Descriptions and Error Codes
Always investigate tests in the order they are 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 about 20 to 30 seconds to complete.
