A friend of mine on my hall was from The Philippines, and would have some people back there call the hall payphone COLLECT. This also worked for this guy who had relatives in Isreal. What they both did was have their "associates" go to a payphone in The Philipines or Isreal, and tell their LOCAL operator to make a collect call to US telephone number 203-346-99xx (forgot the payphone number...I was lucky enough to have my own phone!) The local operator in whatever country would call the payphone, WITHOUT an AT&T or SNET (local 'Bell' Operator). The people at my school on the other end would gladly accept the collect call, and they would talk for 20 minutes or so without any problem. I don't recall SNET ever coming to check out the phones or anything, but after a few months of this, they put in a Charge-A-Call on the hall, and took out the regular payphone. They also (apparently) programmed the switch to intercept all incoming calls to the Charge-A-Call (which is standard) so you could call collect, but would get "The number you have reached, 346-99xx, is not in service, for incoming calls". Being ever-so resourceful, I recall that they just had the calls placed to another payphone in the dining hall, but school ended for the year shortly thereafter, and SNET didn't change any more payphones around. (Incidentally, you can also do this with AOS outfits that have a pretty poor data-base of payphone numbers. They are SO glad to rip you off with a collect call that they don't spend too much time verifying if they can actually get some money from that number. You can even charge it collect to another COCOT! But who would want to wait around a slimy COCOT for a call? :-) Even more amazing is that recently I was using a COCOT (sorry everyone...) to make a calling card call. I wanted to see if they would bill me for a call to a number that is not in service. So I dialed in my calling card number, but while I was dialing I noticed that the "7" button was broken, and wouldn't generate the 7 tone. So I pressed a 8 instead and then a whole string of 8's because I figured it woudln't work anyhow. But it DID! The call went through on an INVALID card number! Now I got interested, and made up some card numbers in hick areas that I've been to. I tried 702-454-9950-1234. 702-454-9950 is not in service. Also, I don't know any calling card's with PINs of "1234". Guess what... It worked too! So I tried 702-454-9950-4321. Again, went through. I tried some number in 206 that I just made up. Worked fine! I said "This is ridiculous...someone could make up a PIN for *MY* number and bill me!" (well, doubtful I would be billed, but they may call me or something...). I tried a variation on my PIN, but it didn't work. So I suspect that they don't have a complete data base, and for less densely populated areas, or non-Bell areas, or (any suggestions?) they simply don't bother to check. I read it costs them about $.35 to verfiy a card (compared to $.07 for AT&T, which is one of the excuses they use in favor of their 500% surcharge) so maybe they figure it isn't worth it on cards from areas where there is less fraud? Sounds silly to me, but I guess they are so greedy they skip a bit on security here and there... Well, serves them right if you ask me...:-) -Doug DReuben%eagle.weslyn@Wesleyan.Bitnet DReuben@Eagle.Wesleyan.EDU (and just plain old DREUBEN to locals! :-) ) ------------------------------ From: Richard Edell Subject: Re: Automated Telephone Calls Date: 28 Apr 89 22:23:22 GMT Organization: University of California, Berkeley (student) In article menges@menges.cs.unc.edu (John Menges) writes: >I'm looking for a box to do the following: >- Initiate and receive voice telephone calls (one at a time is ok). >- Speak messages (from arbitrary text, not pre-recorded) well enough > for a small number of experienced users to understand.

(Sorry, couldn't cut much out of the original posting, so I decided to include it in its entirity) Digital Equipment Corporation sells two products, DECtalk and DECvoice. These may meet your requirements. DECtalk sits between a telephone line and an async port, sending status messages to the host computer for things like phone line ringing, DTMF received, etc. The host can send control commands for things like dial a phone number, hang-up, etc. The host can also send text to DECtalk and DECtalk will *READ* this text to the caller. Several voices are available and the speech is pretty good. You may call it for a demonstration at (508) 493-0645. Cost is about $4000 per port (phone line). DECvoice connects to a MircoVAX II. In addition to what DECtalk does, DECvoice is capable of speaker independent voice recognition (Yes & No, maybe more?) and of digitizing (recording in digital form) the caller's voice, saving this recording on disk, and playing the recorded voice at a later time. DECvoice requires VAX/VMX Version 5.0 - I don't know if this supports TCP-IP in the way you're thinking. I've called the demonstration number for DECvoice and the speech quality is better than that of DECtalk's but this is because they digitized (recorded) the speech you'll hear. DECvoice demonstration number is (508) 493-TALK. I don't know the price, but it sounds expensive. If you're interested you may contact DEC at (800) 832-6277.

But do you remember dividing-up your telephone bill with your roommates. This process allways seems to slow payment to the phone company, sometimes to the point where they mail a "reminder" notice. PROPOSED SOLUTION: "Roommate Billing": this service, when added to a phone line, requires that when a call is placed that a "user account" code be entered. The monthly bill is broken down by account code so there is no question about how much each roommate is to pay (monthly charges are separate). There is only one responsible person per phone line. POSSIBLE IMPLEMENTATIONS: For each valid "user account" code issued assign a fictitous billing number (I've seen these used for summary billing, business calling cards -- they're 10 digit numbers w/o valid area codes/NXXs i.e. (758) 151-xxxx). This allows long distance companies to continue with regular ANI for billing. - or - Add this account code to all calling records - UCK! I figure this type of service would be worth a few bucks/month ($3-$5) to the numorous student-type households. Of course there is always the alternative of several phone lines/households but the idea is to avoid this additional expenses. What do you think? Richard J.

C. Berkeley Patrick- Thanks very much for this posting. I have two questions that perhaps you can answer for me. You say that MCI not offering their new plan to people who are casual callers yet they are not processing changeover orders to the BOCs but instead having the customer do that themself. My question is then: How do they know who is a casual caller and who is not? My local service is provided by Pacific Bell. It is my understanding that the switching for the long distance carrier is done at Pacific Bells Tandom switch. Unless casual caller calls are sent to MCI on different trunk groups I don't see how MCI can tell the difference. In other words can't I just tell MCI that I've elected to have them as my default carrier and still take advantage of the program? Please excuse my naivite. I know that I only have enough knowledge about the system to hurt myself. I'd also be interested in knowing if MCI will be getting intrastate tariffs for this program here in California.

I found out from two of the three that in fact you do have to permit MCI to notify the local telco; meaning of course even if you do not cut yourself over to MCI for dial one plus, they will do it anyway. All three people did agree that the new service was only for one plus customers. The third person I spoke with said if I wanted to call the telco myself, it would be cut over faster than waiting for the paperwork from MCI to be processed. But, he said indeed, they would follow up and verify it 'was done correctly'. PT] ------------------------------ Date: Sat, 29 Apr 89 21:44:25 EDT From: "Samuel E.

(such as from Trenton, NJ to Morrisville, Pa.) From what I saw, or read into, the articles that appeared in both the Newark Star-Ledger and the (Plainfield-Somerville) Courier News, in order to free up some additional central office codes, seven digit dialing across area codes will be eliminated. As I understood it, there are some boundary areas where currently area codes aren't needed, although the number is in a different area code. What this does, of course, is prevent that central office code from being used in the other area (i.e., a central office code in Stroudsburg, PA cannot be used in 201). The article said that eliminating this short-cut dialing will free up about 25 central office codes. We'll probably see more details when the official announcement is supposed to be made (Monday, May 1), but, according the article, this shouldn't affect local calling areas or LATA boundaries. My central office will be affected by this; according to the map, the Summit, NJ central office will be in 908, however our local calling area includes Millburn, South Orange, Chatham, Livingston, and Madison, which will remain in 201. -- Stan Krieger Summit NJ ------------------------------ Date: 29 Apr 89 15:41:37 GMT From: Keith Brazington From: keith@g4lzv.co.uk (Keith Brazington) Subject: Re: New area codes for London UK.

However, most of the other exchanges are VERY old....rings that sound like an idling car engine, "growl" dialtones, etc. In fact, I was in a restaurant nearby, and the phone rang long-short on each cycle. Must be (or must have been) a party line. The number we have is NOT a party line, at least not now.

One small PBX unit I used for several years is ideal for persons with a large residence or a small business. The MELCO SYSTEM 212 is a neat little switch that would meet the needs of many, if not most large residences. Melco is located out in Washington State; I think possibly in Bellview (?), but I no longer have the documentation on this unit. When I moved a few years ago to my present apartment (about two blocks from my former home), I sold the Melco unit to someone else. This was about the time we were getting ESS in our CO anyway. The Melco System 212 has two CO lines and 12 internal extensions. The extensions are numbered 21 through 32. The Operator zero is an alternative address for extension 21. Any extension can dial 9 for an outside line. Dialing 81 or 82 picks a specific outside line. The extensions can dial each other, of course, and if you have a paging system hooked in, dialing 4 connects you to the amplifier and keys up the microphone circuit. Any CO call, incoming or outgoing, can be transferred between extensions by flashing and dialing the desired two digit code. Incoming calls default to extensions 21 and 22, but can be either 'call forwarded' to ring on any desired extensions, or they can be answered using universal answer, which is 7. A common audible circuit allows up to five electronic chirpers or up to three conventional bells to be located in stategic locations. Individual extensions can be made busy by dialing 39, and will stay busied out until they go off hook again. The two incoming lines can individually be silenced by dialing 61 or 62. Dialing 63 silences the common audible while allowing the phones assigned to answer incoming calls to continue to ring. Dialing 64 cancels all prior suspensions on the incoming lines. Calls can be put on hold by flashing, then hanging up. A time out can be set for one minute or five minutes, and calls left on hold longer than that time will ring back to the phone which put them on hold. Music on hold is available. Calls can be 'parked' at another extension by dialing 60 and the desired extension number; then retrieved from that extension within the time allowed for hold. The whole unit weighs about ten pounds, is in a plastic case and easily mounts on the wall at the point where the incoming CO lines enter your premises. It runs on 110 AC, and a battery backup is of course suggested but not mandatory. In the case of power failure, incoming calls are routed to extensions 21 and 22, which can also make direct outside calls while the power is off. The loop between an extension and the switch can be quite long. In my application, the switch was located on first floor of the building, in an old, large wooden cabinet from Bell which at one point years before had serviced a switchboard. I used all existing house pairs, and the most distant extension was on the 9th floor, about 150 feet away. However, one purchaser of the unit, according to Melco, was a company which did oil exploration work in Alaska; they had several loops that were better than five miles from the switch and the reliability was excellent. I bought the unit for $700 back about 1980. The first one flaked out on me about six months after I had it and Melco sent a replacement by air express the same day. I did find it was very sensitive to dirty power, and it had to be grounded properly, otherwise it would *appear* to work but get its brains scrambled about once a week and require me or someone to go to the switch, power down and come up again. Since it uses the switchhook flash for its own purposes it is NOT compatible with call-waiting or three way calling, unless you do as I did, and make a quick and dirty patch: I ran a second, 'control pair' to each station, and mounted a little micro push button on each phone. That pair by-passed the Melco and went into the CO lines before they entered my switch. Pressing the contact *very briefly* (like half a second) would trigger the CO switchhook features while still convincing the Melco the CO had not disconnected (therefore it would disconnect me!). But that was cumbersome and unreliable at best. I'd say don't plan to use custom calling features with it except for speed dial. And I did not even really need that since I had a Demon Dialer in series with the two CO lines, again between where the CO came in and where Melco took over. It did a quite adequate job for me prior to Starline being available. One drawback was it only had one talking path for internal station to station calls, and two talk paths for CO calls. If two stations were talking to each other, a third station could not initiate another internal call at the same time. Likewise, just one dial tone. Whoever had it used it. Other extensions off hook waited for dial tone if someone else had it first. If a phone went off hook and did nothing, after ten seconds of dial tone there would be ten seconds of error tone, and that phone would be yanked out of the system, to free up the limited facilities available.

The monthly > bill is broken down by account code so there is no question about how much > each roommate is to pay (monthly charges are separate). There is only one > responsible person per phone line. OHH YES! Having been the official "phone bill figurer-outer" wherever I've lived at college, I couldn't agree more. I've occasionally thought about how nice such a service would be. (Think: 6-10 students sharing one phone line.) My imagination has included the further possibility of the "responsible person" whose name is on the bill, being able to temporarily disconnect someone's access number if they aren't paying their bills. Students are often nervous about having the phone bill in their own name because of the possibility of getting stuck being responsible for a lot of someone else's calls. Unlike above, though, the way I've envisioned Roomate Billing working is that local calls go through normally, but any 1+ or 0+ call would require an access number be entered. Roomate Billing would certainly make figuring out shared bills easier. It would also have the added benefit of preventing dormitory interlopers from making long-distance calls on such a line, and that's something which seems to happen to a lot of people. Haven't we all heard those stories about the "two 40 minute calls to Tasmania which showed up over Winter vacation?" The problems I envisioned putting this into practice had to do with collect and operator-assisted calls. How might one block an interloper from making a person-person call, and how might one deal with billing collect calls? =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= /------------------------------\ Ken Selling | The Scholar on the Schwinn | \------------------------------/ Organization: Wesleyan University Internet: kselling@eagle.wesleyan.edu BITNET: kselling%eagle@wesleyan.bitnet Local: :-) kselling =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= ------------------------------ Subject: AT&T 7404D phone info requested Date: Mon, 01 May 89 17:02:30 PDT From: Doug Claar We have 7404D phones on our site.

Just a point of clarification here. The Around Town feature, while it may allow local calling with out a surcharge, is not intended for this use. the intention is that you will make long distance calls out of the service area of the local Telco (or BOC). What the Around Town feature will do is not add a surcharge to any calls that are made using it, if those calls are made within the area that is a local call from the phone number that that card is tied to for instance if my number is 123-456-7890 and 123-555-1234 is a local call for me then if I make a call with my MCI calling card from 123-555-1234 there will be no surcharge added to the call.

If you live in any version of ESS with any version of generic, you can have 10xxx dialing. You may live in an 5XB machine. These often have "precise tone-plants". To get 10xxx dialing requires the addition of a beastie called an "Adjunct Frame". I don't recall who makes these, but they fit somewhere in the line-link frame (logically, not physically) and generate precise dialtone. You can tell if you're on one of these by the following test: Get a dialtone ... dial "#" ... if you hear a "different" dialtone, you've got adjunct dialing. This allows 10xxx dialing. If you are served out of an electronic toll-tandem (most of the US is) then you can get presubscription. (Even people on #1 SXS machines can get presubscription if they're served by DMS-200 Tandems.) Summary: 1) ESS always allows 10xxx, unless specifically disabled. 2) 5XB sometimes sounds like ESS 3) 5XB can be upgraded to allow 10xx Oh, one more thing: ESS 5 allows party lines, with distinctive ringing. These machines are marketed heavily to small areas, as replacement for old step machines. Many customers will want to keep their old party-line service, so the machine allows it. As a side-note, this is how distinctive ringing service is implemented for the "many-phone-numbers-on-one-phone-line" feature. (Often marketed as "room-mate service" or some-such.

Goldstein dtn226-7388" Date: 1 May 89 10:18 Subject: re: Mass. phone rates Noticing JSol's message, I tried to call the NETel newsline, but it was out of order! Having followed tariffs for over a decade, though, I can comment on what's likely to happen. NETel last got a "general rate increase" around 1983, and its rate structure hasn't been examined in a lot longer. The 1983 round raised some private line rates by a lot (short hauls), lowered long-haul private lines a little, and otherwise was across-the-board by a few percent. Since then, the area has grown quite a bit. Business for NET has been excellent. So it's unlikely that they're really hurting. Sometimes telcos keep quiet about their rates since their rate of return has gone up as a result of growth and they don't want the reguators to lower the rates to the legal levels! NET may have been in that position, and it's possible that they're just now getting back into the range of lower profitability. In any case, there's no reason to expect the Mass. DPU to let NET impose residential message rates where Metro service is now available. Politics are too important, and it would be too easy to shoot down the change as being unjustified. Some changes are not unlikely, since the Metro boundaries were set in 1908 (!) and Boston has, well, grown a bit (suburb-wise) since then. Lynn, btw, is an illustration of a case where 7-digit dialing doesn't mean "local". Lynn subtends Cambridge toll, so it's wired up as part of Metro (hence the 7-digit dialing), but it wasn't put within the 1908 boundaries so it is treated differently. Saugus (just west) is another such case, surrounded by metro but not included. It's local to areas that would otherwise be 1 message unit (8 mile radius) and toll (not 2MU) to the rest of Metro Boston. fred ------------------------------ End of TELECOM Digest V9 #154 *****************************   Date: Wed, 3 May 89 1:47:11 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest V9 #155 Message-ID: <8905030147.aa32247@delta.eecs.nwu.edu> TELECOM Digest Wed, 3 May 89 00:45:46 CDT Volume 9 : Issue 155 Today's Topics: Moderator: Patrick Townson Loud Hum on the Phone (Jeff Russ) Re: Finding Your Own Phone Number (Gregory G.

You dialed your number direct and a GTE operator would ask for your card number. You gave it to her and got the direct dial rate with no surcharges.

Why was this stuff posted so early? Shouldn't you have waited until you got the inevitable reaction from AT&T and/or Sprint? Also, if you're going to describe the AT&T Reach Out America Plan, you should include the Evening and Daytime options which can be purchased for approximately an additional $1.00 per month each. The Evening option allows 15% discount on evening calls (5 p.m. - 10 p.m.). The Daytime option gets you a 5% discount on day calls. These discounts are subject to change. Notably, I know that the 15% discount is expected to change to 20% under new filings. Also, other rates are expected to change, possibly including the hourly charge.

AT&T Plans Michael Chin, in the previous message, questions my comments last weekend regarding the new MCI Long Distance plan for residence subscribers. He asks, 'why was this posted so early?' What is 'too early' about an announcement in a press release sent out on Thursday, April 27, with a request that it be distributed over the weekend of April 28-30 for a program which takes effect on May 1? I think the timing was about right. If Mr. Chin's question is why did *I* announce it 'so early' without waiting for responses from AT&T/Sprint, I would have to ask a counter question of my own to him: Why would either of those organizations bother replying if the media did not first announce this new program? Is Mr. Chin suggesting that the [Wall Street Journal], the [New York Times], and the [Chicago Tribune] -- to just name three papers I read each day -- should print the press release but [TELECOM Digest] should not have printed it? If he thinks I should not print news releases sent to me by phone companies and others, then someone should tell his employer to not send me so much stuff! Apparently both MCI Communications Corp. and his employer think I should talk about them as often as they can convince me to do so, if the volume of printed press releases, etc is of any significance. Not to worry, Mr. Chin! I'm sure AT&T will have something for me on the subject before long! They always do..... Then Mr. Chin says if I am going to mention the AT&T Reach Out Plans, I should do so accurately and completely. Aside from the fact that there are nearly a hundred such 'plans', i.e. one for each state for intrastate purposes; one for each state for interstate purposes, with many being in common to the others, the purpose of the original message was not so much to re-hash AT&T's long distance calling plan as it was to announce a new one and highlight what I believed was the major difference in the two; namely the additional evening time available. Mr. Chin points out that by paying extra to AT&T, one can get an additional fifteen percent discount on evening calls. This is true, however MCI's new plan charges *nothing extra* for the evening hours, and gives the overnight rate -- not just 'an additional fifteen percent discount', but with long distance calls now just costing pennies per minute anyway, this is not really a major point. Likewise, by paying extra to AT&T, one gets a five percent discount on daytime calls, meaning that you pay extra to AT&T to get daytime rates roughly equal to what MCI charges during the day for nothing extra. Even that does not hold true everywhere however! Here in Illinois, our 'Reach Out Illinois' Plan includes something called 'interstate transparency', which for 85 cents per month extra technically allows interstate calling on the intrastate plan. If you have this, as I do, you *cannot* also have the five percent daytime discount at present, because of technical difficulties in billing intrastate/interstate calls and giving the five percent discount which they are not permitted to do on intrastate (within Illinois at least) calls. AT&T also allows you to pay $2 extra per month on Reach Out America and have your Calling Card/Call Me card calls billed at Reach Out rates during the plan hours. So everywhere we look with residential bulk calling and AT&T, we find an extra surcharge in place for some added feature. That's okay with me, Mr. Chin, since I have always believed in paying extra to get the quality I want. You don't have to convince *me* to default all my calls to the Mother Company. Mr. Chin says AT&T will soon be lowering their rates. He believes I should have said nothing about MCI's plan until AT&T had their new promotion in place. That's tough. When AT&T sends me their latest news, just ask any of the readers here: I will give it space, and catch the devil from a few who think I praise AT&T too highly. By the by, Sprint *has* already responded: They announced their rates were reduced an average of 4.1 percent also as of May 1. See? I give everyone equal time here, Mr. Chin. Sprint did not announce a bulk purchase plan as such, but did cut their rates so that the price still comes out about the same as MCI's new rates.

MCI has something similar. You can use your calling card or else call collect. I found a little booklet in a hotel room over the weekend that has a surprisingly long list of numbers that work the other way. Here they are. Before you call them, consider that if you call Korea Direct's number, you will in all likelihood get an operator who speaks only Korean, and who can only complete calls to Korea.

Well, it looks like more changes to the Canadian telecommunications system are imminent. This item is taken from the Kitchener-Waterloo Record of May 2, 1989: ======================================================================== TORONTO (CP) -- The federal telecommunications watchdog has ruled on the side of competition in the supplying of private-line telephone service. A ruling Monday by the Canadian Radio-television and Telecommunications Commission will force Bell Canada, British Columbia Telephone Co. and Amdahl Canada Ltd. to lose their monopoly over the supply of equipment for the Dataroute service. Dataroute is a long-established service used by medium-sized and large corporations for a variety of functions, including banking, travel reservations, stock trading and lotteries. The service works within the confines of a company, unlike public services, which are available to all. The CRTC gave Bell and B.C. Tel until July 31 to release previously confidential signalling information that will allow manufacturers other than Toronto-based Amdahl to supply what is known as digital channel terminating equipment. This equipment, with related pieces, codes and decodes data and connects a corporation's private lines to the public telephone system. The issue of private-line services was brought before the CRTC by Paradyne Canada Ltd., part of AT&T. Paradyne first went before the CRTC a year ago. That company argued the existing arrangement gave Bell and Amdahl an unfair advantage, and that Dataroute customers would benefit from the introduction of competition into that market. -- Gerry Wheeler Phone: (519)884-2251 Mortice Kern Systems Inc.

Two things going on which do not bode well, but both will probably get cured eventually, and one probably already has been cured. This week, the site used to prepare and mail [TELECOM Digest] is switching machines. In the past we were on a machine called 'gamma' at eecs.nwu.edu. That machine is being removed from service, and I am now on a similar machine called 'delta'. This is transparent to you, the reader, since all mail merely comes to eecs.nwu.edu anyway. Pointers were, until yesterday, pointing at gamma, which in turn might send mail to 'alpha' or other places at Northwestern. During the change over Wednesday, it is possible some mail did not reach me. I say this because the mailbox was suspiciously devoid of new mail, and I found some new mail left behind at gamma. If you sent mail Tuesday or Wednesday and wound up getting it bounced back then I suggest you resend it to me. Our address is still 'telecom@eecs.nwu.edu' but there may have been some funny business Wednesday. For next: Since last week, copies of the Digest have not been making it through to the Usenet gateway for some reason. Some issues have been retransmitted three times, and are still being gobbled up in a black hole of some sort between here and chip@vector. My own control copies of the Digest are only sporadically making it through to my mailbox at chinet, a mere five miles away from Northwestern! Once I am able to re-establish contact with chip then our Usenet readers will again be getting the Digest. Since much of the correspondence from day to day in the Digest comes from Usenet readers, and they mostly haven't gotten anything for several days now, that explains why the mail is skimpy today.

