To even think for a moment that a LIVE PERSON might be creating the announcement is, of course, an absurd thought. However, once upon a time, a live operator did in fact create time-of-day announcements on a demand basis. In 1932, when more and more telephone central offices were being converted from manual to dial operation, the Bell System offered their first "automatic" time-of-day announcement service. Prior to this time a subscriber could call the operator and *ask* for the time of day, but there was no generally available feature where a subscriber could simply dial a number and get the time-of-day automatically without *asking*. Enter the Western Electric No. 1 Announcement System. Calls to an access number for this system could be completed through SxS, panel and manual central offices. An operator sat at a desk in front of a microphone, behind which was small panel equipped with a few keys, lamps, sound level meter, and a special mechanical digital clock. This small panel, which was mounted in a gen-u-wine mahogany wood box, was called the Time Turret. The mechanical digital clock displayed hours, minutes, and fractions of a minute. The minute fraction wheel was divided into eight segments, each of which was 7-1/2 seconds long. The even segments were marked "0", "1/4", "1/2", and "3/4"; the odd segments were simply painted white. The most important indicators to the operator on the Time Turret were the Call Waiting Lamp and the Announcement Lamp. When the Call Waiting Lamp illuminated, the operator prepared for an announcement by looking at the mechanical digital clock. When the Announcement Lamp illuminated, the operator knew she had *exactly* 7 seconds to make an announcement which went something like: "At the tone, the time will be eight hours, thirty-four and one-half minutes". Exactly 7-1/2 seconds after the Announcement Lamp illuminated, an automatic timer would place an 800 Hz tone on the telephone line for 1/2 second. Following the tone, the Announcement Lamp would extinguish. If a caller had stayed on the line or new calls had come in on other trunks, the Call Waiting Lamp would stay illuminated, telling the operator that she would have to prepare for another announcement in 7-1/2 seconds. In larger metropolitan areas with more than one central office, a Time Bureau would be set up with a single No. 1 Announcement System handing all calls using incoming trunks from several central offices. It does not require much imagination to realize that in larger metropolitan areas the Call Waiting Lamp would probably be illuminated on an almost continuous basis, meaning that the operator had little idle time! Can anyone imagine a more boring and fatiguing job than having to announce the time of day four times per minute for an eight hour shift? The No. 1 Announcement System was specifically designed with a one-way amplifier so that the operator could not converse with any callers. In addition, the operator had a volume level meter so that she could be certain of speaking at the desired level. There were also keys to call a supervisor and operate a central office trouble alarm. The first machine-operated announcement system was the No. 3A, and it was first introduced in 1939. However - believe it or not - the No. 1 Announcement System with a live operator was utilized in some areas until the mid-1950's. As a somewhat satirical aside, best appreciated by any present or former WECO or BOC readers, consider the following: The No. 1 Announcement System did have an Unoccupied Position Alarm feature which would sound an alarm in the central office if there was no operator headset plugged into the Time Turret and the Call Waiting lamp was illuminated. However, I am rather surprised that there was no "Operator Failure Alarm" feature. After all, how would we know if the announcement operator has failed to make an announcement as a result of falling asleep, having an acute attack of laryngitis, or suddenly going stark raving mad from the mental torture of this abyssmal job? If *I* were the WECO engineer who designed the No. 1 Announcement System, I would have most assuredly installed a VOX-circuit on the output side of the announcement amplifier. If speech were not detected during the interval while the Announcement Lamp was illuminated, a major alarm condition would have been signaled! Furthermore, I would have implemented an "Operator Synchronization Failure Alarm" if speech were still detected during the 800 Hz tone interval. And, of course, there would be peg count registers for these operator failure alarms, the results of which could be used to penalize the operator's salary. :-) <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: Gabe Wiener Subject: Re: Telephone History: For Sale?

I might have just acquired an expensive taste... Ummmm....welcome to the realm of antique telephone collecting (one of my hobbies). An 11-hold strowger phone will probably run you about $1,500 if you can find one. They're quite rare and very sought after. The only way you'll find one through regular antique channels is by pure luck, and if you do, you'll probably pay $50 for it because in all probability, the proprietor will have found it at a junk sale and not know the value of what he has. I had such luck only once...when I bought a Western Electric 506 switchboard from 1918...working, with magneto, worth well over $1,000, for a mere $75. Dial service has not changed in principle since around 1892, and thus even an 11-hole strowger unit would talk to a modern switch, though you might need to put a mini-network inside. Telegraph-key strowgers, and there are less than 1,000 of those in the world, will NOT talk to a modern switch for obvious reasons :-) You can use any rotary dial phone on a modern switch pretty easily. Telephones of the '20's, '30's, and '40's, as well as payphones from that genre (even payphones with separate transmitters and receivers) are quite readily available at good prices from Phoneco in Galesville, WI). Phoneco buys the surplus from telephone companies and sells it mail order. Mostly they'll sell old phones to telephone stores who then mark them up tremendously, but they'll be glad to sell to an individual. For a nominal fee, they will also install a network and/or ringer into any phone that doesn't have it and make it work on a modern system. They have phones of all periods, from crank-magneto through modern touchtone. But it's very doubtful you'll find anything from them that's much older than a 1907 Bell System magneto wall-set (still a truly charming phone...that's the typical crank phone you see in the movies). They also have lots of surplus telephone company equipment...switchboards, rolls of wire, test sets, etc. (I got a working bell system test set (rotary) for $25 from them. One of their main trade items, however, is the payphone. They buy truckloads of them, from all periods. Besides selling 'em to phone stores and to folks who either collect them or who just want a payphone, they also do an interesting thing. They will insert a circuit board if you want that will allow an old three-slotter to function as a COCOT, all for around $400. There are other places as well to get antique telephones, such as the House of Telephones in Texas, another mail order firm. But you should keep in mind that if you want _really_ esoteric stuff, or really early stuff, there are only two ways to get it. One is to prowl the antique shops in search of a dealer who doesn't know the value of what he has (and as I said, this happens quite often). The other is to join one of the antique telephone societies, such as the Antique Telephone Collectors Association. They have classifieds galore of people looking to buy, sell and trade. BTW, speaking of Phoneco, the operator, Ron Knappen, publishes a guidebook to old telephone equipment that is the bible for collectors. In two volumes (plus a price-guide), it has pictures and descriptions of virtually every telephone made in this country (and abroad, for that matter). It also has pages and pages of excerpts about telephone history, sich as the development of the dial, the independent telephone companies, etc. A truly indispensable book that will soon itself be worth something. The stock on the book is running out, and I don't think there is quite enough demand to warrant another printing. So if you want one, get it now. I think it's around $40. I may be rambling at this point, but I hope I've provided an answer to your question. By the way, it is unlikely that Phoneco will have an 11-hole strowger telephone! :-) Gabe Wiener - Columbia Univ.

Well, if you find a source of clocks, let me know... I want one too. As to the dial, 11-hole dials were used as late as WW2 in Colins transmitters. I'm kinda surprised that a navy radioman hasn't popped up to say so. As late as 1971 my local community college amateur radio station had a surplus Navy TDH-4 transmitter made by Collins - complete with the "Autotune" option. The "autotune" used a 11-hole dial labeled 1-2-3-4-5-6-7-8-9-0-A, and the A was used to select the modulation mode. For example, to set the system to 7.255 Mhz in AM, youd dial 7-2-5-5-A-3. After about 15 seconds of "whirrrrr-clunk-whirrrrrr-clunk-ka-chunk-ka-chunk- whirrrr-clunk", etc. every stage would have been tuned. Just the thing for 90-day wonders that couldn't remember to adjust the grid circuits for a peak and adjust the plate circuits for a dip in the current meter. And don't forget to switch the meters to the stage you're adjusting! To set it to 7.055 Mhz, using morse code you'd dial 7-0-5-5-A-1. To lock it in continuous transmit on 3.999 Mhz you'd dial 3-9-9-9-A-0. The numbers were not hard to remember due to Collins adopting a standard descriptor that was already in wide use: the FCC allocation descriptions. The TDH-4 was a 2-18 Mhz transmitter, another model was 15 (or so) to 30Mhz. Autotune was available on a lot of different radios. The FCC allocation descriptions use A for amplitude modulation and F for frequency modulation. A table can be found in any edition of the Radio Amateur's Handbook, available in most libraries. Anyway, a _LOT_ of those old monsters (The TDH-4 was 6' high, 3' deep and almost 6' long - literally built like - and _for_ a battleship) have been scrapped. The dials show up every so often in surplus stores or amateur radio swap meets. I still want a WU clock.

Well, it was actually something called "75-speed" ) which indicated a maximum speed of 75 WPM, transmitted in 5-level ) "baudot" encoding. Some of these 5-level devices could actually be geared for different speeds. The most common speed for the units, if you find them today, is 45.45 baud (with 1.5 stop bits!), which works out to ~6 chars/sec (commonly called 60 WPM). ) Actually, they used a "switch" character to flip-flop between ) meanings of particular bit patterns. They used two characters. There was a "shift" character (sometimes called "figs", bit pattern 0b11111) which forced the second character set. To drop back to letters, the "unshift" character (sometimes called "ltrs", bit pattern 0b11011) was sent. As a user-settable option, the machine could also be set to "unshift-on-space", which meant that if a space (0b00100) was received when the machine wsa in shift mode, it would drop back into unshift mode. The user selection of the "unshift-on-space" option is made by moving a metal bar under the vanes. I do mean "drop" - shift mode was handled by raising the carriage so that the other row on the type slugs would hit the platen. The "unshift" got a nice gravity assist, and made a nice sound.

PT] I beg to differ. In the metro Detroit area, the Federal Government still uses enterprise numbers. The FAA uses them so that pilots at several major aiports, but are a toll call away, to call Flight Service to open or close their flight plans. They used different enterprise numbers depending on your location. There wasn't one number for everyone in the county to call. Since I use to work for the FAA at Pontiac Tower, I used to have to pass these numbers out quite frequently.

And like any good telephone joke, it strikes a chord in all of us from the industry. If you haven't worked with Special Services, you may not appreciate it fully... Did you hear about the Telephone Man who was drafted into the Army? Seems he did well enough until he got out on the rifle range. As the sergeant approaches, he notices the Telephone man has his M-16 on full automatic and is blazing away firing rounds at a phenomenal rate. There's a rapidly growing pile of spent cartridges on the ground next to him. The Sergeant lifts his field glasses to observe the accuracy of this over confident trainee, and sees absolutely no marks on the target. Now, Sergeants are painstakingly trained by Uncle Sam to build the confidence and ability of all boot camp soldiers, so the Sergeant sizes up the situation and acts: "Soldier, you've wasted hundreds of perfectly good rounds of ammuntion and a thousand dollars of the taxpayer's good money and you haven't hit the target once! What in the [several arcane military terms deleted] is wrong here?" Now the Telephone Man knows he must immediately analyse the situation and correct the problem. His years of technical training from Ma Bell are called into play: The Telephone Man looks down the barrel of the gun. Then he carefully inspects the chamber. (Probably looking for the KS number so he can refer to the correct BSP for this weapon, no doubt.) He then rams a cartridge home into the chambers, arms the weapon, puts his finger over the end of the barrel and pulls the trigger. Of course, this neatly blows off the tip of his finger.

This may very well be the way it is, but it sounds like Bad Thinking to me. In many cases, it is possible to anticipate enough future need for new telephone numbers in an area to know that allowing N0X and N1X prefixes will only delay an inevitable area code split. In New York City, only a couple of years elapsed between when they added the new prefixes (requiring 1-plus dialing for long distance) and when 212 was split into 212 and 718. Adding the prefixes did not help to minimize the number of area code splits, it only postponed a split, and at a cost. The cost I'm referring two took these forms: 1-plus dialing became mandatory for long distance calls from New York City. Before the N0X and N1X prefixes were added, New York City had dialing the way God intended it: just dial the number, with or without an area code, no 1-plus required. To make an operator-assisted local call in New York City, you must now always include an area code, even if it's your own. For example, if you're at a phone in the 212 area, and want to dial an operator-assisted local call to 802-1234, you will dial 0-212-802-1234. (Contrast this to the way it was handled in Los Angeles: the same 0-plus dialing pattern as before, no need to include the area code if it's your own, but if it's a local call to an N0X or N1X exchange, the CO will recognize this by timing out after the seventh digit of the phone number is dialed. Neither solution is elegant.) The N0X and N1X exchanges are ugly. Most telephone users hadn't ever seen them before. Telling your phone number to someone sometimes caused them to think they'd heard wrong, because they'd never seen such an animal before. When New York City's area code was split, the heart of the city (Manhattan) retained the original 212 area code. That also seemed to be the aim in other area code splits that I observed. When Colorado split into two area codes, I noted that Denver and the rest of northern Colorado retained the 303 area code, but a different reason for this was given in a newspaper article: it was said that the greater need for new numbers was in the south. This prompted me to write a letter to the Mountain Bell executive quoted in the newspaper. I've reproduced my letter and his response below. Other writers in this digest have recommended the experience of touring a central office. I add the following fun suggestion: write a personal letter to your friendly BOC CEO. Tom Ace tom@sje.mentor.com ...!mntgfx!sje!tom ================================= My letter: (303) 499-1919 710 South 42 Street Boulder, CO 80303 November 20, 1986 Solomon D. Trujillo Mountain Bell 1005 17th Street Denver, CO 80202 Dear Mr. Trujillo: I saw your name in the newspaper associated with an announcement that Colorado will be served by two area codes starting in 1988. I had noticed that when New York and Los Angeles started to run out of telephone numbers, new exchanges were created that had the form of NPAs, i.e., with 0 or 1 as the second digit. These actions only postponed the invevitable splits into 212/718 and 213/818, and left both areas with those ugly new exchanges and some awkward dialing patterns for local operator-assisted calls. I want to thank whoever was responsible for deciding not to go that route here in Colorado. I received a piece of literature enclosed with my latest phone bill, advising of the coming area code split, and explaining that the southern Colorado calling area will receive the new area code because it was in that area that the most significant growth was occurring. You and I know, though, that the northern calling area in which we live is clearly where it's at, and will retain the 303 area code because it deserves to. I do appreciate, however, the need to explain the choice tactfully, in a way that wouldn't offend those who live in the other area. Who makes these choices? Did Mountain Bell select 719 from the few remaining codes, or was the decision made by some central committee? Thanks for your time. Sincerely, Thomas Ace =================================== His response: Mountain Bell Solomon D. Trujillo Colorado VP and CEO December 4, 1986 Mr. Thomas Ace 710 South 42 Street Boulder, Colorado 80303 Dear Mr. Ace: Thank you for your letter regarding the Colorado area code split. I agree it's important to handle the transaction as smoothly as possible and with as little customer disruption as possible. I do not agree, however, on your reason for why the new area code goes to the southern area. The Colorado Springs area as our choice was really as it was stated: the area is expecting significant aerospace and other growth over the next few years. They need the phone numbers! To answer your last question, we were assigned the 719 area code by Bell Communications Resources in New Jersey. One of its central functions for the country is maintaining and assigning area codes. Thank you so much for writing. It always brightens my day to hear from a customer with positive comments. Sincerely, S. D.

Ah, but there are other reasons! Yes, folks, it's another of Macy's True Stories of Telephony (TM) We often had problems with radio/TV stations running contests and giveaways in my phone co. days...a real traffic engineering nightmare. Seems the heavy peak demand caused by everyone going off hook and dialing one exchange at once would bring the local tandems to their knees. There was even a ESS in one city I know of that would give up, shut down and re-IPL on an 85% (or therabouts) load. In the days before widespread ESS and CICS this could be a real problem. The solution devised back in the late 60's was to set up a special exchange in one switch, usually the downtown one, since it was a major tandem and most of the stations had their studios downtown. The outlying CO's (Central Office) would be set up with only a couple trunks available to the downtown tandem for this special dedicated exchange. The outlying CO's would then, if possible, be modified to give a regular 60 ipm busy for all trunks busy on this trunk group, as opposed to a standard 120 ipm (fast busy) or ATB recording. (This was a real hack job in some types of offices) The idea was to prevent the heavy peak from overloading the tandems and offices without sounding odd to the customers. By creating a bottleneck by limiting trunkage, the downtown tandem switch did not get buried (it was also modified to act the same way on calls originating within the downtown switch). The tariffs filed by telcos in most states allow numbers to be reassigned to customers at the telco's discretion. The telco went to all the stations and forced a number change and dedicated contest/request lines to be used by the stations. Stations not in the downtown exchanges were offered FX services. In some areas, these exchanges were consolidated accross area codes, such as L.A. In many areas special tarriffs were put into place to offer this high traffic response service at a special premium rate, because a large calling area was being delivered at local rates. This was done because 800 service could not be configured to deal with this problem at the time. With the new ESS machines in use, similar, but improved schemes are currently in use. This is complicated by the various types of older CO switches out there and uncooperative independant (non-Bell) telcos, often becouse they are not offered CICS channels by the Bell co. or their switch is too dumb. A recent problem occurred in Akron, Ohio not too long ago that justifies this design philosphy... Seems an older local station (WQMX 94.9) got bought, changed its format from elevator music to contempary rock and needed to build its listeners. Good old American marketing enters the picture...and the station widely advertises they are going to give away $10,000 to the 100th caller at 7:30 one designated morning. The number they advertise is a regular POTS number (with three line rotary hunt group). Now their broadcast coverage area includes Akron-Cleveland-Canton Ohio. Cleveland or Canton to Akron is an inter-LATA toll call. The effect of this promotion is: 1. Akron's University ESS switch (216-836,864,867,869,860) is brought to its knees. This is the switch that serves WQMX. It is completely no-tone for almost 20 minutes. 2. Several local tandems are thoroghly messed up. Akron's downtown Blackstone exchange ESS is overloaded for the first time in its history. Operation is erratic, at best. Many of the inter-LATA carriers use Blackstone as their closest Point of Presence to University central office. Blackstone's many Centrex customers are affected as well. 3. ATT, Sprint, MCI and others are overwhelmed by Cleveland to Akron calling. Also a record. 4. Somebody wins the money, eventually. 5. Nearly thirty minutes pass before the network recovers. Ohio Bell never knew what hit them. Statements in the newspaper to that effect the next day showed WQMX did not communicate its intentions to Ohio Bell and did not subscribe the tarriffed services for this use. WQMX widely advertised the promotion and it was noticed by some Ohio Bell personnel, but they did not think much of it at the time, and no prior arrangements were made. Needless to say, such facilites have been put into place recently. WQMX has been trying other stunts to attract listeners, but not this one again. And the public has its reassuring dial tone again. WQMX's latest stunt was a girl with a cellular phone standing in front of a billboard saying: I NEED A JOB! CALL ME: XXX-XXXX over a busy Akron freeway during morning rush hour. The idea was to get the girl, really a new morning jock just hired by the station, on other stations' live morning programs and then plug WQMX. This one gave the cellular co. some extra traffic, but did no harm, other than upset a couple of the other radio stations in the area. So much for telecom as a promotion tool... telemarketing anyone? FACT: Most central offices are engineered for around 10% maximum usage. That's right. 10% of you all, businesses and residences, get on the phone at once, in one CO, and look out. (This number varies with the type of switch and its engineering, but its a good, round number) This will also be declaimed by many Telcos, but thats the way it is.

You're thinking of WINB (World in Need of the Bible), which is owned by the same company (Red Lion Broadcasting) that owns WGCB. My home is less than a mile from their studios and transmitters. WINB is a shortwave broadcast station, their transmitters and studios are located in an old chicken coop! Almost everything in that station, and their sister stations (WGCB-AM,WGCB-FM and WGCB-TV 49) were build (and I talking transmitters, control boards, limiter circuitry) by one of the neighbors back home. The chief engineer at one time was another neighbor. Needless to say, when the younger members of this family-owned outlet took over, everything went to pot (so to speak). Incidentally GCB stands for God and Country Broadcasting. Last time I was home (my mother and brothers still live there), they were still up to their nefarious tricks, the most offensive being that they never kept on their assigned frequency. For example, I normally listen to WITF-FM in Harrisburg, which is the local Public Radio outlet, when I'm back there. It was not uncommon for WGCB-FM, which operates at 96.1mHz to bleed over on to WITF-FM's frequency, which is at 89.5 mHz. Repeated calls to management there, and to the FCC were NEVER to any avail. I won't go into the character of the current owners and their management, but maintainence on that station's equipment is next to non-existant (and this was told to me by the neighbor who used to be the chief engineer). Randy Miller rs.miller@pro-harvest obsolete!pro-harvest!rs.miller [Moderator's Note: I think WVOA is out of Bethel, NC. I never listen to them anymore -- haven't for years. KVOA is on the west coast.

Reference: |Digital Telephony|, John C. Bellamy, John Wiley & Sons, 1982, pp. 90-113. These compression techniques are used in digital telecommunications to try to squeeze reasonable sound quality ("toll quality") into 8-bits. u-Law (that's "mu-law", not "you-law") compression is defined by: ln( 1 + u*|x| ) F (x) = sgn(x) * ---------------- u ln( 1 + u ) where -1 <= x <= +1, and sgn(x) is the sign function. The compressed value is usually represented as an 8-bit signed magnitude number: one sign bit plus seven magnitude bits. In this scheme, the most positive number is 0111111, the most negative number is 11111111, 00000000 is a positive zero, and 1000000 is a negative zero. The u-Law expansion formula is: -1 1 |y| F (y) = sgn(y) * --- * [ ( 1 + u ) - 1 ] u u In modern telephony, a value of u=255 is used. The first digital telecommunication systems (the "D1" channel bank) used u=100, but with the introduction of the "D2" channel bank a value of u=255 was selected to simplify the conversion process. This value allows Fu(x) to be easily approximated by 15 linear segments. This feature is not so important these days since it's easy enough to build a conversion lookup table into ROM. Please see Bellamy for more information on the linear approximation technique and details on constructing ROM lookup tables. A-Law companding is also discussed there. u-Law is used primarily in the North American and Japanese telecommunications networks, while A-Law is used in Europe.

I am generally aware of the state of ISDN deployment in Asia, but I am often asked how that compares with the status of ISDN in the United States. Japan, for example, has had active Basic Rate Access (BRA) service [INS NET-64] available for over a year now. And although the requests for this service were lower than orginal forecasts, NTT has begun service of its Primary Rate Access (PRA) service [INS NET-1500] and is continuing to expand the service areas of BRA. My question is what is the status of ISDN deployment in the US? Is is past the field trial stage and generally available to commercial subscribers? or much more limited in geographic availability? Also, with SS7 not yet widely implemented combined with the fragmentation produced by a multitude of non-centrally administered RBOC's, does the user community prefer to 'roll there own' network (using fractional T-1 for example) instead of waiting for ISDN?

According to a recent story in the Belleville, IL , the city is being billed for phone calls to dial-a-porn services and from points as far flung as Florida and Texas. The monthly phone bill for the city of East St. Louis averages $5000, and over the past year it has included calls to nearly every state as well as to '900' area adult talk lines. City Treasurer Charlotte Moore said the number of questionable calls in each month's phone bill, which is usually two inches thick, shows the 'need for better policing of phones'. No kidding! The obtained copies of the phone bill for several months under the Freedom of Information Act, and set about reviewing the places and people called. For example, from March through May of this year, hundreds of dollars in calls were made from places in Texas, Florida and elsewhere, and charged to a Calling Card number assigned to the city. In one instance, a caller in northern Florida made a 288-minute call to Miami that cost East St. Louis $39.27. The called the Miami number, and reached a man named John, who refused to give his last name, and claimed he '...had never even heard of East St. Louis...' Calls from one certain number in Houston to places all over the United States accounted for more than $1000 in charges over several months. A man who answered the phone at the Houston number refused to give his name and refused to discuss the matter, or explain how his phone might have been used for the fraudulent calls. Prior to intervention by the newspaper, the city had done nothing. Apparently they were not even aware of the abuse. On notification, the local telco cancelled all outstanding PINS, and issued new ones. Meanwhile, the city of East St. Louis continues to plead poverty. They are barely able to meet payroll for city employees, and have skipped a couple of paydays at that. The city has an extremely poor tax base, and will likely file bankruptcy in the near future. Maybe the FBI can go see the joker in Houston and 'John' in Miami and convince them to start paying their own phone bills!

A CBS News producer -- apparently part of a crew headed south for hurricane coverage -- was a passenger aboard the aircraft and had a cellular phone with him. After the plane went off the runway, and while he was still waiting to be rescued, the producer placed a call to CBS news in downtown New York. On the second cut-in on the crash, Dan Rather provided a brief introduction as to what was known at that time. With a distant live video of the crash scene provided by a remote unit as the visual, Rather then proceeded to do a live interview with the producer aboard the crashed plane, in which the passenger described what had happened and what the current situation was. The quality of of the sound was marginal, but still understandable. One could hear lots of on-site background noise, including people shouting to each other. --Ernest ------------------------------ Date: Sun, 24 Sep 89 16:45:07 EDT From: "Ernest H.

News reports indicate that hundreds of thousands in the area are without power and that it will probably be days before full power is restored. The bank that I use has its central computer facility in the Charlotte area. Saturday morning -- one day after the storm hit the Charlotte area -- I was unable to get the local teller machine to do transactions which required access to the main data base. However, by Saturday evening, these transactions worked without any problems. I suspect the problems were caused by lack of power to the computer site earlier in the day. I don't know whether the bank was able to get emergency power or simply re-routed processing to some alternate site, though I should be able to find out later. On the other hand, I had no problems reaching a friend living in Charlotte when I tried to phone. The connection was excellent, though she reported all power for a wide area around where she lived was out and that many trees were down. Streets were still only marginally passable a day after the storm hit. -- Ernest My opinions are my own and probably not IBM-compatible.--ehr Ernest H.

The standardization of dial tone to a dual frequency of 350 Hz and 440 Hz with a transmission level of -13 dbm was first proposed by AT&T and developed into CCITT Document AP III-84. I don't know the exact date of this CCITT standard, and don't have a copy handy, but I believe it was around 1963. This standard applies only to North America, however. Many European and other countries use a single frequency, most commonly 425 Hz. In is important to understand that this dial tone is produced by LINEAR mixing of two sinusoidal tone sources of 350 Hz and 440 Hz, and is NOT one frequency modulated by the other, which was the method employed with many previous dial tone supplies. The reason for the linear mixing is to reduce harmonics which may fall into the DTMF frequency domain and interfere with the interpretation of the first DTMF digit. The previous dial tone supplies were extremely rich in harmonics. The previous North American dial tone "standard" was 600 Hz modulated by 120 Hz; I use the word "standard" loosely here since in practice there was quite a variation because there was no technical _reason_ why the tone had to be precise. In older electromechanical CO's dial tone could be produced by a variety of apparatus, including motor-driven tone alternators, motor-driven pole-changing interrupters, electromagnet-driven pole-changing interrupters (i.e.,vibrators), ferroresonant AC-line powered devices, and in later years solid-state devices of varying stability. Interestingly enough, with one exception, I have never seen nor even heard of a call progress tone generator which used vacuum tubes. Technology in this area went directly from the electromechanical to the solid-state. The one exception was the "no-such-number" tone generator, which used vacuum tubes and made its debut around 1940; it has been affectionately called the "crybaby tone". This call progress tone (for lack of a better term) began rapidly disappearing in the later 1950's with the rapid implementation of intercept recorders which replaced it. The no-such-number tone had pretty much disappeared in the Bell System by 1965. The last "holdout" I am aware of which used this tone was Rochester Telephone, in Rochester, NY, and quite to my surprise I heard this tone when I misdialed a toll call to the Rochester area about four years ago. I was so taken aback - not having heard this tone for probably 20 years - that I was almost motivated to fetch a tape recorder and record it for posterity. :-) <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: Gabe Wiener Subject: Telegraph History....Again! Reply-To: Gabe Wiener Organization: Columbia University Center for Telecommunications Research Date: Mon, 25 Sep 89 02:54:59 GMT With all this talk of Western Union history and whatnot, I thought that these little anecdote might be appropriate. When Thomas A. Edison was a teenager in the 1860's, he used to work in a telegraph office. At one point, he was assigned to work the graveyard shift. Now in those days, a telegraph operator would have to send a six over the line (represented at the time by the morse signal ......, although the MODERN morse signal is -....). Anyway, there was very little traffic over the circuits in those days was very light in the wee hours. Now it is a well known fact that Tom Edison liked to sleep during his work. However, he was often admonished for nodding off durning his operating hours when he failed to send the six. So he rigged a six notched gear to the movement of a nearby clock, and whenever the clock would reach the hour, the gear would promptly roll over the telegraph key sending the six, and permitting Edison to get a good night's sleep. One of the first telegraph services in the world opened in England in the early 19th century. It was based on an electric telegraph, not a magnetic one. It was called the Lawyer's Telegraph Service. It connected up the various attorney's firms through a central switchboard. The calling operator would signal the switchboard via handeles, spelling out the name of the party to be called. The operator would make the appropriate connections, and the two firms could communicate. Certain movements of the handles would cause a bell to ring at the exchange, signalling the operator to take down the connection. Gabe Wiener - Columbia Univ.

I thought perhaps > it was people calling me from a computer, but then I'd hear a modem tone, > wouldn't I? ... No, you would very probably not hear a modem tone, if a modem were dialing you. With most modems in use today, the _answering_ modem is responsible for sending the first tone, after it goes off-hook. The type of answer-tone transmitted identifies the protocol(s) that the answering modem is able to use. The originating modem "hears" the answer tone, chooses a protocol, and begins transmitting its carrier. The answering modem "hears" the originator's carrier, stops sending the answer-tone, and begins transmitting its carrier. If, on the other hand, the originating modem never "hears" an answer tone, it will never "know" that the call has been answered, and will simply disconnect after 30 seconds or a minute and report a "NO CARRIER" situation to its pilot. So, a local- or long-distance call with nothing but silence on the other end could very well be from a modem. There are a couple of relatively common ways that you can end up with numerous calls of this type: 1) Somebody at a specific computer site has misprogrammed one of their outdial modems... for example, transposing a digit in the phone-number used to contact one of their "neighbor" systems. If this has occurred, most of all of the calls you receive will be from the same exchange (either all local, or all long-distance), and there's a fairly good chance that they'll stop after a few weeks. The sysadmin of the offending system will (probably) notice that a large number of calls aren't getting through, will figure out the problem, and will correct his/her dialer-file. 2) The phone numbers for computer-hobbyist "bulletin board" systems tend to be passed around between personal-computer users. Bulletin-board systems tend to come and go fairly frequently... the survival time for a BBS tends to be measured in months. If the phone number for a BBS is circulated widely, then there may be literally thousands of people who have a copy of the number. If that BBS then goes out of service (for example, if its owner/sysop moves), then the phone number will often be given out to someone who is having phone service installed. Subsequently, the new "owner" of this number will receive many, MANY phone-calls from computer hobbyists who aren't aware that the BBS is out of service. I rather suspect that you're facing the second of these situations, since you seem to be receiving calls from both local and long-distance sources. The only really effective solution of which I'm aware is to ask the phone company to give you a different phone number. They'll probably charge you for the service-change, since they can legitimately argue that the problem is not _their_ fault.

The three stations I work with that have choke prefixes do not pay any mileage. One simply because the 575 is served out of AXminster, their local office. The other two had previously been served out of AXminster but moved about a half-mile over the line into ALpine. An appropriate tear here and an "offer" for some Pac*Bell editorializing there, and the charges magically vanished. I understand that another station in town, served out of 95 Almaden, has a bunch of 575 lines used for some promotion and they also do not pay any mileage. I'm not sure why (but there is someone on this system who *does* know--hint, hint.) Which reminds me of the stormy beginnings of the choke network in the SF Bay Area. (Oh no, here comes another story, Martha!) It was about 1966 and one of the rock 'n roll AM stations discovered contests (really give-aways). Technicians in the 95 Almaden office were noticing these instantaneous overloads of the trunks and the crossbar switching equipment. In 1966 it was ALL crossbar. It didn't take long to determine who was the culprit. Phone company people were faced with a problem. Obviously they couldn't design the network to handle that peak demand on an occasional basis, and yet they couldn't be faced with periodic shutdowns that also prevented emergency calls from being placed. One of the suggestions was to tell the radio station that they couldn't "abuse their telephone service" in that manner any longer upon pain of disconnection. The radio station couldn't see the problem. "We only have four lines for the contest. How can we possibly be causing any trouble?" Of course, they had no idea of the trouble caused when hundreds of calls were directed at one number. Trunks would become jammed with busy signals (or reorders when the busy tone trunks would fill up) and normal calls would be blocked. Looking at the problem, they decided upon creating a special exchange that would have limited trunking and not share trunks with any other prefix. That way, the special exchange could busy out without affecting any other service. Hence was born the choke network. But this is not the end of the story. In 1972, some DJ at the big 50,000 watt rocker "discovered" how the choke network worked. He was furious to find out that callers could actually be blocked from calling him. He created a major stink which spread to other radio stations and ended up with representatives from Pacific Telephone and all the area stations in a conference. The long and the short of it was that PacTel insisted that it had created the choke network as a "service" to the stations, explaining that the only alternative was "contest prohibition". They made their point, the DJ was put in his place, and as an offering of good will, the area engineers were treated to a grand tour of 95 Almaden, the downtown office. (For you locals, the DJ was Tom Campbell, who hosted "KLOK Talk", where this issue came up.) Even so, from time to time, some DJ suddenly discovers that when he dials the request lines from an office extension, it's busy (reorder) and no request lines are in use. I have a canned explantion that usually calms him/her down. John Higdon | P. O.

Because the old 5-level Baudot machines were notorious for mechanical difficulties, there was an end-of-line sequence that became nearly universal. It was CR-CR-LF-LTRS-SPACE. It got to the point where I could practically type that as one fluid movement, and later I programmed it into some communications software that had to talk to the beasts. The reasoning was: Two CRs to make SURE that the carriage returned, since lots of the old machines would simply pile up letters on the right margin if it missed one - and that would mean that you'd miss a whole LINE of text. Also, if the carriage bar (the rod that the carriage slid on) had gotten dirty or the oil had gotten gummy (as it did every few months), the carriage would return very slowly which could lead to the next few characters printing backwards across the page. LF to advance the paper. It would have been more dependable to send two of these but we didn't want to waste paper. LTRS to make sure the machine was back in letters mode, and also to give the carriage just a little bit longer to get all the way to the left side of the paper. SPACE because the repair technicians didn't alway get the left travel stop adjusted properly and the first two letters on the left often piled up on top of each other, especially if the rubber bumper had swollen with age - or absorbed oil. - Brian ------------------------------ Date: Mon, 25 Sep 89 9:33:10 EDT From: Carl Moore (VLD/VMB) Subject: Prior Use of Fake Area Code 311 I have seen the fake area code 311, but I believe I saw 904 in use for DDD instructions in the microfilmed 1960 Wilmington (Delaware) directory. 904 was not in use yet; it came in in 1965 in Florida by splitting 305. ------------------------------ Subject: Re: Why Some Companies Won't Export Date: Mon, 25 Sep 89 11:55:56 PDT From: Brian Litzinger One of the problems with exporting products is that you generally must meet all the regulatory requirements of the nation that you are exporting to.

If you have two TE's on a single S/T bus (point to multipoint operation) there are two addressing schems that come into play. At the physical level, the S/T bus has a collision handling mechanism that restricts access to the bus to only one TE at a time. The NT (or switch) assigns a TEI (Terminal Endpoint Identifier) to each terminal device on the bus. TEI's can either be manually assigned by the service technician (dip switches etc) or can be assigned dynamically by management procedure software resident on the switch. Since the switch is aware of which TE is negotiating for a call it can assign one B-Channel to each TE device. In fact, in a multi-mode terminal, several calls can be active/suspended at one time, with each call having a distinct Layer 3 call reference value.

