Routing Patterns — ISDN-PRI Applications

NOTE: The ROUTING PATTERN screen only relates to outgoing calls; page 2 of the TRUNK GROUP screen only relates to incoming calls.

A routing pattern is a set of trunk groups that carry calls to a particular switch. Each routing pattern is identified by a unique number known as the pattern number. A maximum of 254 different patterns may be administered. Each pattern may contain up to six different trunk groups (six alternate trunk routes). Once a routing pattern is accessed the call processing software will, depending on trunk group compatibility (both FRL and BCC) and trunk member availability, select the trunk groups in decreasing order of preference (that is, 1, 2,...6).

NOTE: Both ISDN-PRI private networks and ISDN-PRI public networks require that one or more ROUTE -PATTERNscreens be administered. For private networks, the RNX tables must be translated. Each RNX table serves as a pointer to one or more pattern numbers. For public networks, the appropriate HNPA, FNPA, and/or RHNPA tables must be translated. These tables serve as a pointer to one or more different pattern numbers.

Figure 7-78,Routing Patterns Screen, depicts this procedure.
