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.
NPE Crosstalk Test (#6)
Loop Around and Conference Circuit Test (#33)
Tie Trunk Seizure Test (#73)
Test (#747)
Tie Trunk EPF Test (#74)
Port Audit and Update Test (#36)
Update Test (#36)
Analog Transmission Test (#844-848)
1. D = Destructive; ND = Nondestructive
2. Non-TN439 and non-TN497 circuit packs only
3. TN439 circuit pack only
4. TN497 circuit pack only
5. G3iV1.1-286 and G3iV2-386 only
6. Non-TN497 circuit packs only
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.
