VC-SUMPT Port NPE Crosstalk Test (#6)
This test is destructive.
The NPE controls port connectivity and g ain and provides c onferencing
functions. The NPE Crosstalk test verifies that this port’s NPE channel talks on the
selected time slot and n ever crosses over to time slots reserved for other
connections. If the NPE is not working correc tly, one-way and noisy connections
may be observed. This test is p art of the port’s long test seq uence and takes
approximately 20 to 30 second s to complete.
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 port h ardware on the circuit pack .
The Loopback Test runs the following tests:
■A Looparound test across the TDM bus.
■A conference circui t test.

Code Test
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 for 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 pack.
PASS The port is correctly using its allocated time slots.
1. Verify that this is not an intermittent problem by repeating this test a
maximum of 10 times.
2. If complaints continue, examine the station, connections, and wiring.
