Avaya 03-300430 User Manual

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 

 in Maintenance Procedures 

(03-300192) 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.

●

Out-of-Service/Near-End (OOS/NE)

This is the state of the port when a hardware failure exists on the signaling link, the NPE 
Crosstalk test fails, or when the port is busied out by command. In this state, the port is 
unusable for calls coming into the switch or going out to the terminal adapter, although other