Jongsma) ---------------------------------------------------------------------- Date: Sun, 7 May 89 21:05:39 CDT From: TELECOM Moderator Subject: We Are Back On Line! Last week was 'the week that was' here at TELECOM Digest headquarters. The machine we had been using to produce each issue of the digest (gamma) is being taken out of service, and replaced by a machine called 'delta'. Needless to say, nothing ever goes off without a hitch. We issued Digest #155 on Monday last week, and #156 on Tuesday, only to find on Wednesday that neither issue, #155 or #156, had made it out of the computer room, let alone getting to the subscribers. The dilemma, as it turns out, and if I correctly understand what Postmaster Gore was telling me is that the list channel worked fine on 'gamma', but had some serious problems relating to 'delta', and the 4.2 software it is running, until 4.3 becomes available to us sometime in the near future. Nothing would work to get the Digest out. No amount of pushing by hand did any good. It just wouldn't leave. Certain other systems, like bu-cs.bu.edu, where the archives are stored would hang up on us as soon as a call was made. No attempt was even made to mail out digests Wednesday, Thursday or Friday. Saturday afternoon a 'real expert' looked into the matter and provided some patches which would work in the interim. These patches consisted mainly of putting the list channel back on gamma -- where it had always been before, and where it had worked fine -- and tricking the mailer handling the Digest into going over to gamma and then out. Even those patches did not work exactly right, which is why some of you got three issues of 155 and 156 delivered during the day Sunday. But we *think* everything is in place now, at least until the Encore people supply Postmaster Gore with what he wants to do the job right. And I guess the 4.3 software is on the way also -- one of these days. That is why your last Digests arrived about a week ago until you got the two issues (and multiple copies of same) sometime Sunday. As jsol always tells me, mailers are fun! It's a new week, virtually a new month, and spring is here. Let's try again! Patrick Townson ------------------------------ Date: Sun, 7 May 89 21:56:19 CDT From: TELECOM Moderator Subject: One Year Ago: The Great Fire As Mother's Day approaches, one cannot help but be reminded of flowers, and fires, and telephones that work. Last year, the national center for FTD operations, which is located in Du Page County, Illinois, processed more than one million orders for Mother's Day flowers in the week before May 8. Then on Sunday, May 8, 1988 -- Mother's Day -- amidst a record volume of phone traffic even for that special day each year came what has come to be known as 'the world's worst telecommunications disaster' when fire struck Illinois Bell's 'Hinsdale Superswitcher'. Not being able to get the bills out to the florists for the Mother's Day flowers for several weeks caused much financial stress, but had the fire occurred a week earlier, with 250,000 orders in the FTD computer at any one time, the confusion would have been even worse. Imagine all the mothers who would have 'been certain' that their kids had forgotten all about them. Even the lost phone calls that Sunday afternoon a year ago left more than a few mothers miffed until word began spreading around the world -- just hours later -- of the terrible tragedy which had struck. It was shortly after 4 PM on that Sunday a year ago that an electrical fire started in the two-story, red brick building building in Hinsdale -- a building which looks like a thousand other phone company buildings across the United States. Neither Illinois Bell, long distance carriers, state or local officials would know for more than a day the extent of the damage. The 10 PM news on television that Sunday night showed the fire in progress, but had very little to say. The Monday papers printed a few paragraphs, but no one -- not even the employees at Hinsdale -- had any grasp of the extreme amount of damage they would find when they were permitted by the Fire Department to re-enter the building for the first time about 4:00 AM Monday morning; nearly twelve hours after the fire started. Miles of melted optic fiber; circuit boards twisted into bizarre shapes from the intense heat; extensive water damage to the main switch, with corrosion already starting; the offices totally gutted leaving not a single printed document to be used for reference in the days ahead. And where to begin restoring service? Not only did Hinsdale provide local phone service to several communities west of Chicago, but it provided cellular phone service for all of area 312. It was a long distance hub for all of northern Illinois. It also was the center for all communications traffic between the air traffic controllers at Ohare Airport and the Federal Aviation Administration control center in Aurora -- with links to Midway Airport as well. The first order of business was to restore the air controller's links, and these were back in service by late Monday evening; a few hours after workers were able to get into the building. Next came police, fire and other such emergency services throughout the west suburban area. By mid-day Tuesday, all police and fire departments in the area had at least one or two working phone lines. Then came area hospitals and other local government, again with just a phone or two. Cellular service, along with pagers were back in service Wednesday. Emergency phone service, in the form of trailers set up in various parts of the region were available beginning Thursday. There were *so many* vital emergency restorations all going on at once! Long distance phone service was re-routed around Hinsdale for nearly two weeks. Some local phone service became available about two weeks after the fire, and by a month later in early June, 85 percent of the restoration was finished. Was there anyone who did not at least have some inconvenience due to the fire? The most immediate impact was on business places with local service in the area who relied heavily on their phone service. Some of those companies shut down for three weeks. A few went out of business entirely. Calls between Chicago and the western suburbs were delayed or impossible to complete for at least a week after the fire. Of course, calls to Hinsdale were impossible for most of the month. James Eibel, vice president of operations for Illinois Bell pointed out, "We have had two fires in 104 years. I will never say never, but we have done everything possible to see that such a tragedy never occurs again." Eibel noted that an $80 million, five year plan to redesign its entire hub system in northern Illinois is underway, and on schedule. The new arrangement, when complete, will have each of the more than 100 phone offices here connected in parallel with at least one other office, any of which will be able to handle all the traffic from any office which shuts down for whatever reason. Illinois Bell has repeatedly declined to give cost estimates on the entire impact of the fire. But besides the $80 million redesign plan, new equipment was required at Hinsdale, which has been estimated at $20 million by telecom experts. And industry analysts claim that the company lost about $1 million per day in business during the period. "Illinois Bell believes this is the cost of doing business," Eibel said in an interview. "We foresee no rate increase at this time. After all, the company's capital investment budget is $600 million per year, and the $80 million in five years during the implementation of the new design can easily be worked in." Eibel also pointed out that the previously unmanned switching centers are now staffed around the clock, and that specialized training has been going on for some time. Other telcos have noted the 'Hinsdale experience' and changed their thinking on many disaster related issues also. "We did not ask to be placed in this position, but now we plan on being the leader in all areas. We are leading a change in the philosophy and attitudes held by many telcos. I can't afford to sit back and let someone else do it in the future. We are firmly committed to never again having something like this happen," concluded Eibel. Never again? Those are strong words. But if any good at all has come from the Hinsdale disaster a year ago this week, it is that Illinois Bell's telephone network is becoming stronger and more secure than ever against natural disasters of the sort that shook everyone with a rude awakening on May 8, 1988. Hey, New York Tel/PacBell/Southwestern Bell, et al -- are you reading this? You *do* remember Hinsdale, don't you?

Consumer Reports had indicated that readers had complained of failures of machines that had been "check-rated" (highly recommended). One of the problems they reported was that callers would be cut off while still speaking. I am now excountering this problem. With the machine in VOX (record-'til-caller-stops-talking) mode, the caller is cut off after speaking for anywhere from 5 to 20 seconds. I double-checked that the CPC feature, which apparently allows use of a telco- generated termination tone, is off. Has anyone else encountered this failure with PhoneMate machines? I plan to call their 800 number tonight, but was hoping comments from other users. I have never had trouble with Panasonic machines. I keep buying up to the new features and passing on the older machines. If this PhoneMate gives me anymore grief I will return it and buy another Panasonic. -Jim.

It seems that they are about to implement a form of the automated operator services some of the COCOTs have been using for collect and third party billing. According to the flyer, if you are making a 0+ call withing the LATA and do not enter a credit card number after the "bong", you may get connected to a computer asking you to touch a number corresponding to your billing request (collect or third party). You will then be asked to record your name. The called or billed number will then be called, a computer generated message will be played with your name inserted appropriately, and the receiver asked to touch a number corresponding to whether or not they accept charges. I tried it this evening a got a real operator, so I can't give any more details right now or comment on the possibility of spoofing the system.

This is only true sometimes. If you live outside of the metro calling area and have "Metropolitan" calling (as I do), Lynn and Burlington are toll calls. This seems to be the case for some other areas as well (like Hyde Park). Dorchester and Mattapan get free calls to Lynn, but not to Burlington. Swampscott, Nahant, Scituate, and North Reading are shown in the metro phone books, but appear to be toll calls for most people with metro service.

After several hours of busy signals, I managed to get through to the toll-free help line listed in the owner's manual. After asking about Call Waiting (I don't have it), CPC (I had it turned off), and callers pausing for more than a second (I tested it myself by counting the seconds aloud until I was cut off), the woman told me to take the machine to a local service center. Taking a brand-new machine to a service center is a bit much, so I returned the machine to the store with description of my experience. It is my suspicion that the machine simply has a problem with the threshold used for detecting speech. I could probably include instructions in the outgoing message to speak loudly, but doesn't inspire confidence, and doesn't work for faint long-distance calls. Since the problem with callers being cut off was noted in Consumer Reports in two earlier series of machines, I expect that this is a problem that won't be designed out soon. I would advise purchasers to bear my experience, and the Consumer Reports data, in mind when considering PhoneMate products. Neat features don't compensate for poor performance. By the way, a friend had similar trouble with an earlier model, so this experience was not entirely surprising. I have switched to a Panasonic with similar features. As noted in my earlier message, my experience with Panasonic answering machines has been consistently positive. Good thing I have friends and relatives willing to adopt the old ones :-). -Jim.

With the machine in VOX (record-'til-caller-stops-talking) Not with PhoneMate machines, but with Sanyo machines. Mine was a TAS-450, not a cheap little bugger, and it would hang up also between 5 and 20 seconds. Our outgoing message said "Shout so you don't get cut off," but that didn't help much. I sent a letter to Sanyo, and they said that their machine was a "quality product," and I obviously got a defective one. I sent it in along with $10 worth of postage, and got it back even more broken then before. The machine not only cut callers off, but almost never recognized touch tones for remote operation, had randomly blinking LEDs, would often lose messages instead of saving them -- it was just a piece of crap. I sent another letter to Sanyo, and threaten them with exposure on the net, among other places. They told me to try replacing my batteries again. (Didn't work.) My machine was not defective, I think, but designed wrong. Would it be too difficult to inlcude a VOX sensitivity adjustment with these things? (Mine didn't have one inside or out.) I hope you can return your PhoneMate; I doubt it can be repaired. I bought a Code-a-Phone, and am reasonably pleased with it. I lost a lot of money on the Sanyo, and got a lot of grief. I hope you folks consider not purchasing Sanyo business products, and *especially* stay away from the TAS-450 and the TAS-250.

The long distance company can't tell (nor should they care!) whether the call was dialed by a modem or by voice (it's identical).

But what it came down to is that it seems a person either needs a college education, or a lawyer present, just to make a phone call. The situation is simple. My daughter's high school band is performing in a show in Virginia Beach on Saturday (4/29); they left NJ today. If for any reason she needs to call me, I gave her instructions on how to put the call on my calling card (I believe it's cheaper than calling collect), but here is what I had to warn her about- 1. The "correct" number to dial, or push, is 10288-0-(201) and my phone number. 2. Don't use the phone in the hotel room, because it might not support 10XXX dialing, or worse, an operator may just identify him/herself as AT&T because of the code. Also, even if the hotel's LD carrier is AT&T, she may find the hotel will charge her for using the room phone, although the call wasn't billed to the room. 3. If she uses a public phone, use one that's owned by C&P Telephone. A private pay-phone, like one in the hotel, might not support 10XXX, or as above, the operator may see the 10288 and lie. And, even if you use a Bell phone, push the 10288 anyway. 4. Listen for the "Thank you for using AT&T" after she punches in my calling card number. But I also had to warn her that an alternate carrier name might not be obvious. She said, "So if it says Sprint, I should hang up." I said yes, but it could be a similar sounding name like "NPT", or it may just say "Thank you". Now, these instructions are to a high school junior who is in the top 25% of her class, and even with them, she could still get caught using a phone carrier not of her own choosing, simply because of all the permutations involved. To many people, it may look like you can get better odds from an Atlantic City slot machine than from a public phone. It used to be that all we had to do was teach our kids to dial "0" in case of fire or if the police were needed, but now that might not work either.

Frequently, after it rained, I got a loud hum, or no signal at all (just dead, although Touch Tones worked), and callers calling in to me got either a busy signal or the line picked up, AUTOMATICALLY, without me lifting the phone. After a while, I found out that it was a junction box outside my house, where my lines were connected to a larger pool of wires from the central office (?). When it rained, water got in there, and stayed there for a few days until it dried out. The water would ocassionally short-out my line, almost as if someone had "picked-up" the phone and left it off-hook, hence the apparent lack of a dial tone yet enough line current to power the Tone pad. It also explains why it was busy for incoming callers. At other times, there was a dial tone, but a very loud buzzing on the line. Incoming callers would get a very short ring, and then, (I am guessing now) after a certain threshold was reached, the exchange thought that the short circuit was actually me picking up, and connected the incoming caller and started billing. Some times it buzzed quite loudly, others not quite so, yet it happened regularly after a heavy rain. I told the lineman all the details, and he immediately knew what to do: He drilled a few holes in the bottom of the box for drainage, pasted up the top of it to stop water from entering the box, and moved my line which was having trouble a bit further to the top of the box so that if any water accumulated near the bottom in the future it would affect my line. I'm not sure you are having the same problem, but it does seem rain related, so maybe you have some exposed contacts outside that would tend to collect rain water in a confined area and short out the line, rather than it having to be just in the junction box.

This happened to my family when I was about 18 years old (15 years ago) and it was a major pain in the *ss because I had the house full of then "illegal" phones. You need to (a) unplug all the phones and other telephony equipment in the house, (b) find the demarcation point where the line enters and (c) test the line there. If it still acts up, call the telco. What's going on is this... Theres a block where the phone line enters which has two carbon inserts connected to ground. These protectors are supposed to short to ground when lightning or other transients strike. If one blows, you've got a grounding problem. This causes the hum. The carbon block will be found in the basement, garage or on the wall outside the house. It will have two screw or bolt down terminals, and two other screw covers containing the carbons. The outside wire will be connected to the two bolt-down terminals. The inside wire will also be connected to those terminals. There will also be a ground which will be grounded (or "earthed" as our friends in the UK say.) If your house is new, there will also be a modular "demarcation point" which defines where telco responsibility ends and house wiring begins. If so, unplug the demarcation jumper and plug a phone into "their" side. If it hums, call them. If it don't you've got another problem, probably a grounding problem inside the house. Good luck, and let me know if I was right. -edg -- {decwrl|sun|oliveb}!CSO.3com.com!Edward_Greenberg Ed Greenberg -or- 3Com Corporation {sun|hplabs}!bridge2!edg Mountain View, CA 415-694-2952 ------------------------------ Subject: Re: Moderator Replies: MCI vrs.

One comment relative to the new plans, however: These are sounding one whole heckuvalot like the variable rate structures PUCs (thersthatwordagain) used to love so eliminate so much. How about this as an idea: Have the common carriers be _required_ to print on the bill to the customer what any available alternate carier would have charged (overall, mind you!) for the same calls, and _require_ them to print a detailed comparative analysis on demand for a customer against other carriers. To be fair this comparison should be forced on a "best service price" basis; i.e., no fair comparing the best AT&T rate with the worst Sprint rate. A more palatable form of this would be to require common carriers to print a cost analysis to a consumer against actual usage versus known rate structures with an eye toward _minimizing_the_bill_, based on past usage, or to allow a user to ask for an estimate given a prospective usage pattern. If you realy want to spook the carriers, the FCC could require a carrier to give the customer a bill based on the lowest possible bill among all plans over a running year interval of time ... yes, I'm dreaming .... roy a. crabtree uunet!ami!royc 201-566-8584 ------------------------------ From: roy crabtree Subject: Re: One Year Ago: The Great Fire Date: 9 May 89 18:52:56 GMT Organization: Access Methods, inc.

The new Sun SPARCstation-1 uses an ISDN chip for its audio interface (the AMD Am79C30). The chip is designed for use in an ISDN speakerphone; it talks the "S" interface (towards the phone network) on one end, has a micro-oriented 8-bit bus on another, two audio inputs (mike and handset), and two audio outputs (earpiece and speaker). It has full SDLC support for the 16kbps "D" channel, but the two 64kbps full-duplex "B" channels are simply accessed a byte at a time. It appears that Sun will not support plugging your SPARCstation into an ISDN phone line, because some standards committee somewhere decided that, when used for data, the "B" channels should carry SDLC-formatted data, and the SPARCstation (and the Am79C30) has no support for this. I find this the height of lunacy. The "B" channels are physically transmitted as 8,192 8-bit bytes per second. Each frame on the "S" interface has 4 bytes of "B" channel data. It knows where all the byte boundaries are, and it doesn't lose any of them in transit. If you think for a minute, this is obvious. Voice encoded into a 64kbps channel had BETTER retain its byte boundaries, since it consists of 8-bit samples which would be gibberish if resampled on random bit boundaries. So data encoded into the same 64kbps channel would also retain its byte boundaries. SDLC framing was designed for bit-oriented channels that need a certain number of clock transitions to keep their bit timing accurate. ISDN frames already provide byte orientation and enough clock transitions, completely outside the 64kbps of data. Any bit pattern, including infinite zeros and infinite ones, can be sent down the 64kbps channels without harm. There is no need for bit-stuffing here. If framing is desired (in some cases it may be), this should be up to the communicating parties to pick a framing. The "Asynchronous SDLC framing" standard, designed for another byte-oriented communications environment (sorry, don't have its X.number) would be a possible choice. A trivial software driver for this chip would let users transmit full duplex TCP/IP data back and forth between two SPARCstations at 64kbps, anywhere that end-to-end ISDN service is offered. I'm sure that someone will code one up and probably give it away like SLIP, but if the standard had been reasonable, this capability would have been built-in by Sun.

Menlo Park, CA Recently, I was asked to participate in a marketing focus group regarding business traveler's telephone usage. It turned out that the company sponsoring the research was AT&T. The nine people in our group (who were each paid $50) came from various backgrounds; the moderator was an employee of an independent market research firm. Most of the two hour session was spent identifying the telephoning patterns of the various participants. A special focus was made on alternative operator services and the problems experienced. One thing that AT&T is investigating is a special recording to be played just before entering your calling card number; the recording would identify the service as AT&T. It was implied that there would be some sort of an advertising campaign that if you didn't get the recording, you could then dial 10-ATT for an AT&T line. [Surprisingly, most of the participants did not know of 10-ATT]. The main complaint that most people had with the recording was not the idea, but the execution. The recording was about twice as loud as the touch tone sounds and had some (in the opinion of 100% of our group) terrible electronic music with a loud voice saying something like "Thank you for using AT&T". The current scheme is that you get a recording stating simply "thank you for using AT&T" after you enter the calling card number. AT&T wanted to know our reactions to having it before entering the number. About 75% of the group said that they would hang up and redial using 10-ATT if they got the message before entering their calling card number. No one said that they would redial after entering the entire long string of digits (as in the present type of recording). At one point in the discussion, they wanted to know our reactions to a sign, which all telephone companies would be forced to post on pay phones, that would specify that you could reach AT&T using 10-ATT! No one thought that was a good idea as it seemed that AT&T had gone a bit too far. They even had some proposed signs which businesses would post to indicate that all telephones inside were official AT&T telephones. (Like we accept Visa, Master Charge, and AT&T!). All in all, an interesting session. It will be interesting to see if any of the things presented for our opinions will ever see the light of day. -- Michael S.

They were remarking that the producers of that show would have to find a new title for it. If I understood the piece correctly, rather than the system used in places like New York where the more "central" area gets to retain the old, easily dialed and remembered, code, in London the 01 will be abolished altogether; part of the area will become 071 and the rest 081.

As far as I know it is EXPECTED (not required) that most ISDN data will be HDLC-framed. (e.g. X.25, proposed new packet-mode services) However, V.110 rate-adapted data is not HDLC-framed, and clear-channel data is not necessarily framed, either. Is there a standard restricting the format of clear-channel data to HDLC-framing? Who is responsible for that? What are they going to do about V.110? Names and document numbers would be appreciated - this is news to me and could be a Very Bad Thing. With luck it's just a misinterpretation on someone's part. I find it interesting that there is no HDLC controller on the B channels. How does the SPARCstation perform when it is being interrupted every 125uS?

[and goes on with another list of towns that may or may not be toll calls.] I cannot imagine what possible reason there could be for going into this level of detail on the net, but what do I know? :-) The basic point is that New England Telco charges different amounts for "Metropolitan" service depending on where you live. Roughly, in the richer suburbs they charge more and in the poorer suburbs they charge less. (Richer and poorer back when the tariff was created, long ago, not necessarily true today.) To justify the price differences they include slightly larger calling areas in the higher-priced suburbs. The upshot is that you can't tell what is a toll call by whether you have to dial a leading one or not. You can't tell without knowing your class of service AND where you live AND where you're calling AND the time of day AND the day of week. I had to code all this into a ham radio repeater's microprocessor. Anyone who cares about the specific towns can just look in the phone book and/or call the business office.

He then notes that area 708 has been assigned to Chicago, however this is not correct. Chicago will remain in area 312. 708 has been assigned to all parts of northern Illinois which were formerly in 312 and not in 815. He also notes that only two area codes remain unassigned before the supply of 'traditional' area code numbers is exhausted, and area codes begin to take a different format. My question is this: with the numerous three digit codes which are currently not in use which at least resemble, or 'look like' what area codes have always looked like, why are not those numbers being used first, before completely departing from tradition? For example, numbers like 310, 311, 511, 300, 400, 500, 600. While they do not conform exactly (never before two zeros in a row on a regular area code; never two ones in a row; when one is the second digit then the third digit is always two or more, etc...) but they still look enough like area codes that they would be more palatable to people than what I have heard is going to happen, using numbers like '689' or '327' which don't even closely resemble areas. Some time back when I said that the numbers 410,510,610,710,810,910 were unavailable as area codes since they were used by Western Union, I got almost hissed off the stage. If they are *not* out of circulation, then howcome they wouldn't be more suitable as area codes than what I'm told Bellcore is going to pass off on everyone?

Yes, I agree, your assertion above fails the sanity test. ISDN does NOT require any particular formatting of data on the B channel. ISDN's circuit-switched 64 kbps (unrestricted) bearer service places absolutely no constraints on what you do with your 64 kbps of isochronous bandwidth. You wanna run SDLC, run SDLC. You wanna run DDCMP, run DDCMP. You wanna run bisync, run bisync. Or fax, or low-bit-rate video, or 7 kbps ADPCM audio or whatever. The network's not allowed to touch your bits. In some US implementations, you may be limited to the 64 kbps Restricted bearer service. This is merely an artifact of the use of T1 carrier, which doesn't allow the all-zero octet to be transmitted, so that applies to 64R calls. Inverted HDLC of course runs fine in that mode. However, B8ZS and ZBTSI are two techniques for removing the restriction from T1; the telcos are installing them so 64R may be rare or nonexistent in practice. If the Sparcstation can't be used over ISDN, it's not the fault of the standards. fred (voting member, ANSI T1S1: ISDN Architecture, Services and Protocols) ------------------------------ From: Roy Smith Subject: Paying for directory assistance calls. Date: 11 May 89 16:50:24 GMT Organization: Public Health Research Institute, NYC, NY A few weeks ago I had to call a company in the Virgin Islands. I wasn't sure if they were on St. Thomas (part of the USVI) or on Tortola (part of the British Virgin Islands, the BVI). It turns out you can call either by dialing a "normal" long distance call -- area code 809 followed by 7 digits, even though the BVI only has 5-digit phone numbers. Anyway, I called directory assistance by dialing 1-809-555-1212 and got an operator who asked "which island please" and patched me through to Tortola directory assistance over what sounded like a radio-telephone link (the USVI and the BVI each consist of 3 large islands plus a number of smaller ones). I suspect the initial operator I spoke to was on the mainland because when I said I wanted Roadtown, he asked again which island I wanted. Roadtown is the capital of the BVI and by far the largest city (if you can call it that; I don't think it has 2500 people) in the BVI -- any local of either the US or BVI would know that without a second thought. Anyway, I got my phone bill the other day. The DA call was $0.60, under the heading "Directory Assistance, Canada and Area Code 809". I've never been charged for DA before, even DA calls to Canada, so this was curious (but hardly worth making a fuss over). The interesting thing was that I made a total of 4 toll calls to the VI that day -- 2 1-minute calls for $0.13 and 2 2-minute calls for $0.26. That one quick DA call, which is "supposed to be free", cost me almost as much as the 4 toll calls combined, totalling 8 minutes!

