This is the way the reps WANT to place the order -- that doesn't mean
you have to take it :)

Ask them to install No Answer Diversion as well as Busy Diversion when
the set up your order.  They will try to tell you it can't be done,
but it can.  You also may want to get regular Call Forwarding, as you
can call forward your calls directly to the voice mail so it won't
bother you (sort of a Do Not Disturb function).

[TELECOM Digest Editor's Note: I am surprised you find reps who say it
cannot be done. Here it is quite common and is known as 'transfer on
BY/DA' (busy/no answer). For the former it transfers immediatly and
for the latter, after three unanswered rings the CO pulls the call
back from the subscriber and diverts it. The caller hears the slightest
pause in the ringing cadence as the CO quits ringing the one phone and
sets up the connection to start ringing elsewhere. 'Transfer on busy'
is quite similar to a hunt group, but apparently not entirely the
same.  Does anyone know why? IBT gives 'hunting' for free but charges
a monthly fee for 'transfer on busy' (which can be had without the 'no
answer' part if desired, or vice-versa).

Meanwhile, legitimate users of pagers and voicemail such as I
(computer consultant) may eventually need to go out and buy DTMF units
just to check on our messages.  As it is now I tend to avoid
non-Pacific*Bell pay phones because the off-brands are often not
programmed to think of my voicemail's exchange as local or even in
operation, or they block after the first digit.  As to drug buyers,
yeah, you have a point.  Anyhow, rotary dialing hasn't come to the SF
Bay Area yet, and I hope it never does.  It's just a nuisance.

Some of the big pager companies like Metromedia had established
policies limiting the number of calls, so at least they made more
money on the busy drug-dealer paging.  One, and I want to say it was
PageNet, charges some extremely high amount for overpages, amounting
to thousands of dollars.

Perhaps if the 7-Elevens paid better wages the kids would be encouraged
to work for them instead of selling drugs.  When I was their age I could
live on minimum wage.  Today?  Heh.  It might pay the electric bill.


[TELECOM Digest Editor's Note: When I started my working career in 1958
the minimum wage was *$1.05 per hour*, and that is exactly what my
employer, the University of Chicago paid me. I was a junior in high
school and I had a part time job as a switchboard operator when the
boards were located in the old phone room on the sixth floor of the
administration building, 5801 South Ellis Avenue. Since restaurants and
hotels were exempted from the minimum wage law, I was the rich one
among my buddies who worked washing dishes or sweeping floors in
restaurants; they got paid 65-85 *cents* per hour. After high school
when I went to work full time for UC as an operator they paid me $1.25
per hour I think, and that was enough to pay for my own apartment, but
in 1960 a nice one-bedroom apartment in Chicago along the lake cost
about a hundred dollars per month. Cigarettes were 24 cents per pack
at Walgreen's and if you bought them from a vending machine you put
in a quarter but got a penny back tucked in the celophane wrapper of
the package.  PAT]

Of course, I've heard of Minitel, since I live in Paris, and have to
use Minitel, but do it as little as possible due to the exorbitant
cost.  Who wants to pay $12/hour to make a plane reservation on
Minitel when elsewhere one can call a toll-free number?  And that
after wading through endless menus to keep you online longer -- yes,
that is done deliberately to maximize revenue -- and that all at 1200
bps using primitive graphics!  It is cheaper to call CompuServe at
9600 bps, soon to be 14.4k bps, pay $8.95 per month for unlimited
access to plane reservations and other services like weather, for
which you have to pay upwards of $12 per hour on minitel, and with far
inferior graphics when maps are displayed.

Minitel is a success due to the lack of competition, and the unfortunate
ignorance among consumers that they are paying through the proverbial
nose.

In fact, the evolution to a modern network began over twenty years
ago, and the telephone network is indeed modern, though this is often
crippled for data communications through four to one compression on
many lines, so anything over 2400 bps is impossible.

As for users' needs, it is also true that France Telecom is more
responsive, mainly because of the spectre of competition looming on
the horizon.  But, all that is at costs to the consumer which are
horrendous.  For example, it costs me more to call my wife in the
country (Seine et Marne, in the Paris region, 85km) than to call from
New York City to Los Angeles.  In fact, callback services to access
the USA have rates that make it cheaper to talk to New York or Los
Angeles than to call Bordeaux from Paris.

Now, Minitel is touting the coming new "high" speed: 4800 bps.
Elsewhere, 14.4 is now the norm and 28.8 is on the horizon.

An item that caught my eye is the charger/conditioner for cellphone
batteries. It uses intermittent negative pulses during the rapid-charge
phase, which I'm told will prevent loss of capacity due to gas build-up
at the electrodes. Is there truth to this, or is it another urban

I used to work for a company on Long Island (it was in Little Neck, I

bought by Contel.  I'm curious if they are still around and who owns

My question is this: is it possible to configure these new digital
switches for four-digit dialing?  We're a small town where we occupy
only the 848-2xxx, 3xxx, and 41xx's.  It would make things easier for
everyone.


[TELECOM Digest Editor's Note: Sure it is possible. The switch is just
told to expect four digits only if the first digit is 2 through 9; to
expect eleven digits if the first digit is 1 and some variable number of
digits (one through thirty or so, detirmined by time-outs or # as the
terminator or carriage return) if the first digit dialed is 0. Of course
all this assumes your 'small town' does not have any local calling to
anywhere other than the town itself. If local calling includes some other
nearby village -- or even if it does not, but there is a lot of traffic
on the phone wires between the two points -- then at least a few people
in town are going to get sore at having to dial eleven digits to reach
a number five miles away where seven digits formerly was sufficient.
To get around this, I guess you could make all dialing require a time-out
or # to terminate the sequence at which point the switch would then
interpret what it had been given in the context of the entire string
of numbers presented to it. You say things 'would be easier for everyone',
but would they really?  Does no one in town csll any other exchange in
the same area code beginning with a 2, 3 or 4? Do you see the problem?  PAT]

Gopher into info.itu.ch on port 70 or telnet into ties.itu.ch

V.32, v.32bis and v.34 modems use echo cancelling technology.
Essentially each modem knows what it sent and how long it will take to
echo so they ignore it. This allows each modem to use the full
bandwidth with only a slight loss in S/N ratio.

