How does caller-ID work?

My understanding thus far is that when I call someone with caller-ID,
she/he can recognize my phone number. How is this achieved?

Isn't there a service provided by the phone company that does the
same?




Please shed some light...

Not really true.  The outfit that now controls the telephone
system in Moscow (Minsviaz) was quoted about certification and a
'modem hunt' in a Commersant article some months ago, but like so
many things in Russia very little has come of it.

There are a great many modems in use throughout the CIS, and I
have heard of no cases of problems from the authorities.

Phone rates are being increased, and the phone system is
unreliable and noisy.  But plain vanilla 2400 bps MNP modems work
well in the CIS.

This is not true in my experience.

Agreed, but the bureaucrats have not done anything yet.  They are
perhaps aware of the vital importance of Email and FAX to
cooperation between US and Russian businesses, something they
want to encourage.

Subject: More Advice Regarding BFJ
Organization: McMaster University, Hamilton, Ontario, Canada.
Date: Thu, 27 Aug 1992 03:49:51 GMT



I believe I have some more worthwhile information to offer on BFJ and
how people who have merchandise on order from them (quite possibly a 
*prepaid* for Supra modem, such as I have) should proceed. 

First, I still can offer no "proof" one way or another that BFJ has 
closed its doors permanently, but in response to my repeated inquiries I
have received additional corroboration that the store is currently shut
with a "Remodeling, open in two weeks" sign on the door, even though they've
been closed for well over two weeks and (I'm told) no visible remodeling is
occurring.  From the E-mail I've received (some forwarded through a third
person from a former BFJ employee) it seems *likely* (again, I have no
direct proof) that BFJ will not reopen, except possibly to liquidate
inventory.  

The *good* news is that I've spoken at length to the Atlanta area Better 
Business Bureau and they were quite responsive.  According to the fellow
I spoke to, if you have paid for merchandise undelivered from BFJ they will
make every effort to see to it that BFJ honors its commitments.  To get this 
to happen you must file a complaint against BFJ.  To do this, call the 
Atlanta area BBB, 

BBB phone # is 404 688 4910

and wend your way through the #$^@*&%^# automated phone menu thingy (who the
hell invented those things) by selecting the option "file a complaint on a 
local company" (i.e. hit #3) and talking to the people there. I was warned
that if the owner chooses to just "close his doors and walk away" there was
little the BBB could do --- BFJ is a BBB member, and apparently the owner
will have trouble reopening or liquidating if they are processing our
claims --- but, *if* you prepaid with a credit card there is usually a
"good faith" clause in your card agreement.  If you make a "good faith"
effort to recover your $ or your merchandise from the vendor, and you
fail, then the card company will usually cover your payment.  Obviously, 
filing a compaint of this sort goes a long way towards satisfying the 
good faith requirement.  

Thus, I *strongly* urge any of you in the situation I'm in to contact
the Atlanta BBB and file a complaint against BFJ.  (It may even be that the
force of our numbers will garner our case additional attention).

Hope this is helpful ---- Tom

To open a Supra external modem, you need to remove the two screws on
the bottom, and then remove one of the plastic end caps.  You will
probably also have to unscrew the power switch handle on the front
panel.  Once you remove one of the end caps, it becomes very easy to
just slide the PC board out of the case.  Be careful with the V.32bis
FAXmodem, since it has components surface-mounted on both sides of the
PC board.  Also be careful that you correctly reassemble it; this
modem has a voltage regulator on the bottom of the PC board that gets
*very* hot.  That chip has a small heatsink on it, which is supposed
to contact the metal case and thus heatsink the chip to the case.  If
you do not reassemble the modem with the voltage regulator's heatsink
touching the inside of the case, it will probably get too hot and blow
up after operating for a few hours.

However, you don't need to open the modem to determine the ROM
revision.  Just use the ATI3 command.

I, too, have had some problems with 14400FXSA Zmodem xfers... but I've
found that when I'm not using MNP5, things run smoothly (this is on a
2400 connection)... in fact, I can get around 3100 chars/sec on a 14400
connection with compression/correction.  Maybe the problem has to do
with the additional compression of MNP5?
All in all, I'm quite pleased with my 14400FXSA.

Suggestions or solutions welcome, as I'd like to not have to disable
MNP5 for these connections.

Actually, that's not been my experience at all, unless I'm reading you
incorrectly.  I bought my first one from a distributor (or at least my 
employer did) - the three RMA units replacing it came directly from 
Supra.  They didn't say anything to me about original packing, either.

Actually, V.42bis says nothing about what result codes might be 
issued.  Whether a particular modem will issue a "COMPRESSION: 
V42BIS" (or whatever) result code just because the V.42bis-related 
parameters existed in the XID (negotiation) frame, even though the 
result of the negotiation was that compression was turned off in 
both directions, is up to that manufacturer.  I dare say it would be 
pretty silly to do so.

There is no standardized benchmarks for comparing performance of 
V.42bis modems at this time. However, TIA TR-30.3 is currently 
developing a TIA Telecommunications Systems Bulletin (TSB 38) which 
will provide "application notes" on modem testing methodology. 
Although I haven't personally been involved in the work on this TSB 
(another Hayes systems engineer has been representing us in that 
activity), it is my understanding that it will include both 
recommended testing procedures and test files for V.42bis 
compression.

Leaving it to work with BYE is, of course, out of the question.  I know

The same way Blackbox Inc. does:  By emulating a terminal (Ususally a 3101) in
what they call "a protocol converter".  The box then expects to talk to one of
several terminal types via RS232C.

Another possibility is TN3270, a 3270 emulator expecting a telnet like connection
to the IBM, which then goes into 3270 "mode".  This implies an ethernet port
on your IBM and appropriate software.
