VC-SUMPT Port NPE Crosstalk Test (#6)
This test is destructive.
The NPE controls port connectivity and gain and provides conferencing functions.
The NPE Crosstalk test verifies that this port's NPE channel talks on the selected
time slot and never crosses over to time slots reserved for other connections. If
the NPE is not working correctly, 1-way and noisy connections may be observed.
This test is part of the port's long test sequence and takes approximately 20 to 30
seconds to complete.

Error Test
Code Result Description / Recommendation
1000 ABORT System resources required to run this test are not available. The port may be
1001 busy with a valid call.
1. Retry the command at 1-minute intervals up to 5 times.
2012 ABORT Internal system error
2100 ABORT 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. This causes noisy and
unreliable connections.
1. Replace circuit pack.
PASS The port is correctly using its allocated time slots.
1. Verify that this is not an intermittent problem by repeating this test up to 10
2. If complaints continue, examine the station, connections, and wiring.
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 Loop-Around test across the TDM bus.
A conference circuit test.
