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 5, ‘‘Alarms, Errors, and Troubleshooting’’ for a layered
approach to addressing PRI endpoint problems.
In-Service (INS)
The B-channel is in its normal operating state.
Out-of-Service/Far-End (OOS/FE)
A B-Channel is initialized to this state when first administered. The switch
then sends messages to the far-end terminal adapter to negotiate the
B-channel into service. If the far-end terminal adapter does not respond to
the messages within a certain time period, the port remains out of service,
and maintenance will periodically resend the messages. The port is
unusable for incoming and outgoing calls, although other ports in the PRI
endpoint can still be used.
