D. Parker <mike@LOGICON.ARPA> To: Telecom%BBNCCA@Nosc Cc: mike@logicon Subject: Modem calls using NON-ATT carriers I recently attempted to utilize some of the other long distance carriers to call other modems. However, I have run into some problems and it seems to be independent of the baud rate (both 300 and 1200). Here are some characteristics of the problem: 1. Call other modem number. 2. The remote modem answers and my modem gives a CONNECT indication. 3. Barely seconds into the call the modem gives me the NO CARRIER indication and the call is terminated. There are no 'noise' brackets (i.e. {{ at 1200 baud). I do not have this problem using the ATT. What kind of problem am I seeing here? Is this simply a weak signal over the connection?

If so, how does the equipment work? Thanks, --Bi// ------------------------------ From: dual!qantel!stv@Berkeley (Steve Vance@ex2499) Subject: more about Premiere Date: 15 Apr 85 18:52:29 GMT I have the Bell pamphlet, "10 ways Premiere makes your life a lot easier", which doesn't tell me everything I would want to know about it, by any means. Apparently, Premiere is something you can get when you have two or more phone lines going to your house, or when some family member lives near enough to you to be serviced by the same ESS office. The brochure is only 10 pages, with one sentence per page, with a cutsie picture depicting what the sentence is saying. What follows, in fact, is the full text of the brochure. (Don't get upset, Lauren, there's no copyright notice on it.) Page 1: Reach family members by pushing 2 buttons with INTERCOM. Reach anyone on any Touch-Tone line in your home instantly by pushing just 2 buttons. No more yelling from the kitchen to the office or kids' room. Indispensable in an emergency! Page 2: Answer any ring from any phone with CALL PICKUP. Call pickup lets you answer Grandma's phone from your bedroom. Or your business phone from the kitchen. So you never have to make a mad dash for a distant phone again. Page 3: Switch calls from one line to another with CALL TRANSFER. Let your phone do the running around. Send your wife's calls to the greenhouse, business calls to the office or studio. Page 4: Put calls "on hold" while you consult in privacy...with CALL HOLD. Here's the simple solution for all those times when you're on the phone, yet you want to consult with your family--or even answer another call--without being overheard. Page 5: Talk with family, friends or business associates in 2 different places at once--with 3-WAY CALLING. Visit with long distance relatives or friends on birthdays or anniversaries...arrange local church, school or club activities--all on a 3-way call right from your home. Page 6: Never miss a call--even if you're already on the phone--with CALL WAITING (OPTIONAL FEATURE). If someone is trying to reach you while you're on the line, a gentle "beep" lets you know. Page 7: Make sure calls reach you wherever you go with CALL FORWARDING (OPTIONAL FEATURE). Instead of being tied to your house to answer calls, have them follow you. Page 8: Distinguish between inside and outside calls with DISTINCTIVE RINGING (OPTIONAL FEATURE). Distinctive Ringing lets you know whether a call is from outside (2 rings) or inside (1 ring) your home. Page 9: Reach important numbers in seconds with CONVENIENCE DIALING (OPTIONAL FEATURE). Convenience dialing lets you reach up to 30 emergency or frequently-called numbers by pushing just 2 buttons. Cuts search-and-dial time by 80%! Page 10: Away or busy? Let someone else answer with ALTERNATE ANSWERING (OPTIONAL FEATURE). If you've stepped away--or you're already on the phone--Alternate Answering automatically routes your incoming calls to another line so someone else can answer--and take messages for you. There's a card stapled to the front of this cornucopia of information: you can call Bonnie Fair toll free at 415-572-6330, although if you don't live in the Northern California Pacific Bell service area, she would probably be happier if you called your local business office if you want to know more. She did tell me that no extra equipment was necessary, in fact, it's not even necessary for an installer to visit your home, although I don't know how they could make one phone in your house ring and not all the others without some kind of special hardware somewhere! -- Steve Vance {dual,hplabs,intelca,nsc,proper}!qantel!stv dual!qantel!stv@berkeley Qantel Corporation, Hayward, CA ------------------------------ Date: 15-Apr-85 13:35:42-PST From: jbn@FORD-WDL1.ARPA Subject: Re: Premier service To: telecom@MIT-MC.ARPA Cc: jbn@FORD-WDL1.ARPA This is much like Centrex II, an early ESS-based service allowing large organizations to have internal dialing and other PBX-type services without on-premises switching equipment. Everything was done in the CO using software in the ESS. There was an operator position for the ``PBX operator'', but it was just a very specialized terminal into the ESS. Providing this service for small organizations makes a lot of sense. The big guys buy their own PBX systems today.

I assume that it's a regulatory/billing problem. Sometimes I see another 800 number for use within a state, so (at least in some cases) it's not just the cost. Aren't the billing computers smart enough to keep track of the different rates? I'd think crossing a state line would be just one more complication among many. ------------------------------ Date: Tue 16 Apr 85 21:25:16-EST From: Robert Scott Lenoil <G.LENOIL%MIT-EECS@MIT-MC.ARPA> Subject: Re: TELECOM Digest V4 #179 To: TELECOM@BBNCCA.ARPA Date: Fri, 12 Apr 85 7:56:04 EST From: Carl Moore (VLD/VMB) <cmoore@Brl-Vld.ARPA> To: telecom@Brl-Vld.ARPA Subject: 718-976; areacode & zipcode around LA I called 718-976-3838 again recently, and just got phone bill showing NEW YORK, NY again for it. (718 should be fully cut over by now, so this seems to be a permanent arrangement?) The switch to 718 for the boroughs of Brooklyn, Queens, and Staten Island did not bring an accompanying change in boundaries - they are all still part of New York City, thank you. (This is just the sort of thing us non-Manhattanites feared would happen when we lost the 212 area code.) -Robert ------- ------------------------------ From: ihnp4!homxa!hood@Berkeley Date: 17 Apr 85 09:39:03 CST (Wed) To: ihnp4!ucbvax!telecom From: Ron Hood Subject: 1.544 Mb formats I've noticed some discussion on the formats for T1 carrier, and DS1 streams during the last few digests. While I don't claim to be an expert I can offer a few pointers to good sources. A sort of standard reference in the former Bell System is the "Red Books"; a three volume set published by Western Electric covering everything you could ever want to know about transmission. I don't know if the set is available to the general public, but you might look around. The title is "Telecommunications Transmission Engineering" and was published by WeCo Technical Publications, Winston-Salem, North Carolina. A second document is Compatibility Bulletin 119 (formerly TA 34). This contains the "Interconnection Specification for Digital Cross-Connects" which is a round about way of saying that it has the specs for the DS-1, DS-2, DS-3, and DS-4 formats. This is alleged to be available from: Publishers' Data Center, Inc. P.O. Box C-738 Pratt Street Station Brooklyn, New York 11205 (212) 834-0170 A slight clarification of terms is that a T1 line is a digital metallic carrier system developed by AT&T while a DS-1 stream is a standardized 1.544Mb interface. In practice the terms are used interchangeably since the only difference is that T1 will sometimes have a DC offset to power remote repeaters. I don't advocate misusing the terms, but you'll find it where ever you go (similar to baud vs bits per second). Ron ------------------------------ End of TELECOM Digest ******************************
