If it connects at all it's set up properly, all we're doing now is
tweaking.  You are probably getting a noise burst on (either side of)
the line long enough to cause the modem (at one end or the other) to
think it's lost the carrier, so it hangs up.  There should be a DIP
switch or a command to tell the modem to wait a bit longer after
losing carrier before it hangs up.

This is a much more popular idea in Europe, where the popular radio
stations tend to be national (e.g. BBC), and languages vary over short
distances.  I don't think it will work in the states; as the article

approved for a decade, and it still hasn't taken off.

We At Cylink also have SecureCell, a DES-encrypted cellular phone. It
is compatible with our other DES telephone encryptors. As for

Here is some generic information I've picked up.  Someone else will no
doubt have the exact answer.

Approximately just before the second or third ring (depending on the
system), the information is sent as a data stream about 300 baud
between rings.  In short, this is why modems can be built to take the
caller ID information.

Try GrayBar or Anixter Brothers, both of which are national firms with
distribution locations in most major metro areas.

For best selection try:

Jensen Tools:  602-968-9662
Specialized Products: 1-800-866-5353

These two firms specialize in selling all manner of "real" telephone
installation equipment: test sets, tone generators, tone detectors,
cable splicers, wire strippers, toolbelts, punch down tools, etc. etc.
you ame, they probably carry it.  They also sell complete tool kits.
They've got lots of stuff available, but prices are steep.

Yep, they're radio phones powered by photocells and rechargable

Transmissions are usually normal FM voice; frequencies vary by state

I haven't seen anything on this, and I'd expected people to be jumping
all over it.

Sometime on Thursday evening 10/8/92 the SPRINT switching centre in
Fairfax, South Carolina, went down completly. Various "rumors" abound,
most of which involve the switch being under 18 feet of water. We're
located in North Carolina, and all our SPRINT switched service is
routed via that switch. Certainly on Friday people in the area with
SPRINT 800 service were not getting any calls sent their way.

It's 16:00 EDT on 10/13/92, still no service. We have dial-tone on the
trunk, and get an all circuits are busy if we try and make a call.
Refresh my memory, didn't Congress go ballistic after the AT&T outage
around New York? Here we are going on the third business day, and not
a peep out of any news organization.

[Moderator's Note: I put a short article about this in the Digest on
Tuesday. I don't know how deep the water is, but yes, the underground
switch was flooded. Apparently Sprint had no provision for backup
routing of any sort. The word is the service will be out for a long
time; maybe a month or more. A lot of the customers affected have
simply made arrangements to switch their service over to AT&T or MCI
permanently. For the life of me, I cannot understand why any telco
would bury their switch underground knowing how vulnerable they are to
dampness and other conditions.  Even here in Chicago, when we try to
call over to that part of the country if we use Sprint to start the
trip from here the calls are just bombing out. We get a rapid busy
signal. You'd think Sprint might at least pick off their traffic going
that way and hand it off to AT&T or someone else to make things a
little easier.  Would anyone from Sprint care to comment?  I'll give
the article priority attention here if they do.   PAT]

Another instance when calls to a busy line are recorded, is for police

Does anyone know offhand what sort of signalling scheme ROLM uses
between a telephone deskset and their digital pbx?  A cursory
inspection of the innards of my telephone reveals an impressive array
of custom transformers, two big LSI chips (one by Exar, one by TI),
and the usual mess of discretes.  Is the signalling they use
compatible with either ISDN S/T attachment, or perhaps like the
Motorola UDLT format (B+D rather than 2B+D)?  The basic signalling
cell seems to be about four microseconds.

X-Telecom-Digest: Volume 12, Issue 769, Message 9 of 9

There was a discussion a few days ago about a problem with a tip/ring
reversal on a SLC 96 and people wanted to know why SLC 96's were still
designed to be polarity sensitive.  Well, according to some experts in
the business:

1. Ground start lines must distinguish between tip and ring correctly
in order to handle the ground start protocol.

2. Early CO channel units were polarity sensitive and the ringing
detector was on one side to ground. This made the channel unit appear
to have a different resistance to ground on tip versus ring. This
resistive "DC signature" is used by testing systems to verify that a
good channel unit is installed.  Therefore, the DC signature was
grandfathered for subsequent designs even if they could be polarity
insensitive. In fact, today there are many DC signatures for detecting
many services such as POTS, coin, PBXs, etc.

3. Proper installation is very important in the telephone business
because there is a lot of "churn" (service changing).  If a line is
installed with the wrong polarity and an insensitive channel unit used
on it, then if service is changed in the future, (say from loop start
to ground start) it would delay the installation while the previous
trouble is fixed. This is a significant problem because frequently
different craft are used for the initial office wiring versus just
plugging in circuit packs for service.

Um, wait a minute.  Admittedly, these could be different manufacturers,
but here's what I recall from my one use: When I opened the door,
there was a handset hanging in a dead hook (as Chin said) but there
was also a big flashing button that said "Press Me" or some such.
When I pressed it, the instrument made DTMF noises, waited through
some clicks (connection now established?) and then (perhaps in
response to the other end?) made *more* DTMFs (*not* seven digits, as
I recall).  My guess was that the second set was after a connection
had been made to CalTrans, but before a human was on, and it
identified the instrument.

Hitting */# does not change anything (either on the phone, or on the
handheld pad) - both simply send their beep, and the gate continues
pulsing. That's apparently the problem -- the gate seems not to have
noticed that the connection has been established, and pulses on and
on.

I have fould a very silly solution in the meantime -- I switch
(mechanically :-) ) the phone into the pulsing mode and dial; in this
case, the gate accepts me as a pulser, and doesn't switch into the
converting mode. After the connection is established, I switch into
the touch tone mode, and the beeps are passed through.  But this
solution is not very smart.

Anyhow, thanks,

Speculation: perhaps the phone box detects the permanent magnet that
is likely to be in the handset's earpiece.  A reed relay would be
low-tech and reliable (like the burglar-alarm door switches), but I
question if it is sensitive enough.  A Hall-effect flux detector would
work, but is it economical enough?  A metal panel shouldn't bother a
STEADY magnetic field, although it attenuates an alternating field.

While talking to a nice lady at New England Tel about residential ISDN
this morning, she mentioned that NET has re-filed for calling number
delivery, but didn't know what blocking options were to be offered.
Does anyone else have the details?

She was remarkably well-informed -- "Is the interface 2B1Q?"  "No,
your CO is still just AMI but should be equipped for 2B1Q next year."
The basic rate is just $8/month above POTS, which includes both B
channels equipped for voice, with the same rates as for POTS calling,
i.e., free local calls.  Data is $5/month extra and all calls are
charged at the message rate, 1.6 cents/minute plus 1 cent per call.

I told her that like everyone else I'd probably disguise my data as
voice, live with 56KB and occasional dropped frames, and save big
bucks.  She said that the tarriff said I wasn't supposed to do that
but agreed there was no way they could tell.
