{I should preface these remarks by saying that I'm not really
suffering too badly due to this outage since I've got other ways of
making outgoing calls and my computer data lines do work. But the tone
does represent general frustration with the lack of a competitive
marketplace.}

It's too bad there isn't local loop competition yet. I like to fantasize
innovative services.

My phone (and a few hundred others) have been out since Friday even
due to some sort of cable break. It is supposed to be restored by 5pm
Monday (Of course, it's slipping day by day).

I finally asked them to busy out my lines so that callers don't simply
get a ringing that indicates I'm simply too arrogant to own an
answering machine.  Why isn't SOP to place an out of order signal on
the line. The only explanation is they're the Phone Company (Capital
letters since there is only one!!). Of course, if they had a modicum
of intelligence they would provide a recording explaining the problem
and offer free voice mail services until the serivce is restored and
then automatically forward the message (like ATT does for its message
forwarding service). But, again, why should they bother.

When I call repair, I randomly get a service that asks me to key in my
phone number (after waiting till I hear enough of their message
because they can't hear tones while they are blabbering about how to
operate the silly system).  Of course, when I do get a repair person,
the number doesn't appear on their screen. That would take some
internal coordination.

I'll writeup my ISDN experiences separately. I do have ISDN working
but the sales literature hasn't been updated since about 1980 when
they though 9600 bps was fast enough for LANs. They are clueless as to
uses for the service.

My wife's reaction on reading this is MONDAY 5PM!!!!!! She's not
as calm about it. My reaction is moderated by my limited expectations.


[TELECOM Digest Editor's Note: Exactly where is/what caused this cable
problem and why is it taking three or four days to fix?  Be sure to ask
for credit for the time your phone was out of service.   PAT]

Subject: History of Numbers in UK
Reply-To: [e-mail]


Thomas Miles <[e-mail]> said, about numbering in the UK:

BEFORE the STD system arrived here, all numbers on automatic exchanges
had an exchange name, and between two and five numerical digits.  Not
all the numbers could be dialled directly when calling from outside
the area served by each exchange.  Two digit numbers were on very
primitive exchanges, and in all cases the Post Office operator had to
set up every out-of-area call to and from these numbers.

In the six largest cities (London, Birmingham, Liverpool Manchester,
Edinburgh and Glasgow) every exchange had a "local" name and the first
three letters of this were the dialling code from nearby exchanges.

This (almost) equated to the system used in the USA, except that in the
UK it was always three letters and four digits - there were no cases of
two letters and five digits.

> Dialing the STD code for local calls worked, but I understand you got
> charged a toll rate.

Not true.  The charges were the same, whether the "local" or STD codes
were dialled.  Except, of course, where the "local" code was a
concatenation of other local codes designed to bypass the STD charging
system.  Until STD arrived, the UK had flat-rate-per-call calling for
local calls; after that even local calls were charged by duration
(except in Hull where the Post Office's warrant did not run!)

> some numbers could be dialed in as few as seven or eight digits
> from anywhere in the UK).

Never seven digits -- the routing system would not accept less than
eight.  But eight digit (national) numbers still exist in a number of
places (although they are mostly being phased out at the moment).

> things are moving to everyone having a four digit STD 0XXX and a six
> digit number.

Not true.  Things are moving to everyone having a ten digit (national)
number -- some in the form four digits code + six digits local, but
there are several parts of the UK where five digits code + five digits
local will remain the standard -- at least as the current plan stands.
And in the "larger cities" the original standard remains: three digits
code, plus three digits district and four digits local number.  The
"larger cities" include London, Birmingham, Liverpool Manchester,
Edinburgh and Glasgow, plus the area round Newcastle which works
differently.  Next year (April 1995) five more cities will be added to
the list: they are Bristol, Leeds, Sheffield, Nottingham and Leicester.

> Also, more All Figure areas have been created

Only the one (Area code 091).  This includes Newcastle, Washington,
(*not* DC!) Durham and Sunderland.  In all the other "larger cities",
all calls within the city area are treated as a single zone for
charging purposes ... in 091 there are three separate charging zones.

> Beginning next year, the STD goes up to five digits

Only some of them!

> STDs were assigned in alphabetic sequence based on the major routing
> exchanges, not geographically

Not quite.  Every exchange was put in a group (for charging purposes)
and the group was given a name -- usually that of the town or county
etc -- from which one or (usually) two letters were extracted.  These
letters, plus an arbitrary digit, became the rounting code (which was
always prefixed with a "0").  Thus I was (and still am!) 0CA2 for
CArdiff; while a village six miles away was put in the 0GG6 group (for
GlamorGan county).  Some letter combinations were a little artificial,
but that was unavoidable given the need to make the best use of all
the available codes!

And PAT added:
> telephone area codes here are a hodge-podge; they are whatever they
> are wherever they are. 212 is in New York and 213 is in California
> some four thousand miles away. 316 is in Kansas while 315 is also in
> New York, with 312 in Chicago, 313 in Detroit and 314 in St. Louis.