I once spent a miserable two days looking for an apartment in the west/ southwest LA area (almost all covered by GTE), driving around with a car full of newspapers and a pocketful of dimes. It got so I wouldn't even bother stopping at a GTE pay phone unless there were at least two of them together, as only then was it likely that I'd find a single working phone. The defective phones were in nice areas and had no signs of exterior damage -- they just didn't work. Often they'd be sitting there emitting strange clicking and thunking noises, as if they couldn't quite digest that last coin. Others would appear to be fine until you put a dime in. About three out of four of these would deign to provide a dial tone. About three out of four of THOSE would actually give a ringback signal after you'd dialed your number... (yes, GTE was charging 20 cents, on average, for pay phone calls LONG before it was authorized by the PUC!) I know a fair number of people for whom Pacific Telephone vs. GTE was a factor in choosing a place to live -- and not the least important factor by far. Oh, and then there was the "GTE Phone Center" in Del Amo mall, which opened at 9 AM and closed promptly at 6 PM on weekdays, and was not open at all on weekends. I had to visit this place at least twice to establish phone service. I got off work at 5 PM, at (roughly) Wilshire and Crenshaw. This is a thirty-minute drive under the best of conditions (say, at 2 AM). Good luck! Apparently these people had never heard of households where both people work, nor of making their company easy to do business with. > The apparatus will indeed do the job - but in the situations which > you describe it is PEOPLE who have let the apparatus down and caused these > service problems. So what? When I say that "GTE gives lousy phone service in the LA area", I am not complaining about the equipment, the wiring, the management, or the color of their trucks. I'm complaining about the whole picture. I don't know what the underlying reason is, and for the most part, I DON'T CARE! I just want things to improve! > Now, the burning question is how could GTE allow this to happen in > California?

The GTE logo is prominent on many products sold in the commercial and consumer sectors. The Los Angeles area is not exactly devoid of customers for such products. My experiences with GTE phone service would definitely make me wary of anything else with the GTE logo. Yes, I know, different parts of the company... but if they don't care about QC in one division, why should I believe that others are any different? --- Jamie Hanrahan ------------------------------ Date: Mon, 25 Sep 89 19:52:57 edt From: Thomas Lapp Subject: Re: How Hugo Affected Telecom Service Reply-To: mvac23!thomas@udel.edu Martin B Weiss writes: > My parents live on the SW corner of Puerto Rico.

Sorry Dave, but OTC changed ISD to IDD (International Direct Dialing) a couple of years ago. They also just dropped the rates - we can now ring the USA for A$1.19 off peak [how does this compare with US to Aust costs?]. We are not charged extra for touch tone lines - if you are on an AXE exchange you can use DTMF, if not, you can't. When I purchased a house that had never had a phone I enquired about getting a DTMF line and was told that because of the demand for lines on the AXE exchange (one out of six prefixes serving my area is AXE) that the only way to get a line on it was to sign up for Easycall (rather like StarNine). Telecom Australia charged me the following: Connection Fee A$225.00 (no existing line or handset) Exchange line A$ 11.65/month Easycall Services (1st 3) A$ 4.25/month Additional Easycall services A$ .53/month each With regard to area code splitting, I came across an interesting example in the Canberra telephone directory. Formerly, Canberra, Yass & Queanbeyan in the Australian Capital Territiory (ACT) used to have an area code of 062. Now Yass has been split off from Canberra with an area code of 06 and by prefixing all numbers in that area with a 2. What this gains, I have no idea. 062, 063, 064, 065, 066, 067, 068, 069 & 060 are all in use and no normal phone #'s start with 1. In an article from Australia (which has expired here) someone asked about data corruption which started 15 minutes into his call if he left his phone in parallel with the modem. I sent him a copy of the discussion which covered this topic in Australia earlier this year. For your interest, the problem is that Telecom Australia now supply push button phones with memories as standard equipment on new lines. These phones need about 9 volts across tip & ring to keep the memory intact. Most modems I have come across have an impedance low enough to pull this voltage down to 1 or 2 volts. After 15 minutes, the phone tries to recharge its memories and corrupts the data. The solution is either to unplug the phone first, or obtain a current sharing module to ensure that the voltage at the phone does not fall to low.

Late 1970's through early 1980's Plantronics Inc. in Santa Cruz, CA built and marketed a system called CentraVox--a CO based answering machine for individual subscribers. FCC ruling against recording devices in COs finally killed the product line. Last op rating system that I am aware of was part of the PNB system in the Seattle area. The service was popular among the masses, I am told. Consisted of a 19" rack mounted aluminum box with p/s and central tape driving motors. 12 individual line modules would independently push tape and a rubber roller against a rotating shaft to drive the tape. Two tapes, an announcement on a loop and about 20 minutes message tape included in an interchangable unit about the size of a cassette recorders All of the electronics other than the voice recording was digital. The system was controlled by DTMF signals from the subscriber and there was a tone sequence indicating waiting messages when the handset was taken off hook. VOX was the other feature, up to a 20-min length of message was possible, and th system sensed the end of "intelligibility" and then rewound the tape to that point to await the next call. All features for control were available from the unmodified home telephone and there was a remote included so that you could access your service by using your home number remotely and sending a BCD signal to authorize. You could change announcements, listen to and erase messages all from any telephone. Cost was very low to the consumer as well... Too bad it died just in 1984!

PT] This service, which must be pretty rare by now, was referred to as "Toll Subscriber Line Service". The tie lines were ground-start trunks at the PBX end (for either manual and/or dial level access), and terminated in special toll subscriber trunks at a No. 1 or No. 3 Toll Board, or in later years at a TSPS installation. Since these toll subscriber trunks served specific locations, the toll operator obviously knew where the call had originated. Prior to TSPS, the originator of the call never dialed any digits; they gave the desired number to the operator along with their room or extension number, and the call was completed by the operator in a manner no different than dialing "0". Once per hour, toll tickets from toll subscriber customers would be collected from toll board operators, the call rated, and charges transmitted to the subscriber PBX via a teletype or by having an operator call the PBX attendant. Teletypes were simply a point-to-point manual link, and were only used in higher traffic installations. The PBX subscriber paid an additional rate for this service. As TSPS became more common, toll subscriber line service permitted the originator of the call to dial the desired number into a toll trunk and register, with the TSPS operator coming on the line only to ask for room or extension number. It was not possible to eliminate the operator since there was no ANI from the PBX to indicate the room or extension identity. In the late 1970's the Bell System offered a totally automatic toll subscriber service called HOBIS (Hotel Billing Information System) which required no TSPS operator intervention. HOBIS automatically transmitted calling data to a teletype as it occurred. HOBIS did require the subscriber PBX to have ANI or SMDR capability; I don't know the exact details, however. Most of the toll subscriber line customers were hotels, with the rest being universities, hospitals and similar facilities. With the extensive use of electronic PABX's having SMDR and call-costing capability, toll subscriber lines are pretty much a thing of the past as hotels and other subscribers are quite capable of determining toll charges on their own. Also, the advent of divestiture, ALDS and AOS has totally changed the picture; since the philosophy behind HOBIS does not exactly fit in this picture, HOBIS may well be dead. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" [Moderator's Note: Well, that was a heavy traffic location. We had about 4000 campus extensions; three separate groups of incoming CO trunks (MIdway-3-0800, MUseum 4-6100, NOrmal 7-4700, with about 250 incoming CO trunks between them. The 'Midway board' served the main campus with about 2500 extensions spaced over nine positions; the 'Museum board' had about 1000-1200 extensions and served the Medical Center on six positions; and the 'Normal board' had a mere three positions serving maybe 500 phones at the Enrico Fermi Labs and the Computation Center. All sixteen or eighteen positions (I forget exactly) had tie-trunks to each other, of course, so that a caller in the 8000 series of extensions (Fermi) reached the 2000 series of extensions (main campus) by going off hook and asking for the desired extension. The operator who took the call would select a tie-trunk to a position on the other side of the room. When that operator came on, she did not speak: you knew she was there because you heard a 'click' in your ear, and you would repeat "2374", or whatever your caller had told you. As fast as you could say the 'two three' part of it, she already had the cord up to that strip. When you got the 'seven four' part out, she was testing for busy with the jack. If she heard a click, the line was busy and she would so quote; otherwise she shoved in the jack and was ringing it. I dare say manual service with *trained* operators was just as fast as dial service; maybe faster sometimes. By around 1962 the extensions at least could dial each other and outside local calls even though the operators still took incoming and long distance stuff.

This brings up a question that I've had for some time. Is there a telephone set on the market with editing capability? What I'd like most is a backspace key. Especially, now, when a telephone number can contain ten or more digits, it is extremely frustrating to hit an incorrect final digit. The case sighted above would be considerably more frustrating. It seems to me that the technology should be relatively simple. To use the facility, the numbers would have to be buffered, and sent when some sort of carriage-return or enter key is hit. So there could be a switch for buffered or unbuffered input. And, a display of some sort (LED?), that displayed the digits in the buffer, would be nice. Does anything like that exist? And if so, how much does it cost? (Oh...I have only pulse-dialing where I live. I'd want that feature on the phone as well.) -- Charlie Goldensher charlie@vicorp.uu.NET [Moderator's Note: Aren't cellular phones sort of like this? You punch in the entire number, then 'send' it.

This appendix lists 12 different 5-level codes as well as 2 6-level codes and the "standard" 7-level code. The order seems to differ from what you list (but that's probably because the bits are backwards :-). It also points out that BEL wasn't always FIGS-J, there were also codes where it was FIGS-S. I'll bet this was a barrel of laughs if you hooked up a machine with the wrong code! In addition, for those discussing transmission rates, Appendix E of that same book lists many speed/format combinations and what use they were put to.

The phone was marked that 0+ and 1+ calls other than those authorized to be carried by C&P, would be carried by (in capital, red letters) AT&T COMMUNICATIONS. 1 700 555-4141 "You have reached the AT&T Long Distance Network" 10 222 1 700 555-4141 "You have reached the AT&T Long Distance Network" 10 333 1 700 555-4141 "You have reached the AT&T Long Distance Network" So, all 1+ calls are routed to AT&T for coin collection (although this call, being free, requested no money). 10 XXX codes are ignored for 1+. Then, the following were tried: dialed: 0 + valid out-of-LATA 10-digit number response: "bwongg (without the 'AT&T')" dialed: my valid 14-digit Bell Atlantic/AT&T card number response: "thank you for using AT&T" and call rings through dialed: 10 222 0 + valid out-of-LATA 10-digit number response: "bwongg" (without the 'AT&T')" dialed: my valid 14-digit Bell Atlantic/AT&T card number response: "thank you for using MCI" and call rings through dialed: 10 333 0 + valid out-of-LATA 10-digit number response: "bwongg (without the 'AT&T')" dialed: my valid 14-digit Bell Atlantic/AT&T card number response: thank you for using US Sprint" and call rings through dialed: 10 488 0 + valid out-of-LATA 10-digit number response: "at the tone, please dial your card number or dial zero for the ITI Operator" (pause) "beep (like an answering machine)" dialed: my valid Bell Atlantic/AT&T card number response (after about 10 seconds): "please wait for card verification" (incredibly long pause, about 30 seconds of dead silence) "thank you for using ITI; if the party you are calling is busy or does not answer, press 1 to leave up to a one minute message" call rings through So there is true equal access, using a Bell card number, for 0+ calls out of LATA. Long distance carriers like ITT (whose 10 XXX is 488, above), who do not offer their own operator service route your calls to an AOS, which I believe ITI is, for billing. Some AOS's, like ITI, offer value-added services as well, as above. Did the difference between the way the MCI/Sprint calls were handled and the way the ITT call was handled mean that Bell Atlantic (C&P) was providing the card verification for MCI and Sprint but not for ITT?

When I visited New Zealand, I found that their radio stations also use call signs of one digit and some letters, the digit denoting which part of the country the station is in. Christchurch area stations began with 3, for example; I remember 3BZ. (Z pronounced zed, of course.) The person who pointed this out to me, however, also said that the *official* call letters of each station included a prefix which was the ITU code for New Zealand. I think that that was NZ -- some of them do have mnemonic value! -- so that 3BZ was really NZ3BZ but mostly did not mention that. So perhaps Australians do the same thing. It is not unknown for individual stations here in North America to adopt this approach; in Toronto, CKEY on 590 kHz is "KEY 590" in all its advertisements nowadays, and in Buffalo, WGR on 550 kHz is "GR 55" in theirs. There must be many other examples. (Hint: too many for it to be interesting for everyone to see the ones in YOUR hometown.)

On a basic rate interface (2B+D), the terminal equipment share the D channel. Call setup/teardown messages (Q.931) are message packets, each containing a Terminal Equipment Identifier (TEI). The TEI tells the switch which terminal on the BRI is requesting a service, and allows the switch to individually address each piece of terminal equipment. Not only is it possible to have both bearer (B) channels in use simultaneously, you can also use the D channel for data communication, all at the same time (e.g., a pc with an ISDN terminal adapter that contains an X.25 PAD). There's a clever mechanism for preventing signaling packet collisions using the echo D channel, but that's beyond the scope of your query.

Separate telephone companies have been set up for phone system in Delhi and Bombay. They are called MTNL - stands for Mahanagar Telephone Nigam Ltd. There are plans to set up MTNLs for other big cities as well. (Mahanagar is metropolitan area, Nigam is corporation.) Of course, VSN and MTNLs are government undertakings, but they have much more autonomy. There has been further liberalization. Private sector companies have now been allowed to make PABX, RABX (Rural Auto. Branch Exchange) and consumer items like telephones, answering machines etc. The customers now can hook up their own instruments. >Ah, the telephone service!

In the summer >after almost every rainstorm thousands (I'm not exaggerating!) would >be knocked out. Now, the waiting list is more like 5 years, and the goal is to provide telephone on demand by 1995 (approx.). All the exchanges that have been installed in the last 3-4 years are digital. In fact, all exchanges that have been installed in the last year have custom calling features like call-waiting and detailed billing for your STD and ISD calls. You even get the recording from these places like "The number you have dialed is not in service" in 2 languages. (3 languages in many places outside Delhi.) There are much less problems in rainy season. They have replaced old cables by pressurized cables, which are more resistant to water-seepage, in congested areas. And yes, they have laid pipes to carry these cables, so that they don't have to dig up the road if there is a problem with the cables. The customer service is much better. The best part is that you no longer have to pay by cash or cashier's check. You can pay by personal check. You can still not mail them, but you can deposit them in almost any bank or post office. Last year the yellow pages were published for the first time in India. All this in just about 3-4 years.

Concessional half the ordinary. 2. Ordinary 3. Urgent twice the ordinary 4. Lightening 8 times the ordinary Concessional calls are really the ordinary calls that start between 10pm and 5 am (and all day Sunday, 26th Jan, 15th Aug, 2nd Oct). All operator assisted calls are measured in the units of 3 minutes. Within each rate, one has an option of person-to-person call, but if the person is not present at the other end (but somebody did pick up the phone), some small charge is made. This is to discourage use of coded messages as name of person. The most convenient way of calling is the "Fixed-Time" call. You can book a fixed time call in at least 2 hours in advance. The operator will call you at that time, and will try to connect you with the other number. You pay the "Urgent" rate, but somehow the call always goes through, while the other urgent calls (which are supposed to go through as soon as there is no lightening call) may have to wait. There is slight penalty though. You can cancel a booking until the call goes through, but not with fixed-time calls. You are charged for a minimum of 3 minutes. There is no collect calling or third-party charge. The ordinary tariffs are: (rather were, for they are 2 year old, and were revised upwards last year.) Distance (in KM) Tariff for 3 minutes. (In Rs.) up to 20 1 21-50 2 51-100 4 101-200 8 201-500 12 501-1000 20 1001 and above 24 (1 Rupee is 6 cents) I don't know the rates for operator-assisted international calls. For direct dialed calls (STD and ISD), the tariff is determined by the "pulse rate." For every "pulse", you are charged equivalent of one local call, which was 50 paise (3 cents). For STD, the pulse rate is halved during night time. (I am not too sure about this.) But there is no discount for ISD calls in the night. For STD calls the pulse frequency varies from 30 seconds (upto 20KM) to approx. 2.5 second (1001 KM and above). I don't have the detailed rates. For ISD, the things are much simpler. There are only three pulse rates. 2 sec. for Nepal, Pakistan, Sri-Lanka, Bangladesh and Maldives. 1.2 sec. for the rest of Asia, Africa, Australia, most of Europe. 1 sec. North and South America, and some countries in Europe. e.g. A one minute call to USA would cost 60 * .50 = 30 rupees (1.80$) Almost all the countries can be dialed direct, including USSR. On a quick glance, the countries that I found missing are: China, Burma, Vietnam, Combodia, North Korea, South Africa. (This list is 1 year old, and since then we might have established direct-dialing with China.) There are other tariffs. There is a 100 Rs. testing fee for private equipment. There is a 200 Rs. yearly charge for each facility on the phone (like memory dialing, push-button dialing, STD barring). There is 300 Rs. yearly charge for phones with auto-dialer facility. There is a one-time charge of Rs. 1000 for installation. There is no unlimited service for local calls. How can it be. The STD calls and ISD calls are also counted as number of local calls. The telephone "rental" is 200 Rs. for two months (The billing is bi-monthly) and you get 300 free local call. (I am not very sure about the local calling rate.) Additional local calls are 50 paise each. Calling cards (more like debit card) were introduced last year in areas served by the two MTNLs. You can buy a card for various denominations. You can use them in special phones that will accept them. These phones are located mostly near places like Airport, Railway Stations, Hospitals, and places of tourist attraction. The cost of the call is deducted and the remainder is written back on the card. By the way, there are three kinds of public telephone booths. One, from where you can only make local calls. They will only accept 2 fifty paise coins, and not 1 one rupee coin or other change. Second type is from where you can only make STD and ISD calls. These will accept only those 1 rupee coins that were made after 1980. (But that is no problem, since usually a group of these types will be manned by one guy, whose only job is to give you the correct 1-rupee coins for your bills, or older 1-rupee coins.) The third type are the ones that accept card, and are found only in Delhi and Bombay. There is no surcharge for using the public phones to make long distance calls, but local call is costlier. It is 1.00 Rupee. -dheeraj Dheeraj Sanghi (h):301-345-6024 (o):301-454-1516 Internet: dheeraj@cs.umd.edu UUCP: uunet!mimsy!dheeraj Marriage is the sole cause of divorce. ------------------------------ Subject: CO voice mail Date: Mon, 25 Sep 89 1:10:33 CDT From: "David W.

One type is handled like a credit card of the telephone company: for using it you make an operator assisted call and tell the operator your card number, or you type the card number directly into the phone (e.g. USA). For the other type you pay a certain amount and this amount is coded on the card itself. For usage you push the card into a special slot of a public phone, and the coded amount is decreased while making a call. An "empty" card can be thrown away (e.g. Switzerland). What I would like to know: Isn't there a country (or LDC in the US) where phone calls can be paid be regular, internationally accepted credit cards (Visa, Master Card, American Express, etc.)? Phone calls would get much easier while travelling abroad. Or is there a reason, why telephone companies do not accept them?

Make them HEAVIER, and put a nonskid base on them. As I write this, I have just pulled my ATT-issue (came with System 8.5) sculpture off the desk for the umpteenth time. Guess I'll end up taping it to the desk, like many do around here. 2. Shape the handsets to FIT THE HUMAN HEAD! Real people do not talk daintily holding the handset in their fingertips. They jam it on one shoulder so they write. This worthless thing promptly shoots out of sight if you try. 3. Don't position the cord connectors so the handset cord tangles unto itself 2 inches from the base. (see # 1, above). Put the line cord where the it won't cause the phone to trip over it whenever you move it six inches. 4. Put a button for each function! (ie, hold, transfer etc). Phones should not require constant referral to the manual to operate; they should be self-evident. While you're at it, make the buttons REAL, with a click. A pox on squishy membrane switches and finger-nail-tip size buttons a quarter inch apart. 5. Make cords that don't lose their coil in a month, or that act like a DNA molecule and coil back on themselves, with a non-porous surface that doesn't get filthy immediately . (That also applies to the whole phone. Make it cleanable!) 6. Make a ringer/bell that can be tracked by ear. In an office full of chirping crickets, all with the speakers buried, it is often hard to tell which one is ringing. I could go on for another page, but you get the idea. Fancy sculptures may sell well in the catalog or showroom, but are often miserable for the users. (This translates to Lo$t productivity.) Buyers: Get a thirty-day 'test-drive' clause. Designers: (including ATT, WECO, etc): Go back and look at the 500 and 2500 series desk sets again. There is a reason they lasted so long, and were so widely imitated. They WORKED!!!

The marketer had figured that dealing with someone who had difficulty speaking gave him or her the right to claim a fake sale. I called the Illinois Bell business office for them and complained. I told them that my parents are perfectly willing to dial by pulse and that they can switch their telephones over to tone after reaching the other end when they call something that requires audio response. The representative tried to convince me that oh no, they can't do that without paying for tone dialing! If you don't pay for tone dialing, your telephones cannot generate tones! I demanded to speak to her supervisor and started over, asking for the bill to be adjusted (it was, but how many people would have paid without looking the bill over?) and for her to straighten out the representative about audio response.

Actually, it goes like this: ZL1xx = northern North Island, essentially Auckland ZL2xx = southern North Island, essentially Wellington ZL3xx = northern South Island, essentially Christchurch ZL4xx = southern South Island, essentially Dunedin It is true that the stations *never* announce the "ZL". One reason for this is a sentimental attachment of many New Zealanders for Mother England, whose stations' call signs really do start with numbers. Thus the Auckland station ZL1YA sounds British and serious when it calls itself "1YA". Newer FM and rock stations, of course, since they appeal to a younger audience who couldn't care less about Mother England, are discarding the number as well: ZL1ZM-FM, for example, just calls itself "ZM-FM", and the Auckland University campus station, ZL1BFM (I think), never identifies itself as anything other than "Bifim". ### T.

With the Australian dollar currently selling for A$1.26 to US$1, your rate is equivalent to 94 cents per minute. AT&T's economy rate is high ($2.16) for the first minute, and then .81 per minute after that. Thus a call of 13 minutes or less is cheaper if originated at the Australian end. Using Sprint, at $1.84/.78 the crossover occurs after six minutes. AT&T hasn't lowered rates to the Pacific for a long time; I think a lowering of at least the initial minute is long overdue.

My experiment will be a little cheaper than Greg's, because I keyed in my AMEX card number (no pin).

Not an issue. No different from setting up a voice call on the B1 channel and a data call on the B2 channel with today's sets. (my experience being limited to the AT&T 7506 set). During a "call", the D channel is in no way "dedicated" or tied to it. Q.931 provides bit fields to support connections to several entities simultaneously. In fact, while handling the above scenario I suspect you could also sustain an X.25 data link over the D channel, be reporting gas meter usage, etc. all at once. chris ------------------------------ From: goldstein@delni.enet.dec.com Subject: Re: ISDN Subscriber Equipment Date: 25 Sep 89 21:55:28 GMT Organization: Digital Equipment Corporation, Littleton MA USA In article , fff@mplex.UUCP (Fred Fierling) writes... >>From what I've read I understand that the U interface would be provided >via an single pair coming from the CO to the subscriber's premises and >terminate on an NT1 box which would provide the S/T interface to all >digital telephones on the premises. >Assuming this is correct, I understand that it would be possible for two >independent calls to be handled on each of the B channels.

Each terminal has a unique address (TEI) so the network knows which one is which; there's a procedure for auto-assigning TEIs, or they can be manually set.

Hayes-compatible modems let you do this by adding a semicolon to the regular dial command (e.g. "ATDT5551212;").

You know-those > dee-doo-DOO, "The number you have reached..." What are the frequencies > to them. Ive NEVER been able to find out what those are. These tones are called SIT (Special Information Tones). Their purpose is to permit an automatic Call Disposition Analyzer (CDA) to differentiate between a human voice and a recorded announcement, and to categorize the type of recorded announcement. A Call Disposition Analyzer is an automatic device, today totally computer-controlled, which automatically dials test calls over certain test subscriber lines, tandem trunks and intertoll trunks for the purpose of evaluating the connectivity and grade of service of all or a portion of the DDD network. A CDA may access a local subscriber line and outpulse using DP or DTMF, or in the case of tandem or intertoll trunks outpulse using MF. A CDA may be programmed to dial a milliwatt test line (102-type from tandem or intertoll) or a transmission/noise measurement ATMS responder test line (105-type from tandem or intertoll). The results of test calls are logged and categorized. The SIT tones facilitate categorizing a call failure which results in a recording. I don't know the SIT frequencies, either, except that they are not far from 600 Hz. The two CDA's which I have seen (Northeast Electronics and WECO) did not in fact have any frequency discrimination circuitry; they merely looked for three sequential tones occurring in less than 3 seconds using a bandpass filter centered around 600 Hz. Actually, I believe that AT&T had some more grandiose plans for the SIT tones which in fact were not implemented. Last I knew - which is actually some years ago - the same department at AT&T which assigned the verbal tandem and intertoll announcement failure codes for recordings said stay tuned for SIT assignments. I stayed tuned for a while, but never heard anything. :-) <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Tue, 26 Sep 89 08:54:45 EDT From: Bernard Mckeever Subject: Digital Channel Banks Reply-To: bmk@cbnews.ATT.COM (bernard.mckeever,54236,mv,3b045,508 960 6289) Organization: AT&T Bell Laboratories Here's a subject I haven't seen here before. I'll start it off and hope that [insert your name here] has the time to provide us with another of his informative articles. BTW, The traffic on this group is picking up and I notice that MANY of the readers have extensive knowledge of the "early days". Keep up the good work! Please feel free to correct any mistakes in the following. ========================================== The first commercially available digital channel bank for use by the telephone company was introduced in the early 60's and went by the name of the D1 channel bank, also known, at that time, as T1 carrier. Some time latter T1 carrier would be used to describe only the interoffice facility used for transport, and D1 would refer to the D1-A bank. The system used Pulse Code Modulation [PCM] and channels shared the facility by means of Time Division Multiplexing [TDM]. Each channel bank could provide 24 time slots [channels] and the the channel units and related common equipment were called a digroup. The banks function was to convert voice frequency and channel signaling information into a string of 1's and 0's and take this same string at the far end and turn it back into its' original form. As someone mentioned D1-A [D1-B] used A-law encoding a 100 step linear encoding scheme to "digitize the voice signal. Signals were first sampled and converted to a Pulse Amplitude Modulated [PAM] signal and passed to the COder/DECoder [CODEC] for conversion to 7 bit digital codes, an additional signaling bit was added to each byte to form an 8 bit byte. Each channel was sampled 8,000 times per second and at the end of 24 bytes, a framing bit was added. This gave us a multiplexed line rate of 1.544,000 bits per second. Also as mentioned D2 used u-255 [Mu-255] a non linear encoding scheme that used 8 bit voice encoding in 5 of 6 frames and 7 bit encoding every 6th frame. In every 6th frame a signaling bit was added to each byte. The frames were now aligned into a 12 frame Super Frame [SF], during frame 6 signaling information was sent on the "A highway" and in frame 12 on the "B highway". This required the frame bit to "share" information so the terminal and the signaling equipment knew when thing were in sync. D2 banks did not last long but were the 1st Toll grade digital terminals. Next in the series was D3 terminal banks. About 1/2 the size of a D1 bank D3 used the same line coding [SF] as D2 and provided additional Special Service Applications. Each system mentioned used the same line rate [1.544.000 b/s] but were not end to end compatible. Each used a different channel counting sequence. In theory you could connect D2 and D3 but why bother, most of the systems by that time were either D1-B or D3. D1-B was not compatible with D2 or D3 because of the different encoding schemes. Next came D1-D a major retrofit to D1-B that used the same encoding and framing scheme as D3. This allowed the VERY large base of older D banks to be upgraded to Toll grade service and to provide additional special service applications. One of the first uses of D1-D to D3 caused some embarrassment to the testers who turned up the system. They said everything is OK and the Circuit Provisioning Center [CPC] started to assign service. The 1st circuit turned up without a problem but they could not tone out channel 2 for the second circuit. After hours of head scratching someone [me] remembered that D1 banks count channels 1, 13, 2, 14,....12, 24, and that D3 counted 1, 2, 3,....23, 24. when the system was accepted they only toned out channels 1 and 24, quite a common practice. They forgot to install the adapter at the D3 end of the span because at that time they did not know a D1 would be at the other end. After D3 came D4 [what else] a 2 digroup system [48 channels] that could operate at several line rates DS-1 DS-1C DS2 and provided twice as much service in the same amount of space as a D3 bank. Today, by far, D4 banks are the dominant system in North America. D4 also is the basis for SLC-96 carrier systems. Many other digital terminals still exist in the network and a new generation of them are starting to take over where remote operating centers are in place. ------------------------------ Subject: Tone Plant & Stromberg-Carlson Date: 26 Sep 89 23:33:02 EDT (Tue) From: Larry Lippman In article john@zygot.ati.com (John Higdon) writes: > The dial and busy/reorder tones in a stock Stromberg XY are generated > by a device which uses a single vacuum tube.

Anything is possible with Stromberg-Carlson, I suppose. I have not seen any S-C tone generators which used vacuum tubes, however. All of the S-C F40 and F80 XY PABX's used ferroresonant tone and ringing generators, which I believe were made by Warren. In the case of S-C XY CO's that I have seen, while the office interrupter panel was always S-C, the tone plant was usually Warren and solid-state (Warren had solid-state tone plant in the 1950's). I have also seen Lorain solid-state tone plant in XY CO's, along with some older Holzer-Cabot ringing-tone machines. No vacuum tubes, though. Now, in my humble opinion, if there is an apparatus manufacturer worthy of bashing, it is Stromberg-Carlson. XY worked well until the first careless switchman or screwed-up selector or connector banged into the wire bank multiple. No matter how one tried, one could NEVER get a banged wire multiple straight enough so that it again worked reliably. As far as I am concerned, XY ran on a wing and a prayer, and was pure junk. S-C was notorious for test apparatus that was built into cheap flakeboard cases, painted a mottled maroon. Even when S-C came out with their electronic Cross-Reed systems (which were awful), the test sets were STILL built in a junky case which flaked wood and paint just by looking at it. It's hard to get a feeling of quality when your $ 1,000,000 ESS switch comes with test sets which look like painted orange crates. > Although rapidly disappearing, the California desert is peppered with > exchanges using the XY.

I don't believe that true telegrams exist in the U.S. anymore, meaning written communications handled on both ends by Western Union, but 'telegrams' still have a special place in U.S. legal usage. Twice, I have sold houses when I was out of town when I accepted the offer. In each case, the real-estate agent instructed me to send a telegram indicating acceptance. In both cases, I actually called the telegram in to the 800 number; in the most recent case, the telegram was actually delivered by mail, WU no longer having any messengers in this area (Boston). I've never checked this usage with a lawyer; it could be that the real-estate agents were just using old practices. But some of them hadn't been in the business long enough to be familiar with real telegrams.

In the mid-fifties when television was in it's infancy, one of local stations teamed with a super market chain to produce an audience participation version of Bingo. The playing slips were passed out at the super market during the week. Then on Saturday evening at 6 or 7 pm the station had a 'LIVE' show during which the numbers were picked with the usual column of air blowing numbered ping-pong balls from the bin. Innocently, the TV station advertised it's own telephone number. "Gee, with a ten line PBX, we can handle the calls." No way! When the game progressed to the point that boards were nearly complete, the calls started to come in and all the telephones in downtown Denver quit working. On Monday, the Engineering staff was put to work to find a way that this wouldn't happen again. The TV station and the super-market had spent a lot of money promoting the game so they were 'extremely' reluctant to postpone future shows just because of an inconvenience to the Phone Company. Obviously the solution required additional equipment but where could they find the equivalent of another Central Office in less than than a week? Then someone eyed the companies own PBX. It was the equivalent of a central office and virtually unused at that time of the week. During normal working hours some twenty operators were employed answering incoming calls. All the requests for service, personal calls to employees as well as the many business calls were handled through the one rotary number ( TAbor 5-4171 ). But on Saturday night, only two ladies were enough to handle the low volume of traffic. Even then, they brought in knitting to keep themselves busy. Since the Central Office equipment and the PBX were in the same building, it was a reasonable task to tie-in the PBX to the general network. They then assigned an unused prefix to generate a pseudo-exchange. Calls coming into this pseudo-exchange were to be routed to the PBX and paesed out to the TV station on a special line. When the next Saturday night rolled around, the TV station announced a different number in the pseudo-exchange for each game. Actually, it didn't matter what number they used used, everything went to them anyhow but it added drama to the show. They didn't announce the number until half way through each game so the people at home could become anxious as their boards began to fill in. Everything worked well at the phone company except for one minor detail. They forgot about the switchboard. When all these calls came in on the PBX, the switchboard lit up like a Christmas tree. The poor operators were sure that the city had suffered a major calamity and they nearly had heart attacks. The next week, the switchboard was blocked out except for the couple of lines reserved for company use. This tale was related to me at the time by my father. He was in the Dial Traffic Engineering group at Mountain States Tel. & Tel., now U. S. West Communications etc. etc. etc. ( Why they ever adopted such an obnoxiously long name, snows me! ) It was his job to get something working in one week's time. Vernon C.

Calling the same number several times, you would sometimes receive ESS precise busy signal or ring, sometimes SXS "honker" busy or ring. Certain numbers always gave you SXS ring/busy etc. It always dial pulsed into the switch (whatever it was!). That all finally went away maybe 6 or 7 years ago.

One alternative is to program the number you wish to call into one of the "memories" of your telephone before you start your call in attempts. (Now everyone has a telephone with an n number memory, where n is somewhere between 3 and 100, don't they?) I've discovered that, on my AT&T 1600 telephone, the "redial" button can be programmed without dialing a call, just by using the same method as to program any of the other memory buttons.

I am a cordless phone neophyte with a question or two that I hope the group(s) can help me with. We gave my daughter our old kitchen phone last week (her first apartment), and went off in search of a cordless phone. We ended up at Sears because of a sales flyer. Experience has taught me never to buy the cheapest of anything (at least not in the techno-toys department), so I steered clear of the $52 special, and bought the $80 AT&T 4200. I took it home and found that while I could still hear, there was a bit of audible static & distortion when I went around a wall or two, and also when I went outside. I talked with a friend who was blissfully happy with his AT&T 5320, so I went back to Sears and took the 4200 back. They didn't have a 5320.. only a 5310 @ $175 or so. I compared features on the box with the 5200 (next model down that they carried) and it appeared on the surface that the 5310 was just a feature-fat version of the 5200. Since the latter was $134, I opted for it. Well - we still get some buzzing and static, sometimes even in close proximity to the base unit. Now what I'm wondering is: o - Is this just the nature of cordless phones, and should I just get used to it? o - Is the 5310 really worth the extra $40 or so ? o - Is there another make that I should check into? o - Is 'compression' a valued feature or a marketing gimmick? o - What are other folks' experiences and what are they using?

