Sorry, you're wrong. The telephone network is designed to work with human voices. As such the equipment multiplexes many conversations onto a single wire. Human conversation has many gaps that the network can use to multiplex other conversations using the same frequency. A modem is on continously, tying up a frequency full-time. Assuming that a wire can handle 100 different conversations at one time, and further assuming that 10 % of the conversations is quiet, that means that with the proper equipment a single wire could handle 110 conversations at the same time. However, you use modems and all of a sudden the network loses some of its excess capacity. I am sure that my numbers are not correct, but the method is valid. I do not support the idea of extra charges for modem usage, and the phone companies' numbers will have to be looked at very carefully, however you cannot deny that modems _do_ take up bandwidth that conversations do not.

There is a form of compression called DSI (and there may be other forms also) that allow this "dead space" to be used. You might put 12 calls on 8 lines and assume the "dead space" would allow you to compress bandwidth this way. I know this is done quite frequently in fully digital private networks, but I don't know how the public networks work and whether they use this type of technology.

Telenet ignored calls, letters, and certified mail. I finally changed my CC account # to stop the bills. Patrick Townson, the moderator of the comp.dcom.telecom newsnet, took my complaint to Dave Purks directly. He replied with a form letter post to the comp.dcom.telecom board, addressed to all. Still never bothered to talk to me, though. This was not good enough, so I sent another complaint through Patrick T. This resulted in a call, the next day, from David Rupp, from Telenet. He has been given the unenviable assignment of watchdog over customer service at Telenet. He was amiable, knew about my problem, and arranged a credit (theoretically, we'll see when I get my statement.) There was no record of my registered letters that he could find. He'll look into it.... I explained that I wasn't the only one in this boat, and asked him to fix that. He replied that he would like everyone with this type of problem, who has not been able to get satisfaction from customer service, to write to him directly, bypassing CS. To do this, send mail to: Telenet Communications Corp, HQ23E, 12490 Sunrise Valley Dr., Reston, VA 22096, Attn: David Rupp. The only way he will find out if CS is screwing up is to hear from you, so write him if CS ignores you!

When I first started there (november 1978) the TWX machine's dial tone came from Pacific Telephone (from the Anaheim Lemon street crossbar). The, one day, it changed!

As the calls would undoubtedly get charged the minimum amount for a "collect" call, dredging for these lost calls could easily be worthwhile. Instead of several human operators handling many calls, a single operator could listen to the few recorded seconds from many calls and tap a "charge for call" button (or type the 'name') when appropriate. Security staff can start by with random sampling, and it could increase to a task to fill operator idle times (or not retiring an operator replaced by the automated service). A permanent record of corrected charged calls, and the legal differences between a phone call and an obvious recording should be useful.

Also, he assumes that there is some inherent, cast-in-stone right to privacy concerning the use of the telephone. I'd like to turn it around. Just because in years past we have *not* had the technology to reveal callers' phone numbers does not mean that failing to do so is the natural order of things. I'm sure that if Caller-ID had been an inherent feature of automatic switching systems from the beginning, this would be a non-issue. The word "Luddite" comes to mind: A person who automatically resists change, particularly technological. I, for one, barely tolerate the lack of Caller-ID service in California only because I recognize that Pac*Bell is too backward to provide it. This, as bad as it is, is at least a legitimate reason for its non-existence. However, if Pac*Bell could provide the service, and it was unavailable simply because some Luddites had decided that people who call me have the right to know my number but I have no right to know theirs, I would be pulling out all the protestation stops. Yes, Mr. Rotenberg covers his ground very well, but unfortunately you have to subscribe to his basic assumptions to be able to agree. I, for one, do not. John Higdon | P. O.

Indeed, I once found (briefly) a seeming Internet-to-attmail gateway -- very soon I had "cease-and desist" mail from its postmaster, with whom (since I hadn't cost him more than 85 cents, in fact) I quickly was able to make peace; shortly thereafter, he had a patch on his mailer rejecting third-party attmail-bound traffic through his machine. Many sites spring to mind -- cbosgd and athq03, among others -- who are no longer even on attmail because of the expense of forwarding in this way, or who -- like uunet, seismo, ihnp4 -- just blankly refuse to forward into attmail except for their own local users. > Yes, it would be nice if there was a gateway.

You can't, okay? You can however make yourself a little switch box that will connect in "triangle-routing" fashion your keyboard to your mainframe's data-in line, your mainframe's data-out line (normally to your CRT) to a modem TxD line, and the modem's RxD line to your CRT, and in this way, on the line with AT&T Mail, you can transfer to your AT&T Mail account, for further processing, anything that reached you from Internet; similarly, by reversing the triangle, you can download from your attmail account and into your mainframe account and thence onwards into the Internet whatever has arrived there.

I am amazed that people put up with such rip-offs, and THEN talk about how bad GTE is. In my GTE area, the technical quality has been excellent since they ripped out the entire CO plant and replace it with ESS about 3 years ago. Since then they have replaced the cable plant in most of the city (they were running out of pairs). And hunting is free. I have my two lines in a circular hunt group, though I'll probably change that some day. (When the voice line is busy, I don't usually want to deal with another voice call untill I get off the first one). Technically, what is the difference between hunting and busy- forwarding ?

Probably not...) For Caller*ID information to be displayed, assuming you have subscribed to Caller*ID and have the Caller*ID box (and therefore your CO is equipped with the appropriate hardware and software), one of the following must be true: 1. The caller must be calling from a phone subtending the same CO you do; 2. The caller must be calling from a phone subtending a CO which is equipped with SS7 (common channel signaling system #7), which is in the same LATA as your CO. (At some time in the future (beyond 1991), when Interexchange Carrier SS7 interconnection is available, add:) 3. The caller must be calling from a phone subtending a CO which is equipped with SS7, run by a telco which has SS7 connectivity with the caller's IC, which has SS7 connectivity at the appropriate tandem switches, and has SS7 connectivity to your telco. Simple, hey? In practical terms: Today, you would get the calling number from calls inside your LATA (in the philly area, generally local calls), from COs which are SS7-connected (not intuitively obvious which are, but generally some reasonably high percentage of "major" COs in the LATA will be SS7-connected before a telco will offer CLASS). You would not get calling number from Pittsburgh, Baltimore, or Boston. At some point in the future -- but not before mid-1991, most likely -- you would start getting some calling number delivery from outside your LATA. There are so many variables involved that I won't even *try* to predict where you would and would not get delivery.... save to say that Pittsburgh would be your best bet (Bell of PA), followed by Baltimore (C&P of Maryland, different telco but part of Bell Atlantic) followed by Boston (different Regional Company -- NYNEX).

You can buy an analog phone that has a little message led that flashes once a second when there is a message. This is in addition to the sudder dial tone. Your old phone can do the job. Put an led in series with a 22K resistor across your phone line. Get the polarity right so that the led lights when the phone is ON HOOK. When you have a message the led will blink off momentarily once a second. It will flash brightly when the phone rings and when you are off hook it will go nearly out. Have fun. PS.

We also have a fiber optic ethernet backbone network whose configuration was chosen to permit easy upgrade to FDDI when such bandwidth is required and when the upgrade is cost effective. The environment is mostly Unix and VMS machines on the ether, running TCP/IP with some DECNet. There is some LAT on local ethernets, but only TCP/IP and DECNet will be supported on the backbone. The backbone is implemented at present with cisco routers and subnets for various faculties and departments. THere are a few IBM hosts that are or will be running TCP/IP, including the server for the library catalog application. The is some confusion here about the utility of ISDN in the short run and in long run. The following questions have arisen: 1. How do we create a gateway between ISDN and TCP/IP so that the following common cases can get access to TCP (and the world): a. Dumb terminals with an rs232 connection to circuit switched d or b channels (i.e., 9.6 kbs or 64kbs). b. Intelligent peronal computers such as msdos and macintosh machines. These machines would ordinarily have ethernet cards and run something like FTP Software's TCP implementation, or NCSA Telnet on the macs. There might be a stray Unix box somewhere (no one wants to run slip). THe ISDN connection is BRI, not PRI. c. Local area networks in buildings which are nt yet connected to the fiber ethernet network. These networks are typically Appletalk or TCP/IP itself, with a few Novell networks here and there. Again, the ISDN connection is BRI, not PRI. Thanks for any information you can offer.

Pressing any of these while on-hook would imply "SP PHONE". o Be able to program "SP PHONE" (or ICM or CO) buttons in the station speed dial memories. The goal is to be able to program a button, DO NOT DISTURB, for example, that would, with a single keystroke, go off-hook (sp phone), dial *7110, wait for the confirmation tone, and go back on hook. o Momentarily drop loop current to a 2500-style station when disconnect is detected. This would allow me to connect my answering machine as an extension without having to wait several seconds for VOX disconnect on incoming messages. o Be able to program ringing phase for each station, so that physically nearby telephones ring simultaneously (subject to max current limitations). o Be able to assign different ringing cadences (selecting from maybe three or four options) to different CO lines so I can tell which is ringing without having to look at, or even have nearby, a proprietary telephone. o (This one takes hardware, obviously:) Decode Caller-ID on CO lines and send it to the LCD displays on the expensive proprietary telephones I've already bought.

Although I tend to disagree with some of the content... and while I was trying to figure out why, I realized that the central theme of Mr. Rotenberg's comments is. "(Calling Number Delivery) compels the disclosure of personal information, without the consent of the caller. This is at the heart of information privacy and the reason that so many civil libertarians and consumer advocates are concerned about the service." Given that, the rest of the arguments tend to flow. There is a basic assumption here that Mr. Rotenburg doesn't address, though: Is a telephone number "personal information"? Or is it corporate information belonging to the telephone company? I don't have an answer, of course (but I smell a Ph.D. thesis...) I will offer some possibilities for discussion, though. What exactly is "personal information"? Name? Blood type? Is there some common thread that distinguishes "personal information" from other types of information? If the telephone company wanted to change your phone number, would you be able to get a restraining order preventing them from doing so? The telephone companies, after all, have changed people's telephone numbers in the past and will continue to do so -- ask anyone whose number used to be 312-NXX-XXXX and is now 708-NXX-XXXX. If a second party can change information, is that information "personal"? I do agree very strongly with Mr. Rotenberg's second recommendation -- involving privacy advocates, public advocates, and so on in the process of defining new services.

If your modem traffic is passing through trunks (not just confined to two local loops served by the same end office) you're going digital. A modem conversation is one continuous scream and definitely (depending on how the signal is modulated/ compressed) takes up more trunk and switch bandwidth than the circuit held by two people who have fallen asleep after phone sex. If, however, your local loop (assumed still analog) is connected to another local loop at the same end office via an analog switch, what you've got is similar to an operator sitting in front of a patchboard - an electrical circuit which doesn't care what it's carrying (you get your 4KHz). Then there's ISDN with digital local loops.... _/**/Sam_Fulcomer sgf@cfm.brown.edu sgf@browncs.bitnet ------------------------------ Date: Tue, 5 Dec 89 13:08:01 CST From: Bernard Rupe Subject: Re: Modems and Phone Rates Organization: Motorola Inc. - Cellular Infrastructure Div., Arlington Hgts, IL In article <1798@accuvax.nwu.edu> jbayer@ispi.com (Jonathan Bayer) writes: >X-Telecom-Digest: Volume 9, Issue 551, message 1 of 11 >Sorry, you're wrong.

Although I haven't been following this subject consistently, I think I can shed some light on the situation. Voice calls in today's network are indeed restricted to 3400 Hz. These calls are sampled at 8 kHz and converted to a digital rate of 64 Kb/s. These 64 Kb/s channels are then multiplexed and sent into the telephone network. Today's technology does not take advantage of any silent passages in conversation (although it could be done, it would be very expensive). Modem data is converted into the same 64 Kb/s and is multiplexed into the telephone network just like a voice call (otherwise, how could you use a regular phone line for a modem call?). The result, then, is that a modem call and a voice call take up exactly the same bandwidth in the telephone network.

There are two major problems with this. Long distance companies rarely do this anymore (it was too disconcerting to the customers) and local telcos *NEVER* do this between local offices. And remember, it's the local telcos that want to put the extra charges onto modem users. The drift has been lost here. Every justification for discerning between modems and the human voice would apply to LD carriers, not the metallic circuit that runs between your PC and your local central office. You already pay for long distance; is someone suggesting that modem calls should be charged at a higher rate? But the original question concerned whether lines used for modems should have higher *local* charges applied across the board. John Higdon | P. O.

I have 2 phone lines, one for voice, and one for modem. I run a bbs on the modem line, and use it for outgoing calls to other bbs's, locally, and long distance. I am also president of a users' group which runs another bbs, which I call often. The problem is that I have absolutely no (transmission) problem calling any other bbs, local, or l/d. No user of my bbs ever has problems, including calls from the same modem the user group bbs uses. The only problem is when I call out from my modem to the user group bbs modem, on my modem line. I get lots of } echoed in response to my outgoing characters. If I switch my modem to the "voice" line, I have perfect transmission to the user group bbs. I have tried several modems at my end - I currently have a Supra 2400 on it. I have tried a Promethius 1200, which is the same modem as the user group uses. The problem persists with both of my modems. The phone company did come out and fix a grounding problem, and even changed the line to another pair, and the line tests 100% quiet. They are unable to do anything else. Every combination of my modem to anyone else's seems to be perfect in both directions, except for the one bbs, that bbs modem can call mine ok, and using my voice line to call theirs is successful, which seems to rule out interexchange trunk problems, too. Can anyone give me any insight as to how to cure the problem (other than using the voice line?). Bruce Nelson ...!rochester!kodak!nelson ------------------------------ From: "John H."

My company's name is The People's Computer Company. For a while after we got an office, DA was giving out our number as the PeopleExpress Airlines reservation number. Someone would ask for Peoples Express, the DA would type in Peoples... and come up with our number and give it out. We kept track of the number of times we had to give out the correct PeopleExpress phone number, and eventually billed New England Telephone for using us to give out the PeopleExpress phone number.

Sawyer) ---------------------------------------------------------------------- Date: Tue, 5 Dec 89 13:39:47 EST From: "Mark B. Cohen" Subject: Various Questions and Observations Recent, and some not so recent, articles in the Digest have brought a few questions and observations to mind. Old CO switches: I live in a town that only recently upgraded from pulse-only to electronic switching. [As a side note, kudos to New England Telephone for no noticable problems during the actual change.] My parents live a town that is also pulse-only (with no known plans for change....) With the old switch here in 508-865, intra-exchange calls could be dialed using 5-XXXX. At my parents residence, in 413-229, a similar intra-exchange call is dialed using only XXXX. Dialing the five digits would connect to 9XXX and drop the final digit. Is this difference significant, or just a feature from different switch manufacturers? Alternate LD from pay phones: Recently, I stopped at a pay phone in Brewster, NY (914-???) to place an interstate call using my NETel/AT&T calling card. The phone was clearly labelled with "Calls outside the 914 area code are handled by AT&T Long Distance Service". Dialing 0+number produced the expected 'gong' tone, after which I entered my card number. The response was a recording: "Thank you for using First Fone." After waiting for about 5 seconds (for a connection that is normally almost instantaneous) I closed the connection, and redialed using 10288+. This time, the connection was effectively instantaneous, with the traditional AT&T recording. In the past, I've also gotten a Sprint attachment to my NETel bill for an interstate calling card call. Two questions on this issue: First, is there any form of legislation that requires the _correct_ LD carrier to be displayed on a pay telephone? Second, can carriers such as Sprint or FirstFone utilize another carriers validation code? My understanding is that one must establish an account with an alternate carrier and receive a carrier-specific validation code. Misuse of local DA? A chain of diet centers in the MetroBoston area has been using a commercial that in my estimation is a blatant misuse of DA. At the close of the commercial, instead of an expected list of locations or a toll-free number, etc. etc., the image ends with the text "Call 411 today." Ironically enough, I first noticed this commercial shortly after the start of the strike against NETel. I called the NETel business office and mentioned the existence of the commercial. Their response was that if I wanted to file a formal complaint they could investigate it. I told them, thanks anyway, but I just thought they should know about it. NPA splits: I've now lived through two splits, one in each part of the affected area. During the 212/718 split, I had a job similar to Patrick's: I was a collector for second and third-party payments for a large hospital in Manhattan. For the 617/508 split, I moved less than two months after the split, so my number effectively changed twice in six weeks. I was never aware of any reported difficulty during either split. Toll-free numbers: A local radio station recently ran a large campaign for giving away thousands of dollars. (Don't they all? :) The station's studio is located in Worcester. Their business and request lines are local Worcester numbers. For this campaign, the number they advertised was 931-1045, which they claim is a toll-free call. (Non-coincidentally, their frequency is 104.5 MHz.) Calls to 931-1045 require a leading 1 from 508-865, which is local to Worcester. A check of the phone book showed an entry for 617-931 in Boston, and no entry for 508-931. 617-931-1045 is invalid. Is it possible to have an intra-NPA toll-free call without the leading 800? (I've never been able to get anything other than a busy, fast-busy, or a circuits busy recording when calling, so I don't have a record of a completed call.) Old telco equipment: In the basement of my parents home, I recently discovered some form of old telco battery. There was a case somewhat secreted among the floor joists, with a small cable (disconnected) running to it. The case itself it roughtly the size and shape of a large binocular case. Within the case are what appear to be two large dry cells. Each of them is cylindrical, roughly 8 inches high and 3 inches in diameter. They both have two screw-top terminals on the upper face. The upper and lower faces appear to be cardboard, and the wrapper is brown (now anyway) paper with the words (from memory) "Bell Telephone Property, Nov. 1929" (Date is approximate, I haven't looked in while. It's definitly the 1920's though.) From my understanding of the history of the house, it was built in the late 20's. Until 10 years ago, the house was at the end of the line for both telephone and electric service. (What's cable TV? :) So what are these things? Everything I've read on the history of telephony indicates power supplies were centralized. It also doesn't make sense to me to place expendables in a location not easily accessed. One final question, not directly related to telephony: Is the large population of people on the network with technical telephony knowledge the result of UNIX(tm) originally having been a Bell Labs product?

Here's the text (there is no copyright on the ad): [Big headline] Can you imagine living in a country that limits the flow of information to its students? [Big headline] You do. [Bold italic] If Naason Sanchez lived in Great Britain, his telephone line could connect him to a computerized information service that would help him learn to solve math problems and answer geography questions in an instant. But Naason lives in Los Angeles, California -- in the United States of America -- and he isn't that lucky. Here in America, the Bell telephone companies aren't allowed to work closely with educators to create and offer information services like these that can help students learn. Or for that matter, provide many other services that could improve the lives of American citizens in ways people in other countries take for granted. Nor are the Bell companies allowed to design and produce equipment which could make these services easier to use. [Headline] Why is the U.S. behind? In 1984, an agreement between AT&T and the U.S. Justice Department split up the nationwide Bell system, forming Pacific Telesis and six other regional holding companies. At that time, very narrow limits were imposed on the services that their phone company subsidiaries, like Pacific Bell, could offer. Today, students in many other countries can use their phone systems to reach special computerized tutoring services, or they can access data bases that can help them do the research necessary to complete their homework assignments. Meanwhile, here in America, it's a different story. These services are available, but only in limited locations, and at high cost. If the Bell companies could develop and provide these services, along with many others that people in other countries take for granted, they would become more widely available, and growth of this market would encourage more information providers to enter it. [Headline] There _is_ something you can do. Legislation that would lift restrictions on Pacific Bell has already been introduced in the U.S. Congress. But it's not too late for you to learn more about this issue, and help us do something about it. The education of Naason Sanchez and millions of other American kids is too important to put on hold. [Boxed] STOP PUTTING AMERICA ON HOLD [Logo of telephone handset with a pair of hands] For further information, call Pacific Telesis Group. 1-800-776-1636. [My comments: 1. I sincerely doubt that Pacific Telesis expects to make much money off of education-only information services. I would expect them to quickly take a back seat to more lucrative commercial services. 2. How many countries have telco-owned information services? Britain, France, and who else? 3. Lifting restrictions may be a bit more general than the ad implies. I plan to call to get the further information. 4.

I came across a little gadget that is supposed to do just that in a catalog from a company called "The Fordham-Scope Catalog". Below is the description as it reads in the catalog: Answering Machine MESSAGE STOPPER! Stop your answering machine mesage when you pick up any phone in the house. Your answering machine will automatically reset while you speak. Simply plug the Message Stopper into the telephone wall jack. Then connect your answering machine and telephone into their respective slots. The Message Stopper can also be used to prevent others from interrupting or overhearing your phone conversation. Message Stopper model #MS-2. $7.95 each 2 for $15.00 Physically, it looks like one of those two-for-one adapters that give you two plugs for one, plus a green and red led (one for each jack) The phone number for the company is 800-645-9518 (800-832-1446 in N.Y.)

Date: 5 Dec 89 15:25:11 EST (Tue) From: "Paul S. Sawyer" [Please note that any comments following are my personal opinions. I make no policy for, nor do I speak for UNH. I run the UNIX System, not the switch. We are familiar with ACUS only as users of software which they own.] Many persons, apparently students, have written lately to complain about various campus phone services. Recently Paul Selig brought up a few points to which I would like to add, to help show the position that we are in as service providers.... Since Divestiture, the local telco may not want to bother with serving your dorm room, unless it is already wired. Sometimes the telco does not even have wires to the building. It is the property owner's responsibility to provide the means (space in existing conduits or on poles, or easements and in some cases costs to install conduits or poles) to serve those buildings. Some colleges/universities do not wish to do this. Some opt to let an outside agent handle this. UNH is wiring buildings as possible, trying to eventually provide service for all campus residents. If we had to act as a public utility, we would have to do this all at once and so might not do it at all, since our main job is to provide business telecommunications for staff users. In most cases, we are making use of existing equipment and capacities which are not otherwise fully used after business hours. Keeping track of even a small number of students as customers is quite different from keeping track of departmental customers, especially with no additional staff. Outside agencies such as ACUS can seem attractive when they can act as turnkey service providers. Although some larger or more fortunate institutions have central office type switches and answer supervision, we and many others do not, and it would not be cost effective to implement soon (so they tell me). TSPS or similar service which someone mentioned as available to hotels, etc., was refused to us because we ARE NOT A HOTEL under the tariff, said the telco.... We already process outside toll tapes which include collect calls, etc., so we do not charge extra for such calls, but if you attempt a fraudulent call or make an operator assisted call which gets billed to other than your own number, we have to research it, and "Bill'em, Danno" an extra $2.00. We do this whether you are student or staff, since it is preventable. We do not knowingly block access to any long distance company that is normally accessable, although our direct dial prices should be lower than those with credit card or operator surcharges. We do not charge for 1-800- 950- or local calls. Our business office treats our fees as normal student expenses, so we do not need to charge a deposit or cut you off at a line of credit. Some institutions do not want to collect telephone bills. I agree that "Colleges and universities can only get away with this crap if their students and staff let them!" [eravin@dasys1.UUCP], as ACUS and other third parties all make some arrangement with some agent of any institution they serve, one or more of President, VP, Dean of Students, Telecom Office, Buildings and Grounds, Housing Office, probably Trustees and/or State Board of Regents, etc, ad infinitum, ad nauseum. Each institution has different people making different arrangements for different services, and differs in responsiveness to student needs. As telephone service providers at UNH, we try to be responsive, we welcome complaints, and we even give credits! (sometimes... B-) But you don't call the public utilities commission because the lights in your dorm flicker every time you make popcorn... so work with whoever runs these things on YOUR campus and maybe you can get somewhere!

The concept here is that any signal which is beamed into YOUR airspace belongs to you, and you can do with it as you please subject to certain restrictions for reasons of national security. The concept here is "personal use" of material which is intentionally or unintentionally sent into your property: Just as with broadcast TV, you can (watch / videotape) to your heart's content, as long as the material is for your own personal use. You cannot sell, or in many cases give away, such information if it is "obviously" of a restricted / copyrighted nature. Under the Act, if you are to receive a transmission of a "secret" nature, you are obliged not to divulge the information to anyone (even for free), but may listen to it yourself. There are three recent examples of subsequent laws which appear to violate the Act: (1) States which ban radar detectors, which are effectively radio receivers. The Communications Act of 1934 is frequently used in defense of radar detectors (although your rights for receiving signals while MOBILE, on public property, are not clear). (2) Descrambling satellite transmissionswas made illegal not too long ago. This is another case of a (presumably contestable) situation where you are prohibited from using, even for your own personal reasons, information beamed into your house without your consent. (3) Protection for cellular telephones. I think that half the reason for the Communications Act of 1934 is one that we are seeing right here: If, by voluntarily transmitting a low-power signal on an authorized channel, in such a manner that the signal invades my neighbor's property, can I now seek to make it illegal for my neighbor to listen to that frequency ever again? Is the liability my NEIGHBOR'S (for listening), or MINE (for beaming the signal into his house)? This is what the Act seeks to resolve: that airwaves are public in nature, and cannot be monopolized by people who intend to use the resource as their own private communications device. If I wanted my baby's noises to be secure from prying ears, I could have easily trotted down to Radio Shack and purchased a wired(!) intercom that doesn't pollute the airwaves, or (what a concept!) put the baby where I can hear it without electronic assistance. (A bit more reliable, don't you think?) If I'm really bent on wireless intercoms inside my home, I should either accept the fact that I am voluntarily BROADCASTING, or at least take measures on my own to see that the transmissions do not leave my house. Most manufacturers of cordless phones (even some cellular phones), baby monitors, and other "Part 49" gizmos DO alert you to the fact that wireless communications defy privacy. This is not merely our law, but a law of nature as well; to legislate otherwise will bring us nothing but headaches.

Date: 4 Dec 89 20:45:54 GMT Reply-To: Russell McFatter Organization: Alliant Computer Systems, Littleton, MA While debating the question of how much load modem users actually create, I think that we've been missing a more important issue. Let me ask you the question: Why do you suppose the phone companies are really in favor of modem surcharges?? Does anyone really believe that this is out of a well-meaning intent to avoid the kind of dial-network overload that we only ever see on certain holiday afternoons and during major disasters? At least in THIS area, NYNEX seems to provide their own answer-- in terms of incredibly expensive, prime-time regional television advertisements telling you that you should be using the phone MORE. Keep in touch with everyone you know! Give 'em a call right now! This is backed by more TV and radio ads with themes such as "...you should have FAXed it!" and "How could you have known that the store was closed?? You should have called!!". Print ads do much of the same. Is this the behavior you would expect of a utility that is short of resources and wants to conserve them? (Contrast with an electric utility, which nowadays as they near peak capacity would never run an ad such as "Turn it way down and keep COOL this summer... with enjoyable central air conditioning"!!) Unfortunately, the BOC's tend to complain about the cost of providing some service until such a time as the rate commission gives in to the increase... and then they follow up with a marketing frenzy for the same service. New England Telephone has complained for years about not being allowed to charge for directory assistance, and they keep reminding us how it costs them "millions" of dollars. A friend of mine from New Mexico tells me that the story was the same there, but in his area a 60-cent-per-call charge was approved, and now they run advertisements telling you how much better it is to use directory assistance than to actually look up the numbers yourself. I suspect the same would be true for modem surcharges... "Don't sit there waiting for YOUR news... Poll your news host every five minutes!!" "Spend a good long time with your friendly local bulletin board service... Only $8.60 an hour! (based on a ten-hour call at lowest off-peak rates with maximum quantity discount and other provisions for calls in your local service area for a limited time only with rebate at participating locations.) I suppose that part of the basis of our (still a monopoly) phone network is to charge you something for (virtually) nothing: Tone service (they could actually save a lot of money by getting everyone to switch to tone and eliminate pulse dial)... Custom calling services (that are all handled at no extra expense by the central office's computer)... and the ubiquitous $8-$25 "service order charge" that represents 60 seconds that an service representative takes to punch your order for these into a computer. Haven't we had enough of this already?

Even though I think it will happen earlier than 1994, I agree with Mr. Lewis. And, yes indeed, "the audio leased line department will go out of business in a hurry!" When a user can dial up a full T1 circuit for 10 minutes *and be billed for only 10 minutes use*, it's going to be hard to justify leasing a 19.2 kb/s connection 24 hours a day, 7 days a week.

Valid, perhaps. Used, no. (OK, before someone jumps on me and starts throwing "statistical TDM" around... not used by the public switched telephone network in any major applications.) > I do not support the idea of extra charges for modem usage, and the > phone companies' numbers will have to be looked at very carefully, OK, let's clarify some terms. A two-way voice conversation includes energy in the frequency band 20-20000 kHz. The majority of this energy is below 4000 Hz. An intelligible voice conversation, therefore, can be considered to include energy in the frequency band 300-3300 Hz. It also includes a large amount of dead air. A telephone voice channel is capable of carrying energy in a frequency band from about 300 to about 3300 Hz. This channel is constantly available, end to end, to the user. Regardless of the fact that no energy may be carried at a given point in time, the capacity is immediately, fully, directly available to the end user at any given point in time, and is not used by the network for any other purpose. This is true whether you're talking an analog loop, an analog trunk, a time-division multiplexed digital trunk (on any medium), an ISDN loop... doesn't matter. The 3000Hz of capacity is not used by the network for any other purpose. Therefore, it matters not whether that 3000Hz of capacity is 100% utilized, 90% utilized, or 10% utilized -- the resources are fully available to the end user, and you should not charge the end user more because he's able to make more efficient use of the channel provided him. > however you cannot deny that modems _do_ take up bandwidth that > conversations do not. Yes, I can. I can't deny that modems make more efficient use of the available bandwidth -- but I certainly can deny that modems "take up bandwidth conversations do not". A modem, be it a 300bps Bell 103, a 1200 bps Bell 212a, or a 9600 bps V.32, uses 3000 Hz of bandwidth. Period. A conversation uses 3000 Hz of bandwidth. Period.

Almost right, it works like this: There are several providers of transatlantic service using both cable (copper & fiber) and satellite links. British Telecom International (BTI) routes calls by some algorythmn known only to themselves and you may get any one of the above and any one of 3 or 4 long distance providers on the US end of the link. There is a magic code that you can dial after the get out code (010) country code (1) and before the areacode-prefix-number.

In my experience, with Sprint and MCI at least, you can use your local BOC calling card (which is usually the same number as your AT&T card) for 10xxx+0+ calls, but FONcard or MCI card numbers will not work. I believe that the BOC does the calling card validation and handles the billing in this case. If you have any volume discounts with these carriers, your FONcard or MCI card calls would contribute to them, but using your BOC card probably wouldn't. (You probably wouldn't get your MCI "Around Town" discount either.) This is mostly speculation, so take it for what it's worth, but try using 10777-0-NPA-NXX-XXXX and using your local operating company card number. (C&P Telephone recently reissued fancier-looking "IQ Cards" to their customers to replace the old "Bell Atlantic cards". The new cards actually contain the last 4 digits, and the glossy brochure accompanying them explained [in marketing-ese] that default 0+ carriers can be now individually assigned to pay phones and that you can use their card regardless of the default carrier, or with specific carriers using those carriers' access codes.)

I have no problem with Pac*Bell keeping their 1As around for awhile. They can provide almost any service currently available (with help from an adjunct, they can provide *any* service) and they do it in a grand style when compared to DMS or 5ESS. 1AESS has always had superior feature implementation, IMHO.

And in my case, I am sick of this 1ESS that can't even do "cancel call forwarding". My CO has four prefixes of 1ESS (marginal, at best) and eight (8) prefixes of crossbar.

If it was GTE, that would all be somewhat iffy. So I'm supposed to count my blessings, and be thankful that I have Pac*Bell. Well, I guess crossbar is better than directorized step-by-step.

I found out the hard way how important the "twisted pair" is: I once wired a building for phone using two "twisted-3" cables. My thought was that I wanted a total of six conductors, for up to three lines. What I really needed was a 3-pair equivalent, but at the time I didn't understand the "pair" concept. So I used one conductor from each cable to form the three pairs: {red A & red B}, {white A & white B}, {black A & black B}, where A is one twisted-3 cable and B is the other. This worked fine for the first line, but I had all the six conductor jacks installed before I connected the second line. That's when the trouble started. You could hear the conversations on the second line almost as well as you could hear your own conversation on the first, and vice-versa. Apparently, the twisting of the pair effectively sheilds it from the electromagnetic radiation of the other pairs. By not using any of the existing two twisted pairs but instead using separate twists for one wire of each line, I had created the worst-case condition, effectively creating a transformer which coupled the two lines together. The problem was especially bad because, at the time, my parents were going through a divorce and each had a separate phone line and they were sorta in separate buildings which shared some wiring. They didn't appreciate being forced to listen to each others' conversations. Anyway, if you try to use the spare conductor from your cable and the spare conductor from someone else's, you may end up with a three-way party line. It might work for only 25 feet, but I wouldn't bet on it. >I've been told there is a way to use some kind of bridge circuit at >each end of a 3-conductor wire to enable two phone lines to be run >over the wire. I once had a device on the outside of my house that allowed two different lines to somehow use the same pair to the phone company. Telco installed it and there must have been a device at the CO to run it. This was mentioned in passing here in the digest about a month ago. I'm not sure if you could convince telco to install one or not.

The word "Luddite" >comes to mind: A person who automatically resists change, particularly >technological. Well, Luddite may come to your mind but personal privacy rights come to mine. I am incensed that my personal privacy rights have been eroded both by government and by greedy private companies. I'll give you an example. Have you ever pulled a credit report on yourself? If you are at all affluent and/or have had many credit transactions, the personal information the credit databanks maintain on you is a disturbingly accurate reflection of your personal lifestyle. That is disturbing enough but what is worse is that almost anybody that wants access to it can have it. The law says that the credit bureaus must keep a record of who accesses your credit data and must provide it to you on request. In my record, there are literally dozens of inquiries from companies I've never heard of nor done business with. I'm sure that some of these companies were prowling for likely candidates to send free credit card applications to. Others were most likely building profiles for people to inflict telemarketers onto. I terribly resent either use. Still another, much more insidious use is by the IRS. They collect data on lifestyle from this and other databanks, such as mailing lists so that they can impute an income from lifestyle in the event they think you pay too few taxes. I am personally very vunerable to this type attack. By virtue of skillful trading, purchasing and craftsmanship, I live an apparent lifestyle several multiples of my actual income. And yet the IRS could use this very personal information to screw me if they so chose. What I buy, where I go and who I call are strictly MY PERSONAL BUSINESS and no one elses. Particularly those slimebags who are most likely to use such a service - the telemarketers and the government. More than adequate means already exist to trap prank and obscene calls. The only motive that can be assigned to wanting to personally know the ID of a prankster likely looks somewhat like vigilanteism. I'll give you another example of EXISTING caller ID, or as traditionally known, ANI. I've posted before about the sleeze phone company I wrote switch software for. They had feature group D lines which provided among other things, ANI. ANI was needed for billing but they went further. They collected calling statistics by caller and built and sold mailing list names. While it may be legal, it sure is not right. Dammit, my phone exists for MY and my family's convenience and use. No stranger has any more right to invade my privacy electronically than they do barging through my front door. Not answering the phone is NOT an answer. Aside from being driven from a service I pay for, tragedy can happen by ignoring emergency calls. I found out the hard way when I was a teenager. I got to spend the night in jail on a bum bust because my parents were not answering the phone that night. That we later had that cop's ass handed to us on a silver platter was no consolation for having to spend a hellish night in a city jail. I insist, no, I demand that a ring on the phone is either someone I want to talk to or is an emergency. All caller ID will do is allow slime to discover my phone number more readily. Hmm, instead of getting mad, perhaps I should take advantage of the entraprenural opportunity. Hey guys, how do you think a commercial automatic redialing service would fly. You know, you dial an access number to get a dial tone and your call is routed out over the service's line. You think that this service coupled with an iron-clad contract to never collect or release calling information would fly? I do. John De Armond, WD4OQC | The Fano Factor - Radiation Systems, Inc.