In Massachusetts we call *SP (*77) to reach the state police and the
call usually gets routed to the nearest state police barracks.  They
forward the call to the local police if it is out of their
jurisdiction.

Near the New Hampshire border your call might get routed to the New
Hampshire state police instead of the Massachusetts police so one can
call *MSP (*677) to reach the Massachusetts State Police. I think that
calling *777 reaches the New Hampshire state police from inside
Massachusetts.

    You can play games with ANI, but CAN'T use it in delivery of
Calling Number Services, since there's no PRIVACY flag tied to ANI.
Now, I'm stumped as to why you'd want to do the reverse (use CPN as
ANI), since ANI is most readily available, but CPN isn't.

Subject: Re: Horrid AT&T 2500 Sets


I concur with Randy Gellens that today's ersatz 2500 sets are cheap
and flimsy.  But I noticed something interesting at a local hardware
store.  A display case filled with AT&T telephone sets (the usual
cheap kind with chirpers instead of bells) was accompanied by a few
new AT&T "Signature" telephone sets.  One was shaped sort of like a
2500, though a bit squashed; another was in the Trim-Line(tm, no
doubt) format.  Upon examination, I saw a mechanical bell ringer
adjustment on the bottom of the 2500-style.  Even more unusual, the
set must have weighted ten pounds!  It didn't even feel like a flimsy
set with a lead weight, just heavy.

And it was clearly marked AT&T Property for Lease Only, or some such
words.  The store said it was not for sale, either.  It was a series
that AT&T made only for rental customers.  Since it's a rental,
they're responsible if it breaks, so it's made better.

I wouldn't mind buying one of these sets, but I suspect most of us
don't really want to rent.  I'm surprised that AT&T isn't making these
available to rental PBX customers; maybe they can be had if you ask,
but maybe they're only sold to residential customers.

I know that Cortelco (ITT brand phones) still makes industrial-grade
2500 sets, but they aren't sold at consumer outlets.  Maybe I'll call
up Graybar and get me some.  You'd think that retailers would
recognize a good niche market for quality telephones.  Hasn't Japan
Inc. taught them anything?  :-)

Most exchanges have their own ANI numbers, but finding them can be a
chore. I gave the ol' telco a call the other day. Nobody seemed to
know the number, although they gave me a few numbers that I could try
-- I even spoke with a technician! You might try giving them a call in
your city; just tell them that you're installing a multi-line system
in your business and you need to do some testing. And if that doesn't
yield anything, you can always use a 1-800 ANI number. The one I use
is: (800) 775-5513. Please don't abuse it; they'll just change the
number and then none of us can use it.

Subscriber Carrier.

This was usually used in places where a single house (in the U.S.)
wanted a second voice phone line but there were no extra pairs available,
and it would split the signal into two (voice) lines on one wire.

Since phone service in Europe is so frightfully expensive, I can
understand where such a scheme would be used to create the equivalent
of Party Line service.

      Heck, about eight years ago there was a phile going around
listing lots of what were described as "phun numbers".  These were
everything from various modem dialups to tone sweeps, and there was
one number that claimed to be for Queen Elizabeth.  Anyway, let's just
say that, uuuh, a phriend of mine who wasn't particularly mature at
the time called the number.  Somebody answered, "Buckingham Palace."
And my phriend asked to speak to the Queen and the guy said "That's a
good joke, can you tell me another one."  He hung up and my phriend
called back, and asked to speak to the Queen, adding that this was a
very expensive long distance call from America (well, maybe it was
expensive, but he wasn't paying for it).  He said, "I know, but it's
three o'clock in the morning."  My phriend apologized and never called
back.


[TELECOM Digest Editor's Note: I've seen lists like that. They usually
include the phone number for the Pope as well. About twenty years ago
some phreak went on one of those public tours they give of the White
House, and I don't know how he did it but he managed to rip off a copy
of the internal telephone directory listing all the direct dial centrex
numbers for top staffers and one Richard Nixon. Even though the White
House had a plug-style 'cordboard' handling the calls to 202-456-1414,
for many years there have been centrex lines there as well served out
of the Executive Office Building on its phone system. In other words,
you could dial 202-456-1414 and ask to speak with the Resident President
then in power and get politely transferred to one of his telephone
representatives (actually highly placed flunkies authorized to respond
in the Resident President's name in limited situations) or if you knew
about it, you could dial 202-XXX-2591 and ring the phone on his desk
direct in those days.

Well!! This bird made copies of the appropriate page in the directory
and sent them off to a couple dozen radical newspapers, anti-war
groups and others. It was published in quite a few 'underground'
newspapers at the time to everyone's delight except of course the
Chesapeake and Potomac Telephone Company employees assigned to the EOB
and White House telecom office who suddenly had the task of changing a
lot of phone numbers in a hurry. Poor President Nixon ... he alluded
to 'the problem' in one of his press conferences once during the
interim of a week or so between when the listing first was made
public and the time it was in all the papers and the telecom office
wised up and began changing all the internal centrex numbers.  PAT]
