System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the following tables when
inspecting errors in the system. By clearing error codes associated with the NPE
Crosstalk Test, for example, you may also clear errors generated from other tests
in the testing sequence.
NOTE:
The NPE Crosstalk Test and the BRI Port Local TDM Loop Around Test are
not executed for ABRI-PORT/ATT-PORT/LGATE-PT/ATTE-PT.
NPE Crosstalk Test (#617)
This test is destructive.
One or more NPEs reside on each circuit pack with a TDM Bus interface. The
NPE controls port connectivity and gain and provides conferencing functions on a
per-port basis. 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, one-way and noisy connections
may be observed. This test is part of a port’s Long Test Sequence and takes
approximately 20 to 30 seconds to complete. Crosstalk testing is performed on
both B-channels (B1 and B2) associated with a BRI port. If this test fails on either
channel, any endpoints connected to the port are taken out-of-service.