Does anyone have further information? Why would 903 be revived before 908, 909, and 917 have been used even once? Why, when it comes time for 903 to be reused, would be it placed in a state (albeit at the far corner of that state) along the Mexican border, comparatively close to where the original 903 [now 706] was, when there are other area code splits in the works much farther from the old 903?

PT] 706 and 905 are used for parts of Mexico, right? Also, I believe 708 will pick up Chicago SUBURBS; the city exchange stays in 312. Will that new area 903 in NE Texas get any N0X/N1X prefixes? It's just my guess that it will not; the only N0X/N1X I know of in the present 214 area is in Dallas and nearby. As is the case in the Washington area suburbs, when you assign prefixes in Dallas and suburbs you have to consider your area code and a big chunk of a neighboring area code as well. With 708,903,908 being assigned in the next 2 or 3 years, and 909,917 unused (I have no comment here regarding N00, N10, N11), you wonder about the poor souls who will end up in the first NNX area code. There have been some problems noted reaching new prefixes (not limited to N0X/N1X) and new area codes. It's also been noted that 415 area (includes San Francisco) may split later (no code announced yet, right?); that area recently prepared for N0X/N1X prefixes. Up to this point, all of the N0X/N1X I know of in Maryland and in 703 (Va.) has been in the DC calling area, which ran short of NNX. Last night, I got my hands on a Baltimore call guide of Nov. 1988, and discovered 2 such pre- fixes outside the DC calling area: 915 Baltimore city (915 in DC was for some recorded messages; don't know about this one) 303 Columbia (local call for Silver Spring, which is also local to DC & suburbs; also a local call for Baltimore city) Perhaps you'd want to set up an archive file explaining such codes (why they are not used as regular area codes--yes, I know about 411,611,911,800,700,900). Hasn't that question been asked before? [Moderator's Note: Why 411-611-911 are not used as area codes is pretty obvious, since they equal Information, Repair Bureau, and Emergency in that order. But why can't numbers like 210-310-311-511 be used? Or numbers like 410-510-710? They at least resemble area codes and would not be so confusing to a phone user.

I have repeatedly tried this, and failed. The local BOC payphones usually DO allow it, but certainly not always. 2) Denver Airport: The BOC there (US WEST) phones default to Sprint, and the phones are very clearly marked as such. 10288 works fine there. Houston Airport: The phones are NOT marked, I think you get BUM-Stench Communications as a carrier. About 40% of the big advertisements in the corridors of the airport are flashy placards telling you, in 2" letters, how to access AT&T by the 10288 method. Obviously 10288 is ok here as well. 3) What has failed in only the rarest of COCOT situations is to use Sprint's LD service via the 800-877-8000 access. A few of them shut off the keypad's tone generator after the connection is made, but at least an operator answers, and you can still complete your call, with a $1 surcharge (still a lot better than AOS rates!) I find that the ATT charge-card phones (the silly ones with the CRT and card-reader) usually shut off the keypad, but otherwise the BOS phones are OK. BUMSTENCH phones are usually OK as well.

Our experience is that each of these (SBS Skyline, MCI, and AT&T) shows significant variation between different calls to the same place, using the same carrier. The variation in data transmission quality varies even more among calls placed over the same carrier to different destinations. The variation between these carriers was no more than the variation between different calls using the same carrier. We also find plenty of noisey intra-lata calls. If the local carrier cannot deliver a clean dial-up circuit across town, how can they be expected to provide a uniformly clean interface to any of the inter-lata carriers?

How are you proposing sending more digits/extensions other then the phone numbers administered by your local operating company? If you are only getting basic 911 service without ANI/routing capabilities sending more information from your PBX own't help the PSAP. On the other hand, if you are going to connect into an Enhanced 911 PSAP I have a few questions. An Enhanced 911 PSAP has an address database that must be maintained by someone, how or will the university keep the database informed of extension moves. Will the PSAP even want to know about these numbers? If you are going into an E911 PSAP could it even handle a DN followed by an extension? I didn't think E911 was currently capabile of this. If the E911 is going to be used for routing the calls and your university is split over multiple juristictions I believe most of the call routing will be based on the PBX trunks billing number now originating extensions, since that is a reason for most PBXs to provide extensions not necessary known to the local switching offices. ------------------------------ From: Steve Dyer Subject: regular noise/interference over long distance credit card calls Date: 12 May 89 14:45:40 GMT Reply-To: Steve Dyer Organization: S.P.

If the batteries are hopelessly shot, or not even there, or good and you have a long (>one hour) power failure, then when the power comes back on, the machine rewinds the incoming message tape. Yes, you noticed that. It happily writes all over the messages that came in before the power failure. 3. If the batteries are marginal, and there's a power glitch, the machine puts both tapes into FF and runs them until they are banging at the end of the reels. It then starts to smell like it's going to produce copious amounts of smoke and flame. 1 and 2 were confirmed by Phonemate's 800 number as "That's the way it works." 3 was observed once, first-hand, and is the reason that I don't keep any batteries in it. -Sandy ------------------------------ From: Rick Watson Subject: Re: PhoneMate Answering Machine Problem Date: 13 May 89 16:37:14 GMT Organization: The University of Texas at Austin, Austin, Texas > I have a PhoneMate 9750, their top-of-the-line two-line answering machine > with a built-in telephone.

While the 9750 has some nice features, it has a very low-security touch-tone remote operation code. Worse, I can always tell when someone else's 9750 answers because of a distinctive answering characteristic. Also, the touch-tone decoder on my 9750 has drifted and had to be re-adjusted.

Snyder" Subject: Re: PhoneMate Answering Machine Problem Date: 15 May 89 02:46:33 GMT Organization: MIT Media Lab, Cambridge, MA I also own a PhoneMate 9750 answering machine, which I have used for the last three years. Its behavior over that time has been peculiar in a number of ways. For the first six to twelve months, the VOX circuit seemed deaf and impatient, but that problem "healed" over time. While it was a problem, I just instructed the people who usually called me to speak loudly and quickly, which got around the problem. The other problem I have had is DTMF deafness, but it seems to vary over time. Sometimes it is quite sensitive, but other times (often only a few seconds later) it's completely deaf. I used to think it was the telco trunks, but after MIT's cutover to our new 5ESS (with completely new cable plant) last fall, I ruled that out. I opened up the PhoneMate and found four trimpots on the board. I tried adjusting them, but it did not seem to have any effect. I never use the built-in handset. In fact, I have kept always kept the PhoneMate in a clear plastic bag to keep it looking new and operate it through the bag. (I use only a 1970's vintage WECO 2500 set or my 1960's vintage WECO 3B speakerphone when I want to talk on the phone.) I've always wondered why PhoneMate used those expensive 6V photoflash batteries for backup. The batteries cost ~$12, and I only paid $60 for the machine. I overcame the problem by wiring up an external 8 AA-cell alkaline pack. Overall, I have been very pleased with the PhoneMate. Sure a few analog levels aren't quite right, but the uP software is good, as are the front panel controls. The thing I like most about the PhoneMate is that it either does exactly what you want or (if it's deaf) does nothing (and retains all messages). I've never lost a message with it. I also believe Code-A-Phone makes good machines, but not as good as they used to (e.g. Ford Industries Code-A-Phone Model 200: the "Chrysler" of answering machines). -Ross ------------------------------ From: James Turner Subject: Re: HELP!!

For some reason, people seem to delight in searching for these numbers, when there is a much simpler solution to their problem. When I was working in NY, I had a similar problem (multiple lines with unknown numbers). I simply hooked up a handset to the line and dialed the closely kept secret telephone company number, "0". When the operator came on the line, I explained that I needed to know the number of the phone I was calling from. She read me the number off the TSPS console. End of story. [Moderator's Note: That may be the end of your story, but many telecom participants, myself included, have found that normally the operator will NOT say what number the call is coming from. The rule is they aren't supposed to do it, for various security reasons. PT] ------------------------------ From: jad@dayton.UUCP (J. Deters) Subject: Re: HELP!!

I feel I can address this terrible misconception that has been being passed around the net. ISDN does not mandate HDLC or any other framing for B-channel data. While some standards exist for particular data transfer arrangements, there is intentionally left of the user to determine what data will be sent and in what form. When a request for a 64 kbps clear channel is granted, the ISDN guarentees that 8 kilohertz integrity exists. This means that bit in is bit out. Any bit oriented protocol can be used. It is up to the two end users to determine a way to agree to what the data transfer protocol is, and haow it will be used. For CCITT standard protocols (e.g., X.25), there are ways to pass information about the throughput, rate adaption protocol, etc. I don't know the problem with the Sun workstation that started this discussion, but I suspect it is based on misinformation somewhere along the line. If there are specific questions or comments on what I have said, I will be very willing to supply chapter and verse from CCITT Recommendation X.31, or Q.931 (which I am the editor of the data parts of), or other CCITT Recommendations on the topic.

I know that an RJ-21X is one > of those rectangular connectors that can accomodate up to 25 (?) dialtones. > What about the RJ-31X? Thanks. OK, let's start with the RJ-21X, because it is not "one of those rectangular connectors". The rectangular connectors are known as "Amphenol" connectors, although they may also be made by Cinch, Amp or other people I have not heard of. They are known in FCC Rules and Regulations Part 68 as "50 Position Miniture Ribbon Plug". Now you know why they are called "Amphenols" An RJ21X is a 66 block that is used as the "Demarcation Point". This is the point at which the telco hands the lines over to the customer. This is a "split" block using bridging clips so each line can be disconnected at this point for trouble shooting and finger pointing. Most RJ21X blocks have an Amphenol jack on the side so you can save time etc by plugging an Amphenol plug in that leads directly to your PBX or Key system etc. This saves having to run individual pairs for each of the possible 25 trunks. Most RJ21Xs have less than ten trunks on them so usually the trunks are punched down with regular wire. The RJ21X description in Part 68 states a few things which are not common practice. It does not mention the 66 block and states that the telco will consecutively wire the lines - not true with Pacific Bell, they put them on any pair you state, i.e. PBX lines 1 - 15, FAX line 25, Modem line 24. When Part 68 was written, the use of "RJ21X" as a demarcation device was not common, hence their description of typical usuage "Traffic Data recording equipment". An RJ31X is an 8 position jack with a few extras. They are used mostly by alarm companies. When used by alarm companies, they are wired so that a line runs through them in series. What this means is that the pins have special shorting bars across them. For example: Tip comes in on Pin 5 and via the shorting jack leaves on Pin 8. Ring comes in on Pin 4 and leaves on Pin 1. Now when the alarm company comes along, they plug their alarm dialer (The one that calls the alarm center or the fuzz) into the RJ31X. The shorting bars are now lifted and Tip and Ring runs through the dialer. When the alarm goes off, the dialer will disconnect the customer side of Tip and Ring and dial out on the Telco side (Pins 4 & 5). Note: Many alarms sense voltage on the line and if you randomly unplug the RJ31X, the alarm will go off and make more noise than a heavy metal concert. Usually, you put the alarm on the least used pair, often the last or your FAX line. Note that the RJ31X is an 8 position modular device, sometimes called a "business jack". Regular phone jacks are 6 position modular devices. The same jack will change its number depending its usage. When the same jack is wired the same way, but used for an automatic dialer (Not an alarm dialer) it becomes and RJ32X. When used with a "Data Set" (Modem) it becomes an RJ36X. If it is for a modem with "programming resistors", but no shorting bars, it becomes an RJ41S If you are feeling confused by now, don't worry. If you have to install an RJ31X, they usually have instructions and drawings in the box. If all else fails, you may be lucky to get an alarm installer who understands these things.

Sounds suspiciously like you have a blown ground protector. This is a fuse like device in the junction box, where the telco cable comes into the building. It's purpose is to prevent excessive potential (like a lightening strike) from entering the equipment. Another possibility is a high ground on the cable, this could be either inside or outside wiring. Telco can rapidly test for a ground and tell you if the problem is theirs or yours. Odds are, since you mentioned the storm, that the protection fuse has done its job and needs to be replaced by the telco.

I've been told that it produces automatic number identification in a few central offices, but I haven't heard which (anyone else in NJ know of any?). I think most of the N10 codes are/were assigned to TWX, weren't they? My copy of "Notes on the Intra-Lata Networks" (1984, Bellcore) lists codes 211, 311, 511, and 711 as RESERVED. This publication extimates that by 1995, we will need Interchangeable NPA codes. This refers to area codes of the NNX format, just like CO codes. Before that time, ALL local switching systems must have been modified to require 1+ dialing. If anything, recent events indicate that the 1995 estimate may be off. I wonder how much difficulty would be caused if the USA and Canada were to be assigned different country codes?

PT] ------------------------------ From: paul@nsacray.uucp Date: Sat, 13 May 89 19:33:57 GMT Subject: Miscellaneous Comments I believe an RJ31 is an oversized modular connector with eight wires. They are used a lot in multiline dialers, etc. If there is interest, I can post what each wire is used for (I think it's pretty standard - My Mitel Smart-1 Call Controller uses them). As for using an operator when a COCOT keypad disconnects, generally if you explain this to the operator, the call will go through at regular rates (no surcharge). It was mentioned a few weeks ago that AOSs seem to have incomplete Calling Card databases. This is true, as there is no central point for calling card info. Certain independants have refused to give out this info. Also, the private verification databases don't have corporate cards (yet). So anyway, you can use just about any number as a calling card (just make sure it meets modulo 13 checks). There is an old story about the president of Microdevices (an AOS) using the president of ITI's (another AOS) home number with a made up PIN whenever he was in an ITI serviced hotel. There is a catch here, some sleazy COCOTs (and some AOSs - ITI started this), use the AT&T calling card database. What they do is after receiving the calling card number, they (the payphones or AOS switches) dial 10288 + 0 + NPA + NXXXXXX then dial the credit card number. By `listening' for the 'thankyou for using AT&T' (really energy detect with timing) they can determine if it is a valid card. As for using two payphones to make third party calls...... AOSs will be hit the worst (because of their backwards technology). Students often do this from their dorm rooms. It is true that in certain areas payphones were assigned a special office code, or last four digits (often beginning with a nine). This generally is not true for COCOTs. This makes screening difficult. A natural addition to AOS software would be to do lookups on third party billing numbers against other payphones on the switch, since COCOT payphones usually come in banks. AT&T and the other majors will eliminate this problem with LIDB lookup via CCS7. -------- Paul Guthrie chinet!nsacray!paul Zippy says: HOORAY, Ronald!!

I just completed a 14-day stretch of audio engineering for The Jason Project, which I feel has been a landmark in telecommunications. It may have been in your city. Woods Hole Oceanographic, Electronic Data Systems (EDS), and Turner Broadcasting System worked together to bring thousands of children in 13 U.S. cities live interactive television from the Mediterranean. A robot named "Jason" which was developed with the U.S. Navy, went down to the ocean floor with high-res color TV cameras to bring beautiful video of, and retreive, Roman artifacts 1800 years old. The children, at museums, were able to talk directly with the exploration team, headed by Dr. Robert Ballard (credited with the "Titanic" find) by means of telephone interfaces here at TBS in Atlanta, which we mixed into the show, as well as into a phone line (a dial-up) to Holmdel, NJ. This line was then uplinked to Pan-Am Sat 1, and received by a 2 meter gyro-stabilized dish on board the Star Hercules. This same dish provided uplinking for video (encrypted with 2 channels of DIGITAL audio as well as a data stream allowing scripts to be fed back to Atlanta from a laptop PC on the ship). EDS also provided several direct-dial phone "lines" to the ship (which appeared as New Jersey telephone numbers on board the ship) over which we sent production coordination information, and received backup audio. We produced 84 television shows, placed approximately 250 calls to museums using primarily US Sprint (though we occasionally used AT&T when Sprint circuits arrived at "low" audio level). We DID find that, at least here in Atlanta, AT&T lines come out LOUDER, even with the sometimes higher noise floor, than do the Sprint mostly fiber optics. If anyone saw the show at any museum sites, I'd love to get feedback. -- Turner John Wheeler E N T E R T A I N M E N T ...!gatech!nanovx!techwood!johnw Networks Techwood Library * home of Superstation TBS * TNT * TBS Sports ------------------------------ From: "Ross D.

Geographically, I have been told it will go from Tyler east to the state line, and south from the state line to a someplace south of Palestine. As to what area codes are suitable in this area, well Fort Worth ( the unheard of half of Dallas/Ft. Worth ) is in the 817 area code, as well as nearly everything else west of Dallas. Even Waco on the south, and Denton on the north are in area code 817. That probably makes 917 unsuitable.. About 909, I don't know. Maybe Southwestern Bell made it to Bellcore before Pacific Bell. :-) -- Eric Schnoebelen, JBA Incorporated, Lewisville, Tx. egs@u-word.dallas.tx.us ...!killer!u-word!egs "...we have normality"..."Anything you still can't cope with is therefore your own problem..." -- Trisha McMillian, HHGG ------------------------------ From: Gerry Wheeler Date: 15 May 89 17:38:47 GMT Subject: Re: Area Codes - a few comments Organization: Mortice Kern Systems, Waterloo, Ont.

PT] There have been several messages of late commenting on suitable area codes, and I think this is the second time the moderator has made this point. As a non-insider, I would estimate that 99% of telephone users have no preconceived notion of what an area code looks like. It is simply three digits. Heck, I didn't know there were restrictions on area code numbering until I started reading this group, and I used to work for the phone company! There were also previous messages about whether this area code or that should be assigned right next to some other area code that was similar. I don't think there is any difficulty with that from a user point of view. (I can't say whether there are technical reasons for avoiding it.) After all, one seldom knows what area codes adjoin the desired one, and if you misdial you get some wrong party -- it hardly matters if they are 100 or 10000 miles away from the party you intended to dial. Is there some inside reason why these points are important? I don't see them affecting how the ordinary user sees the phone system. -- Gerry Wheeler Phone: (519)884-2251 Mortice Kern Systems Inc.

I'd suggest not putting it on a FAX or modem line. For quite a few months here we were having problems with both our FAX and modem connections being terminated randomly. For modem use, it was obvious that no connection ever lasted for more than an hour. It turned out that all the lines involved were passed through alarm systems (at least one for intrusion and one for fire) and the systems were "testing the lines" hourly! We decided to get dedicated lines for them, since, in addition to this annoyance, we didn't want an incoming call to potentially hold up the alarm.

Normally I only bother comp.dcom.telecom readers with USENET administrivia, but I would guess that the TELECOM Digest has been really impacted (is that a verb?) by the problems the last few weeks, and the mailing list readers must be wondering too. So, I pass along the gruesome details to them too. The short story is that there were some big problems here at vector.dallas.tx.us. These problems have been resolved, and based on the last week of traffic the link is now reliable. However, one of the fixes requires manual intervention in the gateway processing, and therefore, will add about a day to the turnaround time. The long story is that there were two problems here. The first was that until two weeks ago, vector.dallas.tx.us was running a version of XENIX with a crufty version of uucp. This version had a tendency to throw away messages if the line disconnected, which happens frequently here. The solution has been to: (1) upgrade to a newer version of XENIX with HDB uucp which doesn't throw things away, and (2) install a Trailblazer modem which does a much better job with bad lines. The second problem was that the program which automatically drops the mailed digest into the gatewaying program started to instead drop them into a black hole. The resolution here was to drop them into my mailbox instead, and manually process them from there. Unfortunately, this means that manual intervention is required, and adds some delay to the processing. But I keep traditional hacker's hours, so the delay is usually well under a day. (This should be resolved in 2-3 weeks, when I upgrade to a new mailer here.) Anyway, things appear to be running once again. I appologize for the problems in the interim, and I appreciate yours and Patrick's patience. So, what do you say we all go over to comp.lang.c, kick some butt, and tell them what "#" is really called. :-) (If you missed it, the pound, number, square, octothorpe, tic-tac-toe argument has been going on there for the past two weeks.) -- Chip Rosenthal / chip@vector.Dallas.TX.US / Dallas Semiconductor / 214-450-5337 ------------------------------ Date: Tue, 16 May 89 11:02:04 EDT From: Carl Moore (VLD/VMB) Subject: TELECOM address in US mail That announcement from you didn't even mention the city.

The format is specified by a mystery chip (voice processor) that I believe to be manufactured by Toshiba. Can anyone help? More information follows: The DVC is a playback/record system that records audio on hard disk as a bit stream, using one of the many variants of the Adaptive Delta Modulation (ADM) technique. The ADM technique produces very compact audio files but is not very convenient for audio analysis. For analysis, Pulse Code Modulated (PCM) data is much more convenient. In fact, the DVC takes audio data as PCM but converts it on board to ADM. There are no part numbers on the chip or in the documentation. What I need is an algorithm (especially in the form of a C program) for converting between the ADM and PCM just as the Voice Processor chip does.

For those of you interested in the sci.commtech call for discussion: an update. All the feedback has been positive, and much of it has been enthusiastic. The idea is to bring together various professional backgrounds to a common interest: new communication technologies and their impacts on society, media industries, organizations, and individuals. The latest developments in technology would also be posted and discussed. The difference between sci.commtech and, for example, rec.video or rec.audio, is that sci.commtech will *not* be the place to post inquiries as to what equipment one might wish to buy. There has been some discussion about the name, with sci.comm.tech being a common suggestion; Usenet authorities tell me sci.commtech is better as the former implies a second heirarchy. Another good suggestion is to call the group sci.infotech. Please post your reactions to news.groups, and watch for a call for a vote in the next couple of weeks.

PT] Historically, the N10 codes were used by TWX (otherwise Telex II); whether this is still true, I don't know. AT&T set up TWX to compete with Telex, and used a hitherto-empty part of its name space to avoid interference. Later, AT&T had to sell off TWX, but the N10 codes are still treated as sacred. The last time I checked into the matter, which was maybe 15 years ago, my local telco (New Jersey Bell) treated some N10 codes as "invalid exchange" and others as "invalid area code", kind of randomly. [Moderator's Note: But some readers have maintained, very vigorously, that since Western Union central offices are in no way connected with or wired through Bell central offices, their use of those numbers have no longer any bearing on area codes.

Date: 15 May 89 22:39:38 GMT Someday, if we're all very lucky and still alive, the entire world will use ISDN and it won't matter whether framing of packets in an ISDN channel uses byte oriented or bit oriented techniques. In the meantime, when there's a need for an ISDN device to talk to a non-ISDN device they had better agree on a protocol and SDLC framing fits the bill just fine. The V.120 standard seems to be the emerging winner for communication between ISDN and non-ISDN devices and it does indeed use SDLC framing. In my opinion, it is neither the power nor the purpose of ISDN to provide 64Kb channels between computers; rather, it is to make available all the telecom/datacom things that the phone system provides today from a single interface, and to provide continued interoperation with all the existing devices hung off the phone system.