If you don't work in an office where this is a problem, you can't imagine how annoying it is. My office is in a large room with about 30 other offices. We all have Steelcase moveable wall type offices with the fabric finish. We also all have the traditional AT&T 2500 telephones on our desks. Unfortunately, they are the new electronic ringer style. With the traditional bell, it is possible to be in any one else's office and tell if your phone is ringing based on the volume and direction of the bell. With these new ringers, it is impossible to tell where the "warble" is coming from, even though you are only one office away. There seems to be no way the ear can attribute direction to the "warble". Hence, every time a phone rings, everyone runs to their office to see if it is for them. Several of us got tired of this and wired up a neon flasher. It's quite easy to make: You get a standard neon bulb (NE-2?) and a 10K resistor. Solder the resistor in line (not across) with the neon bulb. Remove the eraser from a Jet Eraser (or use a pen casing) and mount the bulb in the casing. Run the wiring to your phone tip and ring lines. When the phone rings, the neon light flashes. It does not interfere with the operation of the phone. Note that this only works with traditional phone systems. It probably will not work with the new electronic systems. Now when the phone rings, we look and see who's phone is flashing.

Is there a single person on the planet for whom that's helpful or convenient? B) How difficult would it be to modify the system so that when one placed a call to a forwarded number, they would first hear a short tone signifying that the call was being bumped? Unlike A), that would actually be informative and helpful. Miguel_Cruz@ub.cc.umich.edu [Moderator's Note: Regards (A), if you actually reach the party to whom you are forwarding, you are assured of dialing correctly. If you get a busy or no answer, it might be because you dialed a wrong number. By doing it a second time, telco is assured that your instructions match your intentions. Without this repeat-dialing verification, you might accidentally have forwarded to the wrong place. Regards (B), many people do not want you to know they are not at home/office, etc. They'd prefer that you assume they are wherever you dialed them at. And for residences, do you want to let a burglar know you are not home, due a 'forwarding tone' which tells him there is no one there to receive a call (or unauthorized visit)? At present, if you listen *closely* when dialing a centrex number with call forwarding on no answer, after the third ring you will hear a slightly out of synch ring the fourth time.

Here in the US, some pay phones, particularly those in airports, do in fact take regular credit cards. They have a slot through which you run the card so it can read the number magnetically, then you dial the number, then if the call is out of the local region, you push a button corresponding to the LD carrier you want to use, with typical choices being MCI, Sprint, and ITT. AT&T has their own distinctive looking card caller phones that used to take only AT&T's own card but now are also starting to take Amex and bank cards. In all these cases, the phone transmits the credit card number in a torrent of DTMF tones, so I suppose that if you knew the protocol you could type in the card number yourself. Entering a bank card number at the time when you would enter your phone card number doesn't work. I also once saw a COCOT at a car rental place in Denver that let you type in a bank card number yourself, and claimed that the charge for doing so was cheaper than that for a telco calling card. I can believe that; telcos are reputed to charge 75 cents apiece for billing OCC calls but I know that a bank charges more like 35 cents for an electronically submitted Master Card or Visa charge. The Airfones found on too many airplanes these days only take regular credit cards, not phone cards, but at $2.50/minute and terrible voice quality they're only for the desperate. John R.

It wasn't until years later that someone thought to provide them with chairs. - It was customary for a long while to answer the telephone with the word "Ahoy!" or with the phrase "Are you there?". The person who started the trend of answering the phone with the word "Hello" was Thomas Edison. - Speaking of Edison, the phone Edison designed for Western Union had a small magneto that wasn't used to signal the exchange. Rather, it was used to provide talk power, and thus it had to be wound continually while the phone was in operation. - The first telephones for private conversation in a public place were released by the GPO in England in the late 19th century. To use one, you would place the receiver up to your ear, and press your face into an oblong inner-tube that contained the transmitter. They didn't last long, however, as they were considered unsanitary and quite ridiculous. Gabe Wiener - Columbia Univ.

I remember when a friend went to buy a 2500 set a few Yes, the following companies still make real 500 and 2500 sets: ITT, Comdial (Stromberg Carlson), Northern Telecom?. Also North Supply (A phone equipment distributor) imports a made in Korea clone called the Premier. The Premier is not as robust as the others. It is cheaper, now you know why. The 500 set is a standard desk rotary, a 2500 is a standard desk Touch-Tone. The variations of these, wallphone etc have slightly different numbers such as 2600. A standard 500 or 2500 has interchangeable parts: The ringer from one will fit in the other. The handsets are interchangeable. The base from one will fit the cover of the other. Yes, you can have old AT&T guts tarted up with a new comdial plastic case and an ITT handset. All parts are available from suppliers such as North, so any of these phones can be repaired or reconditioned. In the telco trade, this is called R&R (repair and restoration). AT&T phone stores used to offer thier old 2500 sets as refurbed at a good price. This is a deal. As you can fix any of these phones, you can buy battered ones and repair and clean them up. You can also convert old non modular to modular. These sets are really tough, they have to pass tests involving repeated drops into concrete and voltage surges of 1,000V @ 1,000A. Automatic Electric (GTE) make versions of these sets that work fine, but are not interchangeable with the others. Another phone equipment supplier that can supply 2500 set parts is Graybar. No doubt about it. A 500 or 2500 will last forever. I just R&Red one for a friend that had a manufacturing date of 1954. Still in daily use, I made it modular and polished the plastic. If there is any interest, I can explain how to repair and tart up these phones. The phones I use are all 2500 sets. I have a garage of phones from around the world. Nothing matches the 2500. I have to admit though that the old style handset used in the UK was the most comfortable for cradling. It is longer and wider than the G2 (the standard handset on 500/2500). The UK operators headset was also more comfortable than the WECO black monsters but not as indestructable.

I don't know sets by their numbers, but if the 2500 is the standard, pre-buy-your-own-phone desk set with a roughly rectangular base, then the answer is that they are no longer manufactured, but that "refurbished" models are still available. In 1983 (or so), when Illinois Bell allowed you to purchase the phone you had been leasing from them at a discount, I did so. About 6 months ago the touchtones on my phone stopped working (no, it had nothing to do with line polarity -- that's the first thing I checked -- and it happened a few days after I dropped it on the floor, so maybe it was my fault) and I decided to get a new one. I was finally able to purchase a "refurbished" touchtone set exactly like my old one, for $49.95, direct from AT&T, but they told me that none of their new desk-model touchtone phones had mechanical ringers. (For the same price, AT&T said they'd fix my old phone, but that hardly seemed like a reasonable option). Also available for $49.95, they said, was an in-line modular mechanical bell attachment that would work with any phone, so for those who want the features of new phones and the sound of old ones, that might be worth considering. I decided to go with the complete phone. David Albert | "What are you trying to do, UUCP: ...!harvard!albert | change the world?"

Those were the 2500 'two line turn button' sets, with the plastic knob in the corner for selection of line one or two. The turn button also could be depressed, and the corresponding blue/white pair of wires (mine has three pairs, at least) used to sound an intercom buzzer elsewhere. Furthermore, I got a little neon bulb at Radio Shack and wired it in there so it would illuminate the little button when the phone rang. All that AT&T will do for you now is replace them one on one for *lease* customers only. Its a shame to see these great old sets no longer being built.

What happened here is that AT&T representatives wooed senior administrators; when time came to replace our old key system, which worked wonderfully but was at the limits of its capacity and couldn't be expanded, there was no technical evaluation of phone systems. We ended up getting some AT&T gee-whiz system with LEDs and whatnot. The telephones have to get wall power to work, insofar as they work at all, which is mostly not. This is lovely when you want to call to report that the power is out. The human engineering is pathetic. The system is constantly enjoying "software glitches" which prevent phones from ringing when they are called, or spontaneously trigger some kind of forwarding without illuminating the forwarding indicator. I don't have any reason to believe that AT&T weasles couldn't grease in to enough other organizations the same way to make for a profitable business. I'm pretty sure I understand the precise reasons for the design changes; the new phones offer the following benefits: 1. They charge disproportionately much for them. 2. They are more fragile than the older ones -- which means that they will have to be replaced sooner. 3. The poor fools who actually have to *use* the damned things loathe them, so when the weasles come along and sell management on a whole new replacement system in two or three years, there won't be anything like the complaints that rang through the office when the old key system with the old massive phones was taken out. Equipment lifetimes of several decades aren't so good for repeat sales. However, this isn't all to our loss. I used to think that having a telephone was really important. I have been cured of this belief. Between GTE and AT&T, I don't particularly worry about being hard to reach by phone at work, and impossible at home. -Bennett bet@orion.mc.duke.edu [Moderator's Note: But Bennett, if it weren't for your phone -- or someone's phone -- how would you receive this Digest each day?

You punch >in the entire number, then 'send' it.

Cellular phones let you enter the number then press the $pend key. They then broadcast the NAM and phone id stuff on a broadcast freq, after which the selected cell site passes back the freq pair to use. Now, the phone number (if there is one) goes out. All the cel-phones I have worked with have a button ususally labled "clr" that allows you to "backspace" one charicter by just touching it once, or the whole number by holding it down. Unfortunately some of them, like my Motorola 8000x, have about a quarter second delay after you press the button before they go into the clear_the_whole_number mode. This is almost too fast and it takes some getting used to, when you want to backspace just once. Triva note: DTMF isn't used to send the phone number, even though most cel-phones echo DTMF sounds while you press the buttons. After a connection is established, usually the phone will then revert to sending DTMF out as audio. As far as regular phones, my (I can't believe I'm admitting this) GTE Xt-100e phone terminal, (vt100 terminal and a telephone built in) lets you backspace and edit the number before pushing the outgoing line button. I also have some off brand two line phone purchased a couple of years ago that has a <- key which lets you backup a digit. It too only sends the entire number after you select an outgoing line. It's problem is that it only holds 15 digits and dactivates the touch tone pad after the line select has gone out... Quite a pain on long numbers, I usually have to program a combination of speed dials into it (which don't deactivate unless they are used) to reach anybody except direct dial on my primary LD carrier. Anyway those keys are rarely used, generally when I make a mistake in dialing it was on of the first digits of the number and I end up starting over anyway..

OCR can work for the searching part. 99% character recognition rates are common. There are already products available that scan, recognize, and index documents for you. The key idea is that the image is saved too, so there is no danger of the 1% missed characters causing problems other than missed retrieval. As for editing, very often one wants only to annotate another document. This can be done on the image. If one really wants to edit a document, OCR plus some hand massaging may suffice. > The reason why telefax will supplant email unless email is separated > from special networks is that telefax works by using the existing > telephone network directly.

This is a very big proviso. There is great chaos in this area right now. The standard proposed by CCITT, called Office Document Architecture (ODA), is getting very little support in the US where the DoD seems to be promoting SGML and the commercial document editor vendors are promoting their own proprietary standards. MicroSoft's Rich Text Format (RTF) seems most promising since it is used by more than one document processor. Another hope is that a single vendor, e.g. DEC with it's ODA-related DDIF and DECWrite (=Framemaker), will become the market leader and establish a de facto standard, as Lotus did for spread sheets. A much more likely development is that PostScript becomes the exchange standard. It is there. All document processors will produce it. It looks a little nicer than FAX, and there is at least a fighting chance that one can translate it back into a particular document processor's internal format. Another advantage of FAX you failed to emphasize is simply that it deals with pictures effortlessly. Even if you and I have precisely the same computing equipment and are on the ArpaNet, the fastest way for me to get a picture to you is FAX. This is true even if the picture is hand drawn -- drawing it on paper is faster than any drawing editor I've ever used. > Fortunately, there is free enterprise.

The figure '7' is on the "shifted" character set (same character code as the letter 'U', 0b00111). The had the same code as the letter 'J' (0b01011). ) Weren't the 'number-shift' keys essentially like control keys? Presuming that you mean the "shift" (FIGS) and "unshift" ("LTRS") keys, no, they weren't like control keys. They differed in two important ways. First, they sent character codes. Secondly, they had no printing effect themselves, but caused later characters to be printed from a possibly different charset. ) How did they get line feed, carriage return, There are baudot codes for CR and LF. These, interestingly enough, are effective in both shifted and unshifted modes. ) ENQ (who are you?) You typed "WHO DAT?" and stopped typing. ) and answerback without control codes? The other guy typed "IT'S ME." in response. He might have had a tape reader in which case he could have this text prepared for your editfication; it would save him typing it again. ) My handy Ascii chart here says control-E, or ASC(5) It should be noted that ASCII is not a 5-level code. When discussing the 5-level devices, refer not to your ASCII chart but to a BAUDOT chart instead. ) What do you think? PT] I think that you haven't worked on many 5-level devices, to be honest. These slow devices (noisy, too) are pretty much unrelated to any modern computing needs. I only ever heard of one general-purpose computer system which purported to support the things, and never actually saw it done. Please see the [Radio Amateur's Handbook] for information on the BAUDOT code. You might also consult a maint manual for a model 15/model 19 teleprinter. The original wiring on these devices is somewhat baroque. Considering that very little of it is actually needed (a common maint trick is to remove the old wiring, add the 10 or so wires needed in the whole device, and try to figure out what to do with the many, many feet of old wire. It has been thought that perhaps the added wiring was for the military - whether to confuse the enemy, or just to raise the price, has not been determined. The characters in the FIGS set, by the way, were somewhat variable depending on the particular unit in hand. On some, you could get motor stop instead of one of the printing characters (I think that you might have been able to configure which you got). On others, you might not have the prime ('). Other units had weather symbols instead of some of the figures. ...!bikini.cis.ufl.edu!ki4pv!tanner ...!bpa!cdin-1!ki4pv!tanner or... {allegra attctc gatech!uflorida uunet!cdin-1}!ki4pv!tanner ------------------------------ Date: Thu, 28 Sep 89 00:00:58 PDT From: Jim Budler Subject: Re: They're Doing It Again (was Chicago Cubs Trash Bell) Organization: EDA Systems, Inc. claris!netcom!edg@ames.arc.nasa.gov (Edward Greenberg) writes: } "The A's announced plans for sale of tickets for any American League } Championship Series at the Coliseum. } Phone numbers are in the 408-988, 415-762, 707-762, 916-932, 209-226, } 209-466, and 1-800-225 prefixes.

That was stupid short-sightedness in my opinion, as that would have made life easier for many, including DJs, who would have been able to say, "In the 213, 818, or 714, dial 520-KQLZ" instead of the now-required awkward practice of having to give out two different numbers. On the matter of mass calling to ticket numbers, I know for a fact that Ticketron's numbers in the LA area, while being standard POTS lines, are programmed to choke in each switch, and probably in the tandems as well.

I have lived here in South Florida for about 7 years now and have been involved in broadcasting since I moved here. I used to be chief engineer of a TV station down here and at the time we had some audience participation shows on the air. This same discussion holds true for radio stations in the area. This area has always been known for its telephone contesting. That is, people are told to be the thus and such caller and they win something. This had caused exchange overload in a very highly concentrated area. Normally the phone company would have said too bad, but since there are several military establishments that feed off some of these key COs, something had to be done. I don't know if this has been done in other parts of the country, but ALL radio stations and TV stations that do any kind of phone contesting have special lines installed here. All lines are part of the 550 exchange from South Miami through to West Palm Beach. These are called "choke exchanges." As far as the caller in concerned, there is only one number to call, beginning with 550. In each exchange area, this 550 number is translated into a local exchange number and then FXed back to the station. If memory serves, we actually had 4 different sets of FX lines. They were Miami, Ft. Lauderdale, Deerfield and Palm Beach. We paid plenty for them! What was interesting was these lines were specially translated at each CO point, but were ordinary FX lines for outgoing purposes. I had them wired up to our PABX so that I could make calls to any of these areas. The reason they are called "choke exchanges" is that to prevent CO lockup, only two calls from each exchange are allowed to go inter CO. The rest of the calls get a local exchange reorder. Hence, the exchange chokes off the calls before they can cause network overload. In theory, its a good idea, but in practice there are problems.

Of course most people don't know that most push-button phones are capable of pulse dialing and may not even have a DTMF generator! So you wind up paying for a service that you can't even use. It seems the phone companies should be required to call it DTMF service or tone service, not push-button service. Jerry Durand ------------------------------ From: John Higdon Subject: Re: Sleazy Touch-Tone Marketing Tactics Date: 28 Sep 89 10:07:39 GMT Organization: Green Hills and Cows Years ago, one of my clients had a Stromberg E120 connected to a #5 crossbar exchange. Somehow the trunks went in without touchtone specified and as a result the customer was not paying for it, but in this particular office tone service could not be denied (apparently there were no originating registers not tone receiver equipped). Their bookkeeper called me one day to complain that suddenly the basic rate had gone up and wanted me to look into it. I was told by Pacific Telephone that one of their "agents" had gone through the building looking for businesses that were using touchtone and not paying for it and had spotted the TT phones in my client's suite. I told them that since those phones were connected to a PBX that it was possible that the customer's switch could be doing tone-to-pulse conversion and that simply tacking charges onto the bill based upon visual inspection was very sleazy. In fact, I told them such was the case (I lied) and demanded that the charges be removed immediately. They asked for assurance that absolutely no tones were being sent over the lines. I refused and told them to simply "remove the touch tone service". They warned me that if they did and the customer was indeed using tones to dial calls, then their calls would no longer go through. I acknowledged that and again asked to have the service removed. It finally came down to the fact they couldn't "remove" the service. At this point I told them that my client wasn't going to pay for something "extra" that PacTel was forced to provide for everyone anyway. My final position was that if they were providing a "cost extra" service and we didn't pay for it, then take it away. But we weren't going to pay. Apparently, the tariffs were written in such a way to allow me to get away with this tactic. I had PacTel over a barrel and they knew it. Then a supervisor said that when they cut over to new equipment, they *would* be able to deny touchtone and that my client would be screwed. I countered that we would pay for it *then*. As it turned out, years later when they cut crossbar offices to electronic, they would send out notices that in essence indicated that if you had touchtone equipment and were not subscribing to the service that you would have to start subscribing and paying or have your calls not go through. It is interesting to note that this particular exchange is still crossbar to this day but unfortunately my client moved into an ESS office and now has to pay for touchtone. John Higdon | P. O.

In 1969, the only customer on 856 was the Amoco Oil Credit Card Office here, when the prefix was opened for them with their new centrex service, serving about 2000 lines. All the phones were touchtone. Over one weekend in 1974, that office was converted to ESS. Monday morning, about half the phones in the place could not dial out. Unlike merely a change in polarity, where the buttons do not sound their tones, this time the tones sounded alright, they just wouldn't cut the dial tone! With some feverish effort, everything was properly working by Tuesday morning. And the funny thing was, Amoco *was* paying for touchtone on all the lines, but the CO records were wrong!

If the number displayed is that of the originating phone, is there any heirarchy of displays -- that is, if the originating phone is out of the area and the number isn't available, but the number of the forwarding phone IS available, will the forwarding-phone's number be displayed in that case?

So, how would > both telephones perform call set up and tear down on the one D channel? First, the D-channel is a packet channel, so each message sent down the D-channel from the CPE to the switch is independent. The basic call control protocol for ISDN is Q.931. One required information element of each Q.931 message is the call reference value; this enables the machines on each side of the interface to agree on what call they're acting on. So when the CPE sends, for example, a Disconnect message, one information element is a call reference -- essentially, saying Disconnect Call #1. In addition, there is an optional information element in Setup and Connect Q.931 messages, called the Channel Identification information element. This enables the CPE to specify a specific channel, either at that user-network interface or at another user-network interface. In other words, CPE can send a message to the switch saying "setup a call on this UNI, B-channel 1." Or, "setup a call on UNI X, B-channel 2." It's not clear that all the wrinkles have been worked out of the latter case, tho...

This is something I understand Pac*Bell has been perpetrating for some time, I have previously been fortunate enough to avoid it. Dial 611. "Welcome to Pacific Bell's automated repair service." First they determine if you have a touch tone phone by asking for a "1". Then you are told that if you want a live person, you press "0". If you take the automatic bait, you first enter the number that is experiencing the difficulty. After that you are given a menu of maladies such as no dial tone, noise or static, etc. If your trouble doesn't fit any category, you will have to press the "0" for a person. After selecting your trouble, you give a number where you can be reached during the day. Then you get a summary made up of assembled phrases complete with a promised due date. This whole procedure takes somewhat longer than an ordinary person and seems to be geared to an eight-year-old mentality. Lest you think that I am against progress, here are some points to consider: This could be a good cost-cutting measure by reducing personnel, however I doubt that the remaining attendants will be any better trained than before, so it could just be an extra step in the repair-reporting process. The major manpower is used in the followup, not in taking the original complaint. I question whether this system can save them much. As for me and my house, I'm through calling 611. Future repair requests will be made directly to 811-8081, the priority repair number. When you call that number, you get a real person who knows exactly what's what. The trouble is handed to a tech who gets back to you in 30 minutes with a report and you get a direct call back number for inquiries that is answered by the person actually effecting the repairs. This is the number that I have used for my big customers and it suddenly occured to me that I was wasting my time ever fooling around with 611! John Higdon | P. O.

She needs to get her first line operating as quickly as possible. The important thing is to get people to take her order for service, assign a telephone number, and flick a switch in the CO to bring the line to life. When she was last in New York a couple weeks ago, NYTel told her that because of the strike the processing would take six weeks! Her line of work is such that she needs to be able to receive emergency calls. Do any of the readers know any means (or even anybody) that can speed things up at NYTel, at least for getting her first line turned on?

HAMER" Subject: Credit Card Good For One Number Only I think that aspects of this issue have been discussed on the digest before, and if they have, if the moderator would point me to the appropriate issues, I will FTP them (unless the question is of sufficient general interest that it might bear discussion). My daughter just left for college (hooray). When she left, my wife gave her our Sprint Fon Card number so that she could call us (probably a dumb move, or at least not well thought out). We got our first post-daughter-departure Sprint bill yesterday. In addition to two or three calls to us, there were calls to friends and relatives all over the country. To state the specifications first, without contaminating possible solutions with my own thoughts, I would like her to be able to call us at our expense, but I have no particular desire to pay for any other long distance calls she chooses to make. I think I have read discussions in this digest about (a) a relatively cheap residential 800 number, and/or calling/fon/credit cards that are valid only to call one number. Anyone have any suggestions? [Moderator's Note: The AT&T Calling Card with a restricted PIN is known as the "Call Me" Card. It is free for the asking, and the PIN is limited to calling only the number to which it is assigned; in this case, that would be your home phone. They issue a plastic card with this PIN, but it is pointless to hand it out. You would simply tell your daughter that henceforth to call *you, and you only* she would dial zero, plus the area code and your number. When she hears the tone, dial only the four digits of the (new, and restricted) PIN, followed by the # sign to speed the call on its way. Attempts to call other numbers with that PIN will fail. Of course, you'll need to tell Sprint to cancel your existing full service PIN and issue a new number which you don't give your daughter, otherwise she may continue using the old one anyway. Anyone who has knowledge of the restricted PIN can use it in the same way, to call your number only. If calls are placed through some AOS outfit, there is no guarentee of course that the restriction on the PIN would be honored, but you will find that out soon enough and can refuse payment if necessary.

Since this is fairly easy to do (we have two DSP's on the board, one dedicated to call progress), we will be adding this to some future software release. The question is, we have not been able to find any phone lines that allow the calling party to pulse dial any number higher than 2 or 3 without dropping the line. Is this just local to our area (GTE, Pac*Bell), or is this a widespread problem. I know there is a company selling boards that just detect the inbound pulses, so there must be some place it works. Please note: I am not talking about loop current detect, just the sound of the clicks transmitted through the network from the calling party. Jerry Durand, Durand Interstellar, Inc., sun!cup.portal.com!jdurand [Moderator's Note: Interestingly enough, United Airlines was doing this on the Chicago dialup to their Unitel network several years ago. If you dialed a certain number, you got dialtone from United's internal system, and could dial everywhere United flies and then some; or use the WATS lines, etc. This particular WATS-extender, as they are called, not only worked on tone signals as you would expect, but also accepted rotary dialing from the caller. Don't ask me how! But the deeper you got in the maze -- they used 'progressive dialing' as it was called in those days -- only tones would work. But a simple call in with a single hop, such as onto the WATS line and out again worked fine with rotary dial. Beats me.

And he further notes that "area codes" are called "STD codes" whether the subscriber is actually placing the call or not. He also notes that I was wrong to remember radio station 3BZ in Christchurch; it's actually 3ZB. (Formally, ZL3ZB, it seems.) He said that digits 1-4 are used for different parts of the country, but there was once a station 5ZB, which broadcast from a railway car! And *I* note that when I was there in 1983, on one occasion I found myself placing a call from a hand-cranked phone, and on another occasion there occurred the following conversation between my friend and an operator. (I've posted this to Telecom before but perhaps it's worth repeating.) "I'd like to make a transferred-charge call to Milford Sound. Please charge it to Spencerville 269." "Spencerville 269, and you're calling Milford Sound 6." "How did you know??!" "It's the only telephone in Milford Sound." "!" "Except for the box outside the post office, and I didn't think you'd be calling that." It should be noted that he could have direct-dialed, um pardon me, placed an STD call, if he had not wanted to transfer the charge. By the way, local calls from a payphone were then 6 cents... the only coin slots on the phones being 2 and 10 cents. Fun country. The backward dial numbering has already been noted.

The phone will ring and I will pick it up on about the third ring, only to get immediate dial tone. Nobody who places genuine calls to my house gives up that fast, so it's not someone abandoning the call just as I pick up the tone. There's no period of silence at the other end, so it's not a modem/FAX call. Not even a short period of silence, as one would expect with "a burglar calling to see if anyone is home". Could this be some sort of phenomonen originating at the switch? I'm in area code 416, prefix 488; Bell Canada evidently has a relatively modern switch there, as things like Call Waiting and Three-Way Calling are available. When I call another number within 488, the ringback usually comes instantly as I let go of the 7th pushbutton. But I don't know what model it actually is.

Winstead" Subject: International Calling Request? Hello, I'm looking for documentation on making long distance calls from the US to other countries. Specificly I would like to know the number of digits in telephone numbers for different countries. I have access to various documents which list Country and City Codes. What I need to know is how many digits should follow these codes. I have seen from numbers that work that this is not always the same for all countries. The main campus library has a fair collection of International/UN/US government documents. So even a pointer to some CCITT paper or such would be helpful. I'm requesting this because part of my job is to send FAXes for people who are sometimes confused about international telephoning. Thanks, Frank Winstead [Moderator's Note: The number of digits following varies from country to country, and frequently, even within a country. That is why AT&T encourages the use of the '#' button as a terminator, or carriage return following the final digit on international calls. It tells our system here to go ahead and process what it has been given without waiting for more. Perhaps if you have specific countries in mind, Mr. Covert will respond to you in email. He is our 'resident expert' on international calls here in the Digest readership. By the way, the '#' button also speeds along calls in any instance in which the network would otherwise have to wait for a time out. For example, when dialing the number associated with a Calling Card, one need only enter the four digit PIN; yet the switch does not know that is what you are doing, and will wait patiently for the other ten digits of the card for a few seconds unless you terminate with # to speed the processing. 'Zero pound' hastens the operator in Chicago, I might add. PT] ------------------------------ From: "Mark A. Holtz" Subject: The "Junk Fax" Bill in California Date: 29 Sep 89 03:30:50 GMT Organization: Sacramento Public Access, Ca. USA Quite recently, a bill was passed through both houses of the California legislature which prohibits unsolicited "junk fax" from being sent. The basis: Regular junk mail costs nothing more than the time to toss it into file 13, which you pay for the ink and paper for junk fax. However, the governor of California has stated that he would not sign said bill. He is bound to change his mind. Several radio stations have gotten a hold of the Governor's fax number. And, they have given it out, telling people to keep the fax machine busy with junk fax. And, sure enough, it has been busy. If you were the governor of California, would you sign the "Junk Fax" bill now?

What I might do instead would be send a courteous note back to all the numbers which had junk-faxed me telling them if they continued that sort of harassment they would get sued. And I would tell the radio station management that using my position as governor, I would communicate with the FCC and file a formal complaint against them for encouraging telephonic harassment over the airwaves.

This was in about 1963-5 and was done on a computer owned by Honeywell and destined for use an a switcher to replace the room full of clerks who took papertape output from one of some 20 punches and manually fed them to some other reader in the same room. The system was used for a private telegraph system operated by Honey- well. It did not work for some reason, so the machine was left nearly idle. (this was during the day of the IBM 1401 computer.) One of my associates at the Honewell Research Center, a Mr. Keith Betz, programmed this fairly old computer to use the the baudot lines as on-line terminal connectors to give 12 simultaneous tasks on 12 isolated terminals. Entering a line such as A = B + C required 4 case changes as the spcial symbols and numbers were in a different case than the letters. We loved it at the time. 75 baud, papertape, yellow paper and all. The alternative was to submit card decks to a computer across town with 8 (eight) day turnaround. Jobs sumbitted on Monday came back the next Tuesday, just too late to correct and resubmit. Work was accepted on Monday only. + - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - + | Leonard P.

Covert 28-Sep-1989 2142" Subject: AT&T Blows Billing on Call To Shoup Salmon River Store You may remember my call to the Shoup Salmon River store. This was part of my article back on 8 August: >More interesting is the system in Shoup, Idaho. Call 208 555-1212 >and ask for the Shoup Salmon River store -- you'll be told to call >Shoup 24F3.

Well, the bill arrived, and AT&T blew it badly. I have the following entry on my bill for the period August 20-September 19: No. Date Time Place Area-Number * Min:Sec Amount 1 Aug 7 1000PM EGYPT 208057121 R 5 8.27 When I saw this, I knew no one had called Egypt from my phone, and I called AT&T to have the call taken off the bill. The AT&T rep insisted that the "R" meant that the call had been direct dialled from my phone (not actually true; if I had been unable to dial for some reason it would have still been charged at the "R" rate). I insisted that the call had not been placed from my phone and that there must be some sort of error. I pointed out that I thought that it was strange that the call was outside the billing period and that it was at exactly 1000PM, indicating that there may have been some sort of manual ticketing involved. AT&T agreed to take the call off the bill. Then, tonight, I mentioned the spurious call to Egypt to someone I know who has half the toll-completing codes (or maybe all of them) memorized from the old days when they were easily hackable. He immediately said, "Well, if it wasn't Egypt, it would have been Salmon, Idaho." The light went on! I remembered the call to the Shoup Store. Wanting to correct the problem and to prevent an AT&T security investigation of the supposed call to Egypt, I called AT&T again to explain what had actually happened and to offer to pay for the five minute call to Idaho. The service rep I talked to really couldn't understand what I was talking about and told me that if AT&T had agreed to take the Egypt call off the bill, that was that, and I could have the call to Idaho for free. Clearly either TSPS blew the automated ticketing or the operator marked the manual ticket incorrectly. /john ------------------------------ Date: Fri, 29 Sep 89 09:49:37 EDT From: Bernard Mckeever Subject: Tickets and No Dial Tone Reply-To: bmk@cbnews.ATT.COM (bernard.mckeever,54236,mv,3b045,508 960 6289) Organization: AT&T Bell Laboratories Sounds like IBT and PAC BELL have lots to look out for in the next few weeks. When the Cubs get in the World Series this could happen again. A quick note to our moderator that I will share with others. Patrick, you mentioned that during heavy traffic when dial tone is delayed that you stay off hook and use your speaker phone to detect dial tone. As I recall in an article published in the local operating company internal newspaper [pre-divestiture], all ESS machines were being re-programmed with a new algorithm for heavy traffic. They will now process the last offered call first. The reasons that were stated at the time were: 1. The call had a better chance of compleating because the caller was unlikely to abandon the call when dial tone appears in the normal time frame. 2. Many more callers would be unaware of the problem because most people do not make multiple calls. 3. Retries would be fewer because calls with a low probability of completion would wait the longest for dial tone. Anyway this is about as close as I can recall from memory. Can somebody from IH shed some light on this. ------------------------------ Date: Fri, 29 Sep 89 05:38:08 EDT From: jsol@bu-it.bu.edu Subject: Intelledial on Two Lines I have two lines here too, one for data, and one for voice (I've ordered a third line but it's held up because of the strike). What I'd recommend is to put intelledial on your two lines (it's 9.00/mo/line) and use the "call hold" feature to do the transferring on one line. What I mean is this: You get a call on your voice line you answer it, it's for your wife. you say "hold on a minute", flash the switchook, then dial *9, and then hang up. The phone will ring. Your wife answers the fone after 4 or so rings realizing you won't be getting it....... You don't really need intercom for that. One thing you might want to try is using your fax line as a second line for intercom purposes and outside calls only. If your fax line is busy for a few short minutes while you ring the other line, it shouldn't be a problem. That is if you want an intercom. If the above situation is okay with you (dialing *9, etc), then you don't need any more lines. --jsol p.s. Intellidial is great! [Moderator's Note: It sure is! Here we call it Starline, but it is the same difference. I don't think I would ever go back to having a PBX.

Date: 29 Sep 89 03:28:32 GMT Reply-To: Edward Greenberg Organization: NetCom- The Bay Area's Public Access Unix System {408 997-9175} On Long Island, New York, the verification operator went away in about 1980. In the early 70's, one verified by calling the operator and asking for "verification on 555-2368." The operator would call the number and, if s/he got a busy, call the verification operator for you and ask for "verification on 555-2368." The verification operator would answer "busy talking" or "out of service, I'll report it." We soon learned that we could reach the verification operator by dialing the affected prefix and 9901 (or, "official 1"). Then WE could tell the verification operator to do her thing. In about 1973 or '74, we could no longer reach a verification operator on official-1, but rather, 234-9901 would bring one up capable of verifying anywhere in 516. In about 1980, as I said above, the operators started verifying (and doing emergency cut-in's) themselves. -edg P.S. Does anybody else remember using verification as an early form of call waiting? Ed Greenberg uunet!apple!netcom!edg [Moderator's Note: Yes, we used to ask for verification which would cause a click on the other person's line, as a way of letting them know someone wanted them. Abuse of it is why they now charge for verifying if the line does in fact test busy and not out of order. When we then got through, the other party would always ask, "was that you trying to get me?", and I would always reply, "did the operator cut in and tell you to can the sh-- and give someone else a chance to get through on the line?" :) PT] ------------------------------ From: "John R.

If you want to go all the way back, the 0th split was probably 201/609. The earliest NPA maps apparently had all of New Jersey in 201, but they split it before many people even had DDD. One thing I've always wondered about was why 201 is a single LATA, while 609, which has about half as many phones and prefixes, it split into two. I suppose it's because 609 has a strip of nearly uninhabited Pine Barrens down the middle which makes it easy to split, but it's a pain. The eastern 609 LATA is a tiny strip running about 65 miles down the coast with the only town of any size being Atlantic City. I happen to have a beach house near there and almost every call I make is an inter-lata toll call. At least they all go toward my Sprint Plus volume discount. This situation also makes for some interesting dialing. From my parents' house in Princeton NJ in the western 609 LATA, when you dial a regular seven digit number it might be: * a free local intra-lata call * a free local inter-lata call, since local calls into adjacent prefixes in 201 can still be dialed without the area code * an intra-lata toll call * an inter-lata toll call It makes it hard to tell how much to expect to pay. Local calls across the NPA boundary can be dialed without the area code all along the line in New Jersey, and since there are still several NNX prefixes that are assigned neither in 201 nor 609, this seems unlikely to change. 609 does not have NXX prefixes but 201 does, and in at least one case an NXX prefix in Toms River (201) is dialable from Barnegat (609) without an area code; I guess they had to put in a special case timeout.

