2 Call-Handling Scenarios
Network Configuration Scenarios	Page 2-60

■System J does not require ARS toll-saving calling for all local system users to outside facilities connected to System L.

■A series configuration such as this one requires two tandem PRI facilities for the systems that connect to two other systems, in this case Systems K and L. This means that fewer outside facilities can be connected to these systems than to Systems M and J because the system’s capacity of 80 lines/trunks (or three DS1 facilities) cannot be exceeded. Compare the outside facilities with those of Scenario 4 shown in Figure 2–5 on page 2–75.

■In this series configuration, System L has centralized VMS/AA to serve Systems K and M respectively. Systems K and M are programmed for patterns that select pools that route to the centralized VMS/AA on the System L. System J does not have coverage to the centralized VMS/AA System L because it has its own VMS/AA and it is not possible to cover calls over more than one span between sender and receiver on the private network.

■Some calling groups on Systems K and M are configured to overflow to the centralized VMS/AA on System L, in the event that all extensions in a calling group are busy. If the overflow threshold or timeout is reached, the call will be routed to the centralized VMS/AA, at which point the caller may leave a message in the calling group’s mailbox.

■Some calling groups on System J are configured to overflow to the QCC queue on System K. To route calls to the QCC at System K, a local calling group with a single non-local member must be created at System J. This non-local calling group member is the extension for the QCC queue (Listed Directory Number) at System K.