I understood that the US system was designed to minimise the register
holding time, for pulse dialing callers.  Thus New York, the most
popular destination, got 212 ... Los Angeles 213, etc.  There were
other rules limiting adjacent combinations but that was the basic way
the system was set up.  With all that effort to reduce register
holding times, it's a bit odd that telcos still charge *extra* for
tone dialing!

I figure that by now, someone has invented and is marketing Caller ID
boxes for the blind that speak instead of (or as well as) putting the
number on a LCD display.  Where do I find one?  I am not visually
impaired, but it sure would be convenient to be able to just listen
for the ID when the phone is ringing rather than having to stop what I
am doing and always run to the box to look at it.  Any ideas out
there?

Greetings:

Has anyone heard of a long distance carrier named Excel
Telecommunciations?  My friend has been invited to join in this
"business opportunity", however in my experience and with my industry
knowledge (albeit limited, see my .sig), it strikes me as not being
legitimate, although they make many claims that I am trying to verify.

Please note that I have absolutely no interest in this project, other
that the fact that being the "computer and phone guy" gets me tapped
for free advice more often that I like. :-) Anyone else with that
problem?

Please email me, and I will post a summary if there is any (unlikely)
interest in the follow-up (please email me about the summary also to
avoid the "inevitable" me-too posts)..

Thanks for any help that you can offer.

Is there anybody who likes the name of PacTel's new spin-off

article regarding the name decision and they brought up the fact that
UAL's name change to Allegis failed because the name itself was not
popular.  Does anybody else see this happening to Airtouch?

Subject: 900 Numbers in California


Pacific Bell, which 'sells' regional (900) numbers has a brochure that
they send out to prospective users of the service. Here's a quote from
the brochure:

  " * California 900 Direct programs are assigned
       a specific telephone prefix based on the nature
       of their program content. The prefixes are:

       844   General Audience, recorded
               (including interactive).

       505   General audience, live (one-on-one and
                group-bridged services).

       303   Restricted adult material (live and recorded).
               Pacific Bell does not bill for programs on the
               303 prefix.

       * When you apply for service, you will be asked
          to select a prefix based on the content of your
          program.

       A telephone number that is easily remembered by your
       customers can be an effective marketing tool. If the number
       you want is available, we will honor your request. In most
       cases, a number installed for you in any Pacific Bell Service
       Area will automatically be reserved for you in all areas. If you
       start a program in only one Service Area, you may be able to
       expand to other areas using the same telephone number."

BTW, the connection charges, surcharges, and transport/billing fees
from Pacific Bell are ludicrously high. It's no wonder that most (900)
numbers are some kind of 'sex line' type of service. I can't see how
anyone else could afford to pay those fees (nothing sells like sex).
The biggest problem with running a (900) number (by FAR) is the amount
of bad debt in the industry. You've got to factor-in the fact that
between 30-50% of the people that call will never pay their bills
(Pacific Bell certainly doesn't make any mention of the fact).

Since you can not have your telephone service cut-off here for not
paying a (900) bill there is very little incentive for these (900)
callers to pay their bills.  Even though these people routinely will
not pay their bills (Pacific Bell does the billing on the local phone
bill) you will still be charged (as the 900 operator) ten cents or more
a minute for the billing, and that's for LOCAL calls. That doesn't of
course factor in the intra/inter lata charges which you are
responsible for if it's a long/short distance call (no intra-lata
competition in this part of California).

I imagine that other LEC's probably have a similar prefix 'code' for
different types of services.  I couldn't tell you whether the same
(900) number could be duplicated by someone else nationally and still
be available in a particular LEC area. Probably not.  This would
certainly cut-down the number of available numbers, if some of the
numbers are available only nationally, and some are only available
locally.

Subject: Need Textbook!


I am teaching telecommunications courses in the College of Business at
Bloomsburg University in Bloomsburg, Pennsylvania (undergraduate and
graduate).

I need to select textbooks for next summer and fall.

I have been examining the following textbooks:

TELECOMMUNICATIONS:  CONCEPTS, DEVELOPMENT, AND MANAGEMENT, by Blyth and
Blyth, Glencoe/McGraw-Hill, 1985  (This book includes the topics that I'd
like to cover, but does not include any cases.)

and

NETWORKS IN ACTION:  BUSINESS CHOICES AND TELECOMMUNICATIONS DECISIONS by
Keen and Cummins, Wadsworth., 1994 (This book includes cases but does not
cover the topics that I'd like to cover.)

The topics that I'd like to cover are as follows: History of Telecommun-
ications, Regulation, Telephony, Networks, Data Communications, Services,
Management, etc.)

Can anyone recommend another telecommunications textbook?  Please include
the title, author, publisher, and copyright date, if known.

Please send this information to [e-mail] (Internet).


Thanks,

The millions of dollars they spent to drive the name "Illinois Bell"

The heaviest element known to science is managerium. The element has
no protons or electrons but has a nucleus composed of one neutron, two
vice-neutrons, five assistant vice-neutrons, 25 pro vice-neutrons and
125 assistant pro vice-neutrons all going round in circles. Managerium
has a half-life of three years at which time it does not decay but
institutes a series of reviews leading to reorganization. Its
