Re: TELECOM Digest V4 #31 RJ11 jacks with punch-downs ---------------------------------------------------------------------- Date: 6 March 1984 00:29-EST From: Richard P. Wilkes <RICK @ MIT-MC> Subject: TELECOM Digest V4 #30 Note on MCI-MAIL: To send an electronic message between two people costs $1, regardless of how long it takes you to compose, edit, address, and send your 7500 character message. Whether you use 300 or 1200 bps doesn't matter. Let's compare that to CompuServe: At 300 baud, the price is $6/hour. That gives you roughly 10 minutes to get into EMAIL, address, compose, and send your message. No biggy if you are uploading, but tough for the typical typist. At 1200 bps, the price is $12.50/hr. You now have only 5 minutes. This is the price of sending the message only. You can, of course, address it to more than one person at no additional cost. But, it will cost your recipient to read your message. At 30 cps, it will cost someone roughly $.40 to read the same 7500 character message, assuming that he doesn't need to pause, file, or reread the message. 1200 should be less, but few people can read at that speed and would need to pause the output. Add to this the fact that you can only use non-prime time for these rates. Prime time is substantially more. For $1 per message ($2 delivered on paper), MCI mail seems to be quite a bargain. My only concern is whether they will end up making money. Each welcome pack costs $1.87 to mail plus materials (at least $1). Connect time is not charged. They are going to have to send a lot of mail to make a reasonable return. We'll see. -r ------------------------------ Date: 6 Mar 1984 02:50:43-EST From: ima!haddock!johnl@CCA-UNIX From: John Levine, INTERACTIVE, 441 Stuart St, Boston MA 02116 From: (617-247-1155) <johnl@haddock.UUCP> Subject: Re: 950-xxxx from Charge-a-phones I've found pretty inconsistent results when trying to call 950-1088 from pay phones, either the kind with or without coin slots. For example, at the Boston airport (617-569) pay phones ask for a dime if you dial 950-1088 or 1-950-1088, but the calls go through directly if you dial 0-950-1088. I was in New Haven last week, and found that calls went through on phones in 203-789 but asked for a dime in 203-785. (I thought those two were physically the same exchange. They're both all over downtown New Haven. Hmmn.) I also found that SBS considers New Haven to be part of New York city, since my New York validated SBS number worked, and dialing random digits got a recording that said it was in New York. They're certainly not in the same LATA, so I'd be interested in what might be going on. If I called somewhere in Connecticut, would that make it an interstate call since they "think" I'm in New York? I assume that 950 numbers get supervision, but can they tell the calling number and other CCIS goodies?

I'm just very disorganized. ------------------------------ Date: Tue 6 Mar 84 00:46:03-PST From: David Roode <ROODE@SRI-NIC> Subject: USOC list Location: EJ286 Phone: (415) 859-2774 I have been told by someone at AT&T that AT&T publication 47101 contains a descriptive list of all the USOC's. The address I have for ordering AT&T publications dates from 1979 with on-the-fly updates from an AT&T customer service technical representative and is: Business Premise Engineering Data & Special Systems AT&T Communications 295 N. Maple Ave Baskenridge, NJ ------------------------------ Date: Tue 6 Mar 84 09:48:36-MST From: William G. Martin <WMartin@SIMTEL20.ARPA> Subject: Things that go "ding!" in the night... Ever since we bought a cheapy electronic phone, which we use in parallel with the old rotary-dial model on a rotary-only line, we have heard the chirp of its ring at odd times of the night, mostly at 2AM or so, and sometimes during the day. I always figured that it was some sort of CO battery switch-over or the like, sending a transient down the line which wasn't enough to overcome the mechanical inertia of the bell ringer on the old phone, but which triggers the electronic ring circuit for a single chirp. Another odd thing about this set-up is that on SOME, but not all calls, the old phone will ring, and the new electronic one will not. On most calls, both ring. Every fifth call or thereabouts, the electronic one remains silent while the old phone rings away merrily. We don't use the ringer cut-off switch on the electronic phone, so it isn't that it has been left turned off. I have sometimes let the ringing continue to see if the electronic phone will begin ringing sometime during the series of rings, but it will never start if it didn't start at the beginning. I cannot explain this at all...

Our office, attached to a Dimension* PBX uses the 8-wire jacks, with two outlets in each receptacle. I am sure that other 8 or 6 wire jacks are available.
