   No mistake, just evolution of the dialing plan.  The following
states have indicated they will permit 1+10-digit dialing for ANY
number in the NANP (the first column indicates if Home NPA Toll calls
can also be dialed as 7D, or requires 1+ for Toll)

 7D   California - by 5/94
  1+  Dist. of Columbia - see below
  1+  Maryland - see below
  1+  Nevada - by 7/94
 7D   New Jersey
 7D   New York - date unknown (works for 212, 718, 917 now?)
 7D   Pennsylvania
  1+  Virginia - see below
 7D   West Virginia - by 10/94
  1+  Wisconsin - by 10/94

   The Washington, DC metro states (Maryland, Virginia and DC itself)
support 1+10D dialing for all numbers, but non-metro NPA 703 and the
rest of Virginia may not be ready until mid-94.  These states also
support 10D dialing of Foreign NPA LOCAL calls, and non-metro Virginia
areas support 7D dialing of such calls.  (NPA 703 in Virginia will
permit 7D or 10D or 1+10D local calls, except into the Washington
metro area, where 10D or 1+10D is required.)

   Illinois is the ONE state that REQUIRES 7D dialing for all Home NPA
calls, even Toll calls (i.e., does not PERMIT 1 + 10D for such calls).

   New Hampshire (by 8/94) will permit either 7D or 1+10D for Home NPA
Toll calls, but requires 7D dialing for Home NPA Local calls.  Foreign
NPA Local calls require 1+10D.

   Some states are requiring 1+10D for Foreign NPA Local calls
(Louisiana), others are requiring 7D (Oklahoma) and still others
require 10D (Texas).  There's probably some place at their
intersection where moving in a small circle will hit all three dialing
patterns.

   This analysis does not include Maine or Massachusetts, because I
have not received IN WRITING any indication of their plans ...

Coming from a T1 background, I have limited knowled in regards to E1.
My company is involved in selling products into Europe. But it very
hard to obtain expertise on practical applications in the E1 realm. I
have a few general questions:

1) At loss of signal from the DTE, what is the proper signal to
emanate from the CSU/DSU towards the line side (using CAS signaling)?
What comes out of Timeslot 0, 16 and the remaining data payload.

2) What is IRSM switiching mode and how and where is it implemented?

3) What is the repeater spacing on an E1 line and is there an end
section (last repeater berfore entering the customer's site) repeater
specification?

4) What are the variances from country to country in repects to the use 
of the national bits and international bits.

If there is some place/person on the internet that will provide this
information, I have a ton of questions.  Any help you can provide will
be greatly appreciated.

Back around 1967 or so I saw a system in use at the TWA terminal at
what was then Friendship (now BWI) Airport.  It consisted of a fairly
normal ball-point pen connected to a plastic tab going into a box. It
also had a wire coming off, giving a simple switch closure when the
pen was pressed against the piece of paper on the top of the box.  The
box read the pen motions and sent them to a receiver elsewhere in the
terminal, which operated a stylus to duplicate the writing onto
another piece of paper in real-time. The paper on the transmitter and
the receiver where both adding-machine type paper rolls which could be
pulled out a few inches at a time, and torn off, and stuffed into a
pocket.  The pen on the receiver had no visible ink reservoir, so I
suspect that the paper was electrically or heat sensitive.

Hi,

I have been given the 1-800-xxx-xxxx numbers of four companies in the
US that I need to contact -- unfortunately I do not have any other
number for them, and was hoping that someone in the US could tell me
either the normal number or a fax number for them.

The companies are:

Smart Micro :      1-800-ROM-BIOS
Bios Upgrades:     1-800-800-2467
Cmos Solutions:    1-800-266-7462
Rom Bios Upgrades: 1-800-541-1943

Any other means of contacting them would be most helpful.

(All I do know is that they are supposed to be in the CA phone books!!
 -- not a lot of help in the UK ! )

Thanks in advance for any assistance ...

Subject: Looking For Phone Number/Directory Anecdotes, Lore, Predictions


As part of a series of short radio pieces for our local CBC Radio
affiliate called "A User's Guide to the Future," I'm preparing an item
which centres on the past, present and future of everything to do with
telephone numbers.

I'm looking for anecdotes, lore, predictions, etc. about telephone
numbers and telephone directories.  I'm not looking for specific
technical details, just interesting information about different ways
of communicating telephone numbers, compiling telephone numbers,
spelling things with telephone numbers, about the history and future
of the "phone book" (how having all of North America's telephone
listings on a set of CDs changes telephony, for example), personal
"portable" telephone numbers, etc.

I've been impressed with the quality of the "asides" that correspondents 
often to contribute to the Digest and wonder if I might impose upon you 
all to contribute some by email to me :-)


Thanks.

Ringing is a low-frequency AC signal applied to the line (Typically 90
volts at 20 Hertz).  Tell the repair desk that "ringing voltage is not
being applied".  They will likely find the problem to be the line
equipment (printed circuit card in modern exchanges) feeding your
line.

Ruling in circuit court in Louisiana (if I remember right) a
few years ago held that the use of cellular telephones constituted the
use of a *radio device*, therefore was subject to the de facto
principles of radio reception, i.e, that no reasonabl e expectation of
privacy was afforded radio users and therefore none could be
guaranteed by a court of law.  Note that this principle applies only
to the air interface; once the call gets into the wired system, it's
called wiretapping and is still illegal without court order.


[TELECOM Digest Editor's Note: However the court ruling to which you
refer is a very grey area. The FCC thinks otherwise, as do the federal
courts in some jurisdictions. Best not listen to cellular calls.  PAT]

Delrina (the makers of WinFax and PerForm) has just announced a fax
mailbox service exactly as you describe.  It will ship (i.e. be
available) in about two weeks time.

It provides you with a personal 1-800 telephone number which can
receive faxes or voicemail.  It also has a paging notification feature
which you can have page you when a fax arrives for you in your
mailbox..

To receive your faxes onto your computer, just click on 'Retrieve From
MailBox' from the Service's menu found in WinFax PRO 4.0.  Type in
your password, and your faxes will automatically be sent to you.  If
you don+t have your computer, or access to one, you can instruct the
service to send your faxes to a fax machine.  Your faxes are retrieved
from the same 1-800 number so there are no long distance access
charges.

It is currently the ONLY way to retrieve a fax sent to your fax
mailbox directly to your hotel room with your laptop.

You can call your Fax MailBox either from WinFax PRO or using a touch
tone phone to find out if there are any faxes waiting for you.  The
service will let you know how many faxes you've got, how many pages
are in each fax, and at what time each fax was received.  And you can
even pick and choose the faxes you want sent to you immediately, while
leaving others in your mailbox for retrieval at a later time.

Other options are available including DID numbers (for international
access), and voicemail options (the same mailbox can also take your
voicemail messages).

Also your telephone company's "call forwarding" service lets you have
your faxes forwarded directly to your MailBox.  If you want to receive
your messages immediately, either to your office or an out of town
location, simply call forward your Delrina Fax MailBox number to your
current location.  Your messages will be automatically transferred.
And if that line is busy, your transmission can be rerouted back into
your MailBox through your phone company+s "call forward when busy"
service.

For more info you can call Delrina in California at 1-800-268-6082.

I'm not sure if someone read the post to the Digest or perhaps a
manager at Pagemart was made aware of the situation by my inquiries,
but whatever the case may be, it seems to be back to normal, at least
for the past two days it has been!

I'll keep checking to make sure that they don't try to go back to 15
digits. (No big deal, most of my pages are over 15 digits so in the
event that limit is set back down at 15 I'll know about it shortly
after they enact it, which of course I hope they don't!)
