Subject: East TN to Get New Area Code
Organization: Siemens Industrial Automation, Johnson City TN
Date: Mon, 18 Jul 94 19:28:01 GMT


East TN, that area of the world that includes Chattanooga, Knoxville,
and the Tri-Cities (Kingsport, Bristol, and Johnson City), will be
getting a new area code as of Jan. 1st, 1996. This was reported in the
Johnson City Press, Thursday, July 14, 1994. The actual code has not
been determined yet: they are leaning towards 249, but 931 is also
possible. They would rather use 249 than 931, as 931 might be confused
with 901 currently used for West TN: the area containing Memphis.
Middle TN would still use 615 (it contains Nashville). When the new
area code becomes dialable, and how long permissive dialing will be
allowed was not reported. The exact boundaries were also not reported.

The article stated that they are doing this as faxes, modems, etc.
will soon use up all available numbers in the 615 area code. This has
happened pretty quickly, as last year they went from 1+7 dialing of
long distance within 615 to 1+3+7 for all inter-lata long distance
inside 615 for the very same reason and are soon run out of the
numbers that were freed up by that.

Subject: Remote Network Access?
Date: 18 Jul 1994 22:03:40 GMT
Organization: University of Pittsburgh


My Telecommunications Applications class (in the Master of Telecomm
program here) is charged with helping the University determine how
students, faculty, and staff will access the net from home.

We have determined thus far that high-speed modem pools of POTS lines
will continue to be the principle access method.  (Ie, we will continue 
to have racks of modems and lots of copper coming in).  SLIP is or
will be available in the modem pool.

We are also interested in ISDN and any other access method.  We have
not heard of any such 'production' use.  We would likely use a UNIX
machine as a security gate for the network, direct from the ISDN.  Any
advice/stories are welcome/appreciated.  


Thanks,

Seth Rothenberg

Subject: Tricks That LD Companies Play
Date: 17 Jul 1994 22:10:00 GMT
Organization: University of Washington


The recent thread about some of the early sins of long distance
companies brought two of my favorite to mind.

It was not uncommon (might still be common now, but I am out of the
biz) for alternate (non-AT&T) companies to charge for the rings.  They
would hide this by always having six second billing AFTER the first
minute.  Here's how it worked.  Lets assume ten rings per minute, one
every six seconds.  You have signed up with a new long distance carrier,
No-Tell.  You call grandma.  Grandma takes a long time to answer, so
you let it ring fifteen times.  

With AT&T and No-Tell, if Grandma doesn't answer you don't get billed.
Both have answer supervision.  Let's say Grandma does answer, talks to
you for 20 seconds, then forgets she is on the phone and hangs up.
With AT&T you would be billed for a one minute call.  With No-Tell you
would expect a one minute call, but instead you get a 1.8 minute call.
1.5 minutes of rings, and a third of a minute of talk.  Voila, you are
retroactively billed for all rings as soon as a call supervises.  You
have to keep pretty close track of your bill to catch that one.

Trick number two: In a former life I worked for an LD company that
found itself in financial trouble.  We'll call it No-Tell, again.
Some hotshot fixers were hired, and the first thing they did was raise
every rate in the switch by two cents per minute.  From one side of
the country to the other, not that big an impact.  From one side of
the county to the other (what a difference a letter makes), a night
weekend rate of two cents per minute shot up to four cents a minute,
making it one cent a minute higher than AT&T.  All No-Tell bills
showed clients how much they saved vs. AT&T.  Residential bills were
saying things like, By Using No-Tell You Saved -3.25.  That's right,
our bills were showing how much more they spent with No-Tell than they
would have spent with AT&T.  How did the hotshots deal with this?
They raised the AT&T rates by two cents per minute.  That's right, our
bills just plain lied about the AT&T rates.  That was when I quit that
job, and started selling yellow page ads.  But that is a different
story ;).

Subject: Headline "800 Purveyor Faces Obscenity Charge"


A severely truncated article datelined Montgomery, Ala. was in today's
paper.  Says Mark Carriere of Los Angeles, operator of Mark III
Entertainment, an 800[sic] sex-talk "service" is going on trial in
Alabama.  Identifies the prosecutor as Asst. Attorney General Bruce
Lieberman, who works for someone named Evans, otherwise unidentified.
Says other 1-800 services "may soon be dialing up a court date."

I'm wondering about parallels between this case and one that is being
talked about a lot lately on the net.  In the latter a San Jose
computer BBS operator is being tried in Tennessee on porn charges.
Now in this case it seems that a federal court in California has held
that what the BBS operator is doing is not illegal; but the federal
court in Tennessee is claiming that it is illegal there, and since
some Tennessee citizens accessed his BBS he can be prosecuted there.

