Avaya 03-300430 User Manual

This nondestructive test performs a far-end loop-around test over an ATM-BCH trunk if:

●

The trunk is IN-SERVICE, MAINTENANCE/NEAR-END, or OUT-OF-SERVICE/
NEAR-END.

●

No calls are active on the trunk.

●

The system uses country protocol 1 (including US), or the far end has loop-around 
capability.

The test sets up a call to a far-end switch over the ATM-BCH trunk.  Then the digital port on a 
TN711D Maintenance/Test circuit pack sends a bit pattern to the far end and back.  If the 
received pattern matches that sent, the test passes.  If there are differences, it fails.

You can initiate a synchronous outgoing test call (including a test call for ISDN-PRI trunks) with 
these commands:

●

test trunk grp#/mem# long (repeat#)

●

test board location long (repeat#)

●

test port location long (repeat#)
