapers to explain the company's vision to consumers, businesses, investors and potential partners. "When we announced our global alliance with BT (British Telecom) last year, we said that the added financial flexibility would allow us to invest in America's infrastructure, economy and future," said Roberts. "With networkMCI, we have cast a strategy to deliver on that promise, and then some." MCI expects that other partner companies with complementary skills and resources will participate in projects within the overall networkMCI vision, through equity stakes, joint ventures or other business arrangements. "As telecommunications, computing and television converge, no one company will have the infrastructure and the skills to do everything alone," said Roberts. "Partnering is smart strategy for the 1990's, and MCI has proven repeatedly that it doesn't have to own and control another party in order to work together effectively." MCI cited a number of customer usage trends underlying the decision to make the additional multibillion dollar investments. The company has been growing more than twice as fast as the long distance industry as a whole, and is winning the lion's share of growth in the booming market for international calls to and from the U.S. Data traffic is another major growth factor, with business customers' usage of data communications expected to surpass voice by 1998. In wireless communications, the superior performance of the emerging PCS technology is expected to help drive the total number of wireless devices in the U.S. to 70 million by the turn of the century, which will increase network usage. "Beyond the long-term vision," Roberts continued, "there are a number of immediate benefits that networkMCI brings to the everyday, workaday MCI network. We have created this long-term strategy to meet the demands of a nation of teleconsumers who use telecommunications more frequently and in more ways than ever before. American businesses of all sizes want competitive advantage from their communications. And potential partners in this arena want to create new opportunities. With networkMCI, there will be a clear path to follow." MCI, headquartered in Washington, D.C., offers a full range of domestic and global telecommunications services through one of the world's largest state-of-the-art networks. With annual revenue of more than $12 billion, the company is the second largest long distance provider in the U.S. and has more than 65 offices in 55 countries and places. ------------------------------ From: vantek@aol.com Reply-To: vantek@aol.com Date: Sat, 08 Jan 94 21:09:02 EST Subject: Phone Phreakers Down South Thought I'd pass this little story along ... Charlotte Observer, N.C. Knight-Ridder/Tribune Business News Jan. 7 -- Another Charlotte company has fallen victim to telephone hackers. Pic 'N Pay Stores Inc., the Charlotte-based shoe retailer, says it got stung for $17,000 by high-tech hijackers who got into the company's voice- mail and dialed anywhere they pleased. Pic 'N Pay filed suit last week against BellSouth Telecommunications Inc., parent of Southern Bell, which made and serviced the phone system in question. The suit in Mecklenburg Superior Court seeks reimbursement for phone bills the retailer had to pay to AT&T, Alltel and Sprint. Southern Bell spokesman Clifton Metcalf declined comment on the case Thursday but said the company works hard on security issues. The suit says BellSouth specifically told Pic 'N Pay its voice-mail system, installed in January 1991, was not vulnerable to fraud. A few months later, Pic 'N Pay noticed strange goings-on. One night, 13 of its 17 local trunk lines were busy, even though only four employees were in the building. Securing the system took a technician five minutes, the suit says. Pic 'N Pay attorney Larry Hewitt said some of the fraudulent calls were made from New Yorkers to the Caribbean. Unauthorized access through voice-mail systems is one common variety of telephone fraud. Altogether, the problem is estimated to cost U.S. businesses and individuals more than $1 billion a year. Pic 'N Pay Vice President Phil Myers said staffers caught the problem before it became severe. Others have been less fortunate. For a week in 1989, drug dealers using computers penetrated Piedmont Natural Gas Co.'s phone system and made hundreds of calls to such places as Colombia, Bolivia and Pakistan, costing the company nearly $70,000. When Piedmont refused to pay AT&T for the charges, AT&T sued. The case was settled for an undisclosed amount. r#QFP ------------------------------ From: vantek@aol.com Reply-To: Date: Sat, 08 Jan 94 21:09:31 EST Su ]qQbject: Dial 511 for Info Another news article to pass along ... The Atlanta Journal and Constitution Knight-Ridder/Tribune Business News 9z ATLANTA -- Jan. 7--Within three months, consumers will be able to dial 511 to get information from an operator about classified ads and the Yellow Pages. The new service -- a joint venture between Atlanta-based Cox Enterprises Inc. and BellSouth Corp. -- was approved Thursday by the Georgia Public Service Commission. Want to buy a used pickup? Dial 511 and an operator will read any ads that help, or fax the information to you. You'll also be able to have the operator contact you as ads come in. "The simplicity of this is the great thing, and you have the added advantage of having an operator to help you," said Kristie Madara, a spokeswoman for BellSouth. "The plan is to not only be able to access this by phone, but eventually by personal computer." The venture, called Infoventures of Atlanta, will use the 511 telephone number the PSC awarded to Cox Enterprises in May. It's currently used to provide a range of information from sports scores to stock quotes for 50 cents a call. The new services will carry the same fee. The new services, which also would allow you to place electronic ads using 511, would be available to all consumers in Atlanta's local dialing area. If that dialing area is expanded -- as the PSC is considering -- the services likely would be expanded as well. "A lot of things are still in the planning stage right now, but I assume this to be the case," said James T. McKnight, vice president of information services for Cox Enterprises, which owns {The Atlanta Journal-Constitution}. Thursday's 4-to- 1 approval followed a sometimes heated public hearing and came over strong opposition from Williams Communications Inc., which was awarded a 711 number last month. Williams Communications, which is owned by Gov. Zell Miller's chief of staff, Virgil R. Williams, argued that: - If BellSouth financially subsidizes Cox Enterprises, then Cox has an unfair advantage over competitors in its use of the three-digit number. - The joint venture would restrain competition between Cox and BellSouth, eliminating service innovation. - BellSouth hasn't gone through the same application process for a three- digit number that Cox and others have. "We feel the objections are just an attempt to delay this," sai attorney Peter Canfield, who represented Cox Enterprises. "We believe that Williams, as a competitor, is trying to delay us from going forward." ------------------------------ From: lockhart@jupiter.sun.csd.unb.ca (S.

These devices typically handle a few incoming lines and 4 to 6 extension phones. They sound ideal for a home or small business installation. They also look like something that would be priced in the $200 to $300 range. What I'd like to know is, are there American sources for these products -- either from US manufactures or imported? If not, why? I know that there are a variety of companies that make small PBX systems, but from what I have seen they haven't been that cheap and they also typically require special phones. I would also be interested to know about PBX cards for PCs that fall into this price range. Last time I looked there weren't any. Please respond by mail. I will summarize if there is interest.

Subject: All Wire Isn't The Same There has been discussion recently regarding crosstalk between pairs of wires in two-pair cable ("Two Phone Lines to One Phone Jack"). A recent BELLCORE bulletin pointed out that two-pair inside wire (AKA station wire or JKT) can be found to have been made in two quite different ways. The cross-sectional view of one wire reveals the plastic outer sheath is formed around the conductors in a cloverleaf-like pattern, holding a certain relationship between the conductors for the length of the cable (AT&T *used* to make their two-pair stuff this way), resulting in less crosstalk between pairs. The sheath of the other type (which AT&T is using now) does not hold the conductors in any particular alignment, but is a loose outer covering. This wire exhibits greater crosstalk when used for two telephone lines. You can detect the second type of cable easily -- it's smaller in overall diameter, the conductors slide within the jacket, and it simply *feels* cheap (editorial comment). In my opinion, the new stuff is junk, and, probably, at a higher cost to the purchaser. I have a roll of General Wire at the shop that is constructed in the "good old way," but several of our suppliers can't seem to find any more of it in their warehouses. I'd recommend the second pair in the new stuff be used only for backup in case the first pair is damaged in some way, and not used for a second service. Such is progress.

Darcos & Company, Silver Spring, MD USA By accident I found something new and unusual. Someone suggested that one of the things being done was to not use as prefixes any number that matches an area code touching the one in question, e.g. in the 301 area code there should not be a 302 or any of the prefixes from Pennsylvania that touch it (since before it was split, 301 touched Delaware). Well, to test it I tried the other area code in Virginia. The one touching 301 is Northern Virginia -- 703. The one in Richmond is 804. The system will not allow me to dial a number with 804 (from a 301 area-code number) unless I dial ten digits, in which case I get the "You must first dial a 1" recording. But I can dial the local area code, so I dialed 301-804 and then picked a random number -- 5000. 1234 and 1000 also give the same recording: "We're sorry, because of an area code change, your call cannot be completed as dialed. Dial again using area code 410. Please make a note of this change. The following tones are for TDD users: " Then, on a TDD device we have in our office, the message comes across "PLS USE 410 AREA". Unique idea -- putting a TDD message into an error recording -- and I'm surprised that I've never heard it done before. ------------------------------ From: ray.mcguigan@ashe.cs.tcd.ie (Ray Mc Guigan) Subject: Computer-Telephony Integration Organization: Trinity College Dublin Date: Sat, 8 Jan 1994 14:31:03 GMT A friend has a number of queries relating to computer-telephone integration.

Some companies would publish _only_ their 800 numbers, and thus reduce the value of your suggestion.

Shannon's Law is defined as C=W * LOG [1 + (P/N)] 2 Where P is the power in watts of the signal through the channel, N is the power in watts of the noise out of the channel, and W is the bandwidth of the channel in hertz. One typical values for a voice-grade analog circuit are: W=3000hz, P=.0001 watts (-10dBm), N=.0000004 watts (-34dBm). This would yield: C = 3000 * Log2(1+250) = ~24,000 bits per second. Due to the nature of the Log function, its easier to increase the value of C more easily by increasing the value of W , rather than P or N. Michael P.

The cell site can send a mobile audit request -- basically a 'ping' of a mobile unit which does not result in a ring. The cell site typically sends an autonomous registration request message from time to time, causing all mobile units which receive it to respond.

PAT] 1) There is no way that a customer in a foreign country can find out which carrier services a particular (800) number. 2) Only the "big three" carriers have "home direct" services. 3) All of the people asking this question are quire willing to pay USD 5.00 + USD 1.50/minute (or whatever the operator-assisted rate is) to talk to these companies (who then will often gladly leave the call on hold for 5 to 15 minutes before answering it. About ten years ago, AMerican industry started telling people, that for our own good, they were moving manufacturing to South East Asia. The American workforce would henceforth be retrained for jobs in: (a) Service (b) Development and Engineering (c) Sales and Marketing In the meantime, the marketing departments of America's "Fortune 500" companies are now staffed with people who have difficulty thinking straight (to put it VERY politely). How else can I describe my experience last October, when I was attending a large international trade show in Paris with 400 American companies displaying their products to 23,000 visitors, and many of them were handing out product data sheets with only an 800-number for contact information? A dozen (American) trade magazines had printed special editions for the show, filled with glossy color ads and press releases, which generally had only the company name (no mailing address, no city name) and an 800 number? Given that the IXCs fall down on their face and refuse to route calls to these numbers, I have only two pieces of advice: I. To the customers: Don't buy anything from a company that has an "International Marketing Manager" who orders up such ads. If they treat customers this way in the "buttering-up" phase, how will they treat you after the sale ? II. To the telecom gang: There should be a business opportunity in setting up a (toll restricted) call diverter line to route calls to 800-numbers. Maybe make the caller listen to a 30 second blurb for TelePassport before giving them a dial tone good only for 800 numbers, or for long distance calls paid for with Orance cards. (Which "home direct" service will accept calls from Europe for 800-numbers served by Orange ?)

We can only hope. Thats probably why the NSFNet's Acceptable Use Policy is widely held to be unconstitutional. The part which says that "no commercial use allowed" restricts speech based on content.

Unlikely. An 800 number costs at rock bottom ten cents a minute, while message rates are usually more like two cents. Even with metered local service, calling direct is considerably cheaper. Note that in New York City, the calls are metered, but local calls are charged one unit (about a dime) per call, no matter how long the call is.

Anyone? Anyone? There has never been a choice of pulse, rotary and tone; just the latter two. According to NYTel, the standard offering is rotary only with a surcharge for tone even though most, if not all, lines can handle tone quite nicely. I intend to call the business office next week and make an attempt to find out if 516-333 is tone enabled which I think it is. I seem to remember that 516-333 was mentioned in the first deployment of SS7 which, at least to me, means that it has either a DMS-100 or a 5ESS switch and is able to handle either touch tone or rotary dialing. I also find it hard to believe that tone isn't deployed in that exchange since tone has been around on Long Island since 1965 or before.

Note that all except 331 are in Nassau County and all are next door so to speak from each other and there are a plethora of businesses and government offices is that area. I don't think that they'd put up with rotary only dialing.

The date when this country code will take effect is unknown. [2] Zanzibar is routed via Tanzania as + 255 54, though the country code 259 is assigned for Zanzibar. [3] St Helena is a code found in service under British Telecom. It may not be an official assignment much as it would be a hack used by BT to provide overseas service to that point. [4] Eritrea separated from Ethiopia in 1993 to become a new nation; until +291 code is in effect, use Ethiopia +251 4. [5] San Marino will be split from Italy's country code (was 39). [6] Trinidad and Tobago are new with country code 296, moving out of North American area code 809 (ie. + 1 809). The date when this country code takes effect is unknown. [7] Aruba got its own country code when it formally became independent of the Netherlands Antilles 1st January 1986. [8] was under Norway [9] Greenland (country code 299) is supposed to be in the part of the world where country codes begin with 3 or 4 (Europe). However, since all those codes are used up, 299 is as close to 3 or 4 as possible. Country codes beginning with 5 are also all gone. [10] Andorra: + 33 628, Monaco: + 33 93 [11] Removed from service as Germany is now one country. New city codes beginning with 3 under country code 49 are now in use for those former east German regions. [12] These are new assignments breaking away from country code 7 (former USSR). Other countries from the CIS or those republics formerly with the Soviet Union, could have new country codes of the form 37x or 9xx soon. [13] Effective 1st October 1993 former Yugoslavia country code 38 was split up into country codes of the form 38x representing the various nations formed from the breakup of Yugoslavia. (Information courtesy teletext of German TV ARD and ZDF as relayed by Thomas Diessel (diessel@informatik.unibw-muenchen.de)).

This is to allow for new land-based services on the INMARSAT network, particularly in North America. 874 will become Atlantic Ocean Region West, while 871 will be for Atlantic Ocean Region East. [23] Reserved for national mobile/maritime uses in various countries [24] By CCITT policy, no more country codes of the 880-889 series are supposed to be assigned until all other country codes beginning with 8 have been taken. 886 for Taiwan is an unofficial code used for access to Taiwan. The "People's Republic of China", on the other hand, has assigned Taiwan access via country code 866 (presumably + 86 6, through China). [25] There is some discussion in CCITT circles that the 800 country code could be established as an international-access toll free service. This is subject to a formal proposal and CCITT approval, however. [26] with the unification of the Yemen republics, it appears that this country code will no longer be needed, as 967 Yemen Arab Republic code will likely take over. In the meantime, the dialing procedures remain as if Yemen were still separate countries, at least until the telephone system can be unified. ------------------------------ From: lincmad@netcom.com (Linc Madison) Subject: Bizarre cordless behavior Organization: NETCOM On-line Communication Services (408 241-9760 guest) Date: Sun, 9 Jan 1994 09:41:51 GMT I have for about four or five months now had a cordless phone, a Southwestern Bell Freedom Fone Model FF1185, ten channels, two lines, "digital security code," etc. I'm mostly happy with it, but there are a couple of problems. (1) There is excessive bounce in the keypad. I had to take the first unit back because I misdialed at least 75% of all attempts. The new unit is not so bad, but still has bad problems with the '2' key. (2) It has ten channels, but doesn't do any sort of "automatic channel selection" or anything like that. By far worst of all, though: (3) Sometimes, when I press the "change channel" button, if my neighbor (in the same apartment building) happens to be using her cordless phone, *she* gets connected to my call while *my* handset is frozen out. I don't know what happens to any call she is on or is attempting. This has happened three times so far. What usually happens is that I hear a click on the line (the other person usually assumes it's my call-waiting) and then the static gets progressively worse. I press "channel" to try to get a better connection, and get dumped. This is EXTREMELY annoying.

Dale <0005517538@mcimail.com> Subject: Dr. Vint Cerf Joins MCI WASHINGTON, Jan. 6 /PRNewswire/ via First! -- MCI today announced Vinton Cerf, well-known in telecommunications and academic circles as a data visionary, has rejoined the company to serve as senior vice president of data architecture for the Data Services Division. Cerf, who was with the company in the early 80's, will be responsible for developing the network architecture of MCI's future data services, as well as the development of a common framework in which data, voice and video services can be delivered to businesses and consumers with equal ease. Cerf, 50, co-developed the computer networking protocol, TCP/IP, widely used in the industry and for communications between the diverse university, government and commercial data networks, known collectively as the Internet. He also has served as president of the Internet Society since 1992. "As we further develop networkMCI, the company's recently announced strategic vision, and the new generation of services that businesses, consumers and governments will want, we need the best minds available to help lead these efforts," said Richard T. Liebhaber, MCI's chief strategy and technology officer. "Vint is one of the leading architects of what we know as public data networking today, as well as a major contributor to the development of technologies needed for a national information infrastructure." "We're very pleased someone like Vint will help MCI drive a new generation of data services as we move into the 21st century," said Liebhaber. Cerf joins MCI from the Corporation for National Research Initiatives (CNRI) where he has served as vice president since 1986, conducting national research efforts on information infrastructure technologies with CNRI's president, Robert E. Kahn (also co-inventor of TCP/IP). Prior to this, Cerf was vice president of MCI Digital Information Services and served as the chief engineer of MCI Mail from 1982 to 1986, working with MCI's J.

I was under the impression that if you order a Network Interface Jack (you have to be sure not to call it a "regular phone jack") the cost is fixed. In particular, that no matter what work turned out to be necessary between the NIJ and the phone company central office, that work was being done for the same fixed $88. If you can describe this a little more fully (in the newsgroup or via email) I would find it most interesting. And if others in New York have been through this exercise and been charged something other than the fixed-price $88 for the NIJ I would be delighted to hear about it.

I think we've found that's not the case. The problem is that cellular airtime costs a lot more than an in-state toll call, the former being on the order of 50 cents per minute, the latter more like 15 cents per minute. > This would have prevented -- or at least lessened -- the New York pager > scam, and can reduce the problems with 976 numbers. Hardly. I know I can call any place in the country for 25 cents per minute or less, except for surcharged numbers. Some of the 212-540 numbers cost $40 for the first minute. The problem isn't free calls vs. non-free calls, it's cheap normal calls vs. expensive abnormal calls. (In New York, for example, no calls are free, since you are charged at least one message unit for every local call.) The 579 prefix costs significantly more to call than any normal Colorado prefix and callers are going to find that out the hard way and complain.

Too often we forget that the history of our civilization is a history of technological progress. Triggering factors result in widespread and substantial change. Mr. Palameta described several such factors in his article. To understand the significance of events occurring today, and their potential significance as triggering factors for tomorrow's progress, we must understand the significance of past events that catalyzed the progress that resulted in today's world. Historically, incremental developments in the communication arts have resulted in revolutionary changes in our society. The invention of language is credited with being a causal factor for the development of society. Paper resulted in a the first indirect communications medium, and allowed the development of modern religions. Medieval church mail services offered the first reliable widespread communications services and Guttenburg's invention of movable type certainly caused revolution- ary change as did the Morse telegraph, Bell's telephone, Marconi's radio, etc. So too, will the changes in computer/telephone/video communications result in changes which we can only speculate about, with the near- certainty that our speculations will be wrong.

With a SLIP link, at a particular moment either you're connected or you aren't. You may be thinking about the distinction between hard-wired and dial-up SLIP. In the latter case, you typically dial into a terminal server, enter the password, then give a SLIP command. The server assigns you an IP address from a pool it has for SLIP users, tells you what it is, and away you go. The better PC TCP/IP SLIP implementations recognize the message with the IP address and automatically update their tables, so it's all pretty much automatic.

A BBS is just a special case of the general class of "multi-user computer systems". Access for remote terminal users of such a system can be provisioned in several ways: 1) If the users are on-site, the system may be constructed with many serial ports, and you may wire each terminal directly to a port dedicated to that terminal. The drawback of this is, that for large systems, serial terminal ports may actually be very expensive (as expensive as high-speed ports, and probably more expensive than the terminals.) 2) Often the terminals are wired to "cluster controllers" that aggregate traffic from a number of terminals (16 is a common number) and feed the aggregated traffic into a high-speed port. The operating system on the server machine must then contain code to unravel the multiplexed data before feeding it into the software driver for the logical ports. 3) If not all of the users are active at the same time, it has been common to attach the terminal to a modem, and attach the modem to a port on the building's PBX, which then routes the calls to a bank of modems which may be attached to ports on the server (as in 1) or on a cluster controller (as in 2). This allow you to get by with a smaller number of ports, and also allows all wiring to be installed by telephone technicians, which traditionally have been easier to find and manage than computer technicians. Also, the PBX already has mechanisms to deal with contention. 4) This technique extends in a simple manner to off-site users: Just attach a few modems to outside lines instead of PBX station ports. You need one outside line with a modem per port, of course. 5) If the callers are far away, you may be able to save by locating the cluster controllers near the users, far from the server system, and attach them to the server by: - leased data lines or - automatic dialers that bring the line up when someone needs service. Generally, if you have a remote building with a cluster, it will be more economical to lease the line. The crossover happens at 2-4 hours per day. If you have 4 to 8 terminals, then it is likely that at any given time at least one will be in use. 6) Some companies have specialized in setting up such remote cluster controllers (called PAD: Packet Assembler/Disassembler) provide them with local dial-in lines with modems, and arranging for shared carriage from these access points to servers in several/many cities over lines leased from the phone companies. These companies (legally called "Value Added Networks") generally use a protocol called X.25 between the cluster controllers and the server hosts. They also provide for connections directly between the servers using the X.25 protocol. The VAN carriers include CompuServe, SprintNet (formerly TELENET), TYMNET, AT&T Accunet, INFONET and many more. With such a hookup, you may be able to use a single high-speed access line to carry traffic originating at hundreds of different remote points. 7) Finally, a whole other group of carriers have sprung up to do the same using a more modern set of protocols called TCP/IP or Internet Protocol. Generally, this is much less expensive than X.25 service, and provides many more features. Principal commercial Internet service providers who offer service throughout the USA include: ANS (Advanced Networks and Services - a partnership including IBM, MCI and the State of Michigan), AlterNET (a service mark of UUNET Technologies), PSI (Performance Systems International of Troy, NY), AT&T, INFONET and SprintNet. (At least the last 3 also offer one-stop international connections.) The special magic of this technology is that the networks are all interconnected, so that your customers can reach you even if they have service from different providers. The company that I work for, is on of many that sells equipment for Internet service. We expect (between all of us) to hook up every school and every public library the US and at least Western Europe in my lifetime. We have a long way to go. To date we have only connected about two million computers, serving about ten million people worldwide.

Perhaps Fred > Goldstein or one of the *real* tech people here will reply. PAT] I have to admit that I don't know much about how real BBSs operate, just how they could be operated. But thanks for the compliment, Pat. BBSs are funny things. I read an article about Channel 1, a huge operation in Cambridge, which services its dozens of incoming lines by a network of dozens of little PCs. They were lined up all over a tiny house. If it were up to me, I'd have a big machine or two ... It's often easier and cheaper to use T1 circuits rather than the 23-24 (30 in Europe) separate analog circuits that it replaces. If your central office is digital (eg., 5ESS or DMS), then a T1 is much easier for the phone company to provide -- it plugs right in to a trunk port. Most large PBXs probably hook up this way now. For modems, though, this isn't always cheaper. You need either a T1 modem (big bucks for a BBS operator; figure $1k/line, from Primary Access or US Robotics) or a channel bank (maybe $5k, but available used) to demulitplex it into analog lines. Of course you could use a PBX instead but a plain old channel bank is lots cheaper since it leaves out the switching function! So I suspect the BBS crowd tends towards big blocks of analog lines. Advantage of moving towards T1: If you're a plain old "kiddiecomms" BBS, then maybe this won't be necessary. But if you use T1, you can not only talk to modems, but talk to ISDN and Switched 56 at a 56 kbps speed. Channel banks, PBXs and T1-modems all support this. Fred R.

Much of what I'm about to say is derived by my research into the question for inclusion into TIA PN2826, what will eventually become TSB-38, a modem testing methodoly description for modems: BTLZ is not a true LZW derivitive, as jim claims. (However, the difference is so minimial that only the truly nitpicking will care.) It is Ziv-Lempel with several additions to permit adaption and to prevent expansion of the data, particularly pre-compressed data. It also has one of the niftiest escape systems I've ever seen. You start with a dictionary pre-filled with the alphabet, and have nine-bit output codes. As data transfer progresses, and the dictionary fills, you expand the size of the output code until you reach the dictionary limit negotiated by both ends. At that point, you start "burning" leaf nodes so that as the characteristics of the data change the LZ tree will change shape to adapt. If a block of compressed data is significantly larger than its uncompressed counterpart, then you enter "transparency mode" and send the uncompressed data. If a subsequent block of compressed data is significantly smaller than its uncompressed counterpart, you then switch to "compression mode". Initally the system is in transparent mode. While in transparent mode, if an escape character is seen, the system sends an escape-in-data sequence like most codes which use a reserved flag character. Unlike the others, though, the escape character definition is CHANGED so that repeated runs of the (original) escape character don't cause a two-fold explosion in the size of the resulting data stream, and a less-than-optimal change to compression mode for that string. For PN2826, we wanted to develop test files which would virtually guarantee one million data bits sent through the signal converter (before HDLC zero- stuffing). So we examines a number of files to determine the compression properties using dictionary sizes common to modems. What I found is that the vast majority of uncompressed files experience a compression ratio (input/output) ranging from 2.5:1 to 3.1:1; the only time I got anywhere near the four-to-one everyone attributes to V.42 bis is when I was transferring B&W line-art in uncompressed TIFF form. (Indeed, with one picture I achieved a 7:1 compression ratio.) Compressed files had ratios which depended greatly on the scheme used to com- press them. LZW-based compressed files showed anywhere from 1.1:1 to 1.4:1 with V.42 bis; a purely random file (generated using the DES algorithm) has a compression ratio of 0.998:1 -- the expansion attributed to the 57 escape-in- data sequences in this 132-kilobyte file. Encrypted compressed files tended to be at exactly 1:1. These figures were developed by running files through a desktop implementation of V.42 bis -- my thanks to Dr. Coleman of Georgia University for the code. This is a straightforward implementation of V.42 bis with a rather wasteful compression prediction algorithm (fill two buckets, throw out the one that's more full) but is simple and surprisingly good at minimizing local expansion. ------------------------------ Date: Sun, 9 Jan 94 15:02 EST From: Christopher Zguris <0004854540@mcimail.com> Subject: Re: Merlin Question In a recent TELECOM Digest post Vince Dugar (vdugar@stortek.stortek. com) wrote: > Why does the Merlin system charge users so much (I forget now, but > it's a lot) to buy a special modem adapter?

Tap pins 4 & 5 with a cable to plug into the modem (or run them to another jack and plug the modem in). The SPST switch is optional, but will come in handy, read on. To use the thing, plug the cord coming from the wall in the "from wall" jack and plug your new cord into the "to phone" jack, then plug that cord into your phone. You're phone should work fine, if it doesn't, disconnect the gizmo and check you're wiring. To actually use the thing, fire up your modem, dial out, and QUICKLY pick up on a line USING the merlin phone. When the modem dials it will dial out through the merlin on whatever line your merlin has selected! The disadvantage to this gizmo over the AT&T rip-off is that you must keep the merlin off-hook while your modem is in use and manually hang up when your modem is done (redialling is impossible- if you want to do that manually dial and redial using the merlin). You will want to set the SPST switch to open so the voice pair disconnected from the merlin, otherwise the modem noise will come through the merlin speaker or handset, and if the handset it used voices and noises will be picked up and sent and screw up your modem communications. I've used a similar setup at 2400 baud, anything above that I can't vouch for. When you're done, flip the SPST switch.

I am interested in finding out a bit > more about the US systems but cant find any FAQ on the subject. The US Digital Cellular scheme (TDMA) was originally conceived to ease the bandwidth requirement for a phone conversation by at least 3 to 1. A 6 to 1 capacity advantage over the regular AMPS service would be achieved if and when acceptable half-rate voice codecs were available. Currently, each caall uses two of the six TDMA time slots. The aim was/is to eventually use only one. The first TDMA phones were to be dual-mode: that is to say that they would function as regular AMPS phones as well. The hope WAS that after 10 to 15 years, the AMPS functionality could be dropped, resulting in more cost effective phones. A monkey wrench has been tossed in the works, however. AFTER the cellular industry chose TDMA as the standard, Qualcomm proposed the use of a different CDMA technology with promises of even greater capacity. Some, but not all carriers joined the Qualcomm camp. The net result is that we now have two digital phone standards. Motorola proposed a new analog system (NAMPS) with a capacity advantage of 3 to 1 over AMPS that many hail as a good intermediate step before full digital cellular implementation. So, now we have FOUR phone "standards". What about ROAMING? Well, it looks like the more expensive DUAL-MODE phones are here to stay. Either of the two digital systems, TDMA or CDMA could have been cost effective with time and further work on the ICs inside the phones. The power-wasting RF duplexers required in AMPS phones for full-duplex operation would not have been needed -- money would be saved and talk time increased. Six times the existing bandwidth was not enough. We got greedy. Don Miller dmiller@crl.com ------------------------------ From: images@netcom.com (David M.

If you join Reach Out World from AT&T for $3 a month, then it seems that there are only two time slots and there is no higher first minute charge. It's quite competitive with MCI now, Friends and Family even taken into account. For example if I specifiy New Zealand as my Selected Country then during off peak times and weekends I get to call *any* number in NZ for 0.68/minute while with MCI and their Friends around the World plan and Friends and Family, I get to call only a maximum of two numbers for $0.66/minute.

In another life, at a super-mini company, we had a subsidiary PBX design company that was designing a terminal/phone combo but the whole thing evaporated during a "rightsizing". I saw one working - real, not a prototype. There was a button on the terminal keypad that would bring up a phone menu and you could click on the option you wanted. Software on the computer could interact with the phone so you could have a Rolodex on-line and touch a number to dial it, record and playback digital messages and record and playback on-line (with a beep). You could then file, mail, etc. the messages. Took lots (and lots) of disk space but we sold disks so what the heck. Used realy cheap off-shore digital handsets - bad but liveable. Probably something like the Newton will solve this. Also, the VCR programming in another thread.

If you get the right hardware, that isn't necessarily true. You could dedicate one line/SLIP connection if you wanted to, but many people don't. Most people dedicate one IP _addresses_ to a SLIP user. That mostly depends on how much you're willing to trust any IP address (for security purposes or otherwise ... like access to a USENET server). > I've heard some talk about so-called 'dynamic' SLIP -- where the SLIP > connection is made, but through a mux or terminal server, allowing the > provider to serve multiple dial-up customers instead of a 1-1 ratio. ... Yes, true. I use Cisco communication servers to do this, but there are many more vendors that provide the same features. Depending on your computer's OS, you might be able to connect a modem into it and server multiple SLIP users. The one thing I'd worry about is that most SLIP servers I've seen can only provide access to the subnet they are in ... so you can only server ~250 (fixed, single user/IP addr) users with one rotary.

Although considered venerable by some, it is also extremely widely used. This book hopes to make sendmail administration not only easy, but fun. Quite a task. Part one of the book is tutorial in nature, starting with background information in chapter one. We are given a brief history and philosophy of sendmail, plus some description of the component parts, and the related Internet RFCs (Request For Comment) and technologies. (RFCs, the name to the contrary, are the descriptions of how Internet functions should work. In a sense, they are the standards of the Internet.) Chapter two gives us some examples of how "subnetworks" of machines within the Internet handle mail among themselves, and introduces routing, very briefly. It takes its tutorial function seriously: there are questions at the end of the chapter for you to think about or try out. The questions get harder in chapter three, and start requiring more knowledge of both UNIX and the RFCs, in order to deal with headers and "envelopes". (Actually, the text is easy. Only the questions are hard.) Chapter four introduces the various related programs that sendmail calls and the functions it performs. So it continues up to chapter fifteen. The tutorial covers the invocation and switches, the configuration file, mail delivery agents, macros, rules, rules and more rules, class macros, options, headers, and miscellaneous topics. Part two deals with administration and management, and runs you through the process of configuring, compiling and installing sendmail. It also has specifics of V8 and IDA, as well as DNS (Domain Name Server). Topics covered include security, the queue, aliases, mailing lists and forwarding logging and statistics. Part three is the reference, and chapters twenty-three to thirty-three list the options for delivery agents; defined, class and database macros; options, headers, the command line and debugging. Finally, seven appendices deal with queue file intervals, obscure error messages, the "define" macros in the confi.h file, the client.cf file from the tutorial, V8 and IDA configuration macros, and a bibliography. Because of the nature of the book, you will find a fair amount of material duplicated (for example between the tutorial on delivery agents, and the reference sections). However, the duplicated material, and the short chaptering make this an excellent reference work overall. The material is generally clear and well laid out. The tutorial section is definitely for the technically advanced: I suspect the authors have a ways to go before many people find sendmail "fun". copyright Robert M.

They are a great combination, as you are even able to turn off call waiting through the three-way calling on an incoming call. Now, the problem is that when I am on a three-way call, my line becomes busy, allowing no calling to come through. I know other people in different areas who can be on a a three-way call and still receive call waiting. What is the reason for this difference? I called Bell of PA, and they said that it just wasn't available in my area. Anyone know? Michael Israeli izzy@netaxs.com [TELECOM Digest Editor's Note: There are two types of 'three-way' calls. If you are in 'consultation' you have pressed the hook, dialed a number and are talking with a third person while leaving the second person on hold. Situations like that will result in a new caller getting a busy signal. If however you have flashed, dialed the third party and gotten him on the line, then flashed again so that the three of you are talking then call waiting should become available once again. At that point if there is a call waiting, flashing will leave your two three way parties (from your outgoing call) on hold unable to speak to each other while you take your new incoming call. The reason a busy signal has to be given to a new arriving call during the early stages of a three way call (when you have flashed, gotten dial tone and brought one additional party on the line but not yet joined that party with your call in pro- gress) is because you only have one flash of the hook available to you and there is a conflict at that point as to whether the flash should cause the newly dialed third party to join your outgoing call or it should cause the whole thing to go on hold while you speak to the newly arrived call waiting. Try getting an actual three way call installed (not just to the beginning 'conference' stage where you talk to a third party and tell him you are attaching him to the call in progress) where you are talking to two parties (both of whom *you originated*) then see if call waiting does not work okay once again. Where there is a conflict between CW and 3WC (because flashing the hook could cause one thing to happen or the other) then 3WC takes priority. The theory is should telco hand you a CW at that point in time does your flash mean you want to accept the new call or connect the other two. Since maybe you do not want that to happen (the two you dialed to be joined together) telco has chosen to block CW for that limited period of time. Let us know.

Hoffman) Subject: Someone Has Tapped My Line - Help Date: Mon, 10 Jan 1994 18:40:12 GMT Organization: Excelsior Computer Services Two hours ago, I heard a clear conversation on my line. I live alone, and have no extensions, so someone else is using my line. I called the phone company to try to get information (on another line) and tried to get information about the call, but they told me that local calls are not recorded. The technician tells me my line is connected to a 5ESS. Am I correct in assuming that the phone company can access that information, but that they're choosing not to? Does anyone else have experience with this, and perhaps advise they can offer? Many thanks. Joel (joel@wam.umd.edu) [TELECOM Digest Editor's Note: One of four things is happening: Assuming the worst, someone did 'borrow' (or is 'borrowing') your line. Telco won't know about that immediatly until/unless a technician or outside plant auditor specifically comes out and looks around. Check your bill when it comes for calls you did not make which appear to be direct- dialed or an unusually high number of local calls which you feel sure you did not make. The second case would be where someone in your area got new service and telco did accidentally put them on your pair of wires due to errors in the outside plant records as to what pairs were available for use, etc. In either case, telco will make the required adjustments in billing and service (who gets which wire pair, etc) when the matter is brought to their attention. In the third case, a very temporary fluke or bug or programming error caused the ESS to misbehave for a few minutes. Again, telco will make required adjustments, but actually catching this while it is happening so that it can be traced and corrected will be difficult. In the last scenario, there may have been 'crosstalk', a condition which occurs when wires get wet or are otherwise quite conducive to each other in the cable or at a junction point in a conduit/underground crawl space in the street, etc. You did not say if you were able to participate in the spurious conversation or not (or if you chose not to). In the first two cases above, you *could* have participated should you chose to do so. In the third and fourth case, it is unlikely you would have been heard by the other people had you chosen to speak up. In the case of crosstalk due to intermittant shorts and grounds on your line due to damaged or wet cable, normally what you hear is several conversations going on at one time, none of which are distinct enough to be understood although one might stand out and have reasonable clarity. It could also be that a phone technician was working in the area on a telephone pole somewhere nearby and chose to make a call to his office using your line. That happens occassionally. In order to make an an effective judgment call on this, we need a bit more history and background. Yes, the numbers dialed on local calls are recorded by the ESS, but it is a mess trying to find the record on the microfilm at the end of the billing cycle and anyway, this may have nothing more than crosstalk or a temporary glitch in the ESS. Followup on this for a couple weeks or so and let us know in more detail exactly what you are hearing if you hear it again; if you can speak to the party 'using your line' etc. PAT] ------------------------------ Date: Mon, 10 Jan 1994 10:15:01 PST From: Les Reeves Subject: Possible Internet Service Scam ---------- Forwarded message ---------- Date: Thu, 06 Jan 1994 10:18:48 -0500 (EST) From: Melinda Massi (MHM0) To: Multiple recipients of list TECHWR-L Subject: warning: possible Internet scam If you are contemplating a private Internet account, read the following and be alert.

Coen" Subject: NYTel/NYNEX Dusts Off Rotary Payphones Organization: Drew University Academic Technology Yup, that's right. The return of the pulse-dial, rotary, bleed to death while dialing 9-1-1 payphone. Some neighborhoods have gotten tired of the drug dealers and the "corner office" by the payphone. Seems that a lot of them use the touch-tone payphones to access the beepers of their associates. So, under pressure from local groups, New Yor..., uh, I mean NYNEX, decided to put in the old rotary payphones. I'm sure it broke their heart to find a use for all this old equipment, and to put the touch tone equipment somewhere else. They apparantly tried this in one or two areas already, and it did cut down on the number of people hanging around by the phones on corners. However, in some of the new areas, touch-tone phones are as close as across the street from the "new" rotary phones. A NYNEX official was shown on the local news (WABC, channel 7) saying that these phones "couldn't" be used to trigger a pager. Gee, and DTMF tone generators are so hard to come by. If they make it hard enough to walk to a different phone, the dealers with half a clue will just pick one up. Hell, it isn't like they don't have telephone-savvy people involved -- look at all the cellphone ID modification going on in NYC. This doesn't stop cellphones, either. They did mention, however, future plans to expand blocking. Currently, a lot of these phones apparantly can't accept incoming calls, and NYNEX is talking about expanding this to prevent calls from going out to pager numbers. I wonder how long it will be before the drug dealers just let themselves into buildings and start attaching new wiring to pairs? A lot of the older buildings have tons of exposed wiring and screw-down connections in the hallways and basements. Seems like they're just expanding the incentive to commit cellular fraud as well. Not that I think it shouldn't be done at all, I just think it isn't going to make that big a difference. [TELECOM Digest Editor's Note: The return to rotary dial plus 'calling card, collect or third party billing after dark' seem to be the two principal ways the neighborhood people are convincing telco to help in the 'war on drugs'. Many payphones in Chicago have the latter option on them, meaning coins are not accepted as payment between about 8 PM and 4 AM daily. This causes a more reliable paper trail to exist should someone want to seek it out and prove a point as to who called whom at what time. A third option, and the one which seems to me to be a little more fair to everyone concerned is to fix the phone for no incoming service, although customers of drug dealers could still make outgoing pages and transmit messages to dealers other than to be called back at the payphone they are using. Everyone seems to love the war on drugs as it is quite profitable for all concerned: telcos, governments, police departments -- all are getting extra money from it.

