CLASS (SM) features require end-to-end SS7 connectivity.  End-to-end
SS7 connectivity means that every trunk over which the call passes
uses SS7 signaling.  The path from the originating end office to the
IXC point of presence; the LEC/IXC interface in the originating LATA;
the path through the IXC network; the IXC/LEC interface in the
terminating LATA; and the path from the IXC point of presence to the
terminating end office must all be SS7-signaled trunks.

Currently, the LEC/IXC interfaces are virtually all MF-signaled, not
SS7.  Note that for CLASS (SM) features to work on an interLATA call,
both the originating *and* terminating interfaces must be SS7.

SS7 interconnections between LECs and IXCs are slowly being deployed;
I've seen in the last couple of issues of {CommWeek} a Southwestern
Bell legal notice of tariff filing of SS7 access arrangements, and I
know I've seen other LEC notices in the past.  It's getting there.

Repeat call, or whatever name the LEC has given it, doesn't retry the
call; it requests the terminating switch to monitor the status of the
called line, and when the line transitions from "busy" to "idle", the
terminating switch sends a SS7 message to the originating switch.  The
originating switch then rings the calling phone (if idle), and when
you pick up, re-originates the call.  This requires end-to-end SS7
also.

I fail to see the stretch that equates "LATA" with "neighborhood". In
our case, the CLASS features will not even cover the entire LATA
(excluding the 707 area) initially. But what amounts to the
nine-county Bay Area is quite a chunk of real estate. An area
consisting of several thousand square miles is not my idea of a
"neighborhood".

But as I was reading the phone book in the hotel room yesterday
morning in Reno, I was once again reminded that the whole world is not
California. The book described "Custom Calling 2000" which is the
entire litany of CLASS features. Yes, Nevada Bell (a Pacific Telesis
company) offers Caller ID and no per-line blocking. Of course, it is
Nevada, not California. For some strange reason, the state of Nevada
does not find it necessary to pass laws that cover every single action
one can perform in his wakeful condition.

I saw people riding motorcycles without helmets (I would never do
that, but it is nice to have the choice), people riding without
seatbelts, and Caller ID. California, in its infinite wisdom, has
decided that these things (as well as thousands of others) are not
allowed. So a state that cannot even pass a budget on time (or at all
so far this fiscal year) as required by law, can still dictate to its
residents all of the things that they cannot have or do (for their own
good, of course). Yes, I know that PUC rules and laws passed by Willie
Brown and his friends are two different animals, but the effect is the
same.

Oh, the size of the LATA involved? Try half the state. Pretty good
sized neighborhood if you ask me.

A quibble, but the NEC is a model code, not a law, and has effect only
when a local jurisdiction adopts it by law.  A jurisdiction frequently
adopts most of a model code, but with some local changes.  There are
multiple competing codes for fire, building, life safety, and so on;

The Grand Master of Clocks is named Hubert Wollington III (it is one
of the few hereditary positions in the USA) and he doubles as the
official government standard for riboflavin.  He is usually kept in a
bell jar slightly to the left of the U.S. Consitution in Washington,
D.C.

The Wollington family is noted for its devotion to public service.
Hubert's sister, Jane Barbe, was for many years the voice of time at
WWV and WWVH (shortwave radio stations operated by the U.S.
Government); his mother, Jessye Norman, sang the 1000 and 1200 Hz
ticks and minute markers at the radio stations, and his aunt, Anne
Jones, was the official Canadian censor until she married Henry
Spencer and converted to Collyerism, a religion similar to Unitarian
Universalist, but concerned more with the exact date of the Ascension.
She devoted the rest of her life to correcting time header format
errors in the Dead Sea Scrolls.

Hubert has two sons, Ante Meridian and Postal Mail, and a daughter,
Principia Mathematica.  Like most men, he was briefly married to
Elizabeth Taylor during the 1970's.  He is currently single, cute, and
available, but poorly-paid.

Any facts in the above are unintentional and should be reported
immediate to the Brain Tumor Marketing Council.  Thank.

Well, I've finally graduated (and lo, the heavens parted and down upon
a beam of light descended The Diploma ...) and am now doing gruntwork
on that ever-popular 8-to-5 basis.  (Yes, I'm up past my bedtime.)

