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.
