Happened to see _Shadow_of_a_Doubt_ (an Alfred Hitchcock classic) on
TV the other night.  In an early scene, the mother phones the
telegraph office to hear a telegram, and shouts her end of the
conversation.  Her younger daughter says "No need to yell" and
comments in an aside "Mother makes no allowence for science -- she
thinks she has to cover the entire distance with sheer lung power!"

Bell Canada went to court to seek "leave to appeal" the competition
decision handed down by the CRTC last month. The court ruled that the
appeal could proceed, possibly in the fall. Bell wants to change some
of the terms of the decision to allow long distance competitors access
to Bell's network, particularly the 70% share of the initial
interconnection costs that are to be borne by Bell, with only 30%
borne by competitors. Unitel claims that a delay of six months getting
to the marketplace would cost them about CAD$588 million. Bell Canada
and other existing Canadian telcos consider the CRTC decision to be
"expropriation" of Bell's assets without adequate compensation.

The decision requires Bell to allow for test facilities to be set up
for competitors, though the actual interconnection has to wait until
the appeal is finished.

The legal wrangling is no doubt part of the competitive process, as
are advertisements shot by one party and another. Unitel recently
placed an ad featuring two babies, one dialing a toy telephone with
the other bawling away at the idea of the other having the phone.
Unitel's ad quipped that it was not easy being the only child
(referring to Bell, et al) for so long, and touting the benefits of
competition.

Dropping of letters from telephone numbers varied from place to place.
In Wilmington, Delaware, the directory released in October 1966 was
the first there NOT to have the exchange names, although since about
1960(?)  some exchanges had been created which never had names (737 in
Newark, Del., for example).  POrter 2 & 4 (now 762 and 764) in
Wilmington had been created in 1957 (had to read this because I am too
young to remember it).

But the 1976 Philadelphia directory was still using exchange names.
As in the Wilmington case, these were the two letter + five number
type; the cases (cited in the Digest) of three letters and four
numbers are too far back for me to remember.

According to the 13 July 1992 issue of {Television Digest}, USA Video
wants to test a video-on-demand service this fall "using one of
Southwestern Bell's two fiber testbed communities outside Dallas."
The technology was tested in SW Bell's lab in St. Louis in June.  A
compressed movie can be delivered to the home in 3 1/2 minutes using
the "equivalent of less than ten standard video channels for rapid
delivery."

USA Video has a research operation in Dallas.  I'd like to learn more
about this venture including what SW Bell's "fiber testbed
communities" are.  In addition, I'd like to create a current list of
such projects nationally and will be glad to share the results with
comp.dcom.telecom readers.

Please feel free to send email directly to me.  The Dallas project is
of special personal interest as I may be able to take a sabbatical
there in 1993.

Thanks very much.

Effective July 22, 1992 phones in the western and the EASTERN part of
Germany are only be reachable using the country code 49. The full
cutover follows a transition period since April 15, 1992. The country
code 37 for the area of the former DDR (GDR) will not longer be valid.
All areas in the eastern part of Germany already use new area codes
starting with 3 for calls from West to East and for international
calls.  For calls within the eastern part of Germany the new area
codes will be introduced between July, 1992 and the end of 1993. This
will complete the reunification of the German phone network.
 
By the way, when would the country code 37 be available again (e.g.
for the new countries in Eastern Europe)? Is there a waiting period
before 'reuse' of a country code?

Clarifications for those interested:

X.PC is a Tymnet developed protocol that is like X.25 for dialup
terminals.  MCI does use X.PC to provide a reliable link.  One problem
with X.PC is that it does require 8 bit transparency which means it
can run into difficulties through some paths.  The newer MCI (9600bps)
lines support MNP5 for compression and error correction but the
reliability is only modem to modem and not end to end like X.PC,
though that might not be a problem because ...

MEP2 is a protocol for exchanging mail messages.  It is symmetric with
the two ends taking turns as master and slave.  The master presents an
envelope and then body parts (in the X.400 sense, not the medical
sense!) which can be binary or ASCII.  MEP2 encodes everything in
printable ASCII so that it can run over essentially any link.  It uses
simple checksums for error checking.  There is a retransmission
protocol to recover from errors but I've always felt hanging up and
retrying made a lot more sense.  Since MEP2 does error checking and
X.PC and MNP provide reliable links (end to end or modem to modem),
MEP2 rarely gets stressed.  Even without the lower level error
correction, many phone lines themselves are quite reliable.

One downside of MEP2 is that there is no header/envelope distinction
which means you can't separate the routing information from the header
and thus it is difficult to write a proper gateway between MCI and
other systems.

The new support for binary files in the INTERACTIVE sessions as well
as the encoding of attachments exchanged with the Internet does
strengthen MCI as a full mail service.  Note that the Internet
encoding is not really a function of MCI itself, but of the gateway
that translates between MEP2 and SMTP (I assume).

One advantage of MCI is that it does provide an email service for end
users with national (and some international) support.  Now, if they'd
only deal with headers ...

Disclaimer: Since I wrote much of Lotus Express, I'm not an entirely unbiased 
observer.

MultiTech Systems, Inc. (1-800-328-9717) makes an excellent hardware
dialback modem with 30-user password security which will call
different dialback numbers depending on the security code entered to
the modem.  Also to further thwart fraudulent attemps, the MultiTech
modems wait approximately 45 seconds before attempting the dialback
process.