I stopped at a gas station somewhere in Tennessee or Kentucky for refreshments, refilling, and relief, and noticed something very interesting in a business card holder near the convenience store cash register -- a stack of pre-authorized long distance calling cards. I inquired of the cashier. The cards cost $10 for 20 minutes of long distance, or $20 for 40 minutes of long distance. Instructions on the card indicated a toll-free number you could call that would enable you to see how much your card had left, in minutes. This card is printed on paper (as opposed to plastic), and requires no identification or registration to purchase, since the life of the card is based on your pre-paid purchse. The cashier told me the major selling point, that now, if you lost this card, you were only out the amount left on the card. "Great for travelling!" I didn't buy. (Although it would have been interesting to attempt to call overseas with this card, if it let me.) Scott [TELECOM Digest Editor's Note: Those are called 'Talk Tickets' and they are a bit expensive at 50 cents per minute of domestic use although you can get that down to about 35 cents per minute with quantity pur- chases of the ticket from the wholesalers of same. Yes you can make international calls also but instead of 20 minutes for ten dollars you wind up getting about five minutes. To be a wholesaler of Talk Tickets you plunk down $1850 for $2500 in tickets of assorted denominations. That gets you a 25 percent discount off the 50 cent per minute rate, or about 35 cents per minute of use. If you then resell these to truck stops or convenience stores, etc you split the commission with them by selling them the tickets for around $2200; they in turn sell to their customers at the face value. Western Union also has prepaid calling cards like this at a similar rate. Personally, I prefer the Orange Card with its 25 cent per minute rate and no surcharge.

Date: Mon, 10 Jan 94 10:18:53 EDT I've got a couple of the old-style Bell (WE?) 2500 touch-tone phones that I bought from the Telco after renting them that are having troubles dialing. Some of the row and collumn switches are kinda 'mushy' and make intermittent contact, so I'm not making real Touch-Tones. Is there a way to clean these, tighten the switches, or just buy new TT pads? Any hints on cleaning or pointers to suppliers of the real full-travel (not the newer style hinged button) TT pads would be greatly appreciated!

I will provide you the answers to your questions from an overall and MCI perspective. > 1. Which countries/provinces have SW-56 service and are ISDN capable? Today over 20 countries around the world currently have some level of ISDN service. The number is growing as domestic networks are upgraded and advanced signalling is implemented between the overseas carriers and the domestic US carriers. In most countries, the network operates at a 64 kbps level and is accessed using BRI (2B+D) or PRI (30B+D). 56 kbps connectivity can be achieved with the use of a terminal adapter for rate adaption which is marketed by several companies in the US and overseas. MCI International 64 Service currently provides switched digital connectivity to Canada and most of the European and Pacific Carriers capable of providing the service today. Current MCI Tariffed Countries include: Australia, Belgium, Canada, Denmark, Finland, France, Ireland, Italy, Japan (IDC, ITJ, KDD), New Zealand, Netherlands, Norway, Singapore, Sweden, Switzerland, Taiwan, United Kingdom. Additional countries are planned for 1994. > 2. Here in the US what cities have been converted to ISDN, and who are > still operating at SW-56? Availability depends on the local exchange carrier. There is a document published by Bellcore that lists most of the exchanges that are capable of providing the service. You should contact your local LEC provider or your local MCI representative to assist you with evaluating a specific location in your area since the list changes and either source could provide you with up to date information. > 3. If you know, who are their carriers? Service is provided locally by the US Local Exchange Carriers and interexchange and internationally by the interexchange carriers offering the service. The carriers in-country overseas are the PTTs or ITOs who provide local and/or international service. Please contact your local MCI rep or me by phone at 1-703-903-1033 or fax at 1-703-506-6626 if you have any additional questions.

Using this device ($75) along with distinctive ringing ($6/mo) sounds like a wonderful alternative to having separate lines installed for fax, modem, answering machines, etc. Kinda like a poor man's DID! Anyone have any experience with these devices? Any drawbacks? Bob Rankin (r3@vnet.ibm.com) [TELECOM Digest Editor's Note: The only drawback to distinctive ringing and/or call-waiting is that you still only have one phone line instead of two (or three or four), and as long as there is no possibility two or more of the devices (or human persons) will want to be on the phone at the same time everything is fine. As soon as two people or devices need to be on the phone at the same time, everything falls apart. I can see and justify a single distinctive ringing number so that two things share one line if neither is used a lot. But when you are talking three or four distinctive rings for that many end 'users' to share, unless none of them get any real volume of calls there will always be someone or something getting a busy signal in a conflict with the others.

I am assuming that how is this done is to figure out people's voice mail passwords and then use the transfer feature to get off-site. However, on our voicemail system, you only have the option to transfer to another on-site extension or off-site tie-line (within the corporation, only), and not an actual local or long-distance telco off-site line. Are some PBX's just plain stupid in transfer restrictions, or am I missing something here? Kriston J.

So often, there has to be a compromise between security and user convenience. Then too, sometimes the phreaks manage to get the root password (the code used by the system administrator for system maintainence) and reconfigure the system for themselves. Maybe it did not allow transfers to outside lines until the phreaks worked it over using the root password for entry and programmed it to start doing that. I am reminded of the time that former Digest participant John Higdon called me at home very late one evening on a three-way call with some phreak phriend(s) of his on the line because they wanted to brag and show me how 'someone' (the name(s) of the other person(s) on the line were never given to me) had broken into and looted the voicemail system of a certain long distance carrier which specializes in 900 service. It seems 'someone' had gotten in via the root password and proceeded to rephrase certain prompt messages, replacing what had been there with lewd comments of their own about the carrier's pending bankruptcy. So don't assume the sysadmin left that feature there. Phreaks could have called one night and put it back in then run up quite a phone bill by the time the proprietors found out what had happened.

Shannon's law is, in plaintext, BPS(max) = Bw * log(2)((1+S)/N) That is, take the signal-to-noise ration (adding 1 to signal, so a negative SNR has some information present) and represent it as a power of 2. Multiply by bandwidth (in Hz) and you get BPS. THus if you have a 30 dB (1000) signal to noise ratio, that's 1001/1 which is a smidgen under 2^10. If you have 3000 Hz usable bandwidth that's the 10 times 3000, or around 30000 bps max. It was often said that a phone line couldn't go beyond 26000 bps or so, based on the typical bandwidth and SNR. Today a good clean line is more likely to be digitally switched at 64000 bps, which is well above the Shannon limit (digitization is lossy), but you still get a theoretical limit closer to 40 kbps. Thus V.34, at 28.8 kbps, is pushing the envelope, but still possible. But it won't work on a line that's transcoded down to 32 kbps, or just plain noisy. Note the 300 to 3400 Hz nominal frequency range; the 3400 is a hard filter. Fred R.

Well, I have only two lines, and Illinois Bell managed to screw even _that_ up... When we moved to our new home, we ordered both lines at the same time. But because one is a residential line and the other is a business line they were installed at different times. The residential line went in first, and worked just fine. Two days later, the business line went in. But they wired the business line to the residential circuits, and _disconnected_ the residential line altogether! Calls to the residential line were RNA. I don't get it; they had to add a new drop for the business circuit, so they must have known there were supposed to be two lines working.

Christmas Eve, 1983: record cold temperatures here ... the temperature dropped to 29 *below zero* early Christmas Eve and did not go above zero again for three days. On Christmas, the *high* temperature for the day was something obscene like minus ten degrees. Despite conditions as they were, three friends and myself decided to have our holiday dinner downtown at Berghoff's. On the corner of State and Adams, a big excavation in the street with a truck parked there from the Municipal Water Works. The excavation area was blocked off by street barricades and a trash barrel sitting nearby had been set afire, with three men standing there around the fire warming themselves. In the hole in the street, at least fifteen feet below down into the ground was this black, muddy, gunky looking water swirling around rapidly and therein stood two men in hip boots with water halfway up to their posterior with tools doing their thing to replace an obviously quite broken underground water pipe. Despite the ten or fifteen below zero or whatever -- it had gotten so cold it no longer mattered -- I was fascinated by this and stood there a minute or so peering down into the hole at those two guys, the water swirling around everywhere and them banging away and digging, etc ... Christmas Day in downtown Chicago. One of the men standing by the barrel of burning trash was the foreman; he saw me and said jokingly, "Would you like to give it a go, sir? I've got a tool here for you that's about the right size ... when they come up, you can go on down a bit and see what you think ..." I asked him what those guys got paid and his answer was that 'normally' they get seventeen dollars per hour, ".... but today being Christmas they get *double time and a half* ... and for reasons of safety the union requires two men on the job to look out for each other, so that one doesn't fall down and drown, or have it all cave in him, you know? ... ". The two who had been in the hole apparently got the water flow shut off about that time and climbed up to the street and headed right to the fire to warm themselves. They passed among themselves a bottle which did not appear to contain iced tea and the foreman invited me to share with them but I declined and went inside Berghoff's to join my friends. When we came out nearly two hours later full of turkey and stuffings and a few drinks of our own, all five of the water works crew were down in the hole installing a new section of pipe, slopping around through the now nearly frozen mud. Outside utility workers are marvelous people. Does anyone remember when the two AT&T workers were killed in an accident in the Rocky Mountains in January several years ago? They had volunteered to go out to a very desolate area and replace a downed aerial cable that provided telephone service to a little town. Due to very icy, very hazardous conditions their vehicle skidded and overturned; they were killed. It happens, and it t'aint funny.

I am sure the person posting this is well-intended, but I fear that through inadvertence the phrasing used may make people buy wire other than the stuff they wanted to buy. Let's define four colors - R G Y B - and with that, here is a typical so-called "quad" wire. R G Y B And the point is, you could cut the wire anywhere along its length, and you would see the same cross section, differing only in that all four wires may have rotated, e.g. Y R B G but, as you will appreciate, the relative configuration remains the same, R has Y to one side and G to the other, for example. This is Bad Wire For Two-Line Use. It is the cloverleaf type wire mentioned above. Many Readers Have Reported Cross-Talk With Such Wire. Now let's define four numbers, corresponding to color codes as follows: 1 - white with blue stripe 2 - blue with white stripe 3 - white with orange stripe 4 - orange with white stripe These numbers are arbitrary -- they are only meaningful in the following diagrams. 1 2 3 4 This is one typical configuration for "twisted pair" wire, which is what you *should* use for two-line (or more-line) work. At points along the way you may find any of these: 2 1 4 3 or 1 2 4 3 or 2 1 3 4 The main point, as you will have guessed, is that if you stripped off the outer jacket of the cable for some length, you will find 1 and 2 twisted around each other, and 3 and 4 twisted around each other. Often, indeed almost always, this kind of wire has an outer jacket that is of constant thickness. It has a cylindrical hollowness that contains the twisted pairs. Quad wire, on the other hand, typically fills the spaces between the wires, so that when you strip off the jacket it has a cloverleaf- shaped hollowness. For two-line use, don't buy quad. Buy twisted pair. Usually you can recognize twisted pair phone wire from the use of the striped color codes, such as blue with a white stripe etc. Usually you can recognize quad wire from the use of the R G Y B color codes.

In light of NY Telephone's (now NYNEX) use of the quad wire, yet consistently not using it for two-line phones, is probably due to the fact that they'd rather not rewire a building with faulty cabling and would rather use the second pair for both as a backup and as a reinforcing agent to make the wire strong enough not to break as easily as two-lead wire can.

Well, actually, I got mine because my cable company delivers scrambled signal to my house. The chintzy plastic box they rent me as a decoder is able to be controlled via IFR. Which is a darn good thing, because the VCR it is attached to must be tuned to channel 3 all the time if it wants to see any signal at all. VCRPlus is able to handle this situation. I give it codes and leave my VCR turned off and with tape. When it's time to tape, the VCRPlus unit changes channels on the cable box, turns on the VCR, and starts taping. When the programmed time elapses, it stops and turns off the VCR. Once in a while, I need to run a little program I got from the net a while back, to manually generate a VCRPlus code, when I want to tape something from a local station which is not listed in TV Guide. I assure you, none of my VCR clocks blink. Perhaps you should consider broadening your somewhat patronizing definition of whom the product is intended for? John T.

Well, in a word, no. It will mean that those of us who have been tying up a trunk for six hours at the same price as a 30-second call will have to stary paying for the privilege -- though I wouldn't be terribly surprised to see some alternative local loop providers selling a "flat-rate"-type service to people who are priced out of the market by the LEC's. As it is, I probably burn up seven or eight hours a month of modem time, and virtuaally all of it is long-disatance anyway. Considering that I can do ~18kb/s with a Telebit 3000, I'm probably saving money compared with using PC Pursuit or some similar service. One of the big reasons that long distance rates seem to "bottom out" somewhere in the 10 cents/minute rate, even for the most humongous customers is that the LD carriers have to pay most of that to the LEC for the local loop. Perhaps as the RBOCs are able to recoup something for those millions of unbillable hours of local connect time, this will ease up. > Of course, the biggies (Compu$erve, Plodigy, etc.) will have 800 > numbers and just pass the cost along, but one might expect amateur > BBSs, SLIPs, and the like to become much less popular.

If an employee is worth telecommuting, even a $4/hour connection charge is fairly minor in the face of, say, a $65,000 salary/benefits package. Even if you get charged that for eight hours a day, it's minor. Most employees who would best benefit from telecommuting are the ones who are well into long-distance calling areas. And who knows -- I don't follow ISDN or related services too closely, but it (and similar services) will become more widely available as the cost of bandwidth falls. Keeping the local connection price artificially low is a disincentive for LEC's to provide higher capacity and better services. > True, TANSTAAFL still applies and I suppose metering is inevitable > particularly since it is both cheap and desirable for the Telcos.

Flat rate might mean two things -- local calls never cost anything, or local calls cost one message unit no matter how long you are connected. For most phone exchanges in New York state, residence customers get the latter, not the former. Only a relatively small number of exchanges in NY state have true flat rate, where all local calls never cost anything. In NY Telephone's service area (most of NY State) nearly all business service (no distinction made between large or small businesses) is charged so that lengthy local calls cost more than brief ones. > Here are the exchanges in the 33X series for Area Code 516: > 0 1 2 3 4 5 6 7 8 9 > ------------------------------------------------------------- > 33X | |PtJef|GdnCy|<----Westbury--->|Hksvl|GdnCy|Wstby| | > Code: PtJef - Port Jefferson; Hksvl - Hicksville (a small tale here); > GdnCy - Garden City. > Note that all except 331 are in Nassau County and all are next door so > to speak from each other and there are a plethora of businesses and > government offices is that area. I don't think that they'd put up > with rotary only dialing. I find that in general the numerical nearness of telephone exchange numbers has little or no correlation with geographical nearness. I suggest that it would have even less correlation with central office equipment types. By this I mean that while you will sometimes see a "run" of exchange numbers that are clearly closely related (e.g. 333, 334, 335) once the "run" has a break (e.g. from 336 to 337) then I suggest that there is probably no correlation of geographic areas and no particular correlation of central office equipment types. The 337 wires fan out from one building to cover Garden City, while the 336 wires fan out from a *different building* to cover Hicksville. Once we appreciate that they are different buildings, we can see that there is no particular reason to assume anything in common about the type of equipment inside.

In article MAARUF ALI, writes: > Could someone please tell me how to phone US 0800 numbers from the UK? Several previous replies suggested AT&T's USA Direct Service, but stated that the service could only be used to call AT&T-serviced "800" numbers. THERE IS NO LONGER ANY SUCH REQUIREMENT. AT&T previously filed a tariff, allowing the Service to pass "800" calls to the local exchange carrier (serving whatever "gateway city" is processing the USA Direct traffic), for subsequent routing to the appropriate long distance (interexchange) carrier. Generally, then, the following three requirements are necessary to complete a call via AT&T's USA Direct Service, to a USA "800" number: 1. There must be USA Direct access for the country you're in. This is usually a toll-free access telephone number. Alternatively, in a few countries, you may use special public telephones. In even fewer countries, both access methods exist. (To learn more about USA Direct, from outside of the USA, call collect: +1 412 553 7458.) 2. You must be calling an "800" number which does not have a geographic restriction against calls from the "gateway city" (in the USA) which serves USA Direct traffic from the country you're calling from. (This is unlikely, but possible. Most USA "800" numbers have no such restriction.) 3. You must have an AT&T Calling Card to which the cost of the international segment of the call may be billed. International customers holding an acceptable bank credit card may request an application for an AT&T Calling Card by calling (collect): +1 816 654 6004. It's my impression that AT&T will not, due to international agreements, knowingly complete USA Direct calls to Canadian or Carribean numbers. Ideally, with North America's increased awareness on global trading, American businesses will, over time, become better educated on international telecommunications issues. In the mean time, I hope the above will be helpful to those businesses which, due to their specialized needs, for example, must trade with American corporations in spite of any current naivete.

Another is that the copmpany is too small to handle its own marketing and has "outsourced" the order business to a mass order taking (is there a one word description?) organization. In this case, the 800 number may be the only way the order-taker knows which company's name to answer with. (Remember when you were supposed to ask for a particular "operator number" and this told the outsourcer which company to respond as). Thus an "800 only" number is a flag to me that 1) The company has probably outsourced the order system and 2) They do not have anyone at their office to take orders. At one time I used to be amazed at the "one-man" operations operating out of their home with giant advertising.

PAT] I just saw a Ginzu-knife commercial on TV advertising a do-it-yourself device. What this seems to be is a flat metal headset that goes on your head but has absolutely no electronics in it. Instead, one of the "earpieces" is a round metal plate with a Velcro patch on it. You get another adhesive Velcro patch which goes onto the back side of a regular cordless phone. When you put on the "headset" and attach the two Velcro pads together, you essentially get hands-free operation and mobility -- which is what the original poster wanted. (Of course, you could use this with a wireline phone too, if all you want is hands-free operation and not mobility.) I have no idea how well it works or how comfortable it is. If you already have a cordless phone, this alternative will cost you $19.95, as opposed to the $399.95 cordless headset from Hello Direct. ------------------------------ From: jjc+@pitt.edu (Jeffrey J.

Case in point: My sister was in a situation with a former *friend* who was harassing her (phone calls, stalking, rocks through windows, etc.), so she started by getting a restraining order and an unlisted phone number. The phone was quiet for about two weeks, but the calls started again. At this point she noticed that she hadn't received a phone bill that month. Well, it turns out that she probably did, but her former *friend* probably had stolen it from her mailbox (yes, that's a crime, but try proving it w/o witnesses!) and read her new phone number right off the bill. So she paid to get another new unlisted phone number. Her former *friend* was then arrested on a charge of violating the restraining order, and while in the police department, her former *friend* read her new phone number off the police report. So she paid to get another new unlisted phone number. This scenario probably would have continued, but fortunately this was college, and she graduated soon thereafter and left that town forever.

At first glance, the ROLM phonemail (voice mail) system is extremely difficult to master at first, especially if you DON'T have a ROLMphone. The ROLMphones have templates on them with most of the phonemail commands like delete, save, listen, record, skip, etc., plus extra keys which on our phones are mostly inactive. If you DON'T have a ROLM phone, you can still use the DTMF touch-tones and flash feature of your existing phone, but I weep for you. The ROLM phones seem to use a digital-style link between the PBX and the phone itself for the special buttons and fancy blinking lights, but it will still accept that white-bread DTMF fone with flash capability you may have floating around. At least on our system, which was put into full operation sometime in the spring and early summer of '93, the phonemail prompts are very descriptive, but can drive a new user crazy. Follow the tutorials in the user manuals. I, unfortunately, didn't have that luxury until after I cut my teeth on it. Be SURE to beg, borrow, or steal one of the flip-chart-style help indices that stick to your phone. It gives you all the commands in a handy flip-chart format. Disclaimer: I am not an employee or representative of ROLM, who seems to make very good PBX's and phones. At least better than the Northern Telecom PBX's I've been a captive customer of before.

"The Sprint name is synonymous with 'fiber-optic network' and 'technology leadership,'" said Dave Schmieg, president of Sprint's Consumer Services Group. "All of our products and services are offered via the world's first and still only all-digital, fiber-optic network. The pin-drop quality of our voice and data transmission is unsurpassed in the industry. Sprint's state-of-the-art network allows us to again pre-empt the competition and be first in the market with an exciting new product for our customers -- the Voice FONCARD." The Voice FONCARD is available only through Sprint Priority Gold(SM), a package of services also announced today by Sprint. Instead of punching in phone numbers and authorization codes, customers can let their voices do the dialing: "Call mother," "Call pediatrician," or "Call stockbroker." Speak it, and the Sprint network will do the rest. "Once you've learned a single 800 access number, you won't need to pull a calling card out of your wallet, look up phone numbers, or punch in any more digits," said Schmieg. "Give your fingers a rest. The network is interested only in hearing your voice. No voice can be heard truer than on Sprint." Schmieg continued, "Everybody's voice is different so this technology offers built-in fraud protection. The voice-matching process is secure enough to ensure authenticity, but flexible enough to allow for slight variations in a caller's voice due to illness or fatigue." Here's how to place a call using the Voice FONCARD: o dial the 800 access number; o speak the Voice FONCARD number, which is the card holder's Social Security number, preceded by one digit (for added protection, the Social Security number is not printed on the card); o then direct the system to place the call by saying, for example, "call home." The system recognizes the security code and verifies the voice print, which has been pre-registered, before automatically dialing the requested number. Users of the Voice FONCARD can register up to 10 spoken speed dials with the system, from "call home" to "call doctor." The Voice FONCARD can be customized to fit specific calling needs, whether for frequently dialed numbers, or hard-to-remember numbers. Voice FONCARD users are not limited to the spoken speed-dial list, and may manually dial any desired number. "Sprint's Voice FONCARD represents the cutting edge of technology," said Schmieg. "We're using that technology to provide convenient and easy-to-use communications tools for our customers and paving the way for voice activation to become a worldwide means of communication." The Voice FONCARD is being supported with national advertising featuring the voices of celebrities such as Candice Bergen, Sprint spokesperson and Emmy-award winning actress from the hit TV show "Murphy Brown;" Steve Young, San Francisco 49ers quarterback; Don Shula, the "winningest" NFL coach of all time; Beverly Sills, opera singer, and Harry Caray, voice of the Chicago Cubs. In addition to the Voice FONCARD, Sprint Priority Gold customers receive, for a low $5.00 monthly fee, benefits that make long distance calling easier, including: o Automatic savings on residential dial-1 calling. The Most(R), Sprint's lead residential calling plan, saves customers up to 36 percent each month on domestic calls. The Most WORLDWIDE(SM), Sprint's international calling plan, saves customers up to 36 percent each month on domestic calls and up to 20 percent on international calls. o Sprint Advisor(SM). Sprint regularly reviews customer accounts to ensure they are getting the best value for their money. Sprint will notify the customer of other Sprint calling plans that will help them save money. o Sprint Priority Rewards. With every call, customers earn points toward merchandise, free nights at Marriott Hotels, discounts on United Airline tickets, free calling and more. o Sprint Priority Gold customer service. Sprint provides a service center dedicated solely to Sprint Priority Gold customers. Sprint is the first major long distance company to make calling easier by offering voice-activated technology, one of many technological innovations from Sprint. Sprint is a diversified international telecommunications company with more than $10 billion in annual revenues and the United States' only nationwide all-digital, fiber-optic network. Its divisions provide global long distance voice, data and video products and services, local telephone services to more than 6 million subscriber lines in 19 states, and cellular operations that serve 42 metropolitan markets and more than 50 rural service areas. ------------------------------ From: nagle@netcom.com (John Nagle) Subject: Re: Unique Idea: Error Message for TDDs Organization: NETCOM On-line Communication Services (408 241-9760 guest) Date: Tue, 11 Jan 1994 17:50:33 GMT Paul Robinson writes: > By accident I found something new and unusual. > "We're sorry, because of an area code change, your call > cannot be completed as dialed.

Is this something which will become standard in the US, perhaps to comply with the ADA? If so, consideration should be given to supporting it in modems and modem programs, so computers can use that data. TDD is just 5-level Baudot at 45.45 baud, sent half-duplex using the (I think) "Originate" tone pair of a 103A type modem. Most older modems, and some newer ones, can be coerced into using this mode.

"D station" quad wire commonly used for household telephone wiring does not have the individual pairs twisted inside the jacket. This causes it to have very poor crosstalk performance.

Everyone seems to think that multiplexing lines across T1's is the greatest thing since sliced bread. However, even the most cut-rate companies in the Chicago area charge $700-800/month for a T1 line. At 24 simulated POTS lines/T1, this is about $30/line/month. Not even Ameritech is so evil as to charge $30/line/month -- we pay about $15/line/month. Add in the $5K for muxes and the fact that you almost always have to use proprietary (read as expensive/poor selection) modem cards, T1's really are a bad deal.

Where > can I get additional information on "radio modems"? The general technology you need is called packet radio. There are several rec. groups dedicated to it, they can be of much help. In general, you use a pair (one at each end) of special radio "modems" called TNC's, or Terminal Node Controllers. These are different from a standard modem, in that they have hardware that actually assembles the packets (chunks of data) and then sends it to the modem chip. The TNC connects to a serial port on the computer, and to the mic jack on the radio. The radio needs to be of a suitable type for the ranges involved, and if needed, you need to be licensed. Then, using a special (generally easy to get shareware) communications software (I like one called YAPP, for yet another packet protocol), the two machines, radios, etc call each other.

WALNUT CREEK, Calif.--(BUSINESS WIRE) -- PacTel Cellular today announced plans to invest nearly $250 million over the next five years to build its Code Division Multiple Access (CDMA) digital cellular networks in California and Georgia. The company will launch its first commercial CDMA system in Los Angeles in early 1995. Digital cellular technology offers a platform for introducing many important new wireless services for business and consumers: text messaging, in-building coverage, voice mail notification, data communications, fax, and one-number calling. The advent of CDMA will help fuel the growth of personal communications services, as digital systems provide the capacity to serve the mass market and enable new customers to take advantage of the benefits of tetherless communications. As part of its digital deployment plans, PacTel Cellular announced it has signed a definitive agreement with Motorola to purchase CDMA network infastructure equipment for use in the greater Los Angeles area. The value of the Los Angeles contract is initially about $70 million and could reach $130 million by the year 2000. In addition to Los Angeles, PacTel plans to deploy CDMA in San Diego, Sacramento and Atlanta over the next three years, using Motorola infrastructure equipment. "We're committed to maintaining our strong leadership position in the wireless industry," said Sam Ginn, chairman and chief executive officer of PacTel Corporation. "By investing in this new digital technology, we're demonstrating our intent to build a high-quality cellular network that will meet our customers' needs cost-effectively. Our current investment in CDMA will allow us to reduce our cost structure significantly in the future." "Although new players are entering the personal communications marketplace, we don't believe their services will provide any advantages over our digital cellular technology," added Lee Cox, president and chief operating officer of PacTel Corporation. "Given our 10 years of experience building, operating and marketing cellular service in L.A. -- one of the country's most demanding markets -- we feel that we're well positioned to compete successfully against the new entrants." PacTel will begin installing the Motorola equipment in early 1994, with pre-commercial service slated to begin by mid-year. The company intends to conduct comprehensive testing before launching commercial service. By the end of 1995, the digital network will completely cover PacTel's Los Angeles market, a region of nearly 11,000 square miles, making this the largest CDMA infastructure deployment contract announced to date. "Motorola is pleased to have won this commercial contract to deploy CDMA throughout an entire city -- one of the largest in the United States," said Jack Scanlon, senior vice president and general manager, Motorola Cellular Infastructure Group. "We are confident Motorola's CDMA technology will provide the basis for significant improvements in call quality and new calling services for PacTel customers. CDMA will redefine cellular service during the second half of the '90s." "We welcome Motorola's strong commitment to CDMA technology," said Craig Farrill, vice president of technology planning and development for PacTel Corporation. "Based on our work together over the past four years, we feel confident that Motorola will support our goal of delivering a technically superior network, quickly and economically." "By combining CDMA digital technology with Motorola's advanced networking capabilities, we'll be able to provide cellular customers with an array of highly portable personal communications services," Farrill explained. "For example, customers will have control over how and when their calls reach them, whether they're in their home markets or traveling." Under the agreement, PacTel will purchase Motorola's new SC(TM)9600 digital base stations, cellular base station controllers, and digital switching platforms manufactured for Motorola by DSC Communications Corporation. Due to CDMA's dramatic capacity increases, the Los Angeles network eventually will be able to serve about four million customers, or more than 25 percent of the region's entire population of 15 million. PacTel will offer dual-mode phones which can operate on its new digital network as well as the existing analog system, providing customers with a smooth transition to CDMA technology. During the pre-commercial phase in Los Angeles, PacTel plans to use Motorola's prototype and pre-commercial dual-mode CDMA handsets. PacTel previously announced agreements to purchase a total of 50,000 dual-mode phones from OKI telecom (30,000 phones), Hyundai (10,000 phones) and Maxon (10,000 phones). The company expects to complete similar CDMA agreements with other subscriber equipment manufacturers in the near future. Some of PacTel's wireless competitors in Los Angeles have recently deployed other forms of digital technology. "We know from our ongoing market research that customers place the highest priority on voice quality and network coverage," commented Cox. "Since we're more interested in offering the best digital technology than being first to market, we've chosen a carefully managed process of testing and refining our network. We think it's clearly worth the wait for CDMA and the long-term benefits it offers." To expand its customers' cellular coverage when they're traveling in the United States and Canada, PacTel is a member of MobiLink (SM), an alliance of 15 cellular companies. MobiLink has set common service standards to ensure consistent cellular quality and service nationwide. The MobiLink national network already reaches nearly 85% of the population of the United States and Canada and expects to cover virtually all of North America through licensing agreements. With MobiLink, PacTel Cellular customers using dual-mode CDMA phones will enjoy nationwide coverage with a single handset. In 1989 PacTel was the first cellular carrier to field test CDMA, which is based on technology developed to provide secure communications for the military. Its wideband channel, advanced receiver technology and sophisticated encoding scheme result in a signal that is highly resistant to interference and eavesdropping. Some of CDMA's advantages over existing analog technology include improved voice quality, broader coverage, enhanced privacy, capacity increases of at least tenfold, and the potential for expanded wireless data and messaging services. Since 1990, PacTel and Motorola have been testing CDMA using PacTel's San Diego network in conjunction with Qualcomm Inc., and a group of other carriers. PacTel Corporation, based in Walnut Creek, operates cellular, paging, vehicle location and international wireless ventures in a number of the world's best markets. PacTel Corporation and PacTel Cellular are subsidiaries of Pacific Telesis Group, a worldwide diversified telecommunications corporation based in San Francisco. On December 3, following the third-largest initial public offering in U.S. history, PacTel Corporation began trading on the New York and Pacific Stock Exchanges under the symbol PTW. Subject to final approval from the Pacific Telesis board of directors and certain other conditions, Pacific Telesis plans to spin off PacTel as a completely independent company in the first half of 1994. Motorola is one of the world's leading providers of wireless communications and electronic equipment, systems, components and services for worldwide markets. Products include two-way radios, pages, personal communications systems, cellular telephones and systems, semiconductors, defense and aerospace electronics, automobile and industrial electronics, computers, data communications and information processing and handling equipment. Sales in 1992 were $13.3 billion.

According to the 800 number posted recently on this forum, my switch is set up to handle ISDN! A friend who is an authorized Pac*Bell digital services reseller arranged for some techs to come out and do a site survey; this means they'll check the line loss to see whether the existing copper can support ISDN without an additional signal boost. According to my friend, ISDN is currently tarriffed in California under a provisional business class of service, which means that I'll pay probably a little more per month ($35, I recall) than I might if there were an ISDN available under a residential service plan. Nonetheless, it does seem quite reasonable given the potential benefits. The ISDN they're selling will be two B and one D channels.

Back in my old paper files somewhere I have a product-test article from an American computer magazine about a LAN system that did just that (I can't find it). From memory, the author said that the system worked quite well at a relatively low speed, but was limited in distance to the first transformer in the street. It seems to me that today, with adaptive filtering and the ability to handle higher frequences -- plus digital echo-cancellation, etc. -- these systems may be worth examining again. You'd need a bit of collision detection, but for small businesses and home use this might be the cheap way to tie together a few PCs and a printer. A Sydney, Australia, company called TCG Pty Ltd (fax +612 319 3629) makes a simple one-way power-line-carried system called 'ILID' which uses the data control of light circuits in supermarkets to transmit optical signals to addressable shelf displays. The transmitter sends out data packets through the power lines, the light tubes in the store then translate these to optical packets, which are then received by small photocell-powered LCD screen displays on the shelves. It gives them a simple way to update prices. ------------------------------ From: groeneveld@cmi.tno.nl (Jim Groeneveld CMI-TNO Leiden NL) Subject: Internet <- > FIDOnet Mail/File Transfer Date: Wed, 12 Jan 94 10:50:18 MET I found your address in mailings concerning the subject Internet<-> FIDOnet. So that's why I'm addressing you presently with some Q's. I would like to have some information on transferring mail between Internet/Bitnet and FIDOnet: 1. are there other, more direct forms of addressing a mail from FIDOnet to Internet and Bitnet? I know the form "uucp at number" with the first separated message line "To: internet_address". With this form of addressing it is not possible for a point (using Dutchie) to add the addressee to his/her node list. Only uucp gets added (the first time). In the Dutchie documentation there is a remark in which the form "uucp#internet_address" is stated. Is that a valid form? It would allow different internet addresses being added to a FIDOnet node list at a point. 2. With the form "uucp at number" what gateway FIDOnet numbers are available in the US and Europe? Must they all be called "uucp"? 3. What gateway(s) is/are used when sending from Internet/Bitnet to FIDOnet using the address form First.Last@Pp.Ff.Nn.Zz.FIDOnet.org ? 4. What happens if the Pp.Ff.Nn.Zz do not match First.Last? 5. What is the average transfer time from sender to recipient? A day? 6. How should (binary) files be transferred? UUEncoded or so? 7. Are FIDOnet users (especially points) able to order files from the SIMTEL collection or other public file systems? If yes, how? I hope this doesn't bother you too much, Regards, Y.

About two years ago, I asked telecom readers for information about local rates, because I had the same fear. My results indicated that flat-rate local calling is readily available everywhere.

I rather doubt it; residential flat rate local calling is justified as a giveaway of excess capacity that must be there in order to serve the business community during "prime time". Alternate providers would tend to establish rate structures that discourage residential customers so that they don't have to build local plant to serve the low-volume customers. > One of the big reasons that long distance rates seem to "bottom out" > somewhere in the 10 cents/minute rate, even for the most humongous > customers is that the LD carriers have to pay most of that to the LEC > for the local loop.

There is no inherent reason that a telco under rate cap (de)regulation will lower the access charges charged to IXCs just because they obtain a new revenue stream somewhere else. On the other hand, a rational rate structure would charge the IXC exactly the same as a local customer for what is essentially a local call at each end of the long-distance call. >> threat would be to the infant telecommuting industry and the home >> office which relies on unlimited local service and the best means for >> achieving the Clinton/Gore "20% reduction in commuting" would go up in >> smoke. > If an employee is worth telecommuting, even a $4/hour connection > charge is fairly minor in the face of, say, a $65,000 salary/benefits > package. Even if you get charged that for eight hours a day, it's minor. > Most employees who would best benefit from telecommuting are the ones > who are well into long-distance calling areas. Many telecommuters will have a local call to an internet carrier's local Point Of Presence. Eight hours at $4/hour is $32 a day. This is at least the equivalent of another hour's salary. Hardly negligible. >> only advantage that I can see for the consumer would be that with >> metered service, the subscriber would have a right to a call detail >> listing the individual calls by called number, time, and duration. Hahahaha hahaha ha ha ... he ho hummmm ... Here in Denmark, local calls have been metered for many, many years -- by the pulse method. Itemized billing is NOT available, and there would be an uproar from office workers -- on privacy grounds -- if the telco were to start itemizing bills. Itemized billing, like flat rate local calling -- is a feature of the American telephone system; it has ended up that way mostly by accident. Certainly there is no logic that says subscribers have the right to an itemized bill. (There may, however, in many jurisdictions be a PUC regulation saying so.)

I know this wouldn't work in Sweden, since we have some law about keeping personal data on automatically readable media (as the phone- book wouldn't be, with OCR ...).

The youth, who as a young offender can not be identified, allegedly used a computer to gain access to customers' voice mail boxes. The teen would change the greetings in the voice mailboxes, and the new greetings were used to approve calls billed to the Rogers Cantel Inc. network. About $200,000 worth of calls were billed to a single phone number over a 17-day period. Cantel blames Bell Canada's new automated long-distance billing service, and is fighting with the phone company over who should pay for the losses. Since the alleged thefts last spring and fall, Cantel has started offering customers a service that will keep their cellular phones from accepting third-party bills. A industry analyst estimated that long-distance fraud costs North American companies $2 billion a year, much of it by hackers who gain access to telephone networks by breaking access codes. (END) Geez, to ring-up a $500,000 cellphone bill he must have been on the phone for AT LEAST a couple of hours!!! He'll probably end-up counter-suing the cellular carrier for giving him a brain tumor, or something ...

Stealing voicemail passwords and redirector access codes is trivially easy if: - Any of the system users have cellphones; - They aren't directed, in the strongest terms, to NEVER use secured system features from cellphone; Cordless phones are also a risk, although a smaller one.

I thought I'd post again ... Our company has the main facility in Ventura, CA, and we have smaller sites throughout California. Right now, we're just using regular phone lines to connect to these facilities for voice. For data, there's a T1 going from the Ventura site to the long distance carrier POP, and they run 56Kb circuits to each of the remote locations. We're currently using only 7 channels on the T1, and expect to have a total of 12 in use by the end of the year. I'd like to know how complicated it'd be to use the remaining 12 channels for to route voice calls to our remote sites. Ideally, the extensions at the remote sites would look like regular extensions to everyone else in the network. Some technical details ... The main facility has an AT&T System 75 switch. The remote sites have their own switches, though not all of them have the same model (or brand, for that matter). One of the facilities doesn't even have a switch, just three lines in a rotary (our smallest site). Thanks!