A friend bought a bunch of these cases and uses them to R & R 2500 sets as novelty items. Everything is clear. The handset, base, faceplate and, of course, the cover over the number card. One of these days I'm going to laser print my phone number onto a transparency so that can be clear too. A marblized green and white Stromberg Carlson trimline. This one was picked up in a phone wholesaler on closeout. The story was that a line of these had been designed for a Hawaiian hotel that got into financial trouble during construction. It went well with a green bathroom that I no longer have. My wife won't let it see the light of day any more though. A beige, five line touchtone card dialer. I gotta find a place to put this one in the house... It's just too nice to keep in a box. Unfortunately, there ain't anyplace in the current residence that needs a phone. This one is programmed by punching out holes in cards. You have to punch two holes per number. One for the row and one for the column. Inside, it's mechanical and electrical madness. I wonder if (where) I could still get cards. An "ITT/Kellogg" 576 set. This is one with three lines and three manual holds. It has ROUND buttons, and has to have hookswitch key restoration on the hold buttons, in order not to busy out the lines forever. It also has neon ring indicators on the line buttons, and provisions to wire a supply to provide lights for on-hold indications. This phone has a Numeric dial, rather than a "metropolitan" one. That means it has ten LARGE digits (in standard rotary dial digit font) instead of ten smaller digits with letter codes next to them. What other pieces of history do we have out there? Ed Greenberg uunet!apple!netcom!edg [Moderator's Note: I've got a 'French-style' phone: the round, fat base with the felt covering the bottom, the sort of skinny neck and the four fingers -- two extended upright on either side - which form the cradle. It has a rather large, heavy receiver, and *straight, brown cloth cord* from the receiver to the base, and from the base to where it was tied on by its spade lugs to the side-ringer on the wall. Rotary dial, of course, with a 'Z' on the Operator hole. Inside the unit on the bottom plate is the notation 'manufactured by Western Electric Hawthorne Works, 3-15-1927'. Bell phones of that era did not have bells in them. The bell was always in a box mounted on the wall; what we would today term a side-ringer, as is used for the second line on a two line phone. It still works, but the transmission quality is poor.

While these stored-value cards are definitely convenient and one avoids calling card surcharges, they always seemed to me to be too susceptible to fraud. After all, the sole record of your balance is sitting on the card in your pocket. Well, today's Japan Times reports the case of someone who was charged with buying cards with 50 10-yen (about 7 U.S. cents) units on them and reprogramming them with several thousand units and then selling them. Surprisingly, the case was dropped because the court determined that this person had not broken any laws! They said that since he had not planned to use the cards himself, he had not cheated the phone company out of any money. And since he dutifully informed the people he sold the cards to that they had been modified, he was not guilty of any securities law violation. I suspect that the Diet will need to quickly come up with a law to make this illegal, or a massive industry will sprout, with no fear of prosecution.

I agree with the moderator that letting the caller know that the call has been forwarded will defeat one of the selling points of that feature, but if the receipients aren't aware that the call they're getting is forwarded, they may accidentally give away that information through their fumbling. If the receipients got a coded ring, then they would be forewarned (e.g., if the person who set up call forwarding was in their home, that person could answer the phone; if your relative or friend forwarded to you while you were on vacation, you would know when you answered where you were supposed to pretend you're at). In an office, this would be even more useful. Before desktop terminals became the standard, and terminal rooms were the norm, people who would be working at terminals for several hours would often call-forward to the terminal room. When they forgot to remove call-forwarding, the person who picked up the phone in the terminal room would often just say that so&so wasn't there, or that this wasn't that person's phone (the latter would also happen if calls were left forwarded to someone else's desk, because you knew you would be in their office for a long time). At least with a coded ring, there would be no puzzlement to receipients as to why callers apparently got a wrong number.

This can be used to send mail here. It forwards direct, and eliminates the former hassle of two step addressing for Fido people. Telecom Digest 129/87 from any Fido node via netmail will terminate at 'hogbbs.fido.com' and be forwarded right out to me here in Evanston. My thanks to Mr. Fenner for making this alias available on his system. Speaking of addresses, here is a complete list of addresses which can be used to write TELECOM Digest. If one does not work for you for some reason, then another one might. telecom@eecs.nwu.edu (preferred address, for submissions) telecom-request@eecs.nwu.edu (preferred address for list changes, etc) telecom@cs.bu.edu (a backup address if eecs lets you down) telecom@hogbbs.fido.com (another backup address) telecom@nuacca.bitnet (for Bitnet correspondents) Telecom Digest 129/87 (for use from Fido sites) (telecom 129/87 also works) ptownson@eecs.nwu.edu (for personal mail to me) 155296378 (ans:ptown) (Telex; slower, but eventually forwards here) For next: Every letter sent to the above addresses (except ptownson and telex) generates an autoreply message from here. This lets you know your mail/Digest submission was received, and when it got here. Sometimes autoreply fails, for various reasons, but usually because some site along the way messes up the 'from:' line on your message, and the autoreply itself bounces back to me. Just because you don't get one, don't assume I did not get your mail unless a few days pass and you still have heard nothing -- not even a 'real' reply from me. Finally, the mail: As much as I would love to, I have absoutely no control over the delivery of Digests. Delivery on the Internet is pretty predictable, but off the net to Usenet, Bitnet, Compuserve, etc is anyone's guess regards time of delivery, etc. Please note that each issue of the Digest leaves here in numerical order, spaced at least 40-60 minutes apart. If you get them by the boatload -- a dozen one day and none the next -- there is nothing I can do about it, sorry. If you are missing a copy, let me know, because I can always send replacements.

Now while nothing classified is discussed on the (so-called) black phone, how happy are these folks going to be on the ID question? Will they be able to get ID blocked?

To set up call-forwarding, you need to make (and, if applicable, pay for) a call, like it or not. (Well, an alternative is to place two calls, hanging up before either is answered, not exactly to the delight of whomever you're forwarding the calls to.) Patrick's remarks are valid (I appreciate that it would be a drag to be the recipient of erroneously forwarded calls), but we endure several inconveniences the way things are.

Here's another anecdote about a famous person's work at a telegraph office. As a boy, Andrew Carnegie worked delivering telegrams. Apparently, in the early days, they did not believe that people could learn to read the telegraph by ear. They had a stylus attached to the "clicker", which drew lines on a strip of paper which was moved along the instrument. As the paper moved along, an incoming dot lifted the stylus up to make sort of a short rectangle on the paper; a dash made a long rectangle. A man would go over the strip of paper afterward, and "read" the message, type it out, and give it to a boy to be delivered. Carnegie mentions in his autobiography, that, from hanging around in the office, hearing the incoming clicks, and reading the messages before delivering them, he gradually learned to decode the messages in his head. Apparently this gave him an advantage, in that he knew the message even before the official "interpreter". I guess he could call out the message as it came in, and the other guy could just type it out, without having to look at the strip. Anyway, eventually they figured out that people could learn to read the clicks by ear.

Good idea, but not exactly FCC spec ;-) I have a commercial product from Radio Shack called the "Phone Flasher" it's basically the same thing as what you described only it's a real live consumer product. Cost was 7.95 a year or so ago. I have also seen these little critters in Target so I suspect that they are pretty widespread. There are several variants of them as well one that has a Xenon lamp in it, instead of Neon, another with a "tunable pitch" noise-maker in it, and lastly one that provides you a 120VAC outlet that comes on when the phone rings and goes off a few seconds after it stops. I guess if the Neon or the Xenon version wasn't enough light you could always connect that one to your Bat-Signal(tm). Oh yeah, I have one of those in my garage connected to a 12vdc transformer attached to a car horn, never miss a call when making lots of racket out there anymore ;-) If its of interest I can dig up and post RS catalog numbers for all of them.

No. You always get the originating phone. Thus, if the originator is out of area, but the forwarder is in area, caller*id shows "out of area". More Caller*ID tidbits: It is possible for the little Caller*ID unit to not even notice that a call came in if you pick up the phone very shortly after the first ring. This is because the Caller*ID info gets transmitted between rings, and it is possible to pick up before any info gets sent. This is pretty annoying. Also, not all exchanges in the same town will be in area. We have seven phone lines in my house on five different exchanges, all in the same town. (It's a long story, but it sure is fun having a 25-pair block in the basement installed by NJ Bell). Calls from two of the exchanges show up as "out of area", even though they are from the next room.

For instance, every point in Alaska except one is in the 907 area code (as one might expect). Hyder, AK is *only* reachable via 604 (BC). Why should this be? Probably, if I found that place on a map, it would be adjacent to the BC border, and presumably, close to a Canadian switch of some description. However, why can't the routing tables reflect this reality and allow us to use 907? Coudn't there be a "logical foreign exchange" within a host area code? Or would that be too much work for such a small community? This is also true of: Zones 6-8 in Wheeling, VW (Ohio area code). Some miles on the Alaska highway, BC (AB area code). Quite a few places in SK (AB area code). Further strangeness: For Nevada and Yukon Terr, every point is listed out explicitly with the area code, rather than the summary "All Points, area code...". Implication being that there were points in NV that had a UT/CA/AZ/OR area code, but are now genuine 702 area code, but that Bellcore has forgotten to update the directory appropriately? Peter Clitherow [Moderator's Note: I think the reasoning for listing out all dialable cities in Nevada and Yukon Territory is that if anything, those two areas are less likely to be dialable than most other states or provinces. For example, in Nevada, there are still a large number of toll stations -- places which cannot be dialed and must be called through the operator. Now, there are a few places like this in almost every state or province, but in general we can dial direct wherever we want. In Nevada and Yukon, in general we *cannot* dial a large number of small localities. I think in editing the Area Code Directory, for lack of space to list every single last point, the rule of thumb was if almost everywhere is dialable, and there is one area code only, then note 'all points, area such and such'.

TSPS was designed with the intention that any or all positions so designated may have direct access to verification trunks. The No. 1 TSPS console has an illuminated non-locking "verification" key which has two possible lamp indications, steady and 120 IPM flash. The exact function of this verification key is software-defined by the TSPS operating program running on the Stored Program Control (SPC) No. 1, the TSPS processor. Therefore, the operator you reach when dialing "0" may well have the capability to perform busy line verification without requiring the services of any other operator. However, depending upon the particular central office having the number to be verified and the local TSPS serving area, a request for busy line verification may still require the services of another operator. Traditionally, most CO's have two busy line verification trunks to service the entire office. In a local DSA serving area, these verification trunks would typically be terminated on a No. 1 or No. 3 Toll Board (cord type) so that at least two positions have access to the trunks; generally, there was no verification multiple to all positions. In large cities, there was usually enough verification traffic to justify at least one operator for this purpose. In smaller DSA serving areas, operators having verification trunk access would perform other duties while not serving verification requests. In SxS CO's, the verification trunks would appear as incoming trunks which connected to a verification distributor. The verification distributor would perform the same function as a first and second selector to decode the thousands and hundreds digits of a four digit number. The verification distributor selected a connector group where the tens and units digits were dialed into a verification connector. A verification connector would provide a metallic connection to the tip & ring of the selected subscriber line; there was no ringing or busy-test function provided in a verification connector itself. A verification connector was in most cases identical to a test connector, as accessed by a local test desk in a repair service bureau. In some SxS CO's the verification and test distributor circuits were combined, while in other CO's there was a separate verification distributor and a separate test distributor. There were several variations in the method of accessing a verification trunk from the No. 1 or No. 3 Toll Board. In some cases there were TWO jacks for each verification trunk - one for dialing and one for speech - which required the use of two cords by the operator. In other cases only one jack was required for both dialing and speech. In either event, in the case of a SxS CO only the last four digits of the subscriber number would be dialed into the verification jack. In the case of a crossbar CO, the last four or five digits would be dialed, depending upon the size of the CO. Since verification trunks were also used to actually break into a connection for emergency situations, in the case of a No. 1 or No. 3 Toll Board there was usually no one-way bridging amplifier; the verification trunk circuit, if equipped with a repeater, was designed for normal two-way communication. Therefore, an operator who accessed a verification trunk had the capability of talking to the connected subscriber line merely by operating the "talk" key at the cord position. Furthermore, if a subscriber terminated a call while their number was accessed via a verification connector, the operator could usually ring their telephone by operating the cord position "ring forward" key (actually, the toll board ringing was repeated using a "test trunk ringing circuit" at the terminating CO). In a crossbar CO, verification trunks would terminate as an incoming trunk, with an incoming register being connected through an incoming register link frame to accept the proper number of digits. Upon completion of dialing into the incoming register, a completing marker equipped to handle "special features" (usually completing marker No. 0 or No 1) would connect the incoming trunk through an office test frame to a "no test" vertical in the subscriber line link frame, thereby making a metallic connection to tip & ring of the subscriber line. A situation similar to the above exists in an analog ESS office, such as No. 1 ESS, No. 2 ESS and No. 3 ESS, in that a metallic connection is made between the incoming verification trunk and the subscriber line. While no doubt similar to the above, I don't know exactly how verification is handled in a digital ESS office, such as the 5 ESS or Northern Telecom DMS-series, since there is no longer a metallic path between lines and trunks; digital ESS CO's appeared LONG after "my time in the field". :-) In a TSPS installation having direct verification capability from any position, the verification trunks as described above would now be terminated as an "operator service trunk" on the Trunk Link Network (TLN) side of the TSPS switch. Therefore, any TSPS console on the Position Link Network (PLN) side of the TSPS switch can access any verification trunk so described. As far as I know, in the original TSPS there was no means for access to verification trunks other than through a TSPS console on the PLN side of the same TSPS switch where the verification trunks were terminated. Both technical reasons and security concerns imposed this limitation. However, times have changed and resulted in a great effort toward "centralization of operator services. Therefore, it may now be possible for a centralized facility to access verification trunks in several TSPS serving areas. Whether such centralized verification access is accomplished using the TSPS RTA facility or by other means, I don't know. In general, implementing busy line verification was a low-priority function during TSPS installation; consequently, verification trunks - along with other special service functions - were often kept on a few cord-type toll board positions long after cutover to TSPS. So the point is, depending upon the local TSPS serving area, verification may or may not yet be available for direct use by the TSPS operator one reaches by dialing "0". It was not uncommon for say, outlying SxS CDO's to have their verification trunks remain on a manual toll board stuck somewhere in a corner of a TSPS facility to save the cost of providing TSPS-compatible verification trunks to these SxS CDO's - which were scheduled for upgrade to ESS, anyhow. An interesting development for busy line verification was introduced several years ago in the Bell System. WECO designed a special verification bridging amplifier which intentionally distorted speech using a simple frequency inversion technique. Therefore, during a "normal" verification request, the TSPS operator could discern the difference between speech and non-speech sounds without actually eavesdropping on a conversation. I am not certain exactly how these special amplifiers were implemented, but I believe that ANY TSPS position could verify but not eavesdrop or break in to the conversation, and only certain supervisory TSPS positions could bypass the special amplifier and break into the conversation. So, getting back to the original question, chances are the same operator you reached by dialing "0" performed the verification, all in a matter of seconds. It is also important to understand that the functions of TSPS are TOTALLY PROGRAMMABLE. The TSPS console is nothing more than lights, keys, digital displays and a 4-wire talk circuit with local sidetone; ALL of its operational characteristics are determined by software in the associated TSPS processor: the SPC No. 1, which uses either the 1-type or 3-type processor. Therefore, the manner in which busy line verification is handled has changed in the past, and no doubt may change in the future. One final point: while the local test desk facilities in a repair service bureau may also be used to "verify" a subscriber line, there is usually a rather clear distinction between this function and "operator" busy line verification. An operator who verifies a line is only trained and equipped to detect the presence or absence of speech on a line, and there is usually no presumption that absence of speech on a line so verified is an indication of trouble. By far, the most common cause of a busy line where speech is absent is a Receiver Off Hook (ROH) condition; therefore, a verification operator will usually NOT refer a line to repair service, since to do so will burden a repair service bureau with a number of false trouble reports. Also, there is a type of apparatus associated with a repair service bureau known as a Line Status Verifier (LSV). The LSV should not be confused with apparatus or facilities intended for "busy line verification". The LSV is a cordless test position for use by repair clerks in handling trouble reports. The LSV provides very simply tests for line open, foreign EMF, etc. and displays obvious faults as a code number on a digital display. The LSV is NOT intended for busy line verification purposes, and is NOT found at any DSA/TSPS facility. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: David Albert Subject: Charging Telephone Solicitors (was Re: Annoying phone calls) Date: 1 Oct 89 13:31:34 GMT Reply-To: David Albert Organization: Aiken Computation Lab Harvard, Cambridge, MA In article <1627@l.cc.purdue.edu> cik@l.cc.purdue.edu (Herman Rubin) writes: >But the real problem is solicitation.... > >The only solution that has any chance of working is to make solicitors >pay you for soliciting you.

On the old We used to have this problem at home. My father had a home office, with a separate line installed, and they could never tell whether it was the home or the office phone that was ringing. I managed to solve this problem for them, totally by accident. I was rummaging through a bin of reduced-price clearance items in a Montgomery Ward store once, and found this little device which stifled your phone's normal ring, and instead played one of up to 8 user-selectable tunes. I can't remember all the tunes, but I know it included La Cucaracha, Yellow Rose of Texas, and Jingle Bells. Only a bar or two of the selected song would play. My mother used to change the tune every month or so when she got tired of the current one. Also, the dog used to get pretty excited whenever the phone rang. The unit ran on a 9-volt battery, which usually lasted a year or so. The best part was that it only cost me like $7.88 or so, since it was on clearance.

Just after these "improved" AT&T phones went on the market (1985), I was still able to find an unused Western Electric-labelled electromechanical white Trimline desk phone in among the new AT&T phones without too much trouble. In 1987, I wanted a matching (unused) wall phone, and only found one after considerable scrounging through stocks of low-volume AT&T resellers - I found one at a K-mart. In both cases, there was little packaging difference, and the prices were the same. I doubt if I could find any unused electromechanical Western Electric phones now (although someone pointed out in an earlier message that ITT and others are still making them). Interestingly, when I was looking for the phone in 1987, a salesperson told me that I should get the electronic model, since they offered a 3-year warranty on the new ones and only a 1-year warranty on the "old" (but unused) phones. I had my doubts that the new phones would make it through the warranty period, while I suspected that the old ones could outlive me.... There's a big difference between making a phone that you plan to maintain forever at your own expense and making a phone for retail sale! Even the AT&T Phone Center Stores won't lease the new phones, only refurbished old ones (but they refuse to sell them).

AT&T offers this feature on Merlin(tm) multi-button sets, allowing the user to program multiple cadence and frequency sequences. Anything from a simple RING to an elaborate DOOOOWEEEPDEDEDAH can be programmed from the keyboard. On mechanical ringers (in 500 or 2500 equipment) two rings can be made by swapping the left gong in one tel set with the right gong in the other. I'm not sure about other AT&T product families.

Our ATT System-25 at work doesn't have call forwarding, it has what we've come to refer to as call following. To trnasfer your calls to another phone, you have to go to that phone (known in the S25 manual as a "voice terminal") and do some magic there. To cancel the feature, you have to also do some magic at the remote phone. It works, but it's the reverse of the way people have been trained to think.

I don't know if this is true everywhere, but in New Jersey, the Caller*Id-equipped recipient of a forwarded call gets the caller's number, not the forwarder's number. If the caller is "Out of Area" then that is displayed; even if the forwarder is not. I tried to take advantage of this a few weeks ago. Our modems kept getting calls from somone/something that would disconnect after listening to our answer tone for several seconds. These calls always arrived two at a time, followed by two more about 30 minutes later. I waited until the first of a series of two arrived, and then forwarded the modem line to our Caller*Id-equipped voice line. But alas, when the second call arrived, the display showed "Out of Area" (even though the forwarding was intra-office) so I still couldn't identify the caller. But it didn't sound like a person or an open mic when I answered the voice line. Dave Levenson Voice: (201) 647 0900 Westmark, Inc.

During the 1970's there was a particular problem with thefts of telephone cable in the southwestern U.S., especially Arizona, New Mexico and Texas. The target was aerial lead-sheathed toll cable in remote areas of these states. AT&T Long Lines was a particular victim. The modus operandi was for the perpetrators, under cover of darkness, to first cut the suspension strands and remove the lashing wire from a mile or so of cable, allowing the cable to drop to the ground. This portion of the act, being the most time-consuming, did not break electrical continuity and therefore set off any carrier loss-of-pilot alarms. The next step was to cut one end, and then begin cutting the cable into lengths to be loaded into a truck. With several perpetrators, a mile of cable could be cut up and loaded onto a truck LONG BEFORE anyone could localize the fault and dispatch a repair crew. I can just imagine the expression on the faces of a Long Lines crew when they find a mile or so of cable has simply *vanished*! The profit from this enterprise was tempting. A typical lead sheath toll cable, like a type S-54 27-pr 19 AWG, yields about 1/2 pound of copper and 2 pounds of lead per lineal foot. Using late 1970's prices, a 5,000 ft section of cable would yield around 2,500 pounds of copper and 10,000 pounds of lead, with a total metal scrap price of at least $ 3,500.00. Not bad for an evening's work with little risk of apprehension. The combination of some arrests, burying of cable, and declining lead and copper prices caused this activity to diminish, although the problem does reappear from time to time. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Tue, 3 Oct 89 0:13:01 CDT From: TELECOM Moderator Subject: Usenet Gateway Acting Funny It has come to my attention from a few people that the Usenet gateway to 'comp.dcom.telecom' has been acting funny for a few days; or to be more precise, nothing has been moving through there since around September 28. It may not be the gateway, but some machine in the middle somewhere. I've sent a note to Chip Rosenthal asking for advice on this. Ordinarily the gateway sends an automatic receipt to me as notification when an issue of the Digest is processed. I received no notices over the weekend, and today a few people said the group was pretty barren of new stuff since last Friday. I assume we will get reconnected eventually, and the poor Usenet people will get 60-100 messages all at once!

[....] Actually, this tone (continuous rising for 1 second, continuous falling for 1 second, etc.) is still in use by C&P Telephone on the 301-867 exchange (West River, MD), for misdialed outgoing calls (e.g., dialing a 7-digit number for an exchange not in the local calling area). Calls to a non-working 867-xxxx, however, get routed to an AIC and get an intercept recording! I haven't tried dialing a 1+ call to a non-existent area code; I guess that would tell me if the local switch knows area codes or passes the 1+ call to a smarter tandem. This switch is being replaced by "the most modern electronic switching facility in Maryland" this Fall; can anyone tell from the use of the not-a-number tone what kind of switch I'm on? It's definitely not a stepper: touch-tone calls complete in milliseconds. No "custom calling features" are available; neither is Centrex, or Equal Access. Per-call and timed local billing is available. My guess is a #5 crossbar; reasonable?

At first there seems to be no pattern to the way the letters are assigned, but if you arrange them according to the number of bits that are set in each character, it becomes clear. The most common letters of the English alphabet (ETAIONSHRDL....) and the word separators (space, return, line feed) have the codes with the fewest number of marking bits. Question 1.

It is a file... This is antisocial behavior of the worst kind! Blowing UNCOMPRESSED data across the network only to compress it on your end and then have to uncompress it again to read it will do two things: 1) It will eat a bit of CPU time on your machine. If you're on a single user workstation, then you aren't taking anyone else's cycles and that's fine. But if you are on a general-use timesharing system (like your organization's main VAX or something like that), you're bogging down system response for other users. 2) YOU ARE SENDING A LARGE AMOUNT OF UNCOMPRESSED DATA OVER A PUBLIC NETWORK. This will have detrimental effects on others who are using the network for telnets and FTPs. The explosive growth of the Internet over the past several years has made it well neigh impossible for the people who run NSFnet and the regionals to keep up with demand for network bandwidth. Don't make matters worse by capriciously moving large amounts of data over the Internet without compressing it first. There is no inherent benefit to sending a large file by telnet over sending it via FTP. I urge whoever is making this list available to the public to COMPRESS it, make it available for FTP, and have a mailbox set up so that people can send their information if they want to be included. I urge readers of TELECOM to NOT retrieve this file until it can be retrieved in a matter that is more considerate of others. ---R.E.

Evidently, as of late last week, 93% of the island's residents had telephone (the remaining 7% being primarily in the eastern portion of the island that took a direct hit). As I mentioned in my previous post on this issue, I was able to get through via AT&T, but not MCI. AT&T does, indeed, provide the bulk of the transmission service to Puerto Rico (although exact figures weren't given). I recall reading, by the way, that PRTC is going to convert to equal access next year sometime. AT&T normally has 6500 circuits to PR, 4000 via satellite, and the remaining via microwave to St. Thomas and then via cable to the US. The 2500 ckts to St. Thomas are still out due to the widespread destruction there, but the satellite links were back in operation as soon as the winds were mild enough to permit the antennas to be set up again (by 10:30pm Sunday, according to the article).

Over about 8 years that we had it, the thing got tossed around, was dropped more times than I care to mention, and it never developed one problem. Were you to take an AT&T 2500 set manufactured today, I doubt it would survive even one fall to a hard floor. Interesting, isn't it, how even AT&T builds phones differently when they know that they won't be maintaining them forevermore. Frequently, you can go into some back-roads store and see a 500 set that's been working fine since the '50's. I dare say that in 30 years it will STILL be working fine after all the phones manufactured today are long gone. Gabe Wiener - Columbia Univ.

I thought that, when Area Codes were 'invented' in 1946 (not 'implemented,' just 'invented'), the system was as follows: - States small enough to require only one area code got a zero as the center digit, with the other digits depending on population density or urbanization (higher numbers to more rural states). The most urban, New Jersey, got the lowest number of this series, 201. DC got 202. - States big enough to require more than one area code at the outset got all codes with a 1 as the center digit. The outer digits were assigned in the same general way as described above. New York got 212, the second and third most populous cities got 213 and 312, other big cities got 214, 412, 215, etc. If this is indeed true, then ANY state which currently has more than one area code AND has at least one area code with a 0 as the center digit, must, by definition have been split at some time. Perhaps the split happened only 'on paper' before DDD was widely available. Perhaps it just occurred a long time ago. Here's a list of the affected states which obviously had only one code (with a zero in it, still serving the major city) at one time: Florida 305 (813, 904 and 407 all added later) Louisiana 504 (318 added later) Nebraska 402 (308 added) Washington 206 (509) Oklahoma 405 (918) Kentucky 502 (606) Tennessee 901 (615) Georgia 404 (912) New Jersey 201 (609) North Carolina 704 (919) Virginia 703 (804) Here's a list of states which probably always had more than one code (all of them with a 1 in the middle), which have added codes with zeros in them since: California (added 209, 408, 805, 707) Illinois (added 309) Texas (added 806, 409, soon 903) Minnesota (added 507) Massacusestts (added 508) New York (added 607) Some of these states have also added codes with 1's in them in addition to the zero codes mentioned above. For example, New York has added 718. That doesn't cloud the picture. Additional ammunition: telephone directories in New Jersey have listings in them of every prefix in the state, grouped by area code. (Wish every state did this.) In each list, a mark referring you to a footnote appears next to any central office code which is duplicated in both 201 and 609 areas. Why? Allow me to speculate: Because at one time New Jersey must have had only one area code with no prefix duplications. 609 was added early on with the knowledge that the state would outgrow 201 before DDD was widely implemented. Even though the state now had two area codes, there were still no prefix duplications and it was likely that 7-digit dialing applied statewide. (To my knowledge, New Jersey *never* had 1 + 7 digit dialing for intra-NPA toll calls.) Eventually, as the concept of area codes caught on, New Jerseyites were required to dial 10 digits to reach people in the 'other' area of their state. (This does not apply universally in NJ, however. There is some code conservation with 7 digit calls across the border allowed.) Is there anything wrong with this reasoning or the history about the zero and one codes that makes this wrong? Does anyone remember the above states splitting when they were knee-high to a grasshopper?

Hoffman" Date: Tue, 3 Oct 89 14:15:32 EDT Subject: WRGB and Telephones, 1936 style Recently, someone suggested that the TV station WRGB (Schenectady, NY) was named after "Roy G. Biv." This is incorrect. (The station predates color TV, by the way: it was founded on January 13, 1928.) The station's call letters were derived from one of the founding executives, Walter R.G. Baker. I realize this has nothing to do with telecom issues, so I'm including the following, excerpted from _The_Poestscript_, the newsletter of the Poestenkill, NY Historical Society, September 1989. (Copied with permission of the editor. Typos are almost certainly mine.) For the curious, Poestenkill is a small town just outside of Troy. Telephones -- 1936 Style More than 50 years ago, the idea of a telephone strike in Poestenkill would have been out of the question. Not that there weren't telephones here, but they were run on a cooperative basis by the telephone customers. I believe there were two lines -- the "one-eight-F" and the "one-seven-F." A small book of meeting minutes covering the period April 22, 1936, to April 4, 1938, seems to indicate that there were about 11 families on the 18F line... Those present at that April 22 meeting voted to purchase "#12 gage [sic] wire, glasses and what ever needed... Motion made & Sec. that each member be assessed $10.00 to pay for new wire and material. Motion made ... to leave the officers as they are till line is completed." The outstanding assessment of one member of the group reached $18.91! On March 9, 1938, they voted that if payment was not made by March 31, 1938, that member's service would be discontinued and "an action for collection will be taken by 18F Telephone Company." On April 5, 1938, they accepted a $10 payment from the delinquent and granted him further time. They maintained their own lines. At the April 8, 1937, meeting, a "motion made by Vernon Hoffman that every man on line be on hand on Monday morning next April 12 or hire a man to take his place." Trouble with noise on the line prompted a July 2, 1937, vote to appoint a committee of two to find a telephone mechanic "to service our line at the best price" with the committee to report at the next meeting. Each member was to pay for service on his own phone from the pole to the house. On July 12, 1937, they voted to hire Mr. Listen [!] to put the line in shape. To place a call off the line, one long crank got you the operator. To call on the line to reach 18F31, for example, three longs and one short would be used. [One member] told us at a meeting some time ago that his family was one of the few in his area to have a phone, and they used to leave the downstairs door unlocked at night so the neighbors could get in to use it. It was probably the late 40's when the AShley exchange came to town, and not too many years after that the operator disappeared from our life as we got dial service. Kelly K.

Two cop cars pull up to the Data Center, and said that they received quite a few 911 emergency calls that were traced to our address. Well it turns out that the phone number making the calls is our 2400 baud Public Network access number. One of the cops queried, "How do I write a summons to a computer?". It made me think, if thats as far as the 911 people can trace a call, and say our Network Control cannot trace it back to whoever originated it, how would 911 put a cap on computer pranksters?

Fremont, CA Roy Smith (roy@alanine.phri.nyu.edu) mentioned that vandals were stealing copper cables from Metro North (Amtrak). This is the only instance of this happening. In a more telephone related instance, copper wires providing telephone service to remote parts of California have been stolen. The following excerpts come from a reprinting of a Los Angeles Times article that appeared around Sept. 23. International jewel thieves they are not. But pesky bands of burglars have caused a heap of trouble for a string of remote desert towns this summer, stealing miles of the copper telephone wires that link the outposts with the rest of the world. Lured by the high price of copper, thieves have stolen about 55 miles of multi-strand bare wire in San Bernardino Co. and another 80 miles in Riverside Co. The unusual burglaries there have left homes and businesses in the towns of Ludlow, Amboy, Cadiz and Danby without phone service periodically since early August with some residents cut off for as long as a month. Residents of Amboy had to drive 50 miles to Twentynine Palms to make telephone calls. Becuase of the troubles, Pacbell has decide to link the areas phones to a microwave system. Until the install is completed in November, the affected towns will be on an emergency radio system. David A.

Subject: Re: Phone Design Date: 30 Sep 89 22:35:33 GMT Re: Phone Design I first made the switch from mechanical ringer to electronic warble about 5 years ago when I moved to Canada. The warble comes out of a cheap speaker, and it's impossible to tell what direction it's coming from. As a result, whenever a warble phone rang on the TV, I jumped from my chair. I never completely got over that. On the bright side, the Harmony (tm) and Signature (tm) phones I had from Northern Telecom were some of the best of the new generation phones I've seen. A `shoulderable' receiver, a nice handle for carrying the phone around while you talk, and up to date styling were all welcome. They were rugged too, though I almost did one in with a glass of vermouth into the keypad. A good rinsing of the insides fixed it. Those two models weren't for sale, or I'd have one here. I haven't found anything else that I thought looked as nice and worked as well. Fortunately I found an old 2500 recently, and don't miss the NT phones so much any more. And does anyone besides me have fond memories of the Panel Phone (tm) ? My parents still have the two we had installed about 20 years ago, and they work fine. They were installed into the wall, requiring a hole about 8 x 10 inches, and have a non-tangling cord about 4 feet long which retracts into a hole in the panel. They've never failed, despite the thousands of times my father said I was pulling too hard on the cord. They'll never go modular, I'm afraid, and if they do fail, we'll have to call the plasterer, but they made a lot of sense. We even have one of those two-line knobs on one of them, though it's not hooked up to both lines any more. An installer who came by the house a couple of years ago had never seen them before.

I have a menu item called "Dial!". When I click it I get a prompt "Number please". I can then type in the number or use any of the system's line editing features. For example, I can shift-select the number out of another window instead of having to type it at all. If I click on Dial! with the middle button, I get a menu of the last 10 numbers I called, if I want to redial one. One nice feature is that the program automatically translates letters into numbers. I hate dialing numbers like "GO-AMIGO" on the phone, but it's real easy to type this on a computer keyboard. The program also knows how to add the leading "9" for local calls, and "8" for long distance. This all works well since my computer is running all day anyway - might as well let it do the phone too. While we're at it, I might as well throw in my teletype reminiscences, since everyone else has. In 1967 I belonged to the Weather Club in our high school. We had two teletypes with direct lines to the local Weather Bureau (this was before it was the National Weather Service). One line was called "Circuit A", which sent data from the northeast U.S., and the other was "Circuit C" which was national (I think circuit B was the south-east). I don't know the model numbers, but they were old even then. They were the kind that had the type in a rectangular box. The machine would move the box vertically and horizontally to position the proper slug under the print hammer. It was indeed, as someone else mentioned, fascinating to watch. Anyway, our machines were receive-only; they had just two buttons in front. One was labeled "LOC LF" (local line-feed) - I forget what the other was. My job was to get there at 7 AM to plot the national weather map coming in on circuit C. Each station sent its data in a single line of text (all numeric). There were several hundred stations reporting. After a few months of this I got good enough that I could plot faster than the tty could send. Being an impatient sort, I discovered that if you hit LOCLF *exactly* at the end of a line, you could eject enough paper while the carriage was returning so that you could tear off a little strip with just that one line before the next line started printing. People would get mad at me because by the end of the transmission, the report, which usually filled half a dozen pages, looked like it had been through a paper shredder. Sometimes the fuse that controlled the carriage would blow. This was apparently separate from the print hammer. If this happened at night, you'd come in the next day to find the entire report banged into a single character position. All that was left of it was a ragged hole in the paper. Sometimes people would forget to power up the motor on the take-up reel when they left in the afternoon. Then we'd come in the next morning to find mountains of yellow paper piled all over the room. Occasionally, the machine would drop a character. Since the reports were all numeric in fixed-length fields, a missing character would lead to some interesting weather reports. You could always tell a novice had been plotting the map when you found a station in Canada reporting 90 degrees in mid-January, or showers of ice needles in Miami. I suppose that's all gone today. Nowadays, the maps are plotted by computer and faxed to local Weather Service offices. But I'm sure this can't compare to the thrill of racing circuit C, man versus machine, in the pre-dawn darkness of another era. - Michel ------------------------------ End of TELECOM Digest V9 #427 *****************************   Date: Wed, 4 Oct 89 1:40:00 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest V9 #428 Message-ID: <8910040140.aa22235@delta.eecs.nwu.edu> TELECOM Digest Wed, 4 Oct 89 01:35:11 CDT Volume 9 : Issue 428 Today's Topics: Moderator: Patrick Townson Price Competition in Japan on International Calls (David Gast) Re: Locatable Ringers (Kent Borg) Re: Australian Broadcast Call Signs (Dave Horsfall) Re: Prefix '520' for Los Angeles Radio Stations (Dave Clements) Re: California Junk Fax Bill (John Higdon) Re: ANI Updates Wanted (Thomas E.

