VC DSP Port Local TDM Loop-Back Test (#1104)
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.
Table 8-708.

Result
Description / Recommendation
1000
ABORT
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
ABORT
Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
2100
ABORT
Could not allocate the necessary resources for this test.
1. Retry the command at 1-minute intervals up to 5 times.
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.
