This section outlines system features and programming options that may need adjustment or special planning when your system is included in a private network. This section includes the following topics:

Pool Assignment

Automatic Route Selection (ARS)

Remote Access without Barrier Codes

Clock Synchronization

System Date and Time

Tie Trunks

Direct Inward Dialing (DID) Trunks

For Release 6.1 and later, calling groups used for coverage to a non-local extension or calling group to route calls to centralized VMS/AA, non-local QCC, or other non-local facilities

Pool Assignment

5

All tandem trunks must be assigned to pools. If tandem PRI trunk pools are available, these should be assigned to Route 1 in UDP patterns. For programming procedures, see “Trunks to Pools Assignment” in System Programming.

For 10xxx and 101xxxx equal access Interexchange Carrier (IXC), Dial 0, and N11 (for example, 411 or 911) calls from a collocated private networked system that is not connected to the PSTN, the tandem trunks must be assigned to the main pool so that these calls can be routed across the private network to another system’s public switched telephone network (PSTN) trunks. For equal access calls, the system automatically prepends the local ARS access code, which must match the ARS code of the non-local system. For Dial 0 and the Special Numbers table, the ARS code must be prepended.

!CAUTION:

Unless private networked systems are collocated, each system should have at least one loop-start line connected to the PSTN. The line is required to allow connection of a power-failure telephone to the Power-Failure Transfer (PFT) jack on a module as a power outage backup and for correct routing of emergency and other N11 calls. To ensure that the correct services are reached, if the loop-start line is used for emergency or other N11 calls, it should be assigned to the main pool. In this case, IXC calls determine the number of loop-starts required. Refer to Feature Reference guide for details on the PFT feature.
