I am a little late in seeing this thread, but there is another
solution.  The modems can be set up as reverse-carrier which means
that it is the calling modem that "shreeks" and the receiving modem is
silent.  This is the way that FAX/MODEM switches work where you can
share a single line between a Fax Machine, a modem, and a answering
machine.  Unfortunatly, both the sending and receiving modems need to
be set up as reverse-carrier so you cannot use this for a
bulletin-board type of setup since the callers will have to use a
non-standard setup inorder to access your dial-in line.

This is in reply to Mark Kelly's question about overflowing from one
DN to another.

It depends on the technology supporting your T1. If it is sitting on
some
advanced switch like a DMS (advanced in relation to electro-
mechanical), a
simple 'replace tuple' after the overflowing trunk group and then send
the switch back to it's digit analysis tables will do the trick. This
set up will work with a few of the MITEL and GEC PBX's out there also.
If it's anything older than a DMS, a second trunk group appears to be
your only choice.

Applying some social engineering, the ANI of the 911 business office
would probably be a good flag for special subscriber numbers that
don't return a true ANI, like cellular numbers.

After all, how often do you think their own business office calls 911?

As I recall, Distinctive ringing is (was) called Multiple Directory
Numbers per Line with Distinctive Ringing - MDNL/DR in the AT&T 5ESS
Switch documentation. This may help someone researching this.  (I used
to be a 5ESS switch tech in an AT&T Digital CO).

As I recall, this was also used as a method to return coins at a coin
telephone when calling a (then) "free" nomber such as 411, "0"
operator,
and the telephone company business office. My mom used to be the cord-
board (!) operator at the local Ma Bell business office, and I would
call her at work and get my dime (later quarter) back when the local
CO would reverse the current momentarily. Ah, memories!

Subject: Re: Horrible Eartquake in Japan


Yes, it was an eartquake of quite some magnitude, but you have got a
few figures a little wrong.

The last count I saw with the number of dead poeple were around 1500,
so if you skip a zero in your "170,000 people have died" then it looks
more realistic. It will probably go over 2000 when they have finished
their clean up.

I don't know if it is the worst quake in over a hundred years in
Japan, but maybe in the area called Kansai in Japan (with Kyoto, Osaka
and Kobe). I think the earthquake in Tokyo in 1923 are considered to
be worse (I don't remember the figures) and then many thousans died,
not so much because of bulidings crashing, but more because of the
burning down of the (woodden) houses.

I don't live in the area, but 500km away from it, however even here
they were able to measure it. All TV stations only had one program
yesterday: The Earthquake. I think the quake is comparable to the one
in Los Angeles some time ago, but I think also this time the burning
down of buildings will be bad, because of the little (and expensive)
space, they are built very close.

That is all I have, but somebody living closer might have more
details?


Peter Rasmussen


[TELECOM Digest Editor's Note: Regards the increasing death count, on
the television news tonight it was over 1800.  Having the buildings as
close together as they are does not help, and as you point out it
makes
the fires even worse. A couple months ago here in Chicago we had an
entire city block burn down. About a dozen buildings were involved
which are built very close together (just perhaps five feet of space
between each of them) combined with extremely strong winds. As the
burning
embers flew through the air they landed on rooftops up and down that
block; a couple buildings on the other side of the street also caught
fire as a result.   PAT]

Don -- well, let me tell you what ATT did to us here in the Chicago
market.  They began offering service (accessed by 10288) for longer
intra-lata calls (over eight miles, which are timed calls here, less
than
eight being untimed).  They advertised the hell out of it -- cheaper
than
Ameritech (formerly Illinois Bell), they advertised.  And it was.  15-
mile
calls were (these are from memory but fairly accurate) around 1 to 1.5
cents/minute, vs Ameritech at 1.5 to 2.0 cents (depending on day and
time).

Then, three months later (December) the rates changed.  No ads, no
announcements. Seven cents/minute now -- roughly three times the
Ameritech
rates.  It turns out the low rates were "temporary, introductory
rates."

Talk about bait and switch.  This is hook and switch!  A fair number
of businesses had programmed their systems to automatically add the
10288 dial string.  And they didn't find out about the change, often,
till the new bills were processed, perhaps after six to eight weeks of

·
paying higher rates.

So, if you switch to ATT for local service, watch what they do to you.

OTOH, we still go ATT for interstate long distance.


/bob/


[TELECOM Digest Editor's Note: Even though AT&T did not advertise
their
increase in rates, Illinois Bell made sure to let everyone know about
the changes. Did you see the ads run by Ameritech (IBT) saying 'AT&T
has such a deal for you!  They want you to pay 81 percent more for you
local calls than we do ...'  The ad went on to explain how the AT&T
rates had increased after the short 'introductory' period.   PAT]

What LDDS is saying is that they don't have SS7 signaling in your area
for data calls. Where are you going to be calling with your ISDN line?

IMHO, you're better off with either AT&T or MCI for overall deployment

They are not the same.  GIF uses LZW, patented by Unisys; JPEG uses
arithmetic coding, patented by IBM.  But JPEG also allows Huffman
coding which is used by most generally available JPEG software.  (BTW,
actually LZW is also patented by IBM to make it more confusing.)
