Announcing the First meeting of The Chicago Area Internet Society: CAIS.

What CAIS is:

The Chicago Area Internet Society (CAIS) is a new organization formed to
help people who are interested in the Internet as a communications tool.
Our goal is to help professional communicators find out how they can

about how to get on the internet.

Future Goals:

CAIS will be holding meetings to get input from people interested in
helping form the future of CAIS.  Some plans for the future: monthly
meetings on HOT topics, developing a virtual organization on the
internet, ie: a WWW page for information with links to members home
pages, a news group and mail list and?  Your suggestions are welcome!

Hi everyone,

I know I posted a similar posting some time ago, but I did not get the
total, world-wide NUMBERS that I was looking for, although I'd like to
thank the people who sent the lists of operators.  So could someone
please give me a pointer/source to recent statistics on international
GSM usage?  I don't know where I got the information, but I think it
is 5.4 million subscribers.


Thanks in advance,

Is it just me?

I've been following these NPA changes and it seems almost every split
or overlay has some group of people really torqued off at the "big,
evil telephone company".

We hear the same tiresome argument.  "We don't want *OUR* children (as
if its society's collective responsiblity to rear them) to have to
memorize a ten-digit telephone number.", implying millions of children
will somehow die by having a ten-digital phone number.  If that were
the case, think of how many children die because of seven-digital
numbers.  Let's shorten them to five.

A shining example is the 404/770 split in Georgia.  By avoiding an
overlay, we prevented people from having to dial ten-digits, right?
Wrong.  There's a lot of cross-Perimeter dialing, meaning callers will
have to dial not just ten, but *ELEVEN* digits.  And look at the case
of our precious, helpless children.  Billy is lost at Perimeter Mall.
He finds a mall security guard who offers to call Billy's home.  Billy
knows his number is 555-9876, but can't remember his area code.  Well,
Billy could conceivably live in 404 or 770, who's to know?

I know there are far worse things in the world to get upset at, but
state regulators are really making a royal mess of our phone system.
Had the Georgia PSC allowed Southern Bell to do the 404/706 split
right, we wouldn't have this problem today.  I just hope in the
future, regulators look at Chicago, Atlanta, South Florida, and L.A.
and learn not to micromanage private industry who knows how to do the
job best.

[TELECOM Digest Editor's Note: I am told by some very old-time people
who were with the Bell System and are since scattered all over the
various Baby Bells today that if it were possible to set the clock back
a half century and plan things over again, that many changes would be
made. There were lots of very far-sighted well meaning people involved
during the 1940's and 1950's with planning for future expansion of such
things as area codes and local numbering schemes, etc ... but the
general
consensus today -- of the few who are still alive and that I have
chatted
with at one time or another -- that *no one* could have begun to
anticipate
the growth. There were plans even fifty years ago by some at Bell for
eight digit local numbers and *four* digit area codes; the majority of
the people involved thought such schemes to be outlandish and the
majority
involved in the process of planning 'area codes for the future' did
pretty
much correctly guess the time the old numbering system would be
exhausted;
what perhaps they failed to understand would be the social ramifications
involved in the new system.   PAT]

I recently did some work investigating CDPD.  One observation I made
was that CDPD is an excellent way to gain redundancy.  In most areas
(most populated areas?), there are two cellular carriers.  Since the
last mile is what is at greatest risk, half of any circuit is
protected 100%.

My question is about the other half.  Does anyone know if there is an
easy way to, for example, have a router connection to both the A-side
carrier and to the B-side carrier?  Then, you'd have almost perfect
reduncancy.

I would hope that you could just register the same Subscriber Identity
Module (SIM) with each carrier, much they way you might register a
single portable PC bootp servers on two networks.  (Is that a violation
of bootp?)  What I am not clear about is, where the IP address is
looked up.  Does the CDPD Mobile End Station know its own IP address?
I would think it WOULD NOT need to know it, because the Data Service
Manager would do that.

If this is the case, the device would just have two IP addresses, one
on each network.  My company's routers would need to be configured to
rout via whichever path is available.


Thanks

Seth

------------------------------



Does anyone know of any IP software that would be able to "tunnel"
(wrap up) IP packets so they can be directed to a far-away lan with a
variable IP gateway?  We need to "readdress" IP packets with a
different destination and then unwrap them at the far end.