Judice) ---------------------------------------------------------------------- Date: Tue, 3 Oct 89 22:25:24 -0700 From: David Gast Subject: Price Competition in Japan on International Calls On October 1, 1989, KDD (Kokusai Denshin Denwa-- International Telegraph Telephone), the only organization that had been able to carry international telephone and telegraph communication since the end of WWII lost its monopoly. Two new firms entered the market: International Telecom Japan, Inc. and International Digital Communications. KDD had revenue of $1.95 billion last year, but the new competitors are undercutting its prices by more than 23%. The president of KDD is quoted as saying "We've never faced any competition before, ... it is quite a shock." The new rates will make calls from Japan up to 20% cheaper than calls from the U.S. using the dominant U.S. carrier, according to the NYT. (At least one LDC, however, however, offers significantly cheaper calls than the prominent U.S. carrier). The new arrangement also shows major differences from U.S. practice. In the first place, the new companies are not startups. International Telecom's shareholders include Mitsubishi, Sumitomo, Mitsui, Marubeni, the Bank of Tokyo, Matsushita Electric (Panasonic), Tokyo Electric (the Commonwealth Edison of Tokyo). International Digital's shareholders include C. Itoh (a trading company, but also the maker of computer terminals, the trading company involved in the Toshiba scandal of a few years ago, etc), Toyota, Cable and Wireless of Britain and PacBell. C&W had been previously been involved in a major dispute with respect to the extent that it could participate. Pacific Telesis's participation lends credence to John Higdon's contention expressed in a previous article that PacBell is attempting to become the old Bell System. This arrangement should also raise eyebrows among those who believe that foreign investment in Japan is impossible. How many Japanese companies do you know that own American telecommunication industries? (Of course, this this arrangement may change). The equity contribution by these major players indicates that the new companies are not likely to fold soon. The second difference is that Japan decided to avoid the expensive advertising campaigns prevalent in the U.S. The new startups will not have to spend millions advertising on T.V. to get consumers to sign up as "dial 1 carriers." Every phone in Japan (although contrary to published reports, I suspect that certain coin phones are excluded) is automatically connected to the new phone companies. Consumers only have to prefix their international calls with a unique three digit code to get the international telephone company of their choice. KDD used to require prior agreements to make direct dial calls, but presumably the new phone companies do not. Note: Because KDD was separate entity from NTT, Japanese consumers always had to dial a three digit code to get KDD. Even with monopoly status, rates for KDD's international phone calls have declined drastically in recent years. 10 years ago a 3 minute prime time call cost $15.00. Now KDD's prime rate is $6.35. (It is unclear from published reports whether the reductions take into account the dramatic fall in the dollar vis a vis the yen. If it does not, the rate reduction from a Japanese perspective has been more substantial). The new companies will charge $3.00 to $4.85 for a three minute call, substantially less than AT&T on calls from the U.S. to Japan or for U.S.A. Direct calls from Japan. AT&T charges $3.78 to $6.02 for direct dial calls from the U.S. to the Japan. From a technical standpoint the new companies are expected to offer superior quality as these calls are more likely to go through fiber optic cables across the Pacific instead of satellites. On the other hand the new carriers will only be going to popular destinations like the U.S. David Gast gast@cs.ucla.edu {uunet,ucbvax,rutgers}!{ucla-cs,cs.ucla.edu}!gast ------------------------------ From: Kent Borg Subject: Re: Locatable Ringers Date: 2 Oct 89 23:01:18 GMT Reply-To: Kent Borg Organization: Camex, Inc., Boston, Mass USA In article Kenneth_R_Jongsma@cup. portal.com writes: >With the traditional bell, it is possible to be in any one else's >office and tell if your phone is ringing based on the volume and >direction of the bell.

System-25 does it that way because Horizon(tm) did it that way. That, in fact, explains most of the System-25 feature set. No, I don't know exactly why Horizon did it that way, but it may be related to their "floating phone number" feature. You can have phone numbers in your Horizon or System 25 which do not correspond to real telephone sets (or voice terminals, for that matter!). If you are a fast-mover around your office, you may be without a physical set, but you can have a floating extension (called a PDC or personal dial code, in System-25 speak). You can then "log in" your floating PDC at the nearest real telephone set, and receive your calls there, until you log out or log in at some other voice terminal. Call-following is just a special case of logging in a PDC (but in this case, not a floating PDC) on a voice terminal.

CORDLESS TELEPHONES--A new generation of cordless telephones is appearing in Europe, which are being called "the poor man's mobile telephone". At the same time, the current cordless phones in Sweden cost more than cellular telephones in many other countries. Cordless telephones have become popular all over the Western World and the Far East. The exception is Sweden, where cordless telephones remain too expensive for ordinary households. In fact, Swedish cordless telephones cost more than the mobile or cellular telephones used in automobiles in other countries. This is because Sweden uses a unique frequency band for its cordless phones. The kind found in the rest of the world use frequencies around 49 MHz. This band is, however, still used by television in Sweden. Two transmitters for Swedish Channel 1 use frequencies close to 49 MHz. Rather than move those two transmitters, Swedish Telecom has decided that cordless phones in this country shuld use the exotic frequencies of 914 and 959 MHz. Because of this, the legal cordless phones sold in Sweden cost as much as 10 times what similar units cost abroad. Consequently, many Swedes buy cordless phones in other countries and try to smuggle them past Customs. So far this year Swedish Customs has confiscated 1500 to 2000 cordless telephones. That's roughly twice as many as during all of last year. Now Britain has begun testing the next generation of cordless phones, called CT-2. This operates at 864 MHz, using special digital signals. When you use CT-2, you carry the handset in your pocket, and around town there are relay stations called phonepoints, instead of traditional phone booths. The idea is that you can call out from anywhere within range of a phonepoint, although you can't receive calls. That's why the system is being called the poor man's mobile telephone. The pilot service has only 100 users and 30 phonepoints, all in London. The service is expected to cover all of London by the end of this month, and 1000 phonepoints are to be installed during the first year. When Britain is fully wired, there will be 16,000 phonepoints. The British decision is controversial, because European standards have yet to be decided. Britain hopes to sell its CT-2 system to the rest of Euyrope, so that the same pocket telephone can be used anywhere in the continent. It now looks as thought the French have accepted the British system, for their "Pointel" public cordless network. Happily for Swedes, Swedish Telecom has indicated it will adhere to the forthcoming international standard for CT-2.

One article quoted a guy who claimed that he stood there helpless while the machine churned out junk fax, when he needed to send an important document. Somehow it never occured to him or the writed xxxx writer of the article to just unplug the RJ11 for a few seconds or hit the STOP button so that he could send his fax.

PT] ---------------------------------------------------------------------- Subject: Possible California PUC Changes -- L.A. Times Story Date: Wed, 04 Oct 89 16:16:46 PDT From: nomdenet@venera.isi.edu The story below is from the Los Angeles Times of October 1, 1989, in the Business Section (part IV), p. 1. Reprinted without permission. Rewriting the Book on Phone Rates by Bruce Keppel Times Staff Writer (San Francisco) Charlotte Ford's cubbyhole of an office hardly looks like a place where history is being written. But it is there, nonetheless, that the 36-year-old administrative law judge distilled, from thousands of pages of sometimes gnarly testimony, what may be the most far-reaching regulatory proposal every made by the California Public Utilities Commission. What Ford has wrought on behalf of her bosses -- the five utilities commissioners appointed by Gov. George Deukmejian -- is a 361-page blueprint to overhaul regulation of the state's two biggest local phone companies, Pacific Bell and GTE California. One virtually certain result of this proposal, expected to be approved Oct. 12 after some final tinkering by the commissioners, will be lower basic phone rates next year. Another will be freedom for the companies to shoot for higher profits and to enjoy unprecedented, if limited, latitude in setting prices for optional telephone services. The long-term payoff, if the system works as Ford conceived it, will be a streamlined regulatory process that liberates the phone companies to pursue technological advances that benefit the economy and hold down prices for phone customers. And although many consumer advocates are doubtful that those goals will be realized, the PUC's push in telecommunications is expected to foreshow a fundamental change in the way that the agency deals with energy utilities, freight haulers and the other businesses that it regulates. "There has to be streamlined processing," said Commissioner John B. Ohanian. "I envision the commission getting away from the 'micromanagement' of these companies. Instead, let's modernize the way we regulate and synchronize it with the pace of change in the business world." At the top of the PUC's agenda is phone regulation. A number of other states have similarly re-examined traditional phone regulation but, with the possible exception of Vermont, California is proposing the most comprehensive overhaul. Simplified Process With the new plan, gone will be the close surveillance of management decisions made by Pacific Bell and GTE California -- a prospect that delights both companies. Traditional rate-making procedures now require the PUC to determine utility costs, a process that requires poring over corporate books and second-guessing management decisions to arrive at the amount of annual revenue that the company will need to break even. The commission then adds to that sum a maximum profit for the companies to shoot for but not exceed and finally sets phone rates accordingly. The Ford plan would authorize the PUC to continue setting prices for basic telephone service, although it would simplify the way that is done. It also would: - Cap prices for such optional "enhanced services" as call forwarding and let the companies lower charges if they wish, perhaps to increase sales volume. - Deregulate prices for the present handful of competitive services, such as yellow pages advertising and, perhaps, maintenance of phone wires in businesses and homes. - Replace commission-imposed penalties for unnecessary investments and excessive costs with financial incentives to reward efficiency. To make this more flexible pricing system work with a minimum of state intrusion, Ford created the most elaborate system so far of "checks and balances" designed to protect shareholders and customers alike. Yet, in California as in the other states tinkering with regulatory reform, only the telecommunications investors and the companies involved seem to support the changes. Many customers -- including giant long-distance carriers such as American Telephone & Telegraph and MCI, which depend on local phone companies to complete their calls -- worry that loosened regulation will mean service headaches. Ironically, AT&T recently was granted greater pricing flexibility in its long-distance operations by both state and federal regulators. For the first year under the new regulatory setup, the PUC will lower phone rates because both Pacific Bell and GTE California have exceeded their currently authorized profit ceilings. Productivity Factor After that, and on Jan. 1 of every year from now on, the companies' anticipated revenue figure will be adjusted for inflation, minus an assumed reduction in operating costs due to belt tightening and labor-saving technology. Ford proposed what it {sic} calls a 4% "productivity factor." Thus, if inflation boosted costs generally by 5%, only a 1% increase would be passed on to telephone customers. "This productivity target will challenge [the phone companies] to be at least 4% more efficient in their operations than is the economy as a whole," she maintained. A key question that the five commissioners must decide Oct. 12 is whether Ford's 4% productivity factor is reasonable. The companies argue that 4% is too ambitions, while the consumer lobby known as TURN (for Toward Utility Rate Normalization) says it should be more like 7%. Moreover, TURN considers Ford's proposal to be "overwhelmingly skewed in the utilities' favor," said executive director Audrie Krause, a former Fresno Bee newspaper reporter who assumed her TURN job last summer. Under traditional regulation, Krause pointed out, the PUC limited company profits, or rate of return, and required any excess earnings to be refunded. The maximum profit margin for Pacific Bell currently is 11.34% and 11.13% for GTE California. Because a basic principle of Ford's plan is to strengthen the profit motive, she set a target rate of return, based on her estimate of current market conditions, of 11.75% for 1990. But she would let the companies keep all earnings up to 12.75% to motivate them to perform well, then would allow them to keep half of any additional earnings up to a maximum of 16.75% TURN considers each of these benchmarks, especially the 16.75% maximum return, to be far too generous, and it also urged that if the commission allows any profit sharing, consumers should get 60% of the earnings involved, not 50% as Ford suggested. In contrast to TURN's strong opposition, PUC President G. Mitchell Wilk, who has worked closely with Ford as the commissioner responsible for the case, hailed Ford's framework as "a win-win situation" for customers and investors. "It needs to be improved in some areas, filling in some gaps and doing more balancing," Wilk said, but he defended the 4% productivity factor as "a real stretch" for Pacific Bell and GTE California. He termed TURN's opposition shortsighted, saying the 1984 breakup of the Bell System and rapid technological changes have made reform inevitable and probably overdue. "Divestiture changed the regulatory framework for this industry," Wilk said. "We can't put our head in the sand and pretend we're dealing with Ma Bell. Carl Danner, Wilk's telecommunications adviser, said Ford's framework creates necessary new incentives to reward efficiency and get telephone employees "thinking the way we want them to think" instead of trying to "put one over" on regulators by padding costs to boost revenue. "Our economy runs on these incentives," said Danner, who holds a doctorate in public policy from Harvard University's Kennedy School of Government. "To the degree that the phone companies are losing their monopoly status, their world should begin to look more like that [of the the competitive economy]. It's becoming untenable to do the other form of regulation." Terry L. Moore, who heads a PUC division representing utility customers, agreed with TURN, however, that some of Ford's profit targets are too generous and that the productivity factor is too low. Still, Moore added that she is "in general comfortable with the framework" that Ford devised. "The key is getting [rates] right at the start." William R. Ahern, a former RAND Corp. analyst who now is PUC director of strategic planning, said Ford's framework also makes it far more difficult for the phone companies to unfairly subsidize their competitive ventures with profits from the basic phone business. If successful on that score, Ford's plan would resolve a lot of complaints already made by would-be competitors in such areas as voice-mail services, privately owned pay phones and telephone wiring repairs. Commissioner Frederick R. Duda called the impending commission decision "clearly historical" and one not to be confused with deregulation. "This is not deregulation and it's not traditional regulation," he said. "It's a compromise. And the question is whether it will work and for how long. "Marketplace reality has caught up with the system," Duda said. Duda -- along with commissioners Ohanian, Wilk, Stanley W. Hulett and Patricia M. Eckert -- has reservations on a number of details, but all five seemed, in separate interviews last month, to be generally pleased with the comprehensive plan. For Ford, the telephone case represents by far the most complex that she has handled. The Mississippi native, who holds a bachelor's degree in mathematics and a master's degree in electrical engineering, said her aim was to devise a framework that would work adequately even when some of the forecases for the telephone business are off the mark. "We can be fooled by forecasts," Ford said recently as she sat in her tiny office surrounded by volumes of hearing testimony and a stack of comments on her framework. She said she tried to create "checks and balances" within the framework to contain excessive earnings -- or losses if the bottom falls out of the market -- within reasonable limits. That approach is also demonstrated, she said, by the way in which implementation will give customers the first benefit in the form of an immediate rate cut, in inflation-adjusted dollars, while shareholders will get theirs later in the form of higher profits if their company performs well. In any case, she added, the commission will reassess the new system in 1992. Investment analysts generally warm to any attempt to allow market forces to work within a regulated environment -- and especially to shift from cost-based regulation to pricing regulation because of the potential for higher earnings. Even so, Robert B. Morris III of Goldman, Sachs & Co. foresees some potential problems for both telephone customers and the companies themselves. "It's a break from historical regulation," Morris acknowledged, "but to me it doesn't appear that the commission has handed them they keys to the kingdom." Moreover, he added, there may be a drawback for consumers. By dividing telephone offerings between tightly regulated basic telephone service and flexibly priced enhanced telecommunications services, Morris said, the new regulatory framework may interfere with the smooth flow of new technology throughout California. In other words, Morris said, some markets outside major metropolitan areas might not get certain advanced services unless regulators require them to. "Only markets that can pay for them will get the services," Morris predicted. To Ford, criticism and controversy come with the territory. "No one's going to entirely like what you do," she said. "And if someone does," she added, "it makes you wonder if you've done the job." Sidebar: Incentive-Based Rate Plan Takes Phased Approach --------------------------------------------------------- The California Public Utilities Commission is expected this month to adopt an incentive-based system for regulating Pacific Bell and GTE California. As proposed, effective Jan. 1, the system would: - Cut phone rates next year and then peg them in future years to a cost- adjusted formula. This formula would limit price increases to the rate of overall inflation minus 4% for assumed efficiencies due to cost cutting and labor-saving technology. Thus, in a year in which the cost of living increased 5%, telephone prices should rise no more than 1%. If inflation rose less than 4%, phone prices would actually be cut. - Reorganize regulation so that the PUC still would set rates for basic phone service, which on the local level remains a monopoly. Prices for most optional calling features would be capped, but the companies would be allowed to lower charges, within limits, if they wished to encourage usage. Prices would be deregulated for such services as yellow pages advertising where competitive alternatives already exist. - Authorize the PUC, as part of its rate-setting procedure, to establish a target rate of return for the phone companies, the companies could keep all profits for another percentage point, but earnings in excess of 12.75% would be split evenly between customers and the company. Earnings exceeding a 16.75% return would be refunded. For phone customers, the refund would come as credits in future bills. In a final phase of the regulatory revision to be completed next year, the proposal calls for the commission to revise all telephone rates to reflect the new system. This "rate design" phase would eliminate the bewildering array of credits and surcharges applied to customers' bills. At that time, the proposal recommends that the PUC scrap a 20-year-old $1.20 monthly fee for "Touch tone" service and also expand the local service area in which unlimited calls can be made at no extra charge from 8 miles to 12 miles. ------------------------------ End of TELECOM Digest V9 #430 *****************************   Date: Thu, 5 Oct 89 20:42:00 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest Special: Eat Crow!

The messages excerpted below speak for themselves, I guess. There were some additional messages marked 'not for publication', and they are not included, but correspondents should be assured all have been read and considered. Regards the list which started this thread, if anyone wants it who cannot aquire it through the suggested instructions, they should write to me at 'ptownson@eecs.nwu.edu' -- NOT to the telecom address. I will send a compressed copy unless you specify you have no way to uncompress it on your end. If you prefer 'uuencode' and 'uudecode' instead, please specify that method. So here is the consensus -- ==================== From: jsol@bu-it.bu.edu I second the motion. What R. E. Seastrom doesn't realize is that the command "telnet foo 21" will do the same thing as "ftp foo". The connection that is used in a FTP command is not compressed nor is it load-reduced in any frame of mind. I want my FTP jobs to get done FAST, I don't want to background them just because some twit wants to play nethack on a machine across the country. This is more legitimate than playing games. Now, if the program could be offered compressed and uncompressed that would be useful. The host table is currently compresed, however the host port on the NIC.DDN.MIL machine that you can use (by telnet nic.ddn.mil ) to receive the host table is the same way and it is definitely official business. Saying that the Internet growth has to be slowed is a good idea, but you pointed your gun at the wrong issue. jsol ==================== From: Will Martin Well, anti-social or not, I've tried the given command from BOTH a Sys V system (Unisys) and a BSD system (VAX) and all I get as a response is: "telnet: connect: Connection timed out" However, I must say that it DOES seem rather strange that the original message quoted by the moderator says this: >If you don't have tail or compress, just redirect the telnet output >into a file. That indicates the file is coming in uncompressed mode. What is the purpose of them telling the requesters to feed it into compress and end up with a compressed file, anyway? To use it you would have to then uncompress it. That appears to be what Mr. Seastrom was pointing out. Am I missing something here? Regards, Will Martin ==================== From: Paul Fuqua The file does not travel compressed, it is compressed because you pipe it through compress on your end. Go telnet to 128.146.1.5, port 4666, without the piping stuff, and see what shows up on your screen. Since hpuxa does not provide anonymous FTP, I can see why they'd choose this somewhat weird method of distribution, but maybe they'd be better off talking to the CIS department -- osu-cis/tut.cis.ohio-state.edu provides both anonymous FTP and anonymous UUCP. Paul Fuqua pf@csc.ti.com {smu,texsun,cs.utexas.edu,rice}!ti-csl!pf Texas Instruments Computer Science Center PO Box 655474 MS 238, Dallas, Texas 75265 ==================== From: Doug Faunt N6TQS 415-688-8269 Err, Mr. Seastrom overreacted, but he's correct. Using the script given, the compression takes place at your machine, and the file is transmitted uncompressed. I suspect that Dan Bernstein has not got official approval of what he's doing, which is why the strange method of file transfer, and therefore an address at ohio-state, or nyu gives him no standing from that. Compressing the file before the transfer, and using anonymous FTP is the standard way of doing this type of file distribution. A server, for both mail and telnet requests, is another alternative. You over-reacted also, and as moderator, it's part of your job to cool flames, not fan them. respectfully, doug faunt ==================== From: Frank Prindle Patrick, One small correction - the list is transmitted via telnet (TCP/IP protocol) and is not transmitted as (and cannot be transmitted as) a compressed file, because telnet protocol supports only text transmissions. The suffix .Z does indicate a compressed file (not .z, but .Z), but the Unix command line given does the compression at the receiving end (for what purpose, I'm not sure, since it is not too much fun to search the file that way). Also, any claim that this is a nearly complete list of internet users is highly exaggerated. It appears to be a compendium of registered members of a small subset of Arpanet mailing lists, certainly not all, and extremely far from a complete list of users; NADC.arpa alone has over 1000 users capable of sending and receiving internet mail, and at least 100 active in one or more mailing lists; the subject list includes precisely 3 (curiously, I am one). Several substantially larger and more organized lists exist: one, a commercial venture called National E-Mail Registry includes all commercial E-Mail systems in addition to Arpanet/Milnet/UUCP/Bitnet/etc..... Another is the "whois" database maintained at SRI-NIC.arpa. Both of these allow voluntary free registration; the fact that they rely on individual manual registration means that they still each cover only a minor subset of the total population they are trying to list, but do list such things as address, phone number, etc. I realize that you were just relaying a bit of seemingly useful information, and ended up caught in the middle of a controversy. It would have raised a lot less eyebrows if it just appeared as a compressed file on some SIMTEL20 FTP database, and probably conserved a lot of net resources too. You might just pass this back to it's creator. ==================== From: Pat Stephenson Patrick, First of all, I would like to congratulate you on the way in which you run telecom digest. I read it on Usenet; comp.dcom.telecom is one of the best groups around. Keep up the good work! However, I believe that you made a misstep today. Mr Seastrom pointed out two facts about Bernstein's methods of data transfer, and drew the conclusion that Bernsteins method was *not a good thing*. I do *not* agree with Mr Seastroms conclusion. His facts are, however, correct. Seastrom's two points were: 1) The data is *TRANSFERRED OVER THE NETWORK* UNCOMPRESSED. 2) The data is COMPRESSED *WHEN IT ARRIVES AT A RECEIVING SITE* (thus, overall, the compression is done many, many times instead of once) Lets's look at Bernstein et al's command line: > telnet 128.146.1.5 4666 | tail +4 | compress > userlist.Z 1) the *only* data transfer command is "telnet". 2) the "tail" command will buffer the data as it arrives. 2) the "compress" command will compress the output of the tail command. Note that both "tail" and "compress" will run on the *local machine only*. Thus Seastrom's points of fact are correct - data is transferred uncompressed, and compression takes place at every receiver. (In fact, one could get an uncompressed version of the data by saying: telnet 128.146.1.5 4666 | tail +4 > userlist ) Again, I don't think these two points justify Seastrom's flame. But, as points of fact, they are true. Patrick, I have the greatest regard for the way in which you run the digest. I think it is appropriate for you to keep up your high standards by admitting when you are wrong, and apologizing to Mr Seastrom. Pat Stephenson. ==================== From: David Albert In article telecom@eecs.nwu.edu (TELECOM Moderator) writes: >What a laugh. Frankly, Mr. Seastrom, you don't know what you are talking >about.

David Albert | "What are you trying to do, UUCP: ...!harvard!albert | change the world?" INTERNET: albert@harvard.harvard.edu | "No, just our little corner of it." ==================== From: Andy Behrens In article our Moderator writes: (stuff deleted) Robert Seastrom is correct. Patrick Townson is wrong. The file *is* transmitted uncompressed. If you follow the instructions supplied by Ohio State telnet 128.146.1.5 4666 | tail +4 | compress > userlist.Z You will transmit the uncompressed file (all 450K of it) to your own machine, where it will be compressed and saved under the name userlist.Z. Compress is run at the receiving end to conserve disk space; it has no effect on the way that the file is transmitted. (There are apparently technical reasons why the ohio-state.edu machine is unable to transmit compressed files in this case, but that's not relevant here).

This command line sucks the uncompressed file over the net, throws away the first four lines which are presumably headers, compresses it locally, and stores it in a file. You can't send compressed data through telnet because it's not a transparent connection. Blatting 900K of uncompressed data over the chronically overloaded Internet is pretty antisocial; it's not hard to find someone willing to make a compressed version available via FTP.

If you're going to be a unix pedant you should try to get it right. The file doesn't "come compressed," and that's exactly why it has to be piped through "compress," on the receiving host after transmission. It ends up compressed because of that command (hence the .Z), but the compression occurs on the local system, and it's pretty clear from the instructions that the data gets sent along uncompressed. >What a laugh.

A similar problem, though with different motivations, bedeviled the U.S. Army's telegraph lines in the same area in the 1870s and 1880s, and led to the Army's experiments with heliographs. Hostile Indians in the remote parts of the West would cut the Army's telegraph lines. At first, they would just cut the lines and let them fall, but a down line was immediately obvious, and quickly repaired. After a while, the Indians would cut the line, and use strips of rawhide to hold the wire in place. At first glance, it wasn't obvious whether the Indians had cut the wire, or whether a broken wire had been spliced by the Army. Hence, the heliograph. Clayton E.

An unnecessarily hi-tech solution. My family had the same problem [my father is a Family Doctor - the office phone rang almost constantly]. The SIMPLE solution was to REMOVE the BELLs from the office phones. They still made a whirr sound, instead of a noisy ring. Much better, and easily identifiable [plus easier to ignore at 3AM for the rest of the family]. Note that this was technically illegal, since the phone was telco property, but I presume that statute of limitations has expired. I also do the same for my bedroom phones - easier to ignore when I don't want to answer the phone. Unfotunately, my last phone expired and the replacement has an electronic ringer, which I can only turn to lo [still a bit annoying] or off [too quiet]. Ihor Kinal P.S. The other amusing thing was that for many years, the office and home were NOT located in the same residence. But my father still had the office phone in both places. I have no idea how much extra it cost, but it was possible. Some of the extensions needed to have their ringers disabled, since the load was too high. ------------------------------ From: Judith Beall Subject: Re: AT&T Blows Billing on Call To Shoup Salmon River Store Date: 5 Oct 89 07:59:07 GMT Reply-To: Judith Beall Organization: University of Southern California, Los Angeles, CA In article covert@covert.enet.dec. com (John R.

You plug an 8-position miniature phone plug into it. Four wires are used: pins 5 and 4 are tip and ring from the phone company, and pins 8 and 1 are tip and ring to the rest of the phones. The equipment you plug in, most often a burglar alarm, normally bridges 1 to 4 and 5 to 8, so the rest of the phones act normally. When it wants to make a call it can butt in, force a hangup, and do whatever it wants. There are little shorting bars in the RJ31 socket that bridge 1 to 4 and 5 to 8, so if you unplug the equipment the rest of your phones work. The best place for the RJ31 is inside the alarm control box where a burglar can't unplug it easily, but they usually seem to be installed near where the phone line enters the house. Regards, John R.

If you want to know the true story about how fast I was driving when I got that ticket and why I had a handgun in my car, call the Jose Canseco Hotline. Just dial 1-900-xxx-xxxx...." -- Television commercial Maybe I'm preternaturally presumptuous, but something tells me that when Alexander Graham Bell invented the telephone in 1876, he did not do it so youngsters could one day pay $1 a minute to hear a baseball player's rationalizations for driving his Jaguar 125 m.p.h. and keeping a loaded handgun in the car. Nevertheless, the toll call industry is big business, with projected revenues of $1.5 billion for 1989. There are more than 1000 of these 900 numbers, including -- + The US Naval Observatory Master Clock "Eastern Time, 9 hours, 13 minutes, 45 seconds. Universal Time, 13 hours, 13 minutes, 50 seconds." + New Kids on the Block Hotline "Hi, this is Donnie of the New Kids, and it's really cool to be able to talk to you again...." + Laugh Line "Did you hear about the ghost who could never lie to his wife? She could see right through him!" + True Romantic Confessions "My name is Corinne, and I'm a waitress in Reno. For a long time, I had this thing for my sister's boyfriend, and last week when she was out of town...." Among my favorites are the Paula Abdul Hotline, Women's Private Fantasies, Penn State Football Update, NBC Soapline and Telephone Pals. The first 900 number was established in 1980, but the concept did not really take off until about 1986. That's also about the time when the telephone took control of our lives. Until a few years ago, the phone was still a rather basic communications device. You dialed a number; if someone answered you were in business. If no one answered, it meant no one was home. If you got a busy signal, it meant someone was already on the phone, so you hung up and called back later. Now there are more phone features and options than you would find in a new car. If you are expecting a call at home, but you have to go out, you can forward your calls to another number. If you wish to take calls while you are on the phone, there is call waiting. If you want to talk to two parties at once, there's three way calling. If you want to place calls from your car or your boat or your backyard or an airplane, there are car phones and boat phones and cordless phones and airplane phones. If you wear a beeper, you can be reached anywhere. If you wear the Timely Beeper, which is a fake, self-activated beeping device, you can pretend to receive an important call then cut out early on a nightmare date or a disasterous business meeting. As if all that was not enough, Illinois Bell is introducing several new services to the Chicago area. Repeat dialing allows you to dial the same number over and over again for a 30 minute period. This would be a fun feature for the 'Fatal Attraction' types who want to call ex-lovers AGAIN AND AGAIN AND AGAIN AND AGAIN!!!!! Call screening lets customers block calls from designated numbers. This is an especially useful device if your ex-boyfriend is the kind of guy who goes out on Friday night, pops down a dozen beers, comes home at 3 AM, looks through the old photo album while listening to 'your song' and says to himself, "I've got a brilliant idea -- I'll call her now and ramble incoherently, and she'll want me back for sure!" Automatic callback instructs your phone to call back the last incoming call, whether it was answered or not. Say you're at home and you receive an unsolicited sales call from some guy at 9 PM; wouldn't it be fun to call the salesguy back and engage in some recreational harassment of your own? In addition to all these complications, on November 11, the suburbs will switch to the new 708 area code. So for example, if you live in Cicero and you want to call your buddy down the street at 63rd and Pulaski, you'll have to dial 1-312 before his regular number. Phone clutter knows no bounds. Toll-free numbers and toll-call numbers and Dial 9 for an outside line and voice mail and designer phones and credit card calls and designated ringing and Information, what city please? and TickeMaster phone jams and call identification. Oh, for the days of basic black rotary dial phones and HUdson 3-2700! There's only one person I know who still has the traditional dial telephone -- my mother. I wanted to tell her how proud I am that she has never given in to any of this phone gadgetry, so I gave her a call. And was instructed to leave my message after the beep. ==================== [Moderator's Note: For non-Chicagoans, 'HUdson 3-2700' was part of a jingle which played night and day, it seems, on television and the radio for a home improvement service. After telling about their services in the late movie commercial slots, a man's voice would sing, 'Hudson Three, Two Seven Hundred'.

A judge in Pennsylvania has ruled that Calling LINE I.D. (not Calling Face ID or Calling Person ID) is a violation of that state's wiretap statute, which defines a wiretap as a "device which captures the incoming electronic or other impulses which identify the originating number of an instrument or device from which a wire or electronic communication was transmitted." The judge ordered that per-call blocking services be mandated, rather than relying on the billing inserts describing the service and its potential dangers to customers. Technically, it has already been told on this circuit that per-call blocking is available, so the question now is why Bell Atlantic feels compelled to resist it. In any event, this is the outcome of what may lead to other challenges to the offering of this service, noteworthy when the Maryland and Virginia regions of Bell Atlantic are about to have their respective switches turned on.

The pay phone there (Allerton House) was of the post-pay variety. I assume it was on a SxS switch, since when I tone-dialed 0-NPA-NNX-XXXX I got an extended length of silence, with faint clicking as it pulsed out the digits, followed by clunk! Bong! A T and T. (As a side note, it apparently still uses the cry-baby style of not-a-number signal, too.) The oddity is that there was a typed sticker noting that to use other long distance carriers, dial the 6-digit access code or 0+10 digits, and advise the operator of the handling. I've never heard of 6-digit access codes, and trying to dial 102220 got me a reorder before I finished. Dialing 950-1022 gets a reorder, too. Besides, I've never heard of Equal Access on a SxS switch. My best guess (I didn't try it out) is that since I think post-pay phones work by cutting the outbound audio until either the totalizer signals payment or a zero is dialed, maybe the zero bounces the call out to a tandem, so that 0-10xxx reaches other carriers. Or maybe it's just dial 0-NPA-NNX-XXX, wait for the operator, and say "Use MCI, please." Any thoughts? Incidentally, I think this is not an IBT area, since the phone was an AE device. Champaign itself is IBT, though.

This same tactic has been used locally (St. Louis, MO -- SW Bell territory) to credit previous overcharges. I find it annoying and offensive. It deliberately discriminates against people whose telephone service terminates or changes frequently due to moves. For example, there was one such credit about two years or so ago, that was spread out over a period of many months (or maybe a year), with one quarter of the credit applied and then one or two months went by with no credit, and then the next installment of the credit was applied. We lost a portion of this credit because this period extended past the time when we terminated the phone service at my mother's house after she died. She had had this phone service at that address for 35 years or so, and certainly was entitled to the entire amount of credit. But her account only got a portion of the credit she was due. PUC's and the equivalent should require that this credit be issued in a lump sum, not spread out over some long period. Actually, since the telco required the bills be paid in cash, the return of overcharges should be a refund check, not just a credit. The telco wouldn't accept a credit for goods or services from you in lieu of cash as payment of a phone bill, would it? Yet it expects to pay *you* back that way! If it REALLY would be a hardship for the telco to pay back cash (their upper management would have to eat lower-grade caviar in the executive dining room for a couple weeks... :-), then it should be issued as a transferable credit voucher, in one single total payment. Thus it could be used as payment for the recipient's phone bill, or, if they no longer had phone service, could be given to someone else (or sold) who could use it on *their* phone bill. In any case, the credit should be issued to everybody who paid the overcharge, even if they moved out of the area or terminated their phone service in the meantime.

