The simple passive hybrid used in most telephones would be incapable
of providing sufficient transhybrid loss to be acceptable for use with
an amplified earpiece. Sidetone is simply the leakage from an
imperfect hybrid and is not something that can be adjusted. To do
that, one would have to use an adaptive hybrid and then intentionally
and adjustably feed transmitter audio into the receiver. The best
adaptive hybrids are executed in the digital domain, something that is
out of the question for use in a simple telephone.

The usual workaround for an amplified handset is to employ a noise
cancelling transmitter. This cuts the ambient noise pickup and the
resultant sidetone distraction.

An effective trick is to put your hand over the transmitter. This
blocks the ambient noise pickup. It is surprising to see people on the
telephone in a noisy environment putting a finger in the opposite ear
in order to hear the caller on the line more clearly. It is a much
more effective practice to cover the mouthpiece. The brain can
differentiate signals that come in through separate ears with little
difficulty, so what you want to do is to reduce as much as possible
the distractive noise coming into the same ear as the distant caller.

In reference to Paul Schauble's request for a "Selective Ringing Call
Director", I have two starting points:

1.  Home Automation Lab (posted in this newsgroup, in fact).  I called
their number, 1-800-HOMELAB (1-800-466-3522), and they say that they
have such a product.  I am waiting to receive their catalog.

2.  BLACK BOX (R).  Their September 1992 catalog lists a product
called DRD-4 that automatically routes distinctive ring services from
one incoming phone line to up to four devices. $ 139. Phone 1-412-746-5500.

	No personal experience with either product, but I'm
investigating both of them.

Maybe I'm wrong, but I can "explain way" all of Mr. Silvernail's
concerns by referring him to the relatively new, and only now becoming
effective, Americans With Disabilities Act.
 
The Act has one complete section devoted to Telecommunications.  This
is the part that mandated the Relay Services we've read about in the
digest some time ago, where an operator relays messages between the
TDD system and voice callers.
 
Another part of the Telecommunications section of the ADA requires TDD
terminals in pay phone installations of some size > X.  If The Phone
Company is allowing for equal access to the TDD, the possibility of a
wheelchair customer might explain the low keyboard height and the
slantex keyboard.
 
Disclaimer: I've not personally seen one of these new payphones yet,
and also I recognize the increasing marketing attractiveness of some
computer connection to a payphone.  But what I've heard, and the
timing of their appearance, suggests to me that these phones were
driven by the ADA.  Perhaps ongoing market research into who uses them
and how will lead to increased availability of computer communications
capability for business travelers as well.

No, it wasn't, the airport interior sequences were filmed at the Tom

That's why _PacBell_ pay phones were everywhere.  The snowy exterior

I'll be moving from Chicago to NYC/NJ shortly.  I'm looking at getting
a second number added to my phone, as well as getting an additional
phone in the NYC/NJ area.  In my travels it seems that none of the
dealers are particularly excited or even interested in signing me up.
It's like this is the price, here's the contract, sign it if you want.
I've been trying to figure out which company (Bell Atlantic or Cell
One) has better service, rates, coverage, etc.  None of the dealers
even care to discuss this.  Does anyone have an opinion as to which
carrier is better?

In Chicago Ameritech will give you something like $150 of credit if
you have a phone and sign up with them. Some dealers have giveaways to
customers who have phones and sign up with them. Is there any similar
deal in the NYC market?

Your fallacy is in the use of the '1' with the seven digit number. In
area codes that contain "informal" exchanges (N1/0X), the '1' becomes
the clue to the CO that what follows is a ten digit number.  Before
informal prefixes, Manhattan, as well as the entire metro area did not
require a '1' for any long distance. (At least my uncle's phone in
North Tarrytown did not in 1967 when I visited.) When the informals
came in, so did the '1', which was required before dialing an area
code.

No new command is needed, the get command will do just fine, you just
need to give it two file names ... get remote-file-name  local-file-name.