Even at MCI, the circut quality could even depend on the time of day you call. Scenaro: You call from San Francisco to New York. If you called at 9pm, your call would travel over our backbone fiber that runs between San Francisco and Washington DC, then via digital radio to New York (over-simplification here), but it is possible that you try at 9AM instead, and all trunks are busy on that fiber route, then we have to find an alternate route for you call to terminate in New York. So, lets see, we send you to Los Angeles first, then Phoenix, Arizona, then Dallas, Texas, then St. Louis, Missouri, then......you get the picture.

When I call Cupertino at 2400 baud, I always get a bunch of curly characters at the beginning of the transmission, usually going away after repeated 's (or, during retraining/equalization). This usually points towards frame errors/slips on a T-1 carrier, a common problem on the DMS-100, but I have also gotten this while calling through MCI which we have direct circuts to that C.O., but not from work, where we route through San Francisco instead (I think it's San Francisco 10 or 12 were on). I searched my own calls from work, and they terminate directly into SNJS/12, but I have no way of searching my intralata calls to see if I hit the tandem on their end (Santa Clara) or my end (Oakland), and see if one of the tandems is screwing this up. Of course, trying to explain all this to repair (611), and they usually say "huh?". Let us know if you do proceed with the modem experiments, and the results and problems you encounter.

As the person responsible for our company's phone system, I was recently served with a "Violation Notice" and given two weeks to wire our lines to the 66 block VIA the amphenol connector. The straight "them on one side --- us on the other" with bridging clips in between is NOT ALLOWED here. I was told that if I did not correct the problem, service would be terminated. If you receive service by means of an RJ21X, the phone company wants to have the ability to disconnect all of your lines with one simple yank of the amphenol plug, wonderful. More recently I ordered yet another line (for a credit card verification frob), and the installer wanted to put up a standard network interface box (like the ones they use outside new residences) rather than put the line next to the existing ones. (The RX21X is inside a phone closet in the building). The reason is apparently that you are not supposed to have lines with different "class of service" on the same 66 block. When I explained that we already had a mixture of stuff on the 66 block; 12 CO lines in hunt, 2 fax lines, and 2 modem lines, he agreed to punch the new line down with the rest, mumbling about how the PUC makes them do all these silly things.

Steve, Most phone calls are transmitted as a stream of digital data. (Odd, ain't it; the modem converts digital to analog so the central office can convert it back to digital for transmission...) This digital data stream passes from one network switch to another. The network switches probably aren't synchronized to the same clock. One switch is running slightly faster than the other; thus the digital data stream is constantly and steadily "slipping" as it passes from one to the other. The scrambled bit pattern often contains characters ~ or } or DEL (they're rich in 1-bits). A quick workaround? Route the call along a different path. Using a different LD carrier is very likely to accomplish this. -- Jeff Stearns John Fluke Mfg. Co, Inc.

My setup is as follows: Two phone lines coming into my room. Line 1 is normally used for voice calls and line 2 is used for my modem calls. All my jacks are wired back to an entrance bridge I have near the telco network interfaces with 4-wire station cable. I use six inch modular to spade lug line cords to connect from the bridge to the telco network interfaces. Line 1 is supplied via the RED/GREEN pair while line 2 is supplied via the BLACK/YELLOW pair of the jacks. My problem is that when I am logged onto any system via my dialup modem and my answering machine answers my phone, my modem drops carrier and my session drops. I can also hear my modem carrier whenever I use line 1 and the modem is in use. It seems to me that the answering is causing some sort of glitch on line 1 that is being picked up on line 2 whenever it answers an incoming call. Question 1: What can I do to prevent this from happening, short of wiring a new jack which has two cables running to it, one supplying line 1 and the other supplying line 2. Question 2: If I had wired my jacks using twisted pair cable instead of the 4 wire station cable, would I still be seeing this problem? Would it make a difference if the cable were shielded? The reason for question 2 is if I ever move into a different place, should I wired my jacks using 4 wire station cable or with twisted pair cable? I figure I might as well get things right the next time around, since I will in all likelyhood have at least two phone lines coming into my next house/apartment.

Raymond" Subject: Honey-Danber UUCP and the Telebit Trailblazer -- a how-to Date: 14 May 89 18:34:54 GMT Followup-To: comp.dcom.modems (per request of TELECOM Moderator) This is revision 2 of the everything-you-always-wanted-to-know-about-the Trailblazer-but-were-afraid-to-ask posting. It supersedes my posting of 16 Dec 88 23:29:53 GMT. I have bothered with this revision because Telebit's documentation, while relatively quite good for a product of this type, makes too many assumptions about what the user already knows and can do. Here's how to set up your system to use a Telebit Trailblazer modem for uucp, cu and kermit (almost all of this applies to the Telebit T1000 and T2000 modems as well). First, I describe how to set up dial-out use; then, how to enable dial-in. First, get one of your serial ports to talk to the 'Blazer via kermit or cu. To do this via kermit, you'll need to `set line' to the UNIX device associated with the serial port, `set speed' to 9600, and perhaps `set parity' to N. To use cu, you'll need a Devices file entry that looks like Direct tty000 - 9600 direct and you'll invoke cu as cu -l/dev/tty00 where tty00 should be replaced with the name of the serial port your modem is connected to. It's possible your cu may also need an `-s 9600' option; to see what it does as it tries to connect, use -d. Once connected, you want to enter the following commands: AT &F Q6 S51=4 S52=2 S53=3 S54=3 S55=3 S58=2 S66=1 S92=1 S95=2 &W &N Note: these settings work on a System V 3.0 running on generic 80386 AT-bus hardware with 8250-based serial ports. See the notes below for what to do about strange machines like the T5100 or AT&T 7300. If you enter incorrect settings, you can correct after hard-resetting the 'Blazer. Older versions have a microswitch on the back of the modem; on newer ones, you just turn off the power, hold down the T/D switch, and power on again. Keep T/D pressed until the 'MR' light comes on. If the 'Blazer hangs up when you type after the above command, you have incorrect settings; probably S53 and/or S58 are wrong. Hard-reset and see note 3 below. Explanation of the settings above follows: AT &F ; Reset to factory defaults AT Q6 ; Return result codes only on outgoing calls. AT S51=4 ; Use constant 9600bps speed to modem (but see Note 1) AT S52=2 ; Reset to configuration memory values on DTR drop. AT S53=3 ; DCD on carrier detect, DSR on when modem off-hook. AT S54=3 ; Pass BREAKs transparently. AT S55=3 ; Don't allow escape to command mode AT S58=2 ; Use hardware (RTS/CTS) flow control. AT S66=1 ; Lock CPU-to-'blazer speed at S51 value AT S92=1 ; Try PEP tones at end of autobauding sequence (see Note 2) AT S95=2 ; Enable MNP if other side wants it AT &W ; Put these parameters in the configuration memory AT &N ; Check the configuration values for correctness What you're doing is setting the modem up to use a fixed speed of 9600bps to talk to the CPU, but autobaud outgoing calls with PEP tones last (the settings of registers 51, 66, and 92 accomplish this). The Q6 command disables generation of some command responses in answer mode. The S52=2 tells the modem to reset to default values at the end of a call (this is necessary, because some of the dialer scripts will change settings). The S53=3 is important; without it, UNIX will think the modem line is active all the time and uucico/cu/kermit may not be able to get past a deathless getty hanging on the port (this happens on Microport 3.0e). However, on some other configurations you can and must set S53=0; the AT&T 7300 and T5100 need this, but the getty will be interruptible and everything should function normally. S54=3 prevents the BREAKS that you put in expect/send scripts in order to force the callee to autobaud from getting intercepted by the modem. S55=3 guarantees that your modem won't be dumped into command mode by an escape sequence showing up in binary data. S58=2 enables the cleanest kind of RS232C flow control between the modem and your serial card. If you are using 8251-based port hardware (in particular if you are using a Toshiba T5100 or other portable with CMOS-only innards) this may not work! See the discussion of flow control below, Note 3. The significance of the S92 register is covered in Note 1 below. Finally, S95=2 enables MNP protocol checks (some dialer scripts turn this off). These settings make you back-compatible with a Hayes, so that kermit's dial command will still work through a vanilla ACU/hayes device connected to the Trailblazer port. Other cases are handled by commands in the Dialers scripts. Do *not* set S67=1! This looks logical but doesn't work. Also, you don't need to change S110 or S111 to get compression and 'g' protocol spoofing; by default, callers can select it, and the Dialer scripts will do the right things for outgoing calls. Note 1: the promise and peril of 19200 If you're willing to give up using kermit(1) 4D (which only supports a 9600bps maximum) you can jack the CPU-to-modem speed up to 19200 (S51=5). In that case the `9600' speed fields in your Devices and Systems files should all change to `19200'. If you have kermit source it is not hard to hack it to support 19200 -- but your serial port drivers may not be able to handle this without clist overflow! Some UNIXes on AT-bus machines are rumored to have problems this way (Microport is one such). If you can use RTS/CTS handshaking (see note 3) the modem will, effectively, do buffering for you and the problem goes away. If you're using a smart multiport card like the ACE, also no problem. But if you're stuck with a 16Mhz or slower processor, a dumb serial card and no handshaking, you may lose characters at any speed above 2400(!) baud. Note 2: catering to old slow broken modems. You may well be able to run with S92=0, the default (PEP tones first). The S92=1 setting is conservative; it guarantees you compatibility with 2400bps modems that are either too dumb (so they mistake the PEP multi-carrier burst for a V.22 answer tone) or too smart (so they think it's a human voice and hang up). V.22 modems built to spec shouldn't do either. The cost of this conservatism is that 'Blazers running firmware release 2.2 or older, or with the S7 carrier wait time set to less than 60 seconds, may not be able to recognize yours; and you impose a longer handshake sequence (with increased chance of uucico timeout) on all Trailblazers. Note 3: handshaking considerations 8251-based ports have only one handshake line; the T5100 appears to use this for the DSR/DTR pair. Therefore RTS/CTS handshaking won't work. If setting S58=2 causes your 'Blazer to hang up, but you are not sure there's an 8251 in the woodwork, try S58=1 (half-duplex RTS/CTS). Human dial-ins may not like the effects of this setting, however. If neither of these work, you *may* (repeat *may*) have a problem. XON/XOFF handshaking can cause lossage as UUCP 'g' processing tries to interpret ^S/^Q. Therefore you are stuck with S58=0, no handshaking. This is certainly OK if the sites you talk to always use PEP or g-protocol spoofing, these modes disable flow control anyhow. It is alleged by the uunet people (who have one of the world's largest collections of 'Blazers, and thus ought to know) that connections through the 'Blazer at 1200/2400 cps work just fine with no handshaking. And I have been using a T5100 connected this way for a couple of weeks without obvious problems. So all of this may be a non-issue. Comments from RS-232 experts or anyone else with solid practical knowledge are invited. Further note: if your installation is outside the U.S.A. you may need to tweak the S90 and S91 registers, either to new default values or within the dialer scripts. See the Trailblazer documentation for details. Add the following lines to your Dialers file: ########## # Telebit Trailblazer Plus, T1000 or T2000 # # assumes Q6 X1 S51=4 S52=2 S53=3 S54=3 S55=3 S58=2 S66=1 S92=1 S95=2 in EEPROM # tb1200 =W-, "" \d\K\dATE0 OK ATS92=0S50=2S95=0DT\T CONNECT\s1200 tb2400 =W-, "" \d\K\dATE0 OK ATS92=0S50=3S95=0DT\T CONNECT\s2400 tb2400n =W-, "" \d\K\dATE0 OK ATS92=0S50=3DT\T CONNECT\s2400 tbPEP =W-, "" \d\K\dATE0 OK ATS92=0S95=0S50=255S7=60S111=30DT\T\r\n\d\d\d\d\d\d\d\d\c CONNECT\sFAST tbPEPc =W-, "" \d\K\dATE0 OK ATS92=0S95=0S50=255S7=60S110=1S111=30DT\T\r\n\d\d\d\d\d\d\d\d\c CONNECT\sFAST # The magic parts of these scripts are the delays after connection, which hold off handing control to uucico so it won't time out during the PEP negotiation. Now add the following lines to your Devices file: # --- Telebit Trailblazer/T1000/T2000 devices ------ # # Devices for access to a 'blazer on tty00 ACUTB tty00 - 9600 tbPEP ACUTBC tty00 - 9600 tbPEPc ACUTB2400 tty00 - 9600 tb2400 ACUTB2400N tty00 - 9600 tb2400n ACUTB1200 tty00 - 9600 tb1200 If you have more than one Trailblazer, just duplicate the list above once for each tty device connected to one. All your Systems file entries that are associated with any of the Trailblazer devices should have a speed field of 9600 (to match the speed in the Devices file). You set the actual speed of the connection by which ACU you pick -- note that the PEP entry corresponding to ACUTB autobauds, so you can usually just use that. The ACUTBC entry may be better for mail and news feeds, as it enables data compression for up to a 2:1 cut in transmission time. Compressed PEP with g-protocol spoofing running on reasonably clean phone lines can often give your UUCP a throughput of as much as 14K text characters per second! The low-speed entries avoid throwing PEP tones at modems that may be confused by them. ACUTB2400 should fall back to 1200bps if it needs to. ACUTB2400N may be useful for Telenet MNP access. The N- and C-suffix devices request compression and MNP modes from the remote respectively. The above is designed so your ACU entry can be untouched and still work for use with the kermit dial command (which doesn't know what to do with the tb* devices). If you don't care about kermit, you can call the tbPEP device ACU. Now for dial-in access. First, you need to create appropriate gettydefs and inittab entries. First, add the following to your /etc/gettydefs file: BLAZER# B9600 HUPCL OPOST ONLCR TAB3 BRKINT IGNPAR ISTRIP IXON IXANY ECHO ECHOE ECHOK ICANON ISIG CS8 CREAD # B9600 HUPCL OPOST ONLCR TAB3 BRKINT IGNPAR ISTRIP IXON IXANY ECHO ECHOE ECHOK ICANON ISIG CS8 CREAD #login: #BLAZER (whitespace added for clarity; this must be all one line). This instructs a getty running at BLAZER speed to look for logins at 9600bps only (you can use 19200 instead if your hardware can handle it and you've set S51=5 as described above). It differs from a normal entry in that HUPCL is set (this is generally a good idea for dial-in lines). Next, add the following line or one like it to your inittab: 00:23:respawn:/usr/lib/uucp/uugetty -r -t 60 tty00 BLAZER Now do a `telinit q' from root to start the getty. Finally, use kermit or cu to tell the modem AT S0=1 &W and you're set. This instructs the Trailblazer to auto-answer on the first ring, using as little as possible of uucico's fixed 3-minute timeout. Note: on Microport, you want to use the M-prefixed `modem' devices and an ordinary /etc/getty without -r and -t options. Have fun! -- Eric S.

The April 25 issue of |Data Communications| has an article "A quality comparison: Which carrier tests best?" They tested AT&T, MCI, and Sprint with 9600bps V.32 modems (specifically Codex 2264's). They summarized the results of the tests saying: Despite Sprint's new fiber network, AT&T was still the winner in terms of error-free data connections over all links. Not surprisingly, AT&T also won hands down in terms of call-setup time. [...] In terms of signal loss, Sprint was the winner, showing an average receive signal level of -10dBm [...] But when comparing link by link, there was no clear winner. Besides, all the carriers fell well within the acceptable limits for voice. In their tests, they compared: call-setup time, receive-signal level, and bit and block error rate. Their overall summary for connections with data errors (that is at least one error occured during the 1.5 minute BERT with a 511 pattern) was: AT&T ================ 15% SPRINT ==================== 19% MCI ============================== 29% |---------|---------|---------|---------| 0% 10% 20% 30% 40% "Percent of total tested connections with at least one block errored in transmission."

This tends to send data throughput down the drain. The only tariffed service using compression is M44, which uses the 32K ADPCM speech compression algorithm. It is so named because the 24 8-bit channel bandwidth of a T1 line is allocated as 44 4-bit voice channels and 2 8-bit bundled signalling channels. The ADPCM algorithm has been engineered specifically to support modems. The Europeans had a G.721 ADPCM algorithm months before the ANSI T1Y1 committee approved theirs. What was the holdup? They wanted to get modem traffic right! Turns out that the original algorithm was found to have problems with V.22bis and some patches were made to account for this. The CCITT has since gone back and updated their standard with this same algorithm. There is no compression done at the DS3 level. In practice, DS3 is used in the public network only to multiplex several DS1's. I don't believe that ADPCM is commonly used by carriers for their normal public lines. Even if it were, most modem traffic would be unaffected. (I'm not sure about PEP or V.32.) There are lots of reasons for modem problems, but I don't think this is one of them. The assertion that compression is a problem is possibly qualified by mentioning "resellers". True, there is stuff out there which can make anybody sound like an old 78-rpm record which went through a car wash. But I would think you would have to go out of your way to get a super-cheap economy service to get this kind of stuff. -- Chip Rosenthal / chip@vector.Dallas.TX.US / Dallas Semiconductor / 214-450-5337 ------------------------------ From: Chip Rosenthal Subject: Re: FCC computing device certification Date: 20 May 89 09:11:31 GMT Reply-To: chip@vector.dallas.tx.us Organization: Dallas Semiconductor LANGFORD@crc.crc.vcu.edu writes: >X-TELECOM-Digest: volume 9, issue 168, message 7 of 8 >Can anyone tell me whether PCs MUST be FCC certified Certification under Part 15 is mandatory. >I thought that it had to be certified before it could be sold.

Karmi) ---------------------------------------------------------------------- Date: Mon, 22 May 89 0:33:21 CDT From: TELECOM Moderator Subject: International Reach Out Plans Some discussion here about AT&T's Reach Out Plans recently prompted my contact at AT&T to send me some detailed information about the three international Reach Out Plans currently offered. As you will note, they differ from the plan offered domestically in the United States in the time of day they are in force, as well as how the charges are calculated. REACH OUT UNITED KINGDOM This plan offers 30 minutes of calling per month, for a flat rate of $22.00. Additional half hours are also $22.00, and are pro-rated at 73 cents per minute, which is less than the usual discount rates. Hours for calling are 1 PM to 6 PM, local time, meaning the call arrives in the UK between around 5 PM and 2 AM next day, depending on your exact time zone here. On Saturday and Sunday, the hours are 7 AM to 6 PM both days, meaning calls can be received there between around noon through 2 AM. There is a one time $10.00 sign up fee. REACH OUT PHILIPPINES This plan offers 30 minutes of calling per month, for a flat rate of $35.00 for the first half hour, and $33.50 for each additional half hour. Additional half hours after the first are pro-rated to $1.12 per minute. Again, this is substantially less than the normal rate or discount period rate for calls to the Philippines. Plan hours are Monday through Friday from 2 AM to 11 AM, meaning your call arrives there in the time frame of late afternoon through early morning next day, depending on the originating US time zone. On weekends the Philippines plan allows calls between 12:01 AM and 11 AM; then again between 5 PM and midnight; and after a two hour break, can be resumed beginning at 2 AM Monday morning. There is a $10 enrollment fee here also. REACH OUT ISRAEL This plan is the exception to the bulk, purchase by the half-hour plans. Instead, there is a continuing $5 per month 'subscription charge' which entitles you to purchase whatever time desired during plan hours at a much less than normal or discount rate. Plan hours and rates are as follows -- Monday through Friday: 5 PM to midnight = 85 cents per minute 12:01 AM to 8 AM = $1.05 per minute Saturday and Sunday: same as above, but an additional window -- 8 AM to 5 PM = $1.20 per minute There is no plan discount available 8 AM to 5 PM weekdays. While the UK and Philippines plans do save you money once you amortize the initial one time enrollment fee into your total charges, the Israel plan -- which also has a $10 enrollment fee -- will only save you money if your monthly billings are large enough to absorb the monthly $5 subscription charge and still save money. Based on the few cents per minute difference in the plan rates versus the least expensive economy rates, you would need a couple hours per month of calls to Israel to make it worth while to sign up. Like all discount phone rates, the hours are bound to be somewhat inconvenient for either the caller or the person called, with the exception of Saturday and Sunday calls. And while for the UK plan, persons originating calls from EST or CST zones would probably have the most compatibility in calling at times convenient to the UK, the opposite is true of the Philippines plan, where PST/MST zones would have the greatest flexibility at finding the other end up, awake and available. Regards Reach Out America, I've come to the conclusion that although we in the midwest probably have the most convenient calling window based on either direction of call other than calls straight 'up or down' within your own time zone; the fact is we wind up paying more for calls. At 11-12 cents a minute, calls have to be at least several hundred miles in distance before the rates would be any higher anyway. Folks on the east, west or southern coasts at least have the ability to make calls of greater distances. It reminds of me of the rationale used by telemarketing companies which locate in the middle west: we have the cheapest WATS rates of anywhere; after all, you can only call a couple thousand miles one way, or a thousand the other. Anyway, to sign up for any of the three international Reach Out Plans listed here, call AT&T at 1-800-222-0300. I do not believe there is any requirement that AT&T be your default carrier.

Will >someone from Bellcore or some other authoritative source please reply? PT] While I am NOT AN EXPERT on network numbering, I do happen to have the answer on a reference on my book shelf. ALL possible disclaimers obviously apply! Quoting from Section 3 of "Notes on the BOC Intra-LATA Networks (1986)" (Bellcore document TR-NPL-000275, Issue 1) Paragraph 2.04 "[...] codes of the format N 0/1 X be used as NPA codes except for codes of the format N11, which would be reserved as special functions. This provides a total of 152 area codes as follows. [...]" Paragraph 2.06 "While most N 0/1 X codes are used for the purpose of designating a specific geographical area known as an NPA, a few codes have been assigned for special uses and are known as Service Access Codes (SACs)." Paragraph 2.08 "Currently, there are four NPA type codes assigned in the NANP that are included in the SAC designation. These codes are: 700, 800, 900, and 610 (610 SAC is assigned in Canada for TWX service and is included in this section for completeness. [...]) [...]" Paragraph 4.05 "Currently, only 19 of the 152 usable NPA codes in the N 0/1 X format are unnassigned." [Note: This is 3 year old data. A couple of new NPA codes have since been assigned.] "Five of these 19 are of the format N00, and seem better suited for use as Service Access Codes (SACs) than for use as geographical NPAs. Therefore, the codes 200, 300, 400, 500, and 600 have been reserved for use as SACs and will not be assigned as NPAs. [...]" So, the bottom line is that all N11 and N00 codes are reserved, for the obvious reasons. The N10 codes (except 610) are all included in the unassigned codes. This can be ascertained by looking at the tables of assigned NPA codes, and see which 19 are not assigned. The 610 code is (apparently) used in Canada, so is reserved. --- Michael J.

I think there are two problems here: The answering machine is probably configured/designed to interwork with 1A2 key telephone units, and is shorting the second pair when it answers the first pair. That can probably be corrected by changing the configuration options to "SINGLE LINE" or something like that in the answering machine. If it doesn't have configuration options, modify its cord so that it only connects to one pair. The crosstalk is caused by running two lines in the same quad station wire. Use cables with two (or more) twisted pairs, and the crosstalk should be eliminated. -- Dave Levenson {uunet | rutgers | att}!westmark!dave ...the man in the mooney ------------------------------ From: Dave Levenson Subject: Re: MCI FAX Network Date: 21 May 89 14:12:53 GMT Organization: Westmark, Inc., Warren, NJ, USA In article , lars@salt.acc.com (Lars Poulsen) writes: > It would seem to make no sense at all to maintain a dedicated ... > use it as a price list for my MCI telephone calls ? > If the prices are different for phone and FAX, why ?

It will accept your fax traffic using a fax modem. I don't think it will hear your voice! By compressing a lot of fax traffic into high-speed data packets, they can send it to a dis-assembly system near the destination and then re-sent from a fax modem to the recipient's fax machine.