Reid" Subject: New Acquisition for Rochester Telephone [Reprinted without permission from Democrat and Chronicle, a Gannett Rochester Newspapers, Rochester, New York, Wednesday, October 4, 1989, page 10D] ROCHESTER TEL BUYING 4TH PHONE COMPANY IN WISCONSIN Local firm planning to speed up acquisitions By Phil Ebersole, Democrat and Chronicle Rochester Telephone Corp. executives, announcing their 11th telephone company acquisition so far this year, told financial analysts yesterday they expect the pace of acquisitions to accelerate. Their latest acquisitions, St. Croix Telephone Co., serving 5,300 access lines in northwest Wisconsin, will be Rochester Tel's fourth acquisitions in Wisconsin, its 13th in the Midwest and its 22nd overall. John K. Purcell, a Rochester Tel vice president in charge of acquisitions, hinted that Rochester Tel soon may make its first acquisition west of the Mississippi River. Minnesota, for example, would be a happy hunting ground from Rochester Tel's point of view. Companies with fewer than 15,000 access lines, the kind of small company Rochester Tel likes to buy, can increase rates up to 10 percent a year, within certain financial limits, without review by Minnesota regulators. Purcell said he visits 95 to 100 telephone companies a year. In all, there are 483 independent telephone companies in the United States serving more than 1,000 access lines. Fred R. Pestorius, vice president of finance, said Rochester Tel plans to speed up its pace of acquisitions. Other parts of its strategy are to use technology to add new services and to expand unregulated businesses, such as the RCI Corp. long distance service, to achieve economies of scale. Small rural companies generally enjoy faster revenue and profit growth than Rochester Tel's core six-county service area around Rochester. Alan C. Hasselwander, president and chief executive officer, said that's because New York regulators require Rochester Tel to subsidize small rural telephone companies elsewhere in the state, mainly through the way long-distance revenue is shared. By his calculations, those subsidies are equal to $2 a month for every access line. Small rural companies, on the other hand, receive subsidies, said David Mitchell, executive vice president of Rochester Tel's Telephone Group. The logical conclusion, which he didn't draw explicitly, is that it makes sense for Rochester Tel to get on the receiving end. Rochester Tel also has a goal of having one-third of its access lines outside New York state so as not to be dependent on one state's regulators. Currently, about 15 percent of its access lines are outside the state. Other companies -- notably Century Telephone Enterprises of Monroe, La., and Telephone & Data Systems Inc. of Chicago -- also are buying small telephone companies. Mitchel said Rochester Tel won't outbid its rivals by paying more than a company seems to be worth. But Purcell said it has an advantage in its record of allowing its subsidiaries to continue to maintain their own separate identities. He also said Rochester Tel doesn't rule out buying larger companies, but so far none has been offered for sale. The St. Croix acquisition will include New Richmond Cable, a cable television company with about 1,200 customers. It will be Rochester Tel's second rural cable television company, along with one in Indiana. "In our judgment, cable TV is a natural adjunct of the telephone business, offering great growth potential," Mitchell said. Federal law bars telephone companies from the cable TV business in all but the smallest rural communities. Hasselwander said there's a good chance the law will be changed and he'd like to enter the cable business in a few years, after completion of Rochester Tel's fiber optics network, which could carry many channels of TV signals. On Monday, Rochester Tel warned that profits for the second half of 1989 will be less than in 1988. The stock price, which had gone up from $26.625 a share (adjusted for 2-for-1 split) to $44.875 on Friday, fell $2.50 a share on the news. Yesterday it closed at $43.375, up $1. ------------------------------ From: S M Krieger Subject: Re: NPA Splits Before 1965 Date: 5 Oct 89 14:09:10 GMT Organization: Summit NJ > Here's a list of the affected states which obviously had only one code (with > a zero in it, still serving the major city) at one time: > New Jersey 201 (609) > Additional ammunition: telephone directories in New Jersey have listings in > them of every prefix in the state, grouped by area code.

(This does not apply universally in NJ, however. There is some > code conservation with 7 digit calls across the border allowed.) Here is what I remember, from memory, about 201 and 609. Direct Distance Dialing came to Atlantic City in 1961. Prior to DDD, there were five central offices serving Atlantic City (ATlantic City 2,3,4,5, and 6) and one serving Brigantine (COlonial 6). All calls within these areas were made by dialing just the 5 digit number. LD calls were placed by the operator. (Two things- obviously at the time, there could be no duplication of numbers between the AT 6 and CO 6 exchanges; also at the time, the area served by AT 2 and AT 3; specifically, that portion of Atlantic City south of where U.S. 40 ends, as well as the cities of Ventnor, Margate, and Longport, was still developing; the only AT 3 numbers assigned were those of the form AT3-1nnn). When DDD came in 1961, and 7 digit dialing implemented, the AT 2 and 3 exchanges became 822 and 823, the AT 4, 5, and 6 exchanges became 344, 345, and 348, and the CO 6 exchange became 266. Now, several other things- 1. Although the area code instructions showed a national map, included the 201/609 split, we were told that no area code was required for any call within NJ; I guess this meant that 609 was being opened for future expansion. I think it was around 1963 that NJ Bell told us we would need to use the 201 area code for northern NJ. (And confirming the speculation in the original article, the stories about the pending 201/908 split mentioned that originally 201 was the area code for the entire state.) 2. I guess the SXS office was retained for local calls, so any toll call out of Atlantic City required us to dial a 1 before the number. Thus all calls to another area code had to be preceeded by a "1", and all calls within 609 not to Atlantic City, Brigantine, Pleasantville, Somers Point, or Ocean City had to be preceeded by a "1" (and then the 7 digits). This 1+ requirement for all toll calls was deleted a number of years later; I don't know exactly when because my family moved out of the Atlantic City area in 1964. 3. I don't know if the billing system was in place at the time DDD came, because whenever we made a toll call, an operator would first come on and ask what number we were calling from. I think this lasted about a year. I also remember as southern NJ was being cut over to DDD, there was a mention that dialing instructions for calls from certain border areas to Philadelphia had changed. I think from places like Camden, to call Philadelphia, all one had to do was dial 11 and then the Philadelphia 7 digit number. When DDD, they had to dial 1 (215) (or maybe just (215)) like the rest of us. The listing of central office and locality in NJ phone books is pretty old. I don't know though why they flag duplicate central office codes; it's not like we don't need an area code if the code is unique to 201 or 609.

The areas having the most traffic at the time were New York City ( 212 ) and Los Angeles ( 213 ) even though they were a continent apart. These numbers were selected because they were the easiest to dial on a rotary dial. I'm not sure where the break point was in deciding whether a center digit of zero was easier to dial than one with larger end digits and a one in the center. Obviously 202 was easier that 919.

Judice) writes: > This discussion reminds me: Is there any source out there for buying > a genuine new or used AT&T (WE) speakerphone Model 200? > These are the three piece units (Phone, mike and speaker) with a zillion > wires and cables protruding outwards. I don't know what a "Model 200" is, but from your description, might you be referring to the WECO 3A speakerphone or WECO 4A speakerphone? The WECO 3A speakerphone for standalone use consists of a 666-type transmitter unit with on/off switch and volume control, a 760-type loudspeaker unit, a 55-type control unit, and a 2012B transformer. This speakerphone could be used with any single or multi-line telephone set that could be wired for A-lead control (actually, the A-lead control could be eliminated, although this was not a standard Bell System wiring option). There were other options for this speakerphone system in which the transmitter could be incorporated within a Call Director or panel-type telephone set. The WECO 3A speakerphone used discrete transistor circuitry and was designed in 1960 and introduced around 1962. As far as I know, only WECO and Northern Electric (Telecom) manufactured the 3A-type speakerphone. The WECO 4A speakerphone consists of a 680-type transmitter, a 108-type loudspeaker, an interconnecting block, and a 85-type transformer. The amplifier and control unit was built into the 108-type loudspeaker. The WECO 4A speakerphone used integrated circuits and was introduced around 1974. As far as I know, the 4A speakerphone was manufactured by WECO and another firm, Precision Components Inc., who marketed the product as the PC-4A Speakerphone. Both of the above speakerphones employed amplified hybrids with voice-switched gain to minimize feedback. The complete concept of a switched-gain speakerphone is difficult to explain in this forum, but suffice it to say that the transmit and receive sides of the hybrid each have switchable gain which is adjusted so that the channel having the stronger signal has the higher gain. The result is that undesirable echo and singing is virtually eliminated. In addition, there is a compensation circuit for ambient room noise referred to as a NOGAD, Noise-Operated Gain Adjusting Device. The 3A-type speakerphone was the the epitome of clever discrete component design; as an example, the gain control was effected by a special silicon varistor bridge circuit called a "variolosser", whose effective insertion loss was controlled by a DC bias voltage. The 4A speakerphone was a more compact, improved version of the 3A speakerphone which looked a bit more "state of the art", but its operating principle was pretty much the same as its predecessor. While the 3A speakerphone is hardly state of the art, it does not sound too bad as long as one follows certain rules - like keeping the transmitter at least 30 inches away from the loudspeaker. The 55-type control unit in the 3A speakerphone is especially versatile, and I have modified them to do all sorts of things over the years using non-WECO transmitters and loudspeakers. I have utilized the 55-type control unit as the heart of various door-answering and other types of handsfree intercom systems. > I've had these units in my office, along with newer AT&T (System 75/85 > compatible sets), and I don't think anything has ever rivaled their > quality or durability. Fortunately I have one in my office now, but > I'd like to get one for my home office. I agree! I still have 3A speakerphones in my house and in my office at one of our facilities. I think they still sound great, and may even sound better than the fancy Northern Telecom SL-1 electronic handsfree telephone in my office at another facility location. I don't know where you can obtain any of the above speakerphones, but they do appear surplus from time to time. While I don't care to part with any extra units that I have, I would be willing to furnish the complete schematics and technical data should you manage to obtain one. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: Kent Hauser Subject: Technical Question About Caller ID Date: 6 Oct 89 04:08:32 GMT Organization: Twenty-First Designs, Wash, DC How is the calling number transmitted under Caller ID?

The installer would intentionally swap out one of the standard gongs on each instrument in a large office full of 500/2500 sets this would make all the sets give a distinctive sounding ring. As far as I can tell, these special gongs disappeared from the catalogs about the same time as the advent of modular jack/cords on phones. They worked well, but certain combinations of gongs made for some really odd sounding ringers. Today, in our interconnect co., we still install 2500 sets with conventional mechanical ringers. (We use Premier 2500, but Comdial's and Cortelco's are OK, too) We tell our customers that the 2500 is still the most durable and reliable telephone instrument we know of. Dumb, but dependable (a lot like Centrex, i guess ;-) ) I do not like the electronic ringers. It appears that some people with certain types of hearing loss have trouble hearing the ring of these as well. We often use 2500 models with "TAP" (controlled timed on-hook flash) buttons and message waiting lites. The light acts as a visual ring indication, as well as providing message waiting indication on PBX's with the feature. The TAP or flash button makes transfers easy and the hookswitch is timed to provide a postive disconnect. These enhanced sets are known by different nomenclatures depending on the mfr., but we call them 2507's or MW/TAP sets (for message wait/TAP). They make single line operation behind PBX's and Centrex much easier for most users. We adjust the ringers by: 1. Swap ringer gongs. Try swapping between sets for effect. The right and left gongs have different tones. Try a set with two left gongs, for instance. 2. Adjust ringer normal springs and gongs. The gongs are not center drilled, but are instead intentionally drilled off center to allow adjustment. Rotate them slightly while the phone is ringing for effect. 3. Use black electrical tape along the rims of the gongs to adjust tone and persistence of the gongs. You get a different sound depending on where the tape is placed, and how long a piece you use. (Note: REAL telephone men use gray electrical tape, not black!) If you like 2500 sets, the very best were made in the late 70's and early 80's by WECO, ITT and Stromberg-Carlson. They had: 1. Metal ringer frames 2. Heavy metal baseplates. (Made by Led Zepplin?) 3. The newer electronic bubble-feel type touch tone pads (no mechanical arms inside) (this is the most common item to fail on a 2500 set. the older pads failed much more often.) 4. Polarity guards. 5. Some were fully modular corded, but many were quarter mod. Note that all 2500 sets by the standard mfr.'s are date stamped on the bottom. I buy used sets meeting the above specs often at Hamfests and from brokers. They are worth putting new plastic on. They will often outlast some of the newer sets. Since the mfr.'s of decent 2500 sets have all recently increased their warranty period to five years, the quality has bounced back a bit, though. Gee, I could be excommunicated from the Secret Society of Telephone Installers for divulging these secrets! BTW: Neon lights are indeed an excellent visual ring indication. Try using lights set up for standard 110VAC, often prepackaged in a cartridge with pigtail lead. This is what we use to retrofit message waiting lights on standard 2500 sets.

Zone numbers include either two or three digits, including the leading zero. The following numbers are currently in use : 010->016, 019, 02, 03, 041, 050->059, 060->069, 071, 080->087, 091. The two zones with two digits are big zones, and numbers inside them have seven digits (spelled xxx.xx.xx) ; the other zones are smaller, and numbers there only have 6 digits (spelled xx.xx.xx). There is thus room for n * 10e8 different numbers (where n is < 1, maybe in the 0.7->0.9 range). Zones 041, 071 and 091 are centered on big towns, and could potentially become big ones some day. I suppose this is the reason why the other numbers starting with 04, 07 and 09 have not been used. A pseudo-zone, 017, is used to access the cellular phone system, which by the way is unified between Belgium, the Netherlands and Luxemburg. Special services, including various specialized operators, DA, etc have numbers starting with a '1', and are always dialed locally. There are the '100' and '101' national emergency numbers (resp. fire/ambulance and police). All others have 4 digits. For most services, the second digit is '2' or '3', depending on the language you wish to use (French or Dutch). 'Green numbers' (aka 800 for you North Americans) start with either 11, 15 or 17, and have six digits. They are always dialed locally, and are valid all over the country. Those starting with '11' are completely free for the caller, while for the others a single unit is counted for each call. Those number may give access to a foreign subscriber (for example 11.00.10 is ATT in the US - no other US carrier on the list). Rotary dials are standard 1 to 0. If letters have been used, that's very long ago : the telephone that used to sit in my parent's house, installed in the early 50's, did not have letters... DTMF is now commonplace, and is (of course) free. In some regions, the RTT did even replace all instruments when a new DTMF CO was installed. This did not happen everywhere, however. Customers who wanted a DTMF telephone could still ask for the replacement and pay a flat fee (this was before one could *buy* and install). ------------------------------ Subject: A Problem of False 911 Calls Date: 6 Oct 89 23:12:37 EDT (Fri) From: Larry Lippman In article jenglish@doctor.tymnet. com (Jim English) writes: > An interesting thing happened yesterday at work.

It made me think, if thats as far as the 911 people can > trace a call, and say our Network Control cannot trace it back to > whoever originated it, how would 911 put a cap on computer pranksters? As far as I know, there is no way for either "original" 911 service or the E911 enhanced service to block calls from a given number in any 911 central office serving area; i.e., there is no action which can be taken on the part of the public safety agency handling the 911 calls to prevent this problem from a _technical_ standpoint - except to demand that the telephone company discontinue ALL telephone service to the offending lines. While it is theoretically possible for the software in an ESS central office to block a given directory number line from dialing a 911 call, I have not heard of such a service offering. Furthermore, in my opinion it is unlikely such an option would ever be offered due to potential liability on the part of the telephone company (if you offer a feature such as this, then some telephone company craftsperson at some time is going to screw up and disable 911 for a line *in error*). As I understand the law enforcement community, this problem is going to be dumped squarely upon the subscriber whose lines are being used to make this calls. The subscriber WILL SOMEHOW SOLVE THIS PROBLEM, or someone in authority is going to be charged with "falsely reporting an incident" (or the equivalent crime in your state) and/or the public safety agency will request that the telephone company disconnect service to the affected lines. Most telephone companies have a general provision included in their tariffs permitting them to discontinue service to any subscriber in the event that said subscriber uses their telephone service to harass or otherwise interfere with the telephone service of other subscribers. Such a tariff provision could be invoked in this instance of false 911 calls. I can assure you that if this false call problem is not solved, the responsible public safety agency will bring considerable pressure to bear upon the telephone company to discontinue service as mentioned above. Any public safety agency that I can think of really does not care about the "intentions" of a subscriber whose telephone service is being abused by third parties to make false 911 calls. Such a public safety agency wants the problem stopped NOW, somehow, some way, and they don't care about the details. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Sat 7 Oct 89 11:50:53-CDT From: Clive Dawson Subject: What Happens When a Phone Hangs Up? I've had several years of trouble-free operation from my Panasonic KX-T2425 phone answering machine. This changed about a month ago; it now exhibits some very annoying behavior, but I'm not sure if this is a problem with the machine, or whether it is caused by a change in the behavior in the central office switch, or whether it is caused by a change in the length of my outgoing message. (This last possibility didn't occur to me until just now, and may be the most likely.) What happens is that anytime somebody decides to hang up and not leave a message, I get a "message" anyway consisting of: One ring tone "If you'd like to make a call, please hang up and try again. If you need help, please hang up and dial your operator." One minute's worth of the loud, fast tone denoting that your phone has been left off-hook. Skipping past as many as 5 or 6 of these a day is getting to be a pain. Questions: -- Is it possible that my machine has lost its ability to detect a remote hang-up? Do Panasonic machines detect remote hang-ups, or do they simply detect silence on the line in order to decide whether/when to start/stop recording? -- Is it correct for the off-hook warning stuff to be triggered under these circumstances? Is this the norm? -- Is the length of time before the off-hook warning triggers a settable parameter in ESS switches? The current timeout seems to be 30 seconds, which is precisely equal to the maximum length of an outgoing message on many (Panasonic, at least) answering machines. This means that the warning starts just when the machine goes into record mode, checking for sound on the line in order to decide whether somebody is leaving a message. -- Would it be wishful thinking to believe I could convince the Telco folks to lengthen this timeout period to, say, 45 seconds or a minute? -- Do other people have this problem? I suppose the obvious thing to try is to reduce the length of my outgoing message. Maybe if I can get a few more seconds of silence before the off-hook warning starts, the machine will properly conclude that no message is forthcoming and hang up. Any help/comments/suggestions appreciated!

Then WE > could tell the verification operator to do her thing. What you relate is rather unusual. I can conceive of no useful purpose in providing the facilities to terminate a central office line from each CO in an official PBX trunk (the necessary interface) at manual DSA position used for verification. Telephone companies *discourage* verification, and certainly would not provide such direct access as a benefit to the customer; if the customer wants verification, then they dial "0". No telephone company personnel would want to verify a line, either from a business office standpoint or for installation/repair purposes. Even a craftsperson working on a repair problem has no need to talk to a verification operator because a verification position has no test apparatus and can tell a craftsperson almost nothing useful to facilitate a repair. A craftsperson working on a repair deals with a local test desk equipped with various test and measurement apparatus, which is furthermore staffed by a technically-qualified craftsperson. It seems more likely that you dialed a number which terminated at a local test desk in a repair service bureau. Every CO that I have seen has a local number which terminates at a local test desk, which may be local or remote to the CO; in some cases the local number is less than 7 digits, like "770" or "951". While a local test desk certainly has access to test trunks from the affected CO and could in effect perform the function of "busy line verification", I am rather surprised that they would do so without challenging your identity. Then again, I suppose that anything is possible in downstate New York. :-) Also, according to an official New York Telephone Maintenance Telephone Directory for the NYC and LI areas, the 9901 number (along with the 9970) was commonly used as a "charge/no charge" test line used for toll and coin line supervision testing. > In about 1973 or '74, we could no longer reach a verification operator > on official-1, but rather, 234-9901 would bring one up capable of > verifying anywhere in 516. Almost all No. 1 and No. 3 Toll Board (combined with DSA) positions have multiples for outside CO lines which terminate in the position using an "official PBX trunk" circuit. It is most likely that you found such a direct CO line. However, I would be extremely surprised if in fact all of area code 516 was verified at a common DSA facility, since there are MANY CO's in Nassau and Suffolk counties. I suspect that area code 516 is broken up into at least 3 DSA facilities which handle verification. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: Thu, 05 Oct 89 14:08:44 EDT From: "Hisle, Debra" Subject: Phone Design For Appearances We're just finishing up a completely remodelling a bathroom and have reached the select-a-phone stage. The bathroom is done out in high style, with a marble floor, glass block dividing walls, etc. Showplace type of thing. We've included wiring and box for a wall phone. We've got two lines into the house, so the phone needs to be a 2-line. The problem seems to be finding a two-line wall phone. A preliminary survey (I went to Radio Shack last night) turned up (1) a "real" wall-phone (the kind that predates Trim-line) that only comes in Almond (absolutely ghastly choice, given the color scheme of the room) or (2) a small number of feature phones. We'd prefer a Trim-line style, not much in the way of buttons, like Radio Shack USED to sell, but discontinued. We may end up moving one of this type from another room, and getting a feature phone for that location. The problem is, while looking at phones, I kept seeing attractive one-line phones, that would complement the rest of the design in the room. (What I really like is a Trim-line style in a clear housing.) So my question: is there ANY WAY to provide an external line switch to a one line wall phone? We're talking about a flush mounted to the face plate type of wall phone, NOT one that has a cord dripping down to a baseboard height outlet. Or, should I just settle for the plain white trim-line that I can move from another room? And if I DO settle, is there any kind of switch that can be provided for the table-top phone with which I replace the trim-line? (A mahogany boxed model would do quite well in that room, actually.) Selection of two-line phones is so limited... Deb [Moderator's Note: Get a mini-switch at Radio Shack to mount on the single line instrument of your choice. It has to be a four-pole, double-throw switch. From the phone center store (or Radio Shack, if they have it) get a 'side ringer', or separate bell in a little box to mount elsewhere. If you are content with having the phone ring for only one of the two lines then you can skip the extra bell. Bring the four wires/two pairs into the phone, up to the switch. Solder them on the switch so you either bring one pair out to the network on the phone, or the other pair, by flipping the switch. Drill a little hole in the phone shell. If you look on the inside of the plastic, you will likely see little places where punch outs were intended. Mount your switch in there. Now flipping it one way brings line one to the network (and the bell, should the phone ring); and flipping it the other way brings line two to the network (and bell). When the phone is on-hook, however you have the switch set will detirmine which line will ring the bell. Run a pair to the separate bell (and leave the switch by default in the *opposite* position) if you want to have both lines ring a bell. A better way is to get a switch which will do a couple things at once and wire it so that whichever line is switched to the network, the *opposite* pair is switched into the bell. Of course be sure and disconnect the bell from the network, and require it to get fed only from the jumper coming from your switch! This will enable you to be on one line and have the phone actually ring if a call comes on the second line.

Since the phone company does not listen to what you talk about on the phone, they are hard pressed to prove the line is used for business; but if you ask for a directory listing under 'Widget Company' or whatever, it becomes apparent the phone is for business purposes, and the phone company will bill it as such. The difference in cost is purely a matter of what the telco in your community charges for one service and charges for the other, but yes, usually business service is more expensive.

Panel telephones were rather neat, and I remember them fondly from the 1960's when they seemed so *futuristic*. :-) Panel telephones were also made as a 5-line keyset, along with an internal speakerphone option (although an external 55-type speakerphone control box was required). I don't believe that panel telephones are still manufactured for single-line residential use, but an equivalent type of instrument for installation in control consoles may still be manufactured by such vendors as Allen-Tel, Northern Telecom and Plantronics. An interesting Bell System offering which came out in the early 1960's (about the same time as the panel telephone) was the 1A Home Interphone System. This system required two-line "turn-key" telephone sets, often of the Princess variety. The system had capabilities for answering one CO line and placing it on hold, in addition to providing local intercommunication between telephone sets within a residence. There were also some handsfree intercom options, which included the ability to answer the front door using an outdoor transmitter/loudspeaker. There was even a feature which integrated the 1A Home Interphone System with a 1A or 1A1 key telephone system for residences with up to three CO lines. The Bell System had grandiose plans during the 1960's for a 1A Home Interphone System in every home, along with a chicken in every pot, but alas, the 1A Home Interphone System was a turkey which was over-priced and simply never sold to within a fraction of expectations. Speaking of chickens and turkeys - believe it or not - there was also the 2A Farm Interphone System. This apparatus was similar to that of the home variety, except that it had higher-power outdoor loudspeakers for intercom purposes, in addition to providing electronic tone ringing over the outdoor loudspeakers. Some of the BSP sections on the 2A Farm Interphone System have really precious drawings of typical installations on a farm, including house, barn, silo, a loudspeaker in a chicken coop, etc., along with a smiling farmer (with overalls and hat) talking to a smiling wife (reminiscent of Mrs. Cleaver) in a bedroom! If you think that the above interphone systems were turkeys because very few were ever sold, there is something even worse, the Edsel of the Bell System, PICTUREPHONE [tm]. Some years ago I heard a rumor from a "well-placed source" at AT&T that the Bell System had lost over $ 300 million on Picturephone; while that may not seem like much money today, picture :-) it in terms of 1960's dollars and it becomes much more significant. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" [Moderator's Note: There were also a few panel *pay* phones around. The post office at 211 South Clark Street in Chicago has two of them in the lobby. Slightly larger than the home models, these are also completely recessed into the wall, with a single slot on the top for the money. These were installed when this post office opened, in 1973. Apartment building front door 'enterphone service' provided by Illinois Bell (a CO-based service) also uses panel phones, but with armored handsets instead of the old kind which retracted back into the wall. And for quite a few years, *the* picturephone center was located in the lobby of the Illinois Bell HQ building, 212 West Washington St. They had a rather nice looking conference room set up, with camera, speakers, etc, and they rented it out by the hour to companies wanting to have picturephone conferences with a branch in some other city. PT] ------------------------------ From: Kenneth_R_Jongsma@cup.portal.com Subject: PA Judge Rules Against Caller ID Date: Sun, 8-Oct-89 13:37:18 PDT In a large article that I will attempt to sumarize, this week's Communication Week reports that a PA Judge has ruled that some CLASS features are illegal under the states wiretap laws. The judge ruled that premise devices that display the caller's number constitutes a "trap and trace device" described and prohibited by the state's Wiretap Act. A "trap and trace device" is defined by the Act as "a device which captures the incoming electronic or other impulses which identify the originating number of an instrument or device from which a wire or electronic communication was transmitted." The judge ruled that to make the service legal, Bell Atlantic would have to allow subscribers the right to block their number _on a per call basis_. Bell Atlantic was not going to do this, rather relying on bill inserts and advertising to make consumers aware of the potential use of their number. Interestingly enough, the judge also questioned some other CLASS services and said that they should be investigated. One example he gave was the Return Call service, where a subscriber could call the last person that called him/her by pressing a code. This without knowing the number being called. The judge said that combining this service with optional local service detailed billing would reveal the callers number when the bill finally arrived a few weeks later. ken@cup.portal.com [Moderator's Note: What the judge does not seem to realize is that lots of information is available when acquired *through billing channels* instead of simply asking for other reasons. Did you ever wonder who a non-pub number belonged to, and you could not get the information on it? Call it via your calling card, or through third number billing, or with other operator assistance. When the billing comes, *challenge it* at the business office. "Who is this I am supposed to have called?"...."Do you know John Smith, at 123 Main Street?"......"oh, is that who it was?

Airtime rates for Genesee Telephone are: * 17.5 cents a minute during peak time, 8 a.m. to 6 p.m. Monday through Friday. * 16 cents a minute during off-peak time, 6 p.m. to 9 p.m. Monday through Friday and 8 a.m. to 9 p.m. Saturday, Sunday and holidays. * 14 cents a minute during night time, 9 p.m. to 8 a.m. all week. Association airtime rates for Rochester Tel Mobile are: * 17.5 cents a minute during daytime hours, 7 a.m. to 7 p.m. * 17 cents a minute during evening hours, 7 to 11 p.m. * 15 cents a minute during night hours, 11 p.m. to 7 a.m. Those who aren't members of associations getting discounts from Rochester Tel Mobile must pay 35 cents an hour during daytime, 25 cents during evening and 20 cents at night. The charges are made for both outgoing and incoming calls. Customers of both companies pay a $20 monthly access fee. In addition, cellular telephone customers must pay message unit charges for local calls and toll charges for long distance calls. Genesee Tel customers pay standard message unit charges throughout the five-county Rochester area (Monroe, Wayne, Ontario, Livingston and Orleans counties). But, through a quirk in the system, Rochester Tel Mobile customers don't have to pay message unit charges for calls between locations in the five counties subject to long distance charges, such as calls between Sodus and Canandaigua. Both companies get discounts on long distance rates. Genesee Tel customers who call outside the Rochester area must pay 15 cents a minute for calls elsewhere in New York state, 18 cents a minute for calls elsewhere east of the Mississippi and 22 cents a minute for calls west of the Mississippi. Rochester Tel Mobile offers 15 cents a minute for calls elsewhere in upstate New York, 28 cents a minute for calls to New York City and a 10 percent average discount from AT&T rates for calls elsewhere in the United States. ------------------------------ From: Gabe Wiener Subject: AT&T Long Lines Reply-To: Gabe Wiener Organization: Columbia University Center for Telecommunications Research Date: Sat, 7 Oct 89 18:14:19 GMT I was just thinking about the AT&T Long Lines that have been used in this country for decades. I'm sure all of these questions have ridiculously simple answers, but here goes anyway. 1. Over the _really_ long runs, such as through the Rocky Mountains, or through the deserts of the southwest, how do they prevent line resistance from degrading the signal to a point where it would become undetectable? 2. When one of those lines is damaged out in the middle of nowhere, and the damage is _inside_ the cable, how do they locate it? Moreover, how do they splice in a new piece of cable? In other words, how do they connect up those hundreds of individual lines? It would be like trying to rewire a spinal cord. 3. Are the long-lines used today by AT&T digital or analog? Sprint obviously is touting their fiber-optics, but what is AT&T doing? Do they still use the analog long-lines that they've been using for years? Or do they send the signals over them via a digital encoder? Thanks... Gabe Wiener - Columbia Univ.

Seems that 214 started running out of NXX's and they quickly (with less than two months warning) added the prefix requirement. :-( There are also ajacent calling areas, like Arlington / Grand Praire those poor people are just now getting used to prefixing 214/817 when dialing across the street. ;-) Since it appears that Waxahachie will be 903, they should be good and warmed up, cause they are gonna have to get used to dialing 903 as well, when calling someone down the block. Good trivia question, what's the most area codes in a local calling (non EMS, or extra charge) area you know of? I'm sure three isn't the most, but it's gotta be up there. Anyway, since my office is in one of the areas that will be serviced by 903 and my home EMS service isn't supposed to be effected I wonder if I will still be prefixing the calls with 214, or 903..

He had gone to work as usual about 2:00 pm that afternoon at the telegraph office downtown, where he worked full time as a telegraph operator. In an article in the [Chicago Tribune] in 1901, on the occasion of the thirtieth anniversary of what was then commonly referred to simply as 'The Fire', Mr. Read discussed the events of that Sunday evening and the Monday following. As those of us today remember without question where we were and what we were doing when we heard of JFK's assasination, and our elders recall in detail what they were doing when the news of Pearl Harbor came over the radio, Read talked in detail about the assasination of President Lincoln, then got into a detailed account of the fire, and the operation of the telegraph office at that time. In those days, in addition to circuits from major cities across the United States, the office had numerous local circuits around the city. Nearly every major mercantile establishment, every bank, and every hotel had a telegraph key, or sometimes more than one. The Chicago Board of Trade alone had three keys. A few wealthy and important citizens had them also, such as Mayor Mason. The federal courthouse and City Hall were equipped. Mr. Read pointed out that 'it was nice to work on Sunday or at night, because the local keys were usually silent; on occassion the mayor would have something to send, or the business men, but normally our only traffic at night or Sunday was to or from out of the city, and then not too much.' He also pointed out that 'a benefit for the employees in those days was they gave you a key to use at home; you had to pay for the key but they let us send messages for free wherever we wanted. Many guys just used their key to call down to the office and chat in their spare time...' Something similar to what we today would call an annunciator was used in the office to tell what key was active at any given time. The electrical current would cause a little colored strip of metal to sort of bounce and 'flop over' with a louder than usual 'clicking noise'. This caught the operator's attention, who would look and see what was what, and respond accordingly. The fire started about 9:30 pm that Sunday night, on the west side, at what today in 1989 is numbered 837 West DeKoven Street. Ironically, today the site is the Fire Prevention Bureau of the City of Chicago. But in those days, it was a private home owned by a Mr. and Mrs. O'Leary. According to Read's account, and substantiated by other historical accounts, the real panic began when the fire did the 'impossible', and spread across the river into the downtown area. Everyone assumed the fire would burn itself out when it reached the west bank of the Chicago River....but the wind was quite strong, and some burning embers were carried in the wind to the other bank where they landed on one of the outbuildings of the Chicago Gas Works. A rather large explosion soon followed when the Gas Works blew up, knocking most of the south side of the city into darkness when the gas lamps went out. Read said he watched it from the office, and the assumption was it had to stop someplace, but the strong winds and limited resources of the Fire Department combined to keep the inferno going. He said maybe it was around 11 pm '.....and the guy who usually worked all night did not show up; I was both annoyed and concerned. I couldn't leave until he arrived, and the fire was obviously going to take our office sooner or later.....about midnight, I guess, Mayor Mason came in with the police superintendent and had me begin getting emergency help in. They had me contact General Phillip Sheridan of the Army, to tell him they needed troops and whatever assistance he could give.' 'Well you know those wires were not private, not like the telephone of today (1901!!) where you can talk and assume no one is learning your business with you. I guess within thirty minutes or so, most of the guys I dealt with all over the United States were busy chattering about 'that big fire they're having in Chicago'; which was good actually, cause the relief efforts started that same night.' 'Finally about one o'clock, the fire had spread to the building next to us and I sent a message out; I remember just what I said; to anyone who is getting this message, I was signing off, if I did not get out the roof would probably collapse on me.' Read said he gathered up what papers and records he could, along with the money in the cash drawer and locked everything in the 'fire proof safe' and left the building. He had been out of the building less than a minute when the building caught fire -- the dry timber it was -- and in perhaps twenty minutes it was nothing but ashes, with the metal safe standing there alone, along with melted keys and wire, some other charred remains. Curiously, the wires exited the building in such a way that the majority of them were not harmed at that point once they left the building, but within an hour they had melted or the poles around town had caught fire and fallen down. He said he spent the rest of the night just wandering around downtown watching the fire. '....I knew I would never see such a spectacle again in all my life....and there was nothing I could do at the office, since it was gone anyway....' Read noted in the Tribune interview another pitiful aspect of the fire: Where the firemen were making what efforts they could to control the fire and limit its spread, no one thought to protect the Water Works. In those days, like now, the water was drawn from Lake Michigan, but the pressure in the mains was obtained by diverting some water into a stream along-side the building, where a water wheel was spinning. This water wheel in turn drove some hydraulic gears which pumped air into the mains, forcing the water along from air pressure. When the fire spread to the Water Works building itself, that was the end of the pumping machinery, and at about 3:30 am Monday morning, the city's water supply shut off. At that point, said Read, the firemen said in essence to hell with it. The fire continued burning virtually unabated until about 10:30 pm Monday night when rain began falling which put out what was still ablaze. The manager of the telegraph office and several of his men met early Monday morning to survey the damage and get service restored as soon as possible. 'By about noon, negotiations were complete and we bought a building over on Canal Street near the Customs House, and we relocated in there along with the post office.....what was just incredible was the tangle of melted wire laying everywhere all over town....some of it melted by the fire into the most grotesque shapes imaginable...it was about three weeks before we were able to reconstruct everything; I don't know to this day why the office records were not filed elsewhere; sometimes we were just guessing about who had what before the fire....' 'The main thing we figured was to get the out of town circuits going again, and Tuesday afternoon they had strung up a wire that connected in over at 18th Street which got us our line back to St. Louis and a couple other places. Lucky we found some keys that had not been damaged too badly and we were able to use them. I think in a minute or less after the wire to St. Louis was restored they must have heard us down there, cause they got on their key and started passing traffic they had been holding for the past day and a half. I think everyone in the United States at that point must have had friends or relatives or business of some kind in Chicago because we got so much stuff in the next twenty four hours you would not believe it. For about six months after that, we had a huge amount of traffic around the clock it seems. Relief agencies, government officials, newspapers wanting to know about the fire; you name it. I think within about six months most of the merchants downtown had rebuilt; I know the courthouse was rebuilt and the Board of Trade rather soon, and the local wires were pretty much back the way we had them I guess six or seven months later. By the summer of '72 things were pretty much back to normal in our office.' Robert Read did mention, when prompted by the Tribune writer, that he had been given a 'meritorious award' by Western Union afterward for his efforts to protect company property the night of the fire. He laughed and said 'you know, they opened the 'fire proof safe' the next day -- everything in it was charred; I guess from the terrible heat of the fire -- a lot of what I put in there that night were the records they could have used in the weeks following had they not been rendered illegible from the soot and heat.... maybe I should have carried them all out of the building....home with me or something.'