With the MultiTech (I have several in use) there is no need for *any*
external security devices.

Steel wool is a bad idea, because pieces of it can come off and short
things out.  The pros often use a pencil eraser.  This is particularly
important if you're cleaning something like a switchhook contact.

He reversed one or more of his cells when he left the thing on after
the low battery light came on.  The best thing for the battery (but
not usually the most convenient for you) is to run the phone until the
'low' light comes on, then turn it off and completely recharge it.

During the recent incident in Tulsa in which a woman died of a heart
attack and her husband was unable to get through to 911 due to a
clogged phone system, there were a couple of facts which were not
totally clear from the news account.  While nobody actually came out
and said as much, I believe that people trying to call 911 did get a
dial-tone from their exchange.  The trouble occurred when they dialed.

The reporter gave an example of a busy signal, but it is not
known precisely whether the sound was recorded from an actual attempt
at dialing 911, that morning, or was simply a recording of a busy
signal used as an example of what one sounds like.  The thought even
occurs to me that the caller might have even heard a reorder signal
since many people call that a busy signal.  My idea of a system to
shed non-emergency calls in order to free circuits for 911 is based on
at least getting a dial-tone.  It is quite true that if there is no
dial-tone, the switch doesn't really know that you are there, yet.

Most of the exchanges in Tulsa are now electronic and it would seem
possible that they could be programmed to make room for 911 calls,
assuming that they, themselves, weren't so overloaded that they were
no longer capable of giving dial-tone.

In my opinion, the best way to

   reduce fraud
   keep AOSes from overcharging
   provide a convenient means for calling without leaving a paper trail

is to go to a stored value card as used by telco in most other places
around the world.  Of course, someone can manufacture counterfeit
cards, but it's more difficult to do than peer over someone's
shoulder.  Also, since it is a stored value card, other carriers would
have no incentive to honor the card (they won't get paid), so they
could try to vandalize the card or more likely just reject it. Thus,
protection from AOS overcharging.

Of course, certain federal agencies won't like number three, so
Congress will have to pass a law requiring that

  (1) each phone record its number and time of use on the card; and
  (2) that each buyer send in his/her used cards with proper identification.
      Failure to do so would result in a $10,000 fine per card.

Scramblers of course vary but a common technique is frequency
inversion, if we presume that the telepone bandwidth is 300 - 3300 Hz
(mainly because I'm lazy) then 300 Hz is translated 3300, 3300 to 300
and 1800 stays the same. The technique is to ssb usb modulate the
speech with e.g. 100 Khz giving us 100.3 to 103.3 KHz then ssb lsb
demodulate with 103.6 giving us 3300 to 300 Hz. I'm told that this
technique is only effective against casual listeners. Another
technique is to encode digitized speech, CDMA is an example though for
different reasons.  Needless to say that these techniques require
digital tarnsmission for reliability.

Tracing from the home is not strictly possible, in the USA there are
these newfangled caller ID devices. I have heard that NZ Telecom is
now controlled from the USA so perhaps you'll get them soon. Ericsson
market a facility in their AXE exchanges that allows the subscriber to
indicate that they have received a call that they want traced and a
printout is generated in the exchange. The effectiveness of this
technique depends to an extent upon where the caller calls from but it
is a very usefull facility. As it is exchange based however it is only
useful for official type tracing, not casual curiosity. I would guess
that most (if not all) exchange types have a similar facility.

Just in case your local Bell telephone repair guy isn't as much fun as
one I just worked with, I thought you might enjoy this little episode.

A company I'm associated (loosely) with has an office in an office
building.  Most of the building is owned by one company, which has a
large PBX for the building in the telephone closet.  The punchdown
block is above the PBX.

When this little company had a dedicated phone line brought in by Ohio
Bell, the installer came in with a six foot ladder.  Unfortunately,
that ladder was a little too big, thus putting him too far away from
the punchdown block.  So, instead of going back to the truck for a
shorter ladder, he figured he could manage ok if he could just find
somewhere to put his foot while he worked.  "Hmmm, top of the PBX
looks just about right -- I'll put my foot there ..."  Of course, as
soon as his whole weight shifted to the PBX it ripped free of the wall
and smashed to the concrete floor below ...

At this point Ohio Bell is into the company who owns the PBX for
$23,000 for repairs to the PBX.  It may go higher.  Ohio Bell, being a
fair minded company, wanted to just take it off the companies monthly
phone bill :-) For some reason the owner of the pbx didn't agree to
that arrangement :-O

I'd really love to have been a fly on the wall back at Ohio Bell when
the repair person came in to explain how that darn PBX just jumped off
the wall :-) :-) :-)

I was under the impression that the recent ruling specifically
addressed issues raised by Bellcore's recent announcement that they
could do 1.5megabit (i.e., MPEG) transmission over in-place twisted
pair copper loops.

Then again, I suppose that if the cheap experiment possible because of
the aforementioned technology proves successful and profitable, TPC
fiber-stringing crews would rapidly become common sights on
neighborhood streets.

I think that personally I hate cable companies more than phone
companies, so I'm pleased by the ruling.  I suspect that if John were
in a situation to require service from his cable company comparable to
what he needs for his telephonic endeavors, he would see that by
comparison GTE be a glittering paragon of virtue.