To be more specific: I have two LANs that are interconnected via bridges and T1/FT1 WAN links. I have a PC on the remote LAN that has an unused serial port ("COM2"). I want to be able to use telnet from a PC on my local LAN to connect to that that port so that I can connect to the (9600 bps async) console port of a non-ip device located near that PC, in this example a smart CSU. In effect we would be making the remote PC a small terminal server. It has been suggested to me that there may be software solutions to this. Ultimately I want to be able to do this for Macs and unix stations, too, but for right now I would be pleased with a solution for PCs. Any help or pointers to resources would be greatly appreciated.

Really ugly looking. They had placed on each side or the doors these huge, blue NYNEX logos. Amazingly ugly looking!

The preface describes it as an industry primer. A number of other "Basics Books" have sprung from it on specialized topics, and this new version is the "basic" book of the new series. In general terms, the book does reasonably well as a primer. The tone is light, with a fair bit of humour thrown in, as well as cartoon illustrations of many points. I doubt, however, that completely non-technical managers who need to get a minimal background overview of data communications will be entirely comfortable with it. Although it makes fun of other texts as being written from the perspective of someone with three degrees in computer science, it is entirely clear, despite any efforts taken to modify the fact, that this was written by engineers. At the same time, there are occasional problems with the material presented. While there are no overt errors, there are very possible sources of confusion, as when the discussion of"smart" and "dumb" terminals seems to relate the two classes to block versus character based transmission. The OSI model of data communications layers is discussed under the topic of X.25 and packet switching, and may contribute to a misunderstanding of the purpose of a layered model. The strongest emphasis is on "point-to-point" networking--in other words, the connection of terminals or computers in related, but geographically dispersed, offices. However, as a short and reasonably fundamental introduction to data communications, it has its uses. copyright Robert M.

Senior citizens (and those who someday expect > to BE senior citizens) are invited to participate. > Access the OTA TELEFORUM off the NPTN Special Projects on the main > menu and join in this rather interesting application of teledemocracy > at work ... I entered the forum and was able to pull the following "about" paragraphs. Two things to note: Apparently the "teleforums" are available on five popular Freenet systems (the ones in Buffalo, NY; Cleveland, OH; Denver, CO; Tallahassee, FL; and Youngstown, OH) and I would assume you need to have an account on one of those systems in order to participate (Internet users can telnet to all these systems, and they are accessible from many Gopher systems as well). Also, it appears that the Social Security Administration is considering making some or all of their services available via the Internet. This could be good or bad depending on whether proper attention is paid to privacy. However, one thing that personally disturbs me is that they are apparently at least considering elimination of mailing of checks to individuals, in favor of disbursements via "Electronic Fund Transfers or Electronic Benefit Transfers." My initial gut reaction to that is that this could have some real negative effects on privacy and individual liberty, because it would in effect force people to have an account at some financial institution in order to receive benefits. I won't comment further on that now because I haven't really thought about all the implications of this yet. Anyway, here's what I was able to pull off of Youngstown Freenet: ABOUT THE OTA TELEFORUMS Over the next five years the Social Security Administration (SSA) intends to spend about $1.1 billion on information systems procurement and modernization. Critics of SSA -- most notably the General Accounting Office -- say that SSA does not have a solid justification for this huge investment. That they have not shown that it will result in improved service delivery, or an improved work environment. To help settle this dispute both agencies turned to the Congressional Office of Technology Assessment (OTA) to do a study of the issue. The OTA, in turn, has asked the National Public Telecomputing Network (NPTN) to set-up an electronic forum which would allow YOU to express your opinions on the matter. Here's how it works ... When you enter the TeleForums you will be able to select any (or all) of four issues to comment upon. The issues have to do with: 1) SOCIAL SECURITY AND CUSTOMER INTERACTION 2) NETWORK ACCESS TO BENEFIT FILING SERVICES 3) DISTRIBUTION OF BENEFITS 4) YOUR GENERAL SATISFACTION WITH THE SSA You then choose the issue you want to examine and READ THE FILE CALLED "README." This file will contain a summary of the issue and the kind of things we would like the discussions to focus on. Each of these forums will be running simultaneously on NPTN affiliates in five cities: Buffalo, NY; Cleveland, OH; Denver, CO; Tallahassee, FL; and Youngstown, OH. Thus, a comment from someone in Cleveland might be intermixed with something from a user in Tallahassee, followed by someone in Youngstown, or Denver, or Buffalo. PLEASE NOTE: IF YOU POST A COMMENT TO ANY OF THESE BOARDS IT WILL NOT APPEAR IMMEDIATELY. Your posting will first be routed to the NPTN machine in Cleveland for distribution to all five systems -- including back to the system of origin. Thus, it might be several hours before it is cleared for the network. In summary ... You are looking at one of the first attempts BY CONGRESS to use this medium on a national scale to hold discussions on the policy issues that are before it. Use it well. If you have any questions about this project, please feel free to contact Tom Grundner at: tmg@nptn.org or William Beasley at: wab@nptn.org <<< ISSUE #1: SOCIAL SECURITY AND CUSTOMER INTERACTION >>> The general question in this area is: How can the Social Security Administration improve customer interactions by utilizing telecomputing technology? You are free, of course, to comment on anything you'd like, but some specific questions or issues might include: * Should routine requests for such things as replacement Social Security cards be made available via the telecom- puting networks in addition to the present methods. * Should informational materials such as explanations of benefits be made available via the telecomputing networks. * Should earnings record be available utilizing the tele- computing networks. * If any of the above were done, specifically how do you think your life would be improved (or not-improved) by it? * Are there issues of confidentiality, data security, and privacy that bother you? <<< ISSUE #2: NETWORK ACCESS TO BENEFIT FILING SERVICES >>> The general question in this area is: Could this new technology help the Social Security Administration improve the process of filing for benefits? You are free, of course, to comment on anything you'd like, but some specific questions or issues might include: * Should the Social Security Administration allow for the filing of benefits via the telecomputing networks? * Should the Social Security Administration utilize the electronic networks to file for appeals and transfer records and supporting documents in regard to the substantiation of claims. * If any of the above were done, specifically how do you think your life would be improved (or not-improved) by it? * Are there issues of confidentiality, data security, and privacy that bother you? <<< ISSUE #3: DISTRIBUTION OF BENEFITS >>> The general question in this area is: What do you think is the best way for the SSA to distribute monthly benefits? You are free, of course, to comment on anything you'd like, but some specific questions or issues might include: * Should the Social Security Administration continue to mail checks to individuals or should all disbursements be made via Electronic Fund Transfers or Electronic Benefit Transfers? * In order to spread the workload of the Social Security Administration there is talk of changing the disbursement of benefits from the first of the month to a staggered payment date, i.e. 1st, 10th, 20th of the month. How would this effect you? Would you find it acceptable? * Should the Social Security Administration expand the use of the EBT (Electronic Benefit Transfer) in co-operation with other agencies. * Should the Social Security Administration work toward combining use of the EBT (Electronic Benefit Transfer) with various State government benefit programs? * If any of the above were done, specifically how do you think your life would be improved (or not-improved) by it? * Are there issues of confidentiality, data security, and privacy that bother you? <<< ISSUE #4: GENERAL SATISFACTION WITH THE SSA >>> The general question in this area is: To what extent have you been satisfied with your interactions with the Social Security Administration? You are free, of course, to comment on anything you'd like, but some specific questions or issues might include: * In the past year did you have occasion to contact the Social Security Administration? If so, tell us about that experience. * How did you contact them - In person visit to Social Security Administration Office - Telephone Call to local Social Security Administration - Telephone Call to 800 number of Social Security Admin. - Postal Mail - Community meeting with Field Representative of the - Social Security Administration - Other * On a scale of 0 to 5 with 5 being the highest rating, how would you rate your experience. * How long did it take for you to receive a satisfactory answer from the Social Security Administration? * If you visited the local office in person how long did you have to wait before you were seen? * If you telephoned, did you have any problems getting to talk to someone. * If you mailed a letter, how long did you wait before you received an answer? * Was the information provided to you understandable? * Would you be willing to utilize a telecomputing network to contact the Social Security Administration? * From your experience, how would you suggest the Social Security Administration improve their service to you? [End of information from Youngstown Freenet] As of January 10, 1993 there were no messages yet in any of the four forums, so I assume this is brand new. Remember, if you want to send comments on any of these issues, you need to log onto one of the five Freenet systems listed above. If you cannot do that for some reason, I suggest contacting one of the two NPTN people mentioned (Tom Grundner at: tmg@nptn.org or William Beasley at: wab@nptn.org) and asking for advice.

Well, there are two parts to this. One is implementing CLID, the other is giving ANI to other operators so that they may use that information for CLID. The first CLID customers in Norway will be ISDN users. However, the question is not only about technology. There's been a long discussion about the privacy considerations (from the originating end of the call). I'm not the right person to give a neutral account of that debate. The question about sending ANI out of Norway is in general covered by CCITT agreements. It may be done, but I don't like to open up that privacy debate once more. Wrt the privacy debate, it's funny to note that there wasn't much said about the privacy of the people being called. One reason for this may be that CLID was only viewed as available to ISDN customers, and that would mean business customers. Personally I look very much forward to the moment I can screen them late night calls. The privacy debate extends to detailed billing as well as CLID, but opposition comes from the comsumer rights people. Personally I was a bit bored at this stage, but I managed to stay just to watch the fun when the concept of "B number masking" was introduced. > Apart from the idea of doing all exchange modernisation and number > changes at ten to four in the afternoon ... on Thursday afternoons, > isn't it?

It might be for you, too, depending on how you plan to use it. After talking to five different people in the local GTE residential and business sales offices (favorite quote: "What is ISDN?", from two people in residential sales), I finally found someone willing to admit that they could sell me ISDN service. Interestingly enough, their price was $48/month for 2B+D, which would provide two voice lines and two phone numbers. This is about the same price as two unmeasured POTS lines -- what a deal. Of course, this is GTE. There has to be a catch. For data, they charge the same as measured-by-minute local calls. I asked if that mightn't be perhaps the silliest way to bill it (data calls by the minute), when a major benefit of digital telephony is that when I'm not using it, I'm _not using it_! (mostly) That of course didn't phase them. Even at pennies/minute, the advantage of faster speed is removed by cost when I can do plain-ol' 14.4K with compression for "free." Is _anyone_ bothering to campaign phone companies and Public Utilities Commissions so that we can get this tarriffed in a reasonable manner (at least in places other than Oregon)? [Side note for those keeping score: US West in Portland offers 2B+D for $90/month, no limit on data. Of course, you can't make an ISDN data call between GTE and US West just yet, but they're working on it.] Rob Knauerhase [knauer@ibeam.intel.com] Intel Mobile Software Lab ------------------------------ Date: Fri, 14 Jan 94 02:29 PST From: rlm@helen.surfcty.com (Robert L.

Additional news: while the site survey hasn't been done yet, I'm assured by someone else locally that Pac*Bell will install any needed repeaters free, a big turnaround from the days when that company required big fees to extend digital services. But the best news is yet to come. According to my friend the ISDN reseller, the new rate card for Pac*Bell digital services shows some BIG price cuts. Unfortunately, I don't have the info with me, but suffice it to say that T1 will be nearly cheap enough to be within reach of the residential high-volume talker -- around $135 a month is what I remember him saying. (But there's still an impossibly high installation fee of around $700.) And get this: no per-mile charges out of the CO. Switched 56 and SDS (Pac*Bell's ISDN offering) will be substantially cheaper. It may not be very long before we start talking about residential T1-class services. (I hope that before this becomes reality, Pac*Bell drops the $0.01/min for local calls it charges under the provisional business tarriff; residential service is residential service!) I expect that one of the hot topics this year will be T1 and/or ISDN ISA and NuBus cards, this supplanting the continuous dull roar of speculation and hearsay surrounding the ITU's v.37 standard-in-progress.

If you use, for example blue/white and orange/white, the telephone signal isn't travelling properly through a pair, but instead is using one wire from each twisted pair. Hooking a second line up will virtually guarantee crosstalk. Also, I've seen installations which connect the ring lead of two phone wires together. This effectively unbalances the pair from the connection point all the way back to the central office, which makes for huge cross- talk problems. Routing of unshielded twisted-pair is important, too. Keep it at least two inches away from any metal object such as water pipes, gas pipes, iron sewage lines, air ducts, electrical conduit, or electrical power wiring. (Don't sweat nails or the occasional pipe hanger.) The original intent of the separation was to provide air space between telephone wire and grounded objects such that a lightning strike wouldn't arc over and damage the wire, but the practice has proven to benefit crosstalk, too. If you can't avoid running next to metal, consider using shielded twisted-pair wire instead. You need only an overall shield, not a shield around every pair. Care in wiring makes all the difference in the world.

Even used? David, The cheapest I'm aware of is the PTT 5101, if you can find one used. They are located in Huntsville, AL and you can call (205) 971-8001 for more information. Old TAS boxes are out there as well, like the original Model 100. You can check with TAS at (908) 544-8700. To round it all out, Consultronics (formerly AEA) has a box as well, but I haven't heard of used ones for sale as Consultronics has been upgrading existing boxes; try (613) 225-6087 and see what they say. Teltone has some boxes, but they don't have the right loss characteristics. If you prefer, you can get these phone simulators on rental if your need is short-term, and the rental prices are coming down on the older units. Another option is to find a company with the capability of performing the testing for you. There is Henderson Communications in San Moreno CA at 909-788-8849, or Satchell Evaluations (me) could do it (I'm at 702- 832-7157) for perhaps much less than you could get a simulator. If you are looking for go/no-go acceptance tests, it should cost you very little to use one of the independent test labs.

I just bought "PhoneDisc USA" at the local Egghead Software store. US$65.00 for two discs of residential listings (they claim 80 million listings from telephone directories across the country on the two discs). Pretty cool, except: * It's out of date as soon as it's published, * Only includes listed numbers (the company has phone numbers from sources other than telephone directories, but they seem to filter out unlisted numbers on these discs - I don't think they do that on their commercial discs), * You can only search on a person's name, and then limit the search based on their address, city, state, zip, or area code - i.e., can't "reverse lookup" a phone number to see who it belongs to. The target audience for this package is apparently people who have a PC in their home, and just want an on-line phone directory - it's not targetted for commercial usage (the company that sells this - sorry, I don't remember who it is - has other products for business use, with things like "reverse lookup" capability, which they will be happy to sell you ...).

I then dialed another friend; 3) After I said "Hello", I flashed the line so we were all connected and started to chat; 4) I picked up LINE 2 in my house, and dialed my number, BUSY! So, I placed another call to Bell of PA. I explained again my situation, receiving a CW tone during a three way call. The agent looked into some book she had, and explained to me that I live in an area with a "5E" switching system, in which CW and 3WC can have NO interaction. Whereas my friend who lives in a different area has a "1A" switching system, where they DO interact! Now, those two numbers I only put down from memory, so I may be wrong. The only thing I have noticed different between my system and his is that when he gets a CW and I am online, I hear a CLICK, and when I get a CW, the person on the phone with me gets one second of silence. Also interesting is that on his system, if he calls me three way, and in the middle of the call he gets a CW, when he switches to that CW line, I can actually keep talking to the other party! It is a pain that my line is busy during 3WC, because I ordered CW for the specific reason of NOT loosing calls!

Anyone know? and Pat replied that it depends on whether the 3WC is established or is in the third-party consultation phase when the incoming call arrives as to whether or not it will invoke CW. Most switches can be configured to either allow or disallow CW during a 3WC *after* all parties in the 3WC are connected. I once had CW & 3WC from a 1A, and I could get a CW beep during a 3WC.

The only thing I can think of that could make that statement true is that it is apparently possible to design the telephone hardware to block the DTMF frequencies coming through the handset. I had an AT&T phone and a Commodore VIC-20 modem some many years ago. The phone was one of the first with the "limited-travel" buttons on the keypad, around 1982. The modem plugged into the handset cord and sent DTMF tones down the wire to dial, using your base unit phone for everything else. On the old phone I had, it worked fine, but on the AT&T phone, it wouldn't even break dialtone. I called AT&T and they told me that they had deliberately designed the phone not to allow DTMF through the handset, although they steadfastly refused to say why. I don't have any tech specs on this point, and in fact no longer own that phone, so I can't tell you anything beyond that.

Over here some systems are capable of filtering out the MF tones so that even if the keypad enabled MF, it just wouldn't get through. In fact this is necessary on some PABXs where the MF digits dialed are processed by the switch before sending to line -- otherwise the CO would see the same digit twice, and generate a wrong connection. And if we can do it, the RBOCs certainly can. They may not be doing it now -- it is after all a political issue, not a telecomms issue, but if the community still sees the telco as the villain, even when tone dialers are used, it would be a very simple matter for the telcos to put MF filters in.

My results indicated that > flat-rate local calling is readily available everywhere. Depends on what you mean by "flat-rate". If you mean that local calls are untimed, then you are probably correct. If, however, you mean that there is no charge for individual local calls, that is not the case in many areas. Ameritech in particular has tried to do away with no-charge local calls; they've been successful in Wisconsin and (I think) parts of Illinois. I think when we talk about this issue, there are a couple things to keep in mind: 1) Telephone CUSTOMERS do not want to be charged on a per-call or per-minute basis. This was actually put to a vote of the people in at least two states (Maine and Oregon, back in 1986 I believe), and in those states the people voted to ban mandatory measured service by a considerable margin. This was the case even though under the phone company proposal pending at the time, there would have been a cap on the maximum amount that could be charged for local calls (something like $19 as I recall). In at least those two states, there will be true flat rate service for the forseeable future. 2) If you consider the components of local telephone service, charging on a per call or per-minute basis generally doesn't make sense (except as an artificial means of raising revenue). The two major components involved in the provision of local telephone service are outside plant (the wires, cables, and terminal blocks and similar equipment that carry service to your home) and the central office switch. The costs for outside plant are totally unrelated to usage except in very rare circumstances. The wires and cables do not "wear out" faster through use. Most of the costs of maintaining outside plant is associated with replacement of aging facilities, repairing damaged equipment and cables, and upgrading equipment to keep up with growing populations. None of these occur with any greater frequency because a line is used more. From the standpoint of outside plant, whether a line is in use zero hours a day, 24 hours a day, or somewhere in between makes no difference whatsoever. In regard to central office equipment, the only time increased usage becomes a factor is when it is so high that extra call handling capacity must be added to the switch. Normally, telephone switches are designed to handle the maximum number of calls placed during peak calling periods and then some. Most residential customers do not place the majority of their calls during peak calling periods (that is, during the business day). For all practical purposes, once the central office switch has been installed, there are no additional costs to the phone company whether subscribers use their phones a lot or a little. Of course, there is the argument that the phone company can get by with installing a switch with lower capacity in the first place, if it can discourage phone usage. In my opinion, this sort of backward thinking is a disservice to customers. I can't imagine that in the grand scheme of things it costs the telco that much more to provide plenty of capacity right from the start, and it's a one-time cost that can be amortized over the life of the switch (which is at least ten to fifteen years, even with today's fast-changing technology). If anything, today's technology should make it possible to charge less for calls, especially local calls. For example, most interoffice trunking is now on fiber optic cables which provide far greater call capacity at less cost the the former system of interoffice copper cables. > In article dave_oshea@wiltel.com (Dave > O'Shea) writes: >> though I wouldn't be terribly surprised to see some alternative >> local loop providers selling a "flat-rate"-type service to people who >> are priced out of the market by the LEC's. > I rather doubt it; residential flat rate local calling is justified as > a giveaway of excess capacity that must be there in order to serve the > business community during "prime time". Alternate providers would tend > to establish rate structures that discourage residential customers so > that they don't have to build local plant to serve the low-volume > customers. There are a couple of reasons why I tend to think that may not happen. First, telcos are still regulated by state PUC's, and in at least some states alternative carriers will be required to serve all comers. For another thing, in some areas the current LEC's will be required to unbundle their local service offerings, charging separately for the use of outside plant (which will almost certainly be on an unmeasured basis) and for provision of dial tone from their switch. Alternate service providers in those states will be allowed to lease circuits (between the C.O. and the customer's premises) from telco on a month-to-month basis, and connect those to their own switches. In such areas there will be no disincintive to serve residential customers, since they won't have to build any outside plant. And it may well be that such alternate providers will choose to offer true flat-rate calling, at least between customers of their switch. Even in areas where the option to rent circuits from the telco doesn't exist, they may be able to get to residential customers via cable TV lines, small-cell wireless technology, or some other method that is usage insensitive. Another thing to keep in mind is that the heaviest users of residential phone service (other than teenagers) are personal computer users with modems. However, new technologies may be developed that effectively takes most of that traffic off of the phone wires. For example, there's no reason that full Usenet news feeds couldn't be transmitted direct to the home via small satellite dishes (or via a channel on the local cable TV system) ... the user would simply need a computer (or other "box") with enough intelligence to selectively retain only those newsgroups and articles of interest. Under such a system, the user would only need to make a call in order to transmit or recieve e-mail, or to upload Usenet news articles. I believe there is something similar to this available already, but it is priced out of reach of the home user (it's economical in some cases for those who want a full Usenet feed, however). But this cost could well drop as demand for access to the Internet rises. And beyond that, data communications are much more suitable for wireless technologies, since data users can tolerate small delays during periods of extreme congestion much more readily than voice users. So if telcos are figuring that they can make big bucks off of modem users if only they can charge for local calls, they might want to think further about that, since new technology could obsolete that particular use of the phone lines rather quickly if the need arises. >> One of the big reasons that long distance rates seem to "bottom out" >> somewhere in the 10 cents/minute rate, even for the most humongous >> customers is that the LD carriers have to pay most of that to the LEC >> for the local loop.

A rational rate structure would charge all customers something remotely related to the actual costs associated with providing a particular service. Under a truly rational rate structure, your basic monthly bill would be much higher (as much as double what it is now, maybe even a bit more), but you'd have essentially free local calling within your home LATA (and maybe even adjacent LATA's), and very low cost calling to the rest of the country. Custom calling services would be provided free, or at very low cost (just enough to amortize any additional software costs required to provide those features). The problem with this is that most customers, especially residential customers (and especially senior citizens) would squawk like stuck pigs if their monthly phone rates doubled or tripled, even if you gave them free long distance calling to anywhere in the country. Actually, if local service were to be pretty much deregulated (and full competition allowed), I could conceivably see a day where you might pay, say, $35 - $40 per month and get free, unlimited local calling anywhere in your LATA. You'd then pay maybe about the same amount to a long distance company to get unlimited calling anywhere in the country (or at least within the continental U.S.). If you didn't have that much usage in a month, you'd have the option to be on a measured plan instead. I do not think this will happen until and unless there are some substantial changes in the current regulatory framework. Actually, about the only regulations that I would like to see (which we do NOT have now) would be ones that would prevent telcos from "bundling" service in such a way that you can only get circuits from them if you also get dial tone from them. >> If an employee is worth telecommuting, even a $4/hour connection >> charge is fairly minor in the face of, say, a $65,000 salary/benefits >> package.

Eight hours at $4/hour is $32 a day. This is > at least the equivalent of another hour's salary. Hardly negligible. I agree with this last point completely. I don't claim to be psychic, but I will predict that telecommuting will NEVER take off where there are per-minute charges involved. By that I mean it will never get to the point where anyone other than the top executives and maybe a very few other employees will be allowed to work outside the home. No company in their right mind would pay $32 a day for an employee to telecommute when that same employee could drive to work on under $5 worth of gas, and be physically present when needed. And keep in mind that it wouldn't be just the $4/hour in the example mentioned, there's also extra monthly charges for the extra phone lines required, plus equipment costs at both ends.

Unfortunately, I do not trust telco to do correct billing without having some way to check up on them. What do you folks do in Denmark when you get a bill that says you've used 100,000 units (meter pulses?) of service and you think it should be more like 1,000? Do you pay without protest? Do you refuse to pay and let telco disconnect your service for non-payment? Do you just assume that your telco so perfect that they never make mistakes? Or do you just figure that getting overbilled is part of the cost of having a phone? I'm sorry, but I don't like any of those options. Jack [TELECOM Digest Editor's Note: The thing Jack Decker and other pro- ponents of flat rate billing seem to forget or ignore is that in most instances of measured billing, the majority of telephone subscribers actually pay LESS for service than with flat rate. A small minority of the users -- mainly people with telephone intensive lifestyles such as modem users -- pay more. Where flat rate service exists, the rate is invariably evened out in such a way that telco still makes money based on average usage which tends to run high on the curve due to modem (and similar heavy volume) users. In other words, if you want to average it out and set a 'flat rate', telco still won't be the loser, but the majority of the users will be. He mentions two areas where people voted against measured service but exactly the opposite was the case in Chicago in the middle 1980's when IBT dropped its 'metro calling plans' in favor of pay-as-you-use it. Yes, the modem users screamed bloody murder, but all sorts of telephone users other- wise were happy to see their bill go down a couple dollars monthly. One of the major consumer organizations here endorsed the new plan without reservations. Flat rate calling plans work much the same way as insurance actuarial tables: let a few people in a given category cause some major expenses and everyone pays. I can't say that I benefitted from measured service here (in fact I wound up paying more than before by quite a bit) but it is a lot fairer to the 99 percent of the public who does not use modems or stay on a phone connection for hours at a time each day.

However, nationwide USA "800" numbers may be sent to different places in different parts of the country (e.g., my insurance company's nationwide 800 number is sent to the nearest office) ... and many USA "800" numbers _do_ have geographic restrictions (e.g., a specific area code, a specific state, a specific group of states), and are unassigned (or even reassigned) in other parts of the USA. Several questions: 1. How would 800 Directory Assistance (which, for the benefit of readers outside North America, is 800-555-1212), handle calls coming through USA Direct? I can imagine an AT&T operator asking such a person "what area code are you calling from?", as they often do here, and the conversation taking a turn for the worse. 2. If a USA Direct caller thought they could reach the same office of a company multiple times through their USA "800" number, would they have any guarantee that each call would come through the same gateway city each time (so it would be routed to the same office each time)? At least, the post implies that there were different gateways when calling from different countries. John R.

The report detailed the development of Unix and the philosophy behind it. There was a wonderful point made about the fact that each part of Unix is a small block in the overall scheme of things and that nobody can predict how these blocks will need to be arranged to do a certain job so they must be designed according to certain standards of input, output, and control in order to make them most useful. Unfortunately, this idea is still pretty foreign to many people who really should know better. We have a situation in which the computer operating systems gaining the most popularity use a graphical user interface instead of the command line or text-based interface which was the standard user interface until recently. The GUI or graphical user interface has been tauted as the end-all and be-all to make computing accessible to the general public. The problem is that the GUI makes access by blind people very difficult. Actually, it wrecks any kind of nonstandard I/O because we no longer have a situation in which input and output are separated from the program. The beauty of Unix and, to a lesser degree, such systems as CPM and DOS is that the original developers were smart enough to know that they could never cover all possible applications so they produced a set of great tools which allowed others to do like Isac Newton and stand on the shoulders of giants. GUI's are neither good nor bad in and of themselves, but they are a serious barrier to blind computer users and anybody else who needs to do things differently. Rather than choosing which interface works best for us, the software companies have in their most finite wisdom created a hideously complex operating system whose manuals are thicker than many metropolitan telephone books and whose only hard and fast rule is that the rules are constantly changing. There are several companies working on interfaces to both the Microsoft and Apple graphical operating systems, but users who have shelled out hundreds of Dollars to buy these programs report that access is still difficult and problematic. The problem is that there isn't a large market for this sort of special software and the amount of time and skill needed to develop it means that somebody will need to be paid well for their time. I have no complaint about that as much as I feel that the software companies have created a bad problem in that it is not easy nor trivial to get nonstandard forms of I/O. The ideal solution would be for the operating system companies to design their interfaces with vectors or hooks which could be easily used as the input to special software which could treat the operating system as a black box and concentrate on providing whatever output or control is necessary for the user to manage the system. Finally, while I don't know what will happen in the future, I can almost promise what won't happen. The companies who produce the spread- sheets, word processors, etc that we use will not, nor should they be expected to, produce programs for blind users or other people who need nonstandard access. If something isn't done to solve this problem in a meaningful way, the information age will be only a dream for some. Martin McCormick WB5AGZ Stillwater, OK O.S.U.

But his contribution about the ways we can now organise society better with computers is certainly true -- it's just that this is evolutionary, not revolutionary. What I was trying to say is that technological change is less disruptive, and *less* revolutionary these days, than it has been for most of the last hundred years -- while conventional wisdom (especially in the computer and communications industries) tries to make us believe that it is *more*. Technologists are not at the centre of the universe -- we are just one of the parts. Gordan Palameta writes: > The point is, when we consider the impact of airplanes, automobiles, > etc. from our perspective, we are really compressing eighty years of > history. A fair comparison with computers would require a similar > eighty-year perspective. But we can take an 80 year perspective. Before Henry Ford came along, motor cars and aircraft were toys for the technophiles and for the expert mechanics. There were eighty years of technological development, but only 20 years of social impact. It has been the same over the last eighty years with computers -- right from the days of Babbage and Pascal, if you want to stretch the word 'computer' that far. My estimate of 20 years really only covers the period when computers began to make an impact on the community, not when they were custom-made devices used for vote-counting, or calculating ballistics, or performing military decryption. The technophile sees the development of planes extending back to Kittyhawk, while the community sees aircraft-development only going back to the days of the Ford Triplane and ending with the Jumbo Jet nearly 30 years ago. What has happened to commercial aircraft since then is largely trivia from the customer's viewpoint. The jumbo jet flying today might be a much more sophisticated machine than the first 727 Jumbo twenty-five years ago, but from the customer's viewpoint, it is inferior if it doesn't have more leg room. The pilot may notice an improvement, but the passengers don't. This is just the point. In the area of computers and communications the technological complexity and ingeniuty being exhibited by the technologists, is not now being reflected in social impact -- or at least, it's being reflected in changes with are relatively minor when compared to those of the first decade or so of commercial PC production. PCs will soon be telephone peripherals, about as exciting as a modern-day telephone handset. The linkage between social change and improvements in technology has decline because we are moving from core effects, to the periphery. This is always the way with technologies -- which is why we must be careful with infinite extrapolations. The curve always flattens -- not because technological innovation lessens, but because it becomes less relevant. I was involved in making a television series on aircraft and airports around the world in 1966, and we visited the Concorde factory in France, then went on to Boeing in Seattle. The Boeing minders, at that time, were keen that we should concentrate on the swing-wing SST (SuperSonic Transport) -- which was the data superhighway of air- transport at the time. But they hardly mentioned the first Jumbo 747 that was rolling off the assembly line, because it was too mundane. So I totally agree with Gordan when he says: > When considering the impact of technology, we tend to focus too much > on things that are flashy and highly visible. A generation ago, > people figured that by now we'd be zipping around in rocket ships and > flying to work with our own personal jet packs. Few bothered to > predict simple things like fax machines. A good electronic mail system with national and international backbones (like the Internet, but extended to the wider community so everyone has access, as they do to the Postal Service) would be much more socially useful and productive than videophones and videoconfer- encing and fibre-to-the-home ... but where do we put our money? And e-mail technologies needed have been around for years -- it is just that e-mail is so cheap to implement, that it is impossible for the telecos to make a profit. So e-mail backbone services need to be public infrastructure, not commercial services run by telephone companies. The commercial operators have a conflict-of-profits: each one-cent e-mail message is one less 20-cent less phone or fax call. If we leave it to free-market enterprise and we'll never get a good service. I agree with most of Michael Jacobs remarks, except for: > Too often we forget that the history of our civilization is a > history of technological progress. Sure, technology is a major contributor -- but he is attempting to place technology at the centre of the universe again -- and equating "technology" with "progress". We are just one of the parts -- and a lot of our technologies are useless, counter-productive, ridiculously costly, or outright destructive. ------------------------------ From: mds@access.digex.net (Michael D.

PAT] Pat, it sounds to me like you are willing to accept lower rates in the short term while giving up a considerable measure of control over your phone bill in the long run. I'm not arguing that people who take measured service don't often save money at first; in fact, I think it's been designed that way. The phone companies aren't above giving up a little revenue in the short term if they see the potential of making greater profits in the long run. My point, which you seem to have overlooked, is that the costs to the phone company are rarely increased by increased usage of telephone service, especially by residential customers. Therefore, it is arguably fairer to charge for phone service in a usage insensitive manner. The people of Maine and Oregon obviously thought it was fairer to do it that way. (By the way, I don't have much use for most "major consumer organizations"; I find they often have their own axes to grind. But, that's another topic for another time). You say that measured service "is a lot fairer to the 99 percent of the public who does not use modems or stay on a phone connection for hours at a time each day." I would agree with you IF the phone company's costs were being driven up by those customers, but I've yet to see any evidence that they are. Keep in mind that we're talking about residential customers here, and residential customers very seldom make heavy use of the telephone system during peak calling periods. Sure, a residential user may talk for hours at a time, but if it's in the evening when the central office which is loafing along at a fraction of its total call handling capacity, what does it matter? Keep in mind that since the phone company is a monopoly, they can juggle the rates any way they want. Suppose that when IBT introduced measured service in Chicago, they had chosen to price it in such a way that the average customer would have paid more than they did under the previous plan? They could have done that, you know, but obviously they wouldn't have had many takers for measured service if they'd done that. But if they had, perhaps now you might now be arguing that flat rate service is the better deal? I think that what many of the Baby Bells (and GTE) would like to do is get mandatory measured service in everywhere. Why? Because it makes rate increases easier to justify. Under flat rate service, when customers complain that their bills are too high, the PUC just might order the telco to lower their rates, or at least not approve any new rate increases. But when customers have measured service, then it's easier for telco to place the blame for high bills on customers: "If they want lower bills, they should make fewer calls!" Of course, if the day ever comes that virtually everyone has measured service, then telco can raise the rates so that the "average customer" is paying MORE than he would have under unmeasured service. You have to understand that there's a bit of psychology involved here. It's often easier to get a PUC to approve a rate increase of a penny or two per call than to approve an extra dollar or two per month on the total phone bill. It's like the AT&T commercials where they say "you're only saving pennies" without pointing out that as the units add up, so do those pennies. Right now, none of the Baby Bells have managed to get measured service throughout their service area, so they haven't been able to jack up measured service rates as much as they'd like to, because they know that regulators and consumers in other states would find out about the increases and use them as ammunition to forestall the implementation of mandatory measured service in the states where unmeasured service is still available. I think that instead of looking at Chicago as an example, it might be more instructive to look at places where virtually no flat rate service exists. Take Europe for example; even in countries where the phone system is fairly well developed, local phone charges are considerably higher than ours. I doubt you will find any place in the world (outside of the United States and Canada) where people can make as many calls and talk as long as the average person does here, and still receive a phone bill that's anywhere near as low as our bills are. A lot of those people would truly love the luxury of being able to pick up the phone and make a local call anytime they feel like it, without worrying about the costs. And what they have there is pretty close to what we would have here, if the telcos could get mandatory measured service put in place nationwide. One other thing, you always take swipes at modem users on this issue, but I think that's even a bit unfair for three reasons. First, many modem users are on business lines, and since most business lines are now measured, they're paying for their service anyway. Second, most residential modem users tend to make their calls in off-peak periods, so they're really not taxing the capacity of the phone system that much. But the third thing is that when most telcos here implement measured service, they charge on a per-call rather than per-minute basis. If we were to assume that the point of measured service was to discourage modem use, then it would make more sense to charge by the minute on local calls (because modem users tend to make longer calls), but that's done in VERY few areas of the country. It would make even more sense to charge extra only for calls made during the heaviest calling periods, but as far as I know, that's not done ANYWHERE in the United States for local calls. So I don't the the phone companies really have modem users (and people who stay on a phone connection for hours at a time) foremost in mind when they implement mandatory measured service, even if you think they're a major target. The bottom line is that while measured service may seem like a deal now, I would not assume that such will always be the case. This is the phone company's version of a "loss leader", something to convince you (whether "you" is the individual residential customer or the PUC of a state) that measured service is a good deal ... and never mind that there may be price increases around the corner. Think, Pat ... their costs are NOT usage based, and they can juggle the price of either measured or unmeasured service to make either one seem like the better deal at any point in time. Therefore, saying that measured service is "better" because the majority of customers are saving money with it is in reality making a value judgement based on the conscious actions of the phone company to make measured service a better deal AT THIS POINT IN TIME. When it's the ONLY deal available, you may suddenly find it's not such a bargain.

Henceforth, your monthly residential rate will be $2 + $1 for each letter of the alphabet removed from "A". Thus Abolafia will pay $2, Bernstein $3, Coletti $4, up to Zzzyandottie who will pay $27. This is perfectly fair, of course, because most people have names that are before "M", and thus come out in the cheaper half. Is this absurd? It is only a bit less arbitrary than most measured local service plans! Telephone rates are set by regulators because in a free market, price tends towards cost, but telephones are a monopoly so there is no free market. And in this monopoly world, the historical regulatory regime has NOT been cost, but "value of service". And that's basically whatever your regulator says it is. One approach, of course, is to price telephone service (80%+ of which is a fixed cost, whether you never use it or never hang up) based upon usage. Illinois Bell and New York Telephone both do this a lot. In the case of NY City, the state regulators made them do a fancy cost of service study, and they ended up with a complex three-rate-period multi-band structure that bottoms out under a penny a minute for short-haul nighttime calls. (Residence can get untimed service.) Note though that NY City has an unusually complex and costly infra- structure, with so many COs, tandems, etc., to deal with. The trouble with overcharging for usage is that it reduces the economic efficiency of the network as a whole. Overprice (vis a vis true cost) usage rates discourage usage, so the usage-insensitive infrastructure (most of it) gets less usage than it should. The resource is wasted. The FCC makes telcos produce true cost data when making up the rates charged to long distnace carriers for delivering calls. These rates are then buggered by a formula that produces a subsidy (read: they're marked up), and they're entirely usage-based. But the mileage component is only about 1/100 of a cent per mile per minute. A call anywhere in a LATA usually costs about the same. Overcharging heavy local users or overcharging people named "Townson" is equally wrong. fred ------------------------------ From: dk@crl.com (David A.

In Oregon US West does provide flat rate service for both residential AND business customers. The Portland local calling area extends fifty miles! It's amazing. It is also probably one of the reasons why business bypass service is not popular in that area, whereas in San Francisco it is a booming business (measured business rate and a local calling area of about ten miles). ------------------------------ Date: Sat, 15 Jan 94 16:39:34 CST From: varney@ihlpe.att.com Subject: Re: Unmetered Local Service Organization: AT&T In article ao944@yfn.ysu.edu (Jack Decker) writes: > On Wed Jan 12 08:35:33 1994, lars@Eskimo.CPH.CMC.COM (Lars Poulsen) > wrote: >> A.

It all adds up. I disagree, but only because $4/hour is unlikely -- at $2/hour or $16 per day, it costs about the same as floor space, parking, taxes, services, etc. When urban companies start paying real money when the number of single-car commuters doesn't drop, telecommuting will be a real option. In addition, it's not the $65K folks that are candidates. It's the skilled clerks and sales folks. If you can pay these people $2/hour less in salary/benefits in exchange for work-at-home (or work-in-the- car), telecommuting looks pretty good. Better yet, you can compete for workers that would be unwilling to commute to your work site -- those with small kids, a sick parent or poor access to transportation will usually work for less in exchange for a presence at home (perhaps part-time).

