General Programming in Networks
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
Pool Assignment
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, Chapter
4, "System Programming Procedures."
For 10xxx and 101xxxx equal access Interexchange Carrier (IXC), Dial 0, and N11
calls from a collocated 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 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.
!
CAUTION:
Unless 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.
