It seems appropriate to remind that cellphones aren't particularly
private or secure ... which is probably an issue when discussing
patients and their particulars.

Because for some historical reason it has its own phone company
independent of British Telecom.  Maybe some reader in the UK can
explain the history of it.

Some trunking systems implement "protection switching."  There is an
extra path in parallel with one or more of those actually in use that
can be quickly switched in before calls are dropped.  Most subscriber
carrier systems have this option, including DMS-1U, DMS-1, and even
the SLC-96.  It was very common in microwave trunking systems to
reroute around squalls--remember the connections that got noisier and
noisier, then, clunk!, a clear connection?

Your only options would appear to be using a leased line or radio
system to an alarm monitoring company.  I know of fire alarm systems
which use a metallic leased line (not always available) which when cut
cause a 'trouble' indication to the monitoring station.  They (the
municipality) will roll fire trucks in that instance.  I'm sure there
are private alarm companies which offer similar services, however the
cost (for a leased line) would be high.  Your cheapest solution might
be to buy a cellular phone and use it as a secondary (or primary)
means to notify the alarm company. I'm not sure how many alarm systems
offer this as an option, but they should....

Due to historic accident Hull has always had a separate Telephone
Company from the rest of the UK: basically in the early days of
telephony the original legistation allowed local councils to
authorise/run local phone services as well as the Post Office.  Hull
was the only place that did this, that didn't hand the phone
operations over to the Post Office.

Hence Hull now has a different telephone company (Kingston
Communications) from the rest of the UK providing local loop
connection. They offer complete equal access to BT and Mercury for
long distance and a choice of different local tarrifs, one of which is
"free" local calling. There is still the option of metered local calls
as well.

You certainly shouldn't be able to, since commercial video IS 30FPS ...

Actually, to be absolutely accurate, NTSC (Never Twice the Same
Color... :-) defines two half-frames or "fields", each of which
consists of 1/2 the lines (525 in total) on the screen, transmitted in
an interleaved manner.  So there are really 60 fields transmitted each
second.  But in terms of full frames, there are only 30.

Animation does not use 30FPS (except direct to video animation).  They
use 24FPS, just like the movie industry.

MCI is running an ad; it appears on page A-16 of the Nov. 4
{Washington Post}.  It mentions the 800 number portability option,
"For the first time you, not AT&T, will own your 800 number."  (Funny
how it neglects to mention that MCI {also} will no longer own the 800
numbers.)

This advertisment has a marker on it, "The MCI 100 Day Report, #1", so
I assume there will be 99 more ads, one every day I guess.

It also seems to make a veiled reference to the Clinton Election
(opportunity or disaster depending on your point of view) by saying
"Meanwhile, whether you see today as riding out the bad times, or
tuning up for the good times ..."

It also mentions when 800 number portability takes effect: early 1993.

I've seen the abbreviation 'T1' or 'T-1' here in the Digest many times
over the past few years, but I don't think I've ever seen anyone
define exactly what a T1 was.  From context, I have guessed that it is
a direct link to the local telephone company for high-speed data
purposes, or a direct link to a long distance company for the purpose
of bypassing the local telephone company.  But I'm not certain either
of those definitions is correct or tells the whole story.  So, could
someone please summarize what a T1 is and why anybody would want one?
Thanks.

	In a discussion today, the idea came up of using a single DS1
or T1 line to handle incoming calls to a BBS type system instead of 24
individual phone lines and 24 modems driving 24 serial ports.  It
seems that we should be able to have a single DS1 line driving a
single interface board in the computer that would sort out all the
data (figure out which user is on which line and is in which time
slot, etc.).  This would compare favorably to all that extra hardware.
To the outside world, though, it would look just like 24 dial in
modems, except, perhaps, people whoe have ISDN or switched 56 lines
could dial in at that rate instead of some rate limited by a modem.
Anyone doing this?

Proctor and Associates makes the 49200 Phone Demo II.  It sells for
$259.95, and gives you real dialtone, ringback tone and ringing via
two RJ-11 jacks ... a miniature Central Office in a box.  There is
also a basic four-line version, and a fancier four-line version that
emulates CENTREX and Caller-ID.

Leave the DTE speed alone, or make it faster (57.6) if your system can handle
it. If you have the DTE speed at the line speed, there is NO POSSIBILITY of
compression doing anything for you. You should use flow control that is out 
of band RTS/CTS style.

The 38.4 you saw was where the factory defaulted it. 38.4/14.4 isn't even 3:1,
and ZyXEL to ZyXEL you can get 16.8 or with your + maybe 19.2, so 38.4
is hardly enough to get much compression. Use 57.6, and simply LEAVE it there.

The ONE and maybe only fault with ZyXELs is that they can't do 115.2kb DTE 
speed.

Subject: Help Requested -- Zoom 9600/v.32/MNP5 modem performs erratically
Date: 10 Nov 92 13:08:44 GMT
Organization: University of Pittsburgh

I need some help configuring a 9600 baud modem.

Specifically, I'm using a Zoom v.32/MNP-5 modem, external version, ROM
version 1.200, with ProComm Plus for Windows. No matter how I configure
the modem or ProComm Plus, the modem performs erratically. For example,
from a cold start, the modem may accept the configuration string,
successfully dial a number and maintain a connection, and then go on-hook
in accord with the appropriate command. But within a few minutes to a half
hour, it ceases to respond. In some instances, it will not accept the
initialization or respond in any other way. In other cases, if it is
turned off and then back on, the software will run the initialization
string, the modem will respond at least to the extent that the LEDs
indicate response, but it will not dial. 

(At the recommendation of Zoom Telephonics' technical support department,
RTS/CTS flow control is is on, the autobaud detection feature is set to
off, and the speed is locked at 19,200. The initialization string issued by
ProComm Plus for Window is "AT&F&C1&D2^M" or
"AT&F&C1&D2^M~~~ATS48=128^M~~~ATS0=0^M," with performance being at least
outwardly equal in either case. Also, the command "AT \E1" has been issued
to match line impedance.)

Any advice? Suggestions? I'm wondering if there is a problem with the
NVRAM, since the modem's behavior suggests that it may not be able to
maintain a configuration. But I'm open to any and all suggestions,
especially those that will work!

Are you saying the terminal won't even let you TYPE to the modem 
unless carrier detect is high?  If you connect the terminal to the 
modem and type characters, the modem doesn't blink its SD (Send 
Data) light?  If it DOES blink, then you ought to be able to type an 
"AT&C0&W" command line, even though you don't see the characters 
being echoed back to you.

If that doesn't work, what you can do is tie any of a number of 
signals from the modem over to the carrier detect signal.  The most 
practical is to disconnect the wire from pin 8 on the modem end 
(DCD) and connect it to pin 6 (DSR, which should be held always on). 
Depending on the cable, you might be able to just push out the pins 
from the plug and shuffle them around. Be sure to check with a 
voltmeter to make sure the modem is holding DSR on before going 
through the trouble of changing the cable.

Of course, there's one more alternative:  you could temporarily move 
the modem to a PC which doesn't care if DCD is high.  Fire up your 
favorite comm program, type the AT&C0&W command string to set DCD 
always on and save it in the modem's non-volatile memory, then take 
the modem back to the terminal.