Subject: Anyone Use NT Magellan Switches?
Reply-To: peisch@cfa.org


I'm about to 'take off ' to Ottawa for Magellan training for the MAS
and Passport/DPN-100 products.  Our implementation is for an IP data
network and we're pretty disappointed with the throughput of the MAS
product (can't handle a DS1 circuit) though it has an embedded Cisco
2501 router.

Where we're going to put the MAS products, wouldn't it be better to
put in just the Cisco router with a frame relay interface and use the
full DS1 (the cost difference between DS0 and DS1 is negligible in our
market)?  The NT sales got all huffy when this was suggested as he saw
his comission drift away.

The NT engineers we've been talking with don't seem to have a clue
about IP networks and I'm learning about trunking and things.  Are we
asking for trouble?

Anyone using such devices, please comfort me that the NT sales folks
aren't just selling hardware to line their pocket book.

Subject: AT&T's New Overseas Transmitting Facility - An Update


Last year, I reported that AT&T had filed a tariff to build an
overseas cable plant going from Shirley, Long Island, New York, to
France.

I went by there a little while ago while taking my son and some of his
friends to the ocean beach and am offering this update.

The building is up and has been for several months; cable, inside
conduit, is laid from there to almost where it will have to go
underwater to cross the Great South Bay, thence across Fire Island
between or near the border of Smith Point County Park and the Fire
Island National Seashore.

Near the northern edge of the bay, the conduit is above ground and is
on what looks to be temporary supports although the currently southern
end dips back into the ground.

The contractors, some local, some from other areas in New York and
some from other states are all involved.  A former campground for the
County Park has been turned into a staging area for various types of
equipment, most notably tankers containing thousands of gallons of
potable water.  The place is a beehive of activity.

It should be noted that New York, Long Island in general and Suffolk
County in particular has not even begun to recover from the
devistating effects of the last recession.  Unemployment is at its
still record high and this work is a major boost to our, meaning my
hamlet's and two other adjacent one's economies.  Yes some of the
money will leave the local area; however, we are willing to take any
jobs-producing work that we can get.

Hat's off to AT&T for selecting the site for its new overseas cable
plant in an area that will indirectly benefit many in the future
through the taxes that will be paid on the building and its equipment.

[TELECOM Digest Editor's Note: I think you are going to find that when
the change becomes official next year, there will be a huge rush of new
area codes coming up all over the place, making it difficult or impossible
for most people to keep track of them. Carl Moore regularly prepares a
history of area code splits and I suspect next year will be a very busy
one indeed for him. I post them as I get them, and I suspect by next year
this time there will be places that have split even after their original
split. Take for example our split to 708 from 312 here a few years ago.
Now we are going to have 630 as well. Its going to get crazy.   PAT]

Subject: Fraudulent 800 Number Sex Line Charges
Date: Mon, 18 Jul 1994 22:35:20 -0800
Organization: CRL on San Francisco Bay


A buddy of mine called a supposedly free sex line.  After an initial
preamble, he was told to enter a code on his phone that would give him
free time.  He entered the number, and the other end shortly hung up
without providing him with anything.  A month later, he gets a charge
on his Pacific Bell phone bill for $30 for two minutes connect time to
"Network Information Services" or some such.  He tried the 800 number
from a pay phone, and instead of giving him an access code, it instructed 
him to dial a number beginning with 011.

Today, on the NBC nightly news, they ran an item concerning this very
problem.  They explained that, because it was an 800 number, that the
called party is able to get your phone number (this I already knew).
What they did not explain is why a telephone company will bill a
customer on the basis of a request from some called party with an 800
number.  Is this some new service?  Apparently, Nynex has discontinued
such charges.  The item said that even if Congress enacts lecgislation
to outlaw this sort of fraud, that the companies will just move off
shore.

Any clues?


[TELECOM Digest Editor's Note: Telephone Information Providers can 
contract with telco to do thier billing for them; they usually do it
however through a firm such as Integratel which is already set up for
that purpose and which has the billing equipment and procedures already
in place.   PAT]

the format of the data? Is it ASCII or mixed?


Thanks,

Scott

Pat,

If you'd like another example of blatent commercialism of the net :-) :-)

Hello Direct's catalog is available to mosaic users at:
url    http://www.hello-direct.com/hd/

Also, they have an email account on Compuserve, which would be
74577.425@compuserve.com from the Internet.

In their catalog, they have a new 900 Mhz cordless headset. No mention
if it's spread spectrum, digital, or analog.

[TELECOM Digest Editor's Note: Hello Direct is a great company with
some good deals where telecom stuff is concerned, although I sometimes
think their prices are a little high. USA readers can call them to get
on their mailing list by dialing 1-800-HI-HELLO. Regards their blatant
commercialisation of the net, I hope they do better at it than I did
with the Orange Cards and Telepassport stuff. I still get a tiny check
every month or so from Orange on the commissions from people I signed
up who use the card. A couple of the telecom firms I sold stuff for did
not ever pay anything at all; it seems they are as good at ripping off
thier sales reps as they are at lying to their customers.   PAT]
