System Technician-Demanded Tests:
Descriptions and Error Codes
Investigate tests in the order presented below. Clearing Error Codes associated with the one
test may also clear errors generated from other tests in the sequence.
Note:
Note: For TN767B vintage 8 or 9 circuit packs, a failure of Test #136 causes a
subsequent failure of Test #7. Test #136 is part of the short sequence and
generates off-board alarms Test #7 is part of the long sequence and generates
on-board alarms. Before entering busyout, release, reset or test board
location long commands, check the vintage number of the circuit pack with
list configuration board location. If it is TN767B vintage 8 or 9, do
not use the above commands until first making sure that Test #136 passes using
test board location short. Otherwise, extraneous on-board alarms may
be generated.
NPE Crosstalk Test (#6)
Note:
Note: S8500 / G700: This test aborts with Error Code 1412 on the G700.
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, 1-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.