Do you know of any sofware that would do that?  Both end machines are
Linux machines.  For a short period of time each day, we'd like to
link our lans (in different states) via dialup with the Internet.


Thanks!

I am looking for someone that has a working E1 interface using the
DS2153. Does it work right? Any bugs I should watch for? Any appnotes?

OK.  I can deal with that. Then pagers and perhaps cellular works the
same way with a bunch of trunks?  :-).  Then if said hospital only has
40 trunks (assuming trunks are what the rest of us call 'lines') then
only 40 of the 1000 extensions may be connected to outside calls at
one time which would explain why I've been in the hodpital and hit 9
and gotten PBX reorder type things.  Insufficent trunks to complete my
request, right?

GTE mobilnet has a bunch of "reserved" numbers in our area.  216-801
thru 805 are their's from 0000 to 9999.  Cellular One only has three
complete "reserved" exchanges.  Not much competition. :-).  Plus
there are four or five other complete prefixes given to GTE Mobilnet
here. :-).  They own the Akron Cellular market.  Except for one strange
prefix given to something I've never heard of (independant cellular).

Well, you're almost right.  The CPUC insisted that per-line-blocking
be available (I don't remember if it was to be free or fee.)  GTE and
PacBell said "forget it" and that's why California has no Caller-ID.

[TELECOM Digest Editor's Note: But the latest word is that California
will be having Caller-ID real soon now. In an issue of the Digest I
will send out later today, Lauren Weinstein writes to the Digest with
some recent developments.    PAT]

I had a similar and scary experience with AT&T USADirect.

I was calling from Switzerland to the US via USADirect for an airline
reservation.  The airline answered immediately with an automated
response system which would forward to a "ringing" phone after making
the appropriate selection.  After a few rings, I would be prompted by
USADirect to leave a message for later delivery.  I called the
USADirect operator and asked to put me through without this "service",
but the same "service" kicked in during my call.  In fustration, I
swore out loud about how stupid this was, when I heard...

"AT&T Operator, let me put you through again...."

I didn't know he had stayed on the line with me. :-(

As I remember it, I was able to use USADirect on other occassions and
allow the line to keep ringing.  I was just surprised the service
worked even after the initial call had been completed.

[TELECOM Digest Editor's Note: 'Accidents' will happen!  <grin>. For how
long have telephone operators been abused?  ... oh, since the dreadful
instrument was first invented, I suppose.  I have a microfilm copy of
the
1919-1920 alphabetical directory of the Chicago Telephone Company, which
was the predecessor to Illinois Bell until about seventy years ago when
AT&T bought out CTC about 1924 and renamed the company to be part of
the Bell System.  From the inside front cover in small, yet quite
readable
type, a notice entitled 'Admonishment to Subscribers':

           "Subscribers are admonished to refrain from cursing
           our operators or using foul and profane language in
           their requests for telephone connections. Subscribers
           are requested to address our operators in a courteous
           manner; the operators have been instructed to respond
           in a similar way. Would you want the operator to curse
           you when a connection was impossible because the called
           line was engaged or out-of-order conditions prevailed?
           Speak to our operators in the same way you wish to be
           spoken to.   Thank you."

Remember, in those early years of this century, telephone connections
were established entirely manually, by the subscriber asking the oper-
ator to plug things together. Ignorant subscribers, frustrated by trying
for hours to reach someone whose line was busy might well say something
to the operator like, "#@@@!!77$ operator! Cut in on the line and tell
them to can the shit so someone else can get through!  #@@%!&%!!! "  Or
they would blame the operator for being incompetent if they got a wrong
number (after having *asked* for the wrong number!); they would flash
to get her back -- especially if they had deposited money in a payphone
coin box they were about to lose -- and give her a good general cussing
out in the process of trying to reach the right number. The operators
had to sit there and take it; a single profane word passing their lips
in response to a beligerant subscriber was grounds for immediate
dismissal.
But if a particular subscriber was always, consistently raunchy and
rude -- cursing at the operators or making sexual propositions to them,
and that happened a lot also -- then the operator would complain to the
supervisor who in turn would tell the Business Office; the subscriber
would be notified to cut it out or risk losing his service.   PAT]