Besides being arrested, some telephone "rustlers" who steal open wire lines (still common in the west) are in for another rude surprise: some wire which they laboriously remove that *looks* like copper, is really copper-clad steel - and is worth essentially nothing. I know of one instance where this happened. Copper, even of the "hardened" variety, is simply no where near as strong as steel. Most open wire lines which have been erected or replaced in the past 30 years use copper-clad steel, also known as "copper-weld". Copper-clad steel is used in other outdoor applications, such as 1-pr through 6-pr aerial drop wire, "bridle wire" used to make connection to open-wire lines, etc. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ End of TELECOM Digest V9 #437 *****************************   Date: Tue, 10 Oct 89 23:33:29 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest V9 #438 Message-ID: <8910102333.aa08496@delta.eecs.nwu.edu> TELECOM Digest Tue, 10 Oct 89 23:32:35 CDT Volume 9 : Issue 438 Today's Topics: Moderator: Patrick Townson Re: What Happens When a Phone Hangs Up?

Possibly, but more likely, your telco has installed a new switch, probably a DMS running a rotten generic that doesn't provide reliable CPC. This is that brief interruption in battery that lets key systems and answering machines know that the distant party has hung up. > -- Is it correct for the off-hook warning stuff to be triggered > under these circumstances?

All of the Panasonic answering machines that I have encountered detect and utilized CPC. On my 1ESS lines, my old Panasonic would reset immediately, even if the caller hung up just a few seconds into the outgoing announcement (OGM, for you Panasonic afficianados). It must also be pointed out that the 1/1A ESS switches have the BEST CPC in telephony. It is immediate, solid (at least 600 ms), and totally realiable. > -- Would it be wishful thinking to believe I could convince > the Telco folks to lengthen this timeout period to, say, > 45 seconds or a minute? Oh yes, I'm afraid so. Those timeouts are "cast in stone" in the generic. While they can be adjusted in the field, I can't imagine a telco monkeying with them because a residential subscriber was inconvenienced in the operation of his answering machine. What you might complain about instead is the lack of reliable CPC. I know of people who have complained very loudly and have actually been rewarded with results in this area. The NT DMS is notorious for this problem but it is also correctable with the proper programming. > -- Do other people have this problem?

That would be one band-aid solution. I would first start with your telco and find out if they have installed a DMS recently. If so, rag on them about CPC. If not, find out what it is (and then rag on them about CPC). John Higdon | P. O.

My best guess is that callers hear my machine pick up and hang up right away, or hang up a split-second *before* my machine picks up. Either way, it seems to trigger the off-hook warning. On the bright side, the fast reorder-like screech causes my machine to hang up, so I only have to fast-forward past the voice. [...] > -- Do other people have this problem? Yup.... :-( Roy M.

When I was working at a 3rd party Teletype(tm) repair shop in the 1979 -1980 timeframe we had two buildings, and a crossbar PBX. We had sleeved the line relays for extensions 200, 201 and 202, and connected them to a pair of relays hooked to a pair of 2A amplifiers. Dialing 200 would pull in both relays and page in poth buildings, 201 paged in the north one, 202 in the south building. When the night bell was enabled from the console, it's dry contacts "rang" on both amplifiers via the ring cycle contacts in the interrupter from an old 551B key system (the Hitachi AX2S switch had night bell contacts that latched shut). The 2A amplifier was based on germanium transistor technology, and had a relay- enabled built-in oscillator. We also keyed the "ring" tone with a time clock for breaks and lunch. I still have a xerox of the 2A BSP, and yes, the drawings are very cute. I think that the system could have been marketed better - the hardware worked well, and would have been ideal in small businesses.

I suppose this is the reason why the other numbers > starting with 04, 07 and 09 have not been used. This is an historical artifact. Some (ten?) years ago all telephone numbers in Belgium were changed. Before that time a telephone number consisted of a two digit area code (including leading zero) and a 6 digit local number, or a three digit area code plus a 5 digit local number. So a telephone number was always 8 digits including area code. This changed overnight throughout Belgium to a telephone number of 9 digits including area code. In most places the local number got an additional digit. The exceptions were the cities with area codes (at that time) of 04, 07 and 09; there the area code was changed and the local number unchanged. > Special services, including various specialized operators, DA, etc have > numbers starting with a '1', and are always dialed locally.

When I was in Belgium this summer I checked it, but as far as I know all special numbers are 3 digits starting with either 1 or 9.

This reminds me of a place I used to work which had an autodialing burglar alarm. The alarm was triggered by opening any of several protected doors from the public corridor into the private office space, with a 30-sec or so delay. Authorized personnel were supposed to come in through one particular door, near which was the keypad which would let you cancel the alarm before it called the alarm company. The alarm control box was installed right next to the keypad. An intruder would have no doubt as to what the box was because when the timeout expired the box could be heard pulse-dialing with a relay (click-click-click... click-click-click-click-click... etc.). The sound was unmistakeably that of a telephone dialer at work. Of course the box was locked. But, leading out from the box and stapled to the wall in plain view was the standard beige-jacketed 4-conductor inside phone wire! Obviously if one didn't want to take time forcing the lock on the control box, a simple snip of the phone wire would keep the box from calling anybody! And, since it used pulse dial, there'd be plenty of time to hear the dialing, notice the wire, and cut it... The same place had a lock on the elevators, so that after hours, you had to use a key or the elevators wouldn't stop at their floor. (The stairwell doors were normally locked from the stair side.) The control panel on which the lock was mounted (inside each elevator car) was secured by six ordinary phillips-head screws. The keyswitch was positioned right next to the button for the floor, making its function rather obvious ("Gee! This button doesn't work! I'll bet this lock has something to do with it!"). Unless its backside was protected in some way a simple clip lead across its terminals would suffice to "hot wire" the elevator. No doubt they had paid big bucks for all this stuff, and felt secure... I pointed all this out once, but they didn't want to hear it, to put it mildly. --- Jamie Hanrahan, Simpact Associates, San Diego CA Chair, VMSnet [DECUS uucp] and Internals Working Groups, DECUS VAX Systems SIG Internet: jeh@simpact.com, or if that fails, jeh@crash.cts.com Uucp: ...{crash,scubed,decwrl}!simpact!jeh ------------------------------ From: "Michael H.

As related in "Broadcast Engineering" several years ago (more than twelve) a radio station had been having a problem with "copper rustlers" stealing their antenna grounding radials. These are conductive lines which radiate outward from the base of AM transmitting antennas to provide a good ground plane. (Note FM and TV do not require them because they are higher in frequecny, the "tower" is not the radiating element, and the antennas are structured differently.) This particular station had a marshly low land near it's antennas where the radials had to be elevated over the ground, thus making them easy prey. This caused frequent and severe distortions to their transmitted field, to say nothing of the frequent cost of replacing long stretches of heavy gauge (#12 or better) copper wire. A bright engineer decided to replace a significant number of the radials with barbed wire. The rustling stopped shortly there after, although evidence did show they tried (remember most of this was done at night and in this case over treacherous ground). Later "proof of performance" tests showed their radiated pattern still remainded well within FCC specs and the barbed wire remains there to this day.

Levine" A judge here in Massachusetts finally cut off unemployment benefits to NYNEX workers because NYNEX persuaded him that there has been a "significant curtailment of business." This puts more pressure on the strikers to settle. On the other hand, yesterday's Boston Sunday Globe reports that many large business customers who are NYNEX's bread and butter are now bypassing NYNEX to hook up to LD carriers, since NYNEX can't hook them up at this point anyway. They are unlikely to un-bypass when the strike is over, and this will be a major hit on access line revenues. It also says that the overtime they have to pay to non-striking supervisors working 60 hour weeks appears to consume most of the savings they get from not paying the strikers.

Most central office apparatus handling subscriber loop signaling requires a line open of at least 150 ms before disconnect. At a dialing rate of 10 pps with 60% break, the 60 ms line opens during dial pulsing are no where near long enough to cause a loop disconnect. The 150 ms timing is determined by one of the following, depending upon the type of CO apparatus: release time of slow-release "B"-relay in a trunk circuit; electronic timer equivalent of "B"-relay in a trunk circuit; or programmed loop supervision scan time in ESS apparatus. Therefore, theoretically, dialing into a completed connection with returned answer supervision should not result in a disconnect. However, from a practical standpoint, such a disconnect will happen, and ONE CANNOT ASSUME THAT PULSE DIALING INTO A COMPLETED CONNECTION IS A RELIABLE METHOD OF SIGNALING. The most common reason why disconnect will occur is maladjustment of DX signaling circuits and SF signaling circuits. Such maladjustment is generally undetected since it will not interfere with dialing PRIOR TO RETURN OF ANSWER SUPERVISION - which accounts for the ONLY type of dialing situation that a telephone company will ever consider. Pulsing tests and apparatus lineup on a DX or SF circuit are always conducted in the absence of answer supervision; after all, when you dial a normal telephone call, your dialing MUST be completed prior to answer on the far end! Properly balancing a DX circuit to pulse without distortion in the presence of answer supervision is much more exacting than balancing such a circuit to pulse without distortion in the absence of answer supervision. Improper SF level adjustments on an SF signaling circuit, such as an E-type or F-type unit, will also result in dial pulse distortion. Now, what happens is that the resultant dial pulse distortion causes an effective line open which is long enough to be interpreted as a valid CO apparatus disconnect signal. The above disconnect situation could not happen on a call where the interoffice trunk path was say, totally T-carrier, because signaling in the presence of returned answer supervision is not an adjustment problem on digital carrier apparatus. However, introduce a DX or SF trunk segment, and the problem is likely to occur. There is nothing that you, as a vendor of telephone apparatus seeking to interpret dial clicks, can do about this problem. It is beyond your control, and not an area which can be subject to any regulatory complaint. My personal opinion - which you can take with grain of salt - is to NOT offer this dial pulse detection option. The negative reaction of customers who become disconnected may well offset the positive value of this attempted feature. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ Date: 9 Oct 89 11:23:18 PDT (Monday) Subject: The Hottest Answering Machine From: Lee_C._Moore.WBST128@xerox.com Because of a service person who went wild in my house, I am now shopping for a new answering machine.

On certain exchanges (I presume the newer System X ones) BT are sending customers itemised bills, but only for calls of 50p or over. Most residential line calls are under 50p each as they are made outside office hours. Meter units are 5.06p each and a unit gives you around 5 mins of a local call off-peak (I think). 50p for a local call is for a long call! Medium to long distance calls may go over the 50p. The only calls which will really show up on the bills are the ones to car phones (STD codes 0836 and 0860), to value added services (0898, 0055, 0066, 0077) and international calls. I don't know if BT charge for itemised billing (a possibility) and I think the facility is only available in a very small part of the country. P.S.

The fact that the OCCs routinely use AT&T facilities to complete calls to remote locations is equally unknown to press and public.

It seems that he answered the phone and the caller was some woman who was worried about her water being cut off because of a billing problem; he told her she must have a wrong number, she read off his number, he asked where she was calling from, she hesitated and then said "St. Louis" and hung up. Worried that she might actually have her water cut off, he wrote the letter to the St. Louis newspaper in an attempt to help.

For the "really long runs" to which you refer, we are dealing with coaxial cable and microwave systems, as opposed to individual pairs per circuit, and/or short-haul carrier such as N-type FDM or T1 PCM. Analog coaxial cable and microwave systems all work on single-sideband suppressed carrier to provide FDM (Frequency Division Multiplex). Analog coaxial cable transmission systems, such as L1, L3, L4 and L5 carrier utilize various types of repeaters which are placed at periodic intervals along the cable route. L1 repeater spacing is 8 miles; L3 is 4 miles; L4 is 2 miles; and L5 is 1 mile. Most repeaters are self-powered using DC which is superimposed over the RF signal on the coaxial cable center conductor. Every 160 miles for L1, L3 and L4 and every 75 miles for L5 are power feed points which are located in small repeater buildings or hardened underground facilities. These power feed points require AC power, but have back-up batteries and generators. Microwave transmission systems are by their very nature limited by the curvature of the earth, and therefore require repeater towers every 20 to 30 miles, with each tower obtaining local power with battery/generator backup. Some examples of long haul microwave systems are the TD-2, TD-3, TH-1 and TH-3. Digital coaxial cable transmission systems, like the T4M, require digital *regenerators* (like a repeater, but not quite the same) every mile, with each regenerator being powered by DC superimposed on the coaxial cable center conductor. Incidentaly, the capacity and specs of the L-type coaxial cable systems, as per their original design are: L1 (obsolete) 600 channels per two coaxial tubes ~2.8 MHz bandwidth L3 1,860 channels per two coaxial tubes ~8.3 MHz bandwidth L4 3,600 channels per two coaxial tubes ~18 MHz bandwidth L5 10,800 channels per two coaxial tubes ~70 MHz bandwidth Most L-type coaxial cable systems use either 12-tube or 20-tube coaxial cables. Accordingly, as an example, an L4 system using a 20-tube cable (with 2 tubes spare) provides a total of 32,400 voice-grade channels per cable. That's a LOT of channels! L5 is three times greater in capacity. The L-type coaxial cable systems are used to provide "hardened" communication routes which are relatively immune to natural and man-made distaster (including nuclear war). As a result, the hardened routes are always underground, but some non-hardened L-type coaxial cable are above ground. Underground routes are also preferred because they result in greater transmission stability since cable temperature changes are minimized; when one is trying to push maximum bandwidth from a coaxial cable and maintain amplitude stability, temperature effects become significant. Digital methods (PCM) are being used to update both coaxial cable and microwave facilities. As an example, the T4M system transmits digital data at a rate of 274 megabits/sec (DS4), and can use the same coaxial cable as in the L5 system; L5 and T4M can furthermore co-exist in the same cable. In the case of the T4M, however, the repeater modules are replaced with regenerator modules for the designated coaxial tubes. It is important to understand that practical digital transmission systems require MUCH MORE BANDWIDTH THAN ANALOG SYSTEMS. While a single T4M channel with two coaxial tubes (one for each direction) provides 4,032 individual voice-grade circuits, the equivalent L5 analog FDM channel provides 10,800 voice grade circuits. Stated another way, the T4M system will handle 168 24-channel D1 channel banks. A new generation of microwave systems have been designed to directly interface with digital carrier. As examples, the 1A Radio Digital System will handle one 1.544 megabit/sec DS1 line per channel; the 3A Radio Digital System will handle one 44.736 megabit/sec DS3 line per channel; and the 18A Digital Radio System will handle one 274 megabit/sec DS4 line per channel. There are also DS4 interfaces for fiber optic systems. It is therefore possible for a signal to leave one customer premises as digital and travel thousands of miles through all manner of wire, coaxial cable, microwave and fiber optic systems and enter a second customer premises while remaining 100% digital. > 2. When one of those lines is damaged out in the middle of nowhere, > and the damage is _inside_ the cable, how do they locate it? There are two general methods of fault location, usually performed sequentially. The first involves supervisory pilot tones to localize repeater and/or gross cable faults. Obviously, if there are say 16 repeaters in a given line segment, and from ONE END of the segment supervisory pilot tones can only be received from repeaters 1 through 11, then the fault is most likely between repeater 11 and repeater 12. A similar feature using audio tones is used to localize faulty regenerators in digital transmission systems. Once an approximate fault location is made as above, entry to the cable is made from a repeater location where impedance measurements can be taken and/or a time domain reflectometer be used to pinpoint the exact fault location, often to within a few feet. > Moreover, how do they splice in a new piece of cable? Very carefully. :-) Critical circuits are generally re-routed using alternate facilities to permit any cable work. Splicing coaxial cable is not trivial, and some time must be allowed following a splice for moisture to be purged from the cable tubes, and for the transmission characteristics of the cable to stabilize before equalization can be performed and the cable placed in service. > In other > words, how do they connect up those hundreds of individual lines? One at a time. :-) As implied above, on long-haul coaxial cable circuits there are comparatively few lines since multiplex is used. A 20-tube coaxial cable has, of course, 20 tubes, plus maybe a dozen or so 19 AWG conventional pairs for order wire, repeater power and test purposes. > It would be like trying to rewire a spinal cord.

Or do they send the signals over them via a digital encoder? I'm afraid that I have been out of the mainstream of the telephone industry far too long to quantitatively comment on the percentage of digital versus analog FDM circuits in use by AT&T. The only thing I can state with certainty is that there is still a SIGNIFICANT number of "long line" circuits which run through analog FDM facilities. One of the reasons why a large number of analog circuits remain is that going digital using the same cable facility results in at LEAST 2-1/2 TIMES >FEWER< voice-grade channels. It is not easy to economically justify converting, say, an existing L5 facility to T4M while at the same time >reducing< its channel capacity by 250% just to go digital for the sake of going digital. Sprint, as an example, has somewhat of an "unfair" advantage over AT&T. Sprint started with ZERO plant investment, and immediately had the freedom to go state-of-the-art digital over the MOST LUCRATIVE high-density circuit routes. AT&T does not have this luxury, and furthermore has a lot of toll plant serving CO's in the middle of nowhere where circuit revenue is far less that circuit installation and maintenance cost. The eventual goal is, of course, for AT&T to have all-digital network using fiber-optic communications, but the reality of the situation is that so much money is invested in existing microwave and coaxial cable plant, including FDM carrier, that it will be a LONG time before the goal of an all-digital transmission network can be realized by AT&T. Don't forget, the AT&T network is larger than Sprint by orders of magnitude! <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" ------------------------------ From: Dave Esan Subject: Numerical List of NPA's and NXX Count Date: 11 Oct 89 20:42:22 GMT Reply-To: Dave Esan Organization: Moscom Corp., E.

Note of course that 312 is splitting, and will reduce its number of nxx's in the next 6 months, 214 is scheduled for a split, as is 201. 202 and 301 will have more room now that they must dial a 1 to other DC area codes, 415 is scheduled for a split. 416 recently removed the has allowed the implementation of NXX where previously only NNX was allowed. Most interesting to me is that 212, and 213 which both have split in the last five years are nearly full enough to qualify for a another split.

Actually, unfortunately, this is for real. You can dial the number and hear a few minutes of incredibly boring Jose Canseco. Just because somebody is good at hitting a baseball doesn't mean he's not a twit. (In fact, being good enough at hitting a baseball to make a million dollars a year probably means you are a twit.) I read somewhere that this gimmick is the bright idea of Jose's agents, who are always on the lookout for ways to cash in on Jose's name (not to mention the names of the other people the agency handles). They justified it by saying that people know up front that it costs real money, and that people really want to know what Jose thinks about stuff. It also, incidentally, pays Jose (and his agents) a nice piece of change. I like to watch the guy play ball (did you see the 500+ foot home run he hit in Toronto?), but I never listen to what he says because it's so stupid. Apparently there's at least one fan in Oakland who agrees: During the last regular season game televised from Oakland, I saw a sign in the outfield bleachers that read: "Hey Jose! 1-900-IMA-JERK!"

I bought my first answering machine over a year ago. It was a two-cassette model, with a list of features a mile long. It had *exactly* the same problem as Clive mentions, except the recorded message was something like "The number you have dialed is a long distance number ...". Anyway, I tested this with a friend, putting in every manner of call (long message, short message, no message, and combinations in sequence). The bottom line: the machine screws up if a hangup occurs *before* the outgoing message completes. Solution: I bought an el-cheapo machine (single micro-cassette), but it serves perfectly (remote answer, excellent response, hangups or otherwise). Note: a friend explained that the VOX (voice activated control) circuits on these machines are their key features.

I called the phone company and asked to speak to somebody at my CO. The conversation went something like this: SWB: Fairfax. Can I help you? Me: Can I speak to a technician? I have a question about the DMS-100 switch. SWB: Are you a vendor? Me: No, I'm a customer. SWB: A customer? How did you get this number?! Me: I called the Southwestern Bell and they connected me. SWB: Well, you should have called the repair number. Me: Yes, but then it would have taken two extra days to finally get the person I need to talk to. I just have a question. SWB: Well, hold on then. ... SWB: This is -----, can I help you? Me: Yes, I have an answering machine which can't detect when the other person hangs up. I think it might have something to do with the CPC signal. SWB: What's your phone number? I give it to him, and hear him typing something on a keyboard. Thirty seconds later: SWB: OK, I've set an option on your line which will fix the problem. Me: Thanks a lot!! SWB: Sure. Any time. Sure enough, the problem is fixed. Rarely have I had such a satisfying encounter with the phone company!!

You might be pleased to know that AT&T Technologies, Inc. STILL MANUFACTURES these, or something similar, apparently to the ORIGINAL "Survive a nuclear war" specifications (and in the U.S.A.)! As I mentioned in an earlier article, we just installed a new AT&T System 25. Since some of our single line people required headsets, and since there was some shortage of "new-improved" style phones or their headset adapters, we were given BRAND NEW 2514BMW (!) sets, complete with headset jack on the back and Plantronics headsets, which AT&T resells (ouch). On our phones (2514), however, the "turn button" is to switch between the headset and the handset, rather than between lines like on the 2515 mentioned by PT. Also, when the button is PRESSED (not turned) it produces a timed break for putting people on hold in the System 25. NOW, the problem that remains is that people walk up to when you're wearing the headset, and they can't readily tell if you're on the phone or not. If they are familiar with the phone, they'll carefully inspect the turnbuttom to see if it's in the "on" position, meaning headset, meaning you're probably in the middle of a call. But it's hard to see that. What would be nice is if the turnbutton had a light in it that lit up when you were using the line (just like the buttons on the old multi-line desk sets we recently praised).

The big regulatory reform *I'm* waiting for is on in-state long distance charges. It costs me more to call Los Angeles at NIGHT rate than to call the East Coast during DAY rate -- on the SAME long distance company (true for AT&T, Sprint, and MCI, all three). Even more expensive than calling Los Angeles (400 miles) is calling Ukiah (150 or 200 miles), because the latter is in my LATA and thus Pac*Bell monopoly territory. Indeed, it seems that most of my phone calls are charged INVERSELY proportional to distance. What POSSIBLE justification can there be for leaving in-state rates so high? I pay six or seven times as much for some in-state calls as I would for comparable-distance interstate calls.

The service to which you refer is known as ADAS (Apartment Door Answering Service), and was primarily available in CO's served by No. 1 ESS and No. 2 ESS. There was actual ADAS hardware in the CO which was connected to each subscriber line, but I never actually saw it and don't know any technical details. The lobby telephone was a touch-tone panel telephone, with the prospective visitor dialing an abbreviated 3-digit number (selected from a directory chart) to reach the desired apartment. A call-waiting feature was automatically implemented with ADAS in the event that a regular CO call was in progress at the time of an ADAS call, or vice versa. The entrance door was opened by the subscriber dialing a particular single digit. A CO pair provided a switched 48 volts to operate an interface relay in the apartment building, with the contacts of this relay being connected to an electric strike which opened the entrance door. More than one entrance door/electric strike could be accommodated. The timing interval for the electric door strike was controlled in the CO, and was a customer-specified option. With the advent of divestiture and related changes in the way BOC's operate, I suspect that ADAS may be no longer offered for new installations, although I could be wrong. I haven't seen an ADAS installation in a good many years. > And for quite a few years, *the* picturephone center was located > in the lobby of the Illinois Bell HQ building, 212 West Washington St. > They had a rather nice looking conference room set up, with camera, > speakers, etc, and they rented it out by the hour to companies wanting > to have picturephone conferences with a branch in some other city. PT] As far as I know, the Bell System Picturephone >CENTERS< did not in fact use the station apparatus which is commonly referred to as "Picturephone". Instead, the Picturephone Centers used conventional video cameras and monitors, with the camera being typically hidden behind a wooden panel, having just its lens protrude. While the station-variety Picturephone service used video bandwidth compression to about 1 MHz, as far as I know, the Picturephone Centers arranged their conferences using a standard broadcast-quality 6 MHz monochrome video channel. I have taken part in a few Picturephone Center conferences, with the most recent being about 12 years ago; in fact, somewhere I still have a souvenir ball-point pen given out by New York Telephone after attending a conference at their Picturephone Center at Columbus Circle in Manhattan. :-) The Bell System charged exorbitant rates for use of Picturephone Centers, which hardly placed Picturephone conference center use within the reach of "the masses". I suspect that offering Picturephone Centers was merely a face-saving effort on the part of the Bell System to keep the Picturephone name "alive", since it had obviously died as a customer station offering. As implied above, the Picturephone Centers offered no service which had any resemblance to the proposed *switched* Picturephone service of the 1960's. The original switched station Picturephone concept was rather clever, and so was the circuit design. There were neither integrated nor digital circuits in the original Picturephone design, and the resultant size and performance did indeed represent a significant design achievement. Incidentaly, having once been directly involved in the telephone industry, and having known many people at AT&T, Bell Labs and the Bell System operating companies, I have tried, tried, and tried over the years to get my hands on a surplus Picturephone station instrument - with no success. A significant amount of Picturephone apparatus - ranging from Picturephone station sets to CO line repeaters to special KTU's to 5-line keysets with *pink-colored* keys for Picturephone-equipped lines - was manufactured in the, ahem, "anticipation" of sales which never materialized. All of this apparatus seems to have disappeared from the face of the earth; it has either been quietly scrapped over the years, or now resides in a super-secret storage location, perhaps presided over by Elvis Presley. :-) I would be most curious to know if any other Telecom readers have ever managed to lay their hands on any surplus Picturephone apparatus. I have known a few Bell Labs employees who were ham radio operators and had real motivation to obtain surplus Picturephone apparatus for amateur television purposes - but even they were unsuccessful in their efforts. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?" [Moderator's Note: When I said '*the* picturephone center' I did not mean there was only one everywhere; I meant only one in Chicago.

PT] ------------------------------ Date: Wed, 11 Oct 89 23:31:51 CDT From: TELECOM Moderator Subject: ADAS Applications in Chicago In the first article in this issue of the Digest, Larry Lippman gives a technical description of Automatic Door Answering Service, or ADAS. In this message, I will describe three installations here in Chicago. Each of the three has certain things in common with the other two, yet each has certain features not found on the other two. First, some definitions: The pre-divestiture ADAS here was marketed by Illinois Bell as 'Enterphone Service'. It was a CO-based offering, with all equipment in the central office except for the relay which allowed the building entrance door to be unlatched. After divestiture, this service could no longer be provided by Illinois Bell; however existing customers were grandfathered; several still remain in operation. The post-divestiture ADAS is marketed by *Illinois Bell Communications*, (a subsidiary of Ameritech, as is Illinois Bell *Telephone Company*) under the name 'Interphone Service'. This is premise-based equipment, and the unit they were selling a couple years ago was manufactured by GTE/Canada. Both systems do essentially the same thing: A panel phone is located near the entrance to the apartment building or small office complex. Vistors use the phone to dial a three digit code number, from a directory of tenants posted there. The three digit code, for security reasons, does not relate to any specific apartment or building location. It is up to the person who answers the call to give you that information. In both instances, the three digits dialed are translated to a specific wire pair (either a dedicated pair from the CO to the apartment, or a house pair to the apartment in the case of Interphone). The device camps-on the pair and first tests for busy. If the line is free, it rings the telephone attached. If the line is busy, it sends a 'call-waiting' tone. The telephone rings in a different way (usually two short rings) to advise the apartment dweller of the nature of the call; allowing it to go unanswered if desired, without fear of missing a 'real' phone call. The apartment occupant answers the phone. In the case of call-waiting, the CO line is put on hold while the door is answered. After conversation with the party at the door, the occupant can choose to admit the visitor or deny entrance. Dialing '4' causes the electric striker on the door to release for a given period, usually five to ten seconds. Dialing '6' denies entrance. If either the occupant or the visitor simply terminates the conversation by replacing the receiver, this is treated as a denial. If a call was on hold, it 'rings back' to remind the person to continue the original call. In either case, the phone line is disconnected, and the occupant is automatically returned to the call in progress if there was one, or is given dial tone. Calls from the front door are limited to a total of sixty seconds, including the time the phone is ringing. Less sophisticated systems use an auto-dialer as part of the premise equipment to dial the directory number of the occupant. A hazard to this approach is that unless the occupant has call-waiting, a visitor at the door would recieve a busy-signal. This style of unit is not used very often these days for this reason, as well as for security problems. The I/Enterphone system does not honor call-forwarding, nor will it send a signal to a physically-bridged off premise extension, such as an answering service. The CO-based system will allow an OPX to manipulate the entranceway, but only if by coincidence the pair from the CO is multipled somewhere in the vicinity of the subscriber's premises and no one bothered to open it up. Both systems are subject to having answering machines accept the call if no one is at home; thus a visitor at the front door can leave a message for the resident if desired. If the occupant for whatever reason does not have telephone service, then an accomodation is made as follows: In the CO-based version, Illinois Bell provides the occupant with a black, rotary-dial phone good for answering the door only. At any other time, the phone is dead. No battery, no sidetone, nothing. It has no directory number -- just a pair assignment. In the premise-based version, the vendor supplies a few phones to the proprietor, or landlord, who is responsible for giving out the phones to new tenants until such time as their regular phone service is connected and they have instruments of their own. If a tenant has more than one phone line, then usually when the ADAS is installed, one line or the other is selected for use with the door. In some cases, the ADAS line is kept on a separate instrument not associated with phone service even if the tenant does have a phone. Illinois Bell *Telephone* leases their CO-based ADAS for about $100 per month. They charge $50 for the common equipment at the CO; $10.75 for the front door phone and CO line; $10.75 for the circuit to the front door and associated relay (which is on premises); plus $1.00 per tenant/ month. Typically, an apartment building with Enterphone has between 30-50 apartments being serviced. Repair of the system with a four hour turnaround, seven days per week, twenty-four hours per day is guaranteed. The landlord of course is responsible for repair of the door and the electric striker, plus the wiring from the premises relay to the door. The building address is flagged in business office records so that any change in service; disconnection of service; installation of new service or whatever MUST take into account the pairs from the CO dedicated to the building. A tenant may be cut due to a credit disconnect, but the Enterphone stays on, since this is billed to the landlord. The pairs can never be assigned to another location, and are tagged this way in the CO. The Illinois Bell Communications premise-based system is offered for sale only. No lease is available, however there are repair packages offered. Like the CO version, once in operation, the incoming pairs from the CO terminating in the building IT, or main terminal are tagged, and installers who come to the building for any reason MUST make sure not to swap out house pairs and CO pairs without keeping things where they belong on the Interphone. One Interphone system here uses a panel speakerphone rather than a regular phone at the front door. It goes 'off hook' when the first digit of three is pressed on the buttons. Another building here uses Interphone also, but that system has both a front and back entrance connected. Tenants dial '4' to open front door, '5' to open back door and '6' to deny entrance at either. In addition, this building has an 'extension' of the front door phone at a desk where the receptionist is seated. The receptionist can call any apartment to announce guests already in the lobby. The receptionist also has a code on the outside phone (dial zero) for someone wishing entrance such as a delivery person. A third building here has Enterphone, but it is hooked up in such a way that the manager and building engineer both have 'extensions' to the front door phone in their apartments, and can call tenants. Interphone can be equipped with a special, secret three digit code which functions like a 'loop around': Dial it, and the system responds by simply unlocking the door. Needless to say for security reasons, this information remains a secret with the building manager or caretaker. Interphone code numbers can be changed easily with simple programming using a phone plugged into the control unit. Enterphone code numbers are a bit more difficult, and require a change order in the business office, with attendant fees for the work, etc, and a lot of beaurocratic hassles.

There are also many of them in the BART stations and in many public buildings. It is very strange to hear them spoken of as if they were extinct. I also remember the "three-slot" type which looked very much like the single slot but apparently had the standard (of the era) "dings" and "gongs" mechanism behind the panel. However, while we're on the subject of turkeys, the "card dialer" deserves at least an honorable mention. The touch tone model, while a little spiffier than its rotary counterpart, seemed to be a journey to the absurd. The effort in locating the correct card, inserting it into the slot, then letting it dial was more effort than dialing the number in the first place. Programming the cards (by punching out the little holes) was an exercise in complexity. And then of course, you couldn't reprogram the cards; they were discarded, meaning that you had to depend on telco for an endless supply. The cards were not free. John Higdon | P. O.

MCI, whose 10 percent market share makes it a distant number two to AT&T's 75 percent, says its giant rival is resorting to false claims in the hope of stemming the loss of 100,000 customers to MCI each week. AT&T, however, says it will defend itself with a countersuit. According to AT&T spokesman Herb Linnen: "We welcome the opportunity to discuss who is misleading whom...we have been quite concerned for some time now about MCI's misleading print and broadcast advertising. We have taken our complaints directly to MCI without success." He added, "AT&T stands behind its advertising." This latest litigation is simply the latest chapter in MCI's long and very bitter battle with AT&T, which began in the 1970's when MCI successfully broke AT&T's long-distance monopoly by offering 'Execunet', the first long-distance service bypassing AT&T offered to the public. The two companies have battled each other at the Federal Communications Commission, which authorizes the rates for each, ever since. This is the first time since AT&T's divestiture that the arguments have been taken into a courtroom. In an interview, MCI Chairman William McGowan said that "AT&T ads are sleazy", and he noted that the nine month old campaign grew increasingly negative, forcing MCI into the courts. AT&T responded saying that MCI is resorting to the courts since "...they just can't hack it in the marketplace...." McGowan responded that he believes a lawsuit is the only way to fight a company which is spending two million dollars a day on advertising. He said, "Our budget is big -- $51 million -- but how do you compete with someone who is nine or ten times your size in advertising?" MCI is still studying the impact of the latest round of AT&T ads, but McGowan said he is sure MCI should have gained "a lot more" than 100,000 customers per week if not for the advertising. The advertising has not affected professional telecommunications managers, but does have an impact on individual and small business customers, he said. The MCI suit, filed in U.S. District Court in Washington, DC, alleges that AT&T's advertising campaign "maliciously attacked MCI's honesty and the value of MCI's products and service by falsely and deceptively representing that it is superior to its competitors in general, and MCI in particular, in terms of trustworthiness, quality and price. MCI's suit cites AT&T ads that assert MCI's rates are cheaper than AT&T's only when calls are made over 900 miles away and after 7 p.m. MCI's suit also takes umbrage at AT&T's advertisement which states that MCI customers "might have better luck calling Mars than trying to reach MCI representatives for an explanation of their bills." The ads, the suit charges, also claim non-AT&T companies provide slow telephone connections; that other companies do not operate worldwide like AT&T; and that competing 800, facsimile and WATS services are inferior. The suit says AT&T "has wrongfully profited and MCI has been damaged by being wrongfully thwarted from maximizing its sales potential." The suit asks the court to order AT&T to ***discontinue advertising its services for a period of one year*** and that advertisements after that time be approved by the court and carry a notice to that effect in the advertisement itself. Additionally, it asks for profits "wrongfully amassed" by AT&T on the sale of its products and services during the past year, plus interest and legal fees. McGowan was particularly irked by a claim that MCI's fax service has 57 percent more problems than AT&T faxes. He said that number was arrived at by figuring the difference between AT&T service -- with 4.9 percent errors -- and MCI, with 7.7 percent errors. Rather than reporting the 2.8 percent difference, the ad claims a 57 percent higher rate -- the percentage increase between 4.9 percent and 7.7 percent. "Talk about misleading," McGowan said. "Yes, talk about misleading," said Herb Linnen. "They've survived this long in part based on the deceptions they've used on a public not well educated on the technical aspects of telephony....we'll clear this up once and for all in court with a countersuit."

