VC Summer Port Local TDM Loopback
Test (#1100)
This test is destructive.
This test verifies the connectivity of a VC Summer 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:
■ A Looparound test across the TDM bus.
■ A conference circuit test.
The tests are run in the above order. If the first test fails, the switch returns an
error code, and the second test is not executed.
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.
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 a
maximum of 10 times.
2. If complaints still persist, examine the station, connections, and wiring.