When off hook, the voltage drops to something less than 8-9 volts. Ringing is accomplished by superimposing a nominal 86v rms on the -52v ring-tip voltage. An indicating device that turned on at something greater than 52v would accomplish the task, if it could be kept on by an external power source or by the 52v on hook voltage, the latter requiring very low current draw to avoid appearing off hook. As I recall, a device that can do this is the old NE-2 neon bulb. It requires something over 80? volts to turn on, but can be kept lit by well under 1 ma. The bulb, in series with a 100k resistor should be put in series with a diode good for at least 200v. Put about a 2 micro farad cap across the resistor and lamp part of the circuit. Hang the whole thing across tip and ring with the cathode end of the diode hooked to ring. If the lamp is so sensitive as to light with just the 52v, a 100-200k resistor across the lamp should solve the problem. The diode and cap are in the circuit to keep the positive cycle of the ringing voltage and short interruptions of the 52v from extinguishing the lamp. Taking a phone off hook should automatically extinguish the lamp by interrupting the -52v long enough for the cap to discharge. As I said, I have yet to build this, but it should work. It may be subject to some falsing due to lightening, etc. Also, it should be checked for immunity to 'dial tap'. It will indicate an incoming call attempt, but not whether there is voice mail, of course. (The usual disclaimers)**2 and do be careful, a telephone line can bite like a light socket...remember the apocryphal dog. *************************************************************** * John McHarry (703)883-6100 M21198@MWVM.MITRE.ORG * *************************************************************** ------------------------------ From: toddi@gtisqr.UUCP (Todd Inch) Subject: Need a Light to Indicate Phone *Has Rung* (Not *is Ringing*) Date: 6 Dec 89 18:46:41 GMT Reply-To: toddi@gtisqr.UUCP (Todd Inch) Organization: Global Technology International, Inc. I want to reply to the person who wanted a light to tell him if the phone rang (and therefore he probably has voice mail) while he was away. (Sorry, I lost the original article, please forgive my vague reference.) About a week ago I submitted an article on how to make your phone bell into a ringer. If you do that, or use some other relay-type device, it should be easy to make the lamp stay on with the following circuit. Get a relay which will operate on the same voltage as the lamp you want to power. A common normally-open single-pole single-throw type will probably do (see note at end.) Connect the contacts of the ringer-relay (operated by the phone ringing), the power supply (or possibly battery if you use an LED), and the coil of the new relay in a series circuit. Now the first relay will operate the second relay when the phone rings. Now connect the contacts of the second relay across (in parallel with) the contacts of the first relay. This allows the second relay to "turn itself on" and the ringer-relay can also still turn it on. When a pulse through the ringer-relay operates the second relay, the second relay will keep itself on after the pulses have stopped. This is a simple latch which I've also used for burgalar alarms. Connect the lamp in parallel with the coil of the second relay so it is also turned on and kept on. Install a normally closed (normally "on") switch in series with the power to the circuit (or just an on-off power switch.) This will reset the second relay and lamp by momentarily disconnecting the power. It may be necessary to add a diode (rated between 1 and 15 amp and at least twice whatever voltage you're using) in parallel with the second relay coil and the lamp. Be sure the Cathode (striped end) is connected to the Positive side of the coil and the Anode is connected to the Negative side, which is backwards from the way they are usually connected. This will effectively stretch the pulses by using the coil's inductance to keep its current flowing after the pulses have stopped. This is assuming you're using DC power. If you do have a second pair of contacts in the relay, I'd use those for the lamp circuit, disconnecting the lamp from the relay coil. This may be necessary if the lamp draws lots of current. If you use an LED (light emitting diode) with a series 220 ohm to 2K ohm resistor (depending on the voltage) as the indicator lamp, you shouldn't need the diode across the coil and you won't need to worry about the lamp current draw. Also - regarding my previous suggestion for turning a WECO-type bell into a ringer-relay, you MAY be able to place the reed switch in the right spot on the frame or near the magnet or somewhere so that the ringer is still intact (and therefore rings) but also operates the reed switch, although I haven't tried it. The switch may provide pulses which are too short if the magnetic field at that location is too weak. I hope I haven't made this sound too complicated, it really isn't, but let me know if you want more info. Hope this helps.

The following questions have arisen: There was here, too. In fact there was a sometimes amusing presentation at the MIT Communications forum a couple of years ago, after both Harvard and MIT had jointly and independantly made their decisions, where the "responsible" parties from each organization (along with some others) talked about ISDN. As I recall the appropriate paraphrase from both the MIT and Harvard presentations on why they included ISDN in the purchase was, "It's the new telecom buzz-word. If we don't include it and it turns out to be a winner, they'll have our heads for getting stuck behind the times. If we do include it and it turns out to be a lemon, we can always blame it on the Telco...they over-stated its capabilities." Nobody there had any detailed concrete plans of even a single specific use to be made, but there was lots of fluff and smoke. I believe that state persisted even unto the actual cutover at MIT. (In fact the smoke persisted a little after cutover. :-) Harvard's probably just in that same boat. > 1.

Dumb terminals with an rs232 connection to circuit switched > d or b channels (i.e., 9.6 kbs or 64kbs) I'm not sure what you mean here, several points come to mind that you might be asking about. First, the connection (at 19.2kbps) between the dumb terminal on my desk and the ISDN is a standard DB25 on the back of this here AT&T 7506 phone. It even offers you the option of a semi-rasonable command interpreter or Hayes command set (but I guess Hayes is (tm) since the word does not seem to appear in the manual at all, I think they refer to it as "the industry standard AT command set", shades of Strowger and Step-by-Step). The second thing you might be trying to ask is for the case of someone without an actual ISDN connection in the office (i.e. POTS). These people can hook up any kind of modem to the line (they have a standard RJ-11) and call a bank of modems which gives them that same interface (at 300, 1200, or 2400 bps) preset to command interpreter (it's just some dedicated, no voice, connections with the same circuits and software as my phone). The third possibility is you were asking how people outside get connected to my machine if I put it on the ISDN. They can call a number (assigned seperately by telecom) which the 5ESS routes through that same modem bank, but then automatically connects through to my digital number. These three are all in service and in regular use on the MIT switch. > b. intelligent personal computers such as msdos and macintosh > machines.

The best use of ISDN here would probably be to simulate 64kbps leased lines and connect with some standard routers or bridges. You don't get full bandwidth, but with Appletalk at the end do you really care? If you do, pay to get the fiber. I thought Harvard was doing the same thing as MIT. I think we pulled an order of magnitude more fiber than the ESS and Network required together and distributed it to many more places. The cost of the fiber was small compared to the other costs of the installation and the labor to pull N rather than 1 is negligible. Once the fiber is lying there in the dark it doesn't cost a lot to run your photons through it :-). > Thanks for any information you can offer. You're welcome, but you didn't ask about the two most interesting areas (one of which MIT has in place and one of which is "under discussion"), so I'll get to them here. It's probably the case that you meant one of the above to include this and I just misinterpreted it, but I re-read them and I still don't see it. First, given the above, my terminal can reach all over campus at 19.2kbps. So what do I do? Everyone of interest is on the TCP/IP network (this is by definition, my job is managing TCP/IP networks :-) and they're not going to rush out and buy ISDN cards or X.25 software just so I can reach them. The answer is a box from Cisco (the one we use, other manufacturers also do this) with an X.25 connection at 64kbps on one side and an Ethernet connection on the other that knows how to translate between the respective terminal protocols and deal with terminals in general. You call it Pad.MIT.Edu, the MIT PAD. It's just like any other X.25 PAD except that rather than real terminal lines they're virtual using standard TCP/IP networking. Now, while I wait for all the random machines to put in something, I can always call PAD and connect over the network. Note that this system also works in reverse. If someone hooks up with an X.25 host connection designed to be called from a PAD, I can network from my workstation and use commands on Pad to set up X.25 calls. Second, can the 5ESS be used to provide an X.25 subnet to run TCP/IP over? This is the one that's "under discussion". I think the answer is "yes, but why?" I think what's going to happen here -- at least in the foreseeable future -- is that the ESS will be used for "leased line" type services to a few outlying spots, but that no general TCP/IP subnet service. ** * * * * * * * * * * * * * ** Gee, this turned out to be a lot more than I started out to say.

I envisage the appearance of "hi-fi" telephones capable of using this service. Voice would be clearer and music could be carried (with fidelity equivalent to that of a.m. radio). Further, digital technology could enable superior echo cancelling allowing speakerphone use without the "in-a-tomb" effect. Clearly, the new phones would have to be compatible with POTS phones, but Q.931 and SS7 know enough for the service to be negotiated automatically on call set-up. Such phones might become the next great consumer electronics fad, following compact discs and cellular phones. Once people heard the higher quality, they might feel they had to have one, to keep up with their yuppie friends. Any comments? From those who know how the technology is progressing? From potential owners? Oh yes, if these things caught on, they would drive the market for ISDN lines to residential as well as business premises. Just what the local carriers need!

You are wrong about this NEVER working, I had such an installation in service for many years with a run of 4 floors vertical plus some horizontal distance. I used this "extra" line for 212-style dialup data and had fewer problems than any other line I've used with 212 modems. However, a warning (somewhat moderated) is still in order. This "kludge" was done only on the fifth "installation" trip---the first to feature a repeat performer, by the way. On several of the earlier trips many different options were explored, including fire-rated drop cable through an interior "well" in the building and many others. I had talked with the installation and repair supervisor literally dozens of times (we were getting to be good buddies, too bad he's not there any more :-). After all this and another while on this call scouting more possibilities, the three of us decided that the only way that could possibly work was to use my "third wire" and the "third wire" from either the apartment above or below me, we knocked on doors and one of the neighbors was home. I got it installed this way with the implied agreement between me and the supervisor that I wouldn't complain if it was "noisy" (I actually got the impression that he attached a notation of "Contact " for all reports concerning this line before any action). It turned out to be a perfectly fine connection, never a single problem with errors. I would caution however that it really shouldn't have worked, as John points out. In fact I was somewhat agast at it actually being BETTER than the original line had been, I'd expected to need to use the original to get data connections at all and start telling all my callers to use the other phone. We only got to this after exploring MANY other options with the landord and the phone company. I recommend exploring ALL other options first. The phone company was ready to declare it "uninstallable" without this, in fact if I hadn't shown such a wide knowledge of TPC during all the previous dealings with installers and the supervisor they probably wouldn't even have suggested it. I forget why subscriber carrier wasn't an option in my case, but it was brought up. If possible, I would guess this has a better likelihood of working than picking two random wires as a "pair". ------------------------------ From: Lars J Poulsen Subject: GTE vs Pac*Bell (Was: How Do I Rotary?)

I pay $23.50/month for two lines, one tone service with 1+ provided by ATT, and one which is supposed to be pulse-only, with 1+ dialing disabled. The two lines busy-forward to each other. This includes unlimited local calling (but not 6% sales tax). I have considered replacing the second line with a 3002 leased circuit to my place of work (my wife works there too); GTE offered at no extra cost to make the line end-to-end metallic. The distance is 3.2 miles (served by same CO) and I think I could run 56kbps on that circuit. The main reason I'm not doing it, is that I'd have to pay for a terminal server port card on the receiving end (system manager says "all ports are taken"). The cost of such a leased line would be about $150 to install and $23.50/month. I find these rates very reasonable. Especially when I read in TELECOM Digest about people that pay over $35/month for a single residential line. And I have no desire to get CommStar. I'd MUCH rather install a KX-308. I have: - one phone in the kitchen - one cordless in the master bedroom - one more in the master bedroom because my wife hates the sound quality on the cordless (Radio Shack alarm clock radio phone combo). - one phone in my study connected to the main number - one phone in the study connected to the modem line - two modems (one on each line) - an answering machine serving both lines With a Centrex service I'd have to have at least 6 lines to get what I want. That's 4 more than I have now. Even where GTE offers measured service, this would be at least $40/month. That would buy me a PBX in a year. / Lars Poulsen (800) 222-7308 or (805) 963-9431 ext 358 ACC Customer Service Affiliation stated for identification only My employer probably would not agree if he knew what I said !! ------------------------------ From: Alain Arnaud Subject: AT&T System 2000 Inquiry Date: 7 Dec 89 15:13:34 GMT Organization: AT&T Bell Laboratories I have seen ads for the ATT System 2000 master phone for $200 and for the slaves for $150.

When the news reached the mainland a few minutes after the attack on Pearl Harbor (it was at 7:30 AM Hawaii Time; 12:30 PM EST), *everyone* jumped on the phone to tell their neighbors. In those days of mostly manual telephone service, with well-trained operators moving cloth cords in and out of jacks on switchboards very rapidly, Sunday was usually a slow day, and smaller than usual (for a business day) staffs were on duty. In Chicago, which at that time had a mixture of dial exchanges and manual exchanges (about a dozen dial exchanges downtown, but manual service elsewhere in the city and suburbs), phone service came to a virtual halt about noon when the crush of calls based on the news report from Pearl Harbor generated a record volume of traffic in the history of phone service in our town. Chicago was no exception to the rule: all over the United States, telcos sent out urgent messages to every available employee to come in and help 'work the boards'; and even with a full week-day complement of operators by later that Sunday afternoon, delays of twenty minutes just to reach the operator requesting 'number please?' were not uncommon. In Chicago, the telco went on 'emergency calls only' status beginning about 2:00 PM and remained on that status until mid-day Monday, when the volume of calls had dropped back to a manageable level. The operators answered each call by saying 'We can only handle emergency calls at this time; (pause)....call later please'; then yanking the cord and moving on to the next in line of dozens waiting. Although the area around Pearl Harbor suffered extensive damage to telecommunications lines, the small exchange there stayed open throughout the bombing and managed rather well. (See Telecom Archives file 'pearl.harbor.phones' for specifics). Calls to Hawaii were blocked by the overseas operators in Oakland, putting them through only when the operators at Hickam Air Force Base (where the exchange was then located) told them they could handle more calls. Nothing like the volume of calls that day had ever been seen before; nothing like it was seen again until the day in November, 1963 when JFK was gunned down.

Martin) Data Over Voice (Richard Steele) ---------------------------------------------------------------------- Date: Fri, 8 Dec 89 01:24:34 EST From: Theodore Lee Subject: A Tangled Tale There is some kind of lesson in an annoying problem I just had with PC Pusuit that has taken Telenet a month and a half to resolve, although I'm not sure exactly what it is. But it does seem worth recording for posterity here. Our company's headquarters is in Maryland, in some sense midway between Baltimore and DC. We have arranged to be serviced by what I believe is called a "metro foreign exchange." It is in area 301, but dialable as a seven digit local (non-toll) call from metro (e.g, downtown) DC (area 202). For a good part of a year I have been using PC Pursuit's DCWAS outdial to connect to our computer. All of a sudden, in mid-October, my calls stopped going through. (The PC Pursuit dial command always returned Busy.) For some reason, whoever supplies Telenet with their telco information had, we eventually determined, made a mistake, and decided that our exchange was no longer a local call from metro DC, so calls to it were blocked by the outdial software. Tracking that down and convincing Telenet of the mistake is an interesting tale. At first, Telenet insisted it was a line problem: we have a Telebit Trailblazer on one of the lines; apparently the Telenet engineers had never heard its initial handshaking, which is not your ordinary 2400 baud Hayes, and decided our modem was bad or that there were local phone line problems. (It turns out that in fact we did have some C&P line problems at about this time, so at first I put the problem down to that.) Then they tried dialing from their Reston offices (area 703, not metro DC) -- and (of course?) they found it to be a toll call and reported that the exchange was not reachable. (We didn't realize until a little later that they were attempting to debug the problem from Reston rather than metro DC, where the outdial modem is.) About this point I was beginning to panic, having visions that the DC area toll structure had been redone without our knowing it. So I tried contacting C&P telephone to see what was up: my first call (to the service number for the exchange in question) shook me -- whoever I talked to said that the exchange was a Baltimore exchange, not a DC exchange. (At this point I should mention that I'm doing this from Minneapolis.) That didn't seem right (since I knew we had chosen that exchange specifically so that it would be a DC local call.) What I wanted to do then was find an operator in the exchange where the Telenet outdial was located and ask her whether the exchange I was trying to call was still a local call or not. It took me over an hour to find the right magic words to get my local long distance operator to talk to the DC local operator: there apparently is no way for a customer to be connected to a remote operator; my local operator kept telling me to talk to my long distance operator, my long distance operator kept telling me to talk to my local operator. After mumbling something about inbound service operator and stating my question, I finally did get my long distance operator to ask their operator the question, which was answered in one word, "Yes" (it is a local call.) Telenet wouldn't take my word for it and wouldn't make the same check themselves -- as far as I can tell, they had to wait for a new, updated (this time correct) exchange list. (To add insult to injury, somewhere in the middle of this process one of the Telenet service people decided the problem had been solved, when it hadn't, and closed out the first trouble ticket. And I almost don't want to mention, but will, that the engineers said it was poor beleagured David Purks' problem, whereas he said he was waiting for them to install the new, correct exchange lists.) To their credit, I do need to add that the Telenet customer service people I talked to really did seem to be trying to help and were as mystified by what was going on as I. The last time I was in DC I looked at a phone book and think I have a clue to what may have caused the problem: the exchange in question belongs to the town of Ashton (although our offices are not in Ashton). The boundary between the Baltimore LATA and the DC LATA goes right through the middle of Ashton, and I suspect if you look in some list somewhere you'll find Ashton as part of the Baltimore LATA, even though some of its exchanges are in the DC LATA and in fact local as well. Who says communications companies understand the business they're in?

PT] BASKING RIDGE, N.J. -- AT&T announced today it will make available 64 kilobit-per-second clear-channel access to customers who subscribe to its International ACCUNET (R) Digital Services and SKYNET (R) International Service offerings. Currently customers leasing an international digital circuit from AT&T who require bandwidth in excess of 56 kbps must use T1.5 (1.5 megabits per second) access for the local connection. "The 64 kbps rate is a common international data rate, and our multinational customers want and need the direct link that 64 kbps provides," said Elaine Kaup, AT&T Deputy Director -- International Product Management. The offering, which will be known as International ACCUNET Digital Direct Link Services and SKYNET International Direct Link Service, will initially be available from two locations in New York City and will be limited to the 64 kbps data rate. In early 1990, AT&T will expand the Direct Link offering to additional cities and will provide it at the commonly used Fractional T1.5 data rates (i.e., 128 kbps, 256 kbps, etc.). The effect of the Direct Link offering will be to reduce the overall cost of AT&T's International ACCUNET Digital Services and SKYNET International Service offerings to its customers. Customers of AT&T private-line services are connected to the international network via one or more of 28 AT&T International Pricing Points, located throughout the U.S. "By integrating data-rate-specific access into the cost of the international circuit, we are creating for our customers an offering that includes both a direct access link and the international half-channel circuit," said Kaup. "This package will be economical and customized to their specific requirements," she said. AT&T is issuing revised network specification information as an addendum to three documents: AT&T Technical Reference Publication 54019, the International ACCUNET Digital Service Description, and Network Interface Specifications. This addendum describes the interface -- which conforms to industry standards -- for the end-to-end 64 kbps clear-channel service. AT&T will provide Technical Reference Publication 54019 to manufacturers of customer premises equipment who write on their company stationery to Nayyar Azam, AT&T - Room 5359C1, 295 N. Maple Ave., Basking Ridge, N.J. 07920. The information will also be available through Corporate Mailing Inc., 26 Parsippany Road, Whippany, N.J. 07851 (1-800-338-4038). # # # Don H Kemp "Always listen to experts.

When I am in the office alone, I should be able to turn off the rotary so that only one incoming call can hit at one time. Any others should get a busy signal. That is preferable to them getting a ring that isn't answered, if I am tied up on the preceeding call. You will note that this is just the opposite philosophy from "call-waiting", which assumes that later callers have the right to interrupt earlier ones. My opinion is just the reverse -- the first caller has priority and later callers should wait their turn. It might be that some local PBX or in-house telecom system does offer this sort of user control. Right now, we are on Centrex and do not have that capablity, as far as I can determine. You can get something almost like what I am thinking of with call-forwarding by forwarding (to a perpetual busy) any of the calls that arrive at the second number in the rotary. I would prefer a simple user-available command which, when entered from the first number in the group, would shut down the rotary to the next one. Another simple command would enable it again. You wouldn't have to enter the number (the next one in the rotary) in any case. [Are "hunt group" and "rotary" two terms for the same thing, or are they different? The recently-distributed "glossary" implies they are the same by defining only "rotary hunt". I'm using them as synonyms here.] I get the impression that this and a host of other improvements to the telecom system are not available due to a basic difference in design philosophy between me (and other reasonable sane people) and the telcos. :-) This might be something like the difference between computer systems like UNIX (which ironically was engendered in Bell Labs originally) and systems like IBM OS's. One puts maximum control in the user's hands, while the other limits the user capability much more and vests control in a separate administrator. Since the telcos want to charge you for eveyrhing possible, they tend to the latter approach, making sure you have to go through them for all sorts of minor changes, which they can then bill for. Obviously, this approach is why the aftermarket in-house telecom system is such a popular item now that deregulation has made it possible. However, I get the impression (not being terribly familiar with such products) that most of these systems merely move the administration functions down from the telco's offices to a little tin god within the business itself, as opposed to moving all possible control (while still keeping security and accountability in mind) down to the user him/herself. In my mind, the ideal system would let an administrator set things up and make changes, etc., for those customers who don't want to do it themselves, but the system would also let the user do things on their own that are now restricted to "superuser" types. For example, an office would have a specified group of telephone numbers and the users within that office, when entering system commands from an instrument with one of those numbers, could do things like set up their own preference for rotary hunting, enable/disable functions like call-forwarding or call-waiting, shift the intercom functions and reassign numbers to other instruments, etc. They couldn't affect other offices' numbers or instruments, except for such limited things as making one the destination for call-forwarding. To shift things between offices would require a "superuser" type to be involved, but intraoffice changes wouldn't require the administrator. Doing things like establishing a hunt sequence would require more effort by the user initially, but the system should remember such things and let them then be switched on and off by minimal-length commands entered directly from an affected instrument by anyone inside that office. Are there any systems on the market that incorporate this sort of design philosophy? I'd be interested in reading about any that do so, or even approach this attitude. We are going to be moving to a new office building in the near future, and part of that transition is a leap to a new, non-telco in-house telecom system. Unfortunately, I am sure it will not provide anywhere near the level of user-friendliness that I described above. (Being a GSA low-bidder system, I will be amazed if it works at all... :-) Regards, Will [Moderator's Note: Actually, part of the 'wishlist' was resolved some time back here in Chicago. Illinois Bell offers 'Centrex Mate' (?) which is a sort of do-it-yourself service representative thing. From a terminal, you connect with the IBT computer and make service changes yourself. This option is only available to centrex customers. PT] ------------------------------ Date: Fri, 8 Dec 89 15:37:34 PST From: "Douglas W. Martin" Subject: How Were Telephone Sounds Chosen? I posted this request several months ago, but got no response. Anyone with any ideas or speculations is greatly appreciated. I am interested in finding literature references on how the various telephone sounds, e.g. dial tone, busy signal, and the decaying tone associated with credit card calls, were chosen. What kinds of psychoacoustic research were done to determine that these sounds are easily remembered, easily discriminated in noise, or less annoying than other sounds which could have been selected. I am looking for references on how these sounds were selected. Also, can anyone supply information about the frequency, duration, etc. for the off-hook alarm signal?

These are small boxes, about the size of a regular modem, that gives the user a 9600 bps asynchronous data line to the University computer. Not only is the bugger faster than a modem, _but it leaves the phone free for regular use_. We can still receive and make calls with the DOV working with no obvious distortion on the line. Thus, in addition to having a reasonably fast connection (and I used to think a 2400 baud modem was speedy!), I don't have to take the wrath of my roomates for hogging the phone line all night long. The DOV unit connects to the phone line before any other equipment; i.e. there's are line in and line out jacks. In addition, just like a Hayes Smartmodem, there are a plethora of LEDs on the front like CD (carrier detect), RD (receive data), SD (send data), etc. Question: How would something like this work? The phone company _does_ need to make some changes on their end, but the phone line remains the same. So, what magic is involved here? Thanks to all who respond... Richard A.

Now, the caveat is that the payphone will probably be programmed to intercept the call and go to an AOS (in the case of COCOTS only) in which case you have NO idea who is handling the call, and charging whatever outrageous amount to make that call. The incoming MF signalling from the local telco determines if the call is coming from a public or private payphone, and the MCI switch sees it is a 0+ call, and then sends the call to a switch which has an AOP (very few switches have AOP's still as of 6 months ago), then the usual AOP processes apply from here on. John's answer would be true, though, if you attempted to make an intra-lata call (within your service area), because the local BOC's don't subscribe/have access to the alternate L.D. carriers calling card databases. They only have access to AT&T's at the present time, though, this may change. BTW: MCI's AOP's are IBM PS/2 - Model 80's. >........................ If you have any volume discounts with these >carriers, your FONcard or MCI card calls would contribute to them, but >using your BOC card probably wouldn't. (You probably wouldn't get >your MCI "Around Town" discount either.) I was attempting to find out of the MCI Around Town discount was going to apply to BOC card calls, and the initial answer was 'No'. The problem was that Around Town determination was done at MCI's billing centers, not at the switch, and it was determined also by your *issued card number*, not the billing telephone number. I found out about this in my customer service days there, and the trick is to change your telephone number to that area's prefix, issue a card, then change back to your regular telephone number, and volia...you have 2 MCI cards with 2 around town areas. One area was based in San Rafel, and the other was based in Hayward (both in the San Francisco Bay area). Since the San Rafael card covered Marin and San Francisco for around town coverage, and the Hayward card covered the East Bay, I had Around Town coverage for most of the whole Bay Area! It was fun! Now that MCI has BOC billing, this trick could be a little harder since now MCI's computers do a check against the BOC's databases (this only applying to Pacific*Hell's........Pacific*Bell's area) when you sign up for service.

A few months ago I posted an article asking for help in getting a pay phone going that I bought at a hamfest. Well I got a few replies, one of which put me on the right track. Apparently since the Bell breakup any one can operate a payphone. As such you can buy "private" payphones from various companies that will work on normal phone lines. ATT sell a version of their payphones that they call a Private payphone. These differ from the standard BOC type payphone in that the phones themselves figure out how much to charge. This is done, in the case of my "Elcotel" phone (which incidently has everything except the electronics made by Weco (ATT)), with the aid of a rating module. This has stored in it all the information as to billing from the payphone's number to anywhere in the US. This phone also has stored voice announcements "Please deposit 25 cents", "Invalid Number", "Please call again, Thank you" etc. The phone waits till you have finished dialing before validating the number, connecting to the exchange line and dialing the number. It also has the 0+ bong stored (it deliberatly has about a 3dB S/N so as to sound like a long distance connection!! (on MCI I suppose). You can change rating information from the keypad (after entering the security code) or do it by modem. (i.e. dial upthe payphone which answers after 5 rings (programmable)). The payphone can also be made to automatically ring you up when the coinbox becomes full, or when it is being vandelised! The phone works out that you have connected, and thus takes you money, by doing a voice signature analysis! (Very clever...) It has alot of ways of redirecting your long distance calls to your favourate LD co. (It is set up initially to reject 10XXX calls! but this can be re-programmed). New, these phones are about $1500 and up! Much better if you can find a hamfest. (I payed $125 (and all that was wrong was that the keypad was miswired and the tone-progress detector chip was fried)) The BOC type phones a dumb phones with the billing worked out at the CO, and voltage "wink" to tell the phone to take your money etc. If you're a business C&P (in our area) may put in a payphone for you and give you a slice of the profits. (but if you just want a REALLY sturdy phone for home,(you know, the ones as strong as the phones that you got from Bell before the break-up) you're out of luck) email to UUCP: uunet!mimsy!{arinc,fe203}!vk2bea!michael _ _ _ _ Amateur | VK2BEA (Australia) ' ) ) ) / // Radio | G4NYV (United Kingdom) / / / o _. /_ __. _ // Stations| NV3Z (United States) / ' (_<_(__/ /_(_/|_ Subject: Re: How Can 411 Be Flagrantly Abused?

It takes many hours to get a connection. Often that doesn't happen at all. It has become basically impossible to make important phone calls. Even attempts to use telegrams are almost hopeless. All regional postal administrations report that telegram traffic is totally overloaded. The telephone system of the GDR has not made the switch to digital technology. The existing system is based on analog switching, just as it was the case in West Germany not too long ago, and is outdated. There are bottlenecks in switching and the cable plant. Microwave links would have to be set up between the Federal Republic (W.-Germany) and the GDR. How tight capacities are can be seen by the fact that a total of 1313 conversations can be accomodated concurrently from the Federal Republic while from the GDR only 215. East Berlin and 221 other localities can be reached without operator assistance. According to figures provided by the postal administration in East Berlin, more than one million residents of the GDR have applied for a telephone line. 45000 additional lines had been planned for 1990. In the Federal Republic, 97 of 100 household have a telephone, in the GDR only 16. There are 27.5 mio. phone lines in West Germany, 1.6 mio in East Germany [population is 61 vs. 17 mio, roughly]. The postal administration in Munich points out that in early November, 250 calls were registered per day. Today, the number is 950. Only every tenth attempt for connection is successful when direct-dialing. According to the postal administration in Lower Saxony, only every fifth caller has a chance of getting through. ===== Henning Schulzrinne (HGSCHULZ@CS.UMASS.EDU) Department of Electrical and Computer Engineering University of Massachusetts at Amherst Amherst, MA 01003 - USA === phone: (413) 545-3179 (EST); FAX: (413) 545-1249 ------------------------------ From: Brian Gordon Subject: Re: Phone Solicitations (Again) Date: 8 Dec 89 18:45:16 GMT Reply-To: Brian Gordon Organization: Sun Microsystems, Mountain View In article <1902@accuvax.nwu.edu> 10e@hpcvia.cv.hp.com (Steven_Tenney) writes: >X-Telecom-Digest: Volume 9, Issue 557, message 5 of 11 >Oregon is soon to pass a law where a subscriber can have a symbol >placed by their name in phone books indicating that they do not want >any telemarketers/solicitors calling.

BTW, to get credit for a call that didn't go through, you must get that 700 operator again. When you are there, it isn't much better. The 4 wire 75 baud 20ma data circuit was down. After three days, the telco man showed up at site. His first move was to call his test board. To do that, he had to find a working outgoing trunk. Since only 3 or 4 of 20 work on any day, this was a bit of a problem. Now his butt set consisted of a 300 series handset with braided insulation cord. No dial. No network I could see. He looked for a trunk on the protector with it. Since some were ringing, he jumped a lot. When he got one, he dialed by banging his pliers on the protector terminal. After 15 minutes of this, I loaned him my Buttinski. This took a translator to explain the Monitor/Talk switch. After many calls, he got through to the board (I always knew that redial on a butt set should be an option) When I left a day later, they were still working on it.

Britain is set to unveil big ISDN push, at last. After years of pushing back the introduction of ISDN, British Telecom is now planning a great leap forward. Instead of installing 1,500 ISDN basic-rate interface (2B + D) lines in the first year as originally planned, it is telling suppliers that it will install 50,000 lines during 1990. Plans for the following years have been given a similar upward thrust, in line with a memorandum of understanding between European PTTs that ISDN will be made available to 95 percent of business customers by the end of 1992. Currently, the UK has about 1,000 "ISDN" lines installed as part of BT's nonstandard Integrated Digital Access (IDA) service. ==================================== And reproduced from a photocopy that landed on my desk a few minutes ago... Plans for the digital communications era of the future have been unveild by British Telecom with the launch of an advanced service to carry voice, data and pictures. The service, "British Telecom ISDN 2", will pave the way for more high-tech applications such as the picture-phone, ultra-fast fax and high-speed data transfer. ISDN 2 will provide high-speed digital services to branch offices and small and medium businesses. Such services have, until now, been available only to large business sites. The launch follows a 23 million pound order with STC Telecommunications for equipment to provide up to 90,000 lines of network capacity. Nick Kane,BT's Director of Marketing and Sales said: "Our new service, the first ISDN service in the world to conform to the latest international standards, enables a broad spectrum of our customers to take advantage of information technology services previously only available to large businesses. In doing so it will accelerate the introduction of the information society." ================================== Trying to disentangle this from the marketing blurb ... ISDN 2 is "true" ISDN and seems to be based on standard I420. The older ISDN 1 was BT's Integrated Digital Access (IDA) service and was based on the 1980 ISDN standard which got changed (oops...). What interests me is why we all found this out from external sources when we are in the division that is supposed to be supporting the introduction of ISDN.

Invalid observation: In-State Directory Assistance in Massachusetts is free to residential customers. (Can't expect you to have known this.) This may be partly due to the cost of distributing directories of everyone's local calling area. Although Acton's local calling area only includes the four exchanges Acton/Boxborough, Concord/Carlisle, Maynard/Stow, and Littleton, not all of these towns are in the local phone book (Littleton is in another book). Each of these other towns has at least one local exchange that is in some other adjacent phone book. It would not be possible to re-align the books to solve the problem, since _each_ town has a different set of surrounding towns. (I suppose it would be possible to list towns in more than one book, but that, too would increase the cost of the books.) Apparently N.E.T. has determined that the cost of distributing an additional phone book for all the adjacent areas to each customer (a requirement before the DPU could get away with permitting a D.A. charge) is higher than the cost of D.A. (At least all N.E.T. phone books can be had for free for the asking.) But I'm sure that residents of Massachusetts don't feel that Mr. Cohen was some sort of hero for reporting the abuse. Rather than helping to preserve our free access to D.A., Mr. Cohen's report is more likely to be used by N.E.T. as ammunition in their attempts to get approval for a D.A. charge without the requirement that nearby phone books be delivered without a special request. I'll try and see if a residential D.A. charge is part of N.E.T.'s $16 million rate reduction filing now pending before the D.P.U.

This service IS available, today, from 1ESS and 1AESS central offices in New Jersey. It may be available elsewhere. I don't know the USOC for it, but it is a tarrifed service. It is implemented as a separate pair from the CO to the customer premises. At the customer end, they install a simple keyswitch that either opens or closes the pair. If this switch is open, hunting works normally. If this switch is closed, calls dialed to any number in the hunt group ring only that number - or reach a busy signal. It is used by customers who subscribe to answering services, who want calls dialed to their main number to reach the service after hours, or a busy if the service (presumably only connected to the first line) is already talking to another caller. It enables late-workers to receive calls on numbers other than the main LDN. Dave Levenson Voice: (201) 647 0900 Westmark, Inc.

We are moving soon, and want our main number to follow us for a while. Answer: call forward. Problem: if our main number gets forwarded, that over-rides the hunt we have. So, if anyone calls any of the other lines in the hunt, which will all be disconnected, they get disconnect notice. If anyone calls the old main number while someone is still being forwarded, they don't hunt, they get busy. So, forward overrides hunt. Forward your first line to the second. This will make all calls come in on second line, but the forward gets handled first, so subsequent calls get busy as first line is busy while forwarding to second.

(A bit With the proliferation of wireless devices, the public (and the public's representative--congress) seems to have become numb to the reality that the airwaves are nothing more than a big party line. To use this big party line, people have to cooperate, realize that their use can be monitored by others, and accept the laws of physics that relate thereto. I had to field a call once from a very irate person who had been informed that the reason her garage door opened occasionally on its own was because of signal from my client's FM radio station. Garage door openers operate at a frequency that is roughly the third harmonic of the center of the FM band. While it is possible that a broadcast could have measureable output on the third harmonic, it would be unlikely that it would exceed FCC limits (which are well defined). Coincidentally, I had been doing other work on the transmitter and happened to have measured the station's third harmonic and found it to well exceed FCC requirements for suppression. When I informed the person of this, she became even more irate and told me that she didn't care about FCC rules, it was the radio station's problem, pure and simple. Not having a lot of time to waste, I directed her to the statement on her unit which declares that the user must accept any interferrence and must not interfere with any other devices or services. She felt very wronged but I am sure that she gave no thought to the big picture--that a radio station serving hundreds of thousands of listeners be put on the same priority footing as her (probably defective) garage door remote control. I told her it was her problem to remedy and it would have to be at her expense. Sorry, that's reality. >If I'm really bent on wireless >intercoms inside my home, I should either accept the fact that I am >voluntarily BROADCASTING, or at least take measures on my own to see >that the transmissions do not leave my house.

Using the party line analogy, those with experience in this area have observed that sometimes people fight over the use of the party line, just as they sometimes do with the radio spectrum. Perhaps it's my radio background, but whenever I use a cellular phone, the thought never leaves my mind that the conversation is on the air and that at least someone else, not a party to the conversation, is listening. If the message is critically private, we move to landline. It's like breathing and eating. That's why this privacy flap is so funny. If you want to use the public airwaves for private communications, then it is up to you to encode them sufficiently to keep them private. But for someone to intentionally bug their own house (baby monitor), put it (unencoded) on the air, and then get angry when someone does the inevitable evesdropping, well... John Higdon | P. O.

