11. The typical setup for the primary synchronization source is Active, and
other modules are set to Not Active. Under the Activation subheading in
each box, do one of the following:
12. Under the Channel Service Unit heading, check Foreign Exchange.
PRI Options
If the switch is part of a private network, the PRI options are automatically set. If
the switch is not part of a private network, then after you have completed the
module information on pages 1 and 2 of Form 3b, Incoming Trunks: DS1
Connectivity (100D Module), use the instructions in this section to record PRI
options:
Assigning B-channels to groups
Associating outgoing and incoming services to the groups
For groups with incoming services, selecting an incoming routing method
(Dial Plan Routing or Line Appearance) and providing routing information
For groups with outgoing services, completing the Network Selection,
Special Services, and Call-by-Call Service tables
Identifying the trunk and telephone numbers sent to the network for caller
identification
Assigning a test number used for maintenance by the service provider,
changing timers and counters from the defaults, and assigning the Terminal
Equipment Identifier (TEI)
All channels assigned to a group must be on the same 100D module. Also, the
order of the B-channel groups is not important. However, the order in which
channels are assigned within a group should be the exact opposite of the order in
which the telephone company's switch hunts through for a channel. Consult with
the service provider to determine what the correct order should be.
When programmed for PRI, the single DS1 jack on the 100D module supports 23
B-channels (the Channel 24 superframe transmits signaling mode information).
If loop clock synchronization is taking place, check Active (factory
setting).
If the clock is free-running, check Not Active.
