Subject: Service Outage ND and MN


Phone service to Moorhead, Minnesota and portions of Fargo, North
Dakota is still out after someone cut at least five different major
cables in the Fargo area over the weekend. Most of the service lost is
in Minnesota even though the cuts were in North Dakota. Some cables
were above ground, others were in manholes. Most were cut in several
places so simple splicing is not possible. Some of the cables were up
to five inches in diameter. Full service has been restored as of 
Tuesday
night to the Fargo area, with only 911 service and long distance 
service 
restored to Moorhead, full service is expected to be restored by 
Saturday.

Emergency services had cellular service available and instructed 
people 
needing assistance to go to the local fire stations or police stations
to seek help. I have not heard of any emergencies that were worsened 
due 
to this, but many areas in northwestern MN had no dial tone for 
several days.
I believe as many as 500,000 people were impacted by this at one time
or another.

The police and FBI are looking for a suspect in a burglary of a stereo
store from Saturday night where the alarm wires where also cut.

Initial suspicions were that it was someone with knowledge of the 
system 
due to the way things were damaged, however the current burglary 
suspect 
is not a past telco employee according to current reports.

I have seen articles indicating the LD carriers WilTel and US West (at
least in Phoenix area) forward CID information interstate.  Does
anyone know if the major LD carriers, notably AT&T, Sprint, & MCI,
foward CID information interstate?

As secondary questions, 

(1)  can anyone tell me if the areas of Louisville, KY and Cincinatti, 
OH
can send the CID information and 

(2)  whether Pennsylvania (that CID-fearful state) will accept the
information?  The Bell Atlantic person told me that PA switches 
suppress
CID information on INTER-LATA calls, but my understanding is that this 
is
only an outgoing suppression, not an incoming supression.  

Specifically, I'm interested in pinning down why I get an out-of-area
message on calls from Louisville, KY to my number in Pgh, PA. They use
MCI, I use AT&T.

Bezek has a cellular competitor -- they are like $0.03/minute in
Israel, which beats the pants off of Bezek.

I know these phones are selling well -- but I have been unable to find
people selling them!

I know that the venture is jointly done by Southwestern and Cellcom
(not the one is Wisconsin). So if I could get an e-mail address for
Southwestern Bell, I could track this down.

If anyone could help, it would be most appreciated.


Thanks,

You need the modem number for the paging company; usually it connects
at 300 or 1200 baud. At least for the system I use the pager ID is the
same as the phone number for the pager.

A MS-DOS program for paging is available from ftp.ripco.com:

        I must respectfully disagree with Pat on this.  Philco was a
big U.S.A. appliance company not connected, at least at that time,
with the Netherlands electronic giant N.V. Philips (not Phillips).
 
        "Philco" was formed from the company's original corporate
name, the Philadelphia Storage Battery Company, and was one of the
biggest manufacturers of radios in the 1930s and probably earlier.
Perhaps they got into radios as allied to their battery business,
since radios, at least home radio receiver, originally were all
battery operated.
 
        It is my recollection that they became a major player in the
television business because in the 1930s they acquired the rights to
the patents of Philo T. Farnsworth, who had invented a television
system entirely compatible with, but not the same as, the system
invented by Vladimir Zworkin, the RCA genius.  Farnsworth invented his
system at age 16 and was granted the key patent at age 22.  Some
commentators have suggested he has largely been dropped out of the
history of television because the idea that this callow youth could
have developed a system that worked as well as the system developed by
great corporate laboratories staffed with multiple Ph.D.'s is
inconsistent with the supposed value of extensive higher education and
big R&D expenditures, and the big embarrassment this caused RCA.
 
        Philco, I believe, was the only manufacturer that didn't have
to pay licensing fees to RCA, although I think they later reached a
cross-licensing agreement with RCA.
 
        Philips, the Netherlands company, was not very well known in
the United States before World War II.  During World War II, after the
Netherlands was occupied by Germany, their American operation became
separate under the name North American Philips Company, which used the
trade name Norelco.
 
        But Pat's description of the early television sets and how
they developed is right on the mark.
 
> Five digit numbers were common in communities which had automatic
> dialing systems in those days but only one exchange in the
> community. Since the exchange name was always the same, it was

> incorrectly. It was 8-2247, or to be complete about it, 
> ROckford-8-2247.
 
        I couldn't speak to the situation in Rockford, but I'm very
familiar with Oklahoma City, which had five-digit numbers for many
years, starting in 1920 when the "Northwest" office was put into
service as the first dial operation in the city (and the first central
office outside the downtown area).  The downtown office was all
manual, with exchanges Maple and Walnut (not MAple and WAlnut; they
were manual exchanges and you spoke their names to the operator).  The
manual numbers were the exchange name plus one, two, three or four
digits: Maple 5, or Walnut 4434.  Maple 5, for example, was not Maple
0005; it wouldn't have had any meaning in a manual exchange.
 
        The "Northwest" office (it's really part of the inner city
now) had five-digit numbers starting with 4, such as 4-1468.  But
there was no name associated with that; there was no toll dialing and
it was just 4-1468 in Oklahoma City; not Oklahoma City 4-1468.
 
        The downtown office was cut over to dial in 1928, using the
prefixes 2 and 3.
 
        Tulsa had a different history, and right up until the days of
2L-5N numbering (seven digits expressed as two letters and five
numerals) in the 1950s or 1960s, had four, five and six digits
numbers.
 
        In a small town I lived in (Konawa, Oklahoma, one of the first
CDOs in Oklahoma) the numbers were three and four digit.  My home
number was 287; office 234.  Four digit numbers there were party
lines; the central office was terminal per line and the fourth digit
selected the type of ringing.
 
        It's true that Bell companies usually recommended printing
five digit numbers as "8-2247," as Pat said, and six digit numbers as
"54-1468."  But it was variable; Dallas and Houston expressed their
numbers as, for example, Riverside-4085, which was dialed as R-4085.
But not too many telephones outside the largest metropolitan areas had
letters on the dial in those days.  And independent companies often
recommended displaying numbers in different ways, such as 8-22-47, or
82-247.
 
        "All Number Calling" (ANC) (seven numerals) came after the
2L-5N (two letter and five number) arrangement, usually in the 1960s
or thereabouts.