From those who know how the technology is progressing? >From potential owners? Funny you should ask. Yes, there's a new ISDN 7 kHz audio bearer service. It makes use of 64 kbps ADPCM encoding. (Digression: Standard PCM uses 64 kbps to do 3.1 kHz audio. ADPCM is more efficient, so 32 kbps is essentially adequate for 3.1 kHz audio, with only minimal distortion (modems might complain, humans won't). So if you use the ADPCM principle on the usual 64 kbps bandwidth, you can get better audio.) The network uses PCM to generate tones and announcements for ISDN telephones in the telephony bearer service. The 7 kHz standard says that you begin all calls in standard 3.1 PCM mode, specifying that it's really a 7 kHz call. Once the two ends are connected to each other, they do a handshake to confirm that they're ready to switch into 7 kHz mode. That way the terminals are in 3.1 PCM mode when doing call setup (talking to the network) and in 7 kHz ADPCM mode when actually communicating with each other. This hack makes it essentially transparent to the network, which will speed implementation. You just need the chips in your telephones. I don't personally see much use for it in "handsets", given their cruddy mic/speaker combos, but it could be very nice for speakerphones, audio dial-up program services, remote broadcast feeds, etc. fred (member, ANSI T1S1, speaking for himself) ------------------------------ From: Steve Elias Subject: Re: Data Over Voice Date: 10 Dec 89 16:19:11 GMT Reply-To: Steve Elias Richard Steele writes: >Here at Purdue U., we now have access to something called data over >voice (DOV) units.

CNID will allow YOU to determine if you know the party calling and accept the interruption. It would make sense for you to ask for the phone company to not implement CNID on your outgoing calls. Then, when you call someone as insistent as you are about your right to remain unidentified, that person can ignore the call because the calling party chose to not identify itself. The phone companies are BUSINESSES. Due to the common opinion that phone service is a RIGHT (its really a purchased service), the government decided early to regulate it. Gregory G.

Wrong. What you buy is your credit card company's business, your bank's business, even the IRS's business if you deduct for business purposes. Where you go is generally known by your credit card company. Who you call is known by your telco, your long distance company, and the IRS if you deduct telephone calls. Whenever you use the telephone, your number is given to the long distance company for billing, to the business you called if you used an 800 number, to the information provider if you called a 900 number. These many businesses (some of whom ARE scumbags) already have access to your number. What you seem to be against is the private individual having this same information. >More than adequate means already exist to trap prank and obscene >calls.

It sounds like you are carrying a lot of baggage concerning your affairs. Why do you think that your precious unlisted number will be compromised in a world with Caller-ID? Who do you call that will spread it around? If you thought that you didn't want me to have it, for instance, I would invite you not to call me. After all, what gives you the right to bother me if I can't "bother" you? If you are so hung up about all this, get two lines and use the listed one to make calls to those whom you seem to want to call without them being able to call you on your unlisted number. >I insist, no, I demand that a ring on the phone is either someone I >want to talk to or is an emergency. All caller ID will do is allow >slime to discover my phone number more readily. I have more unlisted numbers than you do. I have nine; how many do you have? Am I afraid of Caller-ID? Absolutely not. Those who know me will also tell you that I am a staunch advocate of civil rights, the right to privacy, and that I am a strict constitutionalist. But Caller-ID is not snooping by the government--they don't need it. It is not snooping by big business--they don't need it. It is a useful tool that puts just a little more control of the telephone back into the hands of call recipients. You have yet to convince me why that is undesireable; your obvious paranoia notwithstanding. >Hmm, instead of getting mad, perhaps I should take advantage of the >entraprenural opportunity.

Presumably you'll have a better idea if you want to talk to someone if you know their phone number before you pick up the phone... > All caller ID will do is allow slime to discover my phone number more > readily. Depends on who you call; I'd like to note that telesalescreeps managed to find my second line even though Caller-ID was [obviously] not available at that point.

Let me first disclaim... While I am an Honest-To-Goodness employee of Ameritech Applied Technologies, I have never been a Telephone-Company-Person. I was hired for my UNIX skills and that's what I do, *but* you can't work around here w/o soaking up knowledge about the network. That said, the facts as I know them... Once upon a time, everything was pulse. The step-by-step switches whirred along nicely. Then they started selling DTMF service to the subscriber, requiring pulse-to-tone converters. It was generally more cost effective (at least here in Wisconsin) to wire an entire office with this equipment than the individual subscriber, so this was what was done. This stuff persisted through the SXS, the Crossbar, and most of the #1 and #1A ESSs. The end result of all of this is that if you did not feel any twinge of guilt at committing petty larceny against (what was at that time) AT&T, you could pilfer DTMF service at no cost except (potential) guilt. Once digital switching started to get more and more widely propagated, however, things changed. With the advent of the AT&T #5ESS (and presumbaly the DMS 10 & 100), the switch was able to recognize Pulse or DTMF on its own instead of relying on some piece of hardware in the network to perform conversion. The end result--if you don't pay for the service, you can't use it. I cannot comment on whether or not I think that DTMF should cost less than pulse, but consider the people still served by older switches who should pay more for something that extra equipment is required to provide...

My story: I had purchased two products that might have qualified - a KXT 3000 cordless phone and a KXT 2432 phone/ans. mac. combo. While the first was listed in the qualified products, the second one was not; in fact it's white colored sibling KXT 2429 was. (2432 is black but otherwise identical to 2429.) I called up the Fund office about this product and was told that it is possible that they may allow 2432 as well and asked me to send in the application, which I did. I did not have the receipts, so I sent in cutouts from the boxes, showing model numbers, as they had instructed. After about a month or so, I get back in mail a letter saying that my application is rejected because I have the wrong model numbers. Both my proofs of purchase were cut in half and sent back. I call them up; they tell me that 2432 is not allowed. So I ask why the other part was returned. The woman didn't know anything about it and asked me to resubmit the application for the KXT 3000. After another month and a half, I get back another letter in mail saying that my application has been denied on the grounds of *wrong model number* as well as *missing serial number* which I had provided!

I have a KXT3900 cordless connected to a single-line port on my 1232. I can answer any line, place a call on any line, answer any ringing extension, answer and call my [homemade] doorphone, conference calls, receive second call indication at the handset, access speed dial, have system last-number-redial, park and retrieve calls, and access internal and external paging. The phone itself scans the 10 channels for a vacant one when you go off hook and allows the user to change channels should one become unusable during the conversation. The price for all this? I paid $149.95. That's nearly 400% less than AT&T's remarkable breakthrough. It also has a one-year warranty, but I'm not stupid enough to get a maintenance contract.

This was the topic of a meeting at the State building in San Francisco a couple of months ago between PacTelesis, information providers, and a rep from the PUC. A lot was discussed, but the long and the short of it is that since Pac*Bell controls the network, they could and probably would use every trick in the book to unfairly compete with independent providers. Once they gained a monopoly (in a completely unregulated market), they would only concentrate on lucrative aspects of the service. Since the PUC is not really sympathetic to Pac*Bell on this issue, it appears that they have taken to the streets. To see how information services provided by Pac*Bell would evolve, just look at the nation's cable TV industry. Cable companies scrambled to get exclusive franchises in cities across the US, promising to offer, not only TV stations from all over, but interactive services, educational services, and cultural programming. What did we really get? With minor exceptions, there is no interactive capability, they dropped the "out of area" TV stations and substituted all manor of over-priced pop-market pay channels. There are shopping channels, pay-per-view channels, and the rates have gone through the roof, even though technology and economies of scale would contraindicate the present high cost to the consumer. > If the Bell companies could develop and provide these services, > along with many others that people in other countries take for > granted, they would become more widely available, and growth of this > market would encourage more information providers to enter it. This is blatant nonsense. If the market is so promising, why aren't entreprenuers falling all over themselves to enter it now, as they are perfectly able to do? Is the reasoning that just because a "Bell company" enters a market that a stamp of approval has been issued? > 1.

We are in a similar position with a backbone using ethernet and routers, and with ISDN compatible PABX's. We intend to make almost NO use of ISDN internally. We will be deriving B-channels for some of our intercampus traffic, and running them between routers, i.e. TCP/IP will be there at layers 3 & 4 but we don't have an interface problem because our (Plessey) digital handsets provide a standard X.21 64kbps interface. What you need to solve your problems are some ISDN Terminal Adaptors (TA) of various flavors. The problem is they haven't been developed yet! In (a) above you need a pair of asynch TA's, i.e. TA's which map various asynch speeds onto a 64k channel, enabling access to some sort of terminal server. In (b) we all hope there is a PC card coming which speaks BRI. Of course you need to connect somewhere, so it might be slip after all. For (c) a TA which can bridge ethernet segments would be fine. Clearly there is a long way to go with data access to ISDN, and there is room for a lot of innovative product development. Start shouting at your suppliers NOW.

The group I am contracted to here in AT&T manages for the local employees a service called 'CO Lan'. The box originally described, called a VDM for Voice-Data Mux, gives a 19.2K connection on the local pair (NOT a second line as suggested above) by modulating it out of the voice bandwidth and runs that back to the CO (which must be within a certain distance, 5 km I believe). There is no need for a digital link as suggested elsewhere above. At the CO it is split back out and run into a Datakit (TM, I'm sure) circuit switch and connects into the AT&T internal network. The RBOC's are marketing this like crazy for terminal connections and low-speed networking in a 'campus' environment, where the buildings are sufficiently close to take advantage of such an arrangement. The switches can also be trunked together to provide wider-area networks. For those of us with a PC at the house that we like to use in the evening to read news :-), or in a college/university environment as described above, it seems a useful way of providing general connectivity without major add-ons to physical plant; no new wires to string, just put the data switch in the CO and hand out the VDM's. There is also some improvement of security, since you are not providing generic dial-ups.

They are carrier-frequency devices that share the local loop to provide a permanent modem circuit on the subscriber pair while allowing normal use of the telephone. The data signal is recovered by a "modem" box (twin to the one on the subscriber end) where the line enters the PBX. I recently learned that our local GTE outfit offers DOV on residential lines. The DOV circuit goes into a CBX (data PBX for asynch traffic) and is delivered to other DOV lines or to dedicated business data liens on the other side. (I wish they had an X.25 option on the other side). Several of the high-tech companies in town have access lines to this switch, as does the university (UCSB). The DOV facility provides 19.200 bps service for about the same cost per month as an extra residential subscriber loop. Unfortunately, my employer is unlikely to replace the current 5 dial-in lines with connections to this service. / Lars Poulsen (800) 222-7308 or (805) 963-9431 ext 358 ACC Customer Service Affiliation stated for identification only My employer probably would not agree if he knew what I said !! ------------------------------ From: Gary Segal Subject: Re: Data Over Voice Date: 11 Dec 89 20:09:27 GMT Organization: Motorola INC., Cellular Infrastructure Division steele@ee.ecn.purdue.edu (Richard Steele) writes: >Here at Purdue U., we now have access to something called data over >voice (DOV) units.

Carnegie-Mellon University has had something called "Metropolitan Campus Network" (MCN) for a while (since fall 1986, I think). It gives people on certain CO's a 9600bps data link to the campus computing network. It is implemented using Gandolf DOV modems (model number escapes me), which sounds very much like the beast Purdue is using. When installed, the connection looks like this: +-----------+ | 2-wire to CO | +-----------+ =======| DOV Modem |=======================| DOV Modem |========= 2-wire | | | | | in a Bank |Many Pairs to VF | | | | | O' DOVs |to CO equip. +-----------+ | | +-----------+equip. (phones, ! | | ! modems, ! | | ! faxes...) ! | | ! ! | | Many RS-232 links to RS-232 to computer | | data switches & | | terminal concentrators | | Customer Premise | Poles, etc... | Central Office VF = Voice Frequancy How does it work? Simple, if the line between the CO and the customer premise is pretty good, you can get more than 300-3400Hz bandwidth out of it. The DOV modems use carrier frequancies above 3400Hz. They have a filter that sits between the DATA/Voice side and the VF side that removes the data signals. In addition, all of the normal telephone signals are passed through without changes. At the CO end, the data is "peeled" off before the channel banks or other such CO equipemnt. Thus, the DOVs are transparent to VF and telephone signaling. In order for this to work, the pair from the CO to your premise must be pretty darn good. When MCN was first offered by Bell of PA and CMU, they listed the exchanges that you could get it on. I believe they had installed DOV shelves in three CO's, so if you were attached to any of those, you could get it. In addition, they stated that if you were more than a certain distance from the CO (2 or 3 miles, I think), it wouldn't work. There was also talk of making a 64Kbs link availible, however I don't know if it was going to be by DOV or ISDN. Oh yeah, it was fairly expensive for your average student, something like $100 to install, $200 for the DOV and $25 a month. Maybe somebody at CMU can bring us up to date on the current state of MCN.

[There was] a lack of available pairs [which was solved] by installing [something] called a "slick-96". I believe it's a SLC-96 (pronounced "slik-96"). It stands for Subscriber Line Carrier, 96 channels. They use T1 (or similar) connections from the box to the CO, this gives them 96 subscriber drops off the box. It comes in various sizes, I have also seen sizes for one or two T1 circuits and for a T3 circuit. The latter was installed in an industrial park where I was working and (except for a short interruption when the installer accidentally cut the wrong wire :-) we couldn't notice the difference. Running one T3 circuit back to the CO was cheaper (or as cheap) than stringing another N-pair cable, and it freed up pairs for use in neighboring residential areas that were also expanding. These units seem to be much better than the ones they try and use to get two lines out of one. You probably lucked out that they didn't just do one of these funny mux things between you and whoever you formally shared the pair with. Maybe the tariffs don't let them use those when they're two seperate residences. ------------------------------ From: Bernard Mckeever Subject: Re: Slick 96 Date: 11 Dec 89 19:04:10 GMT Reply-To: bmk@cbnews.ATT.COM (bernard.mckeever,54236,mv,3b045,508 960 6289) Organization: AT&T Bell Laboratories Slick 96 is really Subscriber Loop Carrier - 96 or SLC-96 {R}. This type system may also be referred to as a Digital Pair Gain System because is requires fewer outside plant pairs to serve a larger number of customers. You are quite correct to assume that it is a MUX, but it is a form of T1 MUX [1.544 Mbs] based on D4 channel banks. SLC-96 may be configured in several ways for POTS, Special Service, or a mixture of both. Mode 2 allows up to 96 subscribers on 48 time slots. A typical SLC system will have at least 1 protection T1 span and a few metallic pairs for test access and other maintenance applications. SLC systems will work with coin stations. The remote terminal may be mounted in cabinet, pedestal, vault, or customer location. Each remote terminal works with a central office terminal, or connects to a digital switch via a interface module. SLC does not use the two most popular framing patterns SF and ESF and can not be directly connected to a channel bank without framing conversion. Does it do tricks? Yes! It allows 1FR service in areas where the TELCO does not have enough outside plant to support it. For people having that nasty problem of a bunch of [[[[ messing up your modem connection, [you know who you are] the problem may be between a SLC system and your brand new Digital CO. SLC-96 is not the first or the last of the pair gain systems, SLC-1 was an added main line service that provided 2 lines over one pair. SLC-40 [an analog system] provided additional capacity and the newer systems are smaller and employ many additional features. No tricks. You can order 56 Kbs private line service over SLC and expect the same results as you would over CO based services. If your CO supports ISDN, SLC has a channel unit available to provide this service. In short SLC systems extend the range of the central office and outside plant without costing as much [by far] as a new CO.

Can it do any tricks? We, too, have service from the local telco via SLC-96 (which is Subscriber Loop Carrier, 96 channels per T-1 span). This system uses digital multiplexing and local switching to concentrate a large number of subscribers on a small number of 1.55 Mbit digital loops to the CO. It regenerates battery feed, ringing, loop current interrupts, and anything else needed to support your local Tip and Ring telephone sets. A group of T-1 links to the CO (or fiber, in some installations) provide the physical circuits. Each T-1 link supports 24 derived voice circuits, using digital multiplexing. The actual ratio of supported subscribers to available derived circuits is engineered to provide an acceptable blocking probability, based upon the traffic generated by the subscribers served. When you're using a CO line, you get switched on to one of the available derived channels. When you're not, no channel is assigned. It's fast enough that you'd never notice it, except for the minute probability that no channel will be available when you want service. In that case, you'd experience a wait for dial-tone, or a party calling you would experience a fast busy (I think). We have run voice and data through that mux for several years, and have never experienced data integrity or blocking problems. The transmission quality is noticably better than it was when we had loaded-loop metalic circuits, a few years ago. When it was first installed, the remote terminal was buried in a vault under a man-hole a few blocks from here. There was a lot of excavation, and lots of noise while it was under construction. This moved a few of our neighbors to ask the town zoning board to deny permission to the Telco for use of their easement in this manner. I don't know how the politics finally were resolved, but the mux was cut back in about 1986 or so, and probably bothers nobody today! Dave Levenson Voice: (201) 647 0900 Westmark, Inc.

Date: 11 Dec 89 05:13:25 GMT Reply-To: tell@oscar.cs.unc.edu (Stephen Tell) Organization: University Of North Carolina, Chapel Hill A related question on choice of tone signals: Has anyone else noticed that a lot of people in the "general public" (non-telecom-junkies) can't tell the difference between a busy and a reorder, or maybe don't know to listen for the difference in interuption rate? I'm still in touch with a lot of people at Duke University, where I used to be a student, but now I'm just beyond the area that is a local call for people on campus. It has happened many times that someone has tried to call me from a restricted campus phone (local-only, like a public non-coin phone), and complained "Your line is always busy." The Duke phone system (their own 5ESS) gives reorder for this case, also for the case of dialing only 7D when 1+7D is required. The latter may be more the problem, since GTE in Durham (around Duke, off-campus) doesn't want the leading 1. I explain "that's not a busy signal" and get funny looks from people who never heard of reorder, but I wonder how many calls I miss this way? (Perhaps this is an item for RISKS?)

That's two non-thinking replies to the same point I just read. This person is saying that if you ignore phone calls, you can be ignoring important emergency noticies. Then two people claim that if they don't know the number, then it can't be that important. Do you know the number of all the hospitals in the area? What about the police stations? You cannot just ignore phone calls from numbers you don't know. So you gain nothing by having ANI except being able to recognize numbers you don't want to talk to. And since you're already at the phone it is easy enough to just pick it up, hear the voice, and hang up. ANI gives no effective new features to end users. It gives plenty of ABUSE to people compiling information and selling it.

The Hungarian cellular system will be the first such telephone network in Eastern Europe. Because of the shortage of telephones in their country, Hungarians are expected to use cellular telephones for basic home service, as well as mobile communications. For Hungary and the other Eastern European countries that have antiquated telephone systems, it will be faster and cheaper for the Government to deliver telephone service by cellular networks than it would be to rebuild the nation's entire telephone apparatus. A cellular telephone network transmits calls on radio waves to small receiving antennas, called "cell" sites, that relay calls to local phone systems. The system to be built in Hungary will transmit calls from cellular phone to cellular phone and through the existing land-based telephone network. The system, which is scheduled to begin operation in the first quarter of 1991, will initially provide cellular communications to Budapest's 2.1 million residents. Eventually, the system will serve all of Hungary, a nation of 10.6 million. Hungary has 6.8 telephone lines for every 100 people, according to The World's Telephones, a statistical compilation produced by AT&T. By comparison, the US has 48.1 lines for every 100 people. ***End of article*** [Note: an abbreviated and slightly different version of this article was posted to the RISKS Digest.

Woodbury" Organization: Wolves Den UNIX BBS Date: Wed, 13 Dec 89 03:57:35 GMT Just a quick report to the Telecom Digest concerning CLASS services in the Central NC area. Southern Bell (part of BellSouth) in central NC (specifically Raleigh area LATA) is offering CLASS services without CNID. The NC PUC has the CNID service held up in red tape while ACLU and other "intervenors" complain about privacy etc. Last # redial, last caller autodial and "wardialer" services (as well as call trace) are being heavily advertised on local TV. The GTE satrapy in Durham is finally advertising that they have the disable call waiting service in place, but it is not generally enabled in the switches - you have to specifically order it. Both phone companies are still charging for DMTF services. GTE disables DMTF by reversing polarity on the line at the switch frame. (i.e. you can remove "Touch Tone" from your line charges, and in about a week your modem and DMTF phones will generally stop working - but a check with a polarity reader (the led on a stick) will indicate that the polarity is "reversed" -- I know I wired it right when I redid my parent's place a couple of years ago ;-) GTE spokespersons said that CLASS services will become available in Durham in about 6 months or whenever the PUC finally decides the issue of CNID. An inquiry about the difficulty of re-programming the CO switches was met with a snide remark and a statment that the phone switch software is the most recent available from the manufacturer. Private information is that Durham is all NT DMS-10's and that the NT/BNR complex in RTP is working on it as fast as possible. Gregory G.

Herber It is a Subscriber Line Interface Circuit (96 lines). Yes, it is a mux. Yes, it is digital. No, it does not do tricks. It is used to concentrate 96 subscriber circuits to a single metallic line or optical fiber which then runs to the telephone exchange. In your case, it is probably using your original metallic line.

The 96 stands not for "9600 baud", but for the 96 lines that are concentrated onto a T-1 type trunk interface, which normally carries 24 channels. The quick will notice a 4:1 ratio on the SLC-96. I don't recall the signalling protocol. Paul Guthrie chinet!nsacray!paul ============================ From: Paul Elliott x225 Date: 12 Dec 89 16:02:18 GMT Organization: Optilink Corporation, Petaluma, CA The box referred to is a "SLC-96 (tm)", which stands for "Subscriber Loop Carrier - 96". This is a four-T1 system. A T1 circuit uses two pairs of special wire, running at a digital rate of 1.544 Mbit/sec. Each T1 circuit carries 24 channels of PCM. 24 channels times four circuits equals 96 channels, hence the "96". The SLC-96 has been in service for many years, and has been widely cloned. It is a convenient size for providing service to remote clusters of subscribers. The SLC-96 can provide some types of data service via different line card plug-ins, however I am not familiar with all the offerings, or the cost and availability of them. Can anyone out there comment on this? Regards, Paul M.

(I guess DS2s do exist outside of add-drop multiplexors.) The data rate is 96*64000 bps plus DS1 and DS2 framing overhead, or somewhere around 6.2Mbps. I don't know if you can get DDS (56kb/s) or T1 (1.544Mb/s) lines off of a SLIC, though. I have heard (rumor only) that it is possible - if the switch software can handle it - to provide basic rate service on some SLICs by dedicating 3 lines for D, B1, and B2, plus the appropriate hardware.

Here in Bell Atlantic we offer this as a tarriffed service it is called LANgate or Central Office Local Area Network. See your local sales rep for prices. How it works...... That box that has jacks for your phone and your terminal converts your terminal signal from digital to analog. The box then Frequency multiplexes your voice and the analog data onto the same copper pair. At the Purdue Central Office this process is reversed. This is an excellent way to provide 9600 bps without wiring changes or expensive modems.

In Pittsburgh, this service is known as Metropolitan Campus Network (MCN) and is provided by some combination of Carnegie-Mellon University (CMU) and Bell of PA. My house was a beta-test site for this service a few years ago, and in the many technician visits I picked up a few things. I have since moved, so some of the details may have changed. Two DOV modems are actually used for each house served. One is placed at the Bell of PA Central office(CO), between the switch and the cable pair to your house. The second DOV is installed in your house, electrically between the Network Interface Jack and your existing household phone wires. +---------+ | Central | voice +--------+ data and voice +---------+ voice +---------+ | Office |-------| CO DOV | ----------------| user DOV|-------|telephone| | switch | +--------+ +---------+ +---------+ +---------+ | | |data |data Port Selector in CO--- + +-------Home terminal or PC The modems communicate using frequencies above the voice band. The DOVs completely ignore all of the normal telephone signals, allowing uninterrupted data communications regardless of whether the phone line is in-use, ringing, or idle. The DOV operates as 64Kb synchronous. In order for the DOVs to work you must be within a pre-set distance (I think on the order of a few miles) from the CO. The real problem with this setup, is that it only allows you to communicate with the CO. Bell of PA installed port selectors in three of the COs near CMU. These were connected by fiber to CMU. At my house, I just plugged my terminal into the DOV, and hit return. This got the attention of Bell's port selector. There were few destinations at CMU that I could select (Most of which were additional port selectors or terminal concentrators). When I left the program, only 9600 and 19.2 kBd async was supported, with plans for 64Kb, possibly using Serial Line IP. The most amazing thing was that the system worked very well. Voice and data operated independently on the same copper pair. Incoming and outgoing calls did not affect data at all. I have no idea what the applicable tariffs were. Payments were made to CMU, but installations and service was provided by Bell of PA. I was always amazed that the Bell service operators (just dial 611) were able to cope with MCN trouble reports. The biggest problem during the testing phase was noise on the phone line. The DOVs went through quite a few revisions before there was no audible interference with the standard voice usage.

I spent five years (83 - 88) as part of Ericsson's ISDN terminal project. We did produce a feature-phone and a range of TA:s which conform very closely to the "official" ISDN spec. The deviations were due to the fact that the specs aren't yet quite waterproof. There are, to put it bluntly, holes in the protocols at some places, so we had to device ways around these. Ericsson's terminals are available NOW for Ericsson customers. The TA:s handle V24, X21 and X25 to mention the more popular protocols. The only problems are availability and the prices... You see, we started that project way back before any VLSI:s had appeared on the market (actually, we cooperated closely with AMD in their work with their chipset) and the custom-circuits used in that first generation of terminals are *expensive* and hard to get. This puts the prices of the terminals at a level few customers can handle and in reality all sales so far have been to Telcos using Ericsson equipment who want to set up field-trials for ISDN. So why don't we re-build them using state-of-the-art hardware and market quick as hell? Partly because the afore-mentioned gaps in the protocols are still there, no *true* standard exists. Partly because no-one in their right minds ventures a project like that when it's well known that several major Japanese producers have competing products in the pipe-line. We're a high-tech, high-cost country. We can't compete with far east producers when it comes to volume sales and all projections indicate that we'd get the market kicked out from under our feet well before we'd made our investment back. However, all is not lost. There are at least a couple of Ericsson trials going on in the U.S. today so if you're lucky enough to be in one of them you may soon get your datacomm gear :-) Sorry if this all sounds like a lot of gripe and blatant advertising. It's just that when Jim said "The problem is they haven't been developed yet" I felt I had to point out that there's a difference between "doesn't exist" and "isn't available in the U.S.". I *know* for a fact that our equipment is beeing installed in Mexico City. But how do you sell telecom equipment on a market where everybody still believes in their hearts that AT&T is the best while spending half the bandwidth of comp.dcom.telecom arguing that Sprint is better... :-) Disclaimer: I DO work for an Ericsson subsidiary but that doesn't mean I have any say-so.

Well, in your words, yes and no. In the case of SXS, they had to add converters, UNLESS they (notably GTE) used directorization. Then the tone receivers were imbedded in the equipment used on everyone's line. And it was impossible to turn off the tone capability. In the case of crossbar, they had to use the Teltone or Mitel converters (the Mitels were much better; they weren't tone to pulse, but rather tone to 'OR lanquage--2 of 7' and worked instantaneously). As you said, it was usually more cost effective to equip all ORs with converters, even though in the early days they did try to shuttle all non-TT-paying customers to non-equipped registers. But even that is no longer the case. Now they use CONTAC, an adjunct to provide equal access. Since the customer dials into the CONTAC, which is inherently TT-capable, you have to consider that TT is now imbedded in crossbar. In fact, CONTAC has a difficult time dealing with rotary and must receive pulses within the range of 9 to 12 PPS, or it will bomb. No 20 PPS for all those speed freaks that wanted to avoid TT. ALL electronic switches (including all permutations of ESS) have embedded tone receivers. >Can a PSC (or would a BOC want their PSC) to require a >different billing reate for (potentially) each CO? Yikes. Wouldn't that be a hoot? If the cost of your phone was linked to the actual cost of maintaining your CO switch, you would pay more for more antiquated service.

Not generally true. When the forwarded call supervises (is answered) then the forwarded phone will pass another call. And so on. The reason this was done (they used to forward any number of calls, regardless of supervision status) was to prevent forwarding loops. Try it; place a call to your forwarded number and when it answers, place another--it should forward as well. An exception to this is RCF. When you set up Remote Call Forwarding (a number that you don't even get a pair for, they just forward it for you to a number of your choosing), they ask you to specify how many "forwards" are to be allowed. This number should corespond to the number of lines available at location that is receiving the calls. John Higdon | P. O.

DOV (Data Over Voice) is a techniqiue that uses a single pair of wires that permits both data and voice on a line simultaneously. The data portion of the service is modulated at a higher frequency outsied of the normal voice conversation. For example, the voice conversation is at 300-4000 Hz (approx) and the data would be sent at 40Khz on the receive side and 80Khz on the transmit side. Because of the frequencies involved, the operating distances between 2 DOV units is usually less than 10,000 feet. DOV units are connected similar to a modem with a TESLSET jack and a TELCO LINE jack plus power.

This came up like this: We have a very funny kind of a problem with a Bell Technologies multi-RS-232 card. It's pretty late and we should try to get the machine and the card to the customer in the morning, of course in a fully operational status. The people who delivered this card to us are not at work at this time (not surprising, it being 1AM!). However, Bell Technologies has a customer help line number on their manual. On the forlorn hope that they have seen this problem before, we dial them. We get an answering machine saying they no longer are Bell Technologies, but a part of Intel Corp. AND THEY ONLY GIVE A 1-800 NUMBER ! We of course cannot call this number from Europe. After some messing around with Finnish outlands directory assist and American directory assistance operators, we are told: a) one cannot direct-dial a US directory assistance (areacode + 555 1212) from outside the United States (we tried). Why ? a) A 1-800 number cannot be traced back to the owner's "real" number, since there is no 1-800 directory assistance. True or false ? b) There are no services which we could call who could make us a almost-free (for them) call to a 1-800 number, while charging us for this service. Really, no-one has thought of this great business opportunity ? Finally, I called a good friend of mine in the US and had him call the Intel 1-800 and ask what their "real" number is. THEY REFUSED TO TELL THIS, SINCE THE NUMBER WAS "INTERNAL" EVEN AFTER HE EXPLAINED WHAT THE SITUATION WAS ! What they did give him was two numbers to the UK and Finland Intel offices.

The cause is L.A.'s "voracious" appetite for new technology -- cellular telephones, pagers, facsimile machines, and modems. "Simply put, we are running out of telephone numbers," said Dominic Gomez, Pacific Bell area vice president. This marks the first time demand for technology has been more important than population growth in the introduction of a new code. "It looks like we use this technology more intensively here in L.A. than in New York," said Larry Cox, a spokesman for GTE California. In 310 will be the coastal areas -- from the Ventura county line on the west to Long Beach on the south -- Westwood (UCLA), Beverly Hills, and South Central L.A. Downtown L.A. and Hollywood will remain in 213. 213 will border 310 at La Cienega Blvd. on the west, El Segundo Blvd. on the south, and 818 on the north & east. Small parts of Culver City and Beverly Hills will be split between 213 and 310; 213-255, -257, -258, and -852 won't become 310. "They" tried to divide 213 so that the two pieces would grow at similar rates. 310 was chosen because seven of the nine area codes available already were assigned as prefixes in 213, leaving 210 and 310 -- and they judged 310 was easier to distinguish from 213. There will be the usual three-month grace period between Feb. 1 and May 1, 1992, when phone calls to former 213 prefixes still will go through. A. R.

They are offering a new program, Empire 750, designed for people who call mostly within New York State. Their rates to anywhere within the state are $.13/min daytime and $.11/min evenings and nights. These are significantly cheaper than AT&T's intrastate rates. They are further sweetening the offer by discounting the first month's bill by 50%, switching you over for free, and switching you back after 60 days if you are not satisfied.

Northern 3CL Cord Boards! I'm looking for some. Need them desperately. We've chased down every source we can think of and have come up absolutely dry so far. Any leads (pun intended) anyone can give me, no matter how tenuous, will be greatly appreciated. Since alternative solutions to my problem are also quite acceptable, here's my problem. We are relocating all of our operator positions to another city. Most of the positions are TOPS or TOPS/MP running off our DMS-200 toll switches so those present no problems. However, we have some services that are inconvenient to do on a TOPS position (tie up a position for too long), would require extensive (ie: expen$ive) mods to TOPS, or are just flat impossible to do on TOPS in any useful fashion in any reasonable time frame. The service giving us the worst fits is General Mobile Telephone Service (GMTS). And we have _lots_ of GMTS all over the province and it isn't likely to go away any time soon. So far it appears that there really isn't any other convenient way to provide GMTS service than with a cord board because of its nature, and that's the way we are doing it right now. The characteristic that is the killer is the requirement for a "revertive calling" capability. For those who don't understand "revertive calling" (I didn't until a couple of weeks ago, and barely do even now ), an example may serve best. When a GMTS mobile wishes to make a call, s/he calls the mobile operator to set up the call. At the time the calling mobile places the call, they may say something like "George is out at the well-site and probably won't be able to answer right away so let it ring for awhile.". The operator plugs into the trunk associated with the channel the called mobile should be on and then she will let the thing ring for up to 3 minutes (mobile users _are_ quite frequently unable to answer in much less time than that, and mobile phones are usually wired to make the horn beep when the phone rings). If there is no answer, the calling mobile may then say something like, "Well, George may be over on the other channel .. could you please try that one." (We have many areas where there are as many as 4 channels available so you can iterate this last scenario up to four times!) Of course if the operator had to actually sit there and listen to the silly phone ring for 3 minutes each time through the loop, s/he wouldn't get a heck of a lot done, right?! Which is where the cord boards are so well suited to this task. While the phone is ringing, s/he can go on and handle other calls and simply plug into the one that s/he left ringing periodically to see what's happening. A good mobile operator can have some number of calls on the go at any one time ....[ ....and most importantly, ALL OF THOSE CALLS _STAY_ AT THAT POSITION so s/he can manage them all and doesn't lose any of them. And _there's_ the flaw with most of the other possibilities we've looked at. With any ACD- or PBX-based alternative we have looked at, you can't keep the call at that position without staying "plugged into" it, and in most cases you can't keep it there under any circumstances. In most cases with the "agent" positions on ACDs and PBXs, as soon as you set up the outgoing loop, the operator is dropped out of the call automatically, with no way to monitor progress or get the call back. In the few cases where the operator can hold the call at that position, they can only do it by staying hooked into the call, making it impossible to do anything else for the entire duration of the call, which could be more than 10 minutes (see above). Why would she have to stay hooked in for the entire duration, even when the call is connected to the called party? Well, the billing on these calls is done with manual tickets so the operator is also timing the call(s) and needs to know when they're finished. All of the ACDs and PBXs we have looked at so far either have no "billing" capability at all, or the "billing" system is only looking at "lines" and not "trunks" (the GMTS channels are all coming and going on "trunks"), and/or comes up way short in some other area(s) that makes it unusable. So if anyone knows of a system that can have "trunks" connected to it and has operator or "agent" positions that will handle multiple simultaneous calls at each position and let the operator keep the call at that position (with a light or some other indication that the call is still present there) without having to stay plugged into the call so s/he can handle other calls concurrently, I would be overjoyed to hear about it. And if you actually sell a product that will do what I need, so much the better!! Otherwise, keep those leads on where I can get some Northern 3CL cord boards coming in....please!!

This is available at least to certain US customers with Centrex, Centron, or single line service provided that service is off an appropriate switch (1AESS, 5ESS and, I believe NT switches, running the appropriate generic) and provided the voice mail system sends the right signals to the switch (if you get stutter dial-tone, it probably does). AT&T (I think) came up with this service a couple of years ago. In general its called "Message Service System" and includes "The Bulk Calling Line Message Service", "Individual Calling Line Message Service", "The Visual Message Waiting Indication Service", and "Message Waiting Indication via the I/O Channel for Bulk Calling Line Message Service". The specifications and message formats are described in an AT&T Technical Description, CIR 231-099-022TD (the copy I'm looking at is labeled "Issue 3", and dated February, 1987). As far as "turning on the light" goes, the voice mail provider sends a request to the switch which tells it to provide stutter dial-tone, and/or send a message over the customer's line (using FSK signalling) to alert a "light box" which is bridged on the line at the customer's premise. Messages are only sent while the phone is on-hook or during the silent interval of ringing (latter case I suppose for calling number ID). AT&T (and perhaps others) sells a "light box receiver" and a telephone equipped with the equivalent circuitry. I seem to have tossed the flyer I had so I don't recall the model numbers but as I recall the light box lists for around $50, the phone with the light for a few dollars more. I've never tried to buy one. I suppose you could start with your friendly neighborhood AT&T phone center. ------------------------------ Subject: Options With Cellular Phones Organization: Penn State University Date: Thursday, 14 Dec 1989 11:32:38 EST From: Mark Solsman I am in the same boat as the rest, I would like a cellular telephone in my car.