Covert) Re: Radio Time Sources (Will Martin) Re: My Wife & a cordless phone (Pete Brown) ---------------------------------------------------------------------- Date: Tue, 23 May 89 0:19:16 CDT From: TELECOM Moderator Subject: Pac Bell Gets Okay for 900 Audiotex Prefixes Californians, not normally a prudish lot, raised so much cain with Pac Bell and the California Public Utility Commission over the subject of 'dial-a-porn', that the CPUC has given its blessings to Pac Bell's plan to segregate allegedly harmful audiotex programs on the specially reserved, blockable 900-303 exchange, for which Pac Bell will *NOT* provide billing services. The plan is intended to allow Pac Bell to disassociate itself from offensive programming while simultaneously promoting other 900 services such as sports scores and horoscope readings that are considered more legitimate. Previously, Pac Bell subscribers wishing to block any audiotex programs had to deny service to all programs. Under the new scheme, blocking will be provided free of charge for any subscribers wishing to limit access to the 900-303 prefix for sex lines; the 900-505 prefix for random conference calls; or the 900-844 prefix for the more traditional recorded messages and entertainment services. Blocking will in fact be the *default condition* for 900-303 unless the subscriber specifically requests having it turned on. Under California's revised penal code, passed last year with support from Pac Bell, 'harmful' programming is deemed as any matter which appeals to prurient interests, represents sexual conduct which is patently offensive, and lacks serious artistic and literary merit. As such, it closely resembles the federal code for obscene speech. A Pac Bell spokesman was blunt in his assessment of the matter: "Our goal is to disconnect 'dial-a-porn'. But until/unless we have the legal authority to do that, we've designed out 900 service to solve the problems some consumers have had with 976. Will this plan work? Maybe not. Several information providers, led by Sable Commuications of Los Angeles, are challenging a federal statute for 'obscene' and 'indecent' interstate programming which could well have a bearing on the California law. Sable also notes they believe it is discriminatory for Pac Bell to provide billing services for some IP's while declining to do so for others of whom they disapprove.

[I just went to look this up so I could post the model and be sure I got the facts right, and it seems that my Heathkit catalog here at work has walked off the shelf... Grrr...] It may purport to provide that service, but I would like to point out that reviews of that clock that appeared on the Info-Hams list some years back really panned it. It was most definitely NOT "reliable". The main problem seemed to be that the shortwave-receiving section, which was supposed to automatically tune the best signal from WWV on 2.5, 5, 10, or 15 MHz (don't recall if it tuned 20 MHz) was not very good, and often lost all trackable signals on any frequency. When it did that, it was supposed to switch over to its internal clock and then sync back up when it could receive a trackable WWV signal again. Well, the internal clock was inaccurate! That seems incredible in these days of $5 drugstore watches that keep better time than the finest mechanical movements did a few decades ago, but it seemed to be the case. More than one owner of this clock reported that as a problem to the net. Maybe Heath has improved this model since that time, but I would be VERY wary of putting my trust in it, and slaving automated system-time-setters to this device. There are commercial firms that sell far-more-expensive versions of this sort of time standard, and you really so seem to get what you pay for in this area. The more expensive sets tune the VLF WWVB signals, not the shortwave, so as to avoid the vagaries of shortwave propagation. You might luck out and get a Heath model that works fine, or be skilled enough to tinker with it and tweak it to better performance, but, if you are spending your company's money and not your own, I would recommend going with a professional piece of equipment. As I recall, the bad reviews were not only on the net, but also Radio Canada International's SWL Digest program, which has monthly receiver reviews by Larry Magne, reported these problems also.

PT] ---------------------------------------------------------------------- Date: Wed, 24 May 89 0:36:03 CDT From: TELECOM Moderator Subject: AT&T Strike Likely Over Weekend It is likely that the Communications Workers of America and the International Brotherhood of Electrical Workers will strike the American Telephone and Telegraph Company over the forthcoming three day holiday weekend. Members of the CWA voted overwhelmingly to authorize their leaders to strike AT&T as of 11:59 PM Eastern Standard Time, Saturday May 27, if no agreement is reached on a new contract by that time. The IBEW has been bargaining jointly with the CWA since April 5, and its members will be in sympathy with the CWA in the event a strike is called. The CWA represents 135,000 employees of AT&T; while the IBEW represents 40,000 employees. CWA negotiation representatives say that AT&T is not bargaining with the union in good faith, but AT&T spokesman Herb Linnen said the company is still hoping to negotiate a new contract without a work stoppage. Union officials however say the two sides remain far apart on three major issues: employee contributions to health insurance, pay and job security. T"At this stage, AT&T has yet to seriously address issues of concern to our members," said union President Morton Bahr. "Our unions are detirmined to bargain vigorously and intensively to achieve a contract that provides a full measure of economic justice and job security for our members and their families." The union struck for 26 days in 1986 before agreeing to the present contract which expires at midnight this Saturday night, May 27. Some bitterness remains to this day between CWA and IBEW, which have been bitter rivals in the past. During the 1986 strike, IBEW workers remained on the job, after a promise by AT&T that they would receive any benefits the CWA won through its strike. As a result, AT&T suffered little disruption during the 1986 strike, since about 90 percent of its long distance service is totally automated; and the IBEW workers who remained on the job kept things running, although somewhat sporadically. Morton Bahr has stated that although he has full authority to order a strike at any time after Saturday night, if there is an indication that an agreement is close at hand -- within a few days -- no strike will be called, and the workers will remain on the job without a contract for the interim. But if no progress is made at the meetings this week, then the workers will walk out on schedule, or shortly thereafter. IBEW President John Barry said a strike was '...just one of several tactics' under consideration at this time. Among other tactics being considered is a nationwide boycott of AT&T's long distance service by union employees and sympathizers, as well as other unions in the United States. Bahr and Barry noted that such a boycott would cost AT&T upwards of ten million dollars per month while it was in progress. The boycott plan calls for participants to temporarily switch their long distance calls to Sprint -- which ironically is a *non-union* shop. John Barry noted that the success of such a boycott depended on the cooperation of union members everywhere -- not just CWA/IBEW people. Barry and Bahr said a final announcement on the strategy to be employed; strike, boycott or both would be announced when a decision is reached this weekend whether to continue negotiations with AT&T or break off talks and take other action. AT&T spokeswoman Stacy Dixon said she was confident the dispute would be settled before the weekend deadline. She noted that "...in the past, we have continued to operate with management and temporary workers, and will do so again if we must." Affected by a walkout would be almost every department of AT&T, including long distance operators; business office representatives; technicians and other clerical personnel.

I just signed up for Starlink, a service that is supposed to compete with PC Pursuit. Starlink uses Tymnet's Async Outdial service and offers off peak (7p-6a) calls to BBSes or other online services for $1.50/hr plus phone charges. (charges from the outdial modem) The plus phone charges are what worry me. If you access one of their outdials and make a toll call you get hit with the toll. By "toll" I'm refering not only to typical 1+ long distance calls but the zone charges some phone companys impose on "local" calls. Starlink doesn't seem to know what calls are free from the outdial port and what calls are not. I would think Tymnet would have to know so they could bill Starlink (who in turn bills the user) or there would be a HUGE billing lag, but for whatever reason Tymnet isn't saying. All the user knows is the NPA-NXX of the outdial port. Is there a way to find out whats a free call and what charges, if any, are associated with a call from a remote area. Starlink has made 3 suggestions all of which I don't like.. 1) Go to the library and look at the phone books of ALL of the outdial citys and determine whats a local call. 2) Call the phone co. or operator in the remote city and ask... I have a great mental picture of trying to convince an operator to tell me what zone charges, if any are associated with calls to every NXX from some place other than where I'm calling from. 3) Ask the remote computers Sys Admin. if his site is a local call from NPA NXX (try this with a 15 year old BBS Sysop) Any suggestions of how/where to get this information in a useable form? This seems to me to be another good argument for the "if the calls gonna cost you HAVE to put a 1 or 0 in front of the number (1-976, 1-512-... 011-44-01...)" if the BOC's and independants would adopt this it would save lotsa people lotsa headaches.. no more "I didn't know that 976 call cost $30" just teach the kids not to dial 1+, like my mom did to me. ______ UUCP: ...!crash!pnet01!pro-party!blake ARPA: crash!pnet01!pro-party!blake@nosc.mil INET: blake@pro-party.cts.com Blake Farenthold | CIS: 70070,521 | Source: TCX023 P.O.

Or is this one of This is from memory and may have changed but probably not to much. First of all E911 means two things: 1) an ability to route the calling number to the proper serving PSAP. This means if one house has Police A and Fire A and the next house has Police B and Fire A the 911 call would go to the primary answerer (maybe police) in this case both calls go to poilce A at the PSAP when it is determined it is a fire call all the PSAP attendant will do is press a button labeled fire and the call will route correctly to the proper Fire department .

The PSAP will then do a database lookup the interpret the ANI DN into an address of telephone of the calling party. This information aids in dispatch, redialing, aiding callers who don't know their location. It is an open item today as what to transmit to a PSAP from a cellular phone and how much information is needed at the PSAP - calling number? 10 digits - serving cell? x digits Besides, if the DN to address translation is done at the PSAP from their database, how could they have all the mobile DNs from all over their area translated into their database.

Southern Bell reports that they are running out of central office exchages in the 404 area becuase of an increase of 600,000 access lines (mostly in the Metro Atlanta area). It was reported that SB is doing this because it is a cheap, short term solution and its a prelude to adding a new area code to the area (Metro Atlanta will get its own area code). Programming is in effect now that will allow people to reprogram their auto-dialers and speed calling numbers now. Starting 10/2 calls will not go through and the caller will get one of those wonderful (and usually ear-splitting loud) recordings. They are trying to put off the inevitable.

PT] According to "Notes on the BOC Intra-LATA Networks -- 1986", Bellcore TR-NPL-000275... 700, 800, 900, and 610 are SACs, or Service Access Codes, which are currently assigned. 610, as stated elsewhere, is assigned in Canada for TWX service and is not used in the BOCs; but, as numbering assignments are according to the North American Numbering Plan (NANP), not the US Numbering Plan, 610 is unavailable in the US. The other N00 codes (200-600) have been reserved for use as SACs and will not be assigned as NPAs. N11 codes are reserved for special functions. N10 codes (aha, he finally gets to it) are among the remaining legally assignable NPA codes. As of the publication of Notes, 19 codes of the N0/1X format were unassigned. These included the 5 reserved for SACs, leaving the 7 available N10 codes plus 7 N0/1N codes. I believe the N10 codes will be the last to be assigned as NPAs. Disclaimer: This is taken from the reference; I don't work in Numbering Plan Administration. As far as I know, though, the TR represents the most recent policy (although some NPAs have been assigned since then). -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= David G Lewis "If this is paradise, I wish I had a lawnmower."

The routing function is applied on a number-by-number basis, so that a single exchange may have more than one primary answerer, if the exchange slops over multiple jurisdictions (as many do). In my area in California, we got Police and Fire from two different dispatch centers, (because we use the county sheriff for police, and a neighboring city for fire). The sheriff put up quite a fight to get us to dispatch through the county com center. We finally prevailed, and now all calls go first to fire dispatch. This is because over 2/3 of all calls to fire are for medical aid, and may be life threatening -- so we felt fire response time optimization was more important.

I was driving I5 to Los Angeles, about 50 miles north of Grapevine. Traffic was relatively light. As I approached a slow-moving vehicle in the right lane, I prepared to move momentarily to the left to pass. Suddenly, the other car sped up and when the driver realized that his increase in speed would not in any way prevent my passing him, he suddenly veered into the left lane, forcing me into the median strip. When I got back onto the roadway, I approached him again (he was poking along at around 40 MPH) and he sped up again. This time I backed off and watched as another motorist tried to pass him and got the same response that I had earlier. That did it. I picked up the phone and dialed 911. It was the Bakersfield system that responded and I was connected to the CHP, the initial call handling agency. I described the car and its actions and location. Not five minutes later, two CHP cruisers zipped onto the highway, and off in the distance I could see the gentleman being forced to the side of the road. You talk about instant gratification!

In California, or at least in the San Francisco area, the calls from both cellular providers are handled by the CHP. The operator asks for your mobile number (they don't see it on a display), your location, and type of emergency you are reporting. You are then connected to the appropriate agency. The calls are free of all charges. *All* mobile telephones are allowed to call 911, regardless of roaming or service status. You can even call 911 with a test NAM in your radio. -- John Higdon | P.

Speed" Subject: Routing Incoming Calls on Home Phone I'm experiencing a lot of demand on my "home" phone line; home phones, home office phone, answering machine, modem(s), and a fax machine. In addition, I'm besieged with telephone solicitations. With today's use of telecommunications, I don't think I'm alone in this situation. One solution might be a home PBX, where a caller gets a second "dial-tone" and selects the proper internal line with a touch-tone code (perhaps with a 10 second wait default to the answering machine line). This and roll-over on busy from outside line A to outside line B would go a long way towards congestion relief. I've seen only two "home" type PBX systems advertised so far; one from Nutone in the $1200 range and one from Toshiba in the $400 range. I have requested literature on both; that which was sent to me was inadequate to make any rational decision. Would either of these offer a realistic solution? Are there other systems available? Are they compatible with modems (both 2400 baud and/or Telebits? Are they compatible with (common) fax systems? Are they reliable? What necessary questions am I not asking?

When the voice/tone recognition system detects an invalid (or no) response it simply times out and repeats one or more times. It could say something like, "I'm sorry but I did not understand your answer, I have a collect call from [caller's name], will you accept the call. Please answer 'yes' or 'no' now." After two or more failures to get a valid answer, the call would be routed to a human operator. In a very short time, many people would get used to this treatment and some may even welcome not having to deal with a human when making an operator-assisted call. For the few percent where the automated system doesn't work, those calls would be routed to human operators. Yes, you won't be able to eliminate the need for all operators, maybe only 80%. That represents a HUGE savings. In my humble opinion, there are many reasons automated operators are not more popular. 1. Unions (although being an operator is probably not very interesting, it pays and has benefits). 2. Many people will resent having to deal with a machine (not the ones who use automated tellers). 3. Regulators may need to approve the use of automated operators. 4. It's an expensive technology. 5. Phone companies want the public to know people are behind their network, not impersonal computers. 6. Lack of patience - it takes time to plan, engineer and install automated operators.

This rewiring is the result of a month's complaining about static on one of the lines. The lineman swore he'd replace the junction box with a style that allows for isolating the internal wiring UNTIL he discovered a loose connection in a telco distribution box. With the new junction box, connecting the box's ground to a "ground line" running along the boardwalk induces an annoying hum on one and one of the three lines - the other two are not affected. The lineman that responded to the hum complaint is convinced my computers are causing the problem. Nevermind that the two lines that *do* have computers (modems/fax) on them are NOT affected! The voice line has three regular phones and one feature phone on it. Obviously a fault in my wiring or the feature phone could cause a hum, but an MSEE and 25 years electronics experience doesn't give me any idea how my wiring or equipment would cause a hum that depends on the grounding of the phone company's arrestor block. Faced with a choice between an aggravating hum and leaving the ground off, I told the lineman to get rid of the hum.

Lowe) Re: More TSPS ANI confusion (Nicholas J. Simicich) ---------------------------------------------------------------------- Date: Mon, 29 May 89 10:37:42 CDT From: TELECOM Moderator Subject: AT&T, Unions Resolve Differences AT&T and its major unions, the International Brotherhood of Electrical Workers and the Communications Workers of America, announced agreement on a new contract Sunday that both sides said provided a radical change in family care benefits. A tentative contract was announced late Saturday night, just minutes before the strike deadline. With the major difference of health care being resolved, negotiators for both sides agreed to extend the old contract on a day by day basis, to give them time to resolve several minor issues. The new three year contract covers 135,000 members of the CWA and 40,000 members of the IBEW, who bargained jointly with AT&T. CWA President Morton Bahr, speaking on behalf of both unions shortly after the final agreement was reached, called the new contract 'an unprecedented breakthrough in labor-management relations with respect to family care.' AT&T Vice President Raymond Williams agreed, saying, "This contract is the most progressive ever negotiated by AT&T." AT&T went into the negotiations April 2 wanting to share some of its health coverage costs with union members. It said health coverage for employees was costing one billion dollars per year. The plan finally agreed upon does not shift any of the cost to employees. The new agreement also contains innovative provisions on child care and care for elderly parents, as well as improving pay and profit-sharing plans. An AT&T employee is now paid an average of $500 per week. The new contract will give them a lump sum payment ranging from 4 percent to 8 percent, with annual increases from 2.25 percent to 3.5 percent, based on skill levels. Bahr noted that AT&T Chairman Bob Allen had said a company goal was to prove that a unionized telecommunications firm could compete against non-union firms, and the agreement was a response to that. AT&T's two major competitors in the long-distance calling business, MCI and Sprint are both non-union, as is its rival in computers, International Business Machines. The new agreement also provides one-year unpaid leave for newborn or adopted children and improved benefits for those persons on leave. Only time will tell what effect all these changes have on rate-payers across the country. If AT&T can buffer these additional expenses without any impact on the costs passed along to customers, all well and good. Supposedly, according to Morton Bahr, they can do so. Patrick Townson ------------------------------ Date: Mon, 29 May 89 11:04:14 CDT From: TELECOM Moderator Subject: New Enhancements From the BOC's Three of the Bell Operating Companies have started new innovative services in recent weeks. Here is a summary of each -- MICHIGAN BELL now allows customers in several suburban Detroit communities to order Touch-Tone service and Custom Calling features on a trial basis using an automated dial-up system that turns on the services within minutes. The service is available 24 hours per day. The system provides ordered services within 15 minutes, according to the telco, compared with the previous waiting period of up to 48 hours. The service is accessed by dialing an 800 number, and features recorded information and prompts for users of tone-dial phones. The trial is scheduled to continue until the end of the year. About 200,000 customers are in the test area. BELL OF PENNSYLVANIA now is offering something called 'I.Q. Services', which is a combination of Custom Calling and CLASS services into a single personal call-management system. I.Q. enables subscribers in the Philadelphia area to redial busy/no answer numbers automatically, block unwanted incoming calls, assign a special ring to selected numbers, forward only on selected calls, and initiate a trace. Custom calling services of course include call-waiting, three-way calling, call forwarding and speed calling. CLASS call-management services include return call, priority call, repeat call, call block, select forward, and call trace. The CLASS offerings *do not* include caller identification service at the present time, as this feature is subject to Pennsylvania Public Utility Commission review at the present time. SOUTHWESTERN BELL has begun a telemetry trial that allows utilities to read home utility meters over a single telephone line. The test is being conducted at about fifty homes in Kansas City, MO. Water and gas meters at each site are equipped with meter encoder/digitizers that link to a telemetry interface unit at each home. Readings collected at each site are sent over the telephone line to meter reading access circuits at a Southwestern Bell central office, which relays the readings to computers at the gas and water company offices. The system delivers a reading in about ten seconds, and automatically disengages if the subscriber is using the phone. Southwestern Bell also announced they have signed a contract with MCI to provide billing and collection services for MCI's long distance service, beginning in the fourth quarter, 1989. Southwestern Bell subscribers in that company's five-state region who opt to use MCI will begin seeing long distance charges from that company on their October, 1989 phone bills.

(At least, IMHO.) Well, traditionally, one benefit of spending the extra money for a person-to-person call was that you could leave a message to call a certain person back at a certain number, free, if that person wasn't there. I suspect that the theory was that it would add to the revenue of the phone company when that person called you back. Once the decision has been made to support person-to-person calling, the provider of that service has opened themselves up to people passing messages via code, assuming that you were willing to cheat the phone company by building a code list of people to call. So allowing "Joe" to know that "Karen" called and wants to be called back at NXX-4315 simply means that three code words can be communicated in one call rather than three calls, one for "Joe", one for "Fred", and one for "Sam". Assuming the honesty of the individual, it only makes sense for them to allow people to leave a number where they can be reached. In this case, I would have called back, gotten another operator, asked them to place another call and correct the message. Failing that, I would have asked to speak to a suporvisor. But I almost never call person-to-person anyway. -- Nick Simicich --- uunet!bywater!scifi!njs --- njs@ibm.com (Internet) ------------------------------ End of TELECOM Digest V9 #178 *****************************   Date: Tue, 30 May 89 7:50:19 CDT From: TELECOM Moderator To: telecom@eecs.nwu.edu Subject: TELECOM Digest V9 #179 Message-ID: <8905300750.aa18407@delta.eecs.nwu.edu> TELECOM Digest Tue, 30 May 89 07:37:30 CDT Volume 9 : Issue 179 Today's Topics: Moderator: Patrick Townson Re: New Enhancements From the BOC's (Scott D.

In fact, on their in-house newsline last week, they felt it necessary to warn their employees of exactly that, suggesting that customers may be in for a shock when the bills come in. Bell asked their employees to tell their kids not to play with the IQ services. Is it really fair, though, for the BOC's to offer these value-added services to a customer's line without his or her consent or even knowledge? Is this something akin to the flap over 976- services, which led to the BOC's offering no-charge blocking of these numbers as well as placing the racier material on exchanges that require advance sign-up in order to access them? Where is the PUC? Is this arrangement a concession to Bell of PA, because of the investigation of the CallerID service (proposed at $6.50/month)?

In most jurisdictions, the telephone company is obligated by tariff to provide as many lines as you want to your Network Access box for no more than the standard turn-on charge per line, whether there are wires already in place or not. If they have to pull an extra wire, the cost is averaged in with the costs of all the other hookups where they charge you $50 for nothing more than making a few entries at a terminal to turn on an existing line. They may choose, of course, to multiplex (FDM or TDM) several circuits on one wire if they decide that is cheaper. My guess, however, is that they will find it much less expensive to simply pull a new wire from the junction box to your house, and that they will do just that if you order a third line.

Trust me, you *don't* want that! It is known as "subscriber carrier" and is General Telephone's answer to undercapitalization. They use a device that multiplexes a second subscriber on a telephone pair by means of a supersonic carrier. If you are the metallic subscriber, there is little problem. If you are the carrier subscriber, your telephone service isn't worth the powder to blow it up. The unit is "phone line powered", which means that it sits there and trickle-charges its nicads during the metallic subscriber's on-hook periods. If he talks a lot, or the carrier subscriber gets a lot of calls (the device has to supply ring voltage), the batteries run down and phone service phades away. The audio is terrible, and there is no loop current signaling for answering machines, etc. I suspect that our various telcos (General being the worst) never anticipated the "information age" and felt that planning for two drops per housing unit would be more than adequate. Although no one at Pac*Bell has said anything, I suspect that my nine lines have put somewhat of a strain on the neighborhood facilities. My friends in southern California (who are served by General Telephone) marvel, not just at being able to get nine lines, but at the fact that they're all metallic. To the best of my knowledge, none of the BOCs have used subscriber carrier. And for good reason. > I would need independant lines for modems, fax machines, etc. > Any ideas of pricing? What's the service officially called? The service you want is "enough pairs to serve your needs". You will (probably) have to do a little trenching yourself, but it's the only real solution.

What convinced me to try Starlink was the fact they are now $1.50 / hr and have _cancelled the excess kilocharacter charges_ They also now go to a boat-load of cities. In Texas PCPursuit only goes into Houston and Dallas/Ft. Worth. Starlink goes into Ammarillo, Arlington, Austin, Corpus Christi (my home town!), Dallas, Denton, El Paso, Ft. Worth, Houston, Killeen, San Antonio, and Waco. Starlink does, however maintain the 5 minute minimum per connection. This could add up in a hurry if you are trying to call a busy host system. If they'd do away with the 5 min minumum and give you the first minute free (so if the bbs is busy you can disconnect w/o incurring a charge) I'd dump PCP all together.