I know of nobody (yourself included) whose bill has decreased with measured service. Yes I know that the telcos propaganda said this would be true but it is not true for anyone who uses the phone. It is not even true for those who dont. Basic service is way up, supplemental charges are up too. > Where flat rate service exists, the rate is invariably evened out in > such a way that telco still makes money based on average usage which > tends to run high on the curve due to modem (and similar heavy volume) > users. Hogwash. When we had callpacks here, you still had the option of measured zero service where each call cost roughly what it does now. Noobody was forced to take any callpacks. They took them because they made sense to consumers. We had several 'paks' to choose from too, including certain numbers of units, on up to unlimited and super unlimited, which reached almost everywhere in the LATA. All that this measured service has done is make timed toll calls out of calls which were untimed local calls and have driven the average phone bill up, not down. > He mentions two areas here people voted against measured service but > exactly the opposite was the case in Chicago in the middle 1980's when > IBT dropped its 'metro calling plans' in favor of pay-as-you-use it. Er, I don't remember any vote in Chicago where the 'opposite' happened. I remember the company notifying us that our callpaks were to be termin- ated and how wonderful it will be. > Yes, the modem users screamed bloody murder, but all sorts of > telephone users otherwise were happy to see their bill go down a > couple dollars monthly. ... while most other people who actually USE their phones saw their bills skyrocket. Sure Gramma and Grampa with their rotary black phone who call junior once a month on the next block, saves a couple of bucks but most people, I feel, saw dramatic increases. In Chicago you have an eight mile radius from your CO to the called CO for a one time charge of about five cents. If your CO is on the lake, however, your eight miles east is nil. What was once an untimed call from the North side of Chicago to the South side (even under measured zero in the call-pak days) is now timed by the minute. > One of the major consumer organizations here endorsed the new plan > without reservations.

PAT] 99%? You are telling us that 99% of the phone users in 1990's have benefitted from measured service? I'd love to see those statistics. Pat, I know you love to defend the corporations while they are, at the same time, sucking you dry, but c'mon ol buddy, lets get real. This is the 1990's. Everyone uses the phone. The days of granny in her apartment who made five calls a month are, for the most part, history. And your modem calls have not driven you bankrupt. You and I make virtually all our modem calls to local, untimed numbers. Telcom instituted measured service to make more money, not to save money for users. Period! To suggest that the majority of telephone subscribers are better off with measured service than they were with call-paks and calling plans, is absurd. What has happened is that our choice over the most economical plans have been removed. In their place is public relations jive. Pat, I love your Digest, and we are personal friends, but when I hear you preach of how benevolent telecommunications corporations are and how much better we all are off because of their actions, I have to jump in and say 'wake up'.

When Call-Pak Unlimited disappeared from the Chicago area, my calling patterns changed dramatically. The very first month of measured service, I went from 3500 units to 800, and my bill _doubled_ from around $40 to over $80. My average bill today is about $120, custom features excluded; the way I figure it, over ten times what I used to pay per unit. In any event, the smallest bill we've had since was much larger than the largest bill we had during the Call-Pak days. I have yet to meet _anyone_, even the little old lady downstairs with a retirement income who seldom calls anyone, whose bill went down when Call-Pak disappeared. (Perhaps you'll be the first?) A few people told me their bills went up only 50% or so; one only went up 25-30%. My modem line is NOT included in the current $120 figure; perhaps I should add in the $60 I spend on that to even it out, since I used one line for everything in the Call-pak days. (Make it $40 to remove the charges for the second line. That keeps everything down to about 13 times the original cost.) > I can't say that I benefitted from measured service here (in fact I > wound up paying more than before by quite a bit) but it is a lot > fairer to the 99 percent of the public who does not use modems or stay > on a phone connection for hours at a time each day. PAT] Guess you won't be the first (see above) after all ... I still can't see why it costs me more for a one-hour, 2 AM modem call across town than it costs Mabel down the street for a prime-time half-hour yap with Gert across town. It certainly costs the phone company a LOT less, in raw dollars as well as in actual resource allocation. (Non-Chicago-area folks: the 9 PM to 8 AM discount is 40%.) Cliff Sharp clifto@indep1.chi.il.us WA9PDM ------------------------------ From: TELECOM Digest Editor Subject: Re: Unmetered Local Service Date: Sun, 16 Jan 1994 09:00:00 CST Some responses are in order on this cold day in Hell ... for the past 39 hours (Friday about 6 PM through Sunday at 9 AM) the temperature in Chicago and suburbs has been sub-zero with a drop to fourteen below zero Friday overnight into Saturday morning; a 'high' temperature of two below zero Saturday and eleven below last night. We're told things may 'warm up' to the single digits today. None the less, it warms my heart to read messages from you guys singling out telco as the one utility service which you feel should be an exception to the 'pay for what you use' rule. Would you like to pay for your electrical service based on some average amount that all your neighbors, including the big factory across town uses? The factory would love having the electric bill averaged out to some community-wide fee per month. Would you object to paying a flat rate for your gas or your water based on some amount which includes the public laundry down the street with all the washers and dryers running all the time? Betcha the owner of the laundry would consider it to be 'fair'. Jack Decker agrees with me that frequently (but only 'at first' in his opinion) the costs to many subscribers are lower, and on this point he apparently would be in disagreement with Bill Pfieffer and Cliff Sharp who feel the bills always are more. Jack says the catch is that telco is willing to promote what is sometimes called a 'loss-leader' in order to later present a more palatable dinner to the regulators. It is easier to get them to go along with a half-pence or so here and there than a dollar or two per month. Jack contends that the use of the phone does not affect telco's costs, and while that is partly true (and more true than it is in the case of the gas, electric or water utilities, all of whom have to obtain and pay for (or 'manufacture' in the case of electricity) the product they are passing along), it is not entirely true since the size and extent of the *common equipment* telco must install and maintain DOES depend on the extent to which it is used. The general public does not know this, but I would expect most telecom readers to realize that telco does not have wires from every phone to every other phone and that said wires sit there idle in between calls. The common equipment is continually being swapped around among users of the moment. Typically, a telco has the physical capacity to serve only about ten to fifteen percent of its customers at any one time. If its customers tie up the common equipment for long periods of time then more common equipment is needed. Consider the car rental business: Hertz had a couple million customers last year. They do not own a couple million cars, but rather, they own a few thousand vehicles which are constantly being shuffled around among customers and locations (where the company operates) to meet the demand at the company's busiest times. Ditto with telco. While Fred G. seems to think it is equally absurd to charge by the letters in one's last name as it is to charge by the amount of usage, he ignores the fact that one's name has no relevance to one's use of the phone while one's use of the phone has a direct relevance to the amount of equipment telco must maintain to make it all work right. I agree with Fred that my name has no bearing on anything, but the fact that I have tied up a circuit between Skokie and Evanston for awhile typing out this answer does have a bearing on the cost. Jack suggests looking at Europe where 'costs are considerably higher'. Yes, they are higher in Europe (where they also have virtual monopoly phone service in a few countries), and yes phone charges are higher in any event. But this is not due to measured service, it is due to the lack of technological development in telecom. You don't wait three years to get phone service in the USA as you do in some places in Europe either. In general, phones cost more and provide less value in Europe than in the USA regardless of how the bill is calculated. Bill Pfieffer does not recall 'any votes in Chicago' and that is because there were no votes taken. But the Consumer's Utility Board (known locally as CUB) which functions as a citizen's 'watchdog' of the state regulators (the Illinois Commerce Commission) said they liked the idea of measured service for the simple reason that the old plan (a combination of measured and unmeasured 'local community service' plus area-wide metro 'call-pak' and 'unlimited call-pak' service was grossly unfair to the suburbanites while being overly generous to residents of Chicago. I would agree in general with Jack Decker's side note about 'consumer groups with their own axes to grind' and was very surprised to find myself in basic agreement with CUB's premises at the time. As Bill points out, we now have an 'eight mile local zone' in which residence calls cost but a single 'unit' and are untimed. A 'unit' is roughly three to four cents and we get discounts on this based on the time of day and the number of units used per month. The local zone is all the exchanges in the central office serving you plus all the exchanges in the contiguous central offices. All of northern Illinois (not just Chicago) is now under this plan. What Bill says is true: the subscribers who live along the lakefront do not get eight miles to the east since there are no central offices out in Lake Michigan, but they do get eight miles north, south and west. Under the old plans, there were a number of flaws which made them unfair to various users. For example, every user had untimed local calling with calls *in the corporate limits of his community* rated at one message 'unit'. Talk one minute or talk all day, no matter. For people in Golf, Illinois (a tiny village right next to Skokie) that meant one exchange, and a distance of five blocks from one side of the village to the other. For people in Chicago, that meant a distance of *thirty miles* from one side of town to the other at the most extreme angles of direction; easily 25 miles for everyone else and dozens (in those days) of exchanges. Under the old local plan, we got 80 'units' per month to use as we saw fit as part of the monthly fee. You could make 80 (or 120, 180 or 240) local calls or some lesser number of calls to other communities with the number of 'units' charged being based on time connected plus distance. That part was fair enough, but if one decided to get 'unlimited call pak' (the next step above 240 units) because one was on the phone a lot, then guess what? If you were calling anywhere outside the so-called 'inner met area' your units didn't matter ... those calls were coin-rated, and your units were wasted. Grandma might not use a single one of her 80 units allotted as part of her monthly bill, but every Sunday afternoon when she called Bill's friend Junior out in Aurora she'd get nipped for forty cents in coins. Under the old, highly-touted (by some people, and admittedly while I lived in Chicago-proper I was one such person) 'unlimited call pak plans' all the plans were heavily biased in favor of Chicago residents to the detriment of the suburbanites. All the plans used as their territory a starting point of State and Madison Streets in downtown Chicago then expanded outward in rings or circles. The 'inner met area' was 28 miles *from downtown Chicago* in any direc- tion. That was fine if you were in downtown Chicago or even anywhere in Chicago. The poor guy who lived in Wheaton, Illinois could call *anywhere* to the east/northeast/southeast on that plan but if he wanted to call west/northwest/southwest he had about three or four city blocks he could call under the unlimited plan then *his* calls became coin-rated for westerly points. The next size unlimited call-pak went forty miles *from downtown Chicago* and picked up such places as Aurora, Illinois on the outer edge of (what was then 312 and now is 708) plus bits here and there of 815. Well, that was fine until you moved to Fox Lake, Aurora, Zion, or Joliet to name a few examples. Then you were on the outer edge of the 'outer-met unlimited call-pak area' and you could call north and east all you wanted but not south or west (if Zion or way up north then the reverse was true; you got calls south and to a limited extent west, but being on the lake you got nothing east and you bumped into the Wisconsin state line a mile or two north of you and a whole new LATA). So people living in the outer suburbs had quite a choice for phone service: local area which gave them their puny little town with all of one or two exchanges or they could get 'outer-met unlimited service' based on rates and mileage from downtown Chicago from which they were already removed by forty miles or so. There was no inbetween type plan for those people. A very sensible plan was developed where the entire northern Illinois area would be treated as one large metro area for local calling. All 'local' zones would be relative to where you were actually at and all 'local' zones would be the same size regardless of what town you actually lived in. Everyone across northern Illinois gets eight miles in any direction from them. Telco does not choose who lives by the lake and who lives elsewhere. Anyway, as a side note, along the lake is **so bad** now in terms of nasty people, nasty violent crimes, drug sales, run-down and horrible housing, etc I can't imagine why anyone would live there; I'll sure never return to Chicago/Rogers Park having had a taste of Skokie! But, we get eight miles in any geographically possible direction, we pay three or four cents per *call* for these (or less depending on time of day and volume of calls per month dis- counts) and we pay progressively more for each cluster of phones in eight mile groups beyond that. What could be fairer to *everyone* in a large metro area than that? That is, assuming you agree with my premise that the number and duration of calls does cost telco *something* even if the analogy to gas and electric service is not entirely right. Part of the problem is the government did not lay out all the villages and towns on a checkerboard pattern with the same population in each town and the same boundary lines, etc. We have some real weird layouts here and any 'local flatrate in your own community' type plan would never be fair. I agree they might have as an alternative developed some additional 'unlimited call-pak' plans with concentric rings whose centers were in places other than (in addition to) smack-dab in downtown Chicago favoring downtowners at the (increasing) expense of all other residents as far away from downtown as you went, but they did not. Instead they developed a checkerboard pattern with each person getting his own square and the squares on any side of him. The rates *were* reduced (under the old plans, 'units' cost 5.5 cents each where now they cost between 3-4 cents depending on how many and time of day) and the suburbanites gained some equality with the city people. Of course modem users *in the city* who had previously been able to call *anywhere else in the city* for that 5.5 cents per call (with a bundle of 80/120/180/240) as part of the prepaid package now lost large chunks of the city in exchange for picking up in many cases quite a few suburbs in the process at 3.5 cents per call, but the suburbanites in many cases doubled or tripled the territory they could call for their 5.5 cents at a new rate of 3.5 cents. Instead of a choice between very local and limited 'flatrate' service at a cheap cost or an area-wide plan which cost a fortune and only included calls aimed in the direction of downtown Chicago, suburbanites now get to call anywhere in their 'square' or the 'squares' around them at a decent rate. For telco, the switch from flatrate to measured was more or less revenue neutral here. The fact that phone bills are higher now is because we are using the phone more now than we were even ten years ago. The modem users disliked it because frankly, quite a few were accustomed to calling BBS's (in those days Internet connectivity was virtually zilch, we all dealt only with small systems around the area) all over the metro area -- a distance of several hundred square miles -- and staying on line for an hour at a time. And you can't tell me that the 'average' phone user spends an hour at a time, several times per day, or even several times per week) calling to a point 30-40 miles away. The fact is we can say in voice to one another in a minute or two that which takes 15-20 minutes or longer to type in via email or a message and most people do NOT construct stuff off line then call in to deliver it. They call the system they are using and construct their message then and there. That's why modem connections are going to be inherently longer than voice connections, and that is why the modem users screamed about measured service, for the same reason the factory would love to have its electric and water usage on flat rate instead of meter. So often, 'what is best' is an applications-driven thing. Our old plans here *sucked* -- they were great for inner city Chicagoans and lousy for everyone else with the exception of heavy volume residential users in certain particular locations such as (go ahead and admit it Bill and Jack) inner-city modem users. Some phone customers here such as modem users calling all over the metro area and hanging on for hours at a time got a free ride for years. Now instead, Grandma gets to call Aurora or Zion without seeing a forty cent per minute coin-rated charge on her bill. So there is no mistake in where I am coming from, measured service costs me MORE -- much more, and I do not like it *for myself*, but overall, if you care about the rest of the greater metropolitan community, it is fairer this way.

Michael P. Deignan) Subject: Circa 1977 Rotary-Dial Trimline Date: 16 Jan 1994 14:39:49 GMT Organization: Small Business Systems, Inc., Esmond, RI 02917 I have just retired a circa-1977 rotary-dial "Bell System Property" Trimline phone from years of trusty service in our kitchen. (The pulse dial occasionally caused my modem to decide to pick up and answer the call in the midst of dialing a number -- quite annoying). Anyway, since I know there are folks here who collect these things, I thought I'd offer it up for sale. It works fine. The handset itself has a few minor cracks from years of dropping the handset on the kitchen floor. It could use a good dose of Fantastic or 409. Best offer takes it! Michael P.

Date: 16 Jan 94 10:58:15 EST Organization: Drew Univ Academic Computing In Volume 14, Issue 31, several contributors discuss the merits of NYTel's installing rotary phones to thwart drug dealers. Some writers were cynical of the move, pointing out that pocket tone dialers are widely available, but others suggested DMTF filters to prevent their use. NYTel _already_ has the capability to detect both keypad-generated and pocket-dialer generated tones and disconnect a call after some number of these tones. This "service" was in effect on many East Village telephones a year or two ago, and caused me to give up trying to use my voice mail from those phones. My experience is that NYTel is not forthcoming about how their phones are configured, so I'll offer a guess as to the real reason for rotary phones: If a phone has a keypad, the average customer expects to be able to use voicemail. At such a phone where tones don't work, (we've had this experience with COCOTs), s/he is likely to make several attempts, then call operators for credits or repair service to report problems. (I speak from experience. As a result of all this, I also had my calling card number stolen, having been asked to speak the number each time I asked for credit from a failed call.) Money is lost and ill will is generated. The AOSs don't care about this (and often don't provide access to operators or service personnel). But NYTel does care about this. The rotary phone says "Don't try to use voice mail from this phone." I suspect tone dialers won't work from these rotary phones, so some honest customers will still be frustrated, but fewer than before.

According to a headline article in the January 10, 1994 issue of {Network World}, in an attempt to reduce the exposure of military computers to viruses, the Defense Information Systems Agency (DISA) wants to take many military computers off the Net. According to the article, the DISA wants to rename all .mil domain addresses and hide them behind a single firewall. This has met with quiet but widespread disapproval from miltary users who cherish their Internet freedom. Military network managers say the plan may be technically unfeasible, and that a better way to improve system security would be to force all Internet-connected .mil sites to have MX firewalls. According to the article, "Leaked Defense Department e-mail suggests DISA made its decision about disconnecting the DDN without informing the Pentagon, which is now in the awkward position of explaining DISA's actions." The future of the DISA plan is unclear at the moment. Robert L.

Calling Directory Assistance at 1-617-555-1212 from my residence in AC 415 got me the number 936-1234 for telco (NYNEX) weather service in Boston. But then dialing 1-617-936-1234 repeatedly only gave me loud, intermittent, very scratchy static -- no ringing, no answer. When I called the long distance operator at 00 about this, her attempts got essentially the same result. She then went through an "inward long distance" operator in Boston, which did get me connected to the weather message. Anyone else encounter this same problem? Also, the local PacTel weather message is 936-1212; wouldn't it be handier if every LOC had the same number, so you could get the weather in any area code in the same way as you get Directory Assistance? (Maybe some AC's are so big one recording couldn't handle it?) P.S., Pat: Boston weather for next two days said daytime highs 8 to 12 F, nighttime lows -3 F, windchill factors -20 to -30 F; why am I even going there! [TELECOM Digest Editor's Note: Some of the weather forecasts are now on 976 numbers such as the one for Chicago. I don't think you can get those at all since most telcos no longer connect with the 976 numbers of other telcos. I get my local area time and temperature along with a recorded advertisement from Centel by dialing 708-296-7666. And PS to you too: our temperature here has been sub-zero (like ten or more degrees below zero) for nearly two days. Why am I staying here?

Date: Fri, 14 Jan 94 08:06:48 PST Organization: WilTel Greetings all ... Does anyone out there know of any LAN hub manufacturers who are working on hubs which will eventually include PBX chip sets and/or PBX-like features? (The underlying LAN technology doesn't really matter to me at this point, whether it's ATM, Fast Ethernet, or something else.) With the much-talked-about and much-anticipated coming of CTI, it seems logical (at least to me) that LAN hubs should become even more intelligent by adding PBX-like features. Or, will all this great CTI we keep hearing about simply be a bridge between the data world (the LAN) and the voice world (the PBX), as with the Novell-AT&T concept? Any help and/or opinions on the subject will be greatly appreciated. Thanks in advance. Kevin D. Tanner WilTel, Inc.

Their thing is that they (apparently dynamically) select amount ATT, Sprint, and MCI at the time of your call for the one with the lowest rates. We currently have MCI with "Friends and Family" and are pretty satisfied; there's a small group of people we call fairly often, in at least three different states. Is anyone using Touch 1, and would it really bring us savings over MCI? Please reply by email and I'll summarize -- I don't hang out in this newsgroup at the moment. Thanks!

The new NPA is 360, and will cover all of the area that is currently within 206, but outside of the Seattle/Tacoma area. I have not yet seen a map that shows exactly where the boundary will lie, but scuttlebutt is that the northern boundary of 206 should be somewhere between the King/Snohomish county line and the city of Everett, and the southern boundary just south of Tacoma. The eastern boundary should enclose the suburbs of Seattle that are currently dialed toll-free from the city, but will not go all the way to the boundary with 509 at the crest of the Cascade mountains. The western boundary should be in Puget Sound, with islands that are currently within the Seattle toll-free dialing area (Vashon, Bainbridge) to remain in 206. The split happens on 1/15/95, with permissive dialing until 7/9/95. So far I have seen nothing about this in the local media, so maybe you heard it here first.

This customer's answering machine will not operate (answer the call) from this office. I have taken the machine to another office and it works fine. This RSS has sealing current which uses 130 VDC on the ring and 70 VDC on the tip. When we remove the sealing current from the office we have 70 VDC over 20 VDC. I know that other customers have answering machines in this office area and are having no problems. Does anyone have any ideas on why this one won't work and what we could do to make it work? ------------------------------ Date: 16 Jan 1994 11:12:16 EDT From: Hinders, Thomas Subject: Learning Experience I moved from Wash DC (Silver Spring MD) to Phila (Sanatoga PA). I recently "discovered" an interesting quirk ... as it applies to my use/charges for telephone service. When I lived in DC, ALL +1 (ie LD) calls were billed to my ATT LD account. If I dialed Baltimore from Silver Spring, it was billed to my ATT LS account. I don't recall (I checked some old C&P bills) any C&P toll charges. I was surprised on a recent Bell of PA bill to find all my +1 302 (DE) calls charged to to my Bell of PA account rather than to my ATT LD account ... at a higher toll rate. Contact with Bell of PA and ATT confirmed that unless I specify ATT access code, the intra-Bell of PA call will be placed (ie AC 610 to AC 302), and charged as a Bell of PA toll charge. This moves (no pun ...) me to ask which is cheaper -- a +1 302 call via Bell of PA or ATT (using Reach-Out-America). Add to the equation the fact that most of my calls from my home are toll calls (the local joke here is all calls beyond your next-store- neighbor's are toll calls) and my Bell of PA bill is about 30% higher than my C&P bill ... excluding the LD toll charges (ie to AC 302). Life (as it applies to Telephone service) was truely simpler before Judge Greene.

It is said that the user group wanted a unified nine-digit numbering scheme. Oddly enough, France has roughly the same number of telephones as the UK; but the UK is about to change from a 10 digit scheme to an 11 digit scheme. I somehow doubt if the North West France zone will be given code "5"; because that would entail callers dialling 05 to call NW France. At the moment 05 is the French toll-free code, the equivalent of 1-800 and 0800, which they call "numberos verts" - green numbers. The French 05 will, I am told, in due course change to 0800. A separate code (06?) has been allocated for mobiles.

I thought I'd post again ... Our company has the main facility in Ventura, CA, and we have smaller sites throughout California. Right now, we're just using regular phone lines to connect to these facilities for voice. For data, there's a T1 going from the Ventura site to the long distance carrier POP, and they run 56Kb circuits to each of the remote locations. We're currently using only seven channels on the T1, and expect to have a total of 12 in use by the end of the year. I'd like to know how complicated it'd be to use the remaining twelve channels for to route voice calls to our remote sites. Ideally, the extensions at the remote sites would look like regular extensions to everyone else in the network. Some technical details: The main facility has an AT&T System 75 switch. The remote sites have their own switches, though not all of them have the same model (or brand, for that matter). One of the facilities doesn't even have a switch, just three lines in a rotary (our smallest site). Thanks! Javier Henderson henderson@mlnaxp.mln.com ------------------------------ Date: Sat, 15 Jan 94 14:11:03 PST From: tedh@cylink.COM (Ted Hadley) Subject: Wanted: Reverse Phone Directory I have a (hopefully) simple request: Is there a simple (and low cost) method of converting a residential telephone number to the name and address of the 'owner'? I called the public library and they had no such directory. I have two numbers I would like "reversed"; both are local to the San Jose, CA, area (one is Mountain View, the other is Sunnyvale). Please E-mail responses. Thanks much. Ted A. Hadley tedh@cylink.com [TELECOM Digest Editor's Note: The simplest and least expensive method would be to call one of the three libraries in the communities mentioned above and ask to speak with the reference librarian. Tell that person you need a couple lookups from the criss-cross directory. If they are not busy they will probably bring the book to the phone and read from it to you. You did not say which library it was that you called who told you they did not have such a book, but I'd be quite surprised if the San Jose library did not have one covering the immediate region. Almost all public libraries have a criss-cross directory at least for their own service area. Maybe the person who answered the phone mis- understood you (if you called one of those three). Ask specifically for connection to the reference librarian or the reference desk first. There are a few libraries whose board of directors has passed a rule against reading to patrons over the telephone from the criss-cross; usually these are cases where some deadbeat has been located by a collection agency via a phone call to the local library reference department to track down a phone at the address in question and the deadbeat has then called the President of the Library Board raising cain about 'violations of his privacy', etc ... rather than bother with defending their right to speak public information and having to choose between which patrons to offend (local service area people or the out of towners who want to use the criss-cross) the Board may just say to heck with it and tell the librarians to not quote the book over the phone any longer. It goes against their grain to ban the book entirely, so the compromise for those libraries is that people who want to use the criss-cross have to come in personally to see it. For some libraries also, it is an administrative problem: some libraries get literally *dozens* of telephone calls daily just for the criss-cross book alone; the Chicago Public Library has a telephone line and a full time employee for just that purpose -- taking calls of the 'will you look in the criss-cross and give me the phone number and residents' names at XXX ZZZZ Street.' When you call, the line is always busy as the woman gets several dozen such calls every day of the week. Some libraries get more long distance calls each day from out of town people (frequently collection agencies and other investigators) asking for information from the criss-cross than they do local calls from their own service area patrons about other reference topics. By the way, if it is a large library in a bigger town, try asking the switchboard to connect you with the 'Business and Technology Department'. They nearly always have a local criss-cross as well. A five minute or less phone call that costs about a dollar will tell you all about the address or phone number you want. No need to use fancy services or pay big $$.

I had a few questions about the intersection of ATM and DSP architectures and algorithms. Here they are: 1. What are the typical algorithms used in processing of full-motion video, images and audio packetized into ATM cells of 48 bytes? In particular, how does this level of packetization affect the signal processing steps undertaken and the architectures that perform these steps? Of course compression/decompression algorithms are important, but other than that, how about algorithms arising out of user-interaction and manipulation? In other words, if the flow is not directly from the source to a rendering device like a monitor or a speaker, what are the important classes of algorithms? 2. Is there any literature on this topic, that you would care to recommend? Survey papers accessible to non-DSP-type but technical people would be perfect as my knowledge of DSP is limited to a basic graduate-level course. Thanks a lot.

"Custom Calling Features" includes Call Waiting, Call Forwarding, Ident-a-Call (distinctive ringing), Three-Way Calling, and Speed Calling. "Call Management Services" includes Call Display (caller ID), Call Return, and Call Screen (blocking of calls from selected numbers). And "Telemessage Service" includes Call Answer, Extension Call Answer, and Voice Mail. The classification into groups matters because it affects the charging. Any one Custom Calling Feature costs $4.00 a month (Canadian, plus tax, residence rate); any two, $5.50; any three, $7.50; any four, $9.50; all five, $11.50. Any one Call Management Service costs $4.75 a month; a second or third one is $2.25. And the Telemessage Services are similarly grouped together. In my case, I have Three-Way Calling and Call Return, and have found it annoying that there is no discount for this combination. Well, they're fixing that. All the features are being lumped under the general title of SmartTouch Services, and a simplified pricing scheme is being adopted. Call Answer, Call Display, and Call Waiting will be $5.00 a month; Extension Call Answer and Voice Mail will be classed as "options" at $2.00 a month; and all the other services will be $3.00 a month. However, each service (but not options) after the first one is reduced by $1.00 a month. So my charge for Three-Way Calling plus Call Return goes down from $8.75 to $3 + $3 - $1 = $5. I like it. Incidentally, as usual with Bell Canada, the bill insert announcing the change (which is effective January 22) is in English and French. For those who may be curious, here are the French names for each of the above services, and their translations back into English. SmartTouch Services services Etoiles (Star Services) Custom Calling Features (The French version of the brochure Call Management Services uses no names at all for these Telemessage Service groups of features) Call Waiting Appel en attente (Call in Waiting) Call Forwarding Renvoi automatique (Automatic Resending) Ident-a-Call Appel personnalise (Personalized Call) Three-Way Calling Conference a trois (Conference of Three) Speed Calling Composition abregee (Abridged Dialing) Call Display Afficheur (Poster) Call Return Memorisateur (Memorizer) Call Screen Selecteur (Selector) Call Answer TeleReponse (TeleAnswer) Extension Call Answer TeleReponse multiusagers (Multi-User TeleAnswer) Voice Mail TeleCourrier (TeleMail) Mark Brader, SoftQuad Inc., Toronto, utzoo!sq!msb, msb@sq.com ------------------------------ Date: Sun, 16 Jan 94 12:15 GMT From: Richard Cox Subject: Free Local Calls Reply-To: mandarin@cix.compulink.co.uk mzmijews@mgzcs.demon.co.uk (George Zmijewski) said, referring to the UK: >> the idea of free local calls is unknown here. :-( That's not quite true. "Bundled" local calls (nothing is *ever* free!) have been available for some time in the independant Grand Dutch of Hull. We discussed Hull's special status in the Digest some time last year. Now the new "local-loop competitors", the Cable TV companies, are starting to offer their customers free local calls within their system ... but of course calls to other phone companies' customers are chargeable. And in a surprise move late last year the Mercury One-2-One service (A PCS service operating to the DCS 1800 standard) now offers customers on its domestic tariff free local calls in the off-peak period. These calls really are free, even though they are mostly to customers of BT ! As a result the service has been overwhelmed with customers despite what is reported to be less than ideal radio coverage, and a limited service area.

What you may be subconsciously reminded of is the embarrassing series of Infiniti car commercials back when the marque was first introduced. Rather than show the car, the ad agency decided to show soothing pictures of waves. That was all. Rather than provoke curiosity about the car, it raised questions about the competence of the advertising agency. ("Dammit, Bruce, I _told_ you the tide was coming in!" -- Dave Barry) Having seen at least two equally-uninformative commercials featuring the mystery girl, I share your puzzlement. One of the ads ends with an unexplained freeze-frame closeup on her reciting the name; the image freezes in midsentence while the soundtrack continues, truly a jarring sight to no apparent effect. More to the point, it appears MCI is aiming at a audience sophisticated enough to understand new product information, but MCI doesn't seem to realize that this same audience will tune out nonsense messages where no information is really there. The conclusion I draw is, "MCI has blown a ton of money on this, with no clear idea of what they want to say. This does not give me confidence in the company." AT&T, Ameritech et al have all had their share of annoying commercials, but at least you get a sense of purpose from them: "Here is our product; this is what it does; would you like to buy it, please?" MCI's message appears to be, "How do you like my hat?" Andrew C. Green Datalogics, Inc. Internet: acg@dlogics.com 441 W.

The telcos are in business to do one thing and one thing only. What's that? to provide phone service? BZZZT. wrong answer. They are in it ... TO MAKE.MONEY.FAST. (with apologies to David Rodes ...) They will configure the rates in such a way as to maximize their revenue. Pure and simple. Now in many cases this will also help people reduce their own costs. For example, The Telephone Company way-back-when realized that their 'long distance' equipment sat idle after business hours, and that it cost them a -LOT- to add capacity for that 2:15pm surge in calls, so they put in discount rates for after hours. This helped shift some usage away from peak daytime (which lowered their costs) AND brought in 'found' revenue by increasing the number of discretionary calls. If the 2:15 pm load was 10% higher, then they'd need more physical plant, and would (almost justifiably) have to raise rates as well. OTOH, most of the incomprehensable rate plans they've implemented have been designed solely to increase revenue, WITHOUT doing much good for the customers. For example: Here in NYC about 15 years ago NY Tel eliminated free directory assistance calls. Instead, tehy gave a ?50 cent? credit and offerred six free calls/month. Calls above the six would be $0.25 each (quantity and rates approximate from memory). The idea, they claimed, was that DA calls cost the company, and by extension the customers (never the shareholders, by the way) money. People who 'abused' DA would get charged and everyone else would benefit. Of course we've seen the credit disappear, and we've seen a complete elimination of any free DA calls ... I could go on and on, but the key point to keep in mind here is that the telcos are a business, not a service, and want to enhance their money streams. In -some- cases a general good comes of it (off peak pricing) but in most cases the only benefit is to the company. (or should that be The Company). dannyb@panix.com (or dburstein@mcimail.com) (10288) 0-700-864-3242 ------------------------------ Date: Sun, 16 Jan 94 16:14 PST From: rlm@helen.surfcty.com (Robert L.

[deletia declaring modem users a small minority who will get squeezed by per-minute rates] But the question in my mind is this: is it *really* the case that modem users are that small of a minority that they wouldn't be able to resist this sort of thing? It's happened slowly and quietly, but there are a *lot* of homes with personal computers in them. A goodly number, and I would bet a majority, have modems. In California, digital data service is coming in the guise of ISDN, or SDS as Pac*Bell insists on calling it. This digital service will not carry the 500 channels of one-way television that the cable companies and the telcos want to believe will drive their stillborn idea of the Data Superhighway; but rather, it, and its successors, will spark a far superior way of communication: e-mail, digital voice-mail, and tons of other digital services. In other words, the Data Superhighway will be a many-to-many network of peers, not a one-to-many broadcast network for The War Channel, Duck Hunting Network, and Macramevision (although this isn't entirely beyond the pale). By some estimates, as much as 50% of the existing traffic on the telco networks is data. If digital services are offered at reasonable prices and terms, there is absolutely no doubt that they can spur a *real* revolution in communications. Obviously, for Pac*Bell to offer ISDN now seems to me to say that they think there's enough people out there with modems who want this service that they'll succeed. I think they're right. ------------------------------ From: dold@rahul.net (Clarence Dold) Subject: Re: Shannon's Law (was Re: Hayes' New Modem) Organization: a2i network Date: Mon, 17 Jan 1994 01:34:56 GMT Of course, in the good old days, of printing _checks_ on a serial printer, hanging off a terminal, you would always overstrike the dollar amounts.

That error might have been Goldstein's or it > might have been mine. Regrets extended. Your editor, Murphy.] I'm the one who originally posted this question, for those who don't know. It's nice to know what Shannon's law says -- if you assume a 30 dB SNR and 3100 Hz bandwidth, the law above works out to about 31 kilobits per second. If you happened to get a quiet channel, say, 40 dB SNR, the equation returns about 41.2 kilobits per second. However, this is still quite a ways off from a full-duplex, 28.8 kbps link, or 57.6 kbps total transfer rate. So my question still stands: How do they do it? Are they assuming a particularly quiet channel? Are they assuming more than the standard 3100 Hz of bandwidth is available?

(mostly) Sorry, but when you use ISDN to place a B-channel data (non-packet) call, you have a data path reserved through the network for your call, just as in the case of a voice/modem/FAX call. At least as much equipment is needed for such a call as for a voice call. Sometimes supporting ISDN data requires equipment replacement or updates, adding to the costs of ISDN. > That of course didn't phase them.

Some consumer groups will support the retention of flat-rate voice calls in various areas. I know of none that advocate the funding of ISDN deployment by placing those costs into the general rate base (forcing all telephone users to fund ISDN "free" data calls). And if cost recovery is only from ISDN fixed charges, very few customers will want ISDN. Who do you want to fund your "free" data calls. > [Side note for those keeping score: US West in Portland offers 2B+D > for $90/month, no limit on data. Of course, you can't make an ISDN > data call between GTE and US West just yet, but they're working on > it.] This is difficult to believe (but possible) that such data calls cannot be placed, since most US West and GTE areas support Switched 56 calls. ISDN B-channel data calls rate-adapted to 56Kbps are almost identical to and interwork well with Switched 56 calls. The Switched 56 dialing plan usually uses '#56' as prefix digits to let the CO know you aren't making a voice call -- with ISDN, this information in in the SETUP message from the customer's ISDN equipment. The interworking also allows 56K calls from ISDN customers to reach other countries that do not yet have ISDN in place.

The information is supplied by Bell Communications Research and various Operating Companies and is updated periodically as new information becomes available.

Even if you get charged that for eight hours a day, it's minor. Check the math -- a typical eight-hour-a-day work-year is 2000 hours. $4.00.hr would be U$8,000.00. Since the U$65k S+B package you mention really works out to about $35-$40k/year take home for a family, this would be 20-25% or about the same as a typical house payment. Besides, it is not the highest paid employees who would be the best candidates nor the largest group, it would be the lower level clerks, secretaries, accounts receivables, accounts payable, etc. employees who would make up the largest and best group. For example, it would not particularly benefit me (though I do a lot of things work-related from home) since it it usually the obscure things that require hands-on that I do. It would not be practical for me to have a full laboratory at home (though some say that I do already), however for someone who does all of their work with a terminal and a telephone already, it is very viable. > Most employees who would best benefit from telecommuting are the ones > who are well into long-distance calling areas. Disagree here also. Metro commuting is what takes the most time and LATAs are getting very big. I live 23 miles one way from my desk and it is a local phone call. Metro commuting is also what takes the most fuel and creates the most congestion. > And who knows -- I don't follow ISDN or related services too closely, > but it (and similar services) will become more widely available as the > cost of bandwidth falls. Don't hold your breath. Orlando is often touted as one of the cities with ISDN available, but the last I looked it was confined to a very small area that was not at either my workplace (10,000 employees) nor my home.

I had to jump thru hoops to get an answer to my question: "Why is it that I can't send faxes to my computer when my voice mail system is running?" The answer: Prometheus' software, when it is running the voice mail mode, cannot recognize the tones from certain fax machines ... if you're not going to be sending faxes to the computer, you might want to take a chance, but I just want you to be aware of that limitation.

It seemed to me that a hands-free telephone would have a dramatic effect on productivity, but I never found the right phone for the job. A few months ago I saw an advertisement for a thing called the Ear Phone, made by Jabra Communications Corporation (I have no relationship with them) which is a small device that fits in your ear (like ear-bud headphones) and functions as both microphone AND headset. It can plug into a regular telephone headset jack, a personal computer (for voice control or annotation) or a CELLULAR PHONE. I haven't tried it out, but this sounds like a really cool application.

Note the 300 > to 3400 Hz nominal frequency range; the 3400 is a hard filter. The anti-aliasing filters used to be at 3400, particularly when they were implemented using passive-filter technology. Today, the modern line cards are using digital filtering or active filtering (using op-amps) and the anti-aliasing filters start having their effect at 3700 Hz. Draft Recommendation V.34 makes used of the extended bandwidth when available in selecting the symbol rate to use on a connection. The added benefit of shifting to a higher symbol rate ("baud" rate to you old-timers) is that the Draft-V.34 modems can try to avoid a low-frequency distortion problem caused by the transformers on certain line cards without having to shift down in speed. When looking at the Shannon limit, you have to look at more than just added noise in the channl. There is also noise caused by intermodulation distortion which seems to be nigh near impossible to remove from the network. The "rule of thumb" is that the quantization noise of a companded telephone channel is equivalent to 39 dB SNR for a single PCM channel, 36 dB SNR for two tandem (unsynchronized -- don't ask) PCM channels, and 34 dB SNR for three tandem PCM channels. Digital speech compression just adds to this, although I don't have number for it all.

