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 Figure 3-38
). 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 PKT-INT (Packet Interface).

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).
Service States
■ In-Service (INS)
The B-channel is in its normal operating state.
