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 assoc iated with the port are in prog ress. Failure of this test
indicates an on-board fault associated with the p ort hardware on the circuit p ack.
The Loopback Test runs the following tests (refer to Fig ure 3-5 3):
■A Looparound test across the TDM bus.
■A conference circui t test.
The tests are run in the above order. If the first test fails, the switc h returns an
error code, and the sec ond test is not executed.

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 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.
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.