(Maybe > some AC's are so big one recording couldn't handle it?) Well, over here in 414 (Milwaukee and it is COLD!), Ameritech/Wisconsin Bell (when it was still around) has the whole 936 exchange set aside for weather (936 = WE6 = WEather). You can dial any number in 936 and you get the current weather forcast etc. It also has the whole 844 exchange fot time (844 = TI4 = TIme). It's been this way for as long as I can remember. I kinda figured that all AC's had it set up this way. It seems very logical, oh well, go fig. (And Milwaukee's probably even worse ... snow (two to five inches) and below zero temperatures. UGH!) [TELECOM Digest Editor's Note: We 'warmed up' today here in Chicago; all the way to about ten degrees! Sunday evening we started getting the same snow however and by Tuesday we are supposed to get the sub- zero temperatures again. For quite a few years here we had WEAther expressed as 932-1212 (WEA) then it went to 934, and later to 936. For a few years now it has been a premium service on 976. As 932/934/936 it was always the sole occupant on the exchange; you could dial any number at all and get weather. Not so with the Time of Day however. For umpty-dozen years it was on CAThedral 8000, aka CAthedral 8-8000. It was the only occupant of CA-8 (228), but 228 itself simply trans- lated into DEArborn or DEarborn 2-8000 where a block of a couple hundred numbers upward from there in rotary hunt would provide the time of day. Now they even have that on a premium 976 number! I simply use the one provided by Central Telephone Company (aka Centel in Park Ridge, IL) at 708-296-7666 for the time of day and temperature. Does anyone remember when the Time of Day in New York City was NERVOUS? Do they still have that one going? The weather forecast for London, England made the most sense for quite a few years. One simply dialed WEATHER. I never did know why in the USA they always insisted on using 1212 as the suffix. PAT] ------------------------------ Date: Sun, 16 Jan 1994 16:43:21 EST From: Peter M.

Sorry, but it is the customer who pays the bill, not the employee of the customer. What is done with that information is up to them. Cannot talk about other countries but at least here in the US a person generally has a right to know what he/she/it/other is being charged for. Of course nothing is stopping anyone from purchasing a pen recorder (several are available) and putting it on *their* line, the major privacy issue seems to be that the employer may have some difficulty if the employees are not told, but and again in the US, property laws are still the foundation of our society.

Don't have the number handy but you can get it from ... An interexchange carrier I've worked with in the past obtains their tariffs on CD-ROM (monthly replacement set, weekly update CD-ROM) from a company called Communication Image Technologies, Inc. (CITI). CIT's application works with a set of 12 CD-ROMs, a special application which facilitates the searching and retrieval, setting tariff marks to check for updates in important tariffs, etc.. By purchasing the system and service, they've replaced a 12x14 room of bookshelves for tariffs (which were impossible to keep updated; took one full-time clerk to maintain) to a 486/33 workstation and 12 CD-ROMs, running Windows and CITI's application. The application was easy enough to allow anyone in the office to quickly retrieve the information they need. Tariffs stored include not only interstate FCC tariffs (AT&T FCC1, FCC2, etc. even including contract tariffs!, MCI, Sprint, LDDS, Worldcom, and other smaller IXC's, RBOC tariffs for switched/special access, Independent LEC tariffs incl. United, GTE, Lincoln Telephone, etc., and Intrastate tariffs including switched/special access, business service, residential service, special products (ISDN, Frame Relay, Information Services)). Overall, my impression was that if you need current access to telecom tariffs, this system is an exceptional resource. Contact information for CITI: 800-944-CITI (800-944-2484).

If you are talking about non-commercial data transmission (personal, scientific, etc.), then you should contact the American Radio Relay League (ARRL). A 20 M band packet setup could (when propagation permits) provide you with the service you need. All that is required for this is a good ham radio rig, and a packet radio modem (called a TNC).

A thread on the WELL indicated that Cable & Wireless always passes the CNID (calling number ID) field to the receiving LEC's SS7 network, which then passes it to the subscriber if Caller-ID-enabled. AT&T does not pass this field through. In a legal matter in which I am involved as counsel, AT&T has admitted that it gets the CNID from the originating LEC and strips it out unless it is paid to pass it through; however, they don't apparently have a tariff to charge for the pass-through. Interestingly, it seems it may cost AT&T more to strip it out than to pass it through. Michael D.

Not necessarily. I live in Baltimore, Maryland, where most Welfare recipients receive their benefits via these methods. You don't need an account with a recognized bank; the local Welfare office issues a recipient an ATM card and a list of distribution dates. The recipient can make unlimited withdrawawals/balance checks of the funds remaining in his/her "account," from *any* machine equipped to deal with the cards, at no charge.

McMillin) Subject: More on the LA Earthquake At about 4:35 AM, Los Angeles suffered an earthquake of magnitude 6.6 on the Richter scale, centered in the San Fernando Valley. Phones and electricity were reported out throughout the entire Valley. Major fires started by gas main ruptures have been reported, and at least four large apartment complexes have burned completely to the ground. Valley residents will probably report this with more harrowing detail that I can. Los Angeles Mayor Richard Riordan announced one death on the freeways caused by today's earthquake, but failed to say where or which freeway. Interstate 405, the main coastal artery, has suffered extensive damage in the Valley, and is completely closed. In fact, except for one, all freeways in the San Fernando Valley are closed. Los Angeles International Airport is closed. Details as they come in. Robert L.

A total mess, but still here. Power just came back and I just managed to bring up the main systems. Miraculously, the routes back to the net are up. More details later. Basically, much of the region is still w/o power and water. I have water in theory, but the main broke so I can't get at it. The valley is still largely black -- I'm amazed this area came back online as soon as it did. Phones stayed up pretty much throughout, with only the usual overloading problems. Definitely the worst I've been through in my lifetime here. Much worse damage than '71. --Lauren-- [TELECOM Digest Editor's Note: Please keep us posted whenever you can with more details.

Fine. I fit the bill perfectly. I'm a communications (specifically *data* communications) professional. I'm busy. Let's get to the frame relay. Not so fast. First, we have an introduction that wants to tell me I should be interested in frame relay. Look, I got the book, didn't I? Then, we have a chapter one which wants to tell me what a "protocol" is, and about packet switching. Pack it in, guys: I'm a professional, remember? Then, we get another *two* chapters of sales pitches! Buried in the verbiage, there is a *bit* of information about frame relay: - it has higher throughput than X.25 (how? less error correction and recovery); - you can connect anything to it (how? probably the same way you do now-- with difficulty); - you can connect voice to it (maybe. or maybe that's *cell* relay, or ATM); - it has faster response time (how? don't know); - it has higher throughput, again (how? by letting you use more bandwidth, if it is available. Huh.) On the other hand, it takes less than an hour to read. copyright Robert M.

Only the names were changed to protect the innocent". My mother is Manager of a credit union in one of the small cities adjacent to Newark, NJ. The office is on the ground floor in a mixed use area (street level business, upper floor residences). In addition to herself, there are two part time employees. They have two or three phone lines coming in. The local phone company is NJ Bell, and AT&T is their long distance carrier. One day, a NJ Bell service guy showed up. After checking with her employees, my mother informed him that no one had called for service, and that everything thing was ok. In a later conversation with her computer service company, it turns out that they had called NJ Bell, as they had had difficulty reaching my mother's office one day after hours. The computer service claims to have gotten some sort of circuit failure intercept. A day or two later, my mother was working late (there's a lot of extra work this month generating 1099 forms and such). At one point, my mother picks up the phone to make a call, and finds a conversation in progress. Her first reaction was to hang up. After thinking about it for a minute, she realized that she was the only person in the office, and that the lines couldn't be in use. At this point she picks up the line, and "This is the Credit Union, may I help you?". One of the people on the line mumbles something like "isn't so-and-so there?" and hangs up. My mother then hung-up and was able to use the line to make her call. The next day, she reported this event to NJ Bell. A day or two after that, one of the phone lines went dead, and again NJ Bell was involved. As you might expect, the next phone bill was quadruple the normal. Most of the "mystery" calls were to Manilla (sp?), and a few to Panama. This is where things stand for the moment. I'll report further on whether NJ Bell/AT&T give her a hassle about the bogus charges, and how long it takes to clear the "unexpected" connections. This is the second time the credit union has been targeted for phone rip-off. The earlier incident involved improper third-party billing. (Even though NJ Bell claims to only allow third-party billing after voice confirmation, the bogus calls still occurred). In that incident, NJ Bell added third-party blocking to the Credit Union's lines, and both NJ Bell and AT&T removed the bogus charges without question. Retribution may harsh if the parties involved are identified, as the name of the credit union is "The xxxxxx Police and Firemen's Federal Credit Union". I think if I lived in a city, that would be the group of people I'd pick on ... There have been numerous reports here about unscrupulous persons making their own connections to other people's phone lines. The person (or persons) involved here seem to have known that the lines they "borrowed" were from a business, and what the normal working hours for the business were. Only a few late nights led to the discovery of the problem before the first bill showed up. Is there a way a small business can protect themselves from this, or do we all have to rely on the phone company straightening things out afterwards? Dave ------------------------------ From: chatcher@world.std.com (Charles M Hatcher) Subject: Cost of GTE Dialup Lines Organization: The World Public Access UNIX, Brookline, MA Date: Mon, 17 Jan 1994 19:56:00 GMT I'm installing some dialup lines for a modem pool in an area served by GTE South and I'm trying to figure out the most cost effective way to order the lines. A normal business line in this area costs about $52 per month flat rate. GTE doesn't offer measured use lines here. In addition, to set the lines up on a rotary will be $21 per month per line extra. As far as I have been to determine, in talking to GTE and looking through their tariffs (which I admittedly don't have a complete grasp of) there doesn't seem to be a cheaper way to go. If I install 96 lines, the cost will be about $7000 per month plus tax. My question is this: Am I missing something here? Is there a way to get lines at a lower rate? The lines need only be inward-dialing (no calls will be made from them) and I don't need any PBX-type features. All I need is a group of lines that can answer a single dialed number. I'm willing to take individual lines or T1 multiplexed lines. Anyone have any experience with GTE's tariffs? Thanks in advance!

It's nice to know what Shannon's law says -- if you assume a 30 > dB SNR and 3100 Hz bandwidth, the law above works out to about 31 > kilobits per second. If you happened to get a quiet channel, say, 40 > dB SNR, the equation returns about 41.2 kilobits per second. However, > this is still quite a ways off from a full-duplex, 28.8 kbps link, or > 57.6 kbps total transfer rate. So my question still stands: How do > they do it? Are they assuming a particularly quiet channel? Are they > assuming more than the standard 3100 Hz of bandwidth is available? You've got most of it, now it just remains to understand how the concept of echo cancellation fits into the picture. While the actual telephone line sees both signals at the same time, at each end, the receiver does not. The echo canceller makes an effort to remove most of the signal that had been transmitted (by prior knowledge of the transmitted signal and the reflection characteristics of the line it sees). Hence the receiver at either end sees the S/N from the other end plus the remaining noise from the incomplete cancellation of the transmitted signal. There is also a related effect from any hybrid circuitry in the box, but not to the same degree. I'm not trying to mathematically rigorous, but intuitively it has to be close to this ...

There are still some coming in, and I need time to compile them. When I can I will send you the summarized results--they are interesting. In the meantime, some food for thought: Keep in mind that I was asking about long distance. That is, it's interesting to know that you can use the power lines to connect your speakers (and how do they *do* that?), but how far can you go outside of the house? The transformers seem to pose a problem because of the high inductance. Agree or disagree? Or is it because the signal would have to be kilovolts on the line to make any detectable signal in the home? Or another reason? Are the power lines tuned to 60 Hz to eliminate high frequency noise and low frequency drift? I've seen massive capacitors in the substations, but I don't know what they do. If the lines are tuned, that would exclude telecom. Still looking for that bandwidth vs. distance curve. Can you use the same curve as twisted pair? I think not, because of skin resistance in the power line, single wire approximations, etc. However, some of these considerations may not apply to the high frequency signal. Related to the above, we know that the high frequency signal is superposed on the larger amplitude 60 Hz. However, in the transmission line, maybe they follow different paths -- can this be? Is the current path frequency dependent? Thanks for the help!! ------------------------------ From: ross@turock.psych.upenn.edu (Ross Porter) Subject: V.32vis -> Bell_102 Due to CO Data Compression Date: 17 Jan 1994 22:14:53 GMT Organization: University of Pennsylvania, Department of Psychology A few days ago my father-in-law reported that he could no longer get a V.32bis connection between his Gainesville home and the University of Florida's modem pool. 1200bps (Bell 102) was the best he could do. He of course initially suspected his own equipment, but he later learned from the data center staff that a number of other people suddenly developed this problem. The local telephone people reported that they had recently installed some data compression equipment that could well cause this problem. Since voice traffic is relatively unaffected, the phone company politely abdicated any further responsibility. Could someone speculate and enlighten me as to what kind of data compression is being used -- is it lossy (given the large drop in maximum transmission rate)? I am not unsympathetic to the telephone company's position, but does anyone have suggestions for lobbying the telephone company?

TELECOM is a truly international event. TELECOM 91 attracted over 130,000 attendees, 850 exhibitors, and 1700 press representatives from 164 countries. TELECOM 95 will take place in Geneva, Switzerland from 3-11 October 1995 and will comprise an Exhibition and Book Fair, Strategies Summit, and Technology Summit. The Technology Summit will, for the first time, provide an interactive arena for users, traditional telecoms companies, computer and consumer electronics giants, broadcast and cable television interests, and entertainment and software companies. This Technology Summit will present keynote speeches, discussion panels, and session papers representing state of the art or new visions of technology, services, and applications. Thousands of leading users, managers, scientists, and engineers will attend. Given the rapid convergence of technologies and the need for timely solutions, this is an opportunity not to be missed. The theme of the Technology Summit is: "Convergence of technologies, services and applications". THE NEW TELECOMMUNICATIONS ENVIRONMENT A new communications industry is emerging. Computers, networking and software are already key components of telecommunications. Broadcast, entertainment and consumer electronics industries are now also important players. The Technology Summit of FORUM 95 will address this re-balancing. As examples: * Portable computing and mobile communications are both targeting a mass consumer market. * The entertainment industry is seeking delivery of interactivity and broadband services to the consumer. * Business users are demanding seamless and cost-effective wide area networks to link their local networks. * The integration of highly complex functions on a single chip is creating paradigm shifts in all related industries. * Designing applications has emerged as the challenge of the future. Because technological solutions cannot be divorced from developmental, social, economic, and environmental issues, the Technology Summit also welcomes applications contributions from these related areas. TECHNOLOGY SUMMIT - MAIN TRACKS Featuring papers that will focus on applying technology and creating applications in this cross-sectoral environment, the event will be structured on three levels of human communication needs: 1. Communications services for the individual 2. Communications services for business 3. National, regional and global issues TRACK 1 - Communications services for the individual This track addresses voice, text, data and video communications services for individuals whether at home, at work, or on the move. The aim is to attract contributions from consumer, entertainment, computing and software businesses, in addition to the telecommunications business on: * Personal and personalized services, including personal number and mobility; * Entertainment services provided on cable television or telecommunications-based systems; * Networked computing applications; * Mass market consumer technologies and applications (inexpensive, easy to use, pocketable); * Personal assistant, telemedicine, tele-education, teleshopping, home security, support for disabled people and the elderly; * Broadcasting and other information/entertainment services including cable television and interactive broadcast services; * Wireless technologies and applications. TRACK 2 - Communications services for business This track addresses higher performance networks, distributed computing and information systems which are enabling improved services for business users and which are becoming increasingly market specific. It seeks papers which report experiences of the new "telebusinesses" e.g. medicine, finance, telemarketing, telelogistics, as well as papers on new developments in the enabling technologies such as: * Computer-supported cooperative working, including desk top videoconferencing. * Security, privacy and authentication. * Network management, intelligent networks and virtual networking. * Network interoperability, availability, and reliability. * Broadband communications. * Intelligent information services. * Enterprise and corporate networking. TRACK 3 - National, regional and global issues This track addresses issues of general interest of telecommunications, including the view on economic and regulatory aspects and their inter- relationship with convergent technologies. The aim is to attract contri- butions from telecommunications experts as well as from economists, regulators, and other governmental agencies in such areas as: * Regulatory aspects of portability and interconnection of services, e.g. numbering, billing, security/privacy, frequency allocation, etc. * Environmental applications, e.g. teleworking, teleconferencing, traffic and fleet control, telesurveillance, etc. * Restructuring of the telecommunication sector and service evolution in developing and developed countries. * Cross-cultural applications, e.g. real time interpretation, voice recognition and synthesis, conversion between text, voice and picture based services, etc. * The implications of regional standards and trading organizations. * The implications of convergent industries and technologies. GUIDELINES FOR SUBMISSION OF PAPERS: * Papers should give an overview of the present situation and/or the direction for the next century. * Papers on detailed theory and specific products, or company presentations, are outside the scope of the event and will be rejected, as will those which are overtly commercial or which treat military subjects. * Papers must be unpublished and based on original research, developments and approaches. * Papers delivered in the Technology Summit will be published in the Book of Speakers' Papers. Written contributions to the panel sessions will also be included in the Book of Speakers' Papers. Additional papers will be selected for publication only. Authors are requested to submit a one-page (single-sided) abstract of their proposed paper to the TELECOM 95 Forum Secretariat as shown on the attached form. Abstracts must give a clear indication of the paper's contents. Abstracts must be submitted in one of the conference languages which are English, French and Spanish.

INTERNATIONAL TELECOMMUNICATION UNION The ITU is an inter-governmental organization, within which the public and private sectors cooperate for the development of telecommunications and the harmonization of national telecommunication policies. The ITU adopts international regulations and treaties governing all terrestrial and space uses of the frequency spectrum, as well as the use of the geostationary- satellite orbit and develops standards to ensure the interconnection of telecommunication systems on a worldwide scale. It's 182* Member Administrations, and the much wider network that forms the ITU family, are proud of the ITU's record of achievement in keeping pace with technological change. With this goal in mind, and also to keep up with the convergence of technologies, the ITU has been restructured, with clear objectives outlined for each of the three new Sectors: Radiocommunication, Standardization and Development. * as of 12 November 1993 7th WORLD TELECOMMUNICATION FORUM President Dr. Pekka Tarjanne, Secretary-General of the ITU Chairman, Management Committee Mr. Tom Dahl-Hansen, Executive Director, TELECOM Project Manager TELECOM 95 Mrs. Lili Rison Project Officer Technology Summit Ms. Elizabeth A.

Today at around 4:30 AM a 6.6 magnitude shock occurred on either the Oakridge or Devonshire faults. Both of these faults are apparently planes which are offset 30 degrees from being parallel to the ground underlying Northridge, California, unlike most faults which are perpendicular to the ground surface. My house is located in Encino which is about ten miles south from Northridge. I was awakened by a series of sharp jolts followed by a series of rolling motions which gradually tapered away. Minor rolling motion aftershocks continued almost continuously for the next few hours. Thereafter aftershocks continued during the day at times including at least five which were over 5.0 in magnitude. My house is on the mountainside overlooking the San Fernando Valley -- after the quake the valley was pitch dark. I could not see any lights at all in the valley. In my house electricity was out for almost 9 hours -- apparently the majority of the San Fernando Valley is still without power now, 16 hours after the first shock. Phone service was out at my house for over an hour -- I still hear reports on the news that some areas of the valley are without phone service in Granada Hills and Northridge. Pacific Bell announced that incoming long distance service would be blocked during the day, and to use the phone for emergency use only. All water in LA distributed North of Sunset Blvd. is not being chlorinated and needs to be boiled. Some stores are selling bottled water for $15 per quart. The communities of Reseda, Winnetka, Porter Ranch, Northridge, North Hills, and Granada Hills have been without water all day. The water has stopped where I live at around 9 PM. Several areas in Glendale and Sherman Oaks had fires caused by broken gas mains. There is a dusk to dawn curfew in the cities of Los Angeles, Glendale, San Fernando, Santa Monica, and Burbank. Disneyland was open today, but Magic Mountain, Universal Studios, the Forum, and most of the other entertainment venues were closed. Almost all resturants were closed. Today was a school and government holiday; the majority of public schools will be closed tomorrow as will UCLA. CSUN which suffered extensive damage will be closed at least until the end of the month. Two trauma centers in the valley as well as the Olive View Medical Center, a county hospital, and the Sepulveda VA Hospital were evaculated. The Olive View Hospital was the county hospital that was destroyed during the 1972 earthquake three days after it opened and was subsequently rebuilt. A Southern Pacific freight train with several cars filled with Sulfuric acid derailed in Northridge and has not leaked any acid. There is extensive damage to the Bullocks store in Northridge, and the Interstate 5 and State highway 14 interchange. Both of those places were built recently and supposed to withstand earthquakes of up to 7.1 in magnitude. The 5/14 interchange was demolished in the previous 1972 earthquake, and rebuilt supposedly earthquake safe and destroyed today. The Santa Monica Freeway between Fairfax and La Cienega was destroyed as was portions of the Simi Valley freeway. At least five people died from earthquake related heart attacks, one lady died from a head trauma while walking after the quake, at least fifteen people died in the collapsed Northridge Meadow apartments with one other person missing. As of midnight there are 27 confirmed deaths. Many people are camping outside of their houses afraid of going back inside. Many parks and softball fields have informal tent cities set up filled with people who do not feel safe indoors at the Red Cross, or Salvation Army shelters. The {Los Angeles Times} has set up an earthquake hotline on their information newsline: 808 8463 from the 213, 310, 818, 714, and 909 area codes. Donations are being accepted by the Salvation army 1 800 725 9005 David Whiteman dbw@crash.cts.com ------------------------------ From: decrsc!leesweet@uunet.UU.NET (Lee Sweet) Subject: ISDN Primer and Video Uses Date: Mon, 17 Jan 1994 19:39:37 EST 1. Anybody know of a good primer re ISDN: uses, options, equipment required/optional? (I saw only one book at the local tech bookstore, and that was a 1/4" volume for USD 79.00 (!) with way-too-technical contents. Maybe I want Carl's _Phone_Book_ updated for ISDN ;-) ? 2. (1) above caused by request to immediately install two ISDN BRI [I do know these are basic rate lines: 2 X 64 kbps + 16 kbps control, right?] lines for evaluation a video-conferencing system (from PictureTel, I believe). Question: Is ~128kbps enough for usable video? I though good video needed at least T1-level data? I believe the application is for consulting, which needs much more detail than just showing the 'talking heads'. 3. Can I assume that the twisted-pair we have installed is fine for ISDN? It works for 10base-T ethernet, so ... should be fine, right? All comments welcome!

Guthrie) Subject: ISDN NT1 Power Source Date: 17 Jan 1994 22:04:29 GMT Organization: Vorpal Software I'm looking for a couple of answers about some ISDN questions that experience and Stalling's ISDN book have both left me unclear on. First, a CPE can be line powered (the AT&T 7506 e.g.), but my experience with NT1's are that they must be DC powered (but I've only dealt with rack mounted units). Can NT1's be line powered? Next, where are the RBOCs putting NT1s for normal residential ISDN hookups? Since the U interface range is much longer than the T interfaces, it would make sense to put NT1s at the customer site (especially for multipoint ISDN hookups, which shorten the T interface). Is this being done in practice? My reasons for asking about this are to determine whether ISDN residential lines are "lifeline" capable in all cases. I.E. can they make outgoing operator and 911 calls when powere to the residence is out? Thanks for any information, Paul Guthrie paul@vorpal.digex.net ------------------------------ Date: Tue, 18 Jan 94 07:12:24 CDT From: John Hildebrand Subject: Digital Equipment and USA Video Sign OEM Agreement Edwin Molina Sr VP of Marketing USA Video Corporation 800-625-2200 Tom Madden Digital Equipment Corporation Storage Business Unit 508-841-5365 Digital Equipment and USA Video sign OEM Agreement Digital Equipment Corporation announced today the signing of an Original Equipment Manufacturer (OEM) agreement with USA Video Corporation, enabling the two companies to work to increase their respective market share of the Video on Demand* industry, worldwide.

Anyone have any ideas? I need a system that can keep 12 people with voice connections. I also realize that I'm going to need 24 incoming lines to a system that weeds out busy signals, has answering machine capabilities, and such. There are companies that set it up, both hardware and software, for about 30-50K, but I think it could be done for way less."

In particular, I'm interested in reports of facility damage and traffic overloads. [TELECOM Digest Editor's Note: Someone at GTE (I won't say who, but it is *not* Steven Lichter, and I stress that point to certain GTE executives!) is sending me reports from GTE telling about their prob- lems. Just a few of their problems include: The Granada Hills Directory Assistance Office Building partially collapsed. Personnel were evacuated and DA functions moved elsewhere. At Santa Monica Toll a ruptured fuel tank has left the office with fuel all over the floor and everywhere else. On Tuesday they were waiting for Fire Department clearance to get in and begin a cleanup and restoration of normal functions there. Paccoima CO has major damage to the building. Emergency personnel evactuated the building and employees are now being let back in as needed to do what they can to restore service. San Fernando has a large crack in the power room wall and the building foundation is badly compromised. The Santa Monica 1AESSS has a leaking fuel supply, and the Sunset office in Santa Monica has broken water pipes. Bel Air, Camarillo and Ellwood CO in Santa Barbara have no commercial power and are running on generators. In Granada Hills, there was some damage to the switch resulting in blown power supplies and about half the switch had no dial tone on Monday and Tuesday. Pacoima #2 EAX is totally out of service. An emergency trailer has been set up to serve 11,364 customers. In that same office, the gen- erator was knocked off its foundation and has been damaged severely. They intend to cut lines to GTD-5 if #2 cannot be restored. The above are just a few of the problems, and apparently among the worst, although I may have overlooked some in the lengthy fax which was sent to my attention Tuesday. Even the offices not severely damaged are operating under considerable strain since nearly every office had at least some minor damage and disruption of service or record-keeping systems, etc. GTE is attempting to serve the public under extreme emergency conditions while trying to resolve their own internal emergencies as well. Coin Telephone Trailers have been set up in several of the hardest hit areas. AT&T officials have met with GTE executives and offered their full assistance with restoration efforts.

I received a message back saying "We're sorry, your call cannot be completed at this time due to the earthquake in the area". This morning around 9:30 (EST) I called again, and got the same message. I then tried the 800 number and got through. When I just tried the 818 number again, at about 11:30 EST, I got the message that all circuits are busy. Guess they're starting to let calls through again. Of course I won't try to dial again for another couple of days, so I don't tie up the phone lines unecessarily. On another note, I just wanted to mention how great technology is. I've been following the earthquake info on the Internet Relay Chat and on CompuServe. The compassion that I'm finding in both of these places is great to see. Many people are e-mailing from both in CA and out of CA getting in touch with relatives and friends for people over the phone.

What I need to know is if there is if there is any obligation for PacBell to provide us with T1's via a fiber terminal/mux and if so, where is the breakover point in T1's when this becomes the better solution ? Also, with respect to the copper trunks, is there any type of service that I can't bring in via T1 ? Right now we have seperate groups of trunks for FX, outgoing, DID, WATS, etc ...

Date: Tue, 18 Jan 1994 23:36:03 GMT I hope someone can help me with this. This is a modified version of an earlier post, with some additional definition. Thanks to the people who have responded so far. I will summarize and post the responses at a later date. I'm looking for a way to be able able to communicate with a specific serial port on a remote device, so that I can connect to a non-ip-addressable device that is connected to that port. To be more specific: I have two LANs that are interconnected via bridges and T1/FT1 WAN links. I have a PC on the remote LAN that has an unused serial port ("COM2"). I want to be able to use that port as a terminal server port so that I can connect to the (9600 bps async) console port of a non-ip -OR- SLIP device located near that PC, in this example a smart CSU. In effect we would be making the remote PC a small terminal server. It has been suggested to me that there may be software solutions to this. Windows or DOS solutions would be satisfactory. Any help or pointers to resources would be greatly appreciated.

Organization: NETCOM On-line Communication Services (408 241-9760 guest) Date: Wed, 19 Jan 1994 04:46:47 GMT My impression of several cell sites after poking around the outsides is that they are battery powered with an external connector for portable generators (not kept on site). I am curious as to how long they will continue to function if the operator is unable to connect a generator. What is the plan on charging these things-can the system operator just charge them in an hour or so and then tow the generator to another site or does it take longer? What will happen to the system if lots of these lose power? How many generators do operators generally keep on standby? There are going to be lots of frustrated reporters in LA if the cell system collapses. ------------------------------ From: alfredo@quickt2.it12.bull.it (Alfredo E. Cotroneo) Subject: Real Time Audio Compression Date: 19 Jan 1994 04:28:50 -0600 Organization: UTexas Mail-to-News Gateway I am just wondering if there is any device/algorithm which may compress audio in real time, and let say use e.g. 4 kHz bandwidth for an original audio bandwidth of 8 kHz, or likewise for higher bandwidth? To my knowledge there are such devices which compress audio signals and then transmitt it in digital form over a digital (radio, satellite or cable) link, but I never heard if that could be done over an audio channel itself. Any pointer on both digital and compressed-audio links will be greatly appreciated. Thanks. Alfredo E.

I'm certain that companies like AT&T, Northern Telecom, Ericsson, Rolm/Siemens, Fujitsu, and others have (or are working on) wireless PBX products, but I don't know who to contact. Any help would be greatly appreciated. Thanks. Kevin D. Tanner WilTel, Inc.

McMillin) Subject: Pac*Bell Permanent Virtual Connection Service Tariff I got hold of a copy of Pac*Bell's Permanent Virtual Connection tariff. These cover services that are essentially switched, high-speed data links to the nearest CO. Costs given are per end. For each access link at each location: speed monthly install ADN $50.05 $620 T1 $162.59 $1324 Note: PRICING IS FOR THE LOCAL LOOP ONLY SINCE FRAME RELAY PRICING IS MILEAGE INDEPENDENT. [RLM: Emphasis mine. What this means is that these data services are not, as full-up leased T1 is, dependent on how far you are away from the CO.] Switched data services: speed monthly install 56 Kbps $75 $375 128 Kbps $150 $375 384 Kbps $400 $375 1.536 Mbps $500 $375 For each end of the Permanent Virtual Connection: # of Data Link Monthly Rate per Connection Identifiers DLCI 1st $0 2nd through 6th $15 7th through 11th $10 12th through 250th $5 Each PVC has one Data Link Connection Identifier (DLCI) on each end. For more than one access link from a single location, groupd DLCIs by link, then calculate the charges. There is no recurring charge. For each customer: If traffic detail is wanted, charge $15 per month and $50 for non-recurring. ------------- To me, the most interesting thing is the notion of a 'virtual T1' that can go anywhere there's another virtual T1. I'm not sure how this is implemented; maybe someone from Pac*Bell would care to comment. In any event, the prices are really cheap compared to dedicated service. Robert L.

What I would like to know is about how the out of band signalling to the pay phone is done. I know that the pay phone will ground one of the lines when a real coin is placed in the phone. What I am curious about is which line (ring or tip) is grounded? Is the line grounded for the life of the call? Or is it grounded right after the phone signals coin insertion for a short period of time? How is coin acceptance or rejection handled on the two lines? Thanks for any info in advance. If anyone knows of the inner workings of Fortress Phones drop me a line.

I'd also like to know the basics about the equipment that neeeds to be in place to produce itemized phone bills. If anyone knows of good sources I will summarize and post here when I've done my research. Thanks, Pawel [TELECOM Digest Editor's Note: So far as I know, we have always had itemized long distance bills in the USA. I have seen *very old* copies of bills from Illinois Bell and its predecessor "Chicago Telephone Company" which had itemized calls. The oldest one I recall seeing (and have a microfilm copy of around here somewhere in my boxes of old historical artifacts) is dated 1910. This telephone bill from 1910 is on printed letterhead from Chicago Telephone Company; is written out in longhand in a very nice, very old-fashioned, very eloquent style and lists a call to Aurora, Illinois, some fifty miles away. You must remember that long before mechanical equipment was available to keep these records, the manual service operators wrote out all of their tickets by hand as they went along, call by call.

It will probably use a NCR WaveLAN. Are there similar facilities for a telephony type T1? I'd like to link a couple NT SL-1 switches, and T1's from our carriers range from $970 to $1270 per month. The buildings are unobstructed line of sight. (Laser has been ruled out due to possible weather related interference). Microwave has been ruled out as the line of sight crosses City Hall's front lawn, and there would be an environmental impact study which would delay implementation. The Spread Spectrum stuff used by WaveLAN and others does not require a license (which microwave does). Follow-ups directed to email; I'll summarize.

The traditional method is "Value of Service" pricing. While it is largely viewed as obsolete, especially at the federal level, it still plays a major role in local phone rates. The most notable example of this is in the way local rates are set in a flat-rate state. The monthly rate is based on a rate band, which is based on the number of lines within your local calling scope. So Nowhere Falls, with 300 phones in its local calling area, pays $8/month while Major City pays $15/month. After all, it gets more value for its local bill; Nowhere Falls customers pay lots more tolls. But the actual cost of monthly service is higher in the boonies, because the dominant expense is outside plant, and rural areas need the longest average wires. I saw a good illustration of this back in the '70s when I was working on Telephone Rate Reports. In Ohio, the highest rate band for (I think) United Tel (Lima) was something like 50,000 phones. For Ohio Bell, though, that was a fairly low band. So Lima customers paid something like $16/month while a Bell customer in a similar town would pay maybe $10. Columbus customers would be in OBT's higher bands. United thus had to subsidize its huge rural territory (its own cheaper bands) with small-city customers, while OBT had big cities to do it. Overall, Ohio Bell was much cheaper, but it wasn't because United was inefficient. Charges for touch-tone are, of course, another "value" element not related to cost. They add revenue to the system in lieu of collecting full cost from everyone. Rural customers need a subsidy (in order to have universal service), but things get out of hand when the system loses sight of cost. Telephone service isn't like electric service. A drop line to the street doesn't cost the electric company much; their expense is mostly in the generation, which is consumed by usage, not connections. Water used to be flat-rated in some of my area, but vastly higher costs (mostly in sewage treatment) have led to major usage-based charges. Heavy users generate more sewage, so it's fair. (Our sewer bills are on a usage basis, but use water meters as a surrogate. It's a higher per-CCF charge than water per se.) So what costs do heavy phone users incur? With older CO switches and analog transmission, heavy local usage did incur some significant expense, though never as much, on average, as the non-usage-sensitive portion. With today's costs, it's less so. A modern CO costs around $600/line with typical usage. If average traffic were several times higher (all modem freaks, etc.) then it would at most double, but more likely increase by less than that. Inter-CO transmission is also cheaper, now that fiber optics are predominant; they have nearly infiite bandwidth, though the multiplexors aren't cheap. I have no trouble with telcos charging for usage at their true incremental cost, marked up a for a reasonable (not double) profit. But that's not what local measured service plans usually are. Most make usage cover several times its fair burden, thus creating a true subsidy to light users from heavy users. Value of Service pricing never claimed to be cost-justified; it was a policy decision. Local measured usage in most cases is really a Value of Service plan disguised as cost-justified. The real numbers just don't add up. Fred R.

We're told things may 'warm Hi Pat, With regard to the international readers of TELECOM Digest I suggest that you mention which kind of degrees you mean :-) (I guess the above values are Fahrenheit.) Christian 'naddy' Weisgerber, Germany naddy@mips.ruessel.sub.org [TELECOM Digest Editor's Note: You bet they are Fahrenheit degrees! But the conditions the past three days have been even worse. On Monday the temperature hovered about about zero degrees all day and dropped to 22 degrees *below zero* overnight into Tuesday morning. Our 'high' temperature all day yesterday was 11 degrees *below zero* Overnight last night into this morning, the temperature was again about 20 below zero and as I write this, we are 'warmed up' once again to 11 below zero. It is expected we may reach zero today and after another sub-zero night rise into the teens on Thursday. Those are Fahrenheit degrees. We are all miserable. It is impossible to keep our houses warm. What I am really quite worried about is that the gas bill for January will probably be several hundred dollars and they will cut my gas off for non-payment. This is a real concern to me. This weather is the worst we have had for several years. We have many people also who try to heat their houses with little electric heaters which themselves overheat and start fires. Two nights ago a big fire started in an apartment building here due to the residents using electric heaters and 'jumping out' the fuses in the electric line in order to keep all the heaters going at one time. The wires caught fire, the building burned down. All the people went to the homeless shelters to live. :( Very bad conditions here.

