VC DSP Port Local TDM Loopback 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 indic ates an
on-board fault associated with the port hardware on the c ircuit pack. The
Loopback Test runs the following tests (refer to Figure 3-51):
1. A looparound test across the TDM bus.
2. A conference circ uit test.
The tests are run in the above order; if one test fails, an error c ode is returned
and the remaining tests in the seq uence are not executed.

Result Description/ Recommendation
1000
1001 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 a maximum of 5 times.
2012 ABORT Internal system error
2100 ABORT Could not allocate the necessary resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
0-3 FAIL The NPE of the tested port was transmitting in error. This causes noisy and
unreliable connections.
1. Replace circuit pac k.
PASS The port is correctly using its allocated time slots.
1. To be sure that this is not an intermittent problem, repeat this test a
maximum of 10 times to make sure that it continues to pass.
2. If complaints still persist, examine the station, connections, and wiring.
