I had some more phone lines installed the other day, and had the local
telco do the required (extensive) inside wiring for them.  The
installer called each line to demonstrate that each worked and then
left.  When I first tried to call out on one of them, the keypad would
break dialtone but not gnerate tone.  Two hours of work blown by a
simple miswiring!  "611" fixed it at the central office and will drop
by today to do a permanent fix at the demarc.  You pay the
professionals so you don't have that kind of hassle, don't you? :-(

The comet was discovered only last year, and it was September before

confident prediction of a crash.

                  U.S. SENATOR PATRICK LEAHY   - Vermont

                      STATEMENT OF PATRICK LEAHY ON
                VICE PRESIDENT GORE'S CLIPPER CHIP LETTER

                              July 21, 1994

     I have read the July 20th letter from the Vice President about
the Administration's current thinking on Clipper Chip and, to my mind,
it represents no change in policy.  In fact, when this letter was
sent, I would be surprised if the Administration even thought it was
news.

     The letter makes clear to me that the Administration continues to
embrace key escrow encryption technology, and stands behind Clipper
Chip as a federal standard for telephone communications.  The official
standard makes clear that this standard applies to any communications
over telephone lines.  Those communications include not only voice,
but also low-speed computer data and facsimile messages.  The
Administration is working on encryption technologies for higher-speed
transmissions, such as for computer networks and video networks.

     The Vice President says that they want to work with industry to
design a key escrow system that could be implemented not just in
hardware, but also in software, that would be voluntary, exportable
and not rely upon a classified encoding formula.  The Administration
said all this last February when the federal standard was approved.
Yet, when Administration witnesses were questioned about the progress
they had made in this effort at my Judiciary subcommittee hearing in
early May, I learned they had held only a few meetings.

     Last week, the Appropriations Committee accepted strong Report
language I suggested on Clipper Chip.  The Attorney General is
directed to report to Congress within four months on ten areas of
concern about Clipper Chip.

     I agree with the Vice President that balancing economic and
privacy needs with law enforcement and national security is not always
an easy task.  But we can do better than Clipper Chip.

The best I can recall is that {Ramparts} stopped publishing early in

I would consider {Mother Jones} magazine to be the successor to
{Ramparts}.

I'm rather odd myself.

[TELECOM Digest Editor's Note: I used to be odd for quite a few years

conscience of the 19th century, Ms. Jones was once asked by a federal
bureaucrat what was her occupation; what she did for a living. She looked
at him and bellowed, "My occupation? I'm a hell raiser!". Indeed she was.
I can't say that I agree now (or would have back then) with everything 
she preached, but that's not necessary for someone to be a hero(ine) of
mine; merely that they believe what they say and live it as best they can.

Date: Fri, 22 Jul 1994 13:01:26 GMT


 From time to time, a pop record appears with a real (non 555-xxxx)
phone number in it.  Like "Jenny, 867-5309", "BEachwood 4-5789", or a
number mumbled in a heavy metal song "Dirty Deeds Done Dirt Cheap".
And another song "Don't call us, We'll call You" (Sugarloaf?) had some
touch tones in the background.  I suppose there exists a list of valid
but unusable phone numbers due to popular song lyrics.

Like:

867-5309
BE4-5789
(      ) (Dirty Deeds ...)
(      ) (Dont Call Us...)
Pennsylvania 6-5000

Why did the phone system make exchange 555 not useable, other than
555-1212?  Other than maybe a certain "club" in the South might
request all its phone numbers from that exchange.  (Look at the center
letter on the "5" key on your phone).


[TELECOM Digest Editor's Note: PEnnsylvania-6-5000 has been the phone
number of a hotel in New York for sixty years or more. There are other
telco things on 555 in addition to 1212. The AT&T teletype relay operator
for aurally impaired people is on there somewhere, and a couple other
things. PAT]

The July 18 issue of {Crain's New York Business} has an article on the
switch to NNX area codes.  It includes the following statement:

Another, perhaps less important, change is the allowance of a zero or
one as the first digit of a local phone call, currently prohibited.

Can this possibly be right?  Or is the author referring to 1 or 0
being allowed as the middle digit of a local exchange, which of course
has been the case in some places for as long as 20 years?

Arriving in Dublin with a GSM Cellular (digital) phone, I was
expecting service on the local 'Eircell' network, with calls being
billed to my home UK 'Vodafone' network. Having received and made a
number of calls, things were going well, until I tried to make a 'toll
free' call to a 1-800 number. The call was rejected.  Replacing the
GSM Vodafone SIM card with local carrier Eircell, the 1-800 call could
be made with no difficulty. This state of affairs has existed since
the Irish GSM network went live in 1992, but I thought I would
complain about the anomaly.  Customer Services denied there was a
problem "all roamed users on our network can dial the same numbers as
our Irish customers." Trying again, the call still failed.

[As did ALL calls to any number commencing with "1" - Freefone,
Directory Enquiries etc - the only exception was 112 the European
Emergency Services code].