If you know the name of the company and the city it's in, you should be able to call your own country's international directory assistance number in order to get the regular listed directory number of the company (which may or may not be answered by the same people who answer the 800 number). Although some 800 numbers have a corresponding regular number, this is not always the case. Historically, when there was one phone company, 800 service was provided by routing the 800 number to a local central office. However, depending on the destination, the translation may have been to a dialable number or it may have been to a completely fictitious number which could not be reached except with the 800 number. Even in the cases where there was a real number, in the old days it was contrary to the tariffs to dial it, because the old-style billing on 800 Service was generated based on the usage to this number. If you called it as a regular number, the 800 customer still paid for the call (and you did, too), and the wrong amount of revenue was generated (a real big no-no for a regulated monopoly). Now that there are many long distance companies providing 800 service, it is more common for there to be a regular number and the billing is usually handled in a more rational manner. However, this still is not always the case. The 800 service may be provided on trunks directly from the long distance carrier, with no regular number associated with it, or the fictitious numbers may still be used, or the real numbers may "belong" to the long distance carrier, not to the customer. Even when there is a regular number, the customer may not wish it to be given out, so the long distance companies are not authorized to provide the translated number. And finally, 800 Service is pretty sophisticated. If I call 800 221-2000 to reach TWA Reservations, I will reach a different reservation center depending on what part of the country I'm calling from and what time of day it is. As Patrick already mentioned, there is 800 Directory Assistance, but giving out translated numbers is neither part of their job nor possible for the reasons stated above. >one cannot direct-dial a US directory assistance (areacode + 555 1212) >from outside the United States (we tried). Why ? This is not unique to the United States. I know of no case where customers in one country can call the directory assistance number in another country. Your own country's international directory assistance operator should be able to provide you any information the NPA+555-1212 operator could provide. The reason? Mainly because CCITT recommendations suggest that local operators should handle international directory assistance calls. This is done to ensure that only "trained" persons are on the line dealing with a possible language barrier, and to ensure that the information is presented in the CCITT approved format. (Whether operators are really trained to do this or not is another story. See my article in V9#543.) Also, your local telephone company or PTT may not be willing to spend money on international circuits being used for a service that cannot be charged at the full international call rate -- and many European countries will have a large set of foreign directories in their own international directory assistance bureau to use rather than making the call. >There are no services which we could call who could make us a almost-free >(for them) call to a 1-800 number, while charging us for this service. I've seen ads in some airline magazines for companies which do provide services similar to this. In fact, they provide local or toll-free numbers in many European countries that you can call and be connected to their message center, where they will connect calls, relay messages and so forth. Maybe someone remembers the name of one of these companies. I don't think their service is cheap. >Finally, I called a good friend of mine in the US and had him call the >Intel 1-800 and ask what their "real" number is. THEY REFUSED TO TELL >THIS, SINCE THE NUMBER WAS "INTERNAL" EVEN AFTER HE EXPLAINED WHAT THE >SITUATION WAS! Well, now you're just dealing with a person whose ability to handle a customer located outside the U.S. is less than satisfactory. If this customer service department is not willing to give out the number for their local switchboard, then there's not much else we can say about it.

This topic, of course, has been the subject of hot debate amongst telco and networking techies, not to mention savvy venture capitalists, for the past year at least. There is definitely *not* yet a consensus. I am of the "sooner" frame of mind. With the advent of FDDI, SONET, and other high-bandwidth fiber technologies, coupled with a decreasing premium for the cost of installing fiber, there is bound to be a move on the part of *all* common information carriers to wire everything new with fiber. This will, IMHO, cause an upsurge in demand on the part of business and residential consumers, and that resultant demand will push providers into rewiring the rest of the plant with fiber. The bigger question is *who* is going to do the wiring. Will it be TV cable companies, local telcos, or some other innovative entity that is out there on the fringes right now, waiting for the cashflow equations to work out right? The "50 Megabit Living Room" that the folks at the Media Lab have been talking about will be here sooner than most think.

PacTel is simply doing the usual pressure-job on the courts. Under the judicially-imposed regulations (i.e., the consent decree's a settlement to an antitrust suit, and implies previous guilt), "Bell" companies are allowed to have monopolies on local telephone service, but are not allowed to manufacture or own information providers. They have to buy their goods from the free market (what's that, they wonder?). Indeed Naason Sanches is allowed to have information services, available by phone. What PacTel isn't allowed to do is sell the information. They can sell the access to third parties who provide the information. But Bells are common carriers, who carry information for a price, and not information providers. The court has ruled, in effect, that if they were to be both, they'd have too much clout to compete with other information providers. If they really guaranteed fairness, they'd probably be given more leeway. (The FCC has relaxed its rules, but the court is now the limiting factor.) It takes time for a monopoly to learn to compete fairly. fred Disclaimer: I speak for me.

I've also lived in the NW (in Southern Oregon 'til recently) all of my life, but I remember when 411 did work. And when it stopped working.

My memory is hazy, as this was when I was "just a kid," but I think you could dial neighboring prefixes using just the last digit, as well. Anyway, my best guess is that both of these things stopped working sometime in the late 1960's. I remember getting a recording that reminded you to dial "459" when you'd just dialed "9", along with my parents receiving mailed announcements warning of the cutover.

This is just silly. There are five cases: A) Call is unidentified, "Number refused by caller" B) Call is unidentified, "Out of area, number not available" C) Call is identified, and I (the callEE) know the number and like it. D) Call is identified, and I know the number and dislike it. E) Call is identified and I don't know whose number it is. Given that, I can totally ignore categories A and D, always answer category C and route B and E to an answering machine for screening and possible answering. You might choose a different selection. I might change the selections depending on whether I am going to be awake or not. But that is certainly an effective new feature. >It gives plenty of ABUSE to people compiling information and >selling it. That's why selective blocking by the callER is a requirement in my view. It must be possible to CHOOSE whether you will give out your number. If it's an emergency, I think the caller would not be so foolish as to block the calling number. In any case, I would arrange to give a message "I don't take unidentified calls" when I get such a call. Then the caller could redial from an unblocked phone if it were REALLY necessary. (I don't expect this case to arise in practice, but that's how I would handle it if it did. You might choose some other option. It's a free country.) Bob Clements, K1BC, clements@bbn.com ------------------------------ From: David Robbins Subject: Re: Speech on Telephone Privacy Date: 12 Dec 89 17:05:21 GMT Organization: GTE Laboratories, Inc., Waltham, MA I find it faintly amusing that one aspect of Caller ID is regularly ignored in the midst of all the heat it periodically generates; Caller ID is in fact nothing of the sort: it identifies the *telephone line* from which the call originated, but says nothing reliable about the *person* who originated the call. If you assume that Caller ID will tell you who is calling, you will at least occasionally be surprised. You really can never be 100% confident that you know who is calling from the number that Caller ID displays: there is always the possibility that someone has tapped into someone else's line to make their call. For those of you who will rely upon Caller ID to, in effect, tell you whether or how to answer the call: If I call you from a friend's house, or from a pay phone, will you refuse to answer the call because you don't recognize the number I'm calling from? How can you ever be sure that a call coming in from a number you don't recognize is a call you can safely ignore? Those of us (myself included) who presently have *unpublished* directory numbers are *paying* the telephone company to refuse to disclose our numbers to the *public*. We are allowed to choose whether and to whom to disclose the numbers, and we are *never* *forced* to disclose the number as a consequence of our using the telephone. While it is true that our number is known to the local telco and the LD carrier, we have some expectation as a result of past and present practice that the number will not be given or sold to the general public. My number has been unpublished for quite a few years, and it has yet to fall into the hands of telemarketers. I don't call the 900 sleazebags, so they won't get my number. I have no doubt that a resourceful telemarketer could, with sufficient expenditure of effort, obtain my unpublished number -- it's not exactly classified TOP SECRET. But the whole idea of unpublished numbers is to give the customer a certain level of control over the disclosure of the number. Caller ID does, in fact, change that, and does so to a degree I am personally uncomfortable with. The bottom line is that Caller ID is being oversold -- it promises something that it in fact cannot deliver, namely identification of the *person* who is calling (why do you think they call it *Caller* ID?) -- and it takes something away from those of us who pay for an unpublished number. The more I think about it, the less value I can see in having Caller ID. What on earth would I do with it? ------------------------------ From: Mark Robert Smith Subject: Re: Dumb Question on Caller*ID Date: 14 Dec 89 15:57:37 GMT Organization: Rutgers - The Police State of New Jersey The caller ID box I have will hold 10 calls in it's memory. When a call comes in, it displays the number for about 10-20 seconds, then the display reads "CALL" until you actually review the numbers later. To delete a call, you hit the delete key twice. To review calls, you hit the review key, which cycles you back in time call-by-call. The first time you cycle through a given call, a little "NEW" indicator appears. To see the time and date of the call, you hit the Time-And-Date key. Calls remain on the box until you delete them, or memory is full. When the memory if full, a new call will push the oldest call out of memory. If a given phone number calls you twice before you review, only the latest time and date is kept and a "REPEATED CALL" flag is activated. Note that if you have an old call with the same number, it is considered a separate call from the new one, and the repeated call flag is not activated. This way, if Aunt Grace keeps calling you, she doesn't bump all other calls out of memory. Any other questions?

The information is only transmitted once, in a single burst, after the first ring. I suppose that different display units act differently. Mine (AT&T logo, made by Colonial Data Systems) displays the number for about fifteen seconds after the first ring, whether or not I answer. > Do any of these displays remember the last "n" numbers shown, so if > you get a string of calls in rapid succession, you can look back > through the history of received numbers to locate, say, the third-last > caller's number?

Again, individual products may be different. Mine remembers the last 30 calling numbers, and the date/time for each. Note that I wrote "last 30 numbers" and not "last 30 calls". If the same number calls several times the same day, it is stored only once, with the most recent date/time, and with a notation that it was a repeat call. The date/time is sent by the CO and does not depend upon a local clock in the display unit. Push-buttons on the unit allow the user to scroll backward in time through the memory, and view the number, date/time, whether or not it was a repeat caller, a NEW notation if it hasn't previously been viewed in review mode. When I return to the office, the device lets me see who called, and when, while I was out. The answering machine also date/time stamps its messages, so it is easy to correlate them with the Caller*ID display. I can also correlate the display with messages taken by the answering service (they only pick up on the main line) but their wallclock is apparently less accurate then the answering machine! The notation OUT OF AREA is considered a calling number. It, too, shows up with the most recent date/time when I scroll back. It, too, shows RPT if more than one arrived the same day.

The description of the service was very complete (for an article that came out at least five years before the product itself): it even showed a picture of a telephone set with a tiny 10-digit LED (this is before LCD displays hit it big!) display where the number card usually goes. The text of the article explained what would happen with unlisted numbers: If you were called by a person whose number was unlisted, the display would show a numbered code (such as "A51033") which the telephone company, under court order or for their own investigations, could translate into the actual number. Years later, after the big breakup, New Jersey Bell actually does introduce the service, and this time the story is different. The company has decided that the right to know who is calling supersedes the right to keep your number secret. (I'll agree with that, particularly in the context that if I pay for Caller-ID service, I want just that. Peephole analogy and all.) I want to change the topic: I think that while Caller ID is an improvement over no identification at all, it doesn't really resolve the ACTUAL issue at hand: knowing who is at the other end of the phone. No matter how much effort we put into identifying the PHONE that a particular call comes from, we will never be able to solve certain problems: 1: If you are blocking/ignoring "unknown" caller ID's, you may not be able to get an emergency call from a person you know if they are using an "unknown" phone. 2: If you specifically block a particular number, you can't be sure that the next call from that phone isn't one that you want. If you block a pay phone because some creep is making prank phone calls, your daughter might decide to use that phone (which was at a highway rest stop) to tell you that she was just in an accident and needs help. 3: If you block specific numbers, like the creep calling from the pay phone, nothing stops the creep from moving to the next phone and trying again. The same goes for telemarketers with dozens of outgoing lines. In order to stop them, you'd have to block ALL calls from unknown numbers, which brings us back to problem #1. 4: Even if you DO happen to recognize the caller ID that flashes on your display, you have no idea WHO is calling you. An apparent (oh so obvious) fix to all these problems is to identify the CALLER, not the phone being used to make the call. In the UNIX world, we don't identify people by the TTY they're using, do we? We have usernames and passwords. Why not eventually implement this idea for the dial network as well? This would solve a host of problems... 1: Fixes 1-4 above. We can allow our example daughter to call us from any phone anywhere, even if we are blocking "unknown" calls. 2: A tremendous fix to the privacy problem. When placing a call, the use of a personal ID is OPTIONAL... If I don't want to voluntarily give away my identity, I don't dial a PID. I then take the risk that the number I am calling may not be accepting "anonymous" calls, of course. 3: Replaces calling cards; I can request that any call I place using my PID is billed to me regardless of where I call from. 4: Personal defaults: Your default long-distance company, for example, can apply to you even away from home if you use your PID. 5: Makes dozens of features that we've always wished for possible. For example, reverse call forwarding: Forward calls FROM my own phone to me HERE! I always thought it a stupid concept to have to forward my phone before I leave home, and not to be able to change/cancel the forwarding until I return. If I want to get my calls at a friend's house, I have to forward it before I leave, and for the duration of my trip, my friend gets any call intended for me, even though I'm not there yet! (And I would have to pay for this! No wonder I don't get this feature myself!) 6: Ultimately: Call placement to PEOPLE instead of LOCATIONS. ("I want to talk to my friend; I don't care where he is right now.") A minor extension to reverse call-forwarding. 7: Destination routing / forwarding based on the caller's ID. ("Send all calls to my answering machine EXCEPT for my stockbroker, who should get forwarded here immediately!") Solves the premier problem of call forwarding; having to pay for forwarding of "junk" calls. My answering machine will know not to answer calls from family/friends if I am home (so I will answer them myself). 8: Security and other authentication functions (good for data calls, lets my answering machine know it's OK to playback my messages, etc.) Being able to change passwords "online" would be a nice touch (a big gripe with telephone calling cards: too easy for someone to discover, too difficult to change if I suspect it has been compromised).

I made a phone call to JCS and received their literature, and in addition spoke to someone in sales. The portable phone is simply a half-duplex radio with touchtone pad and proper signaling to be used on either an IMTS/MTS phone system in the UHF/VHF services. The short antenna is not for 800 mhz, but is just one of the newer style short stubby antennas you see used on HT these days. For $2300 (I think that was the price), I would go cellular anyday, or if you are in an area that doesn't have cellular service, just get a 30 watt mobile, you'll probably be better off. My last IMTS phone I bought reconditioned for $300 with a one year warrantee.

[Moderator's Note: Enterprise and Zenith were the same difference. Some telcos used one name; other telcos used the other. These numbers were the granddaddy of 800 service. In mostly manual, pre-dial-direct times, companies offered Enterprise xxxx or Zenith xxxx numbers as a way to induce customers to call them. They were automatic reverse billing numbers, functioning just like 800 numbers do today. You would raise the operator, and ask for Enterprise xxxx. The operator would consult with Rate & Route to find the 'real' number (remember that phrase from the past few days here?), and she would connect the call. Getting permission from the called party to accept the charges was not necessary. Like 800 numbers today, the old fashioned style could be set up to accept local, regional, intrastate, interstate or international calls, or various combinations. Believe it or not, there are a few companies still listed in the Chicago phone book with Enterprise numbers, but they are few and far between. In the early 1970's, I had Enterprise 5479, which rang my office phone, WEbster 9-4600. The charges came on the regular long distance phone bill.

Last week, an associate ordered a simple 8KHz audio circuit from Pac*Bell, who promised an install date of 12/19. Today we learn that because the far end terminates in GTE territory (and GTE has expressed a total non-willingness to perform on this according to our Pac*Bell rep) we won't have the circuit until January 4. My experience with GTE in the past is that this is probably the first of many missed due dates to come. We all talk about whether GTE has this latest equipment or that, or that one-line residence POTS customers seem to be satisfied with their simple service, but it's the GTE *attitude* that is the major problem here. The impression here is that the people associated with GTE genuinely don't give a damn whether they provide useful service or not. When I checked into GTE rates, I was given a third degree regarding the purpose of my inquiry, whereas Pac*Bell cheerfully sent me a detailed brochure. It is truly amazing that GTE can screw up virtually everything it is involved with, and yet defenders seem to come out of the woodwork. I am convinced that even more than Pac*Bell (and I've certainly made no secret of how I feel about them), GTE has got to be the real ball and chain on the legs of telephonic progress in California.

There are many examples. 201 is being split, yet 609 its neighbor to the South in New Jersey is almost empty. 312 has just been split, yet 815 which used to surround 312 in Illinois has plenty of room. Similarly it was just announced that 213 would split into 213 and 310, yet 714 and 818 are hardly busting at the seams and 805 and 619 have plenty of room. On a related note, the 213 split is said to have occurred because of the growth of cellular and fax lines (and probably centrex and numbers which are used but not associated on a one to one basis with physical lines). It seems to me that rather than pass the cost of this split onto every individual in the country, that the cost should be born by those who are causing the trouble. Given the prevailing socialism for the rich and powerful, however, everyone will pay. Finally, the LA paper seemed to gloat over the fact that LA would be the first city with 3 area codes and 4 if you include 714 in Orange County. It obviously never appeared to the editor that NYC has 2 area codes and 5 if you count contiguous, metropolitan areas. 201 is right across the Hudson; 516 is on Long Island just past the city boundary. 914 includes Westchester County which is just North of the Bronx. Finally, 203 is in Conn. I can't remember for sure if it touches NYC; I seem to recall that Conn is only a few miles away from NYC. (Note: I do not believe that Orange County ever touches LA either). As far as I can tell, an extra area code just means more dialing; it is not great accomplishment. [ The minor geographical issues involved are not worth many follow-ups.

Read the actual NUMBERS behind the trials, announcements and PR BS. o While fiber may be getting cheaper vis-a-vis copper the terminal equipment isn't. How is the fiber going to support grammy's black 500 POTS set?. Lets see... a fiber network interface, a fiber mux, a fiber-to-copper converter, an ISDN Terminal Adapter... plus, of course an uninterruptable power source. o Market tests show that most of the general public is not as impressed as us techies by things like HDTV. How many people do you know have megabuck TVs connected to rabbit ears or tolerate third rate CATV systems? Check the history of Teletex services, bank-at-home and interactive video in the US. I wish it were not so, but I think that fiber-to-the-home or even its cousin fiber-to-the-curb are much more than 10 years away.

Who gets priority? >Is this a first-come/first-serve situation? There are actually plenty of FCC regulations to cover situations of this type. The general overview, as I understand it, works like this: Although FCC regulations even prohibit low-power (Part 49) stations from causing intentional interference to each other, it's very unlikely that they would get involved in such a case. One of the two stations would have to prove not only that the interference exists, but that the intent of the other party is malicious. Even if a formal complaint were filed with supporting information, the FCC's first act would usually be to suggest a peacable, voluntary coexistence (possibly by getting one of the stations to switch to a different frequency if possible). Beyond that, a civil suit would probably have to be filed to get any action. What, then, of the guy with the baby monitor next to his stereo? Nothing will probably happen to him, unless the neighbors decide to take him to court (where, if they can prove intentional interference, the FCC's regulations will be on their side). Many questions would be asked in such a case: Was the defendant using this setup for a legitimate purpose, or purely to harass and annoy? (Did he listen to the monitor's receiver 24 hours a day?) Was it actually necessary? Did either party consider alternate measures, such as a wired intercom, or remote (wired) speakers for the stereo? The cost of doing all this would most likely outweigh (by a few thousand times) the cost of a wired intercom. How many people bought a CB radio and gave up on it because of all the interference and noise? The baby monitor in this case would probably end up in the attic next to the CB.

In his book, you'll recall, the bad guys used *portables* to make their calls. Portable cellular phones transmit at a maximum of 0.6 watts and usually less to conserve battery life; it seems hard to believe that this would be detectable from space. The base sites use 50+ watts, so detecting them may be more feasible, although, it is commonplace to use directional transmit antennas, further complicating things. The whole situation is made worse by the pleathora of frequencies used and the variety of cell locations. When I read the book, I wondered why everyone went through the trouble of a satellite and supercomputer. After all, cellular calls still make use of land lines.

There are some places in the U.S. that are still using Cord Boards. Crown City Plating, Rosemead CA, used to have one - may still do. You can call them at (818) 444-9191 and ask. I once told them they would be happy with a Mitel, they scowled. They are a pretty high tech plater of plastics etc. Kinda funny to see an attendant (telephonist) sitting at a board in the eighties. But I digress. About five years ago when I was meeting with some British Telecom people from Martlesham, they told me that BT was still producing cord boards. So try giving BT a bash. Maybe a BT type will write in and give an address/number where these devices can be bought shiny and new. Some countries in Europe were still using cord boards in COs up till the seventies. I remember seeing a creaky old mahogany board in a Norwegian CO. Screwed to the mahogany top was a Touch Tone pad. Yup, you rang the operator and she dialled Oslo for you on the Touch Tone pad. So maybe some Europe telcos have warehouses of these things -- Cord boards, not TT pads. Now Northern Telecom U K has been selling switches into Europe, Africa and Asia where they have replaced cord boards. Maybe they have taken these things away as a trade in deal. Ask them if they have any, when they have stopped laughing maybe they will let you have them cheaply. NT UK Tel # (628) 33211.

The arguement is that a telephone number is not private because the telephone company, not the individual controls it. I suggest that the individual does not have significant control over much private information. Most people would agree that a Social Security Number is private, yet the individual has no control over it. The government assigns it; if they wished they could change it. Since some SSN's have been given out more than once, I suggest that the government has excercised that right. Most people would agree that a person's salary is private, yet most individual's cannot unilaterally change their salary.

And thank YOU for your comprehensive and throughly-thought-out pronouncement concerning Caller-ID. I'm an end user and I can think of plenty of uses. 1. When callers talk to my computerized answering machine, it can recognize their number and give them an appropriate outgoing message, or even a particular message that I have wanted to deliver to them. Unrecognized numbers would still go to a general recording. 2. I am on call and my answering machine can page me. With Caller-ID, the machine could page and insert the caller's number in my pager, eliminating a confusing and error-prone step in the paging process. 3. A list could be prepared of "hang-up calls". This would provide me with evidence of how effective my answering system is in encouraging clients to leave their pertinent information. Also, I could return calls from those retiscent to leave information. 4. Since I have irregular hours, I am frequently sleeping when the world at large is doing business. However, there are some people that I must speak to when they call, regardless. Caller-ID would help my machine to deal with that problem much more effectively than it does now. Believe it or not, I will concede that there are legitimate concerns about the implementation of Caller-ID. But I will not stand still for one second when short-sighted people catagorically dictate that they can't see any reason why we, the public, don't need something they don't like. John Higdon | P. O.

Yeah... everything except privacy.. :-( [PS, as an aside I'm curious: when did this notion that "answering the phone" was somehow related to "privacy" in the Constitutional sense? It seems totally bizarre to me. People keep talking about the "peephole" analogy, but the reality is very different: peepholes protect you from *physical* threat, and in some sense DO have to do with your privacy [since the person can see if you're dressed or not, or where the stereo is, or if your new copy of the heavy breathers journal is on the coffee table]. Answering the phone embraces no such threats --- it seems that asking who is calling and if you don't get an answer you like hanging up more than adequately protects your "privacy". Now, you can complain that your *peace* has been disturbed, and I totally agree, but the peephole analogy doesn't work there at all. IF the doorbell rings, you have to go figure out who is there ANYWAY [and if it is an otherwise undistinguished person, you'll STILL have to ask them who they are and what they want... just like answering the phone. [Unless your world is different than mine: no one is "ID"ed on my front porch... the very best I can do is only the crudest of physical guesses about who's there [thereby displaying all your latent fears and prejudices about which book-covers conceal real threats inside-the-book]. That stranger on the porch is as liable to be a new neighbor from the next block as another Jehovah's Witness as a person selling storm windows]. Accepting privacy threat (as I see it) of CID as the response to the breach of your *peace* sure seems like overreaction --- killing a fly with a sledgehammer. There are MUCH easier ways [IMHO] to effect some kind of effective screening of your incoming calls [probably better than CID could ever dream to be unless the CID-likers get their apparent wish and we go to a fully-electronically-tracked society]. When we should be up in arms about the abuses to our privacy *already* being done, it is astonishing that there are knowledgable folks seriously arguing that that we should have *less*. If anything, instead of lobbying my PUC to get CID available, I'd be fighting to get *tougher* laws to make it mucho mucho mucho harder to let **ANYONE** see the CID info. Oh well... sorry to flame on again on this long dead topic, but that turn of phrase: that to really "fix" the privacy problem we need *better* electronic tracking of us all really got to me... :-( /Bernie\ ------------------------------ From: "John H."

We can go from there directly to most campus networks or go to the SDS (Serial Data Switch) to get to others, including those off campus.

It goes like this: You make a call on the single line phone. It's busy, or doesn't answer, or you are otherwise in a hurry to check your machine. You hang up on the previous call for the length of time of a "flash", putting the first call on hold. You get (second) dialtone, dial "9", then dial your call. In the meantime, the hold timer has determined that your previous call has been on hold long enough, but can't do anything about it. Then you hang up on your answering machine. The switch now sees your idle line and rings you (hold callback) to remind you that you left a call on hold. When you answer, you get what ever junk was left from that first call.

Well, define "the public". If by "the public" you mean "any joe schmuck who can read", you're right. If you mean "anyone outside the telco or LD carrier", you're wrong. Any call through an IC, if that IC offers an ANI delivery service, and the called party subscribes to the ANI delivery service, results in your unpublished phone number being disclosed to the called party. Immediately. Irrevocably. Without any possibility of blocking on your part -- even if your local telco offers calling number delivery blocking, you've subscribed to it, and you've blocked CND on this call. Congratulations; you've just been forced to disclose your telephone number by using the telephone, and this has been going on for several years.

I've had it on my work phone for three months now. Yesterday I had some conversations with other people at Bellcore about it, and we talked about the value. I realized that in the three months I had not rejected any calls because I didn't want to talk to the person or didn't recognize the caller -- but that for the past week (while I've had the service temporarily turned off -- it's not really Caller*ID, but part of an experimental package of services we're playing with internally) I've missed it. It was not so much the ability to screen calls that I liked, but just the knowledge of who it was calling so I could prepare myself mentally for the call. If it was my boss, I'd be in a different frame of mind than if it was a drinking buddy... I just felt more comfortable answering the phone knowing in advance who I was going to be talking to -- even if it didn't overtly affect my behavior in answering the phone. If I could have CND, with the number able to be delivered from 80%+ of the phones in the US, with an expectation that no more than about 10% of callers would have blocking, I'd be willing to subscribe, and probably pay about $3 a month for it.

Date: 16 Dec 89 20:47:02 GMT Organization: AT&T-Bell Laboratories Here is one additional reply to the many others on AT&T's SLC(r) 96 Subscriber Loop Carrier System. SLC is a registered trademark of AT&T Technologies, Inc. As stated by others, the SLC 96 carrier system is a digital subscriber carrier system that provides for up to 96 subscriber channels, when fully equipped, between a central office terminal (COT) and a remote terminal (RT). The subscriber channels are pulse code modulated and then time division multiplexed into DS1 (1.544 Mb/s) type signals. The DS1 signals are then processed for transmission facilities. In addition to single and multiparty message telephone service, the system can provide coin service, voice-frequency special services, digital dataport service, and voice-data circuit switched digital capabilities. The system can operate in three modes: Mode I - Provides 96 dedicated lines over 4 T1 lines. Mode II - Concentrates groups of 48 lines onto 24 channels or 1 T1 line. Mode III - Provides 48 special service, coin, or dataport channels per system. The signals can be transported between the COT and RT electrically or optically at the DS1, DS2, or higher order optical rate. This system was introduced in the early '80's as an economical replacement to the single copper pairs that run from the line card in the exchange to each subscribers home. Since that time a number of other vendors have introduced similar systems to the SLC 96. Because what once took 96 pairs of wires now takes 5 pairs (4 service and 1 protection), this equipment is called a pair-gain system. There is a sucessor to SLC 96 called SLC Series 5. This new system is similar to its predecessor but it serves twice as many subscibers in the same space with less power. It also has many enhanced features over SLC 96. One of those features is the capability to replace those copper pairs that extend from the RT to the home with fiber optic cable. Mark L.

In each cellular market, there are two sets of channels. One set, the "B" set is supposedly for use by "the landline telephone company". This could be a Bell Company, or more correctly a subsidiary of the Regional holding company. For instance, Pacific Telesis is the holding company for both Pacific Bell (my friendly telephone company) and PacTel Cellular, the abomination in Los Angeles that extorts money from people under the guise of providing mobile telephone service. Oops, sorry. The other set, the "A" channels, are for an independent company, such as an RCC or paging company. Therefore, there can be a maximum of two carriers in any given market. The distinctions are somewhat arbitrary, however. In San Francisco the wireline provider is GTE, who has an insignificant share of the telephone subscribers in this area; the non-wireline provider is Cellular One, owned primarily by Pacific Telesis, the major telephone service provider in the Bay Area. > 2) What is all the hubbub about subscribing with a certain carrier? > What are the differences between different carriers? > What questions should I be asking to find the right carrier for me? Shopping for carriers is like shopping for anything else. Who provides the best coverage in the areas you intend to travel in? What pricing packages do they offer?

I say maximum because the unit does not always transmit at maximum power. Its output is under the direct control of the cellular system which will turn your transceiver's output power down to the lowest usable level to prevent it from interfering with other cells. Handhelds are limited to .6 watts. Power is not important. The design of the cellular system is much more significant. My handheld works just fine in this system with its 600 MW anywhere I go. > 4) How can I get my hands on a cell map? Unless you are an experienced RF engineer, a cell map won't tell you much.

If they were all on the proper frequency, the CO would respond with two short tone spurts. Now we use 1-571 through 1-577 followed by the last four of the calling number.

The problem with this "neat" breakdown -- telcos are information common carriers, therefore they can't be information providers -- is that the telcos also "own" information that they could potentially "sell". (Of course, the question of who really owns information is still very thorny...) Should you restrict the telcos from selling, say, online white pages service? If you do, the service is never going to be available -- no one else has the information to offer it. Should you make the telco give the service away?

It must be possible to CHOOSE whether you will give out your > number. Here's something I don't get. One argument against calling number delivery and/or in favor of calling number delivery blocking is the potential for abuse by the called party. The argument is essentially (and if I mistate it, please correct and not flame -- I'm really not trying to set up a straw man) "Called parties can abuse calling number delivery by using the calling number to compile customer lists, harass me by phone, sell my phone number to telemarketing companies, etc. Therefore, [calling number delivery shouldn't be permitted | I should be able to selectively block calling number delivery]." Like I said, I don't get this. There is potential for the service to be abused, therefore, the service should be shut off (or blockable). Isn't the problem (in this case, anyway) the *abuse* of the service, not the *existance* of the service? Wouldn't it make more sense to outlaw the abuse of caller information, whether delivered automatically or manually? If you call a mail order company, and the agent says "and may I have a phone number where you can be reached", and you give it to the agent, the potential for abuse exists. (Yes, you have the potential to "block" the "delivery" of the calling number in this case; some people may do this.) My point is, it seems somewhat of an overreaction (typical of a great many overreactions by the american public and "public servants" these days) to attempt to quell a potential abuse of technology by attempting to restrict the use of the technology. What's needed is not the outlawing of calling number delivery -- what's needed is a clear statement of policy about the (I seem to be dwelling on this a lot lately) ownership of information and the rights of parties to use or sell information that "belongs" to someone else.

So here is the Ken Levitt plan for ANI. 1. Every line should have a parameter set at the CO to indicate the default selection for that line. By default the ID will either be sent or not sent depending on this setting. There would be no charge to establish your default the first time when you install a new line. There would be a small charge to change your default setting. 2. There would be two special codes that could be entered prior to each call to force ANI on or off for that one call. 3. Calls that have ANI turned off at the source should be identified on the receiving end with some code different than the code used to indicate that ANI information is not available. 4. Subscribers should be able to request an alias ANI for each line. The alias would be a unique number with a special area code to indicate that it is not a real number. All calls from that line would transmit the alias number unless ANI is suppressed for that call. The alias system could also be used to transmit the main number for a location that has several lines. If such a system existed, I would want the following system installed at my home: 1. A programmable computer would check ANI on all incoming calls. 2. Based in the ANI information and the time of day, the call would be routed to one of the following: a. A real phone b. An answering machine c. A modem d. A FAX machine. 3. I would be able to reprogram the computer at any time to meet my needs at that point in time. I would also want the system to send all calls destined to the real phone to my answering machine after some specified number of rings. It would also be very nice to be able to pick up any extension in the house and enter a code to tell the computer to switch to some special program like "Do not disturb" which would force all calls to the answering machine. Some people say that calls from the police or a hospital should not be ignored because I have not listed them as calls that I want to take. This is the ultimate in "Big Brother Syndrome". It is my business and no one else's as to which calls I choose to take. There is no law on the books that requires me to talk to the police or a hospital if I have decided not to take calls at that time. I do not wish to be a slave to my telephone. I would be interested in knowing if anyone can find a flaw in my plan. Unless you believe that I should be forced to answer some calls, I don't think that anyone should have an objection to such a system.

This way, the caller ID feature can display a license number instead of a telephone number. Telephone solicitors would have to have an appropriate license. Your phone could be programmed to reject all calls from licenses of a certain class. Privacy of callers is maintained as there is no way to map a license onto a name or telephone number without the licensees prior consent. The receiver's privacy is maintained because no one can make a call without disclosing their license number. If you receive an obscene call, the license can be reported to authorities and the problem dealt with in an appropriate manner. In the meantime you have the ability to reject calls from that source. The key thing here is that one has a telephone number to receive calls and a license for making them. Most telephones would have both. One can imagine the license encoding several pieces of information, especially for commercial users: 1. owner id License owner 2. service type Licensed uses 3. telephone Sublicense for a particular line The service type can encode such things as: solicitation, computer communications, general business, emergency services, private residence, local only, operator, language preference. Use of a telephone for solicitation without an appropriate license would be against the law. Other license notations such as for language preference and computer use can be on a voluntary basis. If you get a line for your computer it will have a license indicating its use. Non-computer users can reject all such calls. There is some potential here for dealing with phone abusers in a way more lenient than taking away their service altogether. You can imagine various special services such as: -outgoing only service (no telephone number) -incoming only service (no license) -licenses that are rejected by default unless specifically enabled -license as phonecard (with extra password) not necessarily tied to a phone -automatic collect call approval -automatic routing based on language Alonzo Gariepy alonzo@microsoft ------------------------------ Reply-To: John Higdon Subject: Re: How Were Telephone Sounds Chosen?

Hasn't an organization the size of Duke University heard of intercept recordings? It's not at all surprising that people are confused by getting a reorder every time they do something wrong. A reorder conveys little useful information to the caller except the absolute assurance that the call isn't going through. Here in PacTelLand, tariffs forbid you, as a DID subscriber to simply have invalid numbers go to reorder. You MUST have an intercept recording, preferably with SIT. Pac*Bell (and GTE, although they're more used to it) got tired of having tons of "call fails" rack up on their network tally devices. Since the lines are monitored for busies, reorders, and SITs, a high number of reorders looks real bad. Even on the PBXs that I tend, I use the ARS to send wayward calls to various Pac*Bell intercept recordings, which are available in a convenient bank of non-supervising numbers.

This is their usual crock. This gives them no end of reprieve in providing services to the customer. A notable example: 976. Their excuse for not providing it in the area code for which they were responsible (805, 714) was that there were too many unresolved issues. In other words, let everyone else battle it out and do the pioneering, we'll sit back and just collect the money when it's cool.

