PE-BCHL (PRI Endpoint Port)
Issue 1 May 2002
8-1215
555-233-143
A PRI endpoint port is a port on a UDS1 interface circuit pack and thus depends
on the health of the circuit pack for proper operation (see the following figure). A
problem on the associated ISDN-LNK’s (ISDN-PRI signaling-link port’s) D channel
can also affect the PRI endpoint. In turn, the ISDN-LNK depends on the
SYS-LINK (system link) to the packet interface. Keep this hierarchy of
dependencies in mind when diagnosing problems.

PRI Endpoint Port Interactions
PRI Endpoint Port Service States
The status pri-endpoint extension command displays the following possible
service states for PRI endpoint ports. The table that follows gives recommended
procedures for each state. The figure following that shows typical progressions
from one service state to another. Refer also to Troubleshooting Wideband
Problems in
Chapter 4, ‘‘Alarms, Errors, and Troubleshooting’’
approach to addressing PRI endpoint problems.
