PRI Options
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).
In the box that describes the 100D module providing secondary
synchronization, check Secondary.
In the box that describes the 100D module providing tertiary back
up, check Tertiary.
To retain the factory setting (that is, the system uses the clock of the
far-end connection), check Loop.
To change the setting (the clock is free-running), check Local.
If loop clock synchronization is taking place, check Active (factory
setting).
If the clock is free-running, check Not Active.