There's a lot of similarity between some of the Northern Telecom systems and their small CO's....but you'll have to talk to their engineering people to confirm this.

That was back when DA (information) was free. Then sometime in the 1970s Pacific NW Bell filed for new tarrifs, saying that they had to employ too many operators and that their studies had shown that most folks were dialing 411 rather than look it up. So part of the change was, if they were going to charge for the service, they made it so you were at least aware of change by making it 1+ and just like dialing DA for parties outside the NPA, 555-1212.

[Well, since I've recently flamed John about his attitude, I guess I'd better act as an equal opportunity troublemaker...] Mr. Chairman, I heartily second gentleman's motion. GTE can and will screw up most anything, it would seem. GTE's personnel appear to be less qualified and less diligent in their efforts to serve the lowly ratepayers. In addition, they seems determined to hang on to monopoistic attitudes more suited to the 1950's than the next century. To be fair, anytime a service order affects more than one telco and/or carrier things slow down...and the mean time to repair goes up, too. I have seen the same problem John described occur time and time again when telco boundries are crossed...be they BOC, GTE, United, Contel, Centel, or other independant telco. What seems to set GTE apart, in my mind, is their attitude. All attempts to escalate problems, be they repair, missed due dates or any other matter, are met with stalling, bumbling, and excuses. The poor morale of many GTE employees seems to be part of the problem. I have another axe to grind with GTE, since I compete with them in equipment sales. They barrage the customer with "we are the phone co., buy from us 'cuz we can do it better" and then go out of their way to provide exceptional services as part of the sales (from both the regulated and deregulated services)....and neglect us normal ratepayers... I still have an off premise station from my office to house that cannot be used for data (even 1200 bps!) due to noise bursts. GTE cannot find the problem...they say they have replaced everything! This on a 6000' metellic circuit with only a repeater in the CO ! I first reported the problem in May after a thunderstorm...and I pay $64.00 per month for this? And they tell my customers that they will have less problems if they buy from the phone co? I still have to explain proper procedures on line polarity, identification and location routinely to GTE installers. GTE personnel WILL NOT mark or identify circuits/lines on their demarcation jacks 90% of the time! Its been how many years since FCC type-acceptance...and GTE personnel still do not know how to properly set up demarcation jacks? The only field people who do decent work for GTE, IMHO, are the contractors! All other decent GTE line personnel seem to leave, quit, get promoted to elsewhere or transfer! Now GTE knows how to perform...look at Mobilnet...they should give lessons to the rest of GTE. The sharpest GTE central office field engineer I know transferred from GTE Ohio telco operations to Mobilnet because his supervisors at the telco were only concerned with paperwork and procedures, not service to the customers. He was constantly in trouble for fixing things in the GTD-5 CO's that regional said weren't broken. Mobilnet actually encourages his efforts.......the effects of honest competition might just help the telcos, I think. I have literally dozens of stories in this same vein about GTE. I have far less horror stories about Ohio Bell, and I have more systems installed in OBT territory than GTE. This is more than just sour grapes from a competitor, really.... (I tend to get carried away on this subject...I even worked for GTE for two years...and quit in utter frustration) Then, again, there's Alltel (Mid-Continent Telephone)..and United Telephone of Ohio...IMHO, they are little better than GTE most of the time. I'm no fan of Ohio Bell, but if I judge by results, they are the most consistiently reliable and easy to deal with. Now lets talk about long distance carriers...and attitude... Macy M.

Organization: Segue Software, Cambridge MA Date: 18 Dec 89 14:47:41 EST (Mon) From: "John R. Levine" Enterprise numbers (known as WX numbers near Philadelphia, there'a another trivium for you) do offer one thing that 800 numbers or remote call forwarding don't -- very precise control of where you will accept calls from. For example, Pakistan Airlines has an Enterprise number that one can call from downtown Boston or East Boston (where the airport is) but from anywhere else you have to call their number in New York. The real utility of this is of course open to debate, but there it is. Does anyone know how much an Enterprise number costs? Can you still order them or are the existing ones grandfathered? One other thing. You call the local telco operator and ask for the Enterprise number, she puts the call through. I presume they use AT&T. Is there an equal access waiver? Regards, John Levine, johnl@esegue.segue.boston.ma.us, {spdcc|ima|lotus}!esegue!johnl [Moderator's Note: What you say about flexibility is not true. 800 numbers can be configured for local calls only; intrastate calls; interstate calls only from certain regions (the old 'band 1', 'band 2' ....'band 6' method of assigning numbers), or various combinations thereof. I think Enterprise service is grandfathered, and no longer available to new subscribers. Regards the placing of the call, my phone book says 'dial your long distance operator and pass the number'.....which leaves the question can MCI/Sprint/miscellaneous AOS types also handle Enterprise calls?

There are plenty of people *in* North America who cannot call American 800 numbers. Many of them are called Canadians.

Telenet's 9600 baud indials are supported with Microcom's AX/9624c modems. These modems are async/sync modems, with support for MNP classes up to 6. These classes are: (paraphrased from my AX/9624c manual) MNP Class 2: Utilizes asyc framing for data transmission. Actual throughput less than bps rate of modem. MNP Class 3: Utilizes syncronous framing techniques, removing the start and stop bits prior to transmission. Results in a (claimed) 20% increase in performance over MNP Class 2 service. Actual throughput may reach 2600 bps. MNP Class 4: Utilizes syncronous framing techniques, plus a redesigned packet header to reduce overhead. Class 4 includes Adaptive Packet Sizing, which adjusts the size of the data packets based on the quality of the telephone line. Actual throughput may reach 2900 bps. MNP Class 5: Provides data compression, allowing throuput at up to twice the connection speed. MNP Class 6: Utilizes half-duplex, fast-train high-speed reliable connections with other MNP Class 6 modems at speeds of 4800 to 9600 baud. Uses Universal Link Negotiation to connect with other MNP modems at the highest common speed. Uses Statistical Duplexing to adjust the line bandwidth (?) and data traffic flow during reliable connections. Unfortunately, the Microcom modems do not support the now-emerging standard V.32. Telenet is supporting 9600 baud indials in some of the larger cities (I used the Los Angeles, CA 9600 buad indial when I was there). In their usual style, Telenet would not commit to supporting the Microcom AX/9624c modems one a 9600 baud standard emerged. They also would not comment on plans for 9600 baud outdials. My experience with the AX/9624c has been pretty good (it was purchased specifically for a Telenet connection to an information service), but it sees more use in 2400 baud MNP Class 5 (4800 bps throughput). Every AX/9624c I have seen has tended to run very warm (even though it has an external power supply), but I haven't seen any adverse affects.

Mobilnet is my cellular provider and I will second that statement. They bent over backwards helping me solve a roaming problem with another provider--and it wasn't even their doing. Within my home area service is so good, I don't even think about it. Calls complete within two seconds, they stay up, and coverage seems flawless everywhere I go in the Bay Area (and that's using my .6 watt handheld). I have nothing but praise for Mobilnet. And I repeat: they should drop GTE from their name--it would help business, I'm sure. A fellow radio engineer recently dropped out of broadcasting to go to work for Mobilnet. He travels all over the country solving cell site coverage problems, recently in Hawaii. He says that it is an outstanding operation to work for, mainly because they really seem to be interested in providing first-cabin service. John Higdon | P. O.

To this day, there is not a 245-prefix in 818, probably to avoid confusion. In fact, if you dial 245-1234 from within 818, you get a recording "The number you have dialed is not in service in this area code". I hope this answers your question(s).

We couldn't find and way to disable this in the version of the switch they have. Jerry Durand jdurand@cup.portal.com ------------------------------ From: Cliff Coombs Subject: Calling Yourself?

Most dealers will sell you the unit they are getting the best spiff off of this week. Most of all shop around, have several different places show you the same unit, ask about where accesories for that unit may be purchased. You'ed be suprised how many companies sell just the phone, and can't even *ORDER* an extra antenna, or battery pack for it. Also, and I hate to company bash here, (except for GTE) especially since a representive of the company I am about to bash gave very good answers to your questions.. But... Motorola cellular customer service *sucks* *rocks*.. (whew, that felt good) Let me explain, I am the ideal cullular customer, I constantly run bills in the 500-800 minute a month range. I have sold several phones to associates of mine and they too run rather large bills. At the time I purchased my phone I shopped around and the general consenses was that Motorola made the best/most reliable phones. This may be quite true, my phone still functions just fine after well over 100,000 hours of time. But.. When I purchased this phone I was assured that it would take an adapter that would allow hands free communication in a car, (like a normal telephone speaker box) In the box with my phone was a brochure that has a picture of and about 1/2 dozen other options I could buy for it. Now then, this Christmas I was going to treat myself to a hands free adapter, I called the same people I purchased the phone up and had them order me one. They called back a few hours later and said that Motorola, NEVER MANUFACTURED THE HANDS-FREE ADAPTER FOR THIS PHONE. Needless to say I was a bit miffed over this and gave Motorola a call about it. The nice lady on the phone proceeded to explain to me that *they* didn't put that brochure in the box with the phone, the fact that it was sealed in the same plasic as the owners manual, in a sealed box, and it was pretty much obvious that it was the first time the box had been opened when the dealer pulled it from stock for me. Didn't seem to phase her one bit. Matter of fact, the *ONLY* thing she could do for me was sell me another phone for 4000.00 that WOULD do hands free in the car, of course that little option was a mere 1500.00 more. Oh yeah she also told me that I should *NEVER* buy a phone from a dealer since they obviously wouldn't know if the phone could support hands free. (I guess that must be right if they look at the brouchures that come in the box with the phone.) Well at 5500.00 dollars I can buy several portable phones from almost anywhere and most of those have hands free adapters for < 100.00. Anyway, now that I've vented my frustrations a bit, I will say that I have put this unit through h*ll and it still works like the day I bought it. So, technically the phone is great, just that Motorola doesn't know the meaning of the word's "customer service." Oh, yeah, I did write a very nice letter, including a photo-copy of the brochure, to several places inside of Motorola, if something interesting comes back I will be sure to follow up with it to Telecom.

I may have a red face over this one. You have to understand that I have had Commstar since 1981 (formerly Premiere--home Centrex) and sometimes forget that the custom calling features pricing for Commstar lines is different than for "stand-alone" lines. The price for practically any optional custom-calling feature is $5.00 to install and $2.00 per month. Call waiting, call forwarding, speed call, busy call forwarding, etc., etc. are all that price on Commstar. What you confronted was "real world" pricing of the feature. Sorry 'bout that. > I asked the business attendant what was the difference in the > services, and she claimed there were no differences, other than the > fact that busy-forwarding could forward to a business number. That > doesn't make a lot of sense to me, but I suppose they're just trying > to gouge the person that needs a personal and a business number > forwarded to each other. Are there a lot of those people? From a tariff standpoint the difference is significant. Hunting may only occur between lines with the same prefix, with the same class of service (business or residential; measured or unmeasured), billed to the same party. In mechanical offices, there are even additional restrictions concering the "hundreds" group. Busy forwarding effectively drops all of those restrictions. However, busy forwarding is not available from a mechanical office, either. When my business was considerably more complex than it is now, I had a salesman in Concord who had a listed number in my company's name. We had busy call forwarding on that number such that if it he didn't answer it within about 3 or 4 rings, it would forward to our 800 number in San Jose. It took them days to make it work, but it finally did. You can't do that with hunting. (Busy forwarding is actually busy/no answer forwarding, with the number of rings predetermined at installation.)

In southern California, it's not pockets but major infestations. A friend of mine who lives in that area once remarked that GTE controlled all the places in the LA Metro area that were worth living in. GTE handles the beach cities, and major areas more inland. Unfortunately, there's no easy way to tell in advance anymore.

G.722, A New CCITT Coding Standard for Digital Transmission of Wideband Audio Signals (IEEE Communications Magazine, v. 26, n. 1) describes a way to split audio input into two 4 khz bands using ADPCM coders. Audio data can be transmitted at 64, 56, or 48 kbits, thus allowing simultaneous transmission of other data. The system is targeted toward "audio- visual conferencing applications where one would like to approach the quality of face-to-face communication (p. 8)." My interest, is not the improvement in audio quality, but the use of data-speech multiplexing. This is projected in the article, for speaker identification or fax on the established connection. One of the major problems in teleconferencing is speaker selection, how to decide on the next speaker without using the normal cues one has when face-to-face. The Danish Telecommunication Research Labs. produced a pre-ISDN prototype with separate lines for audio, and speaker id and queuing data via modem, some years back. It turned out to be too complex for practical use. A version of my equal-time resolution rule was programmed into that system (Stodolsky, D. (1987). Dialogue management program for the Apple II computer. _Behavior Research Methods, Instruments, & Computers_, _19_, 483484.). This rule has been show to yield benefits in both emotional tone and group performance in controlled experiments. I would like to see the rule applied in one of these new ISDN conferencing systems, but its hard to get the attention of the equipment suppliers on this point. They typically resort to centralized control by a chairmen, without even the ability to run on "auto pilot", where people queue themselves up by pressing a "request" button or just by starting to talk with a voice-operated switch "pressing" the button for them. Central control of speakers was strongly disliked in the prototype system. In fact, all units were eventually rebuilt, so each one could be the "master" in a multi-unit conference. Chairmen management seemed a bit clumsy, even when the queuing was automatic and the chair just announced the name of the next speaker. From a psychological standpoint, fully distributed control is the only way to go, and it is quite feasible with ISDN, any takers? David S.

There is also satellite communications to ships at sea. Three country codes exist for ships: 871 = Atlantic, 872 = Pacific, & 873 = Indian ocean. Calls are placed just like a normal int'l call: e.g. (in the US) 011 871 1234567 # All ship numbers are seven digits (octal representation of a 21-bit ID number). When a ship moves from one ocean to another, it's number doesn't change, only it's `country code'. In the US, the ground stations for INMARSAT (as the system is known), are located just outside of Danbury, Conn. & Ventura, Calf. Other countries also have ground stations. The American stations are directly connected to the ISCs for AT&T, Teleglobe, & MCI. (Who says there is only one country code in North America?) Further technical info can be obtained out of the CCITT docs. I believe that Q.170 is gen'l info. Also one of the previous versions of the CCITT docs (I think it was the yellow books) had a supplement to the No. 5 signalling spec (Fascicle VI.2) showing some additional info. On an non-technical note -- a real problem for the system is that when someone calls the operator (AT&T Employee) & asks for a ship, they are normally connected with the high-seas operator (AT&T Run), not the INMARSAT system (non-AT&T).

Telecom readers, What John Levine was talking about is really true. I know a radio station in Connecticut which used enterprise numbers to determine which exchange it would accept incoming calls from on a talk show. "Today's exchange is Middletown", for example. They didn't give out their real number, so only if you called enterprise 9842 would the call go through. Incidentally the call letters for that station were WTIC, and their enterprise number spells out that call. 800 numbers don't provide the granularity this sort of thing offers. Also, the telephone companies probably won't let you change the 800 number's calling area every day like the Enterprise numbers would.

In particular, I'm curious about what you can get through them in the way of frequency response. My understanding at the moment is that T1 is delivered on a regular 4 wire connection to one's building. Are there equalization networks along the "subscriber loop" of a T1 that make it "better" than a LADS circuit? Here's the scenario: I'm wondering if I/others can connect a LADS circuit to an ARCnet board on a PC, running the Phil Karn (KA9Q) software, with the ARCnet-TCP/IP driver in place (don't worry, we're a non-commercial outfit) to get a TCP/IP connection between home and work. The 1 megabaud (nominal?) rate from the ARCnet board should be lower rate than a T1 at 1.544 megabaud; will it make it in terms of frequency response? If this setup would work, it would let everybody use relatively CHEAP interfaces and software to make a FAST connection. An old story: Back when 9600 baud modems were horribly expensive, we arranged a remote terminal on a LADS circuit for a customer in Arcata, CA. The "couplers" (not modems) that got purchased seemed to be transformer coupled, and mostly seemed to convert to/from some RZ coding scheme at a fixed baud rate (9600) onto the LADS line. The whole setup was horribly sensitive to electrical noise (changing the interior wiring that PacBell had done from silly "quad wire" (NOT twisted pair) to twisted pairs helped some, but it was still subject to garbage occasionally. Would current-loop couplers have been better for this 6 mile circuit? (Traditional sillyness, the offices were only 2 blocks apart, but the phone company would only make the connection into the office on the other side of town, and back out again) I notice that some other high-speed devices use RS422 (like microwave transmitters), but I've had better luck with current loop lines than differential or single-ended lines. At least in San Francisco, LADS circuits are extremely cheap, namely $200 initial installation and $18 a month, when I checked a couple of years ago.

The first time I was calling from California concerning my soon-to-be-established service in Illinois, and the only number I had was an 800 number that (naturally) only worked within the state of Illinois. Fortunately in that case I had a Champaign-Urbana telephone book which listed the general office number in area code 312. (They couldn't handle my request, but they did give me a different 800 number.) The second incident occurred when I needed to clear up a billing problem on my just-disconnected Pacific Bell service. I was now in Illinois. Pac*Bell (at least in the part of the Bay Area where I was living) had instituted a special 811 prefix for all of its office numbers. I guess that the goal was to route calls to the nearest office. Naturally, these 811-xxxx numbers didn't work long-distance. A call to directory assistance yielded the 811 number; however, after I explained my problem they gave me another number (with a different prefix but the same xxxx). (Perhaps the fact that it had something to do with money for them motivated the provision of this unlisted information.)

I don't think so. Accepting a call on an 800 line is equivalent to paying for it. These lines may be billed on a minutes-of-use basis, without regard for the source of the call. So if you did know the underlying non-800 number, it would be billed as an 800 call anyway. There are indeed overseas 800 numbers, but they're typically in the national equivalent of 800 service. Thus you can get a line in the US that answers to a UK 0800 service, and pay an appropriate international rate for minutes of use (around $100/hr from Europe). Of course you need a separate number from each country. The SAC 800 we dial in the US doesn't map across the puddle. (Not that it couldn't be force-fitted, but the billing systems in Europe would see a call to +1, and bill for it, even though the recipient was also paying.

Actually there are quite a lot of them, but the caller uses a number assigned in the country he's calling from. In the UK, for example, the numbers start with 0800, in France they start with 05 (and are called green numbers for some reason.) The same thing applies in reverse.

Billing is relatively secure. Each student is issued a Personal Security Code which must be entered on the phone before you can get an off-campus trunkline. This PSC is the source of all billing. Thus even roommates who share the same phone will receive separate bills. It's a little inconvenient having to dial 91 plus a seven-digit PSC followed by the number, but it saves a lot of hassles in billing later. The distributing frames in the dorm basements are locked, but there are always ways to get around that. However, there isn't much point, as you can't "listen in" to a digital signal, and you can't make a call w/o the PSC number. Before 1988, Columbia was on a Centrex system, and the panels for that were blatently exposed. You could walk into the phone closet of any floor or the dist. frame in the basement and play all the games you wanted with a test set. I don't think it was ever too widespread, though.

They are a 4 wire metalic connection with, if connected properly, sealing current on the line. Sealing current on LAD circuts is a relatively new item (couple of years) so not all have it, and if you don't get it converted. It cut our service calls from one per week to almost never. (And they did the conversion for free, just to save on their service calls) Ok, here is what it can do: Send a audio signal end to end, with about a 12Khz bandwidth. Why: transformers on both ends to trap the sealing current. In fact, they make special modems for LAD circuits. Those modems can do 19200 for about 1 mile, 9600 for about 3-4 and 1200 for about 12-20. In our case, we got 9600 to work pretty reliabably. There are strict standards as to what signals can be put on the line, to avoid cross talk with the other normal pairs in the cable plant. >My understanding at the moment is that T1 is delivered on a regular 4 >wire connection to one's building.

T1 can be distributed on metallic, if you put regenerators ever so often, and its not that far apart at T1 rates. 56KB can go farther without regen, but even at 56KB, you probably will need one to go 6 miles. Getting ARCnet to run is not too likely. Remember to run T1, you must run CSU's, and they are fixed rate. ===================================================================== Sydney S.

There is a discussion taking place in the newsgroup ca.general, which I presume you don't get, so I have forwarded the articles (my 2 among them) to you for use in Telecom. Michael C. Berch mcb@presto.ig.com / uunet!presto.ig.com!mcb ========== [Moderator's Note: Thanks for sending these along. First, the newspaper account which started the discussion, then the responses: PT] ========== The following article is from the Los Angeles Times, Wednesday, December 13, 1989, page A1. Running Out of Numbers, L.A. to Get 3rd Area Code by Paul Feldman Times Staff Writer Times staff writers John H. Lee and Jocelyn Stewart contributed to this report. The mathematics of life in the Los Angeles metropolis is about to become a bit more complicated. In a city where commutes already are defined by numerical sequences -- as in, take the 110 to the 10 to the 405, and if you hit the 101 you've gone too far -- an unprecedented third telephone area code is in the works, officials announced Tuesday. In February, 1992, the boundaries of area code 213, which only five years ago begat the 818 area code, will be split again, creating a U-shaped sector of 2.4 million telephone customers with a new 310 area code. The new district will include some of the city's priciest neighborhoods -- Beverly Hills, Malibu, Santa Monica and the Palos Verdes Peninsula. It also will serve more humble locales, such as Downey, Whittier, Compton and Lynwood. Downtown Los Angeles and some surrounding communities, such as Hollywood and Montebello, will remain within the 213 area code. At a joint press conference Tuesday, GTE California and Pacific Bell officials said the addition of a third area code is necessary because they simply are running out of phone numbers for Los Angeles. It will become the first U.S. city encompassing three area codes -- and those with a more metropolitan view of the Southland might count four codes, including Orange County's 714. The announcement reflects the region's booming economy and increasing reliance on new technology, such as fax machines and cellular phones, according to Dominic Gomez, Pacific Bell regional vice president. "This explosion in technology has exhausted our prefixes at a rate no one could have predicted," he said. The cost of calls between the 213 and 310 area codes will remain the same as before the split, officials said. Customers will retain their existing seven-digit numbers. Since the 818 code was introduced in the San Fernando and San Gabriel valleys in 1984, an additional 1.3 million telephone lines have been added within the 213 area code. Based on that rapid growth, officials said, the phone companies would have run out of numbers by the end of 1992. With the new 310 code, those who let their fingers do the walking are certain to get a bit more exercise. A caller one block east of La Cienega Boulevard who wants to ring a pizza shop a block west of the boulevard will now have to dial 11 numbers, as with any long-distance call. On the Westside, the rough dividing line between the 213 and 310 area codes will be La Cienega Boulevard, slicing West Hollywood in half and resulting in immediate howls of protest from community officials and business people. "This will have a serious impact on certain businesses in my city," said West Hollywood Mayor Abbe Land, who was not consulted before the announcement. "Now people will have to say, 'Oh, that business is on Fairfax and I'll have to dial one prefix,' or 'Oh, this is west of La Cienega, I'll have to dial another prefix.' That's unacceptable." Land, whose City Hall office will now be in a different area code than her home, said that the city of West Hollywood will explore possible legal action. Defending the decision, telephone company officials said the new boundaries are governed by technological considerations rather than political guidelines. Rather than relying on city borders, they based the new districts on telephone prefixes. "We looked at dozens of plans and there are no plans where some communities weren't impacted," said Pacific Bell media relations manager Kathleen Flynn. "This is the plan with the least amount of impact." One rejected alternative, officials said, would have kept Los Angeles International Airport and the Port of Los Angeles in the 213 area code. Growth patterns are such that such a split would have forced yet another new area code within 13 years, they said. With the plan announced Tuesday, officials said, Los Angeles will not run out of phone numbers again before the year 2015. The new division also reflects phone usage patterns, according to Stephanie Bradfield, GTE public affairs director. Los Angeles and Hollywood were kept together, she said, in part because of the large number of calls between the two communities. Bradfield warned against trying to read too much into the divisions: Creating a new status code was not the intent. "Where there were strong ties, we tried to keep communities together," she said. " . . . [But] this is basically a technical engineering decision, not a social engineering decision. The code cuts a wide swath through the entire community." The choice of 310 as the new area code was a matter of deduction. There were but nine remaining area codes available in the United States, telephone officials said. Seven of these duplicated existing prefixes within the 213 area code. That meant the choice boiled down to 310 or 210. Gomez of Pacific Bell said 310 won out because it was distinct from the existing 213 code. That the 210 code duplicated the numbers of the Foothill Freeway apparently was not a factor. The new 310 code, which will take effect Feb. 1, 1992, is being assigned to 2.4 million customers. That will leave 2.6 million in the 213 code. As when the 818 area code was introduced, phone subscribers will have a grace period in which they can use either code. In this case it will be three months. But that provided little consolation to some telephone customers when they heard of the change. "This will greatly confuse things," said Mitchell Ogas, manager of Sunset West Beauty Salon in West Hollywood. "You may be just down the street, but it will seem a world away with another area code. It will be much more complicated that with 818 . . . . I would think they would have broken it up by city boundaries." Several businesses on La Cienega Boulevard with two phone lines will now have one in each area code. This is because their telephones have different prefixes, one served by each area code. "This is going to be terrible. At Laffs R Us, we are not laughing today," said Susan Valerie, program director of a "comedy traffic school" on La Cienega. Among the few happy businesses contacted Tuesday were those that will get extra work printing new business cards, stationery or shop signs. "It will be an inconvenience for most businesses, except for printing," said Robert Davidson, a production manager at Printmasters in Los Angeles. "By the end of 1991, business will be booming. It will be great." Meanwhile, the city's top real estate brokers speculated that the changes may actually reduce the status sometimes connected with area codes. "It's going to fragment that," said Fred Sands, a well-known real estate executive. "You've got Beverly Hills sharing with San Pedro. They're worlds apart." Sands said that in the past he has heard people from Beverly Hills put down San Fernando Valley residents as "real 818s." "Perhaps," he said, "the area code won't signify as much as it did before." ========== >From: mcb@presto.IG.COM (Michael C. Berch) Organization: IntelliGenetics, Inc., Mountain View, Calif. USA Sigh.

When they went to split up 212 in New York, all the Brooklynites (and other people who moved out of 212) claimed it was discrimination -- that the 'lesser' people were kicked out of the area code and were being discriminated against by being forced into a second rate code. sheesh. Chuq Von Rospach <+> chuq@apple.com <+> [This is myself speaking] ========== >From: hoffman@mantaray.cs.ucla.edu (Jeffrey M. Hoffman) Excuse me, Michael, but as a taxpayer you should be more outraged at the amount of money be spent on Prop 103 litigation. However, there is merit to Abbe Land's argument--when NYC was split, 212 was retained in Manhattan and the Bronx, and 718 for Queens, Brooklyn and Staten Island. The business people in these boroughs were quite upset, because previously they could list their address as NY, NY (with the appropriate ZIP code) and have a 212 number. Thereby gaining the prestige of a NYC address without the cost of a Manhattan location. When 718 went into effect, these businesses could no longer "pretend" to be in Manhattan, because it would be clear from the phone number that they were in one of the less prestigous boroughs. Of course, they lost their case. However, NYC was split along county boundaries (each borough is really a county). In the present case, the phone company is trying to split up an incorporated city. This is particularly annoying since people tend to associate a single area code with a particular subdivision. For example, even though you live only two blocks from an area code change, that change occurs ON A CITY BOUNDARY. It is easy for one to remember that Sunnyvale is 408 and Mountain View is 415, but it would be a lot harder to know whether a particular phone number is for a location east or west of some random boulevard. Think of the confusion that will arise in the future if this practice is continued. I support Ms. Land's case. However, the phone company does have a point--technically, the phone system was set up before West Hollywood attained cityhood. This means that it was just an unincorporated area of LA with no "political" boundaries. La Cienega Avenue is a large street and was a logical division point for switching equipment, etc., but it now divides the city of West Hollywood and is no longer a "neat" way to subdivide LA area codes. jeff ========== >From: galcher@Apple.COM (Bill Galcher) Organization: Apple Computer Inc, Cupertino, CA Well, as it turns out, the above is not quite true either. I lived and worked in Sunnyvale for a number of years, and part of Sunnyvale is in (408) while other parts are in (415). The first/only time I believe this became a concern was when they actually cracked down on the area code usage. Up until 1982 (?), if you were in the 408 area code, you could dial a number in the 415 area code by just dialing the exchange WITHOUT the (415) at the beginning. When the 408 area code wanted to start using some of the same exchanges that were in 415, they started by giving you warning messages that "you had to dial 415 for that exchange and will no longer be able to use just the exhange after such-and-such date", then let the call go through. That caused a number of people to have to adjust their auto-dialers but did not otherwise cause a major fuss. Sheesh - it's just not that big a deal. So you have to buy new stationary. So you might have to get a foreign exchange number in the other area code. BFD. It's certainly not worth getting this bent out of shape about.

The people of California were stupid enough to enact an intitiative that was both unworkable and partially unconstitutional, and those adversely affected by it went to court and won their case. I would love to claim some sort of exemption from having to pay for the litigation by showing that I wasn't silly enough to vote for 103 in the first place, but unfortunately it doesn't work that way... > However, there is merit > to Abbe Land's argument--when NYC was split, 212 was retained in Manhattan > and the Bronx, and 718 for Queens, Brooklyn and Staten Island.

Do you think that firms have a property right in being able to attempt to mislead people about their address? I'm *real* impressed by that one. Furthermore, they weren't supposed to use "New York NY" as their post office address anyway; I remember reading that NYC was divided up into a number of so-called "Post Offices" (no correspondence with real Post Office buildings) where only Manhattan was "New York", Brooklyn, [The] Bronx, and Richmond used their borough names, and Queens was divided up into three or four "P.O.'s": Long Island City, Flushing, and Forest Hill among them. > occurs ON A CITY BOUNDARY.

Sheesh. All I can recommend is that you Angelinos change out of the fast lane for a while and mellow out a bit; you might enjoy life more. And as for those who suggested that I thought the way I did because the change doesn't affect me -- you should all know that 415 is being split even sooner than 213 -- my house in the East Bay will be moving to the new area code 510. Since hearing this news a few months ago, I have spent at least a good 20 or 30 seconds worrying about it. :-) Michael C.

The company had sought only a $239 million cut, saying it had higher labor costs after settling a strike. The PUC's Division of Ratepayer Advocates had called for a $504 million cut, saying Pacific Bell had made accounting changes that distorted its 1989 revenues. Sometime next year, the commission is also scheduled to order Pacific Bell and GTE to eliminate their current $1.20 monthly charge for touch-tone phone service and to expand toll-free local calling areas from eight to twelve miles. This is the first ruling by the PUC under the give-away program granted by the commissioners earlier this year. You remember--this is the best of both worlds system: Pac*Bell is allowed to compete against its own network customers, such as alarm companies, information providers and the like. To provide plenty of capital for their vulture pricing and undercutting, they are guaranteed an 11.5 percent rate of return PLUS an inflation factor from their captive regulated market.

A quick scenario: I had just finished a 16 hour shift at work, gone to the dentist, and had about 4 hours to sleep before going in for another 16 hour day. As my head hit the pillow I remembered that I had forgotten to turn off the ringers to the phones, and I didn't even want to consider getting up to turn them off, I dropped the handset of my trendline (fastened to the frame on the waterbed for convenience sake) to the floor. In what seemed a very short time later the phones started ringing. Even in my incoherent state I realized that I couldn't answer the phone when it was already off the hook!! What's a poor boy to do? Hang up he phone, curse myself for not turning off the ringers, and get up (slowly) and go to work. I can only think of a couple reasons the phones would ring, the switch wanted to alert me my phone was off the hook, or someone had asked the operator to "check the line".

For example, the 310 area code in Los Angeles could be assigned to all new exchanges regardless of where in the region they are located, or all cellular #'s in the LA/Orange County area, or all modem lines or fax lines, etc... If Los Angeles already has multiple area codes (confused ME the first time I spent lots of time there), why not simply assign codes by service instead of by geography. It might well be simpler to associate "310" with FAX, MODEM and CELLULAR than with a group of seaside towns. Of course this is all quite naive. This probably violates many conventions of switch setup, etc. I'm not even suggesting that I think there is a sociological problem with spliting area codes; just asking a dumb question!

Using a pay phone at a service station along the highway, she dialed 0 then the number and the phone went dead. She tried again and again. She finally reached an operator and found out that (a) the phone was owned by a private company (not AT&T), (b) collect calls could not be made, and (c) she could not be connected with an AT&T operator. o Another woman received hourly calls with the recorded message "The maximum dollar amount is exceeded by the number 4-4-4-4-4-4." The problem was traced to a pay phone at a local gas station with a full coin box. The phone was programmed to call someone when the coin box was full. Unfortunately, it was programmed with the wrong number. o For six months a woman had long distance calls to Mexico City on her bill. The phone company finally discovered that the woman's line was cross wired with a neighbor's line. The twist in the story was that the neighbor had recently moved into the house and did not realize it had TWO lines (the phone company had failed to disconnect the second line when the previous owner moved out). The neighbor's bill looked normal since most of his calls were on his primary line. Only when he used a secondary phone were the calls billed elsewhere. o One family had phones that rang three times then stopped. Friends said they called and let the phone ring 20 times and no one answered. "After extensive investigation [GTE] found an electronic glitch at a nearby central office."

The Central Texas Sysop Association has initiated a grass-roots experiment of one method of containing the costs of running a BBS. As many of you are already aware, SWBT (the phone company) is involved in a Public Utilities Commission proceeding with several sysops from the Houston area. The outcome of this proceeding may affect the expense of BBS operation by classing all BBS operations as non-residential customers. One of the peripheral expenses accompanying such a change would be an increase in the cost of optional services. In the instance of tone dialing, the differential is approximately ten-fold (from approx. 50 cents/month to approx. $5/month). Over the course of a year, discontinuing tone dial would offset approximately two months of the basic non-residential service. This makes it worthwhile to determine the impact on BBS operations if pulse dialing were adopted as "normal operations" for both BBS's and users. The experiment does not involve actual termination of tone dialing service, although that may prove to be a viable option. All that is necessary to participate in the experiment is to change your modem dialing string to use pulse dialing instead of tone dialing. In the case of Hayes-compatible modems this is simply to change from "ATDT" to "ATDP" as the dialing prefix command for your software. Please help us examine this alternative to taking our BBS's off line should they be re-interpreted to be non-residential. Again, here's when and how to participate: START: 00:01:00 January 1, 1990 FINISH: 23:59:00 January 31, 1990 CHANGE: dialing prefix to use Pulse Dial (ATDT to ATDP for Hayes-types) Thanks in advance for your assistance in this cost containment experiment.

[Exceptions: some single town independent phone companies.] Other 555 numbers are given for certain telco business related functions. Aside: the business office is reached via a number which requires a 1 prefix to dial, though no charges are ever recorded to that number. When I call it while the office is busy, the recording which greets the caller begins with a message to long distance operators that collect calls are always accepted. /JBL (*) Directory Assistance?

Dialing into the number directly, without using the 800 alias would result in no 800 billing. 800 billing is done in two ways: in the originating CO, as part of the AMA system; or in the carrier's tandem switch. AT&T still uses, for the most part, originating CO billing as a carry-over from the old days, while other carriers do their own billing in their own switches. Remember, many companies now offer 800 service, and they have no access to any data relating to the incoming calls on the POTS number that didn't go through their system. Also, many 800 service plans (like the one I have) depend on where the call originates from. A call to the ordinary POTS number would just not register. John Higdon | P. O.

The 800 line had dial tone, so I tried ANI, of course, and I got a legitimate Cambridge number on a normal Cambridge exchange.

If indeed you did call the underlying non-800 number you would get billed for this as a normal call, not as an 800 (toll free) call.

The old type used a dedicated line, provided by the local telco under an AT&T contract. It could be billed based on minutes of use, since ALL use was dialed to the 800 number. Nowadays, you can also get an 800 number pointed at a real number, and it's billed from the source end (by the LD carrier providing the 800 number) and not from the minutes of use at the destination. fred ------------------------------ Reply-To: John Higdon Subject: Re: Anyone Know of "Reserved" Suffix 0020 Date: 21 Dec 89 02:55:05 PST (Thu) From: John Higdon Steve 'No Squash' Forrette writes: > I noticed a couple of years ago in PacBell land in Northern CA that > the 0020 suffix in just about any prefix always went to a loud, > continuous tone, which has about a 1/2 sec gap every 15 secs or so. > This also seems to be the case in Washington State.

