Part 2 introduces MPEG audio compression layers 1 through 3 and the
MPEG systems layer.

Day 1:

o Psychoacoustics.
o Quadrature mirror filters.
o MPEG audio layers I and II.
o MPEG audio layer III.

Day 2:

o MPEG audio bit stream syntax.

What equipment is required at each location?  What are the typical
startup and recurring charges for this level of service.

What other alternatives are available besides switched 56k service?

Several of the sites are in the greater San Francisco area.  What kind
of services and rates does PacBell offer?

I found the June, 1992 Jacksonville, Florida directory on Phonefiche
tonight.

It's official, that 1 + 904 + number is required within 904 area code
(northern Florida), even though that NPA is probably nowhere near
saturation with its NNX scheme. All of Florida must now dial 1+area
code within the area code, thus it looks like Southern Bell opted for
state-wide consistency in dialing, and changing things well in advance
of the interchangeable NPA system in North America by January, 1995.

Meanwhile, another note in the directory announces the start of a
semi-local dialing from Jacksonville to Hilliard at a cost of 25c/call
*flat rate*. This was effective 6 August 1992. Perhaps this
arrangement is the shape of local dialing to come.

As you indicated.  It's probably an 'IBX', manufactured by 'Intecom'
near Dallas, Texas.

False.	You've got your terminology backwards.
 
In the current (normal) environment, the 'Ring-Back' signal is
generated by the switch local to the called (ringing) telephphone, not
the caller's switch or CO. (Unless of course it is a local call within
the same system.)
 
On the Intecom IBX (and TELARI) systems, the ring-back audible signal
is controlled by matrix parameters in both the originating (trunk
group in this case) and terminating (station) 'Class of Service' (COS)
and 'User Group'.  There are (literally) pages of parameters that can
be altered to fit the needs of the system.  (Users or administrators
as the case may be.)  Maybe you want a 'Priority Ring' (a triple
[three short] ring)?  No problem.  It can even be altered to provide
no ring at all.
 
[Note: Kind of hard on the users though.  :-)	]
 
> We own our own switch here, but I don't know what kind it is.
 
See above.  It's probably an IBX.

PAT:

This is a classic:

Using a POTS line on a PBX:

PBX user calls some place and is put on hold.
PBX user gives up, hangs up and plcaes another call.
User does not hold switchook long enough to disconnect, unwittingly
 puts the music on hold 'on hold'.
PBX user calls you, gets your answering machine, hangs up.
The music on hold is 'transferred' to your machine.

Two machines are now locked on to each other.  If your answerphone is
VOX activated, kiss your tape goodbye.

Anyway, using that scheme (thinking you hung up when you really
didn't), you can imagine how strange stuff gets on your answerphone.

Recently my father-in-law was killed in his home.  Amongst the varied
horrors of dealing with this situation, a telecom question has cropped
up.

We are now collecting messages remotely from his answering machine in
San Antonio, Texas.  There are many messages which are the first few
words of a recordings announcing something like "This is a collect
call from the county jail. To accept this call  ..."
 
But the message doesn't say WHAT county the "county jail" is in.  We
can not actually answer the phone; it's a thousand miles away.  Is
there any way to find out where (or who) the calls are from?

Many thanks,

[Moderator's Note: Our thoughts are with you in your grief. If any of
those calls were actually answered by someone who accepted them, then
they will eventually show up on the phone bill and that will identify
the location of the correctional institution. Is there any way to have
the phone put on call forwarding so it will ring direct to your line?
If so, then you could answer the next such call personally. Under the
circumstances, telco would probably set up the forwarding for you in
the CO without someone having to go there to physically use the phone
to set it up.   PAT]

   I've also had calls (my machine limits them to 30 seconds) where
I'd be treated to several seconds of elevator music followed by
"Hello?  Hello?"  and end-of-message.  Someone told me that several
companies are using a gadget that basically calls you and says a
canned message like "Hello, this is the X corporation.  We'd like to
discuss something with you; please stay on the line and a
representative will be with you shortly.", then music, then somebody
appears on the line expecting a human.  Their initial message seems to
be shorter than my outgoing one, so I never hear that part.

   Gee, I hope I didn't miss my opportunity to call a $4/minute and
listen to a sped-up recording telling me I missed out on winning all
those amphetamines ...  :-)

Since arriving in Prague, Czechoslovakia, I have had to improvise many
times from previous habits while using the facilities of the Czech
Academy of Sciences.  Among them was routing Internet messages through
a different mailer than the one where it would normally be sent.  In
the case I described below, the message would have been sent through
SMTP at INTERBIT at the Universitaet Wien, but instead I addressed it
to City University of New York on BITNET.

As I learn more about telecommuications and the Internet, I wonder if
explanations I previously have made were correct, or if I had just
attributed a phenomenon to another cause.  If the explanation I gave
my friend was incorrect, could you set me onto the right course.
Thanks.
 
         ------------Original Message----------
 
You can select the computer path from which to route messages, if the
default link is not available.  From Marist, email messages normally
route through University of Connecticut (UCONNVM) or Yale (YALEVM).
However, you can specify a machine at another campus by writing the
destination node as userid, percent sign, node; and then write "at"
sign and the node whose mailer you want to use.  For example, if you
wanted to send a message through CUNY's machine rather than Yale's,
you would address the note as follows:
 
budd%cspgas11@cunyvm.bitnet (you would probably drop .bitnet)
 
By specifying cunyvm or maristb as the mailer of choice, it got me
around the problem with SMTP/INTERBIT at the University of Vienna.
You may want to try it sometime.  I may want to write to the TELECOM
forum to learn more why it works.
 
            ------------End Message---------
 
Let me know if there is a different explanation for this.
 
If readers are interested, I can write something on the calling cards
available in Prague for making long distance phone calls from local
booths.

Our office just moved, and with our new building, we got a new phone
system.  Well, it isn't exactly "new", but it is newer than the one we
had before.  It is an NEC Electra-16/48.
 
I am still new to all this PBX talk, and it is a bit of an annoyance
that I have yet to discover how to program and use this thing, let
alone any of it's capabilities.  We have one manual called
"INSTALLATION SERVICE MANUAL" which is rather cryptic. It assumes
that you know all the PBX lingo and what you are doing.  On top of all
that the local telco no longer supports this beast so we have to get
someone from a differnt company in to make any changes to the wiring
or programming. We develop software and hardware here, so this is all
right in line with the technical capabilites of myself and a few other
employees.
 
How do I do anything with this? Where can I find out more information?
Does anyone still manufacture options for this? (The manual is dated
1983).
 
All I have to do is learn, so where do I look first? Hopefully
comp.dcom.telecom is the place to start.

I hope you don't have or use a cellular phone.  To do so would be

It's a day or two ago now, but where I work here in San Diego, we
couldn't use AT&T either.  Most calls were blocked, both in and out.

Unfortunately, our phone consultant has yet to reprogram the company
switch to permit 10xxx dialing, so we couldn't even try other carriers.

We did get an AT&T operator who explained that "one of the other
carriers" was having a problem (likely cable cut) but that the Pacific
Bell office couldn't handle things.  Seems to me they should have been
able to.
