System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the following table when
inspecting errors in the system. For example, by clearing error codes associated
with the Digital Port Sanity test (#565), you may also clear errors generated from
other tests in the testing sequence.
NPE Crosstalk Test (#9)
This test is a modified version of the Digital Line NPE Crosstalk test used by
DIG-LINE maintenance.
One or more Network Processing Elements (NPE) reside on each circuit pack
with a TDM-bus interface. The NPE controls port connectivity, 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/or noisy connections may be observed. This test is part of a port’s
long test sequence and takes approximately 10 to 20 seconds to complete. This
test is a modified version of the Digital Line NPE Crosstalk test used by DIG-LINE
maintenance.