Let me put it this way: I work at the company which did virtually ALL the R&D on both the AXE COs and the MD110 PABXs. *I* don't have even an MD digital line, much less an ISDN one. >As a Volvo owner (a Japanese speaking one at that) I am saddened that >Ericssons aren't taking on the world with their TAs. You can only take >corporate conservatism so far. Of course Jim is right. There's something saddening about the way big companies are going about this business, Ericsson not excluded. (Don't let anyone at Management see this...) You see, while small compared to the dragons of the telecom world, Ericsson is still in many aspects an uncomfortably big corporation when it comes to introducing changes. The MD110 PABX is manufactured by one company division while the AXE exchanges are made by another one. Unfortunately, phones and TAs are considered "office equipment" and thus fall under the same division as the PABXes. The sales people over there are utterly convinced that "ISDN can never be a success because they use 4-wire installations which must obviously be twice as expensive as ordinary ones". Needless to say, the Ericsson-specific (digital) feature-phones and TAs available for MD110 use 2-wire installations... ("bog-standard" to use Jim's words.) But all is not lost yet. I forwarded the message that "there are no TAs for sale in the US" to some appropriate people who immediately started sprouting little $$-symbols in their eyes in the best possible Scrooge MacDuck-style. We've made a HUGE investment in R&D on these buggers and every sale would be a help in cutting the losses! The problem preventing an immediate introduction is that the entire U.S. ISDN spec is "bog-standard", i.e. U.S.A. has chosen to specify a different method of rate adaption than the rest of the world and there are other "sublte" differences too. Some of them are fairly easily overcome - like the protocol differences I mentioned in my previous posting - while others would need major re-designs (or at least program changes in several micro- processors). I wasn't aware of that last part until I asked around a bit. Sorry. But I must ask a question to the net, U.S. readers in particular: I know for a fact (= I was there when it happened!) that Ericsson has been approached by one of *the* major Japanese electronics manufacturers (no, I'm NOT going to say which one - I'm far out on a limb as it is already!) which wanted to sell a line of ISDN phones with built-in TA functions. Essentially a small feature-phone with a V.24, X.21 or (I think, but memory is vague) X.25 connector. We tried it and found that with minor changes in CO software it could be used with our CO (remember I said our implementation is *very* close to the international standard. We like to think it's *the* closest one on the market at present!). Now, the price tags on these phones were rather persuasive - I think they'd be a success on the U.S. market at once if they were released.

I'm not sure if Marketing has used the same name in the U.S, but it's currently beeing installed at MIT, so I know it's available there. It uses a proprietary (sp?) 2B+D 2-wire interface for feature-phones which provides "ISDN-like" facilities but (unfortunately) so far in a non-standard way.

You either give out your number or you have have a pseudo number that does the same as a license. You can choose to have your number revealed (a convenience to both caller and receiver) on a per call basis.

There are lots of differences between US POTS and Euro-aussie POTS. For example we use 1.544 Mbps T1 and mu-255 PCM encoding instead of 2.048 Mbps E1 and A-low encoding. ISDN is a lot less different. There is no US rule for rate adaptation, since that's entirely transparent to the network. We have this system here, "competition", which basically says that the telco's fist stops at the customer's face, at the demarcation jack (reference point U). Rate adaptation occurs at a higher layer, so the telco has no say. The manufacturers here (especially AT&T and IBM) tend to favor the HDLC-based rate adaptation technique found in CCITT V.120, which was developed here. Some European-based vendors prefer the older bit-bashed technique found in V.110. And Northern Telecom has its own non-standard T-link which is fairly well established in the field. As long as the customer matches both ends, it'll work. The middle (network) needn't care. Hayes uses V.120, if I recall. >But I must ask a question to the net, U.S. readers in particular: I >know for a fact (= I was there when it happened!) that Ericsson has >been approached by one of *the* major Japanese electronics >manufacturers (no, I'm NOT going to say which one - I'm far out on a >limb as it is already!) which wanted to sell a line of ISDN phones >with built-in TA functions.

Most terminal-host connectivity is within the building (local area). ISDN, no matter how you slice it, costs more for this than a LAN with terminal servers. And the terminal servers tend to offer more flexibility, features, etc. Better, faster, cheaper. Pick three. So why waste ISDN by putting it on the desktop? Yes, I remember the early "integrated voice/data PBX" days, and helped put a rack of PBX data modules next to a VAX. Ugly, costly, and happily abandoned to the dregs of history. ISDN's strength in the data world is when you go beyond the LAN. ISDN to the home, or ISDN between locations. It makes a great modem replacement. But who in their right mind uses modems to dial down the hall? ISDN voice/data phones are about as useful as phones with built-in V.22bis modems: No reason not to put a phone on a modem, but not a mass market item. Fred R.

(I know from personal experience that the answer is either "sometimes" or "no", for I worked somewhere where it wasn't.) If that is the reason that a company wouldn't want to give out the underlying phone number of its 800 indial, surely they have other incoming lines on which suppliers, local business contacts, and employees' families can call them without their paying to receive the calls. It's very poor business practice to tell a potential customer that they refuse to talk by telephone with people in his or her location and that he or she must deal with them through the mail. Perhaps the question to them should not be "What's the true local phone number underlying your inward WATS service?" but rather "If someone who wants to buy from you can't dial your 800 number where (s)he is, is there another number (s)he can call your company on at his/her own expense?"

The service that provides the 800 customer with the callers number has nothing to do with CLASS and does not require CLASS capability at either the origin or the destination. It is simply the passing of the caller's number obtained via ordinary ANI to the end customer. This can be and is done in several ways. One is to simply send the info as a stream of MF or DTMF tones to equipment at the 800 subscriber's premises. A better way would be via a separate data line, and yes, ISDN could be used for this purpose. Whether or not it is required is simply a policy call by the long distance carrier. I would suspect that this service is only supplied to major customers and that anyone an individual might reach calling listed numbers will know nothing about it. To find anyone who is knowledgeable, at AT&T or anywhere else, will require a considerable amount of legwork. I was peripherally involved with a project that involved this and I know there was a major amount of channels that had to be gone through before anyone would talk about it. Again, the service has nothing to do with SS#7, CLASS, or any other relatively recent technology. When in use, there is no way to block your number from being transmitted. There are no tarrifs or regulations that would protect your privacy. And there is no way to know if it is being used. It doesn't matter where you call from--across town or across the country; it works just as well either way. As long as you are calling from a FGD compliant office (most of them are now) the 800 customer has *your* number. How's that grab all you privacy phreaks out there? :-) John Higdon | P. O.

Line after line, page after page, people rant on about how this could happen or that could happen. Is there no other aspect of telephony that has potential for abuse? What about junk calls in general? What about bunko scams that fleece the unwary? What about crank calls and threats? What about calls to detect whether someone is home by burglers? What about general harrasment? None of these involve Caller-ID. Maybe we shouldn't have telephones at all. Look at all the harm they cause. Silly, you say? Not half as silly as some of the arguments that have come down the line against Caller-ID. The IRS will learn nasty things about you. Credit agencies will do nasty things to your reputation. Husbands will march down to shelters and beat up their wives. Telemarketers will conspire to sell you things you don't want. Your cable company will keep a dossier on you and send you subliminal messages over the cable (no kidding!). All the mean, nasty people I am forced to call will find out my sacred unlisted number, causing my injury or death. I don't notice that in the areas of the country where Caller-ID is available that people are dropping like flies. It's a non-issue. It will eventually be universal (even here). But how many man-hours of discussion and rehash will have to go on first? Let's just get on with it. I routinely ride my bike at 65 on the freeway and survive, contrary to what people thought about going faster than 30 around the turn of the century. The concerns over Caller-ID sort of sound like that. microsoft!alonzo@uunet.uu.net writes: > This is a good plan and should be given real thought. Does anyone > know if there is some hidden agenda behind Caller-ID (conspiracies > everywhere...)? How many times does it have to be said; how loudly does it have to be yelled? Your number as a caller is circulated *all over the bloody network* all the time. People who do conspiracies *already have access to your number*. They don't need Caller-ID--THEY ALREADY HAVE YOUR NUMBER AND THERE IS NOTHING YOU CAN DO ABOUT IT. Period. When we discuss Caller-ID, we're talking about the info that is sent to you and me as lowly individual telephone subscribers. The big boys can get callers' numbers as much as they please. Caller-ID as a CLASS features offering simply provides a way for the *ordinary* telephone subscriber to have access to information about calls they receive, just as the big corporations, the government, and who knows who else, already have. Is this finally clear? Now, can we discuss the real ramifications of Caller-ID and leave out issues of privacy, conspiracy, marketing, the IRS, credit reporting agencies, and many other irrelavent issues that don't even come to mind? The question is: should I as a telephone subscriber have the right to know what other telephone subscriber is calling me before I pick up the phone? You KNOW what I think.

Wouldn't it be nice if ALL fax machines could identify themselves BEFORE anything picked up so the same line could share devices? That way, data calls (FAX, MODEM) would automatically route themselves to devices WITHIN A TELEPHONE NUMBER. This could be done if there were a user definable field after the phone number in ANI. As a human, I'd put my name there. Machines would put some standard ID there so all modems would recognize each other. Soliciters would be required (by their telemarketing license as well as laws I'd like to see on the Federal/state level) to put some message like "solicitor". Now, you can know a little about the call requested as well as the originating line number. It could be used like the "subject" line in articles. This way, you could use this information to help screen your calls. All emergency calls (hospital, police) could be identified by this user field, despite your never seeing the number before. Isn't this that you want - the ability to prioritize your calls? A cutsey feature could be programming each phone in your house to transmit a different I.D. That way, when I use the office phone, my name appears on the callee's phone. Other people in the household have their names appear when they use their phones. That way, a recipient knows not just that the call is from the Jonas household, but also can identify who the call is to or from! No more picking up the phone for others! The closest thing I know to this is extensions within a telephone number. It hasn't been mentioned here lately, so I'll ask. Isn't there an ability to pre-dial numbers that get passed to the subscriber (ex: dial the desired extension after the phone number without waiting for the call to complete)? If so, will this be made available to us with the Caller-ID boxes, or will we need a full ISDN feed? I thought some 800 numbers had this, but that's for commercial users that will pay big bucks for features. Some people here on comp.dcom.telecom have premises equipment. I recall reading how they're used to manage several outgoing lines as well as internal services (call holding, intercom). What about some support for multiple extensions (beyond call hunting)?

I don't think there is such a requirement. Each licensed line can pass this information itself. Indeed this is necessary to guard against forgery. While calling cards would probably take the form of such licenses, this does not imply that all calls would require a calling card. The suggestion made about using pseudo phone numbers for the license allows users to substitute the actual phone number if (and when) they want. This would be done by quick setting of the line and not necessarily on a per call basis. This idea may never get to the detail stage...

This displays the phone number of the calling party on a display... <<< enter wish mode I wish I had...>> Rather than having separate lines for voice and data, I'd like a board to my computer (like the Watson board) where it answers the phone with an outgoing message. If you want voice, just leave a message. If you want data, enter a digit (say, '1') and the voice disconnects and the modem connects. (ah, but how to get uucp chat scripts to do this) Me - I'd enter a security code and use the telephone as a terminal: input: the keypad output: tones and speech synthesis What could I control? Anything that a X10 controller can handle (ex: start dinner as I leave the office, stop dinner if I'm delayed) The modem also gets the phone number ANI. This can be used for authentication, or at least log users. When the phone rings, should I pick it up? I don't know if it's a person or a modem at the other end before I pick it up EXCEPT if I know the number of the caller is a modem (from previous registration). Perhaps if the computer recognises the originating number as that of a modem, the modem would answer immediately rather than requiring an entry to connect the modem. This has good security potential. If I use a PC as a smart console, I can log all phone calls on the console (rather than the publically accessable system). This console also monitors that system and sounds an alarm for unusual activity (such as unusual set-UID programs reported by PS). I'd then have a log of when the phone call started, the originating number, and I'd then start logging the serial line (use a line monitor to capture both sides of the session). I emphasize the use of a separate computer for the console and data logging so that the hacker cannot 'cover his tracks' and it's harder to defeat the alarms. Is there a number I can call that tells me what number I dialed? I need this to check my auto dialer. Perhaps auto dialer manufacturers offer such a diagnostic service (like Panasonic, or any phone manufacturer?) My neighbor had a lot of grief when her parent's autodialing phone misdialed her phone number. All I could say was to reprogram the phone. I wish I could have her parents check it for themselves and verify that the number was misprogrammed, or test if the dialer was misdialing. [Moderator's Note: If the distant end answers, *ask them* what number you reached. If the other end is not in service, an intercept message will tell you what number you 'reached' (actually, dialed) in the course of telling you it is not in service. That resolves two possible cases.

Evening rates will drop an average of 2%. AT&T spokesman Herb Linnen said the reductions were necessary under changes earlier this year in the FCC's regulation of long-distance charges. The FCC now imposes caps on AT&T's LD rates based in the company's LD expenses, as opposed to a pre-set rate of return. AT&T said the lowered rates reflect reduced expenses, mainly from reduced access fees that AT&T will pay in 1990 to local telephone companies. Linnen said the reductions would affect both operator-assisted and direct-dialed calls. John Hauser, a spokesman for AT&T's principal competitor, MCI Communications Corp., said that MCI would also pass on savings in local telephone company access charges. "We will remain competitive with them," he said. Hauser's counterpart at US Sprint, Robin Pence, said, "We are reviewing the filing and we intend to remain competitive." AT&T claims about 70% of the LD market. MCI is No. 2 with more than 10%. US Sprint claims 7 to 8%. In a notice filed with the FCC, AT&T estimated that the reductions would save customers $300 million a year on interstate and international LD services used primarily by residential and small business customers. A 10-minute AT&T call during daytime hours on a weekday to anywhere in the US will cost $2.50 or less, an average decrease of 1.3%. Linen said a 10-minute daytime call from Washinton to New York, which now costs $2.30, would decline to $2.20, a drop of 4.3%. An evening call from Washinton to San Francisco, Los Angeles, or Dallas, which now costs #1.67 for 10 minutes, would drop 5.3% to $1.58. The reductions would be less for many other calls. International calls from the 48 contiguous states to 25 of the most frequently called countries wil be slashed by $104 million. The reductions will vary from country to country. ***End of Article*** [Some abbreviations used.] Regards, and happy holidays!

Imagine an accountant in Toronto working with a client in Northern Ontario. The client, a small businessman, has prepared a spreadsheet that represents the financial forecast for his business for the coming year, and wants to review it with the accountant prior to submitting it to the bank. In the past, he would have to travel to Toronto to do this effectively. Now, thanks to a revolutionary mix of computer and communications technologies known as a system for Computer Supported Cooperative Work (CSCW), this is no longer necessary. A single command to his computer causes it to dial and establish a connection with his accountant's computer. Simultaneously, the two are placed in telephone contact using their hands-free speakerphones, and in live video contact through images of each other which appear in windows in their workstations. Furthermore, their screens are linked so that any change to the spreadsheet made by either party is visible in the other's version with no perceptible delay. Available today? No. Science fiction? Definitely not. All the individual elements needed to paint this picture are technically feasible today. Given the anticipated developments in technology and systems integration, reductions in the cost of high bandwidth telecommunications, and results of human factors investigations designed to explore how such visions can be translated into useful, useable systems, this scenario can be a reality in under 5 years. Furthermore, the same system can help doctors in remote locations consult with specialists in distant medical centres, managers in branch offices communicate and coordinate with their counterparts and supervisors in the head office, and programmers at distributed locations work together to write or maintain large software systems. Coverage The lecture series will survey and introduce the state-of-the-art and the potential of this exciting new field. It will attempt to answer such questions as: What are the roles of computer, audio, and video technology is supporting distributed coordinated work? How does software for CSCW, sometimes known as groupware, need to differ from that designed for individual users? What needs to be done in order for such technology to become viable? What is the impact of social and organizational factors? What are the major stumbling blocks hindering the successful development and deployment of effective CSCW systems? Who Should Attend? This technology is of particular relevance to Canadians. MIS managers and others concerned with monitoring, adopting, and managing new technology will find CSCW particularly relevant to communication among individuals and coordination of resources in a country with a widely dispersed population base. Computer and communications researchers in Canada, leveraging upon the country's strengths in communications technology, software, media, and interface design, will find CSCW a particularly fruitful area for the development and marketing of innovative new products. The Lecture Series Tuesday, January 9, 1990 4:00 p.m. - An Introduction to CSCW. Ronald Baecker, Professor of Computer Science, Electrical Engineering, and Management at the University of Toronto, will survey and introduce key concepts and issues in computer supported cooperative work, including computer support for face-to-face meetings, meetings at a distance, and asynchronous communications.

PT] The moderator's views about the divestiture are well known, but the problems enumerated in Will's message can hardly be blamed on divestiture. o "... a dark stormy night, a desperate woman, a telephone from Kafka". Using a pay phone at a service station along the highway, she dialed 0 then the number and the phone went dead. She tried again and again. She finally reached an operator and found out that (a) the phone was owned by a private company (not AT&T), (b) collect calls could not be made, and (c) she could not be connected with an AT&T operator. Customer Owned Coin Operated Telephones became possible as a result of the FCC's Carterfone decision (1968) authorizing customers to attach any sort of device to their phone line, coupled with the decision eliminating AT&T's ban on resale I expect the problem was solved through the use of a call trace capability by the local phone company just as it would have been had AT&T been integrated (1980)--both preceding divestiture.. Thus, even without the breakup, we would have been likely to see this scenario. Indeed, it is a common one in France where COCOT's have been authorized for decades and the telephone company is still a monopoly. o Another woman received hourly calls with the recorded message "The maximum dollar amount is exceeded by the number 4-4-4-4-4-4." The problem was traced to a pay phone at a local gas station with a full coin box. The phone was programmed to call someone when the coin box was full. Unfortunately, it was programmed with the wrong number. Again, this problem has nothing to do with divestiture, but could happen with any sort of autodial customer equipment -- even equipment which was forced to operate through the old Bell Protective Access Arrangement which made modems so expensive for us computer users. Even if we went back to the pre-Carterfone days when all autodialers had to be leased from AT&T, it wouldn't prevent a customer from programming a wrong number. I expect the problem was solved thorugh the use of a call trace capability by the local phone company just as it would have been had AT&T been integrated. o For six months a woman had long distance calls to Mexico City on her bill. The phone company finally discovered that the woman's line was cross wired with a neighbor's line. The twist in the story was that the neighbor had recently moved into the house and did not realize it had TWO lines (the phone company had failed to disconnect the second line when the previous owner moved out). The neighbor's bill looked normal since most of his calls were on his primary line. Only when he used a secondary phone were the calls billed elsewhere. There's nothing in this story to suggest that divestiture had anything to do with the problem -- unless you want to argue that the old AT&T never got customer's wires crossed! o One family had phones that rang three times then stopped. Friends said they called and let the phone ring 20 times and no one answered. "After extensive investigation [GTE] found an electronic glitch at a nearby central office." This story doesn't even involve AT&T, and can thus hardly be blamed on Judge Greene. Indeed, one postive consequence of divestiture is that the equipment market has become more competitive, leading GTE to throw in the towel and merge its switch operations with AT&T. This will likely prove quite beneficial in the long run to GTE customers. In short, the moderator should spare us his non sequiters about Judge Greene.

And France has really great and effecient phone service, don't they? What a great example for Americans! What a goal to strive for! Phone service as good as that in France. COCOTS may have been authorized as of 1968, but they did not begin appearing on the scene until the early 1980's -- once they knew that AT&T was unlikely to find a legal environment friendly enough to stop them. (Example given: woman receives calls from a misprogrammed pay phone telling her the box needs to be cleaned out. This goes on until the call is 'finally traced' to the COCOT proprietor.) >Even if we went back to the pre-Carterfone days when all autodialers >had to be leased from AT&T, it wouldn't prevent a customer from >programming a wrong number. I expect the problem was solved thorugh >the use of a call trace capability by the local phone company just as >it would have been had AT&T been integrated. Indeed, it could happen anytime, but the difference is, now-a-days it is up to the consumer to find out what is wrong, *and convince others*. By this, I mean the lady can call 'repair service' or the operator to report the problem. As far as telco is concerned, there is no problem. *They* don't control the equipment in question, and *their* equipment is working fine...she got the calls, didn't she? And I venture to say when the lady called the COCOT to complain about getting constant calls from one of their phones, she was told to check with the telco. One of the notorious problems since divestiture, now that we get our local service one place, our long distance service somewhere else, and our equipment from a third place, is that all three love to point their fingers at the other two as the troublemaker. In our office, for example, getting the WATS lines repaired is like a three ring circus. The long distance guy says the local telco dedicated circuits to his switch are not working. Telco says it must be our PBX which is not handling the calls correctly. Our PBX guy says call the long distance company. Finally with some effort, I get all three together on our premises at one time, and let them stand there and point their fingers at each other, but none of them leave until my phones are working again. (Example given: people get billed for long distance calls not their own. Problem is found to be crossed wires in the junction box coming into the subscriber's premises. How did the wires get crossed?) Mr. Sirbu notes, >There's nothing in this story to suggest that divestiture had anything >to do with the problem -- unless you want to argue that the old AT&T >never got customer's wires crossed! Yes, AT&T, or more precisely, the local telco did get wires crossed. But that condition is far more common now that the local telco by law cannot work on wires past the point they enter the subscriber's premises. If the telco is going to charge $$$ to come out and install your phone these days, and you have the option of having 'someone else' do the work, then you get 'someone else' (the building janitor, maybe?) who claims to know what he is doing. It is frightening to me to realize that in a large apartment complex or office building, with a big IT in the basement, that anybody and everybody these days who wants a phone installed is free to get in the cabinet and tamper with the wires. So the victim of the cross-wiring with the wrong calls on his bill calls the long distance supplier, and gets a third degree run-around. He calls the local telco, and is told they have nothing to do with the wires in his building or long distance. The building manager says call the telco. The telco says call the long distance company. I am victimized when you moved into the apartment across the hall and your friend said he could save you big money by doing the installation himself! An unusual and rare occurence? Not in the big city in many older neighborhoods. Tenants in an apartment building have gotten into physical fights with each other accusing the other of stealing their service or cutting the wires off entirely, etc. In big, older urban areas like Chicago, multiples come up all over the place in the cable run. You go to the basement of my building -- private property where the telco can no longer under law work without charging a hefty fee -- and you'll find pairs for everyone on this block. So your efforts to wire your phones victimize several other folks in the vicinity. Even novice installers from the local telco in the old days did not bungle things so badly! (Example given: Problem in the switch causes subscriber to lose calls.) >This story doesn't even involve AT&T, and can thus hardly be blamed on >Judge Greene. Indeed, one postive consequence of divestiture is that >the equipment market has become more competitive, leading GTE to throw >in the towel and merge its switch operations with AT&T. This will >likely prove quite beneficial in the long run to GTE customers. In the old days when I reported a condition like this, someone looked into it and repaired it. Now, when I call Repair Service, I am given a third degree questioning: Have I tested every phone in my house? Have I unplugged all but one, tested it, and used a process of elimination? Can I prove it is a central office problem and not a problem on my end? Am I aware that if telco comes out to my premises a week from Tuesday and finds the problem on my end I will receive a hefty bill for having bothered them? I know how telephones work, and I can't get through their questioning at times; what about the average consumer? >In short, the moderator should spare us his non sequiters about Judge Greene. Mr. Sirbu is, of course, technically correct. No matter where you look, you'll not find any piece of paper signed by Harold Greene saying COCOT proprietors are free to screw the (relatively ignorant of telephony practices) consumer. No where did he sign off on anything saying service was to get worse, or that the conditions given in the examples were to be permitted to exist. But....what could he *possibly* have expected to happen otherwise? COCOTS began proliferating once Greene set the pace. Long distance rip-offs began in an agressive way once Greene set the pace. By the court's portrayal throughout the entire divestiture process of AT&T as an evil giant which had to be squashed, everyone understood what Greene was saying, which was that AT&T, in his estimation, was a bad organization which had to be stopped. He could have easily permitted competition without smashing AT&T in the process; but instead, he took a century of fine-tuning and carefully planned practices which had given the USA the finest *totally integrated* phone network in the world, bar none, and indicated his willingness to see it picked apart. Unlike other utilities such as electricity and gas, where your use of the utility is of little concern to me, as to what you attach to the pipes or wires, telephones are different: it takes two to tango, so to speak, and my service becomes worth less or more in large part based on the configuration of your service and equipment. That's what made the Bell System so successful over the decades: One way of doing things; one standard; everyone shape up or ship out. Greene could have authorized competition by telling MCI/Sprint and others they were free to compete; and that they could spend the next century developing a system or network equally as efficient and good as Bell if they desired. You say its not fair to MCI/Sprint to have to spend that long to accomplish it? Who gave AT&T and the Bell System any breaks over the past hundred years? Where did Greene find the moral or ethical authority to force AT&T to sell off its property? Mr. Sirbu is indeed correct: Divestiture was a very narrow thing; it said only a few words, relative to all the water which has passed under the bridge in the past five years; but ideas have consequences, and I can't imagine Harold Greene didn't know that from the moment he first entertained the concept of divestiture in his courtroom.

The price decrease would take effect Jan. 1, 1990, and apply to AT&T's basic long-distance service, most international calls and Reach Out(R) America, the company's optional long-distance plan for consumers. The decrease, AT&T's 10th since 1984, would bring total reductions in long-distance prices to 40 percent in the six years since the breakup of the Bell System. When the Jan. 1 decrease takes effect, a 10-minute AT&T call, at any time of day to anywhere in the continental United States, will cost $2.50 or less. Placed during the night/weekend calling period, such a call will cost $1.32 or less. The price cuts, filed late Monday with the Federal Communications Commission, reflect reduced expenses, primarily from lower fees AT&T will pay in 1990 to local telephone companies for access to customers' lines. Under FCC guidelines, those cost savings lower the "price cap" on AT&T long-distance services. AT&T's proposal includes: o A 1.3 percent drop in prices for basic long-distance service during the weekday calling period (8 a.m. to 5 p.m. Monday through Friday) and a 2 percent drop during the evening calling period (5 p.m. to 11 p.m. Sunday through Friday). o Greater discounts for subscribers to the Reach Out America 24-Hour plan. Customers of the plan will receive a 10 percent discount, up from 5 percent, on weekday calls, and a 25 percent discount, up from 20 percent, on evening calls. Reach Out America's evening calling period is from 5 p.m. to 10 p.m. Sunday through Friday. In addition, AT&T on Friday, Dec. 15, proposed to extend its waiver of the sign-up fee for new Reach Out America subscribers through Jan. 31, 1990. o A $104 million price reduction on international calls from the U.S. mainland to 25 of the most frequently called countries and overseas areas including Canada, Mexico, Japan, the United Kingdom, France, Italy, Israel, Brazil, Australia, the Philippines, Taiwan and Korea. The percentage reduction varies by country and time of day. o Lower prices for AT&T World Connect(sm) Service to 39 countries or territories. AT&T World Connect Service gives frequent international callers a discount on direct-dialed calls from the U.S. mainland. o Reductions in basic long-distance prices from Puerto Rico and the U.S. Virgin Islands to 95 countries and territories. # # # Don H Kemp "Always listen to experts.

Antenna "gain" is most common in the RF world. It involves the amount of energy radiated in a given direction from the antenna. In a given azimuth, a 5/8 wave antenna (as used in cellular mobile phones) radiates more energy than a 1/2 wave reference dipole for a given RF input. An easy way to visualize this is to refer to the case of an FM broadcast antenna (oh, no, Martha, here it comes!). If you take a single "bay" or element and you could see the energy being radiated from it, it would appear as somewhat spherical, coming off in every direction. Unfortuately, the receivers are all out at some horizontal distance from the antenna. There are hardly any listeners in the sky or under the ground, so all that energy is being wasted. If you place a second bay on the tower exactly one wavelength's distance above or below the first and divide the energy between the two, the formerly spherical pattern will now "flatten out", with more energy being radiated out horizontally and less going up and down. The antenna is now said to have "gain" over the standard dipole. No energy was created, just redirected in a more useful manner. The ERP (Effective Radiated Power) from a standard dipole equals the Input Power to the antenna which is close to the transmitter output power. The ERP from a "gain" antenna is equal to the Input Power times the power gain of the antenna. In the case of our FM example above, adding that second element would give the antenna a gain of 2. The gain of a 5/8 wave antenna is approximately 1.3 referenced to the standard 1/2 wave (I think--don't work with those much). I know more about FM antennas than cellular, but the principle is the same. John Higdon | P. O.

Well, I just comfirmed moments ago that my office phone in Santa Clara would indeed forward at least three calls, assuming that each of the preceeding calls was supervised. It is served by a 1AESS co-located with the Pac*Bell tandem. However, when I tried the same trick on my home phone, it didn't work. My home phone is handled by an unknown number of trained hamsters (1ESS). With its 1951 generic, I'm not surprised. This little experiment would lead one to believe that multiple forwarding is something that can work on a switch-by-switch basis. I would suggest that you might try other Boston area switches, but that doesn't solve your problem with your particular switch. > This is for my > residential service -- I've heard that you can indeed ask that > multiple calls be allowed through, but the phone company people are > baffled when I try to explain the situation. As much as I kinda doubt it, maybe there is a distinction between forwarding on business vs forwarding on residential. It's ridiculous, but who knows? John Higdon | P. O.

Unless the carriers are providing calling number identification to customers for free (fat chance!) they must file a tariff for the service with the FCC. AT&T did indeed file a tariff with the FCC for its Info-Call service and charges 2-3 cents per calling number delivered. We can thank the FCC for completely igonoring the privacy aspects of the tariff and approving it without much fanfare. The FCC could have chosen to take the same policy stance as the California PUC and mandate the ability to block calling line forwarding to *IEC customers* (though not of course to the IEC itself which needs the number for billing purposes). They chose not to.

Well, with all of my railings about Pac*Bell, I guess it's time for the equal fairness doctrine. I have experienced none of the above. Yes, the frontline person always asks if I am sure my equipment is OK, but all I have to say to end that thread is tell him/her that I have checked it at the "network demark". That ends that. What follows makes the "old days" look like the dark ages. Within minutes, someone is testing the line (the frontline person performs a continuity test while you're talking to them; you can hear the click and they ask you if you are talking on that line). Within about an hour, a technician calls you back if they need additional information. This person will "talk telephone" with you and does not treat you like an idiot. If you speak over his/her head, you are put on the line with yet another, higher level, person. If the trouble cannot be located in the CO, they will dispatch. And it isn't a week from Tuesday; they are very apologetic if they can't send someone out the very same day (you never wait more than 24 hours, including weekends). Now I'll tell you how they handle businesses. That's when they really haul ass. You phone repair service at 1:00 am and the call-back person (who calls before 2:00 am) will ask (again if the problem requires it) if you can wait until business hours for a dispatch, or you need one *now*. The majority of all service calls are handled same day, usually with an hour or two. What else could you want? I don't know how it is in other RBOCs, but Pacific Bell's Repair Service is first class all the way, and a resounding improvement from the days of Pacific Telephone.

It is true that tariff would have to be filed with the FCC, but I had discounted that when I made my comment. With the exception of broadcasting, the FCC has historically avoided "social engineering" aspects of the communications field. Originally, the purpose of the FCC was to prevent chaos on the airwaves. From a logical point of view, the FCC was correct to ignore the privacy aspects of 800 caller number delivery. It's only function should have been to ensure that the technical aspects of the feature were sound, did not violate any other *technical* provisions of the rules and regs, and to advise on the suitability of the proposed charge. Yes, indeed, we can thank the FCC for doing its job, and not assuming the role of thought policeman for us all. BTW, answering an 800 number without calling number delivery is roughly equivalent to answering a POTS line and having the operator say, "I have a collect call, you've just accepted the charges, and it's none of your business who it is." But back to the FCC for a moment. To get an idea why I am against the FCC meddling in areas other than technical one only has to look at the way the commission handles the broadcaster. As you are no doubt aware, commissioners are appointed by the party in the White House. Over the past twenty-some years that I have been in the business, the FCC's policies directly reflect the political leanings of the moment. For instance, under Johnson, the FCC set up this incredibly exhaustive list of requirements for public service that radio and television station had to adhere to in order to keep their license. Every three years, each and every station had to prove that they had met their public service commitment. You remember public service, the stuff that played every Sunday morning and late at night that no one listened to. Many of these requirements lasted through the Nixon-Ford administration, and stayed with Carter. Broadcasters jumped for joy as the Reagan administration promised to ease up on all these programming requirements. That plus a relaxing of many technical rules was heralded as a major step forward. They thought they had arrived. The Republicans had a surprise in store. Reacting to fundamentalists and other righteous folk, the FCC has now set itself up as the Prudence Peabody of the airwaves. For instance, a station in Las Vegas was recently fined for playing a rock record (I forget what) that somebody thought was obscene and complained about it. Never mind that the same record routinely plays everywhere else in the country, or that the place was, after all, Sin City. The FCC considers a station guilty of obscenity until proven innocent--and most stations would rather pay the fine than the high costs of litigation. So this is what happens when the FCC tries to diddle with things that are not related to the nuts and bolts of communication. I would rather not have the FCC consider the social ramifications of the entities that they oversee and stick to their design function: the establishment and enforcement of technical standards in our communications services. > The FCC could have chosen to take the same policy stance as the > California PUC and mandate the ability to block calling line > forwarding to *IEC customers* (though not of course to the IEC itself > which needs the number for billing purposes).

Tallinn was dialable in 1980 before Brezhnev shut off all incoming traffic from the west, but not now. I believe that AT&T feels that the grade of service (either due to number of lines or line quality) to Tallinn is not adequate for direct dial service and would prefer to have operators assisting customers who want to call.

Doughney" Subject: USOCA Press Release on Privacy Issues [The following is from a press release issued 12/19 from "Bonnie Guiton, Special Adviser to the President for Consumer Affairs, and Director, United States Office of Consumer Affairs". Large parts of it address issues seen frequently in TELECOM Digest.] SAFEGUARDING YOUR PRIVACY: TEN WAYS TO KEEP THIS NEW YEAR'S RESOLUTION by Bonnie Guiton 1990 begins a new decade that will be marked by quantum leaps in technological innovation. These innovations will certainly benefit consumers; but they also create concerns about the collection, storage and dissemination of personal information and buying habits. You may have seen or read stories about violations of an individual's privacy -- pertaining to financial and credit records or insurance and medical records. What concerns one consumer may not necessarily concern another. But if you are concerned, you can help protect your privacy in a number of ways, and the new year presents a good opportunity to adopt simple, safeguarding habits. Here are the top ten: [Omitted sections 1-4 concerning credit records, medical records, and incentive programs.] TELECOMMUNICATIONS 5) LEARN ABOUT WAYS TO PROTECT YOUR PRIVACY ON THE TELEPHONE Caller ID: You may have been hearing a lot recently about Caller ID. It is New Jersey's version of "automatic number identification" service soon to be offered by local phone companies in several other states. Subscribing to an ANI service allows you to protect yourself from unwanted callers. The caller's number will show up on a read-out device attached to your phone. If you don't recognize a number, you have the choice of answering it or not. If you don't want your own number revealed to those you call, just dial through an operator, or from a public phone. Answering Machines: A "low-tech" version of "Caller ID" is the more familiar answering machine. If phone calls at home are becoming intrusive, an answering machine can be used to screen calls, and may be a worthwhile investment for you. Cellular and Cordless Phones: Cellular and cordless phone conversations are easily monitored -- both intentionally and unintentionally. Be careful that you don't conduct confi- dential conversations on a cellular/cordless phone. 6) ASK TO OPT OUT OF MARKETING PROGRAMS RUN BY COMPANIES THAT PROVIDE 800 AND 900 NUMBERS While the private home use of ANI technology is very new and experimental, the commercial uses of ANI technology are not. Many 800 and 900 number switchboards have the capability of capturing your number and matching it to your name and address to create customer lists. Many companies have legitimate reasons for creating such lists -- to keep track of customer complaints or consumer product inquiries, for example. But some consumers object when the list is sold to marketers without the callers' knowledge or consent. And that is why it is important for you to register your desire to either participate in or opt out of those marketing programs using lists provided by companies you contact. DIRECT MARKETING Many people appreciate direct mail and telephone offers. But businesses have difficulty determining who they're pleasing, and who they're offending, when they conduct sales calls and direct mail promotional campaigns. So they appreciate hearing from potential customers who aren't pleased as much as from those who are. 7) SUBSCRIBE TO THE TELEPHONE PREFERENCE SERVICE (TPS) The Telephone Preference Service is sponsored by the Direct Marketing Association. By notifying TPS that you do not wish to receive telemarketing calls, your name will be struck from the lists of DMA members who participate in the service. For DMA members, the service is a business tool; for all telemarketers combined, 3% of consumers contacted appreciate the calls, while 80% do not. The Telephone Preference Service helps DMA members reach only those consumers who want their offers. Write: DMA Telephone Preference Service, 6 East 43rd Street, New York, NY 10017 8) DON'T GIVE ANY MORE INFORMATION THAN IS NECESSARY The most simple thing you can do to protect your privacy is to get in the habit of saying "no" to telemarketers you're not familiar with, to those who want more information than you feel is necessary to complete the business at hand, and to those who refuse to send you follow-up explanatory materials. Never give your credit card number over the phone unless you initiated the call, or are completing a transaction with a known vendor. Never give your credit card (or Social Secur- ity) number over the phone for identification purposes only. [Omitted sections 9-10 concerning mailing lists.] By following one or all ten steps and incorporating them as daily consumer habits, you can protect yourself from intrusions of personal privacy in 1990 and beyond, and still enjoy the many benefits of our modern, high-tech marketplace. - end - Note to editors and reporters: Bonnie Guiton is taking the lead for the White House on the issues surrounding consumer privacy.

