On August 8-11, 1995, UCLA Extension will present the short course,
"Multimedia Compression: Principles, Applications, and Standards", on
the UCLA campus in Los Angeles.

The instructors are Jerry D. Gibson, PhD, Professor, Department of
Electrical Engineering, Texas A&M University; Richard L. Baker, PhD,
Chief Scientist, PictureTel Corp; Toby Berger, PhD, Professor, School
of Electrical Engineering, Cornell University; and Tom Lookabaugh, PhD,
Vice President, Research and Business Development, DiviCom.

The efficient digital representation or compression of data, speech,
music, facsimile, still images, and video for storage and transmission
plays a dominant role in current and developing communications
systems, computer networks, PCs/workstations, video-on-demand, and
entertainment.  Standards have been and continue to be developed for
this host of multimedia applications that will serve as the traffic on
the information superhighway.

This course explains the fundamental principles and algorithms
underlying these standards and describes in detail current and
evolving multimedia compression standards.  Audio tapes, slides,
videotapes, and equipment demonstrations complement the lectures.  The
course should helpprofessionals to understand existing standards and
products, evaluate future standards, and incorporate these compression
methods into their ownapplications.

Topics include: entropy and lossless coding, quantization, predictive
coding, speech coding standards, frequency domain coding, audio
coding, vision, perception and image representation, standards and
applications in video compression, grey-scale image compression,
videoconferencing, desktop videoconferencing and collaboration.

The course fee is $1395, which includes extensive course materials.

On August 2-4, 1995, UCLA Extension will present the short course,
"Transmission of Multimedia Information and Data", on the UCLA campus
in Los Angeles.

The instructors are Chris Heegard, PhD, Professor, Electrical
Engineering Department, Cornell University, Ithaca, and Andrew J.
King, MSEE, Design Group Manager, Communications Products, General
Instrument Corp, San Diego.

Each participant receives a manual used by DigComT, "The Digital
Communications Toolbox" and extensive lecture notes.

Digital communication systems are used for the transmission and
storage of a large variety of data, speech, still images, audio, and
video information for a wide range of applications including
facsimile, telephony, voice mail, digital cellular mobile radio,
CD-quality audio, personal communication systems, video-conferencing,
video-on-demand, and HDTV.  The physical transmission media for these
applications, called channels, take a variety of forms such as copper
wire pairs, coax cable, optical fibers, electromagnetic radiation,
magnetic tape and disks, and optical disks.

This short course presents the basic digital transmission methods for
conveying digital information through these channels efficiently and
reliably and covers the fundamental techniques for digital transmission
 from first principles to applications and implementations.

The course presents an overview of the how and why of modern reliable
data transmission.  In multi-media applications, compressed information
must be reliably delivered over channels that exhibit real-world
limitations
such as noise, distortion and interference.

The course begins with an introduction to the basics of digital
modulation theory and channel capacity.  The results of this
discussion are then used to motivate the need for Forward Error
Correction (FEC) systems.  An overview of the engineering methods that
have evolved for these applications follows, including basic
modulation methods, techniques for FEC, algorithms for tracking
channel parameters and ideas for adaptive receiver design.  Both
hand-workable examples and a computer are used for developing a basic
understanding of modern digital transmission systems. Such ideas as
block, convolutional trellis and concatenated coding are described, as
are methods of signal tracking and adaptive receiver design.  The
course provides practical methods for implementing digital
communications systems, and a summary of some basic standards are
presented.  This material covers all issues concerning the development
and prototyping of digital systems, with particular emphasis on
communications applications, computer analysis and simulation, and the
basis of modern VLSI design methodology.

The course fee is $1295, which includes course materials.

Quebec-Telephone, the second-largest telephone company in Quebec (Bell
Canada is the largest), has opened a WWW server at:

http://quetel.qc.ca/qt0000ag.htm

Other WWW servers operated by Canadian telecommunications companies
include:

http://www.bell.ca        Bell Canada

http://www.bctel.com/ (BC Tel, formerly the British Columbia Telephone
Company)

http://www.sasknet.sk.ca/Pages/sktlhome.html (SaskTel)

http://www.rogers.com Rogers Communications, a cable TV company which
owns part of Unitel and has others communications and media investments,
including Rogers Network Services.

http://www.stentor.ca      Stentor, the consortium of telephone
companies

Interestingly, while Quebec-Telephone and BC Tel are both partly owned
by GTE Corporation, GTE has not yet set up a WWW server of its own.
(Its GTE Laboratories unit does have one at http://info.gte.com,
though.)

Our company is undergoing a feasability study on manufacturing of
basic analogue telephones for the French telecom service. As most of
our experience is with providing terminals with small digital switches
for British Telecom, Deutsche Telekom, and the Dutch PTT there are a
few questions that are posing slight difficulties with regard to
testing. The documentation which we have is one user guide (all in
French of course :) ). These are not insurmountable, but if anyone
knows the answers it would simplify matters. The name of the telephone
is AMARYS "210".