With the new system came a new prefix for State of Illinois offices in Chicago and a few other 'minor glitches' as the first phase of the system switched into operation. The network, intended to give Illinois government state-of-the-art technology at cheaper prices was inaugarated last week for state buildings in Chicago, Joliet, Collinsville and Springfield. "There were some minor glitches that had to be worked out", said Michael Lang, a spokesman for the Central Management Services Department, which oversees the state's telecommunications network. I guess so. The 'minor glitches' include calls to state telephones being disconnected in mid-conversation, a problem still not remedied several days later. The most noticeable change for most callers -- other than having to call two or three times to complete one conversation -- was the new prefix assigned in Chicago. Now it is 814 plus the extension instead of 917 as in the past, for the 5000 telephone lines in the State of Ilinois Center in Chicago. With the new system, connections will allegedly be much clearer and cheaper because the equipment is programmed to 'least-cost routing' to complete calls. When completely installed, sometime in 1991, the new system will also transmit video images. The new system was installed by Illinois Bell and Sprint under a joint venture contract over the next seven years that calls for a complete redesign of the telecommunications network here. Also included in the contract is a provision to train government employees to staff, manage and repair the system as needed.

The upshot of earlier notes in & out of Telecom is that Md. & Va. suburbs are being removed from area code 202; therefore, 202 will have more room. This does not affect the room in areas 301 or 703 except that some prefixes previously-forbidden near DC (i.e., duplicating DC or the suburbs across the Potomac) will be allowed there. Local calls in the DC area will require 10 digits if crossing area code boundary (no leading 1, which is required on toll calls from there), thus permitting some current 11-digit local & extended area calls in the DC area to reduce to 7 digits later. ------------------------------ Subject: Re: Numerical List of NPA's and NXX Count Reply-To: johnl@esegue.segue.boston.ma.us Organization: Segue Software, Cambridge MA Date: 12 Oct 89 14:23:16 EDT (Thu) From: "John R.

That makes sense. 215 and 302 are both geographically quite compact and relatively urbanized. That means there are relatively few places that need prefixes of their own, so the telco can fill up a prefix before issuing a new one. Compare that to 907, Alaska, with 337 prefixes and 403, Alberta, the Yukon, and part of the NWT, with 575. Neither contains very many people, but they're all spread out and so you have lots of prefixes serving only a few hundred people each. ------------------------------ From: Eric Schnoebelen Subject: Re: Coordinate Tape Info Request Date: 12 Oct 89 19:11:37 GMT Reply-To: Eric Schnoebelen Organization: Central Iowa (Model) Railroad, Dallas, Tx.

This is but one of the "simulated facilities" features made possible by electronic switching. The term "simulated facilities" is actually an in-house term used by Pac*Bell personnel. Call waiting and "Ring Master" are commonly known SF services, where telco provides some of the functionality of additional equipment without actually tying it up (call waiting--"like having two lines", etc.), but Pac*Bell has the best scam going. It's called WATS service when associated with Commstar. If you have a WATS line with Commstar, you don't actually have a physical line. You dial a code (such as *14) to "access" the WATS from any line in the Commstar group. This is "simulated facilities" at its finest. You pay the monthly for the WATS ($25.00) but the telco doesn't have to provide a line. Dialing the code simply executes a class of service change for that call (changes the billing number). Fun with your phone: Dial the number readback code. Your number is announced. Then dial your WATS code followed by the number readback code. The POTS number for your "simulated facilities" WATS line is announced. > [Moderator's Note: As a matter of fact, in the version of this offered by > Illinois Bell, called 'Selective Ringing', you *do* get distinctive call > waiting tones for each line.

This appears to be part and parcel of that mini-Centrex-type service. You only get one "beep" on Commstar Call Waiting as well. Incidently, I am told that Commstar (or Starline) is simply a sub-group of a real Centrex group. If you know others with Starline or Commstar in your prefix, there are some interesting tricks you can do. Even so, it is possible to transfer any call on your line to any other phone in your switch, regardless of prefix or features on the destination line. John Higdon | P. O.

We use repeaters, spaced anywhere from 1 to 30 miles, depending on the type of carrier technology. These repeaters are powered by DC current carried down the same pairs of the transmission. Each direction takes one pair, one for the E->W and the other for W->E (no, I'm sorry, but AT&T does not go N->S or S->N ) Actually, all repeaters will show an East/West transmission, just to keep things easy. On the older technology based repeaters, they were vacumn tube amplifiers; later came solid state amps; and now with digital transmission, they are not repeaters anymore, but rather regenerators. They actually regenerate the signal at each repeater location, rather than just amplify it. This has the immediate advantage of not amplifying the noise base along with the signal. > 2.

Ahhhh, back in the good-ol-days....:-} All the wires within a cable are color coded, in pairs. In larger cables, pairs were grouped into bunches, which in turn, were color coded themselves. So while tedious, it was not overly difficult to match pairs in a splice. As to locating the fault, it's really pretty simple, you just measure the resistance out to the fault, use a formula (which has long since escaped me) to figure out the distance from the test board to the problem. Careful measurments and calculations would usually drop the splicer right on top of the problem. > 3. Are the long-lines used today by AT&T digital or analog?

The answers are: we are rapidly converting our entire network over to digital transmission, where we are in that project, I can only guess.

Unfortunately, Mr. Levenson has missed the meaning of my posting, probably due to scanning/excerption. In my article, I referred to a decent solution phone, no longer marketed by Radio Shack, and mentioned that I have one, in another room. THAT room is the candidate for a single-line-with-external- switch phone; NOT the bathroom. Mahogany boxed would be a lovely choice for the library, but I just can't see it in an Art Deco bath. The phone for the bath WILL be wall-mounted -- to an actual wall-mount plate, NOT just mounted on screws like most feature phones will do, in fact. Thanks to our moderator, I have a viable approach to either building an unassuming switch box, or modifying a nice wall-phone. In further developments, I've found in the Fordham catalog that SWBell makes a 2-line Trim-line wall-phone, which will probably fit the bill. My husband and I have run into difficulties agreeing on designer phones anyway -- he can't get used to the idea of a clear phone, actually.

Then, he goes on to say that because of the large embedded base of analog technology in the AT&T network, it will be a long time before AT&T's network is 100% digital. I pulled out my copy of the 1988 AT&T Annual Report, published in February 1989, to see if it had anything to say on this subject. Here's what I found on page 4: "By mid-1989, 95 percent of our domestic switched traffic will be carried digitally, increasing to 100 percent by the end of 1990. By the end of 1992, all private-line facilities will be digital as well. With our new digital lightwave systems, we quadrupled our domestic fiber-optic capacity and, by laying the first trans-Atlantic fiber-optic cable, doubled circuit capacity between the United States and Europe. We plan to install more fiber-optic cable in the Pacific, Caribbean and the Atlantic." Obviously, Larry's discussion left out all the fiber we have in our network. We have been deploying fiber-optic cable for several years. In fact, we have more route miles of fiber than any other carrier. Keep in mind, too, that the capacity of a fiber cable is quite high. The 1.7 gigabit/sec systems that we have been installing for the past year or two have a capacity of 36 DS3s, or 24,192 voice-grade circuits. And that is for one pair of fibers. A typical cable has many pairs of fiber, many of them still sitting unlit. We also have a significant amount of digital coax and radio already out there. So, it won't take as long as Larry fears for AT&T's network to become predominantly digital. It has already happened. I'm not even sure that the targets I quoted above for becoming 100% digital are still valid. Given the number of times AT&T has decided to accelerate its digitization plans, those public statements from February could be out of date already.

Just a couple of wee little points from little ol' me. I was in Chicago for the first time on Friday 10/6. Really loved it. But I was in for a little disappointment when I went to IBT headquarters downtown looking for the Telephone Pioneer museum. Seems that IBT is gutting ("renovating") the inside of their building, so they decided to remove "expendable" spaces like the aforementioned exhibit room. The receptionist was friendly and sympathetic - she said that the management types never realized how popular the room was, but that it probably won't be coming back. I had to satisfy my telephone fix at the centrex display on the street level. Not quite the same. :-( Also, WVOA is now the 105.1 classical FM station in DeRuyter, NY, formerly WOIV (and a number of other things). It's owned by Forus Communications, a religious broadcasting group, and broadcasts satellite-programmed classical music to a hell of a lot of cows in rural upstate New York. I actually preferred the former religious format - when in the right mood, I considered it high comedy. :-) The new WVOA was once part of the New York State Rural Radio Network, a group of five stations covering the territory from Buffalo to Albany programmed from the current WQNY in Ithaca. The network was put on the air by the GLF farm cooperative, was sold several times, then wound up in the hands of ConTel (a favorite organization of this news- group). The FCC cried foul, so ConTel was forced to divest in an interesting fashion -- they turned all five stations over to Pat Robertson's CBN for *free* in 1970 or thereabouts. The stations were sold off individually in the early 80s.

In Australia we have card phones which accept Amex and Visa, but not MC, for some reason. They also accept most bank debit cards, and the domestic Australian credit card 'Bankcard'. To operate the phone, you lift the handpiece and swipe your card. If the card is a debit card, you are prompted to enter your PIN. Then you must select the account you wish to charge: credit, savings or cheque account. The telephone then verifies the card, PIN, and looks up your current balance for cheque or savings accounts, showing you the funds you have available. Only then are you presented with a dial tone. Unfortunately, the minimum cost is $1.20 ($US1.00), so you have to make a LD call or 4 local calls ( 30c each, untimed ) for it to be worth it. Current call cost is displayed as the call progresses.

PT] What I do remember was the Bell Picturephone demonstration centers in major cities. Ours in Philadelphia was in the Franklin Institute a local science museum. There were two booths with first generation picturephones and a common phone outside, and two repeater monitors above the booths. The phones were sort of standard touch tone phones with ten buttons as normal (no * or # yet), but they also had an 11'th button, a P where the # is now. You pushed the P to make a picture call as the first digit. The two booths only talked to each other, but the common phone on the display was able to call about ten other demo centers, including Chicago and Wash. DC. I was hooked to the repeater monitors above the booths. It was all rather impressive for the early 1960's. At that time, it was expected that if you wanted to make a picture phone call, you would just dial P then the number, else 1 then the number for voice only. I don't know if the 1960's picturephone was 6MHz or 1Mhz like the version 2 system. In version 1, the camera was not directable down to a piece of paper, that was a later idea. All in all, the picture was very acceptable, little long distance noise at all, even on calls to Chicago. ===================================================================== Sydney S.

Our ATT System-25 at work doesn't have call > forwarding, it has what we've come to refer to as call following. We just installed a brand new System 25 here. It DOES have call forwarding AND following. I suggest you look into a software upgrade. The System 25's a nice improvement over our old ITT 3100. I won't restate the gripes about the new desk phones that are too light. Ours are the size of the old 500s, but they're empty, since the electro- mechanical innards have been replaced by silicon and such. The phone bottoms have LARGE cavities, since AT&T decided not to "enclose" the unused space; the bottom of the phone receeds up inside, if you follow. One can actually put the phone down ON TOP of paperweights, bottles of Liquid PaperTM, and such and hide things underneath! I personally haven't found a good use yet. TO THE System 25 DESIGNERS, if you're listening: ITEM 1 Our old ITT 3100 had a very non-Bell feature called "call park" which allowed you to park a call on one of several non-existant extensions. A bit more versatile than being reduced to transferring a call. The System 25 has call park, but you can only park onto YOUR extension number (called a "PDC"). Thus, single-line users can't park more than one call. Bit of a problem when you're trying to answer the night bell from a single line phone and you get a second call. The dedicated park extensions also had the benefit of allowing you to easily refer to them. E.g., since there might be ten of them, 160 through 169, you could page someone over the PA system and say simply "Call for Ken Shaby on Park Zero". With the S25, since ANY number may be a park, you have to be more specific ("Park One-Six-Zero"). And if the pagEE didn't realize the page was for him/her until late into the message (often the case), they may have only gotten the "Zero" which used to be fine; now they need the other two digits they missed. ITEM 2 Single-line phones can't do last-number-redial!!! That's gotta be only a software change, since multi-line phones can do it, I would think (as far as I know, all phones are handled by the same sort of card in the 25). They CAN do "camp-on-a-busy-line", but that only works for INTERNAL calls. I need redial on external calls BUT I LIKE THE SYSTEM 25. Don't get me wrong...

I live in Anchorage, but I used to live in Kenai, about 60 air miles south. Calls from Kenai to Anchorage, *night* rate, were about $6 an hour, last time I checked. Compare this with about $6.50 an hour to _Seattle_ from Kenai on GCI. GCI is collecting signatures now to get in-state competition on the ballot. Alascom accuses GCI of wanting to skim the heavy-traffic routes and leave the Bush under-serviced, but a GCI rep recently dismissed that allegation. "Give us half that AT&T subsidy you rarely mention, and we'll be happy to service the whole state." Indeed, since deregulation began to force interstate rates down, Alaska's in-state rates have risen! Only one in-state reduction, of only 2 or 3 percent, was ever made by Alascom, and that seemed to be in answer to a barrage of ads by GCI asking for permission to compete. The situation extends farther than telephone service. Alaskanet provides the state's only packet-switching access. Through Alaskanet, you can access Tymnet or Telenet. (Tymnet is transparent; Telenet needs a login sequence) This connection is, however, subject to a Gateway surcharge of 4 dollars an hour! Translation? Accessing any of the major services like CompuServe or PeopleLink ends up at full prime-time rates 24 hours a day. Also, we don't get PC Pursuit access, and I'm not sure I could get on StarLink from here. The single good deal in net access is Computer Connection, the Usenet node here.

Date: 14 Oct 89 06:13:34 GMT Organization: Computer Connection Last week, voters in Anchorage turned back an attempt by the Mayor to sell our telephone utility to Pacific Telecom. (Anchorage Telephone Utility is reported to be the last Muni-owned phone company in the U.S.) The publicity fight was intense, and pretty one-sided from PTI's 1 million dollar ad budget. As a result of debating the issue (I campaigned against the sale), I have had lots of requests for information. One of the possibilities raised was restructuring of rates and instituting measured service to gain an effective rate increase in the face of promises to hold the line. I'd like to get some input from the net... Do you have measured service? What are the actual rates? Do you have to juggle zones? Do you have a free-call area? If you were there for the beginning of measured service, what was the introduction like? (was there a public outcry? Was the public even consulted?) Anecdotes are welcome, too. Please e-mail to save bandwidth, and I'll summarize and send it to Patrick for consideration. For the record, PTI owns 62 local Alaskan wireline providers and Alascom, the state's only in-state long-distance company. One of the biggest arguments against the sale was that PTI (based in Vancouver, Washington) would have attained 80% ownership of Alaska's phone service. Roy M.

NTID was to be a showplace for visitors and government types to show what could as far as educating the deaf. Anyway we had about 20 locations on campus, both offices and public areas, that had picture phone installed. I didn't spend a lot of time experimenting with them but they were pretty interesting. They were removed around '79-'80 as I recall, mainly because of lack of use and maintenance problems. As I recall they were manufactured by Stromberg-Carlson but I could be very wrong about this.

Readers who have occasion to watch Mystery, Masterpiece Theatre, Nova, or This Old House (among others) may have noticed the "WGBH Boston" logo that precedes these programs.

They are audible right through the subscribes phone set. We have spent a good amount of time with various combinations of modems and metering pulse rates. With STD calls (pulses every few seconds), MNP modems seem to work. Without MNP, the error rates UUCP sees are quite high. For International ISD calls, even MNP modems fail to sychronise consistently. The rather loud clicks seem to affect the AGC, one can hear the modem monitor speaker "breathe" after each pulse. Also interesting to note is that the Trailblazer Telebit modems also fail to synchronise their PEP protocol with pulses as fast as 1/sec. The pulses coming every second interferes with their "fast-turnaround" which is about the same rate. We finally had to persuade our local phone authorities to find ways of giving us a pulse-free connection. We were fortunate, but not all smaller organizations might have been so.

I visited a telegraph office once, on a school field trip over thirty years ago, in a small city (about 17,000 and a university). My recollection is of the standard marble top counter with the pads and the machinery behind. One thing no one has mentioned is what I think was the standard form of a telegram in those days: the telegram was printed not on the form, but on a long strip of gummed paper. This was fed through a little dispenser (not unlike those sometimes used today for taping up boxes) which allowed the operator to simultaneously gum the strip and apply it to the form. It had a serrated tip so the operator could tear it at the right edge of the paper and start a new line below at the left. It is my recollection that telegrams were often prepared much the same way that we much later did Telexes: a paper tape was punched off line, then read through at speed (such as it was). This of course allowed the correction of errors. Telegrams had a feature (and may still for all I know) of repeating in a string all numeric words at the bottom of the telegram, including any figures in the body of the telegram as well as street addresses and postal zones in the header. Presumably this was done for reliability, since transmission or transcription errors are much less tolerable in numbers than in text. There has been some discussion of the 5-level teletypes. I played with a Telex machine for a time, though I had already had a lot of experience with paper tape on the 8-level Model 33 (as a minicomputer I/O device). As delete (then called rub-out, for good reason) was used in the ASCII devices to obliterate errors, since it was coded as all eight holes punched, LTRS, which had all five holes punched, was used on the Telex machine. This reset the device to its unshifted state, was otherwise a "no-op" character, and so was used as leader and trailer on a strip which contained a message. [There's a lot more that comes to mind on the topic of those mechanical beasts, but I'd better pass.] As an undergraduate, I too worked in a radio station which had Western Union clock service for the first couple years I was there. Our station also had the hourly signal wired through the control panel to an oscillator so it could cause a beep on the air if enabled (since we broadcast a lot of classical music, we didn't want it on all the time). It was a skill practiced by the announcers to "make beep" following any program that ended on the hour. In particular, one had to know exactly when beep would occur. The clock lost perhaps a half second an hour, so you knew beep would happen when the second hand was one and a half ticks away from the top; if you were going to make it, you could signal the controlman (we used a two person operation) who would push the button to enable beep. Then at just the right time, the red light on the clock would flash, the second hand would leap to the top of the clock and freeze there for a whole second, and the world would proceed as usual. If the WU line was down for a few hours, it became a little tricky to figure out at what second beep would come when it was restored, as the clock might be off a little by then. Then we came back one year, a bland white clock was on the wall, and beep passed into legend. ------------------------------ Date: Fri, 13 Oct 89 23:42:56 EST From: Ed Kern Subject: Re: AT&T as a "Backup" For US Sprint et al Reminds me of a call I made through ITT (10999) recently to 312/772-0347 (recently disconnected)... instead of getting the usual recording from Illinois Bell (like I would get using US Sprint or AT&T) I got a message telling me that "ITT is unable to complete my call to this number.

There was something even worse than the card dialers - a dialer imported from Germany that the Bell System briefly offered during the early 1960's. This dialer was called "Telerapid", and it had a capacity of 50 numbers. The programming was done by using a special wrench to remove a toothed-wheel having something like 125 teeth; there was one toothed-wheel per stored number. Using a special tool, teeth were cut out to leave only those teeth which corresponded to dial pulse line opens. This meant that cutting the toothed wheel also determined the interdigital timing interval! The operation of this dialer was totally mechanical and was actuated by selecting the desired number using a slider arm, and then pushing a lever; the toothed wheel therefore made a complete revolution in about 12 seconds. The first electronic dialer was the "Rapidial", and was offered during the early 1960's. Rapidial used a a writing tape backed by a magnetic tape which scrolled behind a window. The window would allow just one number to appear between two lines, and dialing was initiated by pressing a start bar. The dialing was stored through magnetic recording of a tone on the magnetic tape. A movable head operated by a motor scanned cross the magnetic tape to extract the digit pulses. The Rapidial contained a built-in rotary dial used solely for encoding pulses on new number entries. Rapidial was the size of a small Sherman Tank. :-) Actually, Rapidial was indeed HUGE, and occupied the surface area and volume of almost FOUR 500-type telephone sets! A few years later year came Son of Rapidial, more commonly known as Magicall. The Magicall dialer worked on the same principle was Rapidial, but it was considerably smaller. Making the small size possible was an external power supply and an external programming dial. Magicall had a small motor which rapidly moved the number tape in response to an UP/DOWN key. Even with this motorized drive, going from one end of a 1,000 number tape to the other took half a minute or more; it was really faster to look up the number in a book! The tape was "pre-alphabetized" and divided into sections of the alphabet whose size was determined by some joker's best guess as to the probability frequency distribution of the first letter of names. I don't remember how many numbers Rapidial could store, but Magicall came in two sizes: 400 and 1,000 numbers. The card dialer telephones were clever, but relatively useless. They came in both rotary and touch-tone versions, in addition to both single-line and 5-line keyset models. The Western Electric Touchamatic [tm] telephone ushered in the era of all-electronic repertory dialers and dialer/telephones. Compared to today's repertory dialer functions as implemented through integrated circuits and ESS or EPABX speedcalling, the above electromechanical dialers are extremely crude. I must confess, however, that in the past I had both Magicall dialers and card dialer telephones in different offices, and I felt pretty smug and state-of-the-art at the time while using them! :-) Times change, though, and now I have repertory dialing features out the wazoo. In my Grand Island office I have this fancy Northern Telecom SL-1 telephone with: (1) last-number re-dial; (2) "hot key" dedicated dialer key for a single number; (3) personal extension speed-dialing list; and (4) SL-1 system-wide speed-dialing list.

PT] I obtained the following file last year from CBBS #1. My thanks go to the uncredited author. ================================== Modem Noise Killer (alpha version) With this circuit diagram, some basic tools including a soldering iron, and four or five components from Radio Shack, you should be able to cut the noise/garbage that appears on your computer's screen. I started this project out of frustration at using a US Robotics 2400 baud modem and getting a fare amount of junk when connecting at that speed. Knowing that capacitors make good noise filters, I threw this together. This is very easy to build, however conditions may be different due to modem type, amount of line noise, old or new switching equipment (Bell's equipment), and on and on. So it may not work as well for you in every case. If it does work, or if you've managed to tweek it to your computer/modem setup I' d like to hear from you. I'd also appreciate any of you electronic wizzards out there wanting to offer any improvements. Let's make this work for everyone! Please read this entire message and see if you understand it before you begin. OK, what you'll need from Radio Shack: 1 #279-374 Modular line cord if you don't already have one. You won't need one if your phone has a modular plug in its base. $4.95 1 #279-420 Modular surface mount jack (4 or 6 conductor) $4.49 1 #271-1720 Potentiometer. This is a 5k audio taper variable resistor. $1.09 1 #272-1055 Capacitor. Any non-polarized 1.0 to 1.5 uf cap should do. Paper, Mylar, or metal film caps should be used, although #272-996 may work as well. (272-996 is a non-polarized electrolytic cap) $.79 1 100 ohm resistor - quarter or half watt. $.19 1 #279-357 Y-type or duplex modular connector. Don't buy this until you've read the section on connecting the Noise Killer below. (A, B,or C) $4.95 First off, open the modular block. You normally just pry them open with a screwdriver. Inside you'll find up to 6 wires. Very carefully cut out all but the green and red wires. The ones you'll be removing should be black, yellow, white, and blue. These wires won't be needed and may be in the way. So cut them as close to where they enter the plug as possible. The other end of these wires have a spade lug connector that is screwed into the plastic. Unscrew and remove that end of the wires as well. Now, you should have two wires left, green and red. Solder one end of the capacitor to the green wire. Solder the other end of the capacitor to the center lug of the potentiometer (there are three lugs on this critter). Solder one end of the resistor to the red wire. You may want to shorten the leads of the resistor first. Solder the other end of the resistor to either one of the remaining outside lugs of the potentiometer. Doesn't matter which. Now to wrap it up, make a hole in the lid of the mod block to stick the shaft of the potentiometer through. Don't make this hole dead center as the other parts may not fit into the body of the mod block if you do. See how things will fit in order to find where the hole will go. Well, now that you've got it built you'll need to test it. First twist the shaft on the potentiometer until it stops. You won't know which way to turn it until later. It doesn't matter which way now. You also need to determine where to plug the Noise Killer onto the telephone line. It can be done by one of several ways: A. If your modem has two modular plugs in back, connect the Noise Killer into one of them using a line cord. (a line cord is a straight cord that connects a phone to the wall outlet. Usually silver in color) B. If your phone is modular, you can unplug the cord from the back of it after you're on-line and plug the cord into the Noise Killer. C. You may have to buy a Y-type modular adaptor. Plug the adaptor into a wall outlet, plug the modem into one side and the Noise Killer into the other. Call a BBS that has known noise problems. After you've connected and garbage begins to appear, plug the Noise Killer into the phone line as described above. If you have turned the shaft on the potentiometer the wrong way you'll find out now. You may get a lot of garbage or even disconnected. If this happens, turn the shaft the other way until it stops and try again. If you don't notice much difference when you plug the Noise Killer in, that may be a good sign. Type in a few commands and look for garbage characters on the screen. If there still is, turn the shaft slowly until most of it is gone. If nothing seems to happen at all, turn the shaft slowly from one side to the other. You should get plenty of garbage or disconnected at some point. If you don't, reread this message to make sure you've connected it right. ***END OF ORIGNAL FILE*** ====================== ADDITION TO ORIGNAL FILE - 2/29/88 - Mike McCauley - CIS 71505,1173 First, a personal recomendation. _THIS WORKS!!!_ I have been plagued with noise at 2400 for some time. I went round and round with Ma Bell on it, and after they sent out several "repair persons" who were, to be kind, of limited help in the matter, I threw in the towel. I saw this file on a board up east a few days ago, and thought I'd bite. Threw the gismo together in about 10 minutes, took another five to adjust the pot for best results on my worst conection, and guess what? No more worst connecion! A few pointers: 1) The pot need not be either 5K or audio taper. I used a 10K 15 turn trim pot. Suggest you use what is handy. 2) I used 2MFD's of capacitance (two 1MFD's in parallel) Two R.S. p/n 272-1055 work fine. Remember that about 90 Volts will appear across red & green at ring, so the caps should be rated at 100VDC+. 3) I ended up with a final series resistance value (100 ohm + pot) of 2.75K. I speculate that one could probably use 2MFD and a fixed 2.7K resistor and do the job 90% of the time. The adjustment of the pot is not very critical. Changes of +/- 1K made little difference in the performance of the circuit. Hope it works as well for you as it did for me. Mike McCauley ============================== Second addition: 26 July 1989 The Noise Killer also works well for me. I own a Product R&D 2400 bps modem and have been irritated by noisy modem connections to Chinet and CBBS #1 for the past few years. Today, I went to a Radio Shack store and bought the parts for the Noise Killer for less than $4 dollars and built it in less than an hour. (I am a klutz with a soldering iron.) I used all the parts listed in the original message except for the modular surface mount jack. The Radio Shack store I visited did not have the jack, so I instead bought a #279-1261 Flexible Telephone Extension Cord for $1.20 (it was on sale). I already had the modular line cord and the Y-type modular phone adaptor, but I did not need to use the latter. Turning the stick of the 5k audio taper potentiometer counter-clockwise almost all the way made the connections to Chinet and CBBS #1 nearly noise-free. I continue to tune the noise filter. Parts list (not including modular phone cable) Cost #271-012 Two 100 ohm resistors (use only 1) 1/2 watt $0.19 #279-1261 Flexible Telephone Extension Cord 30 ft. $4.99 ($1.20) #271-1720 Audio taper potentiometer 5k ohms $1.09 #272-1055 1.0 MFD @200 volt metalized film capacitor $0.99 -Ed L edlee@chinet.chi.il.us ------------------------------ Date: Sat Oct 14 04:26:06 1989 From: Lang Zerner Subject: Re: Area Codes --> Locations Organization: The Great Escape, Inc I know a number at Bellcore which lets you key an area code and exchange, then speaks the location name using what sounds like a DECtalk speech synthesiser.

For those of you who think Caller ID is the worst scourge to ever come to the telephone industry, consider this case from Van Nuys, CA about three weeks ago: Penny and Michael Rodgers are a typical family living in Van Nuys. Their son Jameson is three years old. While Mr. Rodgers was gone to work one day, Mrs. Rodgers became violently ill and began choking. While the nature of her illness was not discussed in the newspaper account, what was noted was that she collapsed on the floor in the family's home, and was choking and gasping for air. Little Jameson saw his mother there and tried to talk to her. She would not, because she could not, answer him. But he knew what to do because his parents had taught him that in any dangerous situation; ie, if anyone tried to hurt him, or his parents; or if anything seemed to be wrong, he was to push the button on the autodialer connected to the phone which had the picture of the policeman. That, he was told, would summon the police and bring help. The autodialer was programmed to simply dial 911, which conneced to the Emergency Services dispatcher at the Van Nuys, CA, Police and Fire Department. Jameson lifted the receiver and pushed the button. He wasn't able to tell the lady who answered where he lived, and he did not know for sure how to say his last name. But he knew he was Jameson, three years old, and that his mother was laying on the floor and would not speak to him; and that she was coughing and 'breathing funny'. By using her Caller ID display, the emergency dispatcher was able to locate the phone number and address of Jameson and his mother. Once the ambulance and paramedics were enroute, the dispatcher asked Jameson to go outside and wait for them to arrive, then take them to his mother when they arrived, about two minutes later. The City of Van Nuys recommended a 'hero award' for little Jameson, and at a ceremony last week, the tape recording of his conversation with the emergency dispatcher was played back. Police officials pointed out there were two lessons to be learned from the experience: One, that all children should be taught, at the earliest possible age, how to summon emergency help over the telephone from '911'; and two, that without the Caller ID enhancement to the community's Emergency Service line, there would have been no way to get help to Mrs. Rodgers in time to save her life. He noted that prior to the installation of Caller ID, there had been several objections to the service; 'violation of privacy' being the major complaint. Some people apparently felt they had the 'right' to talk to the police anonymously, and that this 'right' superceded the rights of the police and fire departments to administer their duties effeciently and effectively. "We think caller ID was responsible for saving Mrs. Rodgers' life." Patrick Townson ------------------------------ From: "Gregory G. Woodbury" Subject: Info on ISDN Gateway Services? Reply-To: "Gregory G. Woodbury" Organization: Wolves Den UNIX BBS Date: Sun, 15 Oct 89 03:17:17 GMT I have been hearing that various RBOC's are investigating the gatewaying of ISDN service to information providers. To me this seems clearly a way of using the ISDN capabilities to provide direct access to services similar to Compu$erve or GEnie. I have also noted that the Hon Mr Green has prevented the phone companies from providing the information services themselves. Given that the phone co's are not doing this for free, and that the service providers are also out to make money (usually) does it seem reasonable to think that a "community electronic message service" (municipal EBBS) could become a "service provider" that could be gatewayed to? Or am I way off the mark and misunderstanding the gateways that are being discussed in relation to the phone companies? Gregory G.

That got me a local operator who instructed me to dial 00 to access AT&T. I explained that I *did* dial 00 and got her, not AT&T, so she tranferred me. The AT&T operator could not understand why I would be trying to place a calling card call through her, so I explained that I was at the airport and calling from a COCOT that would not accept 10288. She agreed to place the call but said she was surprised to hear of the problem because "they aren't supposed to block access anymore". Interesting. Jessup, MD - We're using ITT for LD in our office and have done so for about a month. Friday afternoon we received a call from ITT informing us that they recently bought/were bought by (?) a company with a 100% fiber optic network in place and that our service would be switched to that service in about a week. Does anyone know anything about this "merger"? Columbia, MD - I recently moved into a new apartment complex and found that only two pair had been run to the apartments (surprising in that this place was built in 1989!). Of course, the Network Interface is located in the next building in a utility closet, so I can't get C&P to run the extra pair for my third line. Does anyone know of a way to get three lines worth of service up to the apartment on two lines worth of wiring?

Levine" I can't say anything about the specific coordinate system that the V&H tapes use, but I can contribute something I learned in a cartography class a while ago. Using latitude and longitude to compute distances is not easy because lines of longitude are not parallel. One minute of longitude is longer in Miami than in Boston, so straightforward sqrt(x*x + y*y) formulae would tend to overcharge customers in the north and undercharge customers in the south. This is closely related to the problem of producing maps on flat pieces of paper. There are zillions of projections that cartographers have used to map the curved surface of the earth to a flat map. The most familar is the Mercator projection which preserves angles at the cost of severe area and distance distortion. There are also equal-area projections that distort angles so but make equal areas on the map correspond to equal areas on the surface of the earth. In a computer mapping project, I used the Albers equal area projection which is commonly used for maps of the 48 states; it has an origin in the Pacific, southwest of California, and distances measured in meters north and east of that point. Plotting X and Y map coordinates give a reasonable looking map since the projection has already been done. The V&H tape uses some other projection that I expect is intended to make equal distances equal. Any given projection is tuned to the area that it is intended to display; the Albers projection is tuned for the lower 48 and does not do very well for Alaska and Hawaii. I'd be interested to hear if V&H has some non-linear hack for Alaska and Hawaii, or if they figure that they're so far away from everything else that the projection errors are unlikely to put many calls in the wrong rate band.

I haven't seen an ADAS > installation in a good many years. My parents have a condo in Bethesda, Maryland (a Washington, DC suburb) in which ADAS was installed during the last year. At the same time it was installed, they were offered equal access, call-waiting, and several other custom-calling features. From the sound of things, I think they had number 5 crossbar switching until the time of great changes. It now sounds more like 5ESS. (Does anybody know for sure? It's 301-229 for the curious.) This may mean that the 5ESS supports ADAS. It may also be a CPE-based version of the same service. Perhaps the armored panel phone in the foyer detects the touch tone from the resident's set and unlocks the door? I don't remember seeing any brand name on the set. When I visit, the directions on the phone tell me to dial # and their appartment number. When I lift the handset, there is no battery or sound in the receiver. When I enter the #, I hear what sounds like CO dialtone. I then enter their three-digit appartment number, and hear the three touch-tones in the receiver. As soon as I have entered three digirts, the phone dials their 7-digit number, using pulse-dialing (I hear the pulses in the handset). The microphone is dead (i.e. no side-tone) until after dialing is complete, but is enabled during ringing. When they answer, they dial 9 to admit me. I hear the first few tens of milliseconds of their tone signal, and then silence. About 500 msec later, the entry door goes "thunk-buzzzzzz" and I am given access. Does anyone recognize this system?

Two major examples are Teleport-New York (TCNY) and Teleport-Boston (TCB), both members of the Teleport Communications Group (TCG). In both cases, fiber optic local loop networks have been constructed in New York and Boston which provide alternatives to the local exchange companies (New York Telephone and New England Telephone in these cases - both NYNEX companies). The TCG companies offer DS-0 (56/64 kbps), DS-1 (1.544 mbps) and DS-3 (45 mbps) services on their fiber systems serving business customers.

Teleports are useful, but have their problems when the sending and receiving stations are separated by large amounds of latitude, longitude, or altitude, due to conservation of momentum and/or energy. Systems which automatically compensate for these shifts are still under development. The definitive work on this subject is an essay by Larry Niven, "Theory and Practice of Teleportation", reprinted in the _All The Myriad Ways_ collection.