Now, they are at it again. A new regulation that the FCC is quietly working on will directly affect you as the user of a computer and modem. The FCC proposes that users of modems should pay extra charges for use of the public telephone network which carry their data. In addition, computer network services such as CompuServ, Tymnet, & Telenet would also be charged as much as $6.00 per hour per user for use of the public telephone network. These charges would very likely be passed on to the subscribers. The money is to be collected and given to the telephone company in an effort to raise funds lost to deregulation. Jim Eason of KGO newstalk radio (San Francisco, Ca) commented on the proposal during his afternoon radio program during which, he said he learned of the new regulation in an article in the New York Times. Jim took the time to gather the addresses which are given below. Here's what you should do (NOW!): 1- Pass this information on. Download MOBILIZE.ZIP which contains the text you are reading now. Find other BBS's that are not carrying this information. Upload the ASCII text into a public message on the BBS, and also upload the file itself so others can easily get a copy to pass along. 2- Print out three copies of the letter which follows (or write your own) and send a signed copy to each of the following: Chairman of the FCC 1919 M Street N.W. Washington, D.C. 20554 Chairman, Senate Communication Subcommittee SH-227 Hart Building Washington, D.C. 20510 Chairman, House Telecommunication Subcommittee B-331 Rayburn Building Washington, D.C. 20515 Here's the suggested text of the letter to send: Dear Sir, Please allow me to express my displeasure with the FCC proposal which would authorize a surcharge for the use of modems on the telephone network. This regulation is nothing less than an attempt to restrict the free exchange of information among the growing number of computer users. Calls placed using modems require no special telephone company equipment, and users of modems pay the phone company for use of the network in the form of a monthly bill. In short, a modem call is the same as a voice call and therefore should not be subject to any additional regulation. Sincerely, [your name, address and signature] It is important that you act now. The bureaucrats already have it in their heads that modem users should subsidize the phone company and are now listening to public comment. Please stand up and make it clear that we will not stand for any government restriction on the free exchange of information.

Here is a brief outline: Since August, 1988, a temporary credit has appeared on everyone's bill each month entitled 'Credit Due to Rate Reduction'. That credit will not appear starting with January cycle billings, because the rate reduction was made permanent. Illinois Bell had been required to issue the credit each month while the matter was under advisement by the Illinois Commerce Commission. The cost of local calls has been reduced. We will *no longer have message units*. A per-minute billing will replace unit billing and apply to each call. As is the case now, the rates will be about five cents per call, no matter how long we talk on calls within our local (eight miles) calling area. The cost of calls outside the local area will continue to depend on the number of minutes used, the time of day of the call, and the distance of the call. EXAMPLE: A five minute call during the peak phone period. Type of Call Current New Local Area 5.2 cents 5.2 cents 8-15 Miles 20.8 cents 17.1 cents 16-40 Miles 27.5 cents 24.2 cents 41+ Miles 45.7 cents 42.1 cents Rates for calls between Illinois Bell phones and locations served by other local telephone companies (i.e. Centel) will be reduced by 25% beginning in July, 1990, except that calls from IBT/Chicago-Newcastle to points served by Centel will continue to be billed as local area calls, with no reduction, remaining 5.2 cents each. Also on January 1, 1990, the monthly line access charge will increase by $1.03 per month for most residence customers. Illinois Bell says this will bring the charge closer to the actual cost of providing the line from the CO to the residence. Illinois Bell says even with this increase however, most customers will see a reduction in over-all costs because of new time- of-day discounts being introduced, as follows: Calls originating between 9-11 AM and 2-8 PM Monday through Friday will be billed at the standard rates shown above. Calls made Monday through Friday between 8-9 AM, 11 AM-2 PM, and 8-9 PM will be given a ten percent discount; i.e. a local 5.2 cent call will cost about 4.5 cents. A standard rate call costing 30 cents will cost 27 cents during these three time periods. Calls made between 9 PM daily and 8 AM next day will receive a forty percent discount; i.e. a local 5.2 cent call will cost about 2.8 cents. Calls made between 9 PM Friday and 8 AM Monday (all day Saturday and Sunday) will receive this forty percent discount. Calls which overlap time periods will be billed on a pro-rated basis, with a portion of the call billed at each applicable rate. There will no longer be discounts given for volume purchases of units, since units per se are being discontinued. Finally, Call Waiting, as a stand alone feature of custom calling will be reduced from $3.00 to $2.50 per month. Most custom calling features will have some reduction made. Business rates for custom calling features and touchtone service will be reduced to match rates currently paid by residential users of these features. In a few months, I will let you know how it actually works out on my bill. In Wednesday's Digest, I have extensive details on the CLASS options being made available to Illinois Bell subscribers during the second and third quarters, 1990.

Goldstein) ---------------------------------------------------------------------- Date: Tue, 26 Dec 89 1:37:18 CST From: TELECOM Moderator Subject: New Illinois Bell CLASS Options The CLASS options being phased in by Illinois Bell during 1990 will be those listed below. Some CO's will be equipped in the second quarter, 1990, while others will be equipped in the summer or fall. My office (Chicago- Rogers Park) is set for fourth quarter, 1990. Please note, the infamous 'Caller-ID' will *NOT* be offered by Illinois Bell at this time. The features we will have are these: Automatic Callback - Dial *69 (rotary, dial 1169) The number of the last call *received* will be dialed automatically, and attempts will continue for thirty minutes if no answer, or indefinitly until the busy number is free. We will get a special ring when the other line is free. On answering, the other line (if it was busy) will begin to ring. It won't work with long distance calls or calls to offices not yet served with this feature. An intercept recording will advise that the call cannot be returned. To cancel a pending request, dial *89 (rotary, dial 1189). This can only be used to return *incoming* calls. There is no time limit on when you can return the call, as long as you do so before you make or receive other calls. Call Screening - Intercept calls from up to ten designated numbers. Callers will then receive the following announcement: "Your call cannot be completed. The number you are calling has activated Call Screening, indicating that they do not wish to recieve your phone call at this time." To activate Call Screening, dial *60# (rotary, dial 116012). Listen to the recorded instructions explain how to designate up to ten numbers for Call Screening, or how to make changes in your Call Screening list. To add a number at that point, dial # (rotary, dial 12), wait for three confirmation tones, then dial the number to be added. Now touch tone customers dial # again; rotary, wait for time out. To remove a number from the list, dial * (rotary, dial 11), wait for three confirmation tones, then dial the number to be deleted. Now touch tone customers dial * again; rotary, wait for time out. You can also delete an individual entry by dialing 07 after it is read aloud to you by the computer. To reject the number of the last call you received, when the number is unknown, such as an obscene or nuisance caller, dial # (rotary, dial 12), wait for three confirmation tones, then dial 01 in place of the number when prompted. Now touch tone customers dial # again; rotary, wait for time out. When the list of screened calls is read aloud to you, these numbers unknown to you will be termed 'private entry' by the computer. To clear the entire list, dial *80* (rotary, dial 118011). Listen to the recorded announcement which follows, which will ask you to confirm that you wish the entire list deleted. If you dialed this in error and wish to save your list, simply hang up. Distinctive Ringing - You may designate up to ten numbers for 'special' ringing. When you receive a call from one of these numbers, your phone will ring in a distinctive pattern. Designate numbers of family members, employers, etc for special treatment in this way. Dial *61# (rotary, dial 1161612). A recorded message will guide you. To add or delete a number, follow the instructions given for Call Screening. To clear the entire list, dial *81* (rotary, dial 118111). A confirmation tone will ask you to verify what you are doing. Repeat Dialing - To call back a busy number, dial *66 (rotary, dial 1166). You will hear ringing, followed by a recording telling you the number is still busy (if it is). If the called number is free in the next thirty minutes, you will be called back with a special ring. Only after you answer will the ringing commence on the other end. To call back the last number *you dialed* -- NOT THE LAST CALL YOU RECIEVED -- dial *66 (rotary, dial 1166). The number of the last call you made will be dialed automatically. If the number you are attempting to call back or repeat dial is a long distance number or outside the area served by Repeat Dialing, you will hear a recording advising you that the call cannot be made. To cancel Repeat Dialing requests, dial *86 (rotary, dial 1186). You can only use this feature on calls you dialed. To return calls you *received* you must use Automatic Callback. Call Identification Service - ($4.95 1st addl. line; $3.95 2nd addl. line) You receive up to three phone numbers, each with a separate listing if you wish. These will all ring on the same single line, but each will have a distinctive ring. Main number will have standard ring. First addtional line will have two long rings then a pause. Second additional line will have one short, one long and one short ring. Call waiting: first addtional line will have two tones. Second additional line will have three tones. Call forwarding: Customer can have all numbers forwarded, or only the main number forwarded. This has to be done in the central office. On forwarded calls, the different lines will not have unique rings. If the additional lines are not forwarded, they will continue to ring in their unique way at your premises and may be used in the normal way. You must wait for a complete ringing cycle in order to know who is calling and use the appropriate answer phrase. The calling party hears only normal ringing, not the special ringing. Answering machines may 'count' the unique rings in an odd way, and answer inappropriately. This service is used to designate one number for family members, one for after hours emergencies from your employer, one for children, etc. Intercom Calling - (Announced price: $6.50 per month) Dial a two digit code and hang up. Phones throughout your premises ring in a unique way. Based on ring sounds, others know who is to answer. On an incoming call, flash to put caller on hold, dial two digit code. Hang up. When the called party answers the call will be connected. To make an intercom call, dial the two digit code. Hang up and wait until ringing stops, then lift the receiver and talk to the other party. An incoming CO call during this time will generate a call-waiting tone. Hang up to take the outside call. You can also hold calls, and move to a different extension to resume the conversation. Patrick Townson ------------------------------ From: "David E. A. Wilson" Subject: Some Australian/USA Comparisons Date: 24 Dec 89 11:19:47 GMT Organization: Uni of Wollongong, NSW, Australia Just got my telephone bill and it contains a little leaflet. I thought I would share some of its contents with you and ask a few questions. "By the mid-1990s we intend that every domestic customer in Australia will have a push button phone." Has a claim like this been made anywhere else in the world (or has this been achieved)? "What Telecom handles in one year - 10,000 million phone calls - including 85 million overseas calls - 7.4 million phones in operation - 124 million 'dial-it' service calls - 683,000 new telephone services - 1871 new connections daily Handled by 84,000 staff What Telecom spends in one year - A$2,810 million to employees on wages, superannuation & compensation - A$1,240 million to lenders, as interest on loans - A$2,240 million reinvested in the business..." How does this compare with other phone companies around the world? Re all the fuss about area code splitting in the USA: With the Australian/ British (where did it start?) format of area codes starting with 0 we will never have your problem of not being able to use some area codes because they look like exchange prefixes. How long is it expected to be before 10 digit phone numbers have to be dialed as 1+10 digit numbers? Re 800 numbers and dialing the real number: In Australia we have the same choice when we get a 008 number - either it is a new phone + line or it is overlaid on an existing service and both the old & 008 numbers can be used. Re cellular phones eating up numbers in LA: In Australia our cellular phones have their own prefix (018) and thus do not contribute to code splitting. Is this not possible in the USA because of the splitting up of the Bell network? Merry Christmas & a Happy New Year from Wollongong, Australia.

Brett Glass" Organization: None whatsoever.... ;-) I'm working on (re)wiring an old house for telephones, and need to be able to identify which line I'm on without tracing the wires through other tenants' apartments. I understand that Pacific Bell installers (and, in fact, installers in most telephone companies throughout the world) have set up a machine that tells you the number you're calling from when you dial a certain 3-digit code. When I lived on the east coast, the code was common knowledge and was often used by folks installing their own wiring. Does anyone know what the code is nowadays? When I called the business office, the person who answered had no idea that such a thing even existed. If you know how to reach the machine in my area (Palo Alto, CA) or anywhere else (many use the same numbers), please send e-mail. It'll save me a lot of probing! [Moderator's Note: Here we go again! There is *no single, standard code* which applies everywhere. It varies from community to community. If anyone knows the number currently in use in Palo Alto, please write this fellow.

This again. It's becoming the new Chain Letter. It popped up in comp.unix.wizards last month and I think I had it squashed there, but alas, this moderated group has allowed it to surface. Here's the poop. When the new FCC chair Alf Sykes was being confirmed, he was grilled on this topic by Congressman Markey, who chairs the House subcommittee that oversees the FCC. Sykes was made to swear on a stack of bibles, so to speak, that this "enhanced service provider" (not modem, btw, though the two often overlap) surcharge was dead. Markey made clear that a congressional LAW preventing it was being put on the back burner only out of courtesy to Sykes. If Sykes hadn't been so docile, the law would have been passed; Congress doesn't like this crap any more than we do! And Markey does have power over Sykes to hit him where it hurts in case he is lying: His subcommittee oversees the FCC's budget and appropriations. In government, that's everything. I do have a copy of the appropriate Congressional Record article (Nov. 6, 1989) quoting Markey on this, and Markey's press release on the subject. So I'm not rumormongering. Someone on Fidonet is.

What's unfortunate about it is how many not-quite-truths make it into the discussions. For example, John Higdon's messages are well argued, but often miss the point. He claims (correctly) that Caller ID could be very useful to him, and to others. Fine, but from that it does not follow that the privacy issues others have raised are of no import. Another interesting claim he makes is that the alleged privacy right here is an artifact of history - had Caller ID always been available, no one would question it. This is a false reading of history. In fact, essentially ALL our notions of privacy are fairly recent, and could be seen as artifacts of history. Doors date back only a few hundred years. Glass windows are even more recent. The degree of "personal monitoring" in the small towns of yesterday would be considered grossly unacceptable by almost anyone raised in today's Western society. (I know to little about other societies to feel secure in saying anything about them. But things do vary - I am told that in Japan, to this day, bank statements are sent out on postcards, and no one is particularly bothered by this.) Expectations of privacy develop through experience in the world; I know of no ab initio arguments for what should and should not be private. Higdon does not expect his phone number to be private. Others disagree. Neither side is "right" or "wrong" here, and I'd say neither side is likely to convince the other - these are gut reactions, learned over many years. The issue is not one of right and wrong, it is one of public policy. Whatever Higdon may want, there will always be cases in which calls he receives will not contain an ID he will find useful - calls from pay phones, for example. He can't base his arguments on an "every call ID'ed" model; anything he does must be useful even if some calls are "anonymous". Technologically, the possibilities are clear - and even supported by the relevant standards: 1. A caller can select to send an ID, or not to send an ID. 2. A caller can set either sending an ID, or not sending an ID, as his default. 3. A callee can select to read the ID sent, or not to. 4. If the callee selects to read the ID sent, he may refuse any call that does not provide an ID. From a strictly logical point of view, allowing (1) provides callers with an additional choice while imposing no constraint on callees that, as I noted, was not there to begin with. Given that (1) is available, there is no logical reason for not allowing (2) - it makes things easier for him and has no effect on anyone else. Given that (1) is available (and especially that (2) is available), there is no logical reason not to give callees the choices in (3) and (4). Now, Higdon will argue that giving callers choices (1) and (2) will decrease the value of his choice (3). Fine - why should the rest of the world's choices be constrained by his convenience? Presumably a "philosophical debate" of sorts will emerge as people "vote with their fingers": If most people agree with Higdon that having their ID sent is no big deal, hardly anyone will exercise choices (1) and (2). On the other hand, if most people DO feel this is a big deal, Higdon may find himself rejecting most calls out of hand. To which all I can say is, too bad - the voice of the majority will have spoken, and it will have said that Higdon was wrong in his estimation of where most people consider their privacy rights with respect to phone numbers to lie. Finally, the real crux of the matter here is money. Who should have to pay for the various choices? The phone companies would obviously argue that EVERYONE pays - those who want to read Caller ID pay, those who want special privacy pay (as they pay now for unlisted numbers). If phone service were a free market, this would, I suppose, be fine. (Well, maybe not. After all, we do have laws against extortion and blackmail, "free enterprise" notwithstanding. At what point we consider a service to become extortion, and beyond the pale, is difficult to determine; "honest men of good will" may differ.) However, phone service is not a fully free market, nor can it be, so questions of fairness come into play. The phone companies have argued that it costs them extra to keep numbers unlisted, so they should be entitled to charge for that peculiar negative service, but the additional costs for providing choices (1) and (2) should be minimal. Further, I'd argue that the entire system is being created for the benefit of subscribers who wish to exercise choices (3) and (4) - if not for them, choices (1) and (2) would be non-issues. Since it is those who exercise choices (3) and (4) who create the need for OTHERS to exercise choices (1) and (2), the fairest approach is to let THEM pay the costs. Frankly, I doubt this will make any significant difference in what Caller ID users are charged (since rates for "custom" telephone services have little or nothing to do with the incremental cost of providing them anyway) - but it will make the system seem much fairer to those who choose not to use the new services. -- Jerry ------------------------------ From: "Steven W.

Up until a few years ago all long distance dialing in BC was done with 112-XXX-YYYY. BC Tel switched us over a year or three back. It is possible for companies in the US or Canada to get 800 numbers that work across the line. I believe since about 1982. AT&T for example has 800 numbers that are available in Canada for ordering documents (although I believe our 800 numbers are different from the US ones). SCO (as in SCO Xenix) has an 800 number that get's you into their sales department (and in this case the 800 number is identical to the US one). I use this as a test of how much a company wants Canadian business. If they have an 800 number and it doesn't work in Canada I form the opinion that they are not interested in my business.

This sounds like the weird things I have been getting at work on our response cards from some outfit in Kansas City calling itself "Bonnhoeterloff". I checked with the Zip+4 folks at the post office, and the address is a mail drop. For fun, I sent a memo to this outfit, and got a response even more bizzare, about how they were in the "information business", and they wanted us to submit data on our products classified according to their strange "system".

As a Compuserve advisor I did some beta testing of the TFD (Toll Free Directory) on Compuserve. Its a simple database look up program. You can however do lookups based on a couple of options. name, state, city and product type. The database will provide toll free numbers and list the state the numbers are valid from. It will also list a direct dial number if toll free is not available from your area. (I'm not sure if this was in the production release). The big problem is it is slow. You can call 800 info and get the number faster. The other problem is you need a CIS account. The computer connect time may be free but you still incure network access time.

I hope the moderator won't censor my "amen" to Marvin Sirbu's comments. I'm also sick and tired of hearing our "moderator" treat Judge Greene like the Spanish Inquisition. I was working in the telecom biz before "divestiture" and while there are certainly problems, I hardly think it's nearly as bad as Patrick likes to claim it is, and most of the problems I see have very little to do with divestiture itself! It's rather like laying blame for the cold weather on divestiture: There's no causality, but heck, wasn't it warm back in the winter of '77? COCOTs are an oddity. They do stem from a set of circumstances that very remotely include divestiture, but mainly they're an FCC creation. Remember "mad monk Mark" Fowler, the Ceaucescu of M St., who ranted his way through his FCC term about "competition" while really doing everything in his power to help monopolies crush it, and mainly screw the consumer. I think I've posted this before, but COCOTs as we know them stem from the following succession of events: 1) Carterfone allowed customers to plug things into phone lines. This was a 1968 decision that broke one of the most noxious monopolies in modern history and made technological progress possible. But Carterfone and the later Registration rules (Part 68) made one excetion: Pay phones. That was because existing pay phone technology would have left too much chance for fraud. COCOTS were invented later, and depend upon microprocessors. So... 2) In the early '80s, the FCC decided to allow registration of phones with coin slots on them. They look like regular phones to the telco line, so the old rules were technologically unnecessary. Of course, you couldn't have made money on them except for... 3) Sharing and resale. In the '70s, the FCC overrode AT&T rules against sharing and reselling lines. Europe, of course, always allowed the monopoly-provided calls to be resold, since the monopoly always got its due. AT&T was even stricter, though, and had allowed no resale. That made Full Time WATS practical, and it was the first casualty. (TELPAK also was a victim of resale.) So if you could resell interstate calls (intrastate being governed separately), you could make money on a COCOT. But how could you handle the big-money coinless toll calls? Enter... 4) Equal access. This part came from divestiture. The idea was to make MCI et al equal to AT&T. So anybody's Long Distance company could get access to Bell bills. At any rate. Thus the AOS scumballs came into being. The FCC has every right to regulate them, of course, as the states can (and do) regulate their intrastate calls. But the FCC seems to like scumballs. All the judge did was require the FCC to treat AT&T, MCI and scum more or less equally, though AT&T's rate setting is still (quite reasonably) subject to increased scrutiny due to its overwhelming market power. I should also point out that it was the Dept. of Justice (again Reagan's ideologues) and AT&T who cooked up the divestiture as a response to an old (1949?) festering anti-trust suit where AT&T appeared to be incredibly guilty. So rather than separate Western Electric (leaving AT&T a PTT-like service provider), as the original suit had asked, AT&T made the deal to keep WECo and become a big force in computers (heh heh). The Judge simply ironed out the most noxious portions of the deal, leaving a few crumbs for the RBOCs. But our revisionist moderator's version of history seems to blame it all on the Judge. Oh well, a nice simple but wrong answer is always easier to spew out than the more complex truth. Fred R.

Using a pay phone at a service station along the highway, she dialed 0 then the number and the phone went dead. She tried again and again. She finally reached an operator and found out that (a) the phone was owned by a private company (not AT&T), (b) collect calls could not be made, and (c) she could not be connected with an AT&T operator. I've run into several COCOTs that have an annoying habit. They're all owned by "Tele-America." Their COCOTs want $.85 to call my number, although they'll call other numbers in my building (with other CO prefixes) for the traditional $.20. Calls to their repair service (211 of all things) yield nothing but a ringing phone. Calls to the listed 800 number for Tele-America yield the same. Today I called the Public Utilities Commission.

Well, I'm not as old as the moderator, but I have worked in, and been both a subscriber and customer for both POTS and variety of special services in and around the communications business for many years. Also, I have lived in several metropolitan areas, (with different BOC's and PUC's) rather than just one. I have traveled and seen other PTTs in {mostly in-}action. Here are a few things I can comment on. They all relate NOT to the divestiture issue that Judge Greene addressed, but to DEREGULATION, which depending on your point of view, {caused, was caused by} it. 1) Local equipment: Used to be, you got a 500 set. If you wanted colors other than ebony ("We don't have black phones, that's racist" a rep told me once) it cost you extra. EVERY month. If you wanted more phones, more extra MONTHLY charges. A choice?--forget it. Memory dialer--we got card dialers (ugh) or Magicall (double ugh). PBX, you rent what we offer, period. Music-on-hold--She don't write music, you can't play someone else's on her equipment. ACD, what's that? Until the late 70's, all Bell 2500 sets came with Touch-Tone generators invented in the mid-50's. They used two special tapped, tuned, pot core inductors in an exotic circuit. Why? Because when first designed, transistors cost big money, and this circuit used one, not two. But why did they continue to build them like that for years, while other companies had hybrid and IC designs out that cost much less? If you DARED to hook up "FOREIGN EQUIPMENT" to their network, they came out and confiscated it WITHOUT A WARRANT. If you denied him (never her, unless it was an operator, then always) entrance, goodbye service. I even have copies of an old SWB employee newsletter defending this and instructing employees on how to deal with the sub (NEVER A CUSTOMER) while doing this. A friend of mine who worked for Ma designed and installed an automatic ringer_counter in several #5 X-bar offices just to detect this "ILLEGAL EQUIPMENT". Of course, I can't help but mention the answering machine. After all, it was Carterphone, (reported to be financed by answering machine companies -- Carterphone sure didn't have the cash to take on Ma in court) that broke the dike. Maybe the moderator rented (do I hear an echo?) a 1B answering machine. I never did, because I never had a big enough house. It was best described by the term "tank" as in Sherman. Of special interest to UseNet'ers would be the modem. Blazer--you have got to be kidding. You RENT (there's that word again) our 300 baud modem. If WE decide you are worthy of a faster one, we will invent it. Well, their next one was the 202, gawd help us all. Does anyone on-net think we would be here today if we still moved all the news via 202's and decvax? Look at the EUNET/EUUG situation for a comparison. 2) LD Service: In case it escaped your attention, there was a recent rate decrease. That is 'd' as in down. While we can pontificate ad-nauseam for hours about access charges, AOS, etc, when in the history of lock_stock_&_barrel Bell was there a decrease? Plus, I can call from any local phone and pay direct-dial, not "credit card" rates. In those good_old_days, such calls cost about 3x as much. If I get po'ed at my carrier, I can change, just the same way I can buy a Ford instead of a Olds. Such freedom of choice is important. Ask anyone who has bought a Lada, for example, if they would not have preferred a Nisson. The moderator has extolled the virtues of PC Pursuit several times. Would IT be around if we were still single-sourced? About the only thing that drove Ma to upgrade their LD network was when a blind student figured out She was stupid enough to set up the calls on the same path used to talk on. All of a sudden CCIS was the hottest thing since Hula-Hoops. If it wasn't for Hi-rise Joe, we likely would still listen to MF on every call we make. Along the same topic, I had a couple of friends that were foolish enough to get mixed up in such toll fraud. (Being in love seems to drive even the most sensible people to do crazy things. Being such and poor too, is even worse.) When caught, Ma wanted two things from them. First, how did you figure it out, and who have you told? Agree to tell no one else. Second, pay for the calls. If broke, pay a little per month, but tell us item one NOW. Only when they stalled on item one were they threatened with criminal charges. Ma's only interest was her fear others would discover her shortcomings. 3) Special Services I no longer have an active role in this end of the business, but do have friends that are involved. While it hasn't gotten a lot better, it has improved somewhat. Now at least the man at the board does not go into shock when you talk about 'your' equipment on his line. You can find someone who at least has some idea about what's going on. I clearly remember trying to get the rep. to explain the difference between 3003 and 3004 (I believe those were the numbers) grade leased lines. They had the same specs, went the same place, got the same loading treatment, etc. But one was twice as expensive as the other. He had NO idea, but would not admit it. In my most active days as a special service subscriber, I used to have to buy Christmas cases of brew for two local and one Long Lines testboards so they would break the rules and talk to me about the problems. The big change is not in the equipment area, but rather in outlook. The people, albeit slowly, are learning a customer is far more important that a subscriber ever was. My engineer friend surprised me. He was *happy* about it. He could go out and buy things from NEC that solved problems the KS equipment had been unable to handle. He no longer had all of New Jersey looking over his shoulder. He could go fiber now instead of 'real soon now' if he needed it. In short, competition has been good for our communications system. Sure there are new, different problems. But since Mussolini, the trains never run on time anymore, either. If the moderator really relishes those great old days of monopoly control, I STRONGLY urge him to go live in (or at the very least make an extended visit to) a European (or Latin American) country, or even better Cuba. Call the PTT. Get an answering machine, order call waiting and Star-whatever service. Obtain a Mitel PBX. Set up a UseNet site and call your feed every day for 7.2 meg of news. Then come back and tell us about it. What do other TELECOM reader think? Have you seen ANY improvements since D-Day? (By the way, who did say you installed those terminal boxes in your basement?)

The operator was not intrested in my troubleshooting except for whether or not I had checked to see if all the phones were on the hook. Then I had to guarentee that someone would be home in case they had to come out. Two weeks ago I lost dial tone. From a neighbor's phone I told repair "At the network interface ther was no dial tone but there was voltage."(PERIOD) Operator said "Can I have a phone number to reach you in case we need to talk to you?". By the time I walked home the phone was fixed. No hassles of someone staying home "just in case". My NTI is outside so there is no reason for me to sit at home waiting. 2: I wired my house when it was built (about 5 years ago). I included enough wire (4 pairs) to handle most possible wiring schemes. The wiring is run in a star configuration with the terminus in the basement (it's a full basement). I have used the wiring for an intercom also. Sure Bell could have wired it this way way back when but do you think they would have let me used the extra pairs for my own purposes. If they had they would have charged me a monthly rate just to use the wire in my own house! Worst of all can you imagine how much it would have cost for them to run the wire! I could go on with examples of what things would be like it Bell still had the same amount of control but I assume you can extrapolate those conditions to now. It appears to me that those whining about the "Good Old Days" have one specific complaint that might not have existed under the old ways (i.e. problems due to antiquated wiring, finger pointing, etc.) but then forget about all the additional problems that existed (or would have existed in today's communications environment) cause by all that excess baggage. This whinning reminds me of the person complaining about the paving of the roads because it causes the horse's shoes to wear out faster. The break up forced the communications system to become more modular. Some of the problems of modular systems are the inablility to "fine tune" and finger-pointing amoung the caretakers of the modules however an extremely fine tuned integrated system can only grow so big before it fails under it's own weight. IMHO the time for the breakup was right. It clearly opened a logjam of improvements. The whiners fail to see the vast number of small improvements as being better than some small set of additional problems created. As these improvements become more apparent and the new problems are solved (or die a natural death) maybe then they'll shut up. 1981 - IBM PC - It doesn't support CP/M, no software available, no hard disk, 160K floppy -- don't buy it. 1984 - Mac - It doesn't support DOS, no software available, no hard disk, 128k memory -- don't buy it. 1988 - Next - It doesn't support Mac, no software available, no floppy disk (????) -- don't buy it.

That was true several years ago, but BC Tel changed the entire province over to the "standard" 1+ dialing in 1985, just in time for Vancouver's Expo '86. Prior to mid-1985, directory assistance was 113, repair was 114, and (at least in my exchange, 604-853) the number that got your own number spoken back to you was 117, and the pulse/tone speed/frequency test number was 110 (I'm 92% certain of the last two). Now we have 411, 611, 211, and 311, respectively, just like everybody else (except Washington :-) I missed the original article (or maybe it just hasn't arrived yet :-), so ignore the rest if I sound incoherent. I know the Seattle, WA PBS station (KCTS) has an office in Vancouver, BC to handle its BC subscribers (apparently quite a few). If there are two 800 numbers shown, one is likely for the Seattle office, the other for the Vancouver office. (Aside: Is it possible to have a single 800 number route you to the closest Canadian or American office depending on where you're calling?) KCTS would definitely know about the BC change to 1+ dialing, so maybe you were discussing WTVS, the Detroit PBS station that's just became available to some Vancouver cable subscribers.

From time to time, including even fairly recently here in the TELECOM Digest, people make observations about how large a toll-free region they are located in, or about how much more fortunate somebody else is in being in an especially large one. Those observations made me wonder: has any ever attempted to determine the size of toll-free regions and list the largest ones, much as lists of the largest cities or SMSA's are done? It sounds like it might make an interesting paper or project for a telecom course; it might even have practical value. Note that the question is not as well-defined as it might first appear: each of the terms in "toll-free region size" is ambiguous and has several reasonable meanings. To simplify things a little, let us start by defining "local call" as follows: exchange B is a local call from exchange A if making that call using typical non-measured residential service adds nothing to the bill. (In locations where there is an optional higher level of service that I think I have seen called "metropolitan" service or something like that, assume that the residence is paying for that higher level of service, i.e., has chosen the broadest "normal" service it can.) "Toll-free region" then has at least three meaningful definitions, one of which I'll call "compact toll-free region", the second "local toll-free region," and the third, "extended toll-free region:" Compact toll-free region: Let R be a set of exchanges. R is a compact toll-free region if and only if for all exchanges x and y that are members of R y is a local call from x and for all exchanges z that are not members of R, there exists at least one x in R such that either z is not a local call from x or x is not a local call from z. In short, a compact toll-free region is a set of exchanges such that any two exchanges in the region are local calls from each other and that all exchanges outside the region are non-local calls to or from at least one exchange in the region. (I don't know if "local call" is always a symmetric relation: are there cases where A is a local call from B but B is not a local call from A?) Note that, in theory, different compact toll-free regions can overlap. Local toll-free region: for each exchange x, find the set of all exchanges y such that y is a local call from x. Each such set is a local toll-free region. This is probably what a person means when he talks about the size of the toll-free region he is in, since, in short it is the set of all exchanges *HE* can reach toll-free. Extended toll-free region: Define the relation is-linkable-to as follows -- given two exchanges x and y, x is-linkable-to y if either, a) x is a local call from y, b) y is a local call from x, or, c) there exists an intermediate exchange z such that either x is a local call from z or z is a local call from x and z is linkable to y. It can be seen that is-linkable-to is an equivalence relation over the set of exchanges. The set of equivalence classes under that relation define the set of extended toll-free regions. In short, two exchanges are in the same extended toll-free region if an appropriate sequence of all local calls could be used to pass a message, e.g., using uucp, between customers in the two exchanges, noting that if "local call" is ever non-symmetric some of the calls may have to be initiated by receivers rather than senders. (An obvious first question here is: is there in fact more than one extended-toll-free region, i.e., are there in fact at least two areas where you "can't get there from here?") The hypothetical term project then is: a) identify all the compact, local, and extended toll free regions. b) rank the three lists of regions by geographical area covered, number of telephone numbers covered, and population covered. Has anyone done any of this? Any ideas short of looking at every telephone book in the country how someone would proceed? (I'm not intending to carry out the project, only curious as to whether it could even be done.) ------------------------------ From: Syd Weinstein Subject: Repair Service Turnaround Date: Tue, 26 Dec 89 21:54:16 EST Reply-To: syd@dsi.com Here in Bell of PA country, repair service varies by the type of line. For businesses, it is usually <4 hour response for first contact, counting business hours only. However, all data lines, including normal lines terminating in RJ45's, are two hour response lines. That is, they get someone on site within 2 hours, 24 hours a day, 7 days a week, or at least damn well try to. The other week, I lost a pair, and called, within 15 mins I had a call back from the tester (who was very knowledgeable), and stated, with appology that it would be sligtly more than 2 hours before the next person could get here to fix it (about 1/2 hour late), was that ok, or should they expedite it? I said, OK, and someone was here within the 2 hours anyway, with the problem already fixed (it was a bad pair in a feeder line). No questions about did I check it, or charging if no problems, just an immediate test on the in-coming call, and 15 mins later a call back to schedule with the trouble isolated. This was at about 2 in the afternoon, on a weekday, but I have had the same service at 3 in the am on the weekend in the past also. ===================================================================== Sydney S.

No it doesn't; the new decade doesn't start until 1991. [Moderator's Note: If there is anything that can provoke as many or more replies than Caller*ID or my messages on His Honor, it would have to be the every-tenth-year debate on 'when does the new decade start?'. The theory is, since we did not have a year *named* Zero, the first decade was the years 1 through 10; the second was 11 through 20.....the 199th is the years 1981 through 1990. But this overlooks the fact that even though we did not refer to the year before year one as year zero *we still had a chronological year pass by*. Some people say we went immediatly from the year 1 BC to the year 1 AD; but I would remind you that in the 'BC years' the people did *not* think of the year in those terms; they called it by some number or name, but 'BC' was not part of the title. Many scholars believe that the person for whom the renumbering was done, whose birthday was celebrated a few days ago, was born in the year 4 BC....in other words, four years *before he was born*....so calendar mixups are not unheard of; witness the fiasco a few hundred years ago when several days had to be dropped from one year to compensate for extra leap year days which had been inserted in error; and the fact that in the colonies, we defied the old world, and refused to change our calendar for several more years. So why don't we bite the bullet and admit that the early days of our present year numbering system were not without some flaws in the methodology, write off the missing zeroeth year and celebrate a new decade this weekend.

