Other alarms can be diagnosed by using the short and/or long test sequences.
Note that a PRI Endpoint Port B-channel can be placed into a Far-End Service
State either by direct action of the far-end terminal adapter or by inaction of the
far-end terminal adapter. For example, if they do not respond to a Remote Layer
3 Query (see Test #260 for ISDN-PRI Signaling Link Port), the associated PRI
Endpoint Port B-channels are placed into the Maintenance/Far-End service state.

A PRI Endpoint Port is a port on a UDS1 interface circuit pack. Therefore, this
port depends on the health of the UDS1 interface circuit pack for proper
operation (see

). As noted earlier, a PRI Endpoint Port B-channel
also depends on an ISDN-PRI Signaling Link Port D-channel (ISDN-LNK) to carry
the signaling traffic. If there is a problem with the ISDN-PRI Signaling Link Port,
the PRI Endpoint Port is affected. The ISDN-PRI Signaling Link Port, in turn,
depends on the PI-LINK (Processor Interface Link). Processor Interface Link
problems affect the ISDN-PRI Signaling Link Port. Keep this hierarchy of
dependencies in mind when diagnosing problems.

PRI Endpoint Port Service States
This section defines the possible service states of a PRI Endpoint Port, and it
explains the reason for each service state. This section also provides the
recommended recovery procedures (when required).
