First, for those not familiar with the area, 408 is really two planets: northern and southern. The northern part, which includes San Jose and the Silicon Valley is considered part of the Greater Bay Area and is part of the San Francisco LATA which includes all of 415 and all of 707. The southern part (to the south of the Santa Cruz mountains) is mostly in the Monterey LATA (except Santa Cruz and Watsonville) and is a completely different animal. There are no N0X/N1X prefixes anywhere within 408. In the north (SF LATA) 408 telephones do not dial "1" for long distance. The CO switches determine 7/10 digits from the number being dialed. There is also no delay time out. If the number begins with an NPA the exchange expects 10d. Otherwise the call is handled accordingly. My particular CO will absorb a "1", but it is not required. It will not accept a "1" for a call within 408. As of this evening, my CO will accept either 0+7D or 0+NPA+7D for calls within 408. This applies to calls in either SF or Monterey LATA. Calls that terminate in the Monterey LATA get the KaBong followed by "AT&T". For what it's worth, my CO switch is an ANCIENT 1ESS (probably the skankiest switch in San Jose other than the grossbar.) South of the Santa Cruz mountains, a "1" IS required for long distance. I don't know how 0+ calls are handled. Someone from UC Santa Cruz could maybe fill us in? John Higdon | P. O.
