I just received this from a friend in L.A. who is also involved in
telecom.
                     -----------------

What a way to start the day.  I'm listening to KFWB and they advise
that Pacific Bell has had a major fire in the Downtown L.A. central
office.  Most of the 9-1-1 traffic from the San Fernandoi valley is
failed along with a lot of the long distance carrier access.
Apparently the fire started in a bettery charger on the 13th floor.
More details as I get them ...

Date: 15 Mar 1994 06:08:01 GMT
Organization: University of California, Berkeley


Hello,

I am a UC Berkeley student working on a digital design project
(a security system with dialing function).  We need a component that
receives the phone number (thru a 4-bit wire, in some binary coding)
and dials the number.  It then invoke a voice chip to play the
recorded message.

This component should be smart enough to tell whether the line
is connected or busy, and, possibly, whether an answering machine is
answering on the other end or not (of course we don't want the
secuirty system to leave a message saying that the house has been
robbed!).

I know there must be some chips of this kind on the market,
but I just couldn't find any good resource. Could somebody please help
me out?  Where can I buy this kind of chip and what will be a good
resource for finding them?  Hope that the price for the chip will not
be too high. (We are poor Berkeley students :)

We only have one month for this project ... please help!!!

Thanx in advance!

Subject: Telex Country Codes?

I'm confused over the assignment of Country Codes for Telex. I've been
told that the CC for Albania is 604 and that one of the CCs used by
INMARSAT is 581 but when I look in the AT&T directory of Telex and
EasyLink addresses, it says Albania is 866 and INMARSAT Telexes are in
the range 70X, 80X, 90X (where X = 2,3,4,5,6...).

Does anyone have any information about the assignment of these Country
Codes? Are they unique or do they depend on the country from which one
sends the Telex? I have not seen this sort of confusion over telephone
Country Codes.

I have heard of a company that presumably offers calls to Finland at
about $0.45 per minute.  That does not sound unreasonable to me as one
can call Germany for way less than that.

Thanks a lot for any help you can give me.

[TELECOM Digest Editor's Note: If you are getting international calls
between the USA and Europe for 45 cents per minute you are not getting
a bad deal at all. I cannot imagine calling Germany from the USA for
'way less' than 45 cents per minute.   PAT]

Dear Mr. J. B. C.,

Thanks for your fax of the 4th March 94 and the contents therein.  I
want to thank your prompt response to my request and I wish to state
and clearify you as thus:

I am Mr. Ola Benson, an Accountant with the Nigerian National
Petroleum Corporation (NNPC) in a contract award departement.  This
corporation is responsible for the oil lifting, Sales, Maintenance,
Repairs, Construction of oil rig and Installation of oil mining
equipments among other things for my country.  Your company address
was made available to me by an import agent who does extensive
business with my country but my contracting you was not made known to
him.

Now the transaction which made me to contact you is very much intact
due to its confidential nature for the interest of highly placed
government officials that are involved.

The project is that in 1991, we in the contract department awarded
through the governmen contracts to foreigh contractors during which
time we over-invoiced the contracts for our own personal use.  The
contract has since been completed and the actual contract value paid
to the original contractor. Based on our previous deal with the
contractors, we now want to purport your company as a subsidiary
company to the original contractor a provision which we created
wheroper understanding of the project before embarking on it.

Revert back to me for your comments and for us to know what is your
decision.

I await for your confirmation fax.

With best regards,

(signed)

OLA BENSON

Subject: Re: Video Conference Bridges


All major codec manufacturers (i.e. CLI, PictureTel, VTel, GPT)
manufacture or OEM video conference bridges, which are actually
referred to as "multipoint control units" or MCUs.  Each has benefits
and disadvantages.  Probably the most important issue for you wouldbe
compatibility with the codecs you are now using.  Although there are
standards evolving in this area, some MCUs are not comaptible with
some codecs, particularly those using proprietary algorithms and not
the H.261 standard.

 If you do not currently have any video conferencing codecs, then you
can make the whole package decision based on price, features, etc.

 Incidentally MCUs are generally above $50K in price. If you are not
expecting to do a lot of multipoint videoconferencing, you might
consider using a public network for your multipoint calls. ATT's
Accunet Reserve and Sprint's Meeting CHannel, for example, each have
the capability to hook multiple sites into a multipoint conference.
You pay for the time used and a surcharge for the MCU.

I didn't see any mention of caller name services so I suppose this
isn't covered by the new FCC regulation.

What is the position of the LECs with regard to LECs in other parts of
the country doing data base lookups on their subscribers?  Are the
LECs going to provide this info on a reciprocal basis or does this
still have to be worked out?

They do indeed.  In fact, on every carrier that I've had service from,
they will always return a recording in the event that the 10xxx code
was dialed but cannot be used (either because of no intra-lata
competition, or because it was dialed for an 800 or 900 number).  I
just checked this on a US West line, and upon dialing 10xxx-1-800-xxx-xxxx,
it returns the following recording.  "*SIT* Your call cannot be
completed using the access code you dialed.  Please check the number
and dial again, or contact your long distance company for assistance."

My information doesn't agree with yours Pat.  A friend of mine was
recently stopped for speeding and detained because she had a overdue
ticket for driving without registration, something she should be
punished for but not a particularly horrible crime.  She was told that
she was being detained until she could either pay the overdue ticket
or see a judge, and she was not being arrested; actually she told me
that on the whole she was treated very well.  There was a problem with
the phones however.  She was put into a holding cell, the cell did
contain a a standard Pacific*Bell payphone and she had a number of
quarters on her to make phone calls.  However she did not have her
phone book and needed to call information, the call would not complete
and when she called an operator she was told that they weren't allowed
to call information from a jail phone.  I can understand that they may
want to avoid newly arrested people from calling information to get
victims numbers and then threatening them from behind bars, but those
people are legally innocent, and in this case my friend was not
legally under arrest.

After she managed to convince one of the officers to loan her a phone
book (as I said for the most part she was treated well) she tried to
call a number of people to bring down the couple of hundred dollars
required to get her out.  She had trouble contacting anything more
than answering machines and quickly ran out of change, that's when she
found her calling card wasn't accepted and she was not allowed to do
third number billing, she eventually had to call collect (at very high
rates).  All things considered the phone problems extended her
detainment for two to three hours, not very pleasant or fair in my
opinion.

Subject: Decoding the Zipped ISDN File


Pat

I downloaded the file and took a look at it.  The file has been
uuencoded and you need to run it through a decoder, which comes in
versions for almost any computer connected to the Internet.  After
running the file through the decoder you get the zipped file and
PKUNZIP works just fine.
