Avaya 03-300430 User Manual

This test is destructive.

This test verifies the connectivity of a VC DSP 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. The Loopback test runs the following 
tests:

1. A loop-around test across the TDM bus.

2. A conference circuit test.

The tests are run in the above order; if one test fails, an Error Code is returned and the 
remaining tests in the sequence are not executed.

1000

1001

ABRT

System resources required to run this test are not available. The port may 
be busy with a valid call.

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

2012

ABRT

Internal system error

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

2100

ABRT

Could not allocate the necessary resources for this test.

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

0-3

FAIL

The NPE of the tested port was transmitting in error, causing noisy and 
unreliable connections.

1. Replace the circuit pack.

PASS

The port is correctly using its allocated time slots.

1. To be sure that this is not an intermittent problem, repeat this test up to 

10 times.

2. If complaints still persist, examine the station, connections, and wiring.