In fact in school when the teacher claimed 'pies are squared' I told him he was a liar; that all the pies I have ever seen were round. But be that as it may, if Telenet charges $30 for 30 hours, that comes out to $1 per hour in my handy TI-58 calculator. And at $50 for 60 hours, that comes to 83 cents an hour. A dollar per hour or 83 cents per hour is less than $1.50 per hour. Unless or until you use more than 60 hours per month -- more than two hours per night each night of the month -- Telenet is still cheaper on an hourly basis. But that is not all. Those first 60 hours cost $50 on Telenet versus (60 x 1.50 = $90) on Starlink. The next 30 hours on Telenet cost ($3 x 30 = $90) versus ($1.50 x 30 = $45) on Starlink. So after 90 hours per month on the modem -- 3 hours per night -- we have spent $140 on Telenet versus $135 on Starlink. So 'savings' on Starlink don't even enter the picture until after around 88 hours per month. That is an awful lot of time on line for those of us who also work 40 hours a week and sleep a few hours each day. Finally, Telenet allows you to purchase multiple accounts; that is, 2 'family' accounts at $100 per month for 120 hours, or 3 at $150 per month for 180 hours, etc. PT] ------------------------------ Date: Tue, 30 May 89 16:15 EDT From: Jeffrey Bary Subject: TC Institute TELECOMMUNICATIONS IN HIGHER EDUCATION Seventh Annual Institute June 12-15, 1989 WHO SHOULD ATTEND Faculty and administrators who are using or wish to introduce telecommunications in their institutions.

PT] ---------------------------------------------------------------------- Date: Wed, 31 May 89 14:40:10 CDT From: Will Martin Subject: Dave Barry on Call Waiting Though you might like to see this, which came over the "dave-barry" mailing list: [05/06/89] An Invention That Really Clicked by Dave Barry Today I want to *click.* Excuse me. OK. Today I want to talk about *click.* Excuse me again. OK, where were we? Oh, yeah, I was saying that *click.* Never mind, just ignore it. I was saying that I want to *click* about this major stride forward in *click*phone technology called "call waiting," which is such a big *click*ing *convenience* that I'd like to find the *click* who invented it and ... No, wait, let me just calm down here. Some readers may not even know what I'm talking about. Some readers are probably living in backward, soybean-infested regions that don't even have the incredible convenience of "call waiting." So let me explain how it works: If you're on the phone with Party A, and Party B tries to call you, both you and Party A will hear an interruption noise, which alerts you to press your disconnect button so you can talk to Party B, who trust me has absolutely nothing important to tell you, so you say you'll call back and resume talking with Party A for 10 full seconds, until you hear another interruption noise indicating that you have a vitally unimportant call from Party C, and so on down the alphabet until Party A decides to drive over to your house and strangle you with your phone cord. Doesn't this sound terrific, soybean people? Doesn't it sound *modern?* To give you a clear picture of what you're missing, let me compare "call waiting" to an everyday domestic situation. Let's say I'm having dinner with my wife and 8-year-old son, and my wife and I are discussing the kind of important issue that normal, mature married adults discuss at dinner: ME: It does *what* when you flush it? MY WIFE: It makes kind of a banging sound. ME: A *banging* sound? MY WIFE: Yes. And there are these little like electric sparks coming... OUR SON (interrupting): How come... MY WIFE: Robert, please don't interrupt. ME: Sparks? MY WIFE: Yes, and they're... OUR SON (interrupting): But I was just gonna ask you... MY WIFE: Wait, Robert! ME: There are *sparks?* MY WIFE: Yes, they're coming from... OUR SON: But this is *important!* MY WIFE: *ALL right,* Robert. What *is* it? OUR SON: How come my left arm tastes saltier than my right arm? "Call waiting" is very similar to this. It's kind of like an electronic 8-year-old who is simply incapable of shutting up while you are conversing with somebody else. The differences are that (1) an 8-year-old does not have the gall to charge you a monthly fee for this service; and (2) an 8-year-old can interrupt you only if he's in the same room, whereas with the incredible capabilities of "call waiting," your conversations can be interrupted by *everybody in the entire world who has access to a telephone.* It doesn't even have to be a person. A computer can interrupt you. In fact, through a combination of "call waiting" and "auto-dialing," it is now technically possible for your telephone conversations to be interrupted by a *trained chicken.* And whom do we have to thank for this amazing communications breakthrough? My guess is that it came from the prestigious Institute of Irritating Technology, whose hard-working staff of former Nazi medical researchers also developed: the beeper; the non-openable fast-food ketchup packet that contains a total of four ketchup molecules; the machine that inserts those hateful little cards that are forever falling out of magazines; and the empty self-service elevator that for no apparent reason closes its doors just as you get to it, then emits a clearly audible computerized chuckle. But I think the boys at the institute really outdid themselves with "call waiting," although I should point out that we don't have it in our own household. We feel that we can obtain the same benefits, without the monthly service charge, by simply whacking ourselves with hammers. But it seems as though almost everybody we know has this powerful feature, the result being that we have learned to speak in very short sentences, which we squeeze between the clicks ("What's new?" *click* "Mom's dead." *click* "Too bad!" *click*). It's just so darned convenient that I can hardly wait to see what exciting new services the telephone people will come up with next. Maybe they'll offer "Call Fabricating," wherein your phone becomes bored and rings for no reason; or "Call Misrepresenting," wherein your callers' voices are electronically altered so that you hear the *opposite* of what they actually said ("Mom's Dead." *click* "Great!" *click*). But what I, personally, would like to see -- call me a dreamer -- would be some kind of service wherein if you were talking to somebody, and a third person tried to call either of you, *your call would not be interrupted.* Instead, the third person would hear a special tone -- we could call it a "busy signal" -- telling him that a conversation was already in progress, so he'd have to try again later. But I doubt we'll ever see this come about. The concept is far too complex to be grasped by a certain type of telecommunications consumer. I am thinking primarily of the chicken. ----- End ----- ------------------------------ Date: Wed, 31 May 89 16:49:46 PDT From: John Gilmore Subject: Re: New Enhancements From the BOC's > *57 Call Trace $1.00/use > *60 Call Block $.50/day or $5/month > *61 Distinctive ring (up to 6 #'s) $.50/day or $2.75/month > *63 Selective Call Forwarding (up to 6 #'s) $.50/day or $3.50/month > *66 Auto Redial $.25/use or $1.75/month > *69 Return Call $.25/use or $2.50/month Gee, I knew the price of DRAM was high, but 50c/day for a few bytes?

It seems to be used quite often in automated telephone systems, where the user is told to follow some code or other with 'the pound key'. In the UK the '#' symbol is generally called a 'hash'. I wonder if this confusion over nomenclature caused the REAL pound sign to be missed from that ASCII character set altogether.

"Pagers don't commit crimes, Congressmen do." From: rgt@beta.lanl.gov (Richard Thomsen) Newsgroups: talk.politics.guns Subject: The future is now - future bans are being considered Keywords: drugs, beepers, bans Message-ID: <25244@beta.lanl.gov> Date: 30 May 89 19:16:49 GMT There were some articles guessing what would be banned next, after guns were banned and did not have an effect on the war on drugs. I was given a copy of _USA_ _Today_, and saw a "face-off" on the issues. According to this article, Representative Kweisi Mfume (D-Md) says the following (reprinted without permission, spelling errors are probably mine): The drug business is using the latest technology to promote its deadly trade. One such advance, the paging device, or beeper, is now appearing in classrooms and schoolyards. I have introduced the Beeper Abuse Prevention Act to curtail the use of beepers by young people who deal drugs. It would require the Federal Communications Commission to prescribe regulations that would restrict the possession and use of paging devices by persons under age 21. Law officers say dealers and suppliers send coded messages via beeper to youths in school. The codes translate into messages like "meet me at our regular place after class to pick up the drugs." Drug traffickers are even using 800 numbers now available with regional paging services. A supplier could actually conduct a transaction in Baltimore from Miami, for example. My bill, H.R. 1504, would require any person selling or renting paging devices to verify the identification and age of every customer; encourage parents and businesses to take more responsibility in their children's or employees' activities; make it unlawful for a person to knowingly nad willfully rent, sell or use paging devices in violation of rules prescrived by the FCC (there are provisions for stiff fines and up to three- year prison terms for adults who illegally provide beepers to youths); and require parents or businesses who allow the use of beepers to state that intention with and affidavit at the time of purchase. He goes on to say that he recognizes that there are legitimate uses of beepers, but we can no longer stand by and watch drugs flow into our neighborhoods. The opposite side is taken by Lynn Scarlett, from Santa Monica, CA. She asks what beepers have to do with the drug trade, and regulating their use will not put a dent it it. She also says that there is little evidence that gun control keeps guns out of the hands of gangsters, and it will take a good dose of wizardry to keep beepers away from bad guys. She finishes with: The logic of the Beeper Abuse Prevention Act opens the door for laws to make us sign promises that we won't, we swear, use these things for illicit acts when we buy them. De Tocqueville, that eminent observer of our nation, waned that our loss of freedom would sneak in through passage of quiet, seemingly innocuous and well-intended laws -- laws like H.R. 1504. So all of you who were guessing the next thing to be banned did not guess the real truth. I saw no guesses that it would be beepers. Before you ask, I cut the article out of the newspaper, and did not cut out the part that shows the date of the paper. But it was last week, which means from 22 to 26 May. It was probably the Wednesday or Thursday (21 or 22 May) issue, on the opinion page at the bottom. ------------------------------ Date: Wed, 31 May 1989 16:35:55 EDT From: Jonathan Alan Solomon Subject: MCI fraud ATTENTION MCI 800 service people. Apparently MCI is unable to disconnect 800 service right now. Apparently they can create new 800 numbers, but once a number is in the database, it is permanent and they can't disconnect it. The problem I face is the legal implications of that problem. I was an 800 service customer, and I now have my 800 numbers on my residence lines. I previously disconnected one of them, and had to reconnect it because it became clear that MCI would be unable to disconnect them. That cost me $35.00 or so from New England Telephone (I happened to disconnect one of my numbers to get that line back, so they didn't have to send out an installer.)... I reconnected that line because they are still billing me for the service, even though I disconnected it, and even though one of the MCI people insisted that I wasn't responsible for the lines. I believe she didn't have authorization to say that, and now MCI is trying to back out of her agreement with me. Sending me the bills is there way of keeping track of what the usage is, which is their way of covering their ass. As for usage, I don't mind paying for what I use, I'm not into fraud, but they are continuing to bill me the $20.00/line maintainence fee as well. I think they think I am still responsible for the lines, which means the girl at MCI lied to me. Either way I'd like to get a statement from MCI directly, either that I am responsible for the bills or not. If I am, I'd like them to tell me that in writing. If I am not, then I'd like them to tell me that in writing. Can anyone out in TELECOM land help with this? When I dial the MCI main number, and ask to talk to *anyone* I always get their MCI VOICEMAIL mailbox, or some secretary. They NEVER let you talk to anyone. I need a *good* lawyer to deal with this. Recommendations? Apparently there is no place within the MCI structure to resolve complaints. I guess they think they are perfect. I signed up for MCI's competetion to reach-out-america service (don't know what they call it, sigh), twice. The first time they said it would be ready June 1st, the second time was on june 1st to ask them if it was up. It was not even in their computers. They took the information again and now I am waiting for NET to switch my carrier. I hope MCI gets their act together soon, they have the potential to be an excellent asset to the international telecommunications systems. BTW: My 800 numbers are gone, looks like persistance paid off. --jsol [Moderator's Note: Jon Solomon was the founder of TELECOM Digest and the original moderator here for several years.

Other cases where a state has 2 area codes, one of which got N0X/N1X prefixes: New Jersey, areas 201 and 609; 201 got N0X/N1X, and the new dialing require- ments also applied to area 609 for statewide uniformity (and later, two N0X/ N1X prefixes were made local to Barnegat, in area 609). Virginia, areas 703 and 804; 703 got N0X/N1X, apparently limited to the DC area suburbs (all but the outermost ones also being reachable in area 202). 804 did NOT get the new dialing requirements (however, DC and Maryland did, so that 703, 202, and 301 all now dial long-distance and 0+ calls the same way).

The problem is that 1+ is recommended for use to distinguish 7-digit dialed numbers from 10-digit dialed numbers where interchangeable NPA/office codes are introduced (currently only a few locations; will eventually be very widespread because of code exhaustion). Some 10D calls are "local" calls; some 7D calls are toll calls. Example: You live in Queens (NPA code 718) and are calling someone in Manhattan, 212-NNX-XXXX. It's a "local" call, though. If 1+ means a toll call, the switch has to have some other way of recognizing that 212NNXX is not a home NPA dialed number -- it has to wait and expect more digits after the first 7. So when you call someone in Queens, say at 218NNXX, the switch has to wait four seconds or so in case you're really dialing someone at 218-NXX-XXXX (your buddy in Minnesota). If 1+ means a 10-digit dialed number, the switch can interpret the first digit; if it's a 1, it leaves the tone generator on line until it gets 10D; if it's anything else, it takes the tone generator off line and gets on with call processing after getting 7D. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= David G Lewis "If this is paradise, I wish I had a lawnmower."

It sounds like the CO is no longer accepting tone dialling on this line. On 5ESS exchanges, there is a status bit to indicate tone service, and if tone service is turned off, it will behave as you describe. The phones are okay. Tone dialling is an extra-cost option - $1/month/line in most areas. Most BOCs have implemented the blocking for subscribers that don't pay for it by now; used to work whether you paid for it or not, but they might start billing you if you used it. -- / Lars Poulsen (800) 222-7308 or (805) 963-9431 ext 358 ACC Customer Service Affiliation stated for identification only My employer probably would not agree if he knew what I said !! ------------------------------ Date: Thu, 1 Jun 89 20:22:40 PDT From: hughes@bosco.berkeley.edu Subject: Re: Strange Phone Problem Organization: UCB Mathematics Department In article the author writes: [Moderator's Note: See first item for problem description] Many AT&T phones will not dial when the polarity of the phone line is reversed.

If my company has 30 incoming lines, all hunting to each other, and disappearing into a big black box anyway so they can't be reasonably identified from one another, -- do I need thirty DIALABLE numbers assigned to me? One will do, and in my local CO, the switch can say to itself: "There's got to be a xxx-xxxx around here somewhere I can connect this call to." Of course the other circuits would have identifiers for tracing and troubleshooting and all that, but the public network doesn't need to know about how many circuits there are, only the local CO. Usually, these extra numbers aren't listed anyway. I realize this plan falls flat for Centrex-type direct inward dialing services, but (sorry telcos) this isn't the majority of use (at least not yet?). My guess is that it would free up at least 30% of the dialable capacity nationally, and closer to 50% in metro areas (like Atlanta;-). Comments?

We bought a Southwestern Bell Freedom Phone 1700 in January '88 and have been very pleased with it. The batteries are user-replaceable, it has 10 user-selectable channels, user-selectable security codes, a speaker phone on the base, you can dial from the base or the handset, and you can store up to 10 numbers in the handset for auto-dialing. I had a problem with interference from a baby monitor, so I just changed to a different channel and haven't had a problem since. The antenna is replaceable also. But to avoid having to replace a broken one, just go to Radio Shack and get a flexible antenna for about $5. That has saved me a lot of grief. My mom and both sisters have had lots of problems with the older ATT phones - the 4400 series. They give false rings, are prone to interference and they cut out a lot. Avoid them at all costs.

I have been looking in to the pricing alternatives for him for switching to single party service, since a Rabbi and his wife are also on the same line and talk for 3 or 4 hours at a time. NET charges about $3.50 per month for the service, which we can't complain about... My dad is willing to pay the extra $4.26 per month for private service, but does not want to pay $32 for the privilege of conversion. One interesting thing came up in the conversation I had with NET. The CO is supposed to become an ESS (probably a satellite off a 5ESS) in 1992. During the year prior to the conversion, the 4 party lines are eliminated by offerring 2-party lines, single party timed, or single party unlimited service. It seems there is no way to support 4-party service on an ESS. I was surprised that a 2-party service would work. (With party lines it is required by law that you be able to hear the other party talking when you pick up the phone -- so that you can tell them to get off in an emergency). During the conversion period, NET will do the conversion free. I'm somewhat surprised that they don't just do it for free now if desired. The party line service is responsible for at least 5 service calls a year of the variety where they need to come out on a Sunday (all summer cottages). The best service call was to CUT the line to one of the other houses when they plugged in an answering machine... All long distance calls are operator assisted, since it is not possible to determine which house is originating calls.

ZIPPHONE is composed of the following files: ZIPPHONE.EXE ZIPSTATE.DAT NPAxxx.ZIP (where xxx is an NPA) -----------------------> For Programmers <------------------------ The ZIPPHONE data files that contain the NPA-NXX to Zipcode translations (npaxxx.zip) are in Binary Coded Decimal (BCD). Consequently, other programs cannot directly access the information contained therein, unless the program uses a programming language such as C Language which provides bit manipulation facilities. The BCD format produces a 70% disk space reduction over the ZIPPHONE format in Option 10, and the format also decreases execution time by reducing disk I/O. The information in the NPA BCD file is sorted by NXX and ZIPCODE. The general format is: NXX First digit of the valid zipcodes for the NPA Number of Zipcodes for the NXX List of the Last 4-digits of the Zipcodes for the NXX Specifically, for each NXX in the NPA BCD file, the format is: bits 4-7 of byte 1 = 1st digit of NXX bits 0-3 of byte 1 = 2nd digit of NXX bits 4-7 of byte 2 = 3rd digit of NXX bits 0-3 of byte 2 = 1st digit of Zipcodes for this NPA bits 4-7 of byte 3 = tens digit of no. of Zipcodes for this NXX bits 0-3 of byte 3 = ones digit of no. of Zipcodes for this NXX For each ZIPCODE for the NXX, the format is: bits 4-7 of byte x = 2nd digit of a Zipcode for this NXX bits 0-3 of byte x = 3rd digit of a Zipcode for this NXX bits 4-7 of byte x+1 = 4th digit of a Zipcode for this NXX bits 0-3 of byte x+1 = 5th digit of a Zipcode for this NXX where 'x' starts at byte 4 is increased by 2 for each Zipcode for the NXX.

Or is it something that AT&T gives away, like those little pocket phone directories? Then my second question: where can I legitimately obtain more up-to-date data of this sort? I have heard about the V&H tapes; I gather that they contain city names and location coordinates for all NPA-NXX's. I would like to have that kind of data to play with. I have the impression that the tapes themselves are rather expensive. Since I don't require the most recent edition for my casual personal use, would it be feasible to get it "second-hand" somewhere? I'm a programmer, so I'd be more interested in having raw data to build my own applications than in buying a commercially avaliable software/data package. Some of the things I'd like to do with this data are: plot maps of phone numbers, check that phone numbers match addresses, estimate long-distance charges, and the like. wayne hamilton U of Il and US Army Corps of Engineers CERL UUCP: {convex,uunet}!uiucuxc!osiris!hamilton ARPA: hamilton@osiris.cso.uiuc.edu USMail: Box 476, Urbana, IL 61801 CSNET: hamilton%osiris@uiuc.csnet Phone: (217)333-8703 ------------------------------ From: "John R.

This is a complicated question -- there are over four hundred different sets of rates depending on location, and they vary drastically, from incredibly low rates such as Washington, D.C., with a $10/month off-peak rate INCLUDING 100 minutes of off-peak usage to very high rates such as in L.A. with $45/month and no minutes included. Since you're in Boston, you would probably take service from NYNEX Mobile or Cellular One (Southwestern Bell). NYNEX rates are: (monthly - peak minutes - off-peak minutes) A: $19 .45 .30 B: $45 .35 .30 C: $ 5 .65 .65 D: $9.95 .60 .25 (best plan for non-business users) E: $44 .45 .30 includes 60 minutes peak On outgoing calls, in addition to air time, you pay the same rates a business telephone user would pay. For local calls, this means that you pay for a local call from one of: Boston, Providence (RI), Worcester, New Bedford, Framingham, Brockton, Lynn, Lowell, or Lawrence regardless of where you are in the three state area (Eastern Mass, Rhode Island, Coastal New Hampshire). Local calls are charged in message units of .111 cents each, and for calls to places local to multi-message unit towns, such as Burlington (charged from Boston) you'll pay .333 cents for the first three minutes and .111 each additional minute (same as from a Boston phone). For non-local, intra-LATA calls, you'll pay the toll charge from the closest points. Since I have a Boston number, I don't know whether all inter-LATA toll is charged from Boston or if it is charged from the zone office (one of the nine above) which corresponds to your mobile number. When you're roaming in the Nashua/Manchester (Contel) system, the Biddeford, ME (Star Cellular) system, or the Portland, ME (Maine Cellular) systems, you'll pay .45/minute regardless of time of day. Note that you are _not_ roaming in Southern Massachusetts if you're a NYNEX customer; it is one continuous system. NYNEX has nationwide roaming agreements with mostly B but many A carriers, allowing you to choose the lowest rate and best service in many other cities. In particular, in New England and the Northeast, you are less likely to be hit with daily usage fees when roaming if you're a NYNEX customer. You'll also have roaming agreements with companies in San Francisco and Los Angeles, which Cellular One does not currently have. Cellular One rates are: $19 .44 .29 $44 .43 .28 w/ 60 $59 .42 .27 w/ 100 after 300 mins .35 .27 The points of interconnection for Cellular One are: Lynn, Lawrence, Waltham, Framingham, Worcester, Quincy, and Brockton When roaming on the A carriers in Nashua/Manchester, Biddeford, ME, Portland, ME, New Bedford, MA, and Providence, RI, you pay .44 and .29. When roaming outside this area, you will have roaming agreements with mostly A and some B carriers. You will be more likely to encounter daily fees, especially in the Northeast. Please realize that charging algorithms vary drastically from company to company and from city to city. For example, Contel in Nashua/Manchester does not charge a local call or toll call charge for anywhere in either their system or in the NYNEX system, even when roaming (or so I'm told by their customer service department). U.S. West in the Seattle area charges you for outgoing calls based on where you are and where you're calling within the area. Rates are changing faster than anyone can keep up with them (mostly going upward as fast as the market will bear). /john ------------------------------ From: "Gary W.

They work fine for incoming calls, The problem is most likely due to the reversal of the pair. To check this, open one of the ATT phones and exchange the red and gree wires where they enter the phone and are first attached. ATT made the phones sensitive to the polarity of the phones once-upon-a-time. This allowed the RBOC to flip over the line to keep people who did not order Touch-Tone from using it. Of course the breakup changed all of that... If your friend does not pay for TT service (and nobody should have to...) then just reverse the pairs. Most other telephone manufacturers put a diode bridge in the telephones so that polarity didn't matter. The ONLY negative impact that I have found is that telephones with the diodes require modification to work on party lines. -- Daniel Senie UUCP: harvard!ulowell!cloud9!dts Stratus Computer, Inc.

Since the AT&T phones are leased, return the phones and get new ones (I think at no cost).

The 5200 is very similar, but doesn't have the intercom feature and the 5310 adds a memory dialer and extra phone cradle to the 5300 features. At the local phone center I also saw a new 40xx series phone that has the looks (and supposedly the voice quality) of the 5xxx, but its cheaper. However, I can find the 5xxx models at a lot of stores and the new 40xx was only in the phone center, at straight list price. They also had the 5200 at a lease to buy price of about $20 a month for 6 months, but didn't offer several of the better models under the lease to buy program. My 5300 has very good voice quality and so far has been very durable. I dropped it twice on a ceramic tile floor and managed to break the antenna, but the shell and the electronics survived without any problems. The 5300 has a poor design for wall mounting because the line cord and AC cord end up on top and you have to route them down and around the phone base. The phone base needs its own wall mount (included) because it won't fit on a standard Bell wall mount (is this too much to expect?). The handset also doesn't catch very well in the cradle when wall mounted, which is why I have dropped mine twice while hanging it up. Based on quality I would buy another AT&T phone, but they could use a little more work on ergonomics and general design features.