1. What are Ringing frequencies, as well as DTMF frequencies/amplitudes?

2. What exchanges does this telephone connect to  (PBXs' etc..)?

3. Are there any features of these exchanges that operate on this
telephone
   (eg. CLI etc..)?

4. What type of barring is available on French exchange systems
   (eg.Line-to-Line)?

5. Are there any 'funny' French quality specifications (like the
equivalent of

   BABT) that would involve us for example carrying out 'drop' testing,
or
   lightning tests etc..?

If anyone can help us out, it would be much appreciated. Thanks in
advance.

MY PROBLEM:

 I have a medical problem, with my ears, whereby I have
required the use of an amplified telephone "handset or headset" for
years.

 I have been in telemarketing, "Screaming into the telephone"
for years, which has caused my hearing to get progressively worse.

I NEED:

a. I need to eliminate or 'lower' the sidetone in my handset.

b. alternately, since I normally work in a private office, so, I could
talk into a handset microphone and use "external speakers" to 'receive'.

I am new to the Internet and don't know where to look for this answer.
I have, for five years been speaking to Engineers at Bell labs, NY Tel,
most of the telephone suppliers, most of the handset and headset
suppliers,
with almost no success (with very few people even understanding the
term 'sidetone'.

The only possible help I found is in the book "UNDERSTANDING TELEPHONE
ELECTRONICS",  which is 'Greek' to me. (I can E-mail the discussion if
requested)

If you can help with the solution or lead me to some avenues of possible
assistance I will be in your debt.

Yesterday, I received a call from a friend in the US and was very
surprised
to find his phone number on the phone's display even though I'm in
Germany.
I must admit that I have ISDN (Caller-ID is not provided to analog lines
in
Germany at all.)

My friend called from the 301 NPA and was using AT&T for long distance.

Some time ago, I received a call from area code 617 and the Caller-ID
did not show up, just "Number unknown". I am not sure if that person
used AT&T or some other LD carrier.

My question is: What long distance companies pass caller-ID along on
international calls? Also, did readers in the US with Caller-ID receive
international numbers on their Caller-ID boxes?

I read a posting a while back about the FCC delaying the national
rollout of Caller ID.  Has a new date for this blessed event been
announced yet?

Hi,

I'm a third-year communication student at the Free University of
Brussels
(VUB), Belgium. I have to write a paper about the French Minitel-system
and the possible impact of this French succes-story on the "infohighway
policy" of the European Community because this EC-policy is rather
confused at the moment. So if someone out there could help me by mailing
me some information on this topic it would help me a lot.

Thank you in advance for your help and best greetings from Brussels.

Has anyone been able to use a PC based autodial program (such as
Windows Cardfile, or Metz Phones) in an office environment?

I have a separate modem line going to my PC, and the software dials
out OK -- I can hear the ringing and the answer over the modem
speaker.  I got our telecommunications support people to add my modem
line to an available button on my phone (NT Meridian M2317); but I am
unable to pick up on the line once the modem goes off hook, apparently
due to a feature called "privacy release".  Our telecom people have
been unable to figure out a way to remove the privacy release from the
modem line, which would enable me to pick up the call being autodialed.

Comments I've noted from our telecom people (which mean nothing to
me, but may help all of you ;{>} ) include:  "modem line is an analog
line and privacy release is incompatible with an analog line", "switch
is an SL100", "regular phone line is a digital line and modem can't
dial out on a digital line", "autodial software needs to send a
750ms break followed by *87 after dialing" (there's no obvious way
in the software to do that ...)

Any suggestions would be appreciated.  Request you respond to me
directly so as not to add to the overworked condition of our dear
Telecom Digest Editor.  If a working solution is found, I will
send a report to the list.

Thanks for your help!

The comparative market ranking I posted last month for the PCS Blocks A
and B auction were (How shall I put this?) ... well ... quite frankly
...
not even close.  It was a botched intermediate effort that mistakenly
got
included in my final output. Sorry about that! Set forth below is the
revised/corrected listing.

The process for compiling this listing was as follows.  The amounts bid
in
each market for both licenses (Block A and Block B) were totalled and
the
sum was then divided by double the MTA population. (This renders the
mean
avearage of $/Pop value of the two licenses in each market.) The
exceptions are the pioneers preference markets.  Only one license was
auctioned in MTA 1 (New York), MTA 2 (Los Angeles-San Diego) and MTA 10
(Washington- Baltimore), the other license having already been issued
pursuant to pioneers preference awards.  So only one bid amount was used
and the populaton was not doubled. However, a second calculation was
performed for each of these marekts for which the amount to be paid by
the
pioneers preference licensee (pursuant to the forulas specified in the
GATT legislation) was also factored in as if it were a bid on the second
license. Thus, for the "*" lines below, "w/o pp" = without factoring in
the pioneers preference licnsees, and "w/ pp" = including the pioneers
preference licensees.

Issue 212 of the current volume left here Wednesday evening correctly
numbered at the start of the issue, however the very bottom line
which is used by some systems for bursting and separation of messages
incorrectly identifified it as issue 213. Please correct that reference
on your copy. What you are reading now is issue 213.  Thank you.