It just defaults local and remote to the same name if only one is given,
so:

get READ.ME.FIRST README.FIR

will do just fine.  Otherwise all us UNIX folks would find getting the
file README.FIR;2 from a VAX site a pain. (the ;2 would drive us nuts,
as the ; is the shell delimiter for end of command.)

The following report is from UPI (looks like it's still around):
 
A huge traffic jam developed in front of Yangon's (formerly Rangoon)
post office on Monday morning as several hundred people jostled for
telephone application forms from a narrow window of the building.
 
The forms are for a telephone connection in the city for a lump-sum
payment of US $1,100, according to an ad in the government-run {Working
People's Daily News}.
 
Private telephone connections have been suspended for many years.
Demand has risen considerably with the mushrooming of Myanmar
(ex-Burma) and foreign businesses and the increase in the city's
population, estimated at four million.
 
Demand has been so strong that there have been reports of installed
telephones being sold by the original subscribers for huge profits,
even though such sales are forbidden by the Myanmar postal
authorities.

There are basically two types of "public airphones:" The older phone
is the one on the wall of the cabin (typically up front or in the back
of the cabin, by the bathrooms).  These units require one to put a
credit card into a slide and the card is held while the uncorded
handset is released.  The newer airphones can be found at your seat,
typically in the back of the middle seat in front of you.  You use
your credit card to unlatch the corded handset.  You then swipe the
card on the card-swipe unit which is on the seatback.

The prices have gone down and the quality is much better though I
suspect it has little if anything to do with the actual units.

Data Comm Folks,

I am confused about the T1 usable rates.  My understanding is that the
T1 lines can come in two speeds:

1. 1,344 Kbps i.e. 24 channels @ 56 Kbps each;  OR
2. 1,536 Kbps i.e. 24 channels @ 64 Kbps each.

Now, what do I need to do in order to get the higher 1,536 speed: Is
this the function of the terminating CSUs, the phone company circuit
or both? The difference is 192 Kbps which is quite a lot and we would
like to take advantage of this extra bandwith if possible.

Do I need to tell the phone company when I order the circuit that I
want the 1,536 Kbps line?

My understanding also is that if the two CSUs are connected back to
back via an in-house circuit less then 6,000 long they can indeed get
the 1,544 Kbps usable bandwith rates since no framing bits are needed.

Thanks in advance for any info on the subject.

I am sorry if this is an FAQ, but I wanted to know if a cellular phone
purchased domestically and being serviced by GTE MobileNet, would work
overseas, in Europe and Asia. I looked through several issuess of
Telocater but did not find any reference to the above question. From
what I hear, UK, Canada and Mexico are the only places where one could
use a U.S. cell phone.

On another note, I was told by a local cell phone vendor that GTE is
putting in a new switch this weekend and this would cause all the
cheaper cell phones like "Diamondtel", "Uniden" etc. to stop
functioning. They also said that Cellular One will be putting in new
switches in a year and then these cheaper phones will not work
withCellular one as well. Is this true, if it is what is going to
happen to folks who have bought these phones.

I seem to remember reading (in an ITT manual, I believe) that the
sidetone was generated by *intentionally* unbalancing the hybrid
transformer.  Also, a friend of mine once had a phone with a "broken"
hybrid which produced *no* sidetone at all (or at least very little).
This always annoyed me as it fooled me into thinking the phone had
gone dead.

Lesse ... ah here's something.  In {Understanding Telephone
Electronics} by Howard W. Sams & Co.  Chapter 2, under Sidetone: "For
the hybrid used in the central office exchange, the balancing network
is adjusted so that no transmit signal appears at the receive
terminals and no receive signal appears at the transmit terminals.
However, for the induction coil [earlier explained to be an historical
name for the hybrid in a telephone set - hgr] arrangement in the
telephone set, the balancing network is intentionally unbalanced
slightly so that a small amount of the transmit signal is also fed to
the receiver of the talking phone.  This signal is called sidetone."

Admittedly, this isn't the most authoritative book ever printed on the
subject of Telecommunications, but it was handy.  Is it wrong?
