Different ownership is the answer. The telephone system in
Kingston-upon-Hull is run by Kingston Communications, a company which
is owned by the City of Kingston-upon-Hull. (The telephone service
there used to be operated by the city directly, but I think the
decision to run it as a separate company came in response to various
controls imposed on municipal governments by the central British
government.) In the rest of the U.K., the franchised local carrier is
British Telecommunications PLC, which used to be known as British
Telecom and now likes to be known simply as BT.

Around the turn of the century, a number of British city governments
ran their own telephone companies. Most of these were eventually
purchased by the National Telephone Company or by the post office
(which eventually acquired the National Telephone Company). Even
before these acquisitions, the post office was involved in
telecommunications through its telegraph network. I am not sure why
Kingston-upon-Hull stayed in the phone business whle other cities sold
their telephone departments.

Hull has slightly different dialing than the rest of Britain. In Hull,
you dial two-digit numbers beginning with 9 for the operator, or for
the business office or for repair service ("faults reporting"). From a
BT phone in the rest of Britain, you dial three-digit numbers beginning 
with 1 for the operator or for repair service.

Hull has done some other innovative things that I can't think of right
now.  If your local library has British phone books (probably on
microfiche), check the introductory section of the Hull directory for
more information about the city and its telephone service.

The most obvious difference between Hull and the rest of the United
Kingdom is in the older-style phone booths. Recently-installed phone
booths are metal and plastic, but in the days when the post office ran
the phone suystem in the UK, the standard phone booth (or "call box")
was made of cast iron and was painted red, to match the post office's
street letter boxes ("pillar boxes"). But in Hull, because the phones
there weren't run by the post office, the cast-iron phone booths were
painted white.

A proper discussion of British pay phones would deal with Button A and
Button B, but I will leave that to someone else. In practice, an
increasing number of British pay phones work with stored-value cards
or credit cards rather than coins.

If you're serious about this, you need to check out ALL the
requirements as published by ANSI, EIA, TIA, and Bellcore.  I'd start
with SR-TSV-002275, "BOC Notes on the LEC networks -1990."  Also, the
FCCs part 68 registration would be a nice idea ;^)!  BTW, with Dual
Tone Multi Frequency (DTMF),the tones are both present, they're not
averaged!

I'm sure exactly what you mean, but DTMF stands for Dual Tone,
Multi-Frequency, meaning that there are going to be two tones at once
(and at two different frequencies). For example. if you hit a '1' key
on the telephone, you would really be hearing a 697hz and 1209hz tones
simultaneously.

In your project, are both of the tones playing at the SAME time? If
not, it will not trigger anything on the telephone.

Just for information, the DTMF telephone tones are as follows:

1 - 697/1209Hz		2 - 697/1336Hz		3 - 697/1477Hz
A - 697/1633Hz		4 - 770/1209Hz		5 - 770/1336Hz
6 - 770/1477Hz		B - 770/1633Hz		7 - 852/1209Hz
8 - 852/1336Hz		9 - 852/1477Hz		C - 852/1633Hz
* - 941/1209Hz		0 - 941/1336Hz		# - 941/1477Hz
D - 941/1633Hz		--------------          --------------

The largest bank in the US doesn't seem to want to keep it's New
Jersey customers.  Citifone, a service of Citibank, N.A., has a 201
area (New Jersey) access number in Rockaway, New Jersey.  Rockaway is
a premium toll call from most of Northeast New Jersey, and is more
expensive than calling their New York City access number (you can make
international calls for less than what it costs from southern New
Jersey).  They have an 800 access number, but it won't work anywhere
in the tri-state area (New York, New Jersey, and Connecticut).  I
honestly don't understand how Citibank executives can dress and feed
themselves without assistance after seeing this nonsense firsthand.
Are there any similarly large banking organizations doing anything
creative and efficient with customer services without similarly making
their customers pay through the nose for their stupid mistakes?

AT&T will offer a regular 800 number, for $15 a month plus usage which
is, if I'm not mistaken, a flat 31c/Minute.  This ties into an
ordinary phone number.  There is a charge of $30 to install it.

Sprint is about the same, except the per minute rate is about the same
as dialed direct calls.

In the case of both AT&T and Sprint, the number can be listed with 800
Directory; Sprint will take two company names for a single 800 number
with no problem; up to four can be put on a number but more than two
requires proof those names actually use it, i.e. letterhead submitted
to them.

MCI has the $5 a month 800 number, but it's a shared number; after
someone dials the 800 number, they dial a passcode.  The passcode
indicates which subscriber to connect to.

I had the 800 number service from Mid Atlantic Telecom of Washington,
DC for a while.  It's $8 a month plus usage which ranges from 16c to
31c per minute depending on distance and time of day.  Also, Mid
Atlantic does an additional thing that's surprising, the "Caller ID
List" or "ANI List", in which included with your bill is a printed
listing of the time and date, length of time and calling number of
everyone who called your 800 number.

MCI also has a standard non-shared 800 number, but it's more
expensive.

I saw an announcement on here for Cable and Wireless' 800 number which
allows the customer to change the destination number on his own.

Also, Sprint allows you to have an 800 number route to a specific
place depending onthe caller location.

So here's your answer: Get Sprint's 800 number. In your area code,
have calls to that 800 number routed to the other party; in their area
code, have calls to that 800 number routed to you.  Or substitute
"areas you travel in" for area code.  If you're on the West Coast and
they are on the East Coast, it's real simple; put calls in the Pacific
and Mountain States to direct to them; put Central and Eastern Time
Zone calls to you.

Not quite.  Calls in the stable ("talking") state will be lost.
However, call attempts (or recall attempts) will be routed around the
cause of failure.  Of course in a xx second program, the fine points
of all of this can not be adequately discussed. The point they are
trying to make is that Bell Canada provides dependable service without
a lot of techno-babble.  BTW, this rests on the assumption that the

The DTMF detection equipment looks for BOTH tones, not an average of
the two.  There are audio filters that detect the individual tones and
I'd guess the "average" of the tones being created by your program
does not actually consist of the individual tones themselves.

The duration of your tone also seems a bit longer than necessary.  If
you ever listen to the outpulsing of any auto dial phone you'll here
an entire ten digit number outpulsed in about two seconds.  You could
probaby shorten the 0.5 second tone length to about 0.2 or 0.15 seconds.

I too had this problem several years ago in San Jose, CA.  I waited

Actually, you have it backwards. GTE is the LEC in Dallas (but not Ft.

fax machine could be used both as a scanner and as a printer.

She would like a small and inexpensive piece of euipment with two
modular telephone jacks with just enough "smarts" to supply a dial
tone and appropriate ringing signals.  The smarts could be a person
listening on a speaker and using buttons to generate the signals at
the proper time.

Can some one tell me where such equipment can be obtained from and
give me company names, addresses and telephone numbers.  Estimates of
price would also be useful.