I've noticed that on newer exchanges, mainly DMS-100 (-200?) and 5ESS niether party hears a click. The called party hears only a beep, while the person talking to the called party hears nothing. Only if the person who gets the Call Wait is talking or if there is a lot of noise in the background will you hear a small gap of silence while he receives the Call-Wait tone. This is pretty nice, but it also means that you can't tell if the person who is Call-Waiting you has hung up or not (ie, you don't answer the Call-Wait.) On the an older ESS, you would hear a final "click" after the person calling you would hang up. On a DMS (and I presume 5ESS, although I never tried it), you only hear the two Call-Wait tones, and that's it. The person Call-Waiting you could stay on the line and keep ringing for hours, and as long as you were still talking, you'd never know, and may miss other Call-Waits. (Silly, but it can happen...) (DMS's do other weird things, like not let you make a 3-way call until you connect to your other party, even if it's long distance. Most older ESS's only do this locally (or only to 'tandem' exchanges?) so if you call someone in Toronto (assuming you don't live there) and he is busy, you can 3-way that call with someone else. (Again, silly, but you may want to for some reason...) On a DMS, it *knows* you didn't complete the call, and won't give you the three-way tone, and will just drop the Toronto/busy call and give you a dial tone. I guess it all depends on how much info the switch is given... If has a way to test for call completion, I guess it uses that info when processing 3-way calls... ) Anyhow, have fun with Call-Waiting! -Doug dreuben@eagle.wesleyan.edu dreuben%eagle.weslyn@wesleyan.bitnet (and just plain old "dreuben" to locals! :-) ) (I hear the local count reading these is up to 3!!! wow!) ------------------------------ Subject: The Term "Touchtone" -- No Longer Protected?

A telecom-related point came up in the news coverage of the recent troubles in Beijing over this past weekend. When describing and playing back the tape of the incident where the troops took the CBS correspondents into custody during the clearing of the square, Dan Rather referred to the audio feed as coming from "a cellular telephone" on at least two separate newscasts. This sort of surprised me. Does Beijing have cellular telephone service? I would have expected them to have some form of mobile telephones, but maybe only for official government use, not available to foreign correspondents or even ordinary citizens. I certainly may be wrong in that supposition, though. Having cellular phone service readily available just doesn't seem to me to be that likely. Also, that it was still working during that period is surprising; I would have thought the telephone service would have been shut down by the Army. Just how worldwide IS cellular telephone service implemented? I didn't think it even was available all over Europe yet. Where in the Third World can one use a cellular phone, and are all the systems interchangeable and compatible? Or would what the CBS correspondents had been using have been some system that they took with them and installed themselves to support their newsgathering activities? I recall seeing a military-oriented portable cellular system advertised in one of the magazines, maybe Defense Electronics. Are such things available for private purchase? (I would think the red tape and paperwork involved in getting official approval for bringing such a system into a foreign country, especially a Communist country, would be monumental and prohibitive.) Maybe all this technology has run on far faster than I realized, and it is not unusual to have a cellular phone in Nairobi or Quito. Any comments on this situation? Regards, Will Martin PS: I have gotten some messages from people asking about getting access to the "Dave-Barry" mailing list, because I mentioned that when forwarding his piece on call waiting. Unfortunately, "reply" has generated some failed mail and I can't get back to those people. So, if you sent me a message and didn't get any answer, it isn't because I didn't try!

AUGUSTA(AP) -- A state plan to permit telecommunications companies to lay fiber optic cable within interstate highway rights-of-way has been approved by the Federal Highway Administration, Gov.

Officials said the plan is designed to ensure motorist safety while promoting the modernization of the state's telecommunications network. McKernan, in a prepared statement, said that "in today's economy, the ability to 'move' information is becoming as important as the ability to transport commodities.

Date: 4 Jun 89 01:24:43 GMT Reply-To: Mike Morris I hear that in a few years, we'll be able to know the number of the calling party before we pick up the phone. How exactly will that work? Will it be a squirt of modem tones between rings? Or will it be when ISDN ("Innovations Subscribers Don't Need") comes into the house, requiring me to junk the 1A2 system inthe basement (and all the stuff I've got wired into it, like 4 amateur radio base stations, intercom to all 9 rooms, plus 4 outside talkback speakers, and much more). Can any body elaborate on what the plans are for the local loop? I'm not asking for anybody to spill any beans on stuff not already announced, just to let us know what to expect in the next few years. Lastly, can anybody explain why the local BOC is charging MONTHLY for a number assignment? Background: Several years ago I had 818-445-6453 as a second line in my parents house. After about a year, I lost my job, and to cut expenses had the number disconnected. Several years later, I inherited my parents house, and the number that we'd had since 1965. When I moved in, I decide to put a 2nd number in the house for the computer and the modem. When I tried to get my old number back, I was told it was available, but it would be an extra charge PER MONTH. Knowing computer systems, I know that assigning a specific phone number is no more work than assigning a random one, but still I'd be willing to pay an extra $10 or so, when placing the order. BUT NOT EVERY MONTH! CAN ANYBODY EXPLAIN? Or is it just seen as another cash cow to be milked? US Snail: Mike Morris UUCP: Morris@Jade.JPL.NASA.gov P.O.

This seems to be the database that AT&T uses in itemizing its long-distance calling charges. The reader is pretty smart, but has problems in cases where vowels are removed from the city name because it would otherwise be too long. Then it just reads the letters in the name. Also, it tries to read out as words the two-letter postal codes for state names.

And not just available to the government -- it really is there for the use of the foreign business community. Beijing was really trying very hard to be a modern city. I agree that it is amazing that the phone service was not shut off, but it's equally amazing that essentially all international long distance service is still working normally. >Just how worldwide IS cellular telephone service implemented? I didn't >think it even was available all over Europe yet. We Americans tend to think we've got the best of everything, but we're often wrong. Cellular phones are much more common in some European countries (Sweden in particular) than here. And in many cases the systems are much more fully developed and quite sophisticated. The NMT-900 system operating in the Nordic countries works automatically in all four countries. Even for incoming calls, with no nonsense with "roamer ports." Germany's C-Netz (which I used during a recent trip) operates almost all over the country, even in some fairly rural areas. No matter where I was in Germany, I could be called from all over the world on the same number. Incoming calls were at no cost to me. The system in the U.K., which uses the same hardware as the U.S. system, but different software in the phones, is likewise a nationwide integrated system. In the 1990s, Europe is supposed to introduce a new pan-Europe system which will work no matter where you are in Europe. Cellular users in the U.S. can hope that our regulators will get their heads out of the sand and allow our systems to connect together by then. (We just got Follow-Me-Roaming here in Boston, and I refuse to use it, because NYNEX Mobile has decided to charge local airtime in addition to the long distance call and roamer airtime. Fortunately, I have a computer at home that can transfer callers to the roamer port.) The following table lists countries with cellular systems. The protocol used in the U.S. is "AMPS." Theoretically, a U.S. cellular user would be able to use his phone in any of those countries. In fact, local regulations often do not permit you to even bring your own phone into many countries.

Access to Mercury is gained over the ordinary BT exchange line by pressing the Mercury button before dialling a phone number.

Back in the "old" days, you could come up with a cutsey number, especially one that spelt something when you used the numbers on the tone pad and get the telco to assign it to you. So if you had a whore-house you could ask to be assigned 438-5243 which spells out GET-LAID. If the number was already assigned, you would have to do a deal with the owner of the number and get them to relinguish it - or to be high tech, call forward it to your old boring number. Well about 4 years ago Pacific Bell - Mike Morris's telco - figured out that they could rent these nifty numbers to people rather than giving them away. So if you request an unassigned number the cash registers clang at Pac-Bell.

Date: 7 Jun 89 18:57:09 MET (Wed) From: "Kim F. Storm" Starting May 16th, all area codes in Denmark were changed from the old 01 to 09 (where the 0 was left out on international calls) to area codes in the range 31 to 99, while the last 6 digits are the same for MOST subscribers. This has effectively expanded the numbers from 7 digit (+ leading 0) to 8 digit. The change was very well prepared, and everything has worked very well from day one. The reason for the change was that the old number scheme ran out of numbers in the Copenhagen area (which were split into two areas a couple of years ago). The old 7 digit numbers (+ 0) will work until January 1st 1990, and so will international calls using the old numbers (a time out is used to distinguish old 7 digit numbers from the new 8 digit numbers). The problem with the approach is that the assignment of new area codes is almost arbitrary in large areas. For example, 01 becomes any of 31, 32, through 39, 02 becomes 42, 43, ... 49, 03 becomes 52, 53, ...., etc. The only way you can know the new number is to lookup the old 7 digit number in a conversion table. The really funny thing about this number change is that except for the numbers in the central of Copenhagen, all area codes will change again sometime within the next 15 years as the centrals are replaced by digital exchanges, i.e. about 50000 numbers will change each year! So be prepared for problems dialing into Denmark for the next 15 years :-) The market has been flooded with programs (mainly for the PCs) which can go through files and replace phone numbers correctly. However, many companies use the phone number as account numbers for their customers, so I can imagine all sorts of problems if these programs are used by the average non-expert PC user. I think this example puts some perspective on the "oh no, now we have to use the 404 area code inside the 404 area" and similar debates. We went through the same excercise one year ago when the tel.co. prepared the transition to 8 digit numbers: We had to learn to use the 0N area code inside all 0N areas! I also think this demonstrates that Danes are very tolerant people. --- Kim F.

Reply-To: langz@asylum.UUCP (Lang Zerner) Organization: The Great Escape, Inc. When I got my basic service installed here in Palo Alto, CA, the guy on the other end asked if I wanted the touch-tone "option". I asked him what the additional cost was, and took it. Then I gave him the old "Did you know..." about how when the phone-using public was paying for the research that led to touch-tone, it was told (correctly) that touch-tone would bring down the cost of running the phone system and (incorrectly) that the savings would trickle down to the consumers. He was surprisingly knowledgeable for a sales rep, and we had a nice conversation about the current state of digital systems implementation and arbitrary restrictions on ISDN services. He also said that "PacBell is lobbying (some regulating body (the PUC?)) to kill the extra charge for touch-tone". PacBell is a business. It wouldn't try to kill the touch-tone charge unless (a) they believe that the cost of supporting pulse dialing will soon exceed the revenue of touch-tone charges, or (b) they have been overcome by an irrational urge to charge for a service proportionally to its cost. If PacBell is anything like other BOCs I've done business with, I find (b) to be exceedingly unlikely. Anyone have any evidence suggesting (a)? Any other reasons PacBell would be lobbying for such a move? Any evidence that the sales rep was mistaken (i.e. that PacBell is making no such lobbying effort)? I have always felt that tone "service" charges were one of the most irrational BOC charges. There is no extra cost to the BOC, and in some cases it results in *lower* operating costs. I am very interested to learn if there is any truth to the rumor that the charge may be removed. -- Be seeing you... --Lang Zerner ARPA:langz@athena.mit.edu MX:langz@asylum.sf.ca.us UUCP:bionet!asylum!langz "...and every morning we had to go and LICK the road clean with our TONGUES!" ------------------------------ From: Scot E Wilcoxon Subject: Guerilla FAX Date: 7 Jun 89 13:10:50 GMT Reply-To: Scot E Wilcoxon Organization: Data Progress, Minneapolis, MN A group of Chinese students at the University of Minnesota are gathering news of the Chinese upheaval, translating them into Chinese ideographs, and FAXing the news into China.

Please rest assured that sci.commtech will include issues other than those currently discussed in comp.dcom.telecom. As a comp.dcom.telecom reader myself, I *know* that this is the case. I proposed sci.commtech partially inspired by comp.dcom.telecom. I am not a telephony or computer telecommunications person. My background is in broadcasting. Sci.commtech is intended for those of us who do not share your impressive expertise in the technical details of telecommunciations and uses of telephony. Sci.commtech, if you followed the discussion, is intended as a more "soft" newsgroup. It is also intended to discuss new "media" technologies which may, of course, include those related to telephony. As I read the latest postings in comp.dcom.telecom today, I did not see one which I felt was appropriate for sci.commtech as proposed. Please, if you have questions about sci.commtech...email and I will reply. I (and others) are *very* enthused about sci.commtech, and it would be more than a shame if we cannot establish this new newsgroup due to mis- understandings about its intent. Thanks very much.

The limiting factor involved when adding devices to a telephone line is simply the number of ringers (or more precisely, ringer equivalence) on the line. When a device is "on hook", it presents no load to the line other than its ringer. If the device has no ringer (or its ringer equivalence is "0.0") it is totally invisible unless you take it off hook. If memory serves, I believe the maximum REN (Ringer Equivalence Number) allowed on a 1/1A ESS is 8. Higher than this, the CO will withhold ring current and you will never know anyone is calling you. This has actually happened to me and it was very embarassing when I turned in the trouble call. They told me I had too much stuff on the line. Add up all the RENs on your devices on any one line and if it's less than 8, you are probably OK. -- John Higdon | P. O.

What you must do is add up the ringer equivalence numbers of the various devices you wish to connect. The maximum total REN for a given subscriber line depends upon the serving central office, and on the length of the loop.

I bought Mercury service without one of the expensive feature phones they sell. The person I spoke with didn't know the code, but called me back once he found it. By the way, the access code can differ from one STD area to the next. Also, I found that, even where the access code was the same I couldn't use my secret code outside of the STD of the home phone for which I bought the service. I called Mercury about that and the service person looked into it for me. Apparently, they are not authorized to provide "traveling service codes". Service is ostensibly tied to your phone, really to your STD. They were working on getting equal access-type service when I left In February. By the way, as I understand it, they aren't the only company *allowed* to provide an alternative to BT, but the only company that *does* provide it. Other companies are working on it.

Hit this, and if you're in an area where the service is available, you'll get a high pitched noise like a modem carrier. To use the service, you have to enter a ten digit identification code, and then the number that you want to be connected to, always including the STD code. You can connect to almost every number via Mercury that you can via British Telecom. Notes: 1) All the signals you send after dialling the 131 must be using DTMF signalling. 2) Your id code is validated for a particular number. In practice, it will also work from other phones in the same area, though this is not guaranteed, and I suspect the areas will get smaller as the network expands. At the moment, it seems that I can use my code anywhere in the 01 (London) area. 3) Most modern BT call boxes (including some card phones) will switch to DTMF after you have dialled the initial 131. This means I don't have to give BT much money at all anymore. 4) Making local calls via Mercury is about 3 times the price of making them _from_your_own_phone via BT. Mercury is after all designed for long distance calling. However, if you're using a call box, BT is about 6 times the usual price for local, cheap rate calls. 5) I have had very few problems with Mercury. I have had lots of problems with BT, and even phoning the chairman's office doesn't help much these days. (Dial 01-356 5000 and ask for the chairman's office) 6) Occassionally I get bad lines from Mercury. As far as I can tell, this is caused by BT. The phone in my office always gives very good connections to Mercury, but the other line, off an older BT switch tends to be a bit faint. Hope this is of some help. A slightly related topic; some of the phones now on sale in this country have "TouchTone" which it is claimed is a trademark of British Telecom. I have no connection with either of the phone companies, except as a satisfied customer of Mercury, and an extremely dissatisfied customer of British Telecom.

The answer is (c), it is part of a package of general deregulation that Pac*Bell is trying to get past the PUC and getting flack on all sides for doing so. Pac*Bell would like to be able to set its pricing in the competitive business market without the giant hand of the PUC getting in the way. As part of the inducement, they have promised a freeze in residential rates through 1991 (or 92, I can't remember and someone threw out the newspaper), elimination of the touch-tone charge and other goodies. The opposition, in the persona of other telecom services and consumer groups are vehemantly opposed. The other service providers are afraid that Pac*Bell will have great unfair advantage in a non-regulated environment with its control of the local wire plant. Consumer groups feel that residential service should come down, not be frozen at the current level. IMHO, the business may have a point, but it's hard to get behind the consumer groups. They are steadfastly against the plant upgrading that Pac*Bell is proposing, saying that it is too costly and that rate payers shouldn't be stuck with it. Most of the consumer advocates that I have spoken with, however, seem to feel that adequate telephone service consists of a black rotary-dial wall phone in the kitchen and the fact that there is a hell of a lot of electro-mechanical equipment that needs replacing is of no concern to them. I haven't made up my mind about their proposal, yet. On the one hand, it seems logical and reasonable. And I certainly wouldn't mind some plant upgrading. On the other, I tend to distrust any proposal by the utility because I know whose interests they are really trying to serve. -- John Higdon | P. O.

For a few days now at least, calls from Chicago to 415-976-anything have been getting intercepted at a switch in Chicago and rejected. I was unable to find a single routing which would work. 10288 (1 plus on my lines) immediatly cuts in after 1-415-976 without waiting for the final four digits -- "Your call cannot be completed as dialed. Please check the number and dial again, or ask the operator for assistance. Three One Two, One Tee" However the operator was also unable to complete the call, or explain why not. 10222 waited for the complete eleven digits, then said, "We're sorry. MCI does not complete calls to 976 at this time." (click) 10333 accepted all eleven digits, then intercepted saying, "Forty Four! Five Oh Three! Your call cannot be completed as entered. Please call Customer Service for assistance." (and it kept repeating) 10444 accepted all eleven digits, paused, then gave a spurt of dial tone from somewhere for a couple seconds, followed by two rings, and a report, (one voice saying) "Forty seven dash three" followed by a different voice saying "We're sorry, but your call cannot be completed. Please check the number and redial, or call Customer Service." 10888 accepted all eleven digits, then *Illinois Bell* responded, "The long distance company you have selected cannot complete your call at this time. Please try your call again later." Growing frustrated at my inability to call a service which I enjoy using sometimes, I tried a different tactic. The firm which employs me has a WATS extender which I am authorized to use when working from home. A local Chicago seven digit number connects me. Calling into the diverter and entering my password, I then dialed the three digits for the tie-line to our branch in New York. Getting their dial tone, I dialed their access code for WATS, and again tried to dial 415-976-my thing. This time, a *very funky* recording from somewhere -- I know not where -- cut in after the 415-976 part, without waiting for the final four digits, and told me, "again. The number you have dialed is not in service. Please check the number and dial" (pause) (repeat, beginning with 'again') Attempting to make the call from the nine-level trunks off the New York PBX got me a New York Telephone intercept similar to the one in Chicago. Although we have an office in Canoga Park, CA, I know for a fact that all 976 numbers are blocked at the PBX level there, just as we have all 1-900 and 976 numbers in area 312 blocked in our PBX here in Chicago. But I figured I would try it anyway. As expected, calling through the nine level local trunks out of Canoga Park blocked all 213-976 and 415-976 numbers. Forcing the call through 9-10288 + 1-415-976 out of Canoga Park got me through. Finally! As to be expected, the transmission was lousy, and I don't intend to bother dialing all those numbers in the future just to make the call. So I guess its goodbye 415-976 from outside the State of California!

PacBell's California Online -- which will be available to anybody with a personal computer, telephone and calling card -- will be among the first in the nation to use a graphic-based system that simplifies procedures so only a rudimentary familiarity with computers is needed. "It's going to offer our customers a supplement to their current leisure activities ... and among other things we've seen (in trials) a lot of people who got away from the TV," said Roger P. Conrad, director of Videotex Gateway Services. "We feel this is a more productive way for people to spend their lives and we think a lot of users are going to agree," he added. Users will pay "info-entrepreneurs" fees based on the time they use various services and will be billed on their monthly telephone statements. Unlike some online information services, users do not have to subscribe ahead of time. Conrad said the types of services are limited only by vendors' imaginations.

In fact, I've discontinued having any service at all at home, and have started using email more and more to carry on important communications, since, unreliable though it is, it works more reliably than our new super spiffy digital AT&T PBX with LEDs and whatnot. Our old electromechanical system worked vastly better. Unfortunately, we reached its limits, and it is no longer supported, and cannot be expanded. So we get a lot more exercise now, which is good; it is easier and faster to walk down the hall, or indeed across campus, than to try to get out using the spiffy new digital phones (with LEDs). -Bennett bet@orion.mc.duke.edu ------------------------------ From: Ed_Han Subject: Is it possible to trace international calls?

Date: 11 Jun 89 03:38:19 GMT Organization: MIT Media Lab, Cambridge, MA My understanding is that AT&T registered "touchtone" as a trademark when they invented DTMF, but surrendered it at divestiture (midnight 01 Jan 84). Most of the Bell System intellectual property rights were divided up between AT&T, the RBOCs, and Bellcore, but "touchtone" was instead released to the public domain. The reason was that AT&T wanted to keep "touchtone" to describe the DTMF capablities of its common carrier operations, CO switches, computers, and CPE, while RBOCs wanted to be able to sell "touchtone"-compatible dial-tone. Because of this decision, anyone can now sell "touchtone" products or services. Someone said BT claims "touchtone" as trademark in the UK, which is probably OK under international intellectual property law. The story is different for the Bell System symbol. (There's a good article in a 1971 issue of Telephony magazine on the design of the Bell System symbol and the color scheme of Bell System vehicles.) The Bell System symbol was given to the RBOCs and Bellcore. AT&T had to come up with its new non-concentric circle-within-a-circle-all-made-of-horizontal-lines symbol.

Hmmm. I wonder if PacBell will do what SW Bell did when they signed a contract with some company for introducing a teletext service using modified MiniTel equipment. It's interesting that in both Texas and Oklahoma, they subsequently re-classified all "free" public access BBS's as "businesses" (though it is being fought in the PUC of both states). And a telephone installer here noted that South Central Bell has ordered them to report any computer equipment they see while installing new lines... signs of future BBS pogroms?

The fact that local service, from the RBOCs as well as independent telcos, is quickly stripping away any possible cost benefits from LD competition, has been duly noted.

In two messages in the Digest today, Dean Riddlebarg and Gregg R. Siegfried discuss what they expect from [Telecom Digest], and what it has come to represent to them when they receive each issue. They both speak of the Digest as a *technical* publication, and while that was true in the beginning years, and remains true to some extent today, the Digest is, to me, more than just a dry recitation of technical data relating to telephony. When Jon Solomon founded the Digest, in August, 1981, it was an off-shoot of HUMAN NETS, and intended as a place where technical discussions not suitable for the entire HUMAN NETS audience could be conducted. And the Digest served its purpose very well, as anyone reading through the old issues in the archives will attest. A few of the original participants from those days are still on the mailing list today, as we near the end of eight years of e-publishing. But 1981 was a different time: While some folks had limited experience with alternate long distance carriers, and some were served by ESS offices, most Digest readers were being served by *THE* TELEPHONE COMPANY via those nice old reliable crossbar offices. New technology meant having touch tone and the ability to dial international calls direct for most users. The divestiture of *THE* TELEPHONE COMPANY a few years ago brought many changes to the scene, including politics and judge-bashing, to name just two. The technology began improving expotentially. Everyone began doing their own thing. Ma Bell, in her old age, was euthanized, or 'put to sleep' although it was not much of a mercy-killing to hear some people tell it. For better or worse, the telephone industry in America primarily, but around the world as well began changing dramatically. While [Telecom Digest]/comp.dcom.telecom still functions as a place on the net for technical discussions relating to telephony, the discussions can't stop there. For many, many decy, some commentary is presented in better taste than others. If it is too far afield, I decline the message; and you should see -- just *see* -- some of the stuff I return to senders almost daily. Digest readership and participation has grown substantially since Jon Solomon was operating it. This is not a negative comment about jsol at all; the increased participation and message traffic would have come whether he was here or not. It had to, with the increasing awareness people have about their phone service, and the growing myriad of options and features now available. I think the best here in the Digest is yet to come, so please stick around, won't you, and share it with me.

