Line Pools

All lines in a PRI interface are in the same PRI line pool. This
pool cannot contain any non-PRI lines. There is one PRI pool
available for each PRI interface on the CSU.
Depending on the order that the cards are configured as PRI,
Pool PRI-A represents lines 1 to 30, and Pool PRI-B represents
lines 31 to 60. If both PRIs are connected to the same service
provider and use the same protocol, lines 1 to 30 and 31 to 60
can be put in the same pool. There are four PRI pools available
for profile 1 and 4 systems, PRI-A, PRI-B, PRI-C, PRI-D
because these profiles support the off-core DTI module.

Programming Call by Call service selection

Programming the Norstar system for Call by Call Service
Selection with a PRI interface requires
• provisioning a PRI card if a PRI card is not already a part
of the system, on page 497
• selecting a protocol, on page 498
• programming incoming call routing, on page 499
• programming routes that use the PRI pools (under
Services), see Routing service on page 389

PRI Call by Call Limits

PRI pool limits for Call by Call services allows you to
configure limits for service types without interacting with the
CO. This feature sets the minimum and maximum number of
incoming and outgoing calls per service type for the PRI pool.
The number of active calls will be tracked so that whenever a
call is being set up, a check will be made to determine if it will
