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. Stephen Grove Comm. Tech. ESS Pac Bell Sonoma County, Calif

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.")

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.
