Pri Routing Protocols; Using Destination Codes - Nortel BCM50 Configuration Manual

The service identifier (SID) depends on the selected service type (for example, with
NI-2 protocol).

a. For NI-2, do not program the Carrier Access Code for banded OUTWAT calls. This call may be
rejected.
When you select or change a PRI protocol, the Service Type and Service ID fields automatically
clear for each entry in the routing table for that PRI.

Using destination codes

Destination codes allow you to control how the system interprets and routes dial strings from
internal sources. Destination codes are similar to line pool codes except that by using routes
(which attach dial strings and DN type designators to line pools) and schedules you can control
what digits the user has to dial and how the system routes the call out of the system, including what
numbers from the dial string get added or deleted to the route dialout.
