[comp.dcom.telecom] Telebit vs. Sprint

seg@pacbell.com (S. E. Grove) (05/26/90)

Pac Bell has a dial up distribution network that they have called
PacNet. But the fiber optic network for internal company use only, is
call PBNet. The reason for the internal company use only is that we
are not allowed to switch calls interlata, except for ourselves.  If
AT&T sent a message over PacNet to Pac Bell it would most likely
travel on PBNet.

I must disagree, regionally.  Like most telecommunications services
that belong to companies headquartered on the east coast, MCI has
followed the unfortunate pattern of making the West last.

As a former MCI employee in National Accounts, I can tell you that on
the east coast, MCI connection are as good if not better than Sprint
and/or AT&T. The reason for this is simple: MCI deployed their fiber
and digital switches primarily in the Northeast corridor.

MCI only has four major points at which calls are actually "switched"
with the balance of their terminals simply acting as repeaters or pass
throughs to one of the four switching centers.  MCI had more
subscribers per unit area on the east coast, and being a company hq'ed
there, chose to make the majority of the "digital" investment there.

I can still remember the analog microwave that was in service in
California.  Typical of being left to last, there was supposed to be
only something like 30 miles between each repeater.  Unfortunately,
MCI ran out of resources and so there was something more like 80 miles
between instead.  Every time the fog rolled in near San Jose, there
went the connections between LA and SF.  In fact, one engineer figured
that the signal was actually bouncing off the ground in between
repeaters.

Although there is fiber on the the California acquaduct, it is used
primarily for private line, DDS and the State of Calif.

There is supposed to be digital microwave from Richardson TX to the
west coast (Richardson is one of the four magic points), but I have
yet to get a digitial connection from Texas.

Out here, MCI is definetely not as good as Sprint or AT&T, but out
east it is as good technically.

(As a side note about the west getting features last, you might recall
an article that appeared here recently under the heading of "A piece
of ESS history." The article pointed at a 1965 ESS deployment of an
ESS machine *with* custom calling features available.  Althought the
first ESS was also deployed in LA in 1965, it wasn't untill about 1977
that custom calling was offered.  At least that was the first year we
were able to offer it to customers - I was also a Pac Bell service
rep.  --Excuse me, "Pacific Telephone.")

That's odd. I remember the first Bay Area ESS cuts as being around the
very early '70s. (I started noticing the "precise" ringback tone, and
the funny way when someone answered, the RBT would stop almost a full
second before there was the clunk of the audio path being completed.)
Anyway, it was not more than a year before the first basic features
were offered: three-way, forwarding, and call-waiting. Speed calling
didn't become available until something like 1976, but there were
definately the other features available years before that.

This is extra odd, since it has been my experience that ALL
technological improvements in Pac*Bell (or Pacific Telephone,
depending on the era) come to the Southland years before anywhere else
in the state, including the Bay Area.
