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

until first making sure that Test #136 passes via
test board short
. Otherwise,
extraneous on-board alarms may be generated.
NPE Crosstalk Test (#6)
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
on the order of 20 to 30 seconds to complete.