Complaining again, two hours later I received a call from the mobile
network engineers, saying that access had indeed been blocked (in
error) and was now fully open.  This opened up an interesting
situation where Eircell DO NOT CHARGE for calls to DQ and 1-800
numbers, where in the UK these calls are charged at premium rates. It
will be interesting to see if Eircell will pass the information that
it was a free call to my home network, and then watch the home network
attempt to extract a fee for a correctly connected toll-free call.

Subject: SS-1 Signaling
     

Background:

Selective Signaling is a system that sends operator dialed 
digits over an analog private line circuit.  The digits are 
encoded as a series of 2600 Hz pulses with 2400 Hz between 
pulses.  Normally SS-1 circuits do not have any supervision 
i.e., the talk path is always there.  This is a very old type 
of signaling and I think it was only used by the goverment.
     
My Question:

Are there any companies that are currently manufacturing test
equipment for Selective Signaling (SS-1) signaling circuits?  We have
only found one (Ameritec) that offers SS-1 as an option to one of
their test sets.
     
Also, are there any archive files that cover history, development, or
technical specifications for SS-1 circuits and test equipment.

     
Thank You,

The "ramparts" the poem refers to were on an American fort in the war
of 1812-1814.  I suppose one could argue that this isn't "modern"...

For the terminally curious, our online version of Collins English Dictionary
defines "rampart" as follows:

CED
#Hram#+part #5(#!r@amp$a$:t) #6n. 
 @n#1$D. #5the surrounding embankment of a fort, often including any walls,
 etc., that are built on the bank. @n#1$D. #5anything resembling a rampart in
 form or function, esp. in being a defence or bulwark. @m#1?-#6vb. 
 @n#1$D. #5(#6tr.#5) to provide with a rampart; fortify. 
 @m[C16: from Old French, from #6remparer, #5from #7re#5-@t#7#+@t#6emparer
#5to
 take possession of, from Old Proven*,cal #6antparar, #5from Latin #6ante
#5before@t#+@t#6par*_are #5to prepare]  

The Oxford English Dictionary defines "rampart" as follows:

1. Fortif.  A mound of earth raised for the defence of a place, capable of
resisting cannon-shot, wide enough on top for the passage of troops, guns,
etc., and usually surmounted by a stone parapet.
[followed by citations dated from 1583 to 1880.  Interestingly enough, The
Star Spangled Banner is not among them.]

2. Canad.  A steep bank of a river or gorge.  Usu. pl.
[followed by citations dated from 1853 to 1973.]

3. attrib. and Comb., as rampart-base, communication, -height, -line, -walk.
[followed by citations dated from 1799 to 1923.]

I don't find this surprising in the least.  I've been following the
goings-on over at alt.2600, where there was a heated discussion about
whether or not the Repeat Call feature would produce audible
touchtones.  There are an astounding number of people who inquire in
hushed-tone ASCII about such renegade features as the *67 CNID privacy
toggle ("CALLER ID DEFEAT FOUND!"), or who express amazement upon
finding out that recipients (read: the people who pay) for 800 calls
can receive ANI.  Half of the things that enthrall these people can be
found in the front matter of the telephone directory, and the other
half can be found in the Digest.

The idea that telephone company secrets are illegal to possess or
discuss came up in a brief e-mail correspondence.  I referred to a
feature description from an AT&T manual, purchased from the CIC.  The
wannabe hackerphreak in question became very excited at the prospect
of my having this information and wanted to know where I stole it
from!  (I really wanted to make up a little tale about a nocturnal
trip to my local CO, but I just couldn't bring myself to do it.)

This being the post-divestiture era, these sorts of inquiries are not
limited to phreaks.  There was a post on several of the soc.culture
groups from an LD reseller, asking people to send rate quotes for a
one-minute call from their country to the US.  I would guess that a
few simple phone calls could glean this information (and more
accurately) from national PTT's and major service providers.  Of
course, then the reseller might have to *pay* for his market research.
Something tells me that AT&T and MCI use somewhat more advanced
methods.

I hate to think that I'm as cynical as our Moderator on this issue ;-)
but lately it seems as though the old poem should go "30 days have
September, April, June and November, except on Usenet, where September
has 365."

[TELECOM Digest Editor's Note: And furthermore, every day is April 1,
although they do not realize it. Usenet is sinking to its least common
denominator, face it. It was fun while it lasted. I can speak only with
authority for myself, but other mailing list moderators have reported

in moderated groups or private lists such as this one. They just can't

Aw, come on.  Based on the grammar and spelling, I'd say its just some
young kids.  But, maybe not!  I'm hearing "Dueling Banjos!"

I remember picking up the phone on our old Western SXS when I was a
kid (or was it my friend's Automatic GTE SXS?) and noticing that there
would appear to be no voltage for just a moment because there was no
sidetone.  Immediately upon going off hook, there was sidetone, then
no sidetone, then dialtone.  I never thought this was because they
were "switching batteries."  (That was pretty funny) I just assumed
that the line was momentarily open while the line finder worked.  But
maybe the guy authoring the posted opinions drew the wrong conclusion.
