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
Loop
Around and Conference Circuit Test,
for example, you may also clear errors
generated from other tests in the testing sequence.
Notes:
a. ATMS test are not part of either sequence. They are run either on demand
with the test analog-testcall command or via the ATMS schedule.
NPE Crosstalk Test (#6)
One or more NPE 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 20 to 30 seconds to complete.
