m. Error Type 3840—Port Audit and Update Test (#36) failed due to an
internal system error. Enter status trunk command and verify the status of
the trunk. If the trunk is out-of-service, then enter release trunk command
to put it back to in-service. Retry the test command. If the test continues to
abort, then escalate the problem.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below 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.
NPE Crosstalk Test (#6)
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 usually only part of a port’s Long Test Sequence
and takes on the order of 20 to 30 seconds to complete.