The company I'm working for has a PBX with a mix of DID and non-DID
lines.  It's a "Meridian Mail" system, which seems to be Northern
Telecom hardware with a Pac*Bell sticker on it, although that
evaluation comes from a less-than-exhaustive analysis of the box on my
desk.  This company has an office in Switzerland (which wins my prize
for most repetitive phone number -- country code 41, city code 41,
phone numbers 41-XX-XX).  Anyway, up until "recently" (some time
before I arrived, but I've heard this from several different people),
to dial an international call, you had to dial:

 9 + 1 + 011 + country + city + number

The less-than-Digest-level-telecom-literate people I've talked to were
of the impression that Pacific Bell required the "1" before the "011"
until recently.  I assured them that it has never been PERMITTED, but
they insist that this was how it was done, and have tales of
reprogramming fax autodial lists to back up the story.

The only thing I can figure is that it was something analogous to
hotels where you dial "9" for a local call but "8" for long distance
 -- the PBX ate the "91" as indicating "grab a toll trunk," and then
dialed the rest into the PSTN.  Since the "1" has only recently been
required for domestic long distance, it would at least be
semi-coherent.

Seeing the braindead stuff they do with much of the phone/computer
system there, I wouldn't put such silliness past them.  They also have
some "secure" phones with some sort of encryption, I guess, for
calling government people, but I haven't tried dialing 710, and only
used "the black phone" once when I needed to call my answering
machine.  (The regular phones do the "blip" outdialing instead of
matching my finger timing.  Very annoying.)

The call is not actually retried every 45 seconds.  For origination
queueing, your CO is sending a message via the SS7 network
periodically to query the status of the target line.  If it is busy,
nothing happens, and it queries again a bit later.  If it is idle,
your line is rung; when you answer, the target line is rung and the
call is considered complete.

Thus, since SS7 messages are used to query the line status, this
feature will not work unless there is SS7 connectivity between you and
the target line.

If so, what wires go where?  In other words, how do you make a
jack-to-jack adapter?  Are the dialing tones the same, or do I need to
pulse dial?

What can I do to prepare here in the U.S. before I go, or do I need to
take a soldering iron, multimeter, wire strippers, etc. (I wonder what
airport security would have to say about *that*).

My knowledge of the term suggests DS "zero" and not DS "oh".

As such, DS0 would be the analog input/output, or voice channel before
being digitized.  DS1 of course then is a T-1 span of 24 digitized
DS0s, DS2 then meaning four DS1s (96 DS0s) and DS3=28 DS1s (672 DS0s)
etc, etc.

Running DS0 over fiber sure seems to me like a terrible waste of
bandwidth ... IMHO.

	I would suggest that you don't use a pencil eraser.  As one my
previous jobs, I worked as a technician on some 1 MW peak radar
systems.  The filament voltage for the final tube in this thing (no,
it wasn't a magnetron) needed 1.5 V at 900 Amps.  The connections
consisted of a metal blocks with thick copper braids that were clamped
directly to a similiar blocks on the tube in question.  As can be
imagined, there were over current, under current, overvoltage and
under voltage sensors all around this thing so that any increase in
resistance in the contacts would shut down the system.  Therefore, us
techs who worked on this thing were very interested in keeping the
contact resistance down for as long as possible.

	As it happens, most pencil erasers have some sulfer in them;
so, while one could use the eraser to get rid of the surface corrosion
and temporarily make better contact, the sulfer traces left behind by
a pencil eraser would react with water in the air, making sulfuric
acid that would corrode the metal.  A little extra fine emery
clock/steel wool is therefore better than the pencil eraser; a dose of
denatured alcohol afterwards can get rid of the particles.  While we
didn't use any at the time (this was a looong time ago), a little
conductive grease to exclude air at the point of contact might be in
order; this stuff can be found at any reasonable electronic parts
store.

Yes, when you can find them.  For instance, the Little Rock phone book
used to dedicate the first page to all the numbers of the police,
fire, etc.  departments in central Arkansas.  This now has been
reduced to a listing for all major services of 911 (in big print).
Referring to the "helpful numbers" section in the "blue pages" gives
police in most communities as 911.  Only looking under city government
can one find the actual police numbers.  Even there though, the fire
department only gives a central number, not station numbers.

I have no problem with pushing 911.  But when > 50% of the first page
of the directory is now blank, why not publish the direct numbers too?
