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.

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.

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.