The following is an excerpt from a letter from Pacific Bell to 976 Information Providers dated May 4, 1989: "On February 22, 1989, Pacific Bell requested that the local telephone companies and the IECs block the California 976 prefix outside the state. This action was taken to help eliminate unbillable interstate calls from reaching California programs. Apparently Pacific Bell's 976 serving central offices are unable to reject 976 calls carried by IECs (long distance carriers) from outside of California (and still accept calls originated within California.)

Pacific Bell 900 ICS is an intra-LATA service only (i.e. to cover all of California would require telephone lines (and equipment) in all 10 California LATAs, furthermore calls from outside of California would not be permitted). If I were thinking about becoming a Videotex Information Provider I would seriously consider the 900 services available through the long distance companies (AT&T, MCI, Sprint, Telesphere, et. al.). The per minute charges for 900 via IEC (long distance company) are greater but the simplicity of ONE set of phone lines in ONE location outweigh the increased per minute costs. If you were interested in Pacific Bell's Videotex services I would call the Mr. Conrad mentioned in the AP story you lifted -- a starting point would be to call 811-4976 (CA only, otherwise (213) 975-4976). -Richard Edell (edell@garnet.berkeley.edu) (UCB EECS student and 976 Information Provider) The above opinions are my own (but not exclusively mine). ------------------------------ Subject: hunt groups vs. starline Date: Mon, 12 Jun 89 07:19:23 -0400 From: chipcom.chipcom.com!eli@eecs.nwu.edu Fred Blonder asked about hunt groups and the grief his local CO is giving him since he wants to hunt between lines billed to different people...

Organization: Ellemtel Utvecklings AB, Stockholm, Sweden >Just how worldwide IS cellular telephone service implemented? I didn't >think it even was available all over Europe yet. Just for your info, and trying not to sound too vitriolic, I'd like to point out that the cellular phone system you use is largely based upon the Scaninavian one. The Scandinavian NMT-450 (Nordic Mobile Telephony) network covers all of Scandinavia and Swedish telecom-manufacturer Ericsson is in fact world-leading in sales of exchanges for cellular systems. Ericsson actually had something like 50% of the American market when I last heard any sales figures (a couple of years ago so this may have changed) and this should be weighted against the fact that so far, North America has been one of the SMALLER markets as cellular goes. A couple of years ago, there were more cellular phones in Sweden alone than in all of North America! This may seem amazing, but for once we've been favoured by our state-monopoly telecom administrations. The cellular networks have been integrated with the national radio networks so that the transmitters didn't need their own housing etc. This meant a quick build-up phase. Also, the build-up wasn't dependant on sales. A decision was made to cover all the area, and then they simply did it. What surprised everybody was the very rapid success of the system. Up until this time, mobile telephony was considered a luxury commodity. Suddenly every plumber and workman with a small enterprise of his own moved his office to his car with no need even for a receptionist. Swedish tax-laws make such expenses tax-deductible which meant that the cost for the phone, while high compared to a regular land-line subscription, was negligible in running a business. As a matter of fact, traffic outgrew the NMT-450 system years ago and the second generation, NMT-900 was introduced. This runs on 900 MHz as opposed to 450 and thus covers less area per transmitter. The smaller cell size effectively yields higher capacity but at the cost of more transmitters. Thus, the NMT-900 system only covers the major urban regions and main national roads. However, the phones need less power and shorter antennas, so they have become very popular where they can be used. Customers have a choice of 450 or 900 MHz when opening a subscription, with a warning that 450-traffic may be congested in urban areas and 900 may be unavailable in the country. Other countries have followed, but so far Scandinavia has been the only major multi-national cellular system. Different European countries have jumped on the bandwagon at different times and thus have opted for either the 450 or the 900 systems. Most of them, though, buying the stations from Ericsson. Motorola tried to move in on this huge market and have in fact managed to grab a small slice (20%, I think) here in Sweden, but NMT dominates completely. Of course, what the user sees is only the phone, not the exchange, and Ericsson have never been able to compete with cheap Far-East mass-produced subscriber equipment. Nor has this ever been their intent. They specialize in switching equipment (quite successfully so). At the present, work is going on throughout Europe to standardize a third generation system with digital transmission and a true pan-european standard. This means that a subscriber will be able to travel anywhere from Lisboa to Ankara to North Cape and still use his own car phone with the same number. All routing and charging will be fully automated. As far as I can see, the split of Ma Bell in the U.S. messed up the situation for you. IF Bell had been able to keep their hold on the market, and IF they had branched out into cellular early enough, they MIGHT have been able to offer you a continent-wide system without the routing hassles you seem to be suffering now. I'm not generally a big fan of state monopolies, but it's strange that Sweden should be among the cheapest countries for phone users consistently year after year with the high costs of net maintenance we have (sparse population/large area) for both cellular and regular phones. They must be doing something fairly well. BTW: As you can see from my return-path, I work at a subsidiary of Ericsson. I am not, however, in any way involved in their marketing nor do I have anything to do with the NMT-systems professionally. What I've said here is just my own personal compilation of general knowledge about this market.

Thanks for the info. I was NOT trying to imply that the American cellular situation was superior to everywhere else (after all, what I mostly read about it are complaints! :-); what I was getting at when I used the "all over Europe" phrase was that I was surprised that this technology was available in China when I was under the impression that it had not been implemented in *every* European country yet. I've seen several responses citing Scandinavia as a place where it is completely (or nearly so) installed. But what about places like Portugal, Yugoslavia, etc.? That's what I meant -- I thought that cellular did not yet completely cover Europe, and it appears from the chart Mr. Covert posted that this is true. I realize cellular is not available "all over" the US yet, and I suppose never will be, given the presence of large areas of sparsely-populated countryside, like in Nevada and similar places. I suppose I should not have thought it at all remarkable that a major city like Beijing would have installed cellular in that metropolitan area, but it came as a bit of a surprise, since I was not aware of the international extent of cellular, to hear that it was available in a Communist country usually classified as "third world".

You can buy "ringing switches" with modular cords from places like Radio Shack. These are nothing more than a rectifier and a switch which lets you bypass the rectifier (ringing on) or activate it (ringing off). If you want to tinker with this yourself, be sure to select a rectifier which won't fry on your first call, remember that ringing is something like 90V AC.

If I recall my Part 68 correctly, the rule on Ringer Equivalence Numbers is that all devices must not have a combined REN greater than 5. Not 6 or 8 as previously reported. This is the standard that all CO switches are built to. Some may actually support more, but the telco is obligated normally to allow up to 5 REN total, and that's what they're now built for. REN of 1 comes from the traditional electromechanical ringer, but not even all of them are equal to 1. I have a Northern Telecom deskset (1986 Link model) with a real bell (not a fire alarm chirper) with an REN of 0.8A, which is typical of modern equipment. Some modems and answering machines, which don't need to really ring, have RENs in the 0.1 range. A friend had trouble in her apartment, with phones not being audible, and it turned out to be an REN violation. The answering machine was something like 1.2, and there were four other phones... Unplugging any one device made them all ring, but with the REN overload, the ring voltage fell too low for them all to ring. SOme devices rang, but were anemic, while others didn't ring at all. Yes, it's a violation of telco rules to overload your line.

Why two symbols for unspecified > digits, here? Why N1X rather than N1N or X1X? And why NXX rather than > any other combination on Ns and Xes? Does this mean anything, or is it > just traditional? In telco shorthand, N = any digit from 2 through 9; X = any digit from 0 through 9. Before the advent of common control switches (where a single controller, either electronic or electromechanical, reads the whole number and then sets up a path through the switch fabric), the first three digits of a phone number were used to determine what sort of treatment to give a call. Special treatment was recognized by a 0 or 1 for the first digit. An "N" -- 2 through 9 -- in the first digit therefore meant "handle normally". A long-distance (out of area code) call was recognized by a 0 or 1 in the second digit, so an "N" in the second digit meant "inside this area code -- expect only 5 more digits". I don't know why 0/1 were chosen as the special numbers; it may have been tradition or it may have been some operations research whiz at Bell Labs doing some T&M studies... Anyway, the result of this is that, to date, office codes are generally of the pattern NNX and area codes (or Numbering Plan Area codes, NPA codes for short) are of the pattern N0/1X. If you've been following the discussion here lately, this all becomes moot over the next five or six years as the lack of codes leads to interchangeable CO/NPA codes. Both CO codes and NPA codes will be of the format NXX. -- David G Lewis ...!bellcore!nvuxr!deej "If this is paradise, I wish I had a lawnmower." [Moderator's Note: I think 0/1 were chosen probably because at the time this first came up for consideration, telephone companies were just beginning to move away from Pennypacker, Pennsylvania, Sheldrake and Buckingham style exchange names into ANC (All number calling). And which two numbers on the rotary dial did NOT have letters associated? Zero and one. I have seen exactly *one* very old, circa 1920's instrument which had the letter 'Z' on the zero-operator hole. '1' was always held out as a special sort of digit.

I have found that calling the East Coast from the West Coast almost universially gives you a clear digital circuit when the call is placed via SPRINT, and almost universally gives you a cruddy circuit when placed via AT&T. I believe this has to do with capacity, since John Covert almost always gets great circuits when he calls me via AT&T in the other direction. At the moment, the improvement in quality is good enough reason for me to stick with SPRINT for our company lines, but as soon as AT&T expands their capacity I am willing to reconsider. I think it is perfectly reasonable for someone to express their opinion on any LD carrier on this forum, and I wish the people who represent such companies and read this list would be a little less sensitive and patriotic to their company whenever anything negative comes up.

"Oh no! You're not in town, are you?" I don't think people have to "refrain from this in the future". Instead, it would be useful if people posted the cities between which they notice excellent (or bad) service with different carriers. I often try different carriers when I call friends in NYC and the West Coast. Sprint always has the best connections to my (admittedly damaged) ears. ATT always seems to have more static and less overall volume. MCI and ITT are so poor that I usually redial the call through US Sprint. Ellison's friends' reactions fit well with what I learned in my years working in the voice messaging industry. Perceived quality is largely dependent on VOLUME, VOLUME, VOLUME!!! US Sprint is the loudest long distance carrier (double entendre?). A recent (Byte?) magazine article rated long distance carriers for modem connections. ATT won, but Sprint ran a close second, with Sprint being given the highest marks for loudness. -- Steve Elias -- eli@spdcc.com, eli@chipcom.com [mail to chipcom.chipcom.com bounces!] -- voice mail: 617 859 1389 -- work phone: 617 890 6844 ------------------------------ From: cblph!grs@att.att.com Date: Mon, 12 Jun 89 16:45 EDT Subject: LD carrier span comparisons Steve Elias suggests that we discuss perceived quality on a carrier by carrier basis for calls between various cities.

Posting shallow references to his corporation's widely publicized media advertising campaign was what I thought to be a bit out of line with the guidelines for technical discussion.

If I want to read advertising campaigns, I'll pick up a magazine. Indeed, accounts such as "Last Monday at about 22:30, I attempted a call between Philly and Omaha with LD company X, and found it to be unable to maintain 2400 bps carrier. I then tried LD company Y.

Excuse me, but time zones and daylight savings time have very little to do with country codes. I can see two reasons for separate country codes, one more valid than the other: (a) from certain nationalistic perspectives it rankles that Canada is the only major country which does not have its own country code and has to coordinate its internal telecommunications affairs with entities in the U.S. (I don't hold that view, but then I am neither Canadian nor very nationalistically inclined); and (b) Giving Canada a separate country code frees up a few area codes for use in the U.S., and **lots of area codes** for use in Canada (this one I consider the more valid reason).

Southern Bell Telephone Company officials have acknowledged that a hackerphreak invaded a central office over the weekend, using a computer and modem, and reprogrammed their computer in such a way that calls intended for the Probation Office were instead routed to a New York-based phone sex line. "People are calling the Department of Corrections and getting some kind of sex palace," said Thomas Slingluff, a spokesman for the Palm Beach County Probation Department. Southern Bell officials said it was the first time their switching equipment had been maliciously reprogrammed by an outside computer intruder. Southern Bell provides the local phone service for Florida, Georgia, North Carolina and South Carolina. "We are very alarmed," said Southern Bell spokesman Buck Passmore. He said the intrusion "...obviously required someone with considerable computer skills and knowledge of the telephone system." He pointed out the implications of such a computer breach are enormous. In addition to merely intercepting the communications of others, other serious problems include finding out unlisted phone numbers, and tampering with billing records and/or the billing software. Passmore admitted hackerphreaks have invaded Southern Bell 'lots of times in the past', but he denied they had ever before been successful in altering the the software in the switch itself. It is believed that the intrusive calls were made on Sunday, June 11 via AT&T long distance lines to Delray Beach, and security representatives from Southern Bell and AT&T are working jointly to trace the breach. But Passmore admitted, "We really have no idea at this time who it was or how it was done."

I'd like to point out that while Merlin offers great features (we have one at work), it is probably the most expensive system you can buy. (The cheapest Merlin phone is over $200, a "reasonable" one, the kind most employees would want (BIS-22) is $395). For larger businesses this is probably OK, but I am really surprised that AT&T hasn't entered the "simple PBX" market. Panasonic has a 6 CO line, 16 extension system for about $700, it requires only one "wizard's console" and supports *standard telephones* (my rotary phones from the 30's and 40's work just fine). Again, you cannot fault AT&T for quality, but I really wonder about their pricing (look at what they charge for a FAX machine these days!!).

Some of you may have seen some of the newsgroup messages about this [i.e. a reader asked whether or not the newsgroup/digest could deal with technical *and* subjective matter, I noted that most of the talk leans towards the technical, some other corporate flame wars flared up, etc. etc.]. Well, whatever our views on the theme of the messages, we did decide that it might be fun to throw some subjective topics into the fray. So....... I would argue that, since divestiture, the general public has been increasingly alienated by the telecom situation in this country. Many analyses of the telecom market suggest that, while LD competition has brought some degree of cost savings and service flexibility to the average resident, this has been offset and perhaps overridden by cost increases on the local side. It would seem that only large businesses have been able to gain true functional benefits while reducing all average costs for service. The debate questions, then, become: [1] Do readers on the net agree with this assessment? If so, why? If not, why? [2] Is this assessment generally true today, but likely to be nullified as more time passes? Has five years simply been too short a time to see all of the benefits? [3] Could we have done it better and/or differently right from the start? [4] Could we modify the process now in order to once again favor the average resident? Would we want to? I trust that this topic is somewhat relevant, and further that it is structured so flame-oriented opinions on various companies can be avoided. Have fun! I look forward to seeing responses......

Admittedly, the boundary between PBX and EKTS is fading, but generally, in a PBX, routine calls are placed to other extensions, and outside calls are dialed with an access code (like 9). PBX users generally don't have access to a specific line, and can't tell when a line is in use. PBXs are geared for lots of single-line phones. An EKTS generally has multi-line phones, and users compete for the outgoing lines. Users either shout at each other (because the office is small) or use one of several intercom lines. * I like my Merlin system. I compared it with many others, and found it unbeatable, except for price. I was interested in top-quality performance, lots of features, flexibility, expansion. (8 phones at home is NOT enough.) * I agree that prices are a bit high. The cheapest phone (5 programmable buttons, plus a number of feature buttons) is around $200, but is widely available used, and there are discounters offering 25% off Merlin systems and components. * Merlin phones can be used on larger systems, like AT&T System 75 and System 85 PBXs. * Merlin will support single-line phones, but it costs around $300 to support these. (Of course, you could have multiple phones on each adapter.) With this arrangement, you have access to all the features that a multibutton phone has. * After writing to AT&T to complain about prices, marketing strategy, etc, I was reminded that they do have two lower priced products: Spirit, a system with 80% of Merlin's features, but only two styles of phone. Pricing is about 20 - 30% less than comparable Merlin systems. The other one escapes me, but is a simple 2-line system that works over standard inside wiring. (would work well at home.) I had suggested to AT&T that they market Merlin for home use, but they countered that most people don't have 4 pair wires running from each room to a central location. * I'll repeat a request from the past: Does anyone know the protocol Merlin phones use to transmit button-press information back to the central unit? =John Shelton= ------------------------------ From: Chip Rosenthal Subject: Re: Number of devices on 1 line?

It got connected wrong, so I hung up after a few minutes of trying to find the person I wanted and finding I had a wrong number. I called their operator and they told me to call customer service, and they would redial the call for me. Again, I got the same wrong number. I called customer service, listened to their tape of advertisements for about ten to fifteen minutes while 'all reps were busy' and then got a rep who would credit my account, and told me I had a 0 in the phone number that shouldnt be there, and to dial it again. By the way, it would take about 37 days for the credit to make it to my bill. (They cannot cancel a billing, just issue a credit, still...). Total time on hold and working with the rep: about 20 minutes. Ok, I redialed the call and it went through fine. Ok, I wanted to see how AT&T would handle this problem, in the pre divestiture days, I would have called 0 and the Operator would have given me an immediate cancelling of the call. Now: First I called the 800 number in the phone book for AT&T Business Long distance, after all, I was calling from a business number. I got a voice intercept on the first ring, press 1 if calling about residence service and 2 if calling about business service. Neat, I call a business only number and I hit a redirect. Ok, I hit 2 and I get a ring and an answer. I ask my question, and totally flabergast the person on the line. They wanted to give me a credit, not just ask about one. I asked how to do it, they replied: I don't know, you have to call xxxx (a different 800 #), but its only answered from 8:30 to 5:00. I hung up and then tried the 800 number from my phone book for the residence users. I got a live person immediately, asked the question and was told to call them and they can issue a credit, or immediately, dial 00 (102880 if not primary) and the operator can still intercept it, sometimes. Total time to get the info from AT&T about 5 minutes. My overall feeling, I liked it better before, when all I did was call 0 and it worked, however, although AT&T answers faster, their people are often no better trained than the others (I have run into this AT&T problem before). US Sprint just needs better billing controls, as they have needed for several years, and more reps to answer the phones. (Perhaps I should start billing them for my time on hold...... :-)). ===================================================================== Sydney S.

I think that he is referring to a System 2000 which sells at the local AT&T phone center for $349.95 for a master unit (which one is required) and $219.95 for each extension phone. You can only have a maximum of 2 lines, but I don't know what the maximum number of stations is. I would love to buy a Merlin system for my house, but I can't afford it. (No employee discounts on Merlins :-( ) I guess that I'll have to settle for AT&T 412's. > * I'll repeat a request from the past: Does anyone know the protocol > Merlin phones use to transmit button-press information back to the > central unit? Merlin phones (the digital phones, anyway) use a proprietary protocol called DCP (Digital Communications Protocol). I'm sure (although I have no first-hand knowledge) that the button-press information is passed via DCP. Because DCP is proprietary, you won't find the internals discussed anywhere. Sorry. Kevin L.

No, the multi-button sets which work with Merlin are analog sets with a digital signaling system for sending button stimuli, and receiving lamp updates. The similar-looking multi-button sets sold with System 75 and 85 are digital sets that encode the voice as well as the signaling information into an ISDN-like bit-stream. The Merlin sets do, however, work with System 25 -- a true PBX with some key-system features.

I believe that the restructuring of rates has been a good thing. The long distance telephone business today is competitive and in almost every way superior to the conditions of 5 years ago. At the same time, the technolgy of the network has been brought up to date; the last few crossbar exchanges are being replaced by new all-digital exchanges as we discuss this. On the other hand, the Reagan era deregulation has created a bad situation in the local service area, not unlike the cable TV business: A monopoly provider has been allowed to raise rates and restructure rates with inadequate supervision. At the outset, pessimists claimed that without the motherly guidance of AT&T, the nation's telephone network would fall apart as ultra-short-term profit hunting discouraged capital investment. This has not happened at all. The breakup has largely achieved the goals that drove it. The ripple effects of changes has been such that it would have been impossible to predict the consequences of minor changes to the plan at the outset. Brought up in "socialist" Europe, I believe that all regulation of the business market should favor "the little guy", i.e. residential customers as well as family businesses. The IBMs of this world can look after them selves quite well. I would like to see more regulation of the local telephone service, to include the following: (1) More readable phone bills. All mandatory charges, taxes etc included in the basic monthly price of service, and all optional components identified on separate line items. (2) Elimination of the "federally mandated LD access charges". Since this charge goes straight to the local service provider as part of the general revenue stream, there is no need to list it separately, nor to mandate a particular amount. This is sheer obfuscation. (3) Equitable charges for all customers. Includes elimination of CENTREX service. If your subscription includes 20 instruments, each with its own wire pair into a switch at CO premises, this is really 20 lines. The pricing of Centrex service to pretend that this is a virtual PBX is sheer obfuscation. (4) Least call call routing. If you do not specifically request a specific long distance carrier, the local operating company should route the call on the carrier with the lowest list price for the given origin and destination. With stored program control exchanges, this would be fairly simple to implement, and would spawn a new level of competition between the long distance companies. -- Lars Poulsen (800) 222-7308 or (805) 963-9431 ext 358 ACC Customer Service Affiliation stated for identification only My employer probably would not agree if he knew what I said !! ------------------------------ Date: Thu, 15 Jun 89 8:40:51 CDT From: Will Martin Subject: Re: Divestiture, Business and the General Public >[1] Do readers on the net agree with this assessment?

Many of the people on this list may respond and say "not so", because they have personally benefitted. Often this is because they make many long-distance calls. I want to point out that this is NOT "ordinary" -- in fact, it is quite the exception. I define the "ordinary" customer as people with POTS, no fancy special services, probably not even touchtone, who have had plain flat-rate local service for many years, and who have seen their bills escalate far more than inflation would justify, because of asinine things like the "access charge" and the forcing of measured service in many areas. The only benefit that has come to these people has been the elimination of the telco restrictions on hooking up your own phone equipment, and this has largely been negated by the idiotic changes in the repair service situation. It could have been achieved by a simple mandate that the local telco couldn't bitch at you for hooking up extra telephones, answering machines, etc., unless you actually caused demonstrable harm to the network. Nothing else needed to change! >[2] Is this assessment generally true today, but likely to be nullified >as more time passes? Has five years simply been too short a time to >see all of the benefits? No. Things always get worse. This is a general principle of life, and is no different in this aspect than any other. Technology may improve, but other things always come along to make the end total result worse. >[3] Could we have done it better and/or differently right from the start? Certainly. We should have left the existing network as-is. Allow competing LD companies to fight with AT&T but under strict regulation. AT&T could have competed on price BY REDUCING EXPENSES, keeping the existing "Bell System" intact. For example, Southestern Bell here in St. Louis spent millions of dollars on new office buildings with fancy furnishings, plush executive offices, and lots of perks. They could have reduced expenses by having offices just like the one I work in myself, with plain grey-metal institutional furniture and minimal fanciness. No money spent on political and charitable contricutions, and no inflated executive salaries. (No reason why anyone should be paid more than the government GS schedule, in any industry anywhere.:-) >[4] Could we modify the process now in order to once again favor the >average resident? Would we want to? Yes. We can roll back things to pre-divestiture days. Sure it won't be easy. It will be simpler if we first kill all the lawyers... The whole damn thing started out with people making too many LD calls and complaining about how much they cost. The point is that it is just flat WRONG to make most LD calls that are made (and, for that matter, most local calls). WRITE LETTERS! LEAVE THE DAMN TELEPHONE ON THE HOOK! Grump! Will Martin ------------------------------ Date: Thu, 15 Jun 89 11:59:22 EDT From: dibble@cs.rochester.edu Subject: PBX or EKTS I've been reading the messages about PBX/Key systems with interest. I called AT&T to get information about their systems, and got a good dose of discouragement. They only sound usable if you have no existing equipment like modems, fax machines, and telephones. Was the sales person right? The only way to put a modem/fax/phone on an AT&T key system is through a dedicated port that passes straight through to an outside line? Are there systems comparable with AT&T's but able to support my existing stuff? Why did AT&T fail to support the conventional telephone interface? What do these systems do in case of a power failure or a hardware/software failure? Will any of them let me backspace in a number I'm dialing?