Permission is granted for the entire to be redistributed free of charge as long as there is no commercial use. We also released one for Telecomworldwire earlier today. SNW-18 January 1994-BROADCASTERS REACT TO LA EARTHQUAKE- GLOBAL REPORT SATNEWSWIRE--(C) 1994 M2 COMMUNICATIONS LTD LOS ANGELES/WASHINGTON, USA/LONDON, UK- At 1231GMT yesterday (17 January) Los Angeles was hit by a massive earthquake centred 20 miles northwest of downtown LA in the San Fernando Valley. While the earthquake has killed at least 28 people with its 6.6 Richter scale shakings most of the public remain calm, TWW and SNW correspondents report at 0100GMT Tuesday. Telecommunications services throughout the area were disrupted by the early morning quake although emergency service communications on the whole remained operable. The effects of the quake on America's second city were felt as far away as Las Vegas (275 miles east). Broadcast stations were understandably busy covering the event. Interest from international broadcast stations was also high Local television stations who were able to come to air did so and even in the San Francisco Bay Area, about 400 miles north of the earthquake area, virtually all local TV stations immediately began rebroadcasting satellite feeds from the disaster zone. ABC, CNN, CBS and NBC continued live coverage although some of the local independent stations reverted back to their usual programming schedule around teatime. CNN had two of its anchors in LA by chance when the quake struck and they filed reports by phone within minutes. The other networks flew their anchors in to present the evening news shows. CNN lost power to its LA bureau and for a while reports were sent from a Ku-band uplink truck. It took Bernard Shaw about 2 1/2 hours to get his first stand-up to camera interview on air. In the race to get to air CNN was first with a report by 4.38PST, followed by NBC at 4.42 and ABC/CBS at around 7.45. In the UK ITN reported at about 1255 (4.55PST) followed by the BBC about ten minutes later. Data for Sky News is not available. There has been a plethora of news feeds carried for all of the main major networks over North American satellites including: G4/8 -- Telemundo feeds in Spanish; G4/12 -- KABC, Los Angeles; G4/17,19 -- CBS raw feeds; G3/20 -- ABC feeds; G3/11,15 -- CNN feeds; T2/10 -- ABC feeds; T2/13 -- feeds; G2/6,7 -- ABC feeds and G2/18,20 -- CNN feeds. CNN Airport Channel on GSTAR2 stopped its usual programming menu and relayed CNN live and CNN International (Ku-band) dropped Leitch encryption and went in-the-clear so that rebroadcasts of its signals can take place. CNN drew heavily on its local affiliates KTLA and KTTV for coverage, often coordinating its reporters live while on air. NBC used KNBC, ABC used KABC and CBS used KCBS. In many of the airborne news reports, there has been frequent evidence of co-channel interference on the internal TV station microwave feeds. Obviously there are so many news agencies using the limited number of channels that the field feeds suffer visible video damage and sometimes total loss. In Europe Sky News was relaying live footage throughout the day and night from Fox. The Intelsat-K satellite was used to distribute the live broadcast. The European Broadcasting Union used Intelsat 601 to link its New York news bureau to the Eurovision distribution network. Eutelsat II-F1 acted as a rebroadcast feed for Reuters Television and WTN amongst many other broadcasters. GE reports that all is well at its South Mountain Earth Station, located approximately 45 miles north of the epicentre. Although commercial power was lost all four diesel backup generators provided TT&C and Communication control of F2R(72W), C1(137W), C3(131W), C4(135W), C5(139W), K1(85W), K2(81W) uplink and monitors. "After-shocks are occurring but except for a few fallen ceiling tiles and a slightly disturbed 21 meter autotracker, we are doing fine," said Grant Koehler, a spacecraft controller for GE at the site. It appears that not all Americans sympathised with the plight of their fellow countrymen. ABC Television said that they received hundreds of phone calls that continuous news coverage interrupted their soap opera viewing. CNN was also the victim of a phone hoaxer who posed as a LA fire department spokesman who gave out a toll-free number for information. The number turned out to be a recorded order- taking service for raunchy Howard Stern videos. Bernard Shaw aired the number and subsequently apologised to viewers before hitting out at the prankster for being "not funny and in fact very stupid." *Prodigy Services Co. in White Plains established a free bulletin board system which linked Prodigy's online community in the quake area with the rest of the United States. Nearly a thousand notes were posted within hours of creation. CompuServe set aside a special forum for on-line queries and information for anguished US citizens. ------------------------------ Date: Sat, 22 Jan 1994 14:53:12 MDT From: Rob Slade Subject: Book Review: "Compuserve CIM Running Start" by Campbell BKCSVCIM.RVW 931202 Sybex Computer Books 2021 Challenger Drive Alameda, CA 94501 USA 510-523-8233 800-227-2346 Fax: 510-523-2373 or Firefly Books 250 Sparks Avenue Willowdale, Ontario M2H 2S4 416-499-8412 Fax: 416-499-8313 "Compuserve CIM Running Start", Campbell, 1993, U$17.95/C$22.95 71650.2556@compuserve.com Let's review this on the basis of the cover blurbs. "Exclusive Two-Part Format, Designed to let You Get the Most Out of CompuServe." The two-part format is a tutorial and a reference section. Hmmm. Somehow that format sounds vaguely familiar. However, if you need this tutorial to get you started, I doubt that you are ever going to get the most out of CompuServe. Remember, this is a tutorial on how to use a graphical interface, which is, itself, an aid to a menu interface. "If you want to add an address to your address book, just press the Add button when you are in the Address Book Screen!" "Nine Simple, Step-by-Step Lessons to Help Make You a CompuServe Ace." Simple? Yes. Ace? See above. Let us suppose, though, that this book is aimed at the complete and utter computer neophyte. There is nothing here about the really hard part of communications: setting up the modem and making the first few calls. "Covers both WinCIM and DOS CIM." On the inside back cover is a sample screen from CIM for DOS. There are twelve references to differences between the two versions. Otherwise, this is about WinCIM. "Special Bonus Offer! FREE CompuServe Introductory Membership Plus a $15 Credit towards Your Usage." If there is anyone who has been involved in the computer world for a while and hasn't had dozens of such offers -- how did you avoid them? Now all of this may be amusing, but is it fair to the author? After all, it is the publisher who decides on such things as the cover, and often even the title. However, what is really at issue to the "consumer" is the book as a whole. Campbell has done a reasonably good job. The material is fairly clear, and the work is well written, as far as it goes. However, the concept of the book, as a whole, is one that boggles the mind. Do people really need documentation for this? Do they need a third party book? A while back a friend and I were delving into CompuServe via WinCIM. There were a number of "features" which we thought should probably be there, but we couldn't figure out how to make it work. This book was no help either in terms of finding those features, or in terms of confirming that they were or weren't available. Third party books on systems generally either help to mitigate the shortcomings of the existing documentation, or teach more advanced "tips and tricks". This book doesn't, and there seems to be little chance that such is possible with this topic. copyright Robert M.

Cutaia) Subject: IC's For DTMF Detection Date: 22 Jan 1994 14:44:01 GMT Organization: Washington University, St. Louis MO I am interested in finding the IC's that will filter and detect the DTMF frequencies. I have read in "Understanding Telephone Electronics" that semiconductor manufacturers produce integrated circuits to provide both the bandsplit filtering and detector functions. They mention the Mitel MT8865 and American Microsystems, Inc. AMI S3525 as candidates for the filtering operation, and the Mitel MT8860 for the decoding. I have two problems. First, the book was written in 1984 and there have undoubtedly been newer versions of these IC's and perhaps more manufacturers. Second, how do I go about getting information on specifications for these IC's. I would like to know if there are newer versions of these IC's out there, and if so, who are the manufacturers. Also, how do I go about getting these IC's and how much do they cost. Any help would be appreciated. Please send responses to my e-mail.

It seems unwise (at the very least!) to spend this much when there are some available that cost you only 25 cents/minute. And at that rate they are still giving some of that back to the organization that markets them, so these higher-cost ones appear to me to be vastly overpriced. Let me update my previous (December) posting on one source; these are now advertised as being available over the phone for credit-card orders. (I have no idea why these people didn't do that from the beginning ...) The populist newspaper, The Spotlight, is selling these type of prepaid telephone cards in $30, $50, and $100 denominations. The original ad said they're good in the US and Canada, but not Alaska, but the current (Jan 3) ad says "anywhere in the USA" -- I have no idea if that means things changed over the intervening month. Calls are charged against the card balance at 25 cents per minute at all times. The ad does not state the 800 number you call to use the card. They do imply you deal with a live operator that will tell you your outstanding balance, but I suppose that could also be an automated interface. They state the card can be "replenished" by calling and giving a credit-card number to restore or increase the credit balance against which calls are charged, but I don't know if that is done through the order number (below) or through the unstated connection number, or via yet a different number. To buy these, you can call with a Visa or MC, or write them and order cards with a check (payable to "The Spotlight"), or a Visa or MC number, with expiration date and signature. The address/phone is: The Spotlight 300 Independence Ave., SE Washington, DC 20003 800-522-6292 Regards, Will ------------------------------ Date: Sat, 22 Jan 94 12:02:15 PST From: nahabed@ntmtv.com (Roupen Nahabedian) Subject: IS-54 Material Looking for references on IS-54 material (other than EIA recommendations) : publications, artciles, books, etc. Also, if you can recommend any training materials/sources, it would be appreciated.

We are trying to use Security Dynamics SecurID to do secure DISA with Centrex and have a problem. Our Centrex will not allow transfer of dialtone. If A calls box B then box B must dial the entire number. IE, the only way to connect A to C is using three way calling. What some PBX's allow is box B (or a second person) to and give dialtone to user A. Does anyone know if any Centrex's allow dialtone transfer and if so, what is the magic jargon phrase I need to tell our telco rep? This is a DMS-100 switch, if that makes a difference. The other way the box works is by connecting a user to a modem. The second port on the box sends a ring-signal to a modem which then goes off hook. Is there a voice equivalent box (besides an answering machine, of course) to a modem that will pick up a line on ring signal and connect thru? I assume if such exists it is used for some other purpose but anything I can coerce into doing what we need would be very useful. Thanks in advance. Jerry M.

The modems themselves will be in the Berwyn exchange in Maryland -- area code 301. However, we want to have a 202 dialin number for DC users (mostly for marketing purposes; we realize that Berwyn is not a toll call from 202). We need to support a peak of 20 simultaneous dialins, and an average of 5. We asked C&P what this would cost, and got a bid that seems just too high: Monthly charges: o Switched Redirect Service 20 Type 2 service@6.25 ea 125.00 20 redirecting #'s @.40ea 4.00 20 flat usage type 2@18.00ea 360.00 ------ 489.00 or o Remote Call Forwarding 20 RCF @ 16.80 336.00 Plus 9.3cents/call forwarded. This seems like a lot of money for a relatively simple switching service, within a local (no-charge) calling area. Does anyone know if there are other services that can work in this case? Other vendors? Do we really need to buy 20 paths to support 20 simultaneous calls, or is this just marketing hype?

Earthquake By Tom Steinert-Threlkeld, The Dallas Morning News Knight-Ridder/Tribune Business News DALLAS--Jan. 18 Roads of mere concrete went down in rubble, but Southern California's section of the information superhighway mostly survived Monday's earthquake. People whose telephones were useless for long-distance voice calls were able to get the word out using Internet, Prodigy, America Online and other computer-linked systems. "This is the only link I have to civilization right now," messaged an America Online subscriber, identified on the network as SoCal27822, Monday afternoon. The long-range computer link-ups survived because they work differently than standard phone systems, said Carol Wallace, a spokeswoman for Prodigy. Most local phone service in the Los Angeles area was unaffected or quickly restored after the quake. But long-distance connections were blocked by a flood of calls and Pacific Bell's decision to hold lines open for emergency use only. The Prodigy switching stations in Los Angeles and the rest of the country are connected by different lines, Ms. Wallace said. Other subscription services circumvented the long-distance logjam the same way, like an express lane on the information highway. But not every electronic on- and off-ramp was open Monday, said Rusty Williams, general manager for Delphi, another on- line subscriber service. "There are places of the information highway that fall apart in an earthquake as well," he said. "There are schools out there that are down, that aren't on the network." But those failures didn't close down the rest of the network. People across the country exchanged news, rumors, offers of help and expressions of sympathy as the horrific pictures flashed on TV screens. Some of the messages were complaints. "The telephone company needs to get on the information highway and create an on-line emergency line for local callers to get out," said Craig D8478, participating in a live "newsroom" discussion that the 500,000 subscribers to the America Online service could join. The Prodigy service, a one million-subscriber joint venture of International Business Machines Corp. and Sears, Roebuck and Co., established a special bulletin board for people who wanted to talk about the quake. More than 4,000 messages hit the board in the first six hours. A special board for Tonight Show host Jay Leno attracted 4,000 calls last year, but that took two weeks, Ms. Wallace said. Monday's bulletin board served as a clearinghouse for questions about damage in Petaluma or possible connections to recent quakes in Pennsylvania. A Dallas subscriber identified as Marva Lanier, for instance, offered to make phone calls to Dallas and Fort Worth residents, if any California callers affected by the quake could get through to her box number by electronic mail. Such relay services sprung up in almost all parts of the country, ranging from Olympia, Wash., to Mobile, Ala. The relays even took to the air, with some subscribers to the land-line services taking messages to their ham radios and broadcasting information for worried relatives. With television showing pictures of flames and destruction, some California locals used the Prodigy bulletin board as a means of calming general fears. "I can assure you that even though it seems on TV that we have been flattened, there is relatively little damage to homes," messaged a Prodigy subscriber identified as James Morrissey of Anaheim. He was participating in an on-line discussion about damage in the Northridge area, at the quake's epicenter. "Our homes are designed to withstand an earthquake many times this severe," he wrote. "This evening you will be able to phone." The informal reporting of events had its hazards. Accounts of outages of electricity, gas or phone service frequently were secondhand. Most often, the accounts traced back to a similarly "unconfirmed" news account. In one exchange, a "concerned Ohioan" said he heard that 24 people had died. At the time, a headline in the regular news section of the Prodigy service said five people were confirmed dead. Yet the story itself said 10 were dead and noted that the Red Cross was denying a report that it had told NBC News that the toll was 25. But the lack of professionalism was a relief to some who had spent the day glued to TV screens or enduring the repeated aftershocks. A Burbank man known on America Online as Noisehead was among those who took to the network for comfort and perspective. "It is nice at this point," Martin Brumbach messaged, "to get some info not delivered by anchor people."

QUAKE Sprint's all-digital, fiber-optic network withstood the early morning earthquake yesterday in the Los Angeles area with no serious damage. Generator power was required at about a dozen regenerator and point-of-presence sites along the Sprint network, but this did not affect service to customers. Sprint's four switches in the L.A. area were not affected. Working closely with local exchange carriers (LECs), employees in Sprint's Network Operations Control Center (NOCC) have so far blocked about three-quarters of a million calls going into the L.A. area. Sprint will adjust the call volumes going into the area during the next few days to accommodate the requests of the LECs, which are assessing the damage to their facilities. "Blocking the calls that go into a disaster area does two things," said Jerry Usry, director, Network Management. "First, it takes the pressure off the LEC's network so that more people in the area can call out to relatives and other loved ones. Secondly, it keeps the phone networks from malfunctioning due to call volume overload." AT&T operators are giving out Sprint's access number, 10333, to callers who are not able to get through on the AT&T network, according to Usry. "In some previous disasters, AT&T operators didn't provide callers with the codes of alternate carriers to try to get their calls through," Usry said. "As a result, AT&T received some negative criticism. During the aftermath of yesterday's earthquake, they are providing alternate access codes to callers who can't get through." Other situations that affected or posed a threat to ancillary portions of Sprint's network included: o Two central data offices of the SprintNet network were without power until generators were brought to the area. Few customers were affected by the outage because of the Martin Luther King Jr. holiday and instructions for L.A. residents to stay at home. o A switch for LD/USA, Sprint's long distance carrier in the Hawaiian Islands that also manages the company's initiatives in the hospitality marketplace, lost power until a generator could arrive. o A train derailment between Van Nuys and Camarillo spilled a toxic substance, sulfuric acid, on the ground above a Sprint fiber cable. A Sprint fiber technician is on-site during clean-up, and it appears the cable, which is encased in conduit and concrete, will be safe. "Sprint's network survived exceptionally well because of the safeguards throughout the network," Usry said. "Also, the teamwork among the Regional Control Centers, the Network field personnel and the NOCC was superb." ------------------------------ Date: Mon, 24 Jan 1994 11:12:14 PST From: Les Reeves Subject: Sprint ATM Announcement Contacts: Evette Fulton, (O) 202-828-7411; (H) 301-230-0978 Norman Black, (O) 404-859-6096; (H) 404-578-0679 SPRINT ENHANCES ATM SERVICE WITH LOW-SPEED ACCESS AND INTERNETWORKING OPTIONS -- Provides Smooth Transition to Broadband Networking -- WASHINGTON, Jan. 17, 1994 -- Sprint today announced a comprehensive package of enhancements to its Asynchronous Transfer Mode service aimed at simplifying and expanding customer access and furthering its position as the leading data networking solutions provider. ATM, a leading-edge broadband technology, is one of the key building blocks of the information highway. Sprint was the first long distance carrier to announce ATM service, in the third quarter 1993, and began offering service to its first customer in the fourth quarter. "With this announcement, Sprint is committing to provide more access options to our ATM network than any of our competitors," said Dom DeAngelo, vice president of Data Product Management. "This means customers can choose the access method that makes the most sense on a location-by-location basis." The enhancements include cost-effective lower-speed access to Sprint's ATM service and options to interwork with Sprint's frame relay service and its SprintLink(R) service, which provides access to the Internet. The enhancements also allow easy customer migration to ATM via lower-cost frame relay and T-1 (1.5 megabit per second) services at lower-volume traffic sites. The SprintLink to ATM Service Gateway will be available in the third quarter. The following enhancements will be available in the fourth quarter 1994: o T-1 ATM -- Provides cost-efficient ATM access for relatively low-volume (1.5 Mbps) users. It enables businesses to build Local Area- and Wide Area Networks on a common ATM networking platform, and allows efficient integration of data, video and voice on one transmission facility. o T-1 Circuit Emulation -- Allows customers with T-1 networking equipment to access Sprint's ATM service without any additional equipment purchases or upgrades. Using a traditional T-1 circuit, locations with existing T-1 private line equipment can internetwork with other locations that have converted to T-3 (45 Mbps) ATM access. This option, unique to Sprint, greatly benefits customers who want to protect their investment in private line applications and equipment. Customers requiring ATM's advanced capabilities for new applications can continue to operate their existing T-1 private line networks on ATM, migrating their existing applications to end-to-end ATM as slowly or as quickly as they want. o SprintLink to Sprint ATM Service Gateway -- Provides interworking between ATM and SprintLink services as an option of Sprint's commercial ATM service offering. This gateway, unique to Sprint, allows users of Sprint's ATM service to access Internet -- a group of 12,000 interconnected data networks in more than 80 countries serving government, academic and research organizations -- and will be available in the third quarter. o Multiple T-1 (NxT-1) Access -- Allows access to Sprint's ATM service via one to eight T-1 connections, providing a cost- effective alternative for customers with bandwidth requirements between T-1 and T-3 (between 1.5 and 45 Mbps). o Sprint Frame Relay to ATM Service Gateway -- Provides interworking between ATM and frame relay services on the same customized virtual network. Customers can invest in frame relay now and can easily migrate later to ATM as needed on a site-by-site basis, while maintaining full connectivity throughout their network. "Sprint's clear broadband strategy, which we announced a year and a half ago at the Telecommunications Association trade show and which includes cost-effective and easy migration paths from existing to future networks, is continuing to be critical to our customers," said DeAngelo. "These offerings are part of this comprehensive broadband strategy, which ties traditional technology to the most advanced networking solutions available." To provide many of these enhancements, Sprint will use the Wide-Area ATM Gateway multiplexer switch from Digital Link Corporation of Sunnyvale, Calif. The Gateway provides low-speed access and internetworking options by efficient multiplexing of T-1 cell, frame and isochronous (circuit emulation) traffic as well as T-3 cell traffic onto high capacity T-3 and Sonet Optical Carrier level-3 and OC-12 circuits. It is designed for central office, point-of-presence, and campus environments. Sprint also will continue to provide customers with Digital Link's premises equipment, such as the 3202 ATM DSU and the new Premisway ATM multiplexer. "Pricing is obviously important to our customers so Sprint is incorporating these new access options into its current ATM pricing structure," DeAngelo said. "T-1 ATM and T-1 circuit emulation will be priced slightly higher than Sprint's Frame Relay T-1 service, while the Frame Relay and SprintLink gateway services will have a fixed monthly fee." Sprint also will be evaluating the Alcatel Data Networks 1100(TM) HSS(TM) ATM switch for access and interworking functions. The switch will be tested at Sprint's Burlingame, Calif., Advanced Technology Laboratories. Alcatel Data Networks is a joint venture of Alcatel and Sprint. Sprint's ATM service currently is available nationwide from more than 300 locations and supports both bursty data traffic and continuous steady traffic, such as voice and video. The service offers flexible pricing, with both usage-sensitive and flat-rate billing options. Hughes Aircraft, Minnesota Supercomputer Center, Inc. and the National Information Infrastructure Testbed (NIIT) are currently using Sprint's ATM Service. Sprint is a diversified international telecommunications company with more than $10 billion in annual revenues and the United States' only nationwide all-digital, fiber-optic network. Its divisions provide global long distance voice, data and video products and services, local telephone services to more than 6 million subscriber lines in 19 states, and cellular operations that serve 42 metropolitan markets and more than 50 rural service areas. ------------------------------ From: clifto@indep1.uucp (Cliff Sharp) Date: Mon, Jan 24 1994 11:13:44 CST Subject: Modems to Merlins A friend is part owner of a small business using a Merlin Plus system. He wants to add a modem to his coterie of computer equipment (and I've been trying to get him to do it for the longest time!). However, for some reason he feels that a dedicated line is too expensive and wants to hook it into his Merlin system. Now, a little research turned up a general-purpose adapter that AT&T sells for just such use; it plugs into one of the telephones and provides a POTS look-alike that somehow can use any line. Problems with this setup (read "questions for the group"): 1. The primary reason I want the modem there is so that I can call their machine and use some sort of remote-access software to figure out what they're doing to their poor machine when they break it. The Merlin "solution" sounds to me as though I would never be able to get to their modem (or that the modem would answer any call that came in, not just mine). Yes? No? 2. For some incredibly silly reason I can't talk them out of, they demand that the first line(s) of their hunt group remain open at all times possible and unused by outbound calls. (Explaining hunting to them is very like teaching the proverbial pig to sing.) From what I understand, the adapter either seizes the first open line or has to be manually routed. How does it really work? 3. This whole thing sounds as though they're going to have to plug the adapter into a phone and route RJ-11 cable all over the office. Friend likes the idea now, but he's gonna change his mind when he sees it. Is there any other way to do it so we can run 4-pair to the modem location? ANY ideas are welcome, including how to explain to a wall that a dedicated line is his best solution.

Date: Wed, 26 Jan 1994 16:54:46 GMT U.S. ROBOTICS ADDS X.25 TO TOTAL CONTROL INTERNETWORKING PRODUCTS SKOKIE, Ill., -- January 24, 1994 -- U.S. Robotics, Inc., today announced the addition of a full-featured X.25 PAD to its line of Total Control internetworking products. The Total Control Integral X.25 PAD allows asynchronous dial-up to X.25 packet- switched networks without cabling individual modems to an external PAD. The X.25 PAD will be available in March, 1994. Total Control products support multiple protocols and interfaces, integrating complete LAN/WAN connectivity in a single chassis. The X.25 PAD may be added to the Total Control Enterprise Network Hub and Transaction Processing Hub, eliminating external equipment and RS-232 cables to increase performance and reduce per-channel cost. "X.25 allows organizations to optimize their investment in their networks," said Jonathan Zakin, U.S. Robotics executive vice president. "X.25 networks can provide cost advantages over circuit-switched networks, and can also provide an ideal solution for transaction processing applications, where short bursts of data must be transmitted quickly without error." The X.25 protocol is widely used in a variety of applications, including inquiries to corporate databases from remote sites, insurance claims processing, electronic mail, and point-of-sale transaction processing. "X.25 is the standard transmission protocol for the Ameritech Packet Switched Network, and is positioned to be the backbone for data transmission throughout the region," said Bill Fitzpatrick, applications manager for Ameritech. "X.25 is data efficient and customer-friendly, making it easy for the customer to connect to the Ameritech network." The X.25 PAD consists of an Application Card and a dual V.35/RS-232 Interface Card. The Application Card is available in 24- or 60- channel versions. The Interface Card supports two high-speed, software-configurable V.35 or RS-232 ports to connect the PAD to an X.25 network, and supports speeds up to 2.048 Mbps in V.35 mode and 57.6 Kbps in RS-232 mode. Additionally, the product supports several features that dramatically increase the number of calls it can handle. Automatic call routing reduces call setup time by automatically routing incoming calls to their destination via ANI (Automatic Number Identification), DNIS (Dialed Number Identification Service) or subscriber ID. Automatic channel configuration allows dynamic configuration of all asynchronous channels based on ANI, DNIS or subscriber ID. The product will also support protocol spoofing (VISA 1, VISA 2 and T3POS) to reduce transaction processing times. Like other Total Control Gateway Cards, such as Ethernet, Token Ring and Frame Relay, the X.25 PAD is user-programmable through an API (Applications Programming Interface), which allows users to easily customize the product to handle a wide variety of application-specific features and protocols. The Enterprise Network Hub enables organizations with remote locations, telecommuters and mobile employees to aggregate their dial traffic onto T-1 lines and route it through a packet-switched network to their host computer at a central site. The Transaction Processing Hub reduces verification times for credit card, point-of-sale, and inquiry/response transaction processing applications by interfacing with local exchange carrier services, such as Feature Group B and D. The Enterprise Network Hub and Transaction Processing Hub are logical extensions of the company's Total Control product line; U.S. Robotics' Total Control line of intelligent modem management systems, introduced in 1990, was the company's first entry into this market. Both products use a common architecture, which consists of a 1 Gbps midplane, and circuit and packet-switched buses to minimize processing time. Through downloadable software- defined technology, U.S. Robotics can easily modify and enhance its products to take advantage of new and emerging technologies. U.S. Robotics, Inc., (NASDAQ:USRX), is a leading designer, manufacturer and marketer of data communications systems and products. Both corporate headquarters and manufacturing operations are based in Skokie, Illinois. U.S. Robotics owns and operates U.S. Robotics Ltd. in Slough, England, U.S. Robotics, s.a. in Lille, France and P.N.B. s.a., based in Suresnes, France.

Date: Wed, 26 Jan 94 06:03:46 GMT Washington Post, 1/24/94 Getting Connected Gets Costlier As D.C. Pay-Phone Rate Rises By Ruben Castaneda Washington Post Staff Writer It costs 5 cents more to make a pay phone call in the District, but that didn't make a nickel's worth of difference yesterday to several Washington residents. Some, like Anna Toyos, who used a pay phone at Third Street and Massachusetts Avenue NE yesterday to tell her family she was on her way home from work, didn't even realize the increase -- to a quarter -- had taken effect. "I didn't notice that it was 20 cents before," Toyos said. "I don't use them that often. Maybe that's why I didn't notice." Last month, the District government authorized Chesapeake & Potomac Telephone Co. to increase its revenue by $15.8 million by increasing rates this month on business customers, on special services such as call waiting and on pay phone calls. Basic residential rates were not affected by the increases, which were determined by the city's Public Service Commission. C&P [now officially Bell Atlantic - the ads have been airing this week - Mike] had been requesting increased revenue of $35.1 million, and company officials said they would appeal the commission's decision. A consumer advocate also criticized the rate increase, but for the opposite reason, saying it would be costly for phone users. But people using pay phones yesterday didn't mind -- at least not too much. "I think it's fair," said Charles Hackley as he stood near a pay phone that his wife, Pamela, was using on the edge of downtown. Hackley noted that pay phone calls in Northern Virginia and suburban Maryland already cost 25 cents. "I think people in the District have been lucky," Hackley said. "Stamps have gone up. It's about time phone calls went up. "I do think they should use the increase to fix a lot of the phones that don't work," he added. Pamela Hackley said she didn't like that rate increase but didn't want the pay phone she had just used to be repaired. "When you make a phone call on it, more money comes back when you finish the call," she said, displaying a handful of quarters. "I was her lookout," her husband joked. [End of article] It's funny, I only recently was reading an article saying how they should once and for all raise the pay phone rates to a quarter. It was mentioned how most people don't bother to get the exact change and plop in a quarter anyway.

Many of you have joined me in ACS activities over the Internet network. I ask members to put that experience to work for the benefit of the Australian community. Help connect your neighbours, your community group, your school, company or government department. In June last year the ACS wrote to the Prime Minister of Australia, urging the Government to join our American friends on the electronic frontier. The Department of Prime Minister and Cabinet is now considering this issue, in it's latest IT Strategic Plan. During 1994 the ACS will contribute its expertise to create a national system linking IT professionals. They will be encouraged to transfer this knowledge to their clients, companies and government agencies. The ACS Canberra Branch established a pilot system in 1993 to provide limited network service free, to members. From 1 March 1994 ACS Canberra will provide a full Internet service for a small fee. IT professionals will be asked to showcase Australian products and services, using the global data networks. Members will be encouraged to also use the network to support local cultural and community groups. Almost one hundred years ago Australia's founders created a new nation. It was formed from a common heritage and in part, united by the communications technology of its day. As we approach the year 2001 a new technology is emerging from Australia's universities and research laborites. Just as the telegraph made it possible for Australians in 1901 to receive news across the content, "data highways" will allow all Australians to communicate across the world. As trailblazers on the new electronic frontier, let us dedicate this task to Australia's early pioneers. The goal is that all Australians will have access to the public data network, by the dawn of the new millennia at the centenary of Australia's federation. Tom Worthington , Director of the Community Affairs Board Australian Computer Society Inc. Fax: +61 6 2496419 23 January 1994 ABOUT THE ACS: The Australian Computer Society is the professional association in Australia for those in the computing and information technology fields.

The idea is the very same as that used by Telepassport (for whom I am an independent representative). Calls from other countries to the USA are 're-originated' here at a savings in cost to the calling party. Of course, I would *prefer* that if you make a lot of international calls to/from the USA and other countries that you use Telepassport, since your support and use of the service helps the Digest, but none the less, the message which follows will inform you of another such program available. For information on Telepassport, write me and ask for the file; for more information on the service below, write those people instead. PAT] Newsgroups: misc.consumers From: mavihoja@cscns.com (Michael D. Beatty) Subject: International Dialback L.D. Organization: Community_News_Service Date: Sat, 22 Jan 1994 14:04:34 GMT To Fellow Internet Users: I will do my best to describe my need in as concise a manner as I can. I am the marketing Vice President for a relatively new company in the field of telecommunications, namely, the call re-origination phenomena. Some refer to this technology as "dialback", the terminology isn't of any great importance. The technique is as follows. The customer is given an access number in the U.S. in order for him to partake in U.S. system benefits and rates. He calls this number, hangs up after two rings, then the computer, "Fred", calls him back and says, "This is (company name), you are ready to dial." This process saves in percentages that attract callers all over the world, and quite frankly, the business is coming in at rates that are a little cumbersome. The problem, as I see it is that if a firm marketing structure and discipline isn't set down at this healthy juncture, we will pay the price in the future. You can undoubtedly see how this kind of thing could attract the type of individual who always wants to go for the "big deal" before he sets up his primary income stream ... based on regular users. We have had so many requests for one company or individual to apply for exclusive rights for an entire country, that it is really starting to rub me the wrong way. My request is this... Keeping in mind that the competition is quite sparse, meaning that according to our research there are only 3-5 others doing this type of business in any level of effeciency or size, and considering that we have a responsible interest in adhering to a marketing structure that will avoid inherent pitfalls of "network marketing", I would at this time like enlist your input, guidance, ideas, etc. We began the outreach worldwide with the intention of building a "tree" approach, i.e., The agent who signs up a user gets .08/min on any users HE signs up, .04/min on any of his agents users in his immediate downline, .02 in the next, .01, then finally on the 5th level, .01. In all honestly, we don't know if this is the most effecient method to market this product. Let's take an example. I personally got a call from a gentleman in Nigeria, who discovered that by using our service, he could avoid paying the local PTT in Nigeria the $5.00 per minute charge to call the U.S. and instead be charged our rate of $1.35/minute. He immediately expressed an interest in spreading the word about our product around his country. Many folks who are in the similar position ask for exclusivity right up front, and want 10-12% commission. So far, we have the latitude to pretty much cut any "deal" that is requested, or required, but sooner or later the cookie cutter approach is going to become necessary if we are to adhere to consistancy. My levity is to get away from the "shoot from the hip" approach, and formalize the alternatives into a formula for utilization of energies and distributing the opportunities available as fairly as possible. If you need anymore specific explanation of how the actual product works, I will be glad to do that, but at this time I'd like to open the thing up for scrutiny ... what is the most expedient methodology to market such a beast? Discussion would be more than appreciated. And, just for your informational purposes, the following is a file that we use to explain our services to potentially interested parties. The rate of expansion that we are experiencing is explosive and exponential, due to the fact that that system actually DOES save the customer the amounts promised. COMMUNICATIONS SYSTEMS INTERNATIONAL, INC. Substancially reduce cost of calls from almost ALL Countries to U.S. and other destinations ... CSInt'l is a revolutionary way to place INTERNATIONAL LONG DISTANCE PHONE CALLS AT SUBSTANTIALLY REDUCED RATES (30 to 70%)!! By routing all your international calls through the United States, we place the LOWER RATES and COVERAGE of the U.S. phone system right in your hand. And since all your calls are handled by our state-of-the- art computer, all of its special features and advanced abilities are also at your disposal. With CSInt'l you can call FROM any of the 235 countries in the world TO any of those same countries - virtually the entire world. You can start using CSI today WITHOUT CHANGING YOUR PHONE EQUIPMENT OR SERVICE HOOK-UP IN ANY WAY. All you do to use the CSInt'l computer is simply call it. There are no calling cards to get lost or stolen, no billing account digits to enter, In fact, you can place an international call with as few as four digits! All calls are completely automatic - no operator assistance is required. You are billed in 6 second increments instead of whole minutes. BENEFITS % Simple to Use. % No Risk. % Speed Dialing. % No Equipment Modifications Needed. % Keep the Line for as Many Calls as you Need. % Faster, Fully Automatic Dialing. % Eliminate Hotel Surcharges. % 6-second Billing Increments. % Crystal Clear High Quality Digital Transmission. % 48 Hour Activation. % And of course -- LOWER RATES. HOW IT WORKS We assign you a special unlisted U.S. phone number that you will call and then hang up after 1-2 rings. Since you hang up (and we don't answer) there is no charge for the call; however, our computer knows you called and WILL CALL YOU BACK. At this point you simply answer the phone and dial the number you wish to call. That's all there is to it. The CSI phone program does NOT have multiple levels of menus or or long instructions to listen to. All of its functions are accessed from a single familiar place. Nothing could be easier to use in making long distance calls. When you finish talking you can either hang up like you normally do, OR you can press the star key twice (**). The ** hangs up the other end of the call, but keeps you connected to the CSInt'l computer so that you can place another call. You can use the ** as many times as you like. In fact, we deduct another 5% off the per minute rate for all calls you make using this feature. The ** feature is also handy for hanging up on answering machines or voice computers that you don't want to pay to talk to. TOUCH TONE You DO NOT have to live in a touch-tone dialing country to use CSInt'l. However, your phone must be able to produce touch-tones in order for you to use CSInt'l. If you have any question regarding this, we give you a hand held tone dialer that does the tone dialing automatically for you. Most phones have a tone/pulse switch that you simply flip to the tone position when you answer the dialback call. The sooner you get started the sooner you'll begin saving ... Our pricing is the most thorough in the industry. We break the world up into as many areas as possible to bring the best possible rates. WE HAVE A PRICE THAT YOU WILL KNOW IN ADVANCE FOR EVERY POSSIBLE COUNTRY TO COUNTRY CALL. Instead of sending you 600 pages of pricing though, we have all of those prices in an IBM-PC compatible program that you can use to look up any call price in seconds! This program compares all countries prices with all other possible combinations of calling destinations. BILLING Our billing is just like what you are used to. You use the service and we send you a bill. The only thing we ask is that you place an approved credit card on account with us. We accept all standard forms of payments, including all major credit cards. If a credit card isn't available, then we require a $250.00 Security Deposit (to be held in a government insured account) .

A couple observations are in order: the two differences between Telepassport (my offering) and the above are the method of billing and their emphasis on MLM (multi-level-marketing) to promote the service. Telepassport does not require an advance deposit. We offer credit card billing or electronic funds transfer with a debit to the checking account of the subscriber. We have no method of or desire for taking cash in advance. We do not do MLM. Every representative is an independent person accountable only to the parent company, US Fibercom. Our rates are quite comparable to the above service I suppose, however we charge a monthly minimum use fee of $25. Use it or lose it. We do not for that reason encourage subscriptions to the service from people whose international long distance is less than $25-30 per month. I do receive a residual from the use of Telepassport by subscribers who have signed up through me and the money thus received is used to help offset the expenses involved in the production of this Digest. Indeed, 'call re-origination' or international dialback as it is sometimes known is a growing industry, and persons in countries outside the USA are finding out that our international rates here are much better than their own. They can re-originate, we can mark up the costs to make a profit for ourselves, and they still wind up paying less than through their own telecom administration. Ask for more details if desired.

I suggested maybe the old threads could be closed out. One reader, Jack Decker was furious to hear this. He was, and apparently remains convinced that all these events were merely a ploy on my part to censor and silence his difference of opinion regarding 'unmeasured local service.' Even though Jack was given space for two large articles on the topic including one to specifically rebut what I said, and even though one issue of the Digest was devoted entirely to replies, most of which rebutted what I had said, Jack feels this was not enough and that I deliberatly cut off the topic before he could say his piece for yet a third time. He wrote a nasty flame article to c.d.t.t. (where flames about you-know-who are always received graciously) telling how he was censored. He does not like having his work edited, and he said to me he thinks I should publish 'everything anyone writes to me' with no comments. He wants to see it all ... so for the next 12,000 bytes more or less, I present Jack Decker's unedited (and third) article on why he opposes measured local service. Then following, in the same amount of space *or less*, a few more sentiments on local measured service. Jack has stated in the future he won't be writing to me and that he intends to send his stuff to c.d.t.t. where obviously -- since it is a Usenet newsgroup -- anything goes, and usually does. Sounds okay to me. :) I will respond to only one of his remarks; see the end of his message. PAT] ------------------- Pat, I will agree with the sentiment that has been expressed by others here. I fail to understand why you defend the idea of mandatory measured service when in fact it has cost not only you, but many other Chicagoians much additional expense. With your indulgance, I would like to respond to a couple of things you said, but also add another dimension to this discussion. That dimension is this: As a matter of public policy, do we want to encourage or discourage people from communicating with each other? There is a saying (especially popular among those of a conservative political bent) that when you want to discourage an activity, you tax it. If, for example, you don't like privately-owned business, then you tax privately-owned businesses heavily. If you don't want people to smoke or drink, you put high taxes on those activities. Now a tax is really a fee based on some activity, imposed by the government. Whenever you take some activity that was formerly free, and then put a fee or tax on that activity, the number of people who engage in that activity will drop. For example, fewer people (as a percentage of the total population) engage in fishing and hunting when those activities are taxed. By the same logic, if we impose usage-based fees on telephone calls, a certain number of people will decide not to make a certain number of calls. And in at least some cases, those will be calls that should have been made, or that would have been of benefit to someone, maybe even to you. (As a side note, most billing in the United States pretty much assumes that the beneficiary of a call is the caller, therefore the caller pays for the call. But in some cases the primary beneficiary of a call is the called party. That raises a whole separate set of issues that I won't go into now). My question is whether we really want to discourage phone calls. The only possible benefit that I can see from discouraging calls is that the phone companies can get by with installing slightly smaller switches. I say "slightly" because as you know, peak usage occurs during the business day and most business calls are already measured and would be made anyway. So while the total call volume may decrease, I think the actual peak calling volume would drop very little, and telephone company switches have to be engineered to handle peak calling volume. I also suspect there's not a great cost difference in over-engineering a switch, when you amortize the switch cost over its lifetime and the number of customers served. On the other hand, if we discourage local calling, it could have some negative side effects, such as causing people to become more isolated from one another. Pat, you've often bemoaned the condition of some neighborhoods in Chicago; maybe part of the reason that some people there are acting with less regard for human life is that they aren't getting the daily calls from grandma or their parents or siblings anymore. Sometimes lonely people tend to strike out. I'm certainly not saying this is responsible for all the crime in Chicago, but if you could avert even 1% of the criminal activity by making it easier (that is, less expensive) for people to communicate with each other, would you do it? When you think about it, people have become pretty isolated from each other. We don't sit on front porches and talk to passers-by anymore (you might get shot doing that!); instead we hide behind our walls at home and watch TV, which is a one-way medium (and I'll avoid a diatribe about program content for the moment). TV comes into our homes for free (if we use antennas) or at least on a mostly usage-insensitive basis (yes, I know that pay-per-view exists, but few people spend much time watching it). Now we have this other technology that lets us reach out and talk to others, including friends and loved ones, and THAT we are starting to charge for. The technology that tends to tear us apart is free, the technology that brings us together is "taxed" (in the broad sense of that word; I realize it's not really "taxes" but it's the same effect. Even the government is calling new taxes "user fees", so they can tell folks they didn't raise taxes!). Then there are also the environmental concerns. Put simply, if calls are free, you are more like to call "just to make sure" that someone is home, or that a business is open. I can remember times that I "knew" that a certain business was still open, but decided to call anyway "just to make sure". Had I had to pay for the call, I would probably just have driven over there (and been unpleasantly surprised to find that I "knew" wrong). My point is that it is much better for the environment to make a phone call than to drive someplace on a wild goose chase, and again, usage based charges discourage this. (I want to interject here that I KNOW there are people in the world who don't care what a call costs; they just call whomever they want and worry about the bill when it comes. But there are also a lot of people who will in fact decide NOT to make a call if it costs money. Neither group is going to convince the other to change its ways!) In my opinion, we should encourage people (especially residential customers) to use the telephone, rather than discourage it. We do that by providing service in a way that does not penalize usage. If that means that telco has to spend a few extra bucks on switches that have adequate capacity, let them amortize that in the monthly phone bills over the life of the switch (I'll bet it would amount to over ten cents per month per customer, probably a LOT less). Besides, you might really wish you had that extra capacity during the next emergency in your area. Now a couple quick comments on what you said: [Comments on temperature in the Windy City deleted...] > ..... None the less, it warms my heart to read > messages from you guys singling out telco as the one utility service > which you feel should be an exception to the 'pay for what you use' rule. > > Would you like to pay for your electrical service based on some average > amount that all your neighbors, including the big factory across town > uses?

