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

for example, you may also clear errors generated from other tests
in the testing sequence.

NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) resides 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.
