The following table lists area codes for San Jose, Monterrey, and Southern
California.
Call Scenario One
Site C can call San Jose using ISDN through one of two routes:
• Through the Site C gateway to the local phone system, making a long
distance connection, at a higher cost per minute.
• From Site C through the direct inter-site link to Site A and out its gateway,
at a lower cost per minute.
Call Scenario Two
Calls are frequently made from Site C to Los Angeles. The area codes for some
parts of Southern California are included in the LCR tables for Sites A and B,
because it is less expensive to make an intrastate long distance call within
California than an interstate long distance call from Washington, D.C. to Los
Angeles.
By including Southern California area codes in LCR tables for San Jose and
Monterey, if the bandwidth for the San Jose gateway is saturated, the call from
Site C can be routed through the Monterey gateway. The priority is to call from
Site A or Site B, because the LCR tables share a relative cost to dial the area
codes for Los Angeles.

Note
If you dial an area code that is not in an LCR table, the call goes through the
gateway from which the call originates.