Betcha the owner of the laundry would consider it to be 'fair'. Pat, you say this but then later you acknowledge the crux of the argument, but then go on to do what in my opinion is some really wild speculation: > Jack contends that the use of the > phone does not affect telco's costs, and while that is partly true > (and more true than it is in the case of the gas, electric or water > utilities, all of whom have to obtain and pay for (or 'manufacture' in > the case of electricity) the product they are passing along), it is > not entirely true since the size and extent of the *common equipment* > telco must install and maintain DOES depend on the extent to which it > is used.

Ditto with telco. Pat, where on earth did you get the idea that "a telco has the physical capacity to serve only about ten to fifteen percent of its customers at any one time"? Even if that were true, and I seriously doubt it is, it would be true only of the central office switch, and that is only a small part of telco's total costs. With very few exceptions, the wires, cables, and other physical plant dedicated to bringing phone service to your home are reserved for your use 24 hours a day, for as long as you have phone service, whether you ever place a call on it or not. Telco doesn't assign my wire pair to someone else when I'm not using my line, the way Hertz assigns cars. As for the switch itself, I would again point out that it has to be engineered to meet peak calling demand, and that generally happens during the business day when relatively few residential customers are using their phones, and in many places business customers are already forced to have measured service. You compare telephone service to electric or gas service. The only thing that telephone service has in common with these is that it is provided by a regulated utility. But with gas or electric service, it costs the utility more money to produce more of the product. Electricity or gas is essentially a product (a certain amount of energy is delivered), while telephone is a SERVICE. Pricing them differently is therefore appropriate, especially given that the telephone company's costs are either not increased at all, or only a very minute amount when people make more calls. I suggest that a more appropriate comparison might be that of renting an appliance, such as a refrigerator. When you have phone service, you are essentially renting the use of the phone lines (and other outside plant) and the central office switch. In both cases the equipment may wear out over time, but not with any particular correlation to usage. When you rent a refrigerator, the rental company could put a unit counter on the door, and charge you a few cents every time you opened the door. That would be the equivalent of measured telephone service. But in a free market where more reasonable rental plans are available, no one would rent a refrigerator under those terms. And the fact is that rental companies are free to rent refrigerators this way, but they do not. One other quick point: You said: > Jack Decker agrees with me that frequently (but only 'at first' in his > opinion) the costs to many subscribers are lower, and on this point he > apparently would be in disagreement with Bill Pfieffer and Cliff Sharp > who feel the bills always are more. Actually, I was going by what you had said, simply accepting that particular statement at face value so that we could get on with the discussion. Since it appears that some of your fellow Chicagoians disagree with you on this point, perhaps I was a bit hasty in "agreeing" that the costs to many subscribers are lower. Revise it to read that the costs to SOME (perhaps relatively few) subscribers are lower... and I still stand by the statement that this is only at first, until telco feels that they can get away with raising the rates. By the way, you thought it was cold in Chicago... about the time you were feeling distressed at the cold, it got down to 29 below zero (Farenheit) in Sault Ste. Marie, Michigan (the HIGH for that day was -12!). We had it warmer here, I think it only got down to about -4 here (near Muskegon). I think I am glad I no longer live in the frozen tundra! :-) Jack [TELECOM Digest Editor's Note: There you go Jack. More or less the last word on the topic, unedited, raw, just like you sent it. I had to dig around in my bit bucket to find it. One response: telcos have the physical capacity to serve at most 10-15 percent of their customers at one time. They plan their capacity based on their 'busy hour'. Maybe someone will be so kind as to write to Jack and explain how the common equipment in a CO is arranged. Five million subscribers in Chicago do not have five million dialtones and five million possible connections *all at one time*. Will someone please explain that to Jack? Thank you.

That's the technical approach: pass through the cost actually caused by the customer. Telcos are service providers. An approach probably often found with European telcos (certainly here in Germany) is to charge a fee for every service, the more useful the service is the more expensive it gets, with no regard to the actual cost (except that there should be a net profit altogether). >> Hahahaha hahaha ha ha ... he ho hummmm ...

Cantor Local telephone charges are regulated because (at least until very recently) the local telco has a natural monopoly. It would be interesting to determine what charges might be if there were real competition. Say, three or four companies each capable of providing local service and with a minimal real cost (to the telco) of switching a customer to that telco. In truly competitive situations, rates tend to more closely reflect real costs, with the exceptions that those customers who have the least choice get charged the most. A good example of this is airline ticket charging on competitive routes or grocery store pricing. In a truly copetitive situation, what would the telcos' strategies be for charging? how much would they charge for switching? Would they meter local charges? Would there be telephone discount coupons, modem coupons, earthquake spcials? One might even argue that the regulated rates of today should be based on what truly competitive rates should be.

Can NT1's be line powered? I am unaware of any "line powering" of ISDN CPE in the USA. Perhaps what is meant by "line powering" of the AT&T 7506 is that the NT-1 and associated power supply is located in a telephone equipment closet somewhere at a customer location and that is the power supply for the 7506. As to NT1s, the same applies. In the USA, there is no power provided via the ISDN line to power either the NT1 or any CPE behind it. > Next, where are the RBOCs putting NT1s for normal residential ISDN > hookups?

Is this being done in practice? The NT1 is provided (in the USA) by the customer, so there is no option on the part of the telephone company. Any residential ISDN line brings the 2 wire U interface directly to the customer's residence and then the customer (or an authorized agent) installs the NT1 and all other equipment. > My reasons for asking about this are to determine whether ISDN > residential lines are "lifeline" capable in all cases.

That concept, however, is being studied to see if a combination of "load shedding" and/or a reversion to a POTS only capability may be a possibility. It is not, however, a current capability.

It's probably based on a Telecom Finland press release. Some fast facts - Finland has about 500 000 mobile phone subscribers (ARP and NMT analog nets, both GSM nets). Per capita that's the highest number in the world (95 / 1000 people), Sweden is second. USA was not listed. - 10 % new subscribers last year chose GSM, 77 % NMT-900 and 13 % NMT-450 - out of 450131 Telecom Finland subcribers about 2 % use GSM, 59 % NMT-900 and 39 % NMT-450 - 30 % of new subcribers are expected to choose GSM this year instead of NMT - 14 % of subscribers are private users, but nearly 50 % of new users aquire their mobile phone for private use. It's quite often cheaper to get a mobile phone than a normal phone. - Telecom Finland has 420 GSM base stations; they plan to increase the number to about 900 by the end of this year (since they also plan to invest 300 M FIM (about 54 M USD) mainly to their GSM net, you might assume that one GSM base station costs about 625000 FIM (112000 USD)) - short messaging -, fax - and data services should be available on GSM this year (some of them even this spring, depending on the status of GSM phase II standardisation). Unfortunately I've not seen similar press releases for Radiolinja Oy, the other GSM operator.

I use it every time I have to explain "client-server" or "distributed processing" to anyone. Because X works backwards. Most people, no matter how carefully you explain the client-server concept, get hung up on the notion that the "server' is always "the big box," "their box," or "the far away box," with the "client" being "the small box," "my box," or "the close box." This is because most examples have to do with services that involve "their" file server, a "big" compute server, or a "far away" data base server. It is extremely useful to be able to describe the user interface as a service which other computers use as clients. Here, then, is the definitive guide to programming with X, or, more formally, the "X Window System", or, more commonly but less properly, X-Windows. (I had originally assumed that this latter reference was possibly due to some confusion with the Digital specific implementation and extension, DECWindows. Digital equipment and personnel have played a large part in the birth and development of X. However, Robert Scheifler saw references to X-Windows before the DECWindows product existed, and thinks it must be due to an assumption that the naming followed the "Microsoft Windows" form.) Part of the popularity of X is the fact that there is a considerable library of routines ready made for implementing X systems. Part one of the book, therefore, starts with sixteen chapters detailing the available libraries by function. Part two then defines the formal X Window System protocol. Part three deals with inter-client communications conventions, while part four discusses fonts. There are nine appendices and a glossary. copyright Robert M.

Sprint will demonstrate SprintLink PLUS directory and security features for the first time at the Communications Networks industry trade show Jan. 25-27 at the Washington, D.C., Convention Center. SprintLink PLUS lets industry-specific applications, such as collaborative engineering and design, run over the Internet. It also simultaneously offers directory, security and other value-added services. Using the service, for example, a group of specialized engineers from companies worldwide could form a "virtual corporation" and work cooperatively over the Internet on a design for new aircraft. Through their UNIX workstations, IBM PCs with Windows(TM) 3.1, or Macintosh computers, members would connect to the engineering network through a sign-on procedure that controls the level of access based on the user's ID and password. Once on, the engineers have the capability to simultaneously gain access to public databases or component libraries, in addition to private information such as the aircraft design. SprintLink PLUS is the first product of Sprint's alliance with the information technologies development consortium Microelectronics and Computer Technology Corp. -- also known as MCC -- to develop electronic commerce applications on the Internet. SprintLink PLUS combines Sprint's public data Internet service -- SprintLink(SM) -- with MCC's Enterprise Integration Network. EINet(TM) is an advanced communications infrastructure that helps users locate the information they need and create a secure environment for conducting transactions while also providing other key value-added services. SprintLink PLUS value-added services initially will include: o Directory Services -- SprintLink PLUS Directory Services make it possible to "look up" information in an integrated data network environment as easily as flipping though a phone book. In the engineering example, component libraries could be sorted by a number of criteria, such as by manufacturer, type, speed or price. Using the content-based directory, users can retrieve information by using simple keywords, phrases or questions. The service lets users easily canvass thousands of sources of on-line information such as books, journals, magazines, financial information and library catalogues. o Security Services -- SprintLink PLUS Security Services let users safeguard proprietary directory and other information against unauthorized access. Users decide on a need-to-know basis who should be able to browse, access and retrieve the organization's information. Security Services protect against Internet security breaches through a two-step identification process: User Authentication and Access Control.

That person said the PR Department would be contacting me, but thus far I have heard nothing more; so here is the version I got from the 'underground' :) -- one of my various contacts at the company. ------------- THE FOLLOWING IS ANOTHER IN THE SERIES OF UPDATES THAT RELATE TO THE CATASTROPHIC EARTHQUAKE THAT STRUCK SOUTHERN CALIFORNIA AT 4:31AM PDT ON JANUARY 17, 1994. WE CONTINUE TO EXPERIENCE FREQUENT AFTERSHOCKS. A LITTLE AFTER 1:00 PM PDT TODAY, THE AREA WAS ROCKED BY TWO STRONG AFTERSHOCKS. STATUS AS OF 5:00PM PDT - JANUARY 19, 1994 I. EMPLOYEE ISSUES OUR EMPLOYEES ARE BEGINNING TO RETURN TO WORK IN THE BUILDINGS IMPACTED BY THE EARTHQUAKE. EMPLOYEE SAFETY REMAINS PARAMOUNT AS THEY RE-ENTER THE FACILITIES AND BEGIN WORKING. THEY HAVE BEEN SUPPLIED WITH SAFETY EQUIPMENT SUCH AS HARD HATS AND DUST PARTICLE MASKS CONSISTENT WITH GTE SAFETY PRACTICES. WE HAVE MADE ARRANGEMENTS TO OFFER BUSING FROM THE ANTELOPE VALLEY INTO SAN FERNANDO. WITH THE DAMAGE TO THE FREEWAY SYSTEMS ON THIS HEAVILY TRAVELED ROUTE, THE DRIVE IS BECOMING VERY TIME CONSUMING. THE BUS SERVICE WILL TAKE CARS OFF THE ROAD AND LESSEN THE FATIGUE ON COMMUTING RIDE THE BUSES. A TELECOMMUTING CENTER IS BEING ESTABLISHED IN A GTE BUILDING IN LANCASTER. THE SITE WILL ALLOW SOME EMPLOYEES TO WORK FROM A SITE IN THE ANTELOPE VALLEY RATHER THAN DRIVE INTO THE SAN FERNANDOR VALLEY. THIS SITE WILL HOUSE THE DATA SYSTEMS AND EMPLOYEES THAT NORMALLY WORK IN THE DAC, CARE CENTERS, OPERATOR SERVICES AND BILLING CENTERS. IT IS HOPED THIS CENTER WILL BE OPERATIONAL WITHIN THE NEXT WEEK. THE TELECOMMUTING CENTER IS A PARTNER VENTURE BETWEEN GTE, PACIFIC BELL, RAND CORPORATION, AND CITY AND COUNTY AGENCIES. PUBLIC AFFAIRS WILL BE DISTRIBUTING RELEASES TO THE MEDIA ABOUT THE VENTURE. WE ARE EXTREMELY PROUD OF THE EMPLOYEES WORKING IN THE DISASTER AREA. THEY HAVE A "CAN DO" ATTITUDE AND ARE COMMITTED TO GTE'S RESTORATION EFFORTS. 2. CUSTOMER SERVICE ISSUES A. THE MISSION HILLS CARE CENTER IS PARTIALLY OPERATIONAL. THERE ARE 50 WORKING POSITIONS STAFFED AND PROCESSING CALLS. THERE WILL BE ADDITIONAL POSITIONS ADDED ON THURSDAY THE 20TH. ADDITIONALLY, IN THE SAME BUILDING, WE HAVE SOME DAC, FAC AND MARK ACTIVITIES IN OPERATION WITH MORE RESTORATION EXPECTED TOMMORROW. THE NUMBER OF TROUBLE REPORTS CONTINUES TO BE ABOVE THE AVERAGE DAILY VOLUME. HOWEVER, THE DIVISION AND CARE CENTER PERSONNEL CONTINUE TO MEET SERVICE LEVEL OBJECTIVES IN RESPONDING TO THEM. B. TODAY'S AFTERSHOCKS CAUSED SOME ADDITIONAL DAMAGES TO THE MOST SEVERELY DAMAGED BUILDINGS. THE LAND AND BUILDINGS DEPARTMENT IS HAVING A STRUCTURAL ENGINEER REVISIT THOSE ADDRESSES TO ENSURE THE BUILDINGS REMAIN OCCUPIABLE. THE LAND AND BUILDINGS DEPARTMENT WILL BE MEETING WITH THE STRUCTURAL C. THE BUILDING SHARED BY THE CUSTOMER CONTACT CENTER AND OPERATOR SERVICES IN GRANADA HILLS HAS SUSTAINED SO MUCH DAMAGE IT WILL BE ABANDONED RATHER THAN SPEND THE CAPITAL DOLLARS TO RESTORE IT. THAT FACILITY WAS TO HAVE BEEN UNLOADED OF EMPLOYEES DURING THE SUMMER MONTH'S ANYWAY. THERE IS ABESTOS PRESENT IN THE FACILITY AS WELL. THE PROPER STEPS HAVE BEEN TAKEN FOR THE REMOVAL OF THE ASBESTOS MATERIAL BEFORE WE REMOVE THE THOSE DEPARTMENTS AND LA . A NORMAL OPERATION BY THE END OF THE WEEK. E. NETWORK SERVICES IS WORKING WITH TRAFFIC FACILITIES TO RE-EVALUATE THE CALL ROUTING. THE EARTHQUAKE AND IT'S AFTERMATH HAVE CHANGED THE CALLING PATTERNS IN THE IMPACTED AREA. AFTER THE EVALUATION IS COMPLETE, CHANGES WILL BE MADE TO ACCOMODATE THE NEW PATTERNS. F. ONLY THE GRANADA HILLS CENTRAL OFFICE REMAINS ON GENERATOR POWER. THE REMAINDER OF GTE FACILITIES HAVE BEEN RETURNED TO COMMERCIAL POWER. G. THE NATIONAL WEATHER SERVICE IS PREDICTING RAIN FOR FRIDAY AFTERNOON AND NIGHT. LAND AND BUILDINGS AND BUILDINGS FLEET AND ENERGY ARE WORKING TOGETHER TO ENSURE THE ROOFS OF ALL OF THE BUILDINGS IN THE IMPACTED AREAS ARE INSPECTED AND REPAIRED TO PREVENT WATER DAMAGE TO COMPANY FACILITIES. ADDITIONALLY, PLASTIC WILL BE ORDERED, DISTRIBUTED AND SURPLUS QUANTITIES AVAILABLE IN THE EVENT AFTERSHOCKS CAUSE LEAKAGE BETWEEN NOW AND THEN. INITIAL ASSESSMENTS HAVE REVEALED THE FOLLOWING: 1. A TRAILER PARK IN SAN FERNANDO REMAINS OUT OF SERVICE DUE TO DAMAGE TO PLANT AS A RESULT OF A FIRE DURING THE INITIAL QUAKE. THE MATERIAL TO RESTORE SERVICE WAS ON SITE ON TUESDAY THE 18TH. HOWEVER, A HAZARDOUS MATERIAL CONDITION PREVENTED CREWS FROM BEGINNING TO RESTORE SERVICE UNTIL THIS AFTERNOON. THE CONDITION HAS BEEN CLEANED UP. PLACING AND SPLICING CREWS WILL RESTORE SERVICES TOMORROW. 2. A SHOPPING CENTER WAS PROVIDED TEMPORARY SERVICE AERIALLY. THE RISER WAS INACCESSIBLE DUE TO A FIRE AFTER THE INITIAL QUAKE. 3. COMMUNITY ISSUES A. WE HAVE INSTALLED COIN TELEPHONE TRAILERS WITH FREE LOCAL AND LONG STATION, AND THE REMAINING THREE ARE IN RESIDENTIAL AREAS WITHOUT TELEPHONE SERVICE DUE TO FIRES RESULTING FROM THE INITIAL EARTHQUAKE.

AT A REGULAR MEETING OF THE CALIFORNIA PUBLIC UTILITIES COMMISSION TODAY, THE COMMISSIONERS ACKNOWLEDGED ALL UTILITIES FOR THEIR RESPONSE FOCUSING THEIR ATTENTION ON TRANSPORTATION ISSUES. EMPLOYEES. THEIR EFFORTS IN EXTERNAL COMMUNICATIONS ARE ALSO BROADBASED AND PROVIDING GTE WITH MEDIA EXPOSURE. THEY INCLUDE: MEDIA NEWS RELEASES THROUGH WIRESERVICES; FILM FOOTAGE OF DISASTER SCENES TO ENHANCE REPORTERS PRESENTATIONS OF GTE MEDIA MATERIAL; RESPONDING TO MEDIA INQUIRIES; GRANTING INTERVIEWS; PRESENTING A GTE FOUNDATION GRANT TO THE RED CROSS IN PARTNERSHIP WITH KNBC TELEVISION; AND OTHER OPPORTUNITIES TO INITIATE POSITIVE MEDIA COVERAGE. ADDITIONALLY, PUBLIC AFFAIRS IS WORKING WITH PRODUCT MARKETING TO PROVIDE LARGE TENTS AT THE PUBLIC SHELTERS IN SUFFICIENT TIME FOR THEM TO PROVIDE PROCTECTION TO DISPLACED PEOPLE WHEN THE RAINSTORM COMES ON FRIDAY. THEY ARE ALSO DONATING PLASTIC BAGS AND CARDBOARD BOXES TO DISASTER SHELTERS TO ASSIST INDIVIDUALS IN PACKING AND MOVING THEIR BELONGINGS.

PAT] Pat: At 16:22 PST, Dane Pasco (phonetic spelling) of Pac*Bell said on KCBS-AM 740 (San Francisco/Oakland/San Jose) that: . volume was causing call setup delays into and out of LA . LD traffic in and out of the basin was extremely high . no Pac*Bell customers are without service (!) . area codes 909, 818, 213, 310 are the most affected . the 611 repair-reporting center in Van Nuys suffered physical damage; thus, repair calls are being rerouted to another location. Earlier this morning (sometime around 11:00 PST), an AT&T representative (whose name I didn't catch) indicated that one of the AT&T switches in the area had suffered a loss of emergency power, and calls into and out of the area were affected. Unfortunately, I don't recall which switch it was; he, as well, was on KCBS.

Basically, my problem is this: I need to make a several-hour call daily from the 510-357 prefix (DMS100) to a 510-236 prefix (1AE). This call however is a toll call, so I setup an RCF in the 510-486 prefix (1AE) which is local to both numbers so that I can save on toll charges. During the duration of this call, I will mostly be transmitting data with my modem. If this were purly for a voice call, I would probably have never noticed a problem -- that is, I lose about 20% of my data Transfer Rate when dialing through the RCF. I would otherwise have a perfectly good connection if I dialed direct from 510-357 to 510-236. I have checked the data transfer rates from 510-486 to 510-236, and they also seem to be operating at normal rates. I have also checked the data transfer rates from 510-420 (1AE) through the RCF and they are also within normal data transfer rates. Something is clearly happening because of the RCF, but it only seems apparent when I'm dialing from this DMS-100 in 510-357. Pacific Bell recommended that I try puting in a service order for disconnection of the RCF, and then reconnection a day or so later. I fail to understand how that is going to help anything. The other peice of advice they gave me was to disconnect my phone line in 510-357, and apply for another number that is attached to a different switch (preferably a 5ESS, or a 1AESS). The technician also told me that he believed the DMS was slower than the other switches, but I'm not so sure about that either. So can anyone tell me what might be causing this condition? trent@netcom.com ------------------------------ From: RANDY@MPA15AB.mv-oc.Unisys.COM Date: Tue, 25 Jan 1994 20:04:00 GMT Subject: Re: Sprint (Dvorak) Modem Offer Just an update, and an observation. I called Sprint in September to sign up for the offer (and was also assured it was a 9600 baud external modem). My line was switched to Sprint. I never received the modem, and every time I called I was told something different. For a few months, I was told the modem would be shipped, but that there had been problems getting it shipped automatically. Then, I was told that I was not eligable for the modem, because 'the offer expired on October 1.' Finally, I talked to a supervisor, and we went through the notes on my account. It seems my original call was taken by someone not familiar with the offer, and this person failed to sign me up for the modem (but did switch my line). When I pointed out that I had called to sign up for the modem before the offer expired, and that it was no fault of mine if the Sprint rep didn't do it right, the supervisor promised to contact the manager in charge (no longer Diane Worthy, it seems) and appeal. This was at the end of last year, and I still have not heard anything. I must say this entire experience has lowered my estimation of Sprint quite a bit.

This is interesting. I live in an NPA (405) that uses 1 + 7D for calls within the NPA. I've not heard any announcement on changing this here.

I heard that all area codes have either 0 or 1 as the second digit and so do all special numbers such as 911 and 411. Is "360" possible? hiro@lynx.com [TELECOM Digest Editor's Note: In the past, what you said was correct. The supply of combinations in the form you suggest is now exhausted and area codes now being issued look like almost any other three digit number. Telcos did a lot of things in the past they no longer can afford the luxury of doing such as never assigning the same prefix in two adjacent area codes. They cut that out about fifteen years ago. Until about thirty years ago, the three digit prefixes were letters of the alphabet rather than numbers and those letters were the first three letters of words. As the usable supply of those became in short supply exchange names were ditched in lieu of using all numbers. Time marches on. Who knows what our phone numbers will look like a decade from now.

At the first level you have to know what the single user has as for computer. Trivial but crucial. The least common denominator is that both parties have a terminal adapter (TA) that acts as a modem. Quick, fast and simple, but expensive. If you need IP (for ftp, X, ...) it is more complicated. Like for modems, the TA supports the passage of slip or ppp protocols, but both computers should support that protocol. And that is the start of the problems. Unix boxes are generally able to support these protocols. PC, Mac, Atari, Amiga, ... don't directly, but some of the networks of them support IP. So the level of interaction is much like a router between networks. Another level is the fact that there are "cheap" PC cards on the market which appear now (in Europe, at least...). There are fossil, packet driver, ndis, odi drivers for some of them, I investigate those now but it is still quite tricky for me. I am also interested to hear other opinions/solutions.

I know a remember a bit about it, having worked on it about 12 years ago. The Standard A service has analog scpc voice and 50b/s telex, which is carried tdm shore-to-ship and tdma ship-to-shore. Each ocean region has an NCS which coordinates use of the satellite channels. There are one or more shore stations in each ocean region. The shore station ties the network into the public phone and telex systems of the country it resides in. Voice call setups, as far as I can recall, are done out of band. There are one or more special signalling channels that are used to initiate calls from ships. I seem to recall that access to these channels is aloha. If I'm not mistaken, the satellite receives C-band from the shore stations, and relays to ships on L-band. It receives on L-band from ships and relays to shore stations on C-band. The ship terminal has a parabolic dish antenna about two feet in diameter. There is a servo to keep it aimed at the satellite. Price of a ship terminal was around $50K ten years ago. Don't know what it is now There is another service offered by Inmarsat -- Standard C. It is data only at 600b/s. Don't know if it's 5 or 7 bit. I believe the ship-side interface here is also L-band. The antenna is an omnidirectional plate about 6 inches in diameter. I don't think it's a spread spectrum system, but there is lots of DSP because the power is low and the antenna has very little gain. > I'm also curious about the security of the whole system (both the > 'listening in to calls' security and the 'making calls at the expense > of another user' part). No security. No encryption. Everything in the open. The ship ID is burned in a ROM in the terminal. You might be able to fake it out. But if you use a true ship ID (which you'd have to) and that ship is in your ocean, the call setup might get tangled up.

There are different types of Inmarsat service called A, C, and M. The cost structures are different and it really depends on what type of data you need to send and where you are.

The anonymous call It's not necessarily a matter of being "clueless". AT&T runs credit checks on people requesting calling cards, and they are considerably less tolerant of newcomers than, say, Citibank. If you have established perfect credit already, then you may be able to just call AT&T and ask. Otherwise, forget it. (Sprint, however, seems to be better about this sort of thing.) > The anonymous call crowd? Well, if you share a phone line with someone else, it is often nice to be able to make telephone calls without giving the other person the ability to track them.

Does anyone have a table? > V&H data only shows it as Oakland, CA, which is true. I don't know if this is specifically related, but a few years ago, Southwestern Bell Mobile Systems in St. Louis was unable, for whatever reason, to bill (900) numbers, collect calls, and third-party billed long distance calls to cellular phones, IF the call went through a long-distance carrier. If the call was Long Distance (that is, collect or third-party) and handled by Southwestern Bell, you'd get a nasty phone call a few days later, demanding that you allow the call to be billed somewhere else. SWBMS has since blocked collect and third-party calls from being billed to cellular phones, and, I think, (900) numbers too. Right after they began doing this, though, it was possible to call the company and tell them that you no longer wanted to block these calls. The customer-service drone, assuming that the block had been ordered by the customer, would generally remove it on the spot. Since SWB would call you when you made a call of this sort that was handled by them, and (900) and LD carrier calls were not billed, my assumption is that ANI just doesn't work on some (all?) cellular systems. Anyone know why, other than to save money? Is this a limitation of the technology, or something that can be configured either way? T.

Phone service to Northridge, the hardest-hit region, and the surrounding neighborhoods is *still* choked by AT&T, et al., as of this writing, according to KFWB Newsradio. Pac*Bell reports in excess of 35 million calls per hour completed at the height of the disaster; this number is slowly receding with time. I can't really speculate successfully on how much help the Internet was in getting calls through to relatives from out of state, but if the traffic on ca.earthquakes is any indication, a number of people used that forum for urgent messages like "My brother is in Chatsworth, can you contact him?" Since the passage of California Assembly Bill AB1645, state business, pending bills, and announcements are available on the Internet (supposedly sen.ca.gov and asm.ca.gov -- mail me for further info). There's also a couple of finger servers (quake@andreas.wr.usgs.gov and quake@geophys.washington.edu) and a special telnet server (telnet oes1.oes.ca.gov 5501) for earthquake info and other announcements. One poster reported calling a local radio station with information he received by ftp'ing it from the state announcement server (above); the person at the other end screeched WE NEED FATALITY STATISTICS DO YOU HAVE THESE NUMBERS???? or something equally obnoxious. Death sells, I guess. > On another note, I just wanted to mention how great technology is. > I've been following the earthquake info on the Internet Relay Chat and > on CompuServe.

This site's not very good for monitoring that sort of thing -- I'm two UUCP hops away from the Internet. Sometimes news takes a day to reach here after it's reached the main California sites, though mail is much faster. However, my UUCP feed stayed up where Netcom crashed. To be fair to the Netcom people, they were up (if unreliably) in pretty short order, all things considered. For those people still wondering about relatives in the San Fernando Valley who haven't gotten through yet, you can e-mail me and I'll try and get through for you. Robert L.

That's the premise of the International Internet Association (IIA), a nonprofit group that promises to give "anyone on the planet free Internet access," according to IIA Executive Director Max Robbins. Robbins held a press conference here today to flesh out what has been the Net's biggest mystery for the past several weeks. When IIA first announced its plan to provide free Internet access, the group was assailed as being a scam. Adding fuel that speculation was the fact that in order to process your account application, the IIA required that you provide them with a credit card number (preferably your own). Oh yeah, there were also those other little niggling details that didn't add up, such as the IIA's address in D.C. really being a rented post office box and that their net domain -- IIA.ORG -- didn't seem to exist. Robbins, dressed in a rafish multi-colored cardigan sweater and IIA turtle-neck T-shirt, acknowledged that his organization made "some rookie mistakes" in the beginning. But he insisted all was above board. He said the credit card number was needed because the company providing the 800 number access to the IIA host computers needed it to bill people, at 20 cents per minute. "But we always told people that's what it was for," he said. "And we do have a direct dial in number so people don't have to use the 800 number if they don't want to," he said. The organization was swamped with applications, some 40,000 have flooded in since November, Robbins said. But only 16,000 have actually been given accounts. He says they're working on the backlog. But let's cut to the chase. Robbins is a young, idealistic do-gooder that thinks the Internet has been co-opted by its techie users and his mission is to set it free. He figures that if he provides free Internet access to "the great unwashed" of the world, the Net will be a better place. About the only thing this self proclaimed "Idaho farm boy" (with a Georgetown University degree) didn't say is that his efforts would eventually bring world peace. May the force be with you, Max. The organization, which hasn't yet set any standards or procedures for taking on members, as any normal association is want to do, is being underwritten, apparently, but the good will of IDT, an international call-back racket out of New Jersey. The IDT scheme is brilliant. The company offers international callers the ability to call into the U.S. (on an 800 number), whereby, the IDT computers call your number back and give you dialtone from the good ol' U.S. of A. Using that dial tone, you can then make calls to anywhere in the world, which (technically) look as they they've originated from the U.S. Begin to get the picture? The upshot is that if your company is located in Rangoon, you can bypass the outrageous long distance rates that Rangoon Telecom and Telegraph normally charges, instead getting rates more in line with AT&T. IDT, which has received its share of grief from several countries for taking hard currency straight from their pockets, is headed Howard Jonas. For all its talk of good will and free access, the IIA seems to be nothing more than a front-loaded, money making machine for Jonas. The guy is a sharp entrepreneur and he saw dollar signs in those free IIA accounts. By providing the 800 number (which most people still think is always a free call) he saw a way to generate millions of dollars from anxious users thinking they were getting "free" Internet accounts. You do the math: Figure 40,000 users (if the IIA grows no bigger than current applications) dialing in 10 hours a month. If they use the 800 number that whole time, IDT racks in a whopping $4.8 million PER MONTH in access fees alone. Free my ass. Just how much is Jonas tied into the organization? Well, IIA lists their administrative offices being headquarted at 294 State St., Hackensack, N.J. Funny thing, but that's the same address as Jonas' company. The IIA "public relations" person at the press conference, Steve Rowe, pulls in a paycheck from ... damn, you guessed it, IDT. And the boxes and wires that make up IIA's technology base have the same serial numbers listed in IDT's inventory data base and insurance papers. With all this free shit being given away, how does Robbins pay the rent? "I do some work for IDT," he said. "But we've had enough donations come in so that it basically pays my salary.," You have to admit, this kid Robbins is well meaning, if out to lunch, or maybe his idealism is just way out in front of his common sense. The group said it's supposed to have 501(c)3 status. Legally that makes them a charity. But in their press kit, under the "facilities" heading is an address for "Lobbying." Non-profits listed as 501(c)3 are expressly forbidden from lobbying, it makes the IRS nervous to think a charity would take money from my grandmother and then use it to take Congressmen to expensive lunches or send them to exotic resorts for speaking engagements. I pressed young Robbins on this apparent flaw: "Well, that's not really 'lobbying' in the pure sense of the word," he said. Turns out his idea of lobbying is what Apple likes to call "evangelism." Oh, did I mention that the "lobbying" office address is really home to the IIA lawyer? It is. So, does an organization like IIA do when demand outstrips supply? It goes begging. Literally. Only Robbins doesn't call it that. IIA has "place a bid for services" with U.S. telecommunications and service providers, he says. But when asked how he defined the word "bid," Robbins said: "Well, we asked them if they wanted to give us service." In other words, he wants companies to donate time or materials out of the goodness of their hearts. Robbins justifies this hat-in-hand procurement process by claiming that companies now making money off providing Internet service "have an obligation to give something back to the people." The world would be a better place, he said. Honest. In the meantime, Jonas is waiting in the wings, with some 16,000 and counting credit card numbers, listening to the sound of the "unwashed masses" dialing in, throwing money at his company's bottom line. It's all legal, all very shrewd. And Robbins? Hell, he has a good heart, some big dreams, and an impossible task. Write him, won't you: max@iia.org Or send a check ... if the charity status holds up, you can claim it on your taxes, right there under the heading: Donation to World Peace.

A number of questions remained unanswered between us, so I am posting a summary of our discussions and the questions that we have. Anyone who is willing to contribute: please do so. Preferably by posting, but if you cannot post, email me and I will summarize in a future post. Special thanks to G. Trevor Foo (foo@buvax.barry.edu) for his contributions. Driving forces for the proliferation of telecommuting: Technology: For example, the advent of low priced desktop videoconferencing equipment and the recent movements in the U.S. for a national information infrastructure. The LINK Resourse, a telecommuting research firm, states that employees are spending an increasing amount of money on acquiring their own equuipment to telecommute. From 1991 to 1992, PCs sold to information workers have increased by 27%. Traffic problems: No need to elaborate: costs, time, environment ... Job mobility: Lifetime employment means moving once to the town of your employer and never having traffic problems again. Planning to switch jobs means living where you want to live, independent of where your job is located because after a few years you will have another job somewhere else anyway. Women's (and men's) lib: More flexibility in the daily schedule, for both partners, makes it easier to both have a career and children. Changing management culture: Output oriented management instead of process (attendance) oriented management. This is a requirement, telecommuting is not going to work well without it. Size of business that will especially adopt (and benefit from) telecommuting: Small organizations: - small businesses have a less formal organizational culture, less bureaucracy, than larger organizations. - innovation is easier and more common, new technologies are adopted faster. - they have less rigid operating procedures. Large organizations: - large businesses are changing management culture and desperately looking for ways to become more efficient. - another important condition for effective telecommuting is specialization: in a small organization, the workers tend to be less specialized. When someone has more different tasks, more contact with co-workers is needed. - large organisations are familiar with the use of elctronic links between co-workers, possibly to the extent that they will not know if a co-worker is at home or in the office. Numbers and growth: Present estimates of the size of the potential telecommuting work force range from 30% to 45% of the total work force in highly industrialized countries. This does not mean that 30% or 45% of the _work_ is telecommutable. Many of the workers will telecommute only part of the week. The portion of the total amount of work that could be considered telecommutable is probably less (does anyone have a hunch about a figure for this?). The present research seems to start from jobs and criteria as they are now, allowing for growth of telecommuting on the basis of growing acceptance of technologies and growing political concern. It would be useful to have a prediction of how other factors may change. There are developments in society that will influence the telecommuting potential in the years to come: - Industrial jobs are decreasing in number as processes are automated. Jobs in commerce, automation, consultancy and other services are increasing. - Not only technology develops, but also people get more used to technology for communication. The need for personal meetings will never disappear, but become less over the years to come. We have not found a way to calculate a figure for the impact of these changes. Anyone have ideas on this? A thought: if there are figures for the penetration of email and fax and for the growth of internet, and if there are predictions for how those figures will develop in the future, would that information be useful to say something about the rate at which technology becomes accepted? Of course, that does not solve the equation yet, as there are more unknown variables. Like the necessary change in the culture and management style of organizations (output driven rather than process driven). As I said, any comments are appreciated. koos de heer - centrum voor informatieverwerking koos@cvi.ns.nl tel. ++31.30.924860 ------------------------------ From: mstrange@fonorola.net (Strangelove Press) Subject: Internet Business Users Group Date: Thu, 27 Jan 94 9:16:55 EST Internet Business Users Group; Sponsored by the publishers of THE INTERNET BUSINESS JOURNAL.

In addition to the English version you see here, it will also be issued in Spanish. MCI OFFERS LONG DISTANCE HELP TO EARTHQUAKE VICTIMS WASHINGTON, D.C., January 25, 1994 -- Concerned about the hardships its customers are facing as a result of the earthquake in the Los Angeles area, MCI has announced it will offer special payment options for earthquake victims. Those directly affected by the earthquake should call MCI toll-free, 1-800-444-1828, Monday through Thursday from 5am-9pm (PST), Friday from 5am-4pm (PST) and Saturday from 5am-2pm (PST). Callers from impacted areas are then connected to an MCI Financial Services Representative who will counsel them and provide payment advice to those families concerned about paying their MCI long distance bills. To help earthquake victims, MCI also has opened a Mobile Communications Center in San Fernando, CA. The mobile center, with 24 phones, allows victims of the earthquake who are without phone service to make long distance phone calls on MCI's network free of charge. MCI, headquartered in Washington, D.C., is the nation's second-largest long distance provider. ------------------------------ From: D1749@AppleLink.Apple.COM (Disini SW, Emmanuel Disini,CST) Subject: Wiretapping Problems Date: 27 Jan 1994 03:06:48 -0600 Organization: UTexas Mail-to-News Gateway Greetings, I am a bit concerned that my phone could be tapped (I am located in Manila, where wire-tapping laws are not enforced all that well). Is there some way I can tell that my phone has been tapped? My guess is that there should be some drop in ambient voltage (on one of the RJ-11 leads- TIP? RING?) if a tap is placed on your phone. However if the wiretap is already in place and I look at the voltage after the tap has been installed, I would not be able to detect it, right? Pls cc your responses to d1749@applelink.apple.com, as I don't get this newsgroup.