Landry" Subject: Novice Cellular Buyer Condensation This is a condensation of the information I received in response to my queries about cellular phone service. Thanks to all who replied. In the following, some words are my own and some are from respondents. All the mistakes are mine however :-) >1) Do the Bell Companies actually own the cells? Two cellular companies operate in each geographic area. Theoretically, one is a wireline, and one is a non-wireline company, but this distinction is not always the case. The Cellular companies call these companies the "A" (non-wireline) and "B" (wireline) carriers. Each carrier operates their own cell hardware (towers, etc.). Cellular phones can communicate with either carrier-type but most phones will allow you to restrict use to one type. This setup was an effort by the FCC to have some competition without all out chaos. The wireline license normally goes to a (the) large wireline carrier in the area. The non-wireline license is issued via a lottery. >2) What is all the hubbub about subscribing with a certain carrier? > What are the differences between different carriers? > What questions should I be asking to find the right carrier for me? The major differences pointed out to me were roaming agreements, coverage in the priciple service area, customer service and rates. Each company has agreements with other, adjacent cellular providers. Leaving your primary service area is called "roaming". The roaming agreements specify what rates you will pay when using the adjacent systems. Also, manual intervention is sometimes required, sometimes not, when leaving your primary cell area. This is obviously very important. The cellular companies' coverage in the principle area can be quite different. For instance, in my area one carrier has 400 ft towers and the other 300 ft towers. When talking to some of their customers I found that this made a significant difference in reception in my hometown which is about 20 miles from the main city where the cells are. Straight out you should ask each carrier why you should subscribe with his service instead of the competition and then do your homework to figure out how much of it is tru. I found that talking to current customers was very informative. Especially concerning coverage area. >3) What is the maximum power (watts) cellular phones are allowed to > transmit? What kind of power can I expect to find in the consumer > market? Well, seems I struck a nerve here. From what I have been able to gather, the maximum power is 3 watts. Most car and shoulder mount units output 3 watts. Handhelds are normally MUCH less ( < 1 watt ). Also, the cell hardware constantly adjusts the power output of your phone when is use to use the least amount of power necessary to maintain a good signal. >4) How can I get my hands on a cell map? Some carriers, I discovered, will readily provide you with a map indicating the coverage area of their cell hardware. Others say they don't publish such maps and would rather you ask, location by location that you are interested in, and they will tell you whether that location is covered. There are companies (third parties) that publish nationwide maps. I don't have any names. It was also pointed out to me that geographical features radically affect coverage area. I was also told that the carriers' equipment is highly directional. I had figured that out from the maps I had seen. This is another reason that two carriers, with nearby cells, will have radically different coverage. Motorola published a nationwide map in 1988. I saw a copy. It was published much like a road map. It may have even been from Rand-McNally. (sp?) Anyway, I don't have a Moto cellular retail office in my city so I didn't look for a 1989 copy. >5) Anything else a novice should know before purchasing? I got a few suggestions here but mostly stuff I have covered before. The questions I asked where apparently what I wanted to know. The bottom line is that with this information and minimal good shopping practices on the buyer's part you can make an intelligent purchase and feel like you know what's going on. If there is anything I hate it is feeling like I don't know anything about something I am buying. Well, I hope this helps some out there. It sure helped me!!

An isotropic radiator's pattern *is* a uniform sphere; a 1/2-wave dipole is more like a doughnut with a really small hole in it. (The dipole "threads" the hole. That is, the maximum power from a dipole is broadside to the antenna.) A 1/2-wave dipole has (I think) about a 3dB gain (factor of 2 power gain), due to the fact that it doesn't "waste power" radiating off the ends. Even a 1/4-wave whip has some gain (as long as you hold it "up" and don't actually point it at the cellular site!). A properly phased stacked array of a ground plane plus 1/4-wave plus 1/2-wave (which is what I think you're calling a 5/8-wave, which is *about* what it is after the account for the shortening due to the loading-coil effect of the phasing coil between the two sections) has an (advertised) gain of about 5dB, or a power gain of 3.2 or so. This is how Radio Shack et al. get away with calling a 1/2-wave whip (the funny thing which is really *center*-fed 'cause the bottom half is the folded-back shield of the feed line) a "3dB gain" antenna, even though ita gain is barely a dB or so more than a 1/4-wave whip. It's 3dB with respect to an *isotropic* antenna. Rob Warnock, MS-9U/510 rpw3@wpd.sgi.com rpw3@pei.com Silicon Graphics, Inc. (415)335-1673 Protocol Engines, Inc. 2011 N.

I believe it requires two twisted pairs to each phone within the house. I wonder whether my current house wiring of standard four conductor cable to each modular phone jack will be adequate, or will the wires have to be replaced with special controlled impedence wiring when I order ISDN? I think the short length of straight non-twisted wire from the lightning protector to the phone jack is short enough to allow reflections to be kept to a minimum, hence allowing the digital signal to be received and transmitted properly. ------------------------------ Date: Wed, 27 Dec 89 01:44:43 EST From: Theodore Lee Subject: Running Out of Area Codes? I was surprised to see in the discussion over the new 310 area code that there are only nine (or will it be eight?) left. I knew it was tight, but I hadn't realized it was that tight. What are the predictions on when they will be used up and what is the plan then? [Moderator's Note: I believe the estimated date when all existing area codes *as we know them* will be used up is 1995. I think 1993 might be a better estimate. From that point on, area codes will resemble prefixes, and dialing 1 before long distance numbers everywhere will be mandatory. I've heard there is some consideration being given to also using 300-400-500-600-211-311-511 for area codes. That might stretch the supply another year or two, or even get us to 2000. There is nothing official on the use of the double zero or double one numbers at this time.

Over the course of a - year, discontinuing tone dial would offset approximately two months - of the basic non-residential service.

I have never had or used tone dial services on egsner or my voice lines. (I rather refuse to pay for some thing, such as touch tone service, that doesn't cost the phone company, and that I don't use.) Egsner communicates just fine with it's neighbors in Dallas/Ft Worth using pulse dialing. I have never had a dialing problem, and the slight delay caused by pulse dialing is hardly noticeable. As a side note: When I ordered service for my new home, I ordered two lines. The service rep asked if I wanted tone service to which I replied no. They then asked (paraphrased) "Doesn't the computer, since that is what you are planning to use on your second line, need tone service to dial?", to which I replied (again, paraphrased) "no, I have never used tone on any of my modems" I could hear the disbelief over the phone..

We have noticed in many operating regions around the eastern part of the nation that business rated service has an essentially 'unlimited' number of forwards, whereas residential service is limited to one forward. Further, orders for Remote Call Forwarding (TM), as pointed out previously, do allow the customer to specify the maximum number of simultaneous forwarded calls in many operating companies (even some satrapies :). Clearly, it is in the operating company's best interests to keep that number as low as possible to conserve resources, so don't be suprised that this wasn't eagerly offered to you if you recently ordered RCF!

More pictures show a woman using it at a clothing store to buy stuff, and another showing a man using it at a payphone and touch-toning the number. The brochure says the one number on the card does it all. I though that I MUST be missing something, so I called Sprint customer (dis)service to find out what the scoop was. They said that as far as they knew, the brochure was right - one number does it all. I asked them how they planned to provide security if every merchant and their employees where I shopped knew my calling card number. They said it was secure; since the back of the card is not copied onto the carbon, they would not know the dialing instructions! I mentioned that I'm sure that someone posing as a customer would have no problem getting that information from their operators or customer service people. The response was that they don't give out dialing instructions to just *anyone*. They verify name and address first. I know that I'm going to sleep well with them looking after my account so diligently. Perhaps they figure that the 2% or whatever they're going to pocket off of the purchases will cover the fraud losses. Sounds pretty stupid to me. Any thoughts? ------------------------------ From: "Jerry Leichter (LEICHTER-JERRY@CS.YALE.EDU" Subject: Caller-ID Segment on ATC Date: 29 Dec 89 05:03:16 GMT Organization: Yale Computer Science Department, New Haven, Connecticut, USA All Things Considered ran a piece on Caller-ID services tonight (Thursday, 28 December). There were interviews with Telco people and with someone from an organization concerned with privacy. Most of the things mentioned have been discussed many times here. The problem caused by Caller-ID that got the most discussion, however, has not really drawn much attention here - but has quickly made itself known in New Jersey, which is at the forefront of the debate. It is common for people working with possibly-disturbed patients, ranging from doctors to social workers, to have unlisted numbers. In addition, however, many of them must be reachable by their patients in an emergency. The usual mechanism such people use is an answering service; they then return the call. Of course, with Caller-ID, the "unlistedness" of their number is quickly lost. Such calls are by no means uncommon - my sister, who is a surgeon, had to give up her listed number after repeated abusive calls from someone she treated in an emergency room. Now no patient gets to call her at home, period. The telephone company's representative presented some ways out of this. Some were absurd - call from a friend's phone (right, let a psychotic patient get your friend's number, YOU'LL sleep fine), call from a pay phone (emergency calls usually come in the middle of the night), etc. The rest - e.g., get a second phone line - all had one common thread: They involved the person involved shelling out more money to, you guessed it, the phone company. BTW, the piece as a whole was fairly balanced; if it leaned either way, I'd say it was toward the Telco's: Their speakers seemed to get more air time, and there was a lot of "gee wiz, look at the neat things this allows" to the piece. -- Jerry [Moderator's Note: There is however, something to be said for the idea that if you can call me at home, I can call you at home -- if you don't want calls at home, neither do I. Attornies often fit in this category: they want *my* home number so they can work at home at night; when I ask for theirs, they say 'I don't give it out'. Neither do I, pal. They take calls at the office; so do I. In this respect, Caller*ID helps even the score a little in favor of us peasants, doesn't it!

There are a few devices out there that work with distinctive ringing service. This is where for a few extra bucks a month, the phone company assigns more than one phone number to a line, each with distinctive ringing. A detector on the line can then route incoming calls to a telephone, modem, or FAX, based upon the ringing cadence.

Maynard Organization: Confederate Microsystems, League City, TX Date: Thu, 28 Dec 89 22:33:39 GMT I would submit the Houston metropolitan area as one of the largest toll-free regions, both in population and in area... The central zone and first and second-tier exchanges (what's the difference between central and first/second-tier, anyway, in this context?) make up a compact toll-free area, by the definition given: all calls involving two phones in this area are local. This area is bounded, very roughly, by a circle forty miles in diameter, and includes most of the Houston SMSA. The normal toll-free area for someone inside that circle is bounded by a rough circle about 60-65 miles in diameter, and includes anything that could remotely be considered a suburb of Houston, including Katy, Richmond/Rosenberg, League City, Baytown, and Tomball, extending well into Montgomery, Galveston, Waller, and Fort Bend counties. The normal toll-free area for someone in the parts of this zone outside the central 40-mile circle is that circle, and all exchanges adjacent to the caller's exchange. (I was disappointed to discover that my parents, who live in Tomball, are a long-distance call from me in League City, even though we both have metro service.) The extended toll-free area is the same as the local toll-free area for the central zone. There is precious little territory in the 713 area code that this does not include.

As an added bonus, you can forward it to another number (in a different switch) and forward that other number back to it, and call either, and hear endless clicks as the call gets bounced back and forth, eating up more and more trunks (or whatever they use for interoffice calls these days..). [Moderator's Note: If you are correct in this, then I would say there is a very serious problem there; one that MichBell should correct. You can cross-forward here in Chicago, but the call forwards only once in each direction and rings through.

Joe is a very real person who attained urban legend status. I worked with Joe for several years and can assure everyone that the stories told about him are true. Yes he did call the Kremlin and he also worked for the phone company for a few years. Ma Bell wanted to put him in jail but one of the local companies hired him anyway. Joe performed a valuable service by using his uncanny ability to hear his way through the network and "find" trouble spots and routing errors. Let me share a few quick first hand stories about Joe. Joe would call the 904 Data Test Center late at night and ask to hear the tones used to test modems. In no time at all he could ID any modem and could tell if it was within working limits. Joe paid for and hosted his own radio talk show. One night I challenged Joe to a test. I would sent 1, 2, or 3 frequencies over the line and he was to tell me what they were. Without error he could correctly ID any and all combinations within a few Hz every time. Joe collected door bell sounds. When you talked to him on the phone he would ask you to ring your door bell. From that time on he could tell who was calling by the sound of the door bell without the calling party saying a word. Sadly Joe left the company after a few years. As I remember it was one of the most unselfish motives for leaving I have ever heard of. He left so that a friend of his with greater needs could take his job. I have not included Joe's last name or the company he worked for in the hopes that his legend is spread from town to town and that his true love for his fellow man and the network spreads with it. I've left much unsaid so that others can share "HIGH-RISE" stories with us if they want to. Seasons greatings to all and best wishes for the new year!

There exist COCOTs now that let you enter a Visa card number from the keypad, so I don't see that the increased fraud possitilities are all that great. If they have trouble, a straightforward possibility would be to reqire the Visa card's PIN, the one that you use to to get a cash advance from an ATM, for phone calls. There are also at most airports phones that will accept any common credit card and charge calls to that card using any of the usual LD carriers including Sprint. The card number is send as a long string of DTMF digits which you can hear while waiting for the call to start ringing; for all I know you could dial the same thing from any other phone and charge Sprint calls to your Visa card now.

Organization: Segue Software, Cambridge MA Date: 29 Dec 89 11:15:07 EST (Fri) From: "John R. Levine" I don't know if this counts by whatever rules one wants to use for determining toll-free regions, but if you have a cellular phone in New York City or northern New Jersey, any call to 201, 212, 718, 516, much of 914, a little of 203, and soon to be 908 incurs no toll charge beyond the usual per minute air time charge. There appear to be cases where it's cheaper to make a cellular call than a regular one, e.g. from Toms River NJ at the southern tip of 201 to Montauk at the eastern end of 516, a distance of over 100 miles. This seems to be true of both the A and B carriers. ------------------------------ From: Dick Jackson Subject: Re: ISDN In My Ole House Date: 29 Dec 89 16:33:13 GMT Reply-To: Dick Jackson Organization: Citicorp/TTI, Santa Monica In article <2440@accuvax.nwu.edu> hui@joplin.mpr.ca writes: >X-Telecom-Digest: Volume 9, Issue 598, message 3 of 9 >Lucky us in this city are slated to get ISDN in two years. >I believe it requires two twisted pairs to each phone within the >house.

This whole subject has been puzzling me. The standard model for premises ISDN is an NT1 hooked to a station via the two-pair S interface, or to multiple stations (up to 8) via a passive bus version. Since most homes now have multiple phones, the first thought is to have passive bus wiring. But each station is different logically I believe and only one phone can use a B channel at a given time (no "conferencing"). Unless I have some deep misunderstanding, it seems that the simple model will not serve a multi-phone house very well. I suspect that in practice people will choose to buy NT12 units. The NT2 portion of these will effectively be a PBX and in addition can support an R interface (one pair analog) to existing POTS phones for those who don't want to replace all their current phones with $500 ISDN sets and also rewire their homes. Such NT12 units are likely to be expensive, especially at first, and this is another reason why I am pessimistic about ISNDN service catching on for residential use.

The fear was that when she returned the call, she would be giving away your unlisted number, perhaps to some mentally-ill person. THIS SEEMS LIKE A VERY VALID COMPLAINT. It occurred to me that the answering service should then also offer the service of forwarding her call back to the patient!!! [Hopefully, the added cost would be minimal, since presumably the major cost of the service is the human interface]. Also, perhaps people could subscribe to such services if they wanted to maintain their privacy. The call-forwarding would hopefully keep a log, available under suitable safeguards. Consequently, obscene callers would not be able to hide. Ideally, then forwarding service would display on the receiver's in a manner that would be recognized for what it was, and the receiver could then process the call as desired. This solution might server to solve everyone's complaints [but I'm sure someone will find fault :-) ]. Standard disclaimers apply + I a software person, and only a guest where I work.

So if someone, somewhere, can find a potential disadvantage with a new way of doing things, we should immediately remove that thought from consideration? If a new service or invention won't improve your life, no one should benefit? Can you substantiate harm caused by Caller-ID? It does exist in the world; it should be a simple matter to pull up some case histories. Someone explain why I, JMH, should not be entitled to see the number of those people who call me. Don't tell me about whackos and criminals who might abuse the system; I'm not one of them. Don't tell me about big business and government; they already have access to these numbers. Saying that some of us shouldn't have this technology because others might abuse it is akin to saying that no one should have computers because some malicious hackers might cause trouble, or that no one should have automobiles because there are irresponsible people who will drink and drive and kill people (a much more compelling argument than any against Caller-ID, IMHO).

But you are the first to bring up some well-thought-out and legitimate privacy concerns. Heretofore we have been subjected to every conceiveable privacy non-sequitur, from wife-beating to IRS fraud. Previous comments provided no reasons whatsoever for considering the privacy issue; yours did. In my previous post on the matter, I invited legitimate concerns, as opposed to what we had been subjected to so far. >Higdon does not expect his phone number to be private. Here, I will take issue with you. I have *many* private numbers and I expect them to remain so. But I am prepared, in a world of Caller-ID, to take the necessary steps to keep them private. In other words, I will take the responsibility for maintaining my privacy, not by denying the rest of society the advantages of Caller-ID, but by taking prudent steps to make sure that none of these numbers appear on an undesireable display. This can mean watching who I call with what line, or even how I handle incoming calls when I know that my number has been compromised. But do not simplistically dismiss me by saying that "Higdon doesn't care about his privacy". That is absolutely wrong. But maintaining my privacy is my responsibility in any environment, and not that of some utility regulator. John Higdon | P. O.

I've been faxing email for people for many months, and one problem which recurs is people supplying me with incorrect fax numbers. I usually try a voice call first, to ensure that the destination phone number is indeed answered by a fax machine. Occasionally it is not, and I am forced to confuse the innocent person who answers. Often, the person can supply me with the correct fax number. This problem is compounded with fully automated computerfax systems. Some computerfax hardware is able to detect voice on the line, and hence "do the right thing": don't call again, and return an error. Some computerfax systems do not properly detect voice, and they might redial the phone number N times before returning an error. One solution might be to use computerfax hardware that has the capability to play digitized voice and ask the recipient to press touch tones to indicate his annoyance level! Most computerfax hardware does not have this capability, unfortunately. A risk is that blue network meanies would purposely ask for a fax to be delivered to a non-fax number, in order to cause an "annoyance". Annoyance calls are illegal. I wonder whether the computerfax machine owner is liable for such calls, or whether the sender is responsible? (comp.dcom.telecom cats can probably answer this question.) We've seen the uproar in Washington about junk faxes... Computerfax opens the door for an email user to cause junk fax, intentionally or unintentionally. ; Steve Elias ; work phone: 508 671 7556 ; email: eli@pws.bull.com , eli@spdcc.com ; voice mail: 617 932 5598 ; ------------------------------ Subject: Automatic Ordering/Automatic Pranking Reply-To: John Higdon Organization: Green Hills and Cows Date: 28 Dec 89 20:30:20 PST (Thu) From: John Higdon Quote from my latest Pac*Bell bill: "Now you can order Commstar Features* automatically -- anytime! Place your order for Call Waiting, Three-Way Calling Speed Calling/8 or Call Forwarding 7 days a week, 24 hours a day. Interacting with this computerized system is easy -- just dial 811-7050 from your touch-tone telephone. WE'RE MAKING THINGS EASIER sm * Commstar Features are available in most areas. ** You may have to dial a "1" before dialing this toll-free number." After playing a little with Pac*Bell's automatic custom calling feature ordering, I feel that it's an idea whose time should never come. What would stop me or anyone from ordering every feature on the accounts of people we don't like? That's a rhetorical question since the answer is obviously nothing. The session goes something like this: You are welcomed to the service and are told to take a powder if you have a rotary phone. Then you are asked for the area code and number of the phone that the order applies to. You get a list of the features and are told to enter the numbers of the features you want turned on. The voice then reads back the features you selected, then give you the one-time charge and the monthly charge for the features you ordered. The safety may be in the fact that Pac*Bell now confirms by mail all orders. If, however, the "victim" is out of town, then he will find new features on his telephone when he returns. Or at least new charges on his bill. The only other protection would possibly be to record the caller's (person who places the order) number, which is quite possibly what's done. The number (811-7050) rings into a DMS which give three ringbacks then no-answer-forwards to something else. The calling number would be available to the system from any FGD compliant office. When I tried to use the system to order on one of my own lines, it wouldn't accept the order. This could be because: 1) My accounts are passworded or 2) all of my lines are Commstar II-equipped (mini-centrex). I wish Pac*Bell would put its energy into real stuff like CLASS... John Higdon | P.

I think 1993 > might be a better estimate. From that point on, area codes will resemble > prefixes, and dialing 1 before long distance numbers everywhere will > be mandatory. ... Presumably by "long distance" he meant here "to another area code". The thing that most distresses me about this whole area-code-exhaustion business is that it'll mean that we'll LOSE the possibility of a leading 1 ACTUALLY meaning, as it still does where I am, "long distance". Here, we dial NNX-XXXX for local calls, 1-NNX-XXXX for long distance within our area, and 1 + 10 digits for other area codes (I'll call this "Syntax 1"). Now, we're about to run out of NNX prefixes in 416, which means that the 1 + 7 digits syntax becomes ambiguous and has to be dropped. Bell Canada then has two options. They could drop the "leading 1 means long distance" rule, and we'd dial 7 digits within the area no matter whether local or not, and 1 + 10 digits outside ("Syntax 2"). Or they could drop the "no area code required within area" rule, and we'd dial 7 digits for local calls and 1 + 10 digits for long distance no matter whether within the area or not ("Syntax 3"). Bell Canada has actually elected to go to Syntax 3, and I personally am most pleased that they have done so. (The effective date is sometime in March, I believe.) But it appears to me from reading this forum that Syntax 2 is rather more common in other parts of North America. In Syntax 2 places, you have to know which prefixes in your area code are local calls and which are not -- or in some cases, the sharp division of calls into local (free) and long distance (not free) doesn't exist. Of course Syntax 2 does have the advantage that it can be used where the local calling area is larger than the local area code. To be complete I should mention Syntax 4, which I think was formerly common and is becoming rare: leading 1 is never used, and one dials NNX-XXXX for any call within one's area, 10 digits for calls to other areas. It only works in areas where all exchanges are NXX. And finally, there are the variants of Syntax 1, 2, or 3 where the leading 1 is replaced by some other access code, such as the 112 mentioned as having been used until recently in B.C.; I remember that Toronto used to use 112 about 20 years ago, too. Now, finally, my question. Can anyone comment on the relative prevalence of the four syntaxes that I have called 1, 2, 3, and 4 in North America, or better yet, actually provide a list of what areas use what syntax? (Note: My interest here is in major operating companies, not, say, Pinnacles.)

A little digging reveals that it is not a business/residence matter at all. It is simply a matter of feature implementation in the various switches/generic software releases. When the feature was first generally offered, it allowed unlimited unconditional forwards. When it was found that two numbers forwarded to each other could wipe out the entire trunk bank between the two switches, the generic was modified to allow only one forward. Later, it was realized that simply requiring each call to be supervised before the next was forwarded would prevent a trunk-gobbling loop and this change was folded into the 1AESS generic. My office CO has a 1AESS running the very latest generic (CLASS capable, I'm told) and can multiple forward, while my residence is "served" by an old rusty 1ESS running shareware (I'm told it's actually capable of connecting two telephones together, sometimes) and forwards exactly one call, period. > hear endless clicks as the call gets bounced back and forth, eating > up more and more trunks (or whatever they use for interoffice calls > these days..). If you can actually do this, it indicates that they are running a positively *ancient* generic and deserve to have all of their trunks disabled by pranksters, which I'm surprised hasn't happened already. If that were possible here, the trunks would be gone in an instant because of the SS#7 signaling employed. John Higdon | P. O.

A forwards to B; B to C; and C to A. Calls to A ring through to B regardless of B's setting; calls to B ring through to C regardless of C's setting; and calls to C ring through to A regardless of A's setting. Somehow the call takes information with it saying in effect, "I am not really a call to B, I am a call to A only reaching B by virtue of forwarding, and how do we know A wants to really wind up with C ?".... The other generic operating here will chain-forward some absolute maximum number of times: this can be straight forward, A to B to C to D, or it can be in a circle, A to B to A to B to A, and at some point when it sees it is getting nowhere and is unable to ditch the call someplace then it quits and returns re-order to the original caller.

Don FOR RELEASE WEDNESDAY, DECEMBER 20, 1989 BASKING RIDGE, N.J. -- AT&T is making it more convenient than ever for shoppers to do business through 800 numbers: now customers can find suppliers or vendors faster by calling up the 800 directory on their computers. By agreement with CompuServe Incorporated, AT&T's directory of 800 service numbers is available now free of computer connect time charges via CompuServe Information Service, the world's largest online information service for personal computer users. "Although this is not a foray into electronic publishing for AT&T, it is a unique form of electronic directory assistance," said Cliff Holtz, AT&T's district manager, 800 services. "Right now, it's the first 800 yellow pages directory available through a commercial online computer information service." CompuServe's 550,000 subscribers will be able to instantly retrieve the 800 directory information in their homes or offices. To reach CompuServe, members need a personal computer, a modem, communications software and a telephone. Members can use the service via a local phone call in 600 cities across North America and in more than 100 foreign countries. "We're pleased to join with AT&T to offer our members a quick, convenient way to find the variety of 800 service numbers available," said Maurice A. Cox, executive vice president of CompuServe's Information Services Division. "The directory is comprehensive in scope, but employs easy- to-use search methods." The online computer directory is an electronic version of AT&T's consumer and business 800 directories merged into one file. Users will be able to look up 800 numbers alphabetically and by subject-matter. In addition, the service will feature a special section with discount offers available only to AT&T 800 service directory users. AT&T 800 Toll-Free Directories are available for purchase in softcover consumer and business editions at AT&T Phone Centers nationwide. More than two million directories are distributed free each year to businesses and households across the country. # # # Don H Kemp "Always listen to experts.

Naturally there are those calls where you say "hello" (remember, I'm not a business) and the caller simply hangs up. But what began getting to me some time ago was the pattern that started emerging. Idiot calls to my 800 number now fall into two categories: 1. Callers wishing to reach a local (SF) ferry and public transportation service; 2. Callers wishing to reach the Hilton Hotel chain. After blowing my stack when awakened at 5:45am by a woman who said, "Isn't this ferries?" (I beg your pardon!!), I developed a new approach. The moment I realize what the person who is on the line is after, I take their reservation or give them what (made up) information they seem to be seeking. Great fun! A similar tactic is used for the Hilton callers. I used to take their confirmed reservations, but lately I have informed them that Hilton has gone Chapter 7 and that they should call 800-325-3535 for reservations at Sheraton. "Are you sure?" "Well, I answered the phone, didn't I? We're just the cleanup crew, carting stuff out of the offices." Maybe this is all a bit mean, but after all I am paying for the entertainment. John Higdon | P.

[Moderator's Note: A similar situation here in Chicago several years ago was when the Hyatt Regency people opened their new, very posh hotel. A flop house of half a century here, the *Hotel Regency* was frequently getting phone calls wanting reservations at Hyatt Regency. They took the reservations, had the customer secure them with a credit card number, and cheerfully gave out their address to the naive out-of-town callers who if they showed up at Hyatt Regency were disappointed to find their reservations had never been received, even though the charge came through on their card later on....if they showed up at the Hotel Regency, they were doubly disappointed, I'm sure. And in the few cases where Hotel Regency got sued, they won every time; they had said nothing deceptive on the phone, and they had given the address of their establishment.

It would be totally inappropriate for such a service to have callers' numbers available to it, either by 800-style ANI or by CLASS implimentation. A service such as this would be out of business in a hurry if it was discovered to be keeping records of callers' phone numbers. But just because a service isn't appropriate everywhere for everybody is not an excuse to make it unavailable to anyone, is it? Call waiting is hardly an appropriate feature for a modem line, but is that any reason to make the service unavailable to anyone? No, you use things where they are useful, obviously. John Higdon | P.

Karn" Subject: "First" BBS in USSR I was interested to read of the claim that the BBS in Estonia is the first in the USSR. This is incorrect. Earlier this year, an amateur packet radio bulletin board system was established in Moscow with the callsign RA3AT. I believe it can be accessed over HF radio through a HF/VHF gateway switch also in Moscow. Amateur packet radio technology was first known to have been used in the Soviet Union during the Soviet/Canadian SKITREK arctic expedition of 1988. Donated amateur packet equipment was also delivered to Moscow a year ago for use in Armenian earthquake relief efforts. I also know that my TCP/IP package for the PC has found its way into the USSR, so it probably won't be long until we see the first Soviet site on the (amateur radio) Internet. Maybe I can persuade them to name one of their machines "kremvax". :-) Phil ------------------------------ Subject: Re: Running Out of Area Codes, and How to Dial Long Distance Organization: Segue Software, Cambridge MA Date: 30 Dec 89 15:58:03 EST (Sat) From: "John R. Levine" The dial-1-for-money distinction was lost in many parts of the U.S. long ago. Many cities, notably New York and Los Angeles, have multiple area codes for local calls. Even here in Boston, you dial 1 for long distance except that there are a lot of exceptions where you dial 1+number or 1+npa+number but it's local anyway. What is a free call depends greatly on what kind of service you have, a call that costs nothing on one of my lines can cost 26 cents on the other (which has cheaper monthly service). Also, as I've noted before, there are places in New Jersey where you can dial any of a local intra-lata call, a local inter-lata call, a toll intra-lata call or a toll inter-lata call with seven digits. Dialing 1+area code for intra-NPA calls is a gross hack and is unlikely in the long run to retain a useful distinction between free and toll calls, although it does let them delay replacing some of those old SxS exchanges. Perhaps we need home COCOTs that tell you when you dial how much you're spending.

These numbers are supposed to be free. I have found a BUNCH of COCOT phones around Seattle that say to dial 211 for refund and 611 for repair. Often I hear the phone outpulsing a 7 digit number in response to these 3 digit codes. On many of the phones I get a response of "call cannot be completed as dialed." Our PUC has an 800 number. A call to the PUC with the location and telephone number of the phone has resulted in DISCONNECTION of the non-complying phone every time. The fellow at the PUC told me that these are usually phones owned by someone who has NO concept of how the phone system works, the legal requirements, or how to program the thing. COCOT companies that operate the phones are usually more in compliance.

Item one has some uses. Item two is very nice if you run a dialin bank, shall we say in Metro DC, with 10 modems. You can get one line, in a 'straddle' zone (maybe Howard County) and always forward calls to the bank. Then up to ten people can benefit from the extended area of local calling available. Alas, one method of squelching loops (1) is implementing a block on (2). For whatever the reason, in the areas of DC where (2) did work, it seems to no longer.

It seems to me appropriate steps are to insist that any C-ID implmentation provide per-line and per-call ways to turn C-ID on and off. That can't be hard; a previous message implied that the Bellcore spec for C-ID already has provisions for that. Few of us claim that it's a bad idea ever to provide the caller's number under any situation. But there is a long-standing presumption in practice and in law that my list of callees is private. That's why every state has laws about wiretaps and pen registers. I realize that there are cases now where the number is delivered (and I wish American Express would stop denying it) but we should be looking for coherent privacy policy, not making it by default as the technology changes.

Space forbids listing the legion of encroachments on your privacy that come up every day, that you must make an effort to thwart. But let's put it this way: if the majority of the people either aren't as paranoid as you about this particular privacy matter and/or they wish to avail themselves of this technology that you consider threatening, then it is you, my friend, that will have to bear the expense and go to the trouble to protect your minority interest. If most people don't care if their numbers are known to their callees, isn't it fair that those few who do care would have to be the ones to exert special effort. Remember, Caller-ID doesn't place your number on billboards all over town, just on some displays of *people you, yourself voluntarily call*. You still have to make the call for someone to get your number. How many people do you bother that you don't want bothering you in return? John Higdon | P. O.

Granted, you could What miserably moronic idiot thinks that without CID it is perfectly safe to hack out authorization codes for long distance? As one of the original MF blue boxing phreaks of the sixties let me say that these imbeciles give phone phreaking a bad name. Not only is their only activity sitting there and trying one code after another for the sole purpose of making free calls, but they don't even seem to realize that their "phreaking" attempts are leaving trails that look like interstate freeways at the long distance companies they are trying to defraud. When you place a call through a long distance carrier, CID or no CID, the local telco has delivered the number of the originating telephone to the LD company. Sprint, for one, has very aggressive "hacker" detection, and all recorded attempts include a phone number. Not that it was justification, but at least when we used to scoot around the world via MF, we learned a lot about the network. Some of what I know today came from those efforts. Making free calls was indeed secondary to the thrill of establishing multi-tandem connections, routing around the world to a phone on the next desk, playing with auto route/rate, talking with operators around the world, etc. Even in those days, when things were wide open, the number one rule was: never use your own phone. Jerks who hack out authorization codes apparently don't even have a clue how the system works. Those droolers are beneath contempt. > It goes without saying that phreaks (or do you say freaks? :} ) have > been among those voicing the loudest objections to CID.

Nonsense. And again, the CID wanters seem to think of themselves as vigilantes and so argue that giving THEM the number is the way to bring the forces of justice to bear. Further, in the case of phreaking, they generally call someone who WANTs to talk to them, no? So why does it matter if the person you call can figure out your number... they either already know it or you'd probably just tell them. The problem with phreaking is figuring out that it is happening, NOT figuring out where the call is coming from. I still think we would be MUCH better off with a bunch of very strict "privacy of information" laws making it _very_ hard [e.g., requiring a court order] to allow ANYONE to 'peek' into the phone company's electronic dossier; treat that information like your medical records. Everything _legitimate_ that you can do with CID you can do just as well by having the phone company manage information [and still keep it as protected as possible]. /Bernie\ ------------------------------ Date: Sun, 31 Dec 89 9:03:26 CST From: TELECOM Moderator Subject: Enuff Already Lest anyone accuse me, in my immoderation of this Digest to only giving one side of the Caller-ID controversy, I've printed several more (?) messages against my better judgment in the past month or two.

Another year past; another volume of the Digest complete. This past year has seen a growth in TELECOM Digest traffic that would have seemed very unlikely in December, 1988: 603 regular issues of the Digest this year, and several special issues, meaning a nearly three-fold increase over 1988, when there were 213 regular issues, and a four-fold increase over 1987. Per the Usenet Arbitron program, an estimated 17,000 regular readers of comp.dcom.telecom at the end of 1989, versus 9800 at the end of 1988. Several hundred of you receive TELECOM Digest via direct email subscription; the list has about doubled in size this past year. Names on the direct list are primarily on the Internet, but include about 100 Bitnet sites; and copies go to MCI Mail, AT&T Mail, Compuserve, Fidonet, Telemail, the Net-Exchange of PC Pursuit, West Germany's Tele-Box Mail, and NYCENET (a service of the New York City Board of Education). 65 'exploder addresses' or expansion addresses are on the direct mail list. These are sites which receive the Digest and automatically re-distribute it to names on their own list. I've no idea who most of these people are, or how many copies are re-distributed in this way. As much as I would like to take the credit for this growth, the fact is that the *quality of the messages and the readership* of TELECOM Digest has played a far more important role in the growth of our little journal during the past year, and for that, I thank every one of you. This Digest originated in August, 1981, and was founded by Jon Solomon, who successfully moderated the group for several years until I assumed that responsibility in October, 1988. My work has been much easier because of the reputation and foundation he laid for the Digest during his tenure. Although some readers chose to quit participating when jsol resigned, most of you who are long-term participants chose to remain, and your messages and thoughts have been particularly useful to me. And of course, chip@vector.dallas.tx gave invaluable help most of the year with the problems involved in getting the Digest out to the Usenet people. Although the rapid growth and radical changes in the telecom industry has been partly responsible for the increase in message traffic in TELECOM Digest, the fact remains that you, the readers, have made it happen. Here's to 1990, and another year of thought provoking, informative, educational and sometimes controversial reading! Caller-ID has worn out its welcome, don't you think? Let's try something else for awhile. No Digest Monday.....next issue on Tuesday morning, 1/2/90.
