Avaya 03-300430 User Manual

This test is destructive.
This test verifies the connectivity of a BRI port across the TDM Bus.  It aborts if calls associated 
with the port are in progress.  Failure of this test indicates an on-board fault associated with the 
port hardware on the circuit pack.
This Loop Around test runs a series of individual tests on the two B channels (B1 and B2) 
associated with the port.  It is a collection of the following:

●

Loop Around test across the TDM Bus for B1.

●

Conference Circuit test for B1.

●

Loop Around test across the TDM Bus for B2.

●

Conference Circuit test for B2.

The tests are run in the above order.  If one fails, the remaining tests in the sequence are not 
executed.  An error code is returned at that point.
This test is not executed for ABRI-PORT/ATT-PORT/LGATE-PT/ATTE-PT because the B 
channels associated with the port are not used by ASAI or Avaya adjuncts.

ABRT

Internal system error.

2100

ABRT

Could not allocate the necessary system resources to run this test.

1. Retry the command at 1-minute intervals up to 5 times.

2. If the test continues to abort, escalate the problem.

FAIL

The Loop Around test has failed.

1. If the test fails repeatedly, attempt to reset the circuit pack if the other 

ports on the board are idle.  Reset the circuit pack by issuing the 
busyout board location and reset board location.

2. If the test fails again, execute test port-network pn#.  If this fails, 

follow failure procedures in 

3. If tests executed in step 2 pass, the problem is local to the BRI board.  

Replace the circuit pack.

PASS

The BRI Port Local LAN Loop Around test has passed.