Forwarded message from PC SprintMail: Contact: Jim Bowman (O) 913-967-3675 Gerry Simone (O) 202-828-7423 SPRINT TO PROVIDE SONET ACROSS NORTH AMERICA FOR INTERNATIONAL CARRIERS WASHINGTON, D.C., Jan. 22, 1994 -- Sprint will provide SONET (synchronous optical network) transit service across North America by the end of 1994 for the 31 European and Asian carriers forming a multilateral group, the company told representatives of the group in meetings this week. At that time Sprint's international dedicated transit route through North America will be predominantly SONET, and it will be all-SONET in 1995, when synchronous digital hierarchy -- the international equivalent of SONET -- cables will connect the United States with both Europe and Asia. SONET is the emerging transport standard of the Information Superhighway. It carries vastly larger quantities of traffic than most current transport equipment, at speeds up to 20 times faster. Sprint announced its SONET deployment plan as part of its overall broadband strategy in September 1992, and began deploying SONET equipment on its network in 1993. Sprint's SONET deployment is increasing network capacity for rapidly developing international and domestic traffic loads, moving voice, image, data and video simultaneously over Sprint's fiber-optic network already in place. In addition, Sprint's broadband network architecture, combined with deployment of an advanced form of SONET equipment only now becoming available, provides for unprecedented levels of reliability. Representatives of the multilateral group met with Sprint International officials this week at the company's headquarters outside Washington, D.C., to review progress and to confirm schedules and revenue projections for the next two years of a three-year pact signed last March. By that agreement, the international carriers receive preferred rates and service guarantees for transit of international calls across North America. Sprint's price and performance guarantees are available to all signatory companies of the multilateral group for a period of 25 years, a significant benefit for smaller companies that now can enjoy the same volume pricing and associated benefits previously only available to the largest carriers. The value to Sprint is estimated in the tens of millions of dollars. "The technology and capacity of Sprint's advanced fiber-optic network allows us to provide many services for other carriers, including dedicated transit services for overseas carriers since 1989," said Paolo Guidi, president of Sprint International. "Many of the companies in the multilateral group have been Sprint customers for years, and they already were familiar with Sprint's superior quality," Guidi added. "Now, they will see us take that quality to a speed and performance level as yet unattained by other global carriers." Sprint is a diversified international telecommunications company with more than $10 billion in annual revenues and the United States' only nationwide all-digital, fiber-optic network. Its divisions provide global long distance voice, data and video products and services, local telephone services to more than 6 million subscriber lines in 19 states, and cellular operations that serve 42 metropolitan markets and more than 50 rural service areas.

Access to TAM from Major eMail Service Providers The TIES Auto-Answering Mailbox (TAM) is accessible from several major email service providers. ACCESS FROM MCI MCI users can access the TAM through MCI's facilities for access to other mail systems (EMS). The TAM can be accessed through MCI's Internet gateway. You can then download documents from your MCI mailbox using a file transfer program in your communications package (e.g. Kermit or Zmodem). If you have problems with one gateway, please try the other. ACCESS FROM MCI MAIL VIA INTERNET: 1. At COMMAND, type CREATE 2. At TO, type ITUDOC followed by EMS in parentheses. For example, TO: ITUDOC (EMS) 3. At the prompt EMS: type INTERNET. For example, EMS: INTERNET 4. At MBX: type itudoc@itu.ch. For example, MBX: itudoc@itu.ch 5. At the next MBX: type return to end addressing 6.

More importantly, from my point of view, the quake will force many Angelenos to try telecommuting. I'd like to know about the telecommuting centers that exist today in the LA area, and any new plans for such centers in the aftermath of the quake. How many are there? How big? What sort of equipment do they have? Has anyone in government thought about this? How about entrepreneurs? If I were in LA right now, I'd be looking into setting up a telecommuting center myself ... Mike Lanza ------------------------------ From: HO JUNYA Subject: Cheap, Practical Notch Filtering and Frequency Shifting Methods Date: Thu, 27 Jan 1994 02:37:49 -0500 I am looking for cheap and practical ways of filtering a telephone line's usable audio bandwidth into a number of segments or notches (somewhere between 8 and 16 or more?), and multiplying or shifting each segment into a new block of frequencies, (this mapping will be determined beforehand) with as little noise or distortion as practical. (this would theoretically be used to 'scramble' a voice conversation) This is for an engineering design course, where we are to build a working (mostly hardware) model of something unique (or somewhat unique) in one term (about 2.5 months left). An example of what I mean follows: Say the bandwidth to be used is 0Hz - 4KHz, and I will use four segments: 0-1KHz, 1-2KHz, 2-3KHz, 3-4KHz. after filtering out each segment, say my mapping instructions dictate that I should map the segments as such: the 1st to the 4th segment, the 4th to the 2nd segment, the 2nd to the 3rd segment, and the 3rd segment to the 1st segment. (so the original 0-1KHz segment gets shifted to 3-4KHz, the original 3-4KHz segment gets shifted to 1-2Khz, and so on) There aren't really set restrictions on this - (ie, is it easier to shift these segments after converting them from analog to digital signals?) - as long as it would work :-) As an aside, the mapping will be done using a hardware RNG. Any comments or suggestions are most appreciated. Thanks, Junya hojunya@ecf.toronto.edu ------------------------------ Date: Wed, 26 Jan 1994 17:33:23 -0500 From: goudreau@dg-rtp.dg.com (Bob Goudreau) Subject: Telcos Start Warning Customers About New Area Codes In the past, some people have ventured the opinion that the general telephone-using population won't even notice the coming of non-N{01}X area codes in the North American Numbering Plan starting next year. However, there is at least one telco that apparently disagrees. My most recent phone bill included the usual _Southern_Bell_News_ newsletter, which had the following as its uncopyrighed cover story, so I assume that Southern Bell wants to get the word out as widely as possible: WHEN THE NEW AREA CODES ARRIVE, THEY'LL LOOK A LITTLE FUNNY Don't Be Surprised If You Begin Seeing Area Codes That Don't Look Like Area Codes! [In Box:] DON'T LET IT CATCH YOU BY SURPRISE! The area code numbering plan for North America was established in the 1940s, and has lasted nearly fifty years. Because of the phenomenal growth in telecommunications services by pagers, mobile phones, fax machines and telephone lines, the telecommunications industry is running out of area codes. Therefore, a new area code format for North America is being introduced on _January_1,_1995_ [italics in original text]. The new numbering plan will add 640 new number combinations for area codes by using any number (0 through 9) as the middle digit, instead of restricting the middle digit to a zero or one, as the old plan did. Area codes will remain three digits, like 704 in North Carolina. This change makes new area codes available for _future_ use, and will not change your current area code. New area codes will be added, as they always have, when needed to accommodate growth in telephone lines or communications services. The Customer Guide section in the front of your white pages directory contains area code information for the United States. The change to the new numbering plan will not affect your rates for telephone service. It may, however, make recognizing a geographic location based on the area code more difficult. All the phone companies in North America are working together to make this transition orderly, and to try to ensure that all calls go through. ------------------------------- Bob Goudreau Data General Corporation goudreau@dg-rtp.dg.com 62 Alexander Drive +1 919 248 6231 Research Triangle Park, NC 27709, USA ------------------------------ Date: Thu, 27 Jan 1994 05:05:51 MDT From: Rob Slade Subject: Book Review: "Practical Internetworking with TCP/IP and UNIX" BKPIWTAU.RVW 931130 Addison-Wesley Publishing Co.

For those who need to connect a UNIX machine to the Internet, this is a one-stop reference for most of the basic necessities. The book starts with a historical and conceptual backgrounder on the Internet. This first section also gives technical and even some programming details on the basic IP, TCP and UDP protocols. The technical level is advanced, but fully explained for the perseverent newcomer. Part two is the practical side. Four chapters give the basics of the setup, email, sendmail and other services. For a standard system, this could be almost all you need to get running. Part three covers advanced topics such as the integration of microcomputers, network management and debugging. It is nice to see a work that addresses the issues of micros, which are ubiquitous in the usual workplace. It is equally nice to see a practical approach, such as the suggestion to use terminal emulation if such will fill the bill. (It is amusing to see a mild tendency towards UNIX chauvinism in such subtle ways as the use of the UNIX default lower case filename convention applied to the case insensitive/upper case MS- DOS file system.) Appendices give tips on the use of various Internet services as well as some useful utility program listings.

Are > there other modulation methods known which are still more efficient > from the consideration of bandwidth utilization? Mr. Sinha, It is my understanding that GMSK stands for "Gaussian Minimum-Shift Keying", which is a variant of MSK ("Minimum-Shift Keying"), which in turn is a variant of FSK ("Frequency-Shift Keying"). In FSK, a signal is modulated between two frequencies which are symmetrical about a center frequency. Call the difference between these two frequencies df. In MSK, df is reduced to the minimum value that will get the job done, which turns out to be half the baud rate (i.e., the symbol rate): df = Tb/2 (where Tb = baud rate). This results in the smallest bandwidth for an FSK signal. I believe that GMSK is simply an MSK modulation scheme coupled with gaussian transmit and receive filters. I am confused by your reference to efficient bandwidth methods for spread spectrum systems since these systems purposely widen the bandwidth greatly. Although I couldn't find anything on GMSK in them, the following references may be of help to you: [1] "Digital Communications and Spread Spectrum Systems", Rodger E. Ziemer and Roger L. Peterson. [2] "Digital Communications", John G. Proakis. I hope this information may be of use to you.

Whereas my friend who lives in a different area has a > "1A" switching system, where they DO interact! Well, you probably don't want any excuses or a long history of the pain involved in this area, so here's my nickel summary: 1) The interaction of 3WC and CW evolved over about 5 years in the early 1970s on 1E/1A ESS(tm) switches. Trying to explain the actions of a switch to a customer who only has one input ("flash") at any given point lead to a really elaborate set of somewhat inconsistent modifications to the code, resulting in the current implementation. That implementation works basically as follows -- a) Set up call, flash and place second leg of call. From the moment of flash until the second call has answered, CW will return "busy" to any incoming call. Flash will drop the second call leg. b) After second leg answers, without CW, a flash will drop the second call leg. From the moment of CW alert (the "click" plus tones), a flash will connect to the CW caller, and leave the other two parties talking on your nickel. Another flash (or disconnect by the CW caller) will connect you back to the 3W call. If the CW caller does not disconnect, you can toggle back and forth between 3W and CW calls as frequently as you desire. c) After second leg answers, and CW alert occurs, but you ignore it, and the CW caller abandons the call, there is no 3W call to reach with a flash. But you don't know the caller has abandoned, so the CO "remembers" that you once had CW alert offered and treats a flash as an attempt to reach a CW call anyway (you get reorder, I believe). This failed attempt erases the CW alert "memory", so that future flashes will drop the second leg of the 3W call. d) A side-effect of the "toggle back and forth" of 3W and CW is that, until the CW caller drops off your line, you cannot "drop" the second leg of the 3W call! Try writing that down, along with other interactions. Better yet, try making that a general requirement for all switches, and extend it to other feature interactions, multi-line groups, etc. It's a tough job. That's why 2) Bellcore, in writing generic requirements for switches in the LSSGR, specified a simpler, more easily understood behavior: a) Set-up two legs of 3W call as before. From the point of flashing to set up the second leg UNTIL you flash to drop the second leg, you cannot receive a CW alert -- and callers get a "busy" signal. b) If you drop the second leg, you can now receive CW alert and flash will connect you to the new caller. But until the CW caller drops off of your line, you cannot initiate a 3W call (second leg) -- each flash just toggles you from one call to the other. Much easier to explain to customers, and new switch vendors, than the 1E/1A ESS implementation. That's why the 5ESS(reg. tm) switch acts in this simpler manner -- it's what the TELCO (via Bellcore) specified. {The dime summary would have been half as long :) } > It is a pain that my line is busy during 3WC, because I ordered CW for > the specific reason of NOT loosing calls! Are there any specific > questions I should ask the phone company, or just give up on this one? CW does not alert 100% of the time -- for example, when you pick up the phone and start dialing, CW alerting is blocked. In fact, it will be blocked until your called party answers. Several folks have complained that their CW is "broken" because 1) they receive normal dial tone at the beginning of a call (implying there are no messages), 2) they dial a call and talk for awhile without any CW tones, 3) they go on-hook and then off-hook, only to receive a "messages waiting" interrupted dial tone. Conclusion: CW isn't working!! Fact: They received a call sometime after the first dial tone and before the call was answered, and their incoming call was routed to Voice Mail immediately (no CW). But you do have several options: A) Get a good voice mail system that will get any call where you can't receive the Call Waiting alert. Sometimes CW won't be available with voice mail, and sometimes it will. Either way, callers won't get "busy" during windows when CW is never available, such as during dialing and before answer on any call. If you spend 20 seconds dialing and listening to ringing and only 2 minutes on a call, then callers have a 17% chance of getting busy even without the 3WC problem. B) Ask if a Centrex-like package is available for residential lines. Some TELCOs have these priced in a bundle with Call Hold. Better, if you can, just get the "Call Hold" feature added to your existing features. Call Hold will not interpret "flash" as anything, but will give you dial tone -- from which you can dial a code to "hold" the current call and answer a CW caller or another code to "drop" the second leg of a 3W call. Since you are using explicit codes, the Bellcore restriction of 3WC/CW does not apply, and you can get CW while on a 3W call. (CW will still not work during the time you are dialing and waiting for a call to be answered.) C) Get a second line, with hunting from the first on busy. Avoids the CW blockage during dialing/unanswered-call periods, and you can drop the CW feature. Or retain it and be able to be on 4 calls at once! D) (The one I use.) Get ISDN. Even with 1 CSV B-channel, ISDN can support 3W calls explicitly (push the CONFerence button) and also support alerting of another incoming call (push the new call appearance to answer). You can drop the new incoming call with another button. You can even MERGE the incoming call with your current outgoing call. I'm sure I missed some other ideas ...

Organization: Switchboard BBS - +1 514 334 7883 Taken from the {Montreal Gazette}, 1/1/94 By Alexander Norris and Aaron Derfel One of Canada's main telecomunications satellites accidentelly spun out of control yesterday afternoon, cutting off long distance phone links to northern Canada and sending newspapers, radio and televisio stations scrambling to get out the news. In-house telecommunications services used by large companies - including stock quotations sent to brokers' offices -- also conked out when the Anik E-1 satellite tumbled out of it's axis at abot 12:40PM. And local affiliates of the CTV television network, which rely on the satellite for national programs, were restricted to local shows until about 4 PM, said Barry Turner, vice-president for sales and marketing at Telesat Canada, which owns and operates the satellite. In all, Turner said, about 3,000 corporate customers were affected. Service to most customers was restored at about 8 PM. But one hour later at 9:10PM, Canada's other major communications satellite Anik E-2, also cartwheeled out of control, knocking CBC newsworld and other national speciality cable TV channels off the air and affecting CBC and CTV operations. Partial service, with signals carried by fiber-optic cable, was being restored in some centres across Canada. "We're working on it, but it doesn't look good," Jim Spendlove, a Telesat official, said early today, suggesting that it might be much more difficlt to fix it that it was to get Anik E-1 working again. Chris Frank, Telesat's director of public affairs, conceded the company might have to issue rebated to the tune of "hundreds of thousands of dollards" because of the Anik E-1 service disruption. "We're going to have to rely on our 20-year history of top-line service to convince our customers to stay with us," Turner saidin an interview last night."It is a blow to us in terms of our credibility, but we're working hard to mitigate it". LAUNCHED IN 1991 Telesat officials said the Anik E-1 problem originated with an electronic failiure inside the $300-million satellite, which was launched in 1991 and hovers 36,000 kilometers above the equator. The malfunction affected a device that keeps the satellite in s stationary position above the earth. That sent the satellite spinning, then wobbling, causing it to move out of alignment with tousands of transmitting facilities and receiving dishes on the ground in Canada. The news business was hit particularly hard. "You just can't find a decent satellite these days," grumbled Eric Siblin, a copy editor at the Montreal office of the Canadian Press national news-gathering co-operative, which stopped providing dispatches to about 100 newspapers because of the malfunction. "All we need is a couple of carrier pigeons, some long string and two tin cans, and we'll have a state-of-the-art 19th-century wire service." Aside from CTV and the Canadian Press, CP affiliate Broadcast News was also affected, as were CBC Newsworld's internal feeds, the Reuters wire service Standart Broadcast News and the Toronto Globe and Mail. The outage interfered with production of today's Gazette, but all regular features are included in today's editions except some commodities listings. At the Globe - which uses Anik E-1 to beam its paper to printing presses accross the country -- managers had made plans to fly printing plates to Halifax, Boucherville, Brandon, Man., Calgary and Vancouver -- but abandoned them when satellite service resumed. The interruption also affected abot 450 subscribers to the broadcast news service, said Wayne Waldroff, general manager of BN. Some feeds from CTV and french-language TV-5 were switched to the Anik E-2 satellite, Telesat spokesman Christine Bailey said, before it went kaput. MAKING LOCAL CALLS Normand Toupin, a Bell Canada spokesman, said up to 30,000 households throughout northern Quebec and Ontario and the entire Yukon and Northwest Territories were restricted to making local calls during the Anik E-1 outage. Telesat Canada does $200 million in sales every year and is owned by Alouette Telecommunications Inc., a consortium controlled by Spar Aerospace Inc., which made the satellite, and the Stentor group of Canadian phone companies. ------ Why is it that only the Canadian satellites were affected? The news tonigh said that an electromagnatic storm was responsible for the problems. Wouldn't such a storm affect other satellites also? PS: Typos are mine. (As always.)

I also heard that in the movie "Forever Young" recently. I was wondering how the switchboards worked then. Were the switchboards actually divided geographically? Can anyone give a history lesson? Dahe Chen Mentor Graphics Corporation 15 Independence Boulevard Warren, New Jersey 07059 (908)604-0888, (908)580-1906 (fax) [TELECOM Digest Editor's Note: Yes, switchboards were 'divided up geographically'. Until about 1960, the three digit prefixes we have now were either the first three letters of a word or sometimes the first two letters of a word and a single digit. Smaller towns had a single switchboard and larger places like Chicago had many switch- boards loated in different areas of the town just as now there are different switching centers in a large town. When telephone calls were processed entirely by operators, the various switchboards were all connected together in the same way the switching machines of today are all interconnected. If you asked the operator for a number which was not on the same switchboard as yourself, the operator plugged into a certain jack on the board which connected the call to the desired switchboard, then she would tell the operator at the distant board what number was desired. Each of the switchboards had names, just as each of the switching centers today have numbers assigned to them. If the number you passed to the operator verbally was not the name of the switchboard you were using, the instant she heard the name of the switchboard desired she was already plugging into the associated jack and by the time you recited the numbers following the name, she generally had the operator from the distant switchboard on the line. When connections were handled entirely by operators, the length of time from you going off hook to getting your party on the line was about the same as today. The light above your jack on the switchboard illuminated when your phone went off hook. By the time you got the receiver to your ear, it is likely the operator was already there asking 'number please?' and because she knew almost by heart where every jack to all other switchboards was located on *her* switchboard as soon as she heard the exchange name she was up there. It would be a brief, interactive conversation of just seconds in length: (you go off hook, operator responded usually in five seconds or less) "Number please?" (operator speaking to you) "Wabash 3456" (you speaking to operator) "Thank you" (operator speaking to you) If you were also on the Wabash switchboard your operator would then continue: Line is ringing ... or Line is busy. There was no audible busy tone and only certain swithboards had audible ringing tones. If the first response, the operator would pull the ringing key forward again about every fifteen seconds or so for two or three seconds and after maybe a minute of this (if there was no answer) would say, "Line doesn't respond" or "Line doesn't answer." If she told you "Line is busy" of course you just hung up the phone and tried again later. Courteous subscribers would say thank you first, then hang up; discourteous subscribers would just slam the phone down or perhaps curse at the operator in the process. If you were not on the Wabash switchboard then after saying "thank you" your operator would already be plugged into Wabash waiting for the 'click sound' which meant the distant operator (who did not speak up at that point) was on the line, and your operator would say merely, "3456" (operator speaking to the operator at Wabash switchboard. The audible sounds heard were a 'chunk' which meant the distant operator had started pulling the ringing key and your operator would respond with "Line is ringing". Or, a 'tick-tick' meant the distant operator had touched the tip of her cord to the sleeve of the jack and found the line busy. Your operator on hearing that would report "Line is busy". If she did not pick up on it, the distant operator would occassionally speak up and say merely "BY" (pronounced 'bee-why') which meant busy. After somewhere around a minute, if your party had not answered and your operator had not told you there was no response, then the distant operator would speak up and say merely "DA" which was pronounced 'dee-a') which meant doesn't answer. Either way your operator would then report to you the status.) On a few occassions when the calling traffic was very heavy, your operator might attempt to connect to the distant switchboard only to find none of her jacks going to that switchboard to be available and she would advise you that no circuits were available going there at this time. Or if she got through to the distant end but *they* were out of switchboard cords temporarily, then the distant operator would respond to your operator by saying 'NC' (enn-see) which meant no circuits right now. If the distant phone was out of order, the operator's reply to each other was 'OD" (oh-dee). "NW" was not a good number (no such number in service) and 'denied' was the response when the called subscriber had been cut off for non-payment, or what we sometimes call a credit disconnect. If you asked for 'Information' you were connected to a room full of clerks who wore headsets with *very long* cords on them who walked around in a rather large room with stacks of phone books everywhere plus the most recent (handwritten) list of updates, number changes, etc. Asking for the 'Business Office' got you the reps who would discuss your bill, etc by pulling manual, handwritten file folders out of row after row of racks which closely resembled library stacks. You also would ask the operator for Repair Service. If you wanted to make a long distance call you asked for 'Long Distance' and you were connected to other operators who handled that exclusively from a different switchboard. Your operator would stay on the line until long distance answered and pass your number to the LD operator to avoid the possibility of you 'accidentally' giving the wrong number for billing purposes when it was requested. A long distance call consisted of a series of switchboards hooked together from one place in the country to another. A Chicagoan calling Los Angeles -- let us assume 'Hollywood 2000' which was the number of the Paramount switchboard -- would tell LD he wanted that number in Los Angeles. She would plug into a jack, wait a few seconds and presently an operator would answer 'St. Louis'. "...St. Louis, this is Chicago, give me Kansas City ...", and after a few seconds, an operator would answer 'Kansas City' and your operator would say, "...Kansas City, this is Chicago, give me Denver ..." when Denver answered, the operator asked for Salt Lake; and from there she would ask for Los Angeles. Finally when Los Angeles answered your operator would ask for Hollywood 2000, and presently the switchboard at Paramount would answer. Now your call was connected, and after a minute or so, the line would go dead!!! You'd flash your hook furiously and your local operator would answer. "Operator! you cut me off!" Your operator would jiggle the ringing key and get long distance, "Operator! this is the xxx operator. You cut my party off!" ...."No, I did not cut your party off operator, they are still up here ..." and she would jiggle the ringing key until St. Louis answered: "St. Louis! you cut my party off!" "No I did not, they are still up here." Kansas City, Denver, Salt Lake and finally Los Angeles, always the same answer, "I did not cut your party off, they are still up here." Finally they'd all get reconnected back to the Paramount switchboard and blame *her*, and of course she had no one else to pass the blame to. It could have been any one of the five or six operators on the line who (a) got the false supervision signal or (b) just accidentally yanked the wrong cord from your local operator on one end to Paramount on the other, but none of them would admit it. Long distance charge tickets were all written up by hand and time-stamped in a small clock on the switchboards; when a ticket was stamped out, it went on a spindle and about every fifteen minutes a clerk from the billing department came through with a cart on wheels and collected all the tickets which were filed in the file folders so the service reps could talk to customers about them and the legions of bookkeepers could post them in ledgers and mail out bills.

I have a CONTEL pager that uses an access numb er that is normally long distance from our C.O., but uses screened billing so charges to access the end to end pager number never appear on our Contel bill. Due to the earthquake in San Fernando Valley, I had to relocate temporarily to look after my 88 year old mother and see to repairs of our family home in Reseda -- two miles from the epicenter of the quake. I called GTE and in turn they called Contel and gave me a free access number on my pager for the next 30 days to help out. I thought that was very nice of them considering all of the horror stories that I'd seen and hear on the net. Contel and GTE are both licensed on VHF 158.1 Mhz. but in different geographical locations so after we got to the right people -- consumer service I might add -- the whole thing was done within an hour!

Darcos & Company, Silver Spring, MD USA Summary from "N.Y. Firm Makes Bid For Unicel" by John Burgess {Washington Post}, Jan 27, Page D11 Nationwide Cellular Service, Inc. of Valley Stream, NY, a cellular reseller with about $115 million in 1991 sales and 175,000 customers in several cities plus the Washington DC area, on Jan 26 tentatively agreed to buy Columbia MD-based Unicell America, Inc., a competing reseller with about 12,000 customers in the DC/MD Eastern Shore/Delaware corridor, for $4.6 million. A cellular reseller is someone who buys blocks of numbers from a cellular carrier at wholesale discount then resells them at retail markup. In 1991 Nationwide bought GTE's Washington reseller. As such, only one other reseller -- for Motorola purchasers -- would exist in the area. This worries Chicago-Based Consulting firm Prarie Street Partners, which has objected to the merger, claiming it could violate Maryland's antitrust laws. MD Assistant Attorney General Alan Barr says he is interested but can't promise that the deal is being examined. Unicell is a division of Walker Telecommunications Corp., which is currently undergoing Chapter 11 bankruptcy. The court would have to approve the sale. Neither the trustee for Walker nor a spokesman for Nationwide had any comment. Paul Robinson - Paul@TDR.COM ------------------------------ From: daveh@teal.csn.org (Dave Hughes) Subject: 'Arbitrage' PUC Rule? Organization: Colorado SuperNet, Inc. Date: Sat, 29 Jan 1994 20:35:40 GMT I learned last week of an obscure rule which somebody -- allegedly the Colorado PUC Staff -- is putting in a set of rules tightening up the expansion of rural local calling areas. I had never heard of the term arbitrage with respect to phone connections before, and I am a novice on PUC rule making, but if this rule does what I think it will, I will be before the PUC with bells on complaining as loudly as I can, on behalf of ordinary rural folk trying to use grass roots, low cost, data telecom. Let me explain an example I used, which a PUC-rule-knowledgable person said would be prohibited under the rule. I have been asked to set up a powerful small computer bulletin board in a rural town -- powerful enough to have one or more lines coming in via US West, and one with TCP/IP and SLIP going out another via a local phone company whose local calling area reaches a city where there is an Internet server. Those users who live in a three county area served with a local call to the BBS via US West can, on occassion (not always, for the BBS will serve locally), telnet out via SLIP to the Internet, and e-mail and news can flow into the BBS. My friend says that is a form of 'abitrage' and will be prohibited under the new rule. There is no alternative, especially in a sparse area, to the 24 hour SLIP connection over a local circuit, $50 a month, to the Internet service, which will charge $250 a month, or $300 total, except to order a bigger bucks ($350 dedicated 56kb line + $800 internet or $1,150 a month) connection -- four times as much. And for an area where it would be a year or more before the traffic would max out even a 14.4 SLIP modem link, yhere is a real diference in a little rural area between $3,600 and $15,000 a year. So what is artbitrage, really? And how can I fight a rule whcih only will have the effect of having *no* service set up, if it can't be entered at the low cost level? Dave Hughes [TELECOM Digest Editor's Note: The dictionary defines arbitrage as the simultaneous purchase and resale of some commodity or service in order to benefit from the difference in price between the buying and selling market. I don't think that really applies in the scenario as you have described it. You are not purchasing and reselling the same service. You are purchasing telephone service in order to sell (not re-sell) Internet connectivity. Yes, you are reselling Internet conn- ectivity from whoemever your vendor is for the same, but you are not purchasing the Internet connectivity from the same vendor as you are purchasing the telephone service, and even if you were you are not purchasing and re-selling 'the same commodity or security'. The tele- phone is a necessary part of your business, but what is really happening is you are using the telephone to receive calls from people who you in turn connect with various information databases which you are authorized to distribute by virtue of your contract with your vendor for Internet stuff. Another important point is that your callers will be getting connected with *you on your computer* then (as you worded it) using telnet -- not a telephone company in the world offers it -- to connect with other places. Since no telco offers telnet -- either the hardware to do it or the software -- you are not reselling what the telco is selling you. Telco is selling you carriage, or a transport mechanism; you are using the carriage or transport mechanism to distribute information to your customers. To put it another way, if arbitrage could be defined as loosely as your friend has done it, then every hotel switchboard becomes illegal since the hotel purchases local service from telco at one price and immediatly resells it to guests at some other price. Every privately owned payphone (COCOT) becomes illegal for the same reason. Every pro- vider of information by telephone who accepts telephone calls from customers then uses the telephone to seek the desired information elsewhere becomes illegal. The travel agent who accepts a local telephone call from a client seeking a reservation who accesses the terminal in his office to connect with the mainframe of an airline across the country becomes illegal. Why? Because by the definition of arbitrage your friend is using, the local person avoided a toll call to the airline mainframe across the country by connecting instead on a local call to the agent who in effect purchased a commodity (a phone call to the mainframe somewhere) and immediatly resold the returned results of the carriage to his client. The difference then is telco sells carriage. You sell information. You need carriage to complete the transaction, and telco needs information to be carried in order to complete their transaction. They go together but they are not the same 'security or commodity' regardless of the fact that the actions occur simultaneously. Unfortunatly for the PUC, arbitrage requires the *identical, same* security or commodity. Anyway, *why* is the PUC getting involved in this? You install your computer and you order phone lines for it. If you want FX or some other specialized service you order it and have it installed. Let the telco(s) involved in this tell you they won't do it, and why; make them quote their tariff authority, and if they are unable to do so, then sue them.

I am writing a paper about the telecommunication structures in South Africa. As you may know or not know, the situation in South Africa is extremely interesting. The South African telecommunication structures are very modern (number 22 worldwide), but the problem is that it is going to be a democratic country soon. This demands for example that all black people should be able to get a phone, which is now not at all the case. The South African government is not keen on democratising the telecom-structures and therefore it is beyond any doubt that these telecom-structures will be privatised (black people will not be able to pay the amount asked). If anyone can provide me with some information on "Telecommunications in South Africa", or with adresses of newsgroups that are of any relevance in this matter, please e-mail me.

I'm not sure if calls originating from Manila contain ANI information, but it would be nice if that black box could figure out that I'm calling from Manila, call me back (using some low-cost overseas subscription plan, such as AT&T's Reach out World), and then (using a second telephone line) allow me to dial any number in the US (or the world, for that matter), at US rates. You see, calls from Manila to the US cost $2.25 for the first minute (plus 10% tax), whereas MCI charges 47c/min under the Friends & Family plan. If this works out, I'd be interested in reselling such boxes in Manila. Joel Disini d1749@applelink.apple.com [TELECOM Digest Editor's Note: There is a company which makes such boxes, but like Telepassport (the service I represent which sells the same kind of thing) they depend on identifying your call by the phone number which was dialed to reach the box. Also, they use three-way calling rather than a second line to establish the connections. You call it; by virtue of the incoming ringing signal it calls you back; you enter a passcode and the desired number; it then flashes for the three-way line, places the call and flashes again. If I get some money, I am going to get a few boxes and switch all my Telepassport clients over to my own system. In the meantime Joel, don't re-invent the wheel. Use one of the several existing telephone arbitrage (our word for the day!) outfits around. I'd prefer you use mine but that's your choice.

Email on this is fine. ------------------------------ Date: Sat, 29 Jan 94 12:50:56 EDT From: Michael Jacobs Subject: Area Code 215 to 610 ... Not Mr. Thomas Hinders notes that some persons were having difficulty dialing in to him using the new 610 (Allentown and Southeastern Pennsylvania) area code rather than the former 215 area code. Bell officials (according to a news article in the Allentown Morning Call newspaper) contacted Bellcore (the current NANP administrator) to send an emergency bulletin to all IXC's that such difficulties have been reported. When placing a long-distance call, there are several places where a call can be intercepted and prevented from being completed. One, the caller's CPE (key system unit, private branch exchange, etc.) can be blocking the call to a non-recognized area code (Numbering Plan Area or NPA). Two, the local exchange carrier (RBOC or independent) needs to recognize the call setup and route it appropriately (based on the presence/absence of dialed digit "1" + NPA). Three, the LEC's signalling network provider (not all LEC's operate their own Signal Control Points (the database which instructs the SS7 network and Signal Transfer Point switch)) may not yet havethe new NPA data in their system. Four, the IXC may not have that information in their SCP routing database (I imagine that AT&T does, but there are dozens of smaller carriers that may not yet have gotten the message). Lastly, the LEC in 610 NPA (Bell Atlantic-Pennsylvania and independents ) must take the signalling info from the IXC and route it appropriately. The point here (and my scenario above is merely educated speculation), is that there is a lot of coordination to be made in effecting a NPA change, and that is why they are so well-publicized (including ad- vertisements in nationwide trade and general-circulation periodicals). It should not be suprising that technical glitches will occur. That is why Bell has given a one-year grace period when both area codes will work. This grace period, however, is (according to the article) intended only for end-users and not for IXC's who have had plenty of warning and should have effected the required changes to their systems. Moreover, callers should realize that the telephone system (Bell, GTE, IXC, and independent) is designed, built, and maintained by human beings and will never operate at 100% perfection (due to the conseq- uences of the Law of Diminishing Returns, I should not like to see the size of my phone bill from a company that actually did operate at 100%). Therefore, an educated caller will know how to access other IXC's via the appropriate 10XXX codes, contact an operator for assistance in completing problem calls, or contact repair service to have a line trouble repaired. The telephone companies and their employees work hard to ensure that the calls go through. As an aside, I found it interesting that during the aftermath of the recent ice storm in SE Pennsylvania when Philadelphia Electric had 500,000+ customers out of service, they could confidently publicize an 800 number for their customers to report problems. News accounts I heard mentioned a figure of about one thousand telephone customers out of service in the same geographic area. I personally was one of the many Bell technicians who worked 14+ hour days in the 10 degreeweather to restore service to those customers affected. Michael W.

Date: 29 Jan 1994 14:38:00 -0500 Organization: Laurentian University, Sudbury, ON, Canada I would like some info on what's involved in connecting to the Internet. At first I thought the only way to connect was through a T1 line, but now I hear you can connect with a 9600 baud line. Someone told me they were connected through their local internet provider. Who are these local internet providers? What are the costs for these lines and monthly fees, etc? Email me or post here. Thanks in advance, James Albert Guitard, Laurentian University 92065034@ramsey.cs.laurentian.ca ------------------------------ From: jmiller@wendy.iac.net (Jim Miller) Subject: Need Panasonic Bag Phone Battery Date: Sat, 29 Jan 94 16:41:32 EST Hi, I am in need of a battery for a Panasonic EB-2501 bag cellular phone. I have checked MCM Electronics, which has a decent selection of replacement batteries, with no success. The battery is part number EB-P0057, 1000 mAH. Are there any good sources (mail-order) for cellular accessories like mobile mounts, through-glass antennas, chargers, and the like, that you would recommend? Your help is very much appreciated!

Proud of their employer, and proud of a job well done under most extraordinary circumstances, a few of the folks there send me news via my fax machine from time to time; they also send email. I like faxes the best under the circumstances since fax machines don't lie and neither do scanners which input the faxed material into the computer. (By the way GTE-droids, its not Steven Lichter, you've managed to get him under control ...). Anyway, my printing of things published as internal communications at the lightbulb factory has gotten *some people* very, very upset and bothered, especially since they can't figure out who is sending me those bulletins. The dude has no answer-back on his fax machine for good reason. :) A fellow from GTE who identified himself as being part of (or responsible for) security for GTE where 'internal documents' were concerned called me on the phone one day and seriously urged me to not print any more of the things that were sent to me 'outside of regular corporate channels'. He said he would ask about adding me to the media mailing list so that I'd receive things from the company on an official basis -- don't tell him I said so, but I think he meant I would be getting the whitewashed versions henceforth and hereafter. Concurrent with asking me in a polite way (I wonder if they will become less polite as time goes on) not to print any more memorandums sent to me by friends of the Digest (and I might add very dedicated, loyal and proud employees of GTE -- yes, there is more than one feeding me), the following statement began appearing on those earthquake reports being distributed: -------------- THE FOLLOWING INFORMATION IS A COMPANY PROPRIETARY STATUS REPORT ON THE CALIFORNIA EARTHQUAKE. ANY DISTRIBUTION OF THIS INFORMATION TO A BROAD EMPLOYEE AUDIENCE (VIA ELECTRONIC MAIL OR PRINTED DISTRIBUTION) OR ANY EXTERNAL DISTRIBUTION (WHETHER MEDIA OR ELECTRONIC BULLETIN BOARD SUCH AS INTERNET OR COMPUSERVE) MUST FIRST BE CLEARED THROUGH APPROPRIATE GTE PUBLIC AFFAIRS CHANNELS. -------------- Yep, the deep-throat even went and sent me stuff with the above message printed at the top of the page. But I'll be Mister Good Guy this time around and *not* print the rest of the memo. Let's see how fast GTE keeps their side of the bargain and adds me to the official list. My fax number is 1-708-329-0572 but email is also okay. By the by, the GTE-droid denied there was fuel all over the floor in the Santa Monica CO after the earthquake. At least he denied it until I read it back to him right from the faxed page where it said there was ... To close this issue of the Digest, George Gilder has written us with a response to Neil Postman's remarks which were printed in these columns a few days ago. I'm always glad when Gilder takes a few minutes out of his schedule to write us; he's one of the best. See the next message ...

Computers do not support centralization; they destroy all top down, centralized and master-slave structures. They disestablish all the hierarchies, monopolies, pyramids and power grids of established industrial society. They give every hacker at his workstation the creative power previously commanded by factory tycoons and the communications power once monopolized by broadcasters. IBM, USSR, EEC, NTT, all these colossal acronyms are collapsing into an alphabet soup because of the power of distributed computing governed by the law of the microcosm, the inexorable tendency of the chip to distribute power and intelligence as the density of electronic components rises by an order of magnitude every five years on a single sliver of sand manufacturable for a couple dollars. It is the masses who are always favored by technology; the medieval era Postman acclaims offered a life expectancy of around 35 years to all but the luckier kings and lords. Postman's notion that the distribution of information somehow eclipses knowledge is nonsense; knowledge and wisdom are always rare, but new technologies make it far easier to distribute it. The meaning of life is always elusive, but computers do nothing to inhibit religion or faith. They do everything to impel economic expansion and opportunity, which is a good even in an era when the culture is largely corrupt, and nowhere so corrupt as in the universities upholding an umphalosceptic intellectualism, combined with a luddite resentment of the real accomp- lishments of our age, which are not alas cultural but scientific and technological. To see worlds in a grain of sand, the dream of Blake, is the achievement of the modern cathedral -- the silicon chip.
