Subject: 205/334 Area Code Split
From: kd4cim@vulcan.com (Jerry Pruett - KD4CIM)
Date: Tue, 24 Jan 95 19:41:33 -0600
Organization: Vulcan - Live Long and Prosper!


On 1/15/95, the 205 area code (Alabama) was split into 205 and 334.
205 remains the area code for LATAs 476 (Birmingham) and 477 
(Huntsville).  
LATAs 478 (Montgtomery) and 480 (Mobile) were moved to the new 334
area code.

The following is a list of the NNXs that have moved to the 334 area
code.  This list does NOT come from any official source, but my
sampling of it seems to agree with the ad posted by South Central Bell
in the 1/16/95 Communications Week.  There is a "grace" period for
which both the 205 and 334 area codes will work, but I left the Comm
Week at the office, so I don't have the exact date.  I seem to recall
the "grace" period ending in June or July though.  For more precise
information for programming PBXs and such, call SCB (they had an 800
number in the Comm Week ad).

At the end of the "grace" period, I assume that SCB (or is it 
Bellcore) 
will start assigning new NNXs that may duplicate in the 205 and 334
NPAs.

Again, this following information is NOT guaranteed as it is extracted
from a personal database.  My use of the database requires that I keep
it as accurate as possible however.  For exact details, you should
consult the Comm Week Ad and/or call SCB.

Hi,

I am looking for some information on implementations of the German 
SISA 
specifications for management of PDH/SDH equipment. I'm lokking for 
the
following kind of information:

1) Which vendors of PDH/SDH equipment are supporting the SISA specs? 
This
   would help us to decide whether to implement an equipment specific
   solution or to go for a more generic approach.

2) Are there any implementations of the SISA protocol stack available
   out there (freeware or comercial)?

I was wondering if anybody whould know of any information source
regarding marine teleommunications installations.  The question I am
facing is the installation of some voice/data lines on a marina.
Ideally the boats should be able to dock and hook into the marina
network.  Are there any special products (connectors, cables, etc.)
for marine installations?  Are there any other information (standards,
past experience)?  I would appreciate any help.

Subject: Difficulty With Atlantic Bell ISDN


My office (located in Eatontown, NJ, area code 908) recently had two 
ISDN 
lines installed for experimental purposes.  We receive our ISDN from a
#5ESS.  It was obvious, despite what is written about Bell Atlantic in
"Reengineering the Corporation," that it is very inexperienced and
unorganized in providing ISDN service.  All we asked for was two ISDN
BRI lines with NT-1s.  It took about two months before we were able to
get the lines installed, and we have already had to replace the NT-1s
once.  Anyone else have experience with Bell Atlantic ISDN?

Given the fact that phones are given away free with subscription, does

I changed service and was able to purchase a new phone (the exact same

Now, I am left with an old phone.  Is taking it apart to see what's

its only value?

Subject: Technical Help Needed With Pending Litigation 


I need a specific technical question resolved for pending litigation
with Bell Canada. Here it is:

Is it physically possible to infiltrate a telephone company's network,
remotely manipulate the company's switches; process long distance
calling; make it appear that those calls originated from a particular
site and the subsequently billed to that location?

Can anyone answer this question or lead me to the individual(s) that
could?  Any help will be justly rewarded and sincerely appreciated by
yours truly.  Please leave a way to get in touch!  However, if you
prefer to remain unknown, thanks a million, and rest assured that I
will respect and protect your anonimity.

Thank you for your help in this matter.


Regards,

John P. Marinelli       jmarinel@freenet.niagara.com


[TELECOM Digest Editor's Note: Yes, this generally can be done. It is
not real easy, and requires a degree of sophistication by someone who
knows how to do it. It involves getting into the telephone network 
using
a 'backdoor', using a dialup and passcode. In other words, what I am
saying is certain switches have a phone number you can dial into, give
the correct passcode, and then manipulate or make changes to the way
calls are processed as though you were in the central office itself at
a terminal and keyboard. Quite a few telcos have disabled this 
'feature'
for obvious reasons. I guess some still have it available. I would not
have the slightest idea *what* commands/passcode to use, nor the 
numbers
to dial to get into the switch. The commands probably stay the same 
from
one switch to the next more or less, but certainly the phone numbers 
and
passcodes are different. Plus, I strongly suspect anyone fooling 
around
like this leaves tracks all over the place leading back to them.

 Well, Pat, I tell you how much it is in Germany. Calls to the
States from here cost you the (rounded) equivalent of 15 cents for 
every 
seven seconds of your phone call. That means billing is in those seven
second increments as well; so if you make a phone call of, say, ten
seconds you pay 30 cents and give the PTT a gift of four unused 
seconds.
Hence, assuming it is possible to type six buttons on your phone
within seven seconds (to enter your PIN), your initial call to the
callback company costs you 15 cents.

 Now for the rates: I have seen Callback services that charge
as much as 75 cents a minute; but the chepeast I came across so far
was 51 cents per minute with a 30 second minimum and billing in six
second increments. And that is without a monthly flat fee, or call
surcharge. (Note: This is only for calls _from_ Germany _to_ the US of
A.)  So, a three minute call the direct way (ie. with "wonderful"
German Telekom) costs you about $3.75. (This is all rounded). Using
the Callback service it is $1.53 plus the 15 cents I used to call the
Callback service, ie. $1.68. That's more than 50% cheaper!  Things
from France may look a little narrower, because German Telekom, as far
as I know, charges the most in Europe, perhaps even in the world
(which wouldn't surprise me.)  But still -- you can apparently save
from France too.

 They were?  Was unnoticed here.

 Go right ahead. It is cheaper. The more competitors the better.

 Well, what's the difference (in terms of security) between calling a 
number, letting it ring a couple of times and calling a number and 
_letting_ 
them answer to punch in your PIN?  I don't see any. The point you 
originally 
tried to make I didn't understand either: misdialed calls.  If someone 
has 
your Callback number, he stole it or got it in some other illegal way.  
People
can steal Credit Cards or Credit Card numbers too and cause quite some 
harm 
to you, although a harm more of the subtle kind -- it doesn't wake you
up at three o'clock in the morning. Instead, it lets you sleep and 
comes in 
the (later) morning in your credit card bill.

[TELECOM Digest Editor's Note: Yes, AT&T was claiming that deliberatly
causing a phone to ring then disconnecting amounted to sending coded
transmissions without paying for them (which it does). When it was 
noted that AT&T's own answering machines use 'toll-saver' techniques 
the same way (if ringing phone does not answer within two rings, 
disconnect
since there are no messages waiting for you), then the company found 
it
difficult to object to others using their network in the same way.

The difference between merely calling a number, letting it ring a 
couple
times and hanging up versus dialing a number, waiting for an answer 
and
specifically entering a PIN number is that the former happens how many 
ever millions of times daily when clumsy people dial wrong numbers and
realize it within seconds of finishing the dialing. They then hang up,
but the callback switch has no way of knowing if the real user was 
giving
a signal or if some careless person caused that to happen. At least by
inserting a PIN, a positive, specific effort has to be made. Most 
wrong
number callers and telemarketing people don't get that far along.

Thanks.

The company I'm working for is developer of voice-processing software.
We are also distributor of Dialogic Voice hardware. You can start with
a two or four lines board and when you need more capacity, you youst
plug in extra boards. All Dialogic boards come with manuals and 
drivers 
that allows you (if you are a good programmer) to make everthing you 
want 
for the DOS OS.
