I'm going to France for a coupla weeks and am going to want to be
calling my sweetie here in CA.  Whats the cheap(est) way to be making
these calls.  Are there COCOTs in France to look out for?

Intelsat to buy new satelites.
{Washington Technology} September 24, 1992, Page 43

   Intelsat's Board of Directors has approved the procurement of new
satelites and launch services.  The cooperative will buy two Intelsat
VIIIs and an Intelsat VII-A.  Bidders for the new hardware include:
Arianspace, China Great Wall Industry Corporation, General Dynamics,
Rocket Systems Corp., and the Russian Space Agency/Salyut Design
Bureau.  Intelsat Director and CEO Irv Goldstein said a decision could
be reached as early as December.

Hawaiian firm wins PCTN award.

   Intelsat just gots its first real taste of competition.  Columbia
Communications Corp. of Honolulu will be the satelite provider for the
DOD's Pacific Consolidated Telecommunications Network (PCTN).

   As a member of a team bid including Sigcom, a little-known [SBA
Minority/Disadvantaged Business] 8(a) company of Whitesett, N.C., and
MCI, Columbia will be sharing the $100 million contract.  Three of the
six bidders for the contract planned to sub to Columbia because of its
highly competitive rates -- 30 percent less than Intelsat.  The other
bidders, including AT&T, went with the traditional carrier.

   The contract represents a clear victory for Columbia who spent
years fighting a hydra of regulations, court battles, and Intelsat
itself to gain an FCC satelite license.

Matt,

The short answer is that the telco transmission equipment and your own
terminal equipment are the driving factor.  You must be able to use
the B8ZS zero-code suppresion standard to achieve 64Kbps data rates on
a per channel basis.  See below for the long answer.

The data rate over each channel of the T1 carrier is dependent on a
couple of items, one being the use of "in-band" signalling, and the
other being the zero-code suppresion standard being used.

Each of these uses will occupy/corrupt one data bit in the data stream.

By "in-band", also referred to as "robbed-bit", I am referring to the
trunk supervision signalling protocol (on-hook/off-hook) status.
Every sixth frame, the least significant bit in each channel is used
to indicate the on-hook/off-hook status of the trunk.  This is used
for call setup and release in some applications.  In the US, most
calls probably will be using common channel signaling (CCS) and will
not steal that bit. Also for data calls, (ie. your application), the
robbed bit signaling should not be enabled.

The other place data is lost is the zero-code suppresion standard
being used.  There is a standard called B8ZS (binary 8-bit zero
substitution), which allows for no bit stealing to prevent long
strings of eight zeros.  An older standard, called zero code
suppression for lack of a better term, will corrupt one bit to prevent
a long stream of zeros.

The reason that a long stream of zeros must be prevented is that the
T1 carrier signal is a self-clocking signal, ie. the data carrier also
includes the timing.  This self clocking encoding doesn't work on the
zero bit encoding, but just on one's.  A long stream of zeros can
throw off the clocking of the receiver.

I can't help you with the in-house application without framing.  Good
luck on your quest.

I can explain this. WEFM was the first FM station in the country using
the current FM system. FM was invented by Armstrong and he won
approval to start broadcating in the 1930s. David Sarnoff (RCA) had a
VERY strong dislike for Armstrong (a former employee) and he put
intense pressure on the FCC to withdraw approval for the Armstrong
system. The FCC went along with RCA and approved an almost identical,
but incompatable system using the current FM band. While Armstrong
could have easily modified his transmitter for the new system, that
would have left all of the receivers sold by Armstrong Radio obsolete.

Sarnoff also formed a consortium of manufacturers (including Zenith)
who all refused to pay Armstrong any royalties for his FM patents.
Armstrong spent most of the rest of his life fighting Sarnoff and
deForrest over patents rights, went broke paying legal fees and
committed suicide.

This information is mostly from a recent PBS program on the pioneers
of radio.

Products like this exist for adapting a single-line phone to two
lines.  For example, I have an old J&R Music World catalog
(800-221-8180 or 718-417-3737) which lists an "Arista 241445 Two-Line
Console" for $19.95. The picture shows a small box with three buttons
and four LEDS.  The third button is for hold, presumably holds the
line currently not in use. Two leds per line, one red, one green, to
indicate active and hold, presumably.

Your fax users would have to remember to switch back to the incoming
line after finishing a transmission, or else they'd lose faxes.  So
it's somewhat accident-prone. I don't know if there is an automatically 
switching gadget like this.

I think the main reason that a 1 is prefixed first is because that was
the only way a mechanical switch knew to send you to a cama trunk and
there are still a lot of mechanical switches left.  When these were
changed to a digital switch, the dialing plan was left intact to not
cause confusion.

You dial it as a local 7-D number. The strange part is that you can
also dial 1-508-NXX-XXXX and get the same thing.  Oh ... the part I

Washington just switched to N0N/N1N exchanges.  

I can't say _for sure_ how it is implemented in the switching centers,
but the practical result is that you had better dial all ten digits on
every call.  Failure to do so has resulted in either a wrong number,
or a "sorry" message.

Get used to it, people.  Phone numbers have always been ten digits
long, we just got to take shortcuts.  Mostly due to truely stupid
equipment (remenber when you could dial another number in the same
exchange with only three or four digits?).  We just don't get anymore
free lunch.

Still working on _natural_ intelligence.

I am confused too.  Is this not clearly in violation of the alleged[1]

specific numbers where there is a repeated problem, but blocking 800
and calling card is not allowable.

Seriously, it's just another example of Hollywood's slavish devotion
to absolute accuracy.  I didn't see that part but I noticed something
else.  A District of Columbia police car takes a murder suspect in for
booking.  The back of the police cruiser rolls off, and we can see the
license number, a standard white DC license plate with blue lettering,
consisting of the letter "H" and four digits.

There are two things wrong with this picture.  First, in the District,
police cars have special all blue license plates with white lettering,
which say "POLICE DEPARTMENT" on them; they are not standard license
plates.

Second, the "H" series plates always have five digits after them.
They have to.  They're for taxicabs.

Why assert that conversations cannot easily be followed between cells?
It is not as if the mechanism for handoffs is secret; it is done in
band and someone with sufficient motivation should easily be able to
decode and interpret this information.  While its true that Joe Blow
with a scanner won't be able to, it is by no means difficult enough to
to give anyone a sense of security.

MISCO now has a unit that will do just that.  It is called the Ring

one of the four outputs determined by the incoming ring pattern.
