Descriptions and Error Codes
Always investigate tests in the order p resented in the table below when
inspecting errors in the sy stem. By clearing error cod es associated with the
NPE
Crosstalk Test
, for example, you may also clear errors g enerated from other tests
in the testing sequenc e.
For TN767B vintage 8 or 9 circuit pac ks, 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 g enerates
on-board alarms. Before entering busyout, release, reset or test board long
commands, chec k the vintage number of the circ uit pack with list configuration
board UUCSS. If it is TN767B vintage 8 or 9, do not use the above comm ands
until first making sure that Test #136 passes via test board short. Otherwise,
extraneous on-board alarms may b e generated.
NPE Crosstalk Test (#6)
The NPE Crosstalk Test verifies that this port’s NPE channel talks on the se lected
time slot and never crosses over to time slots rese rved for other connections. If
the NPE is not working correctly, one-way and noisy connec tions may be
observed. This test is usually only pa rt of a port’s Long Test Sequence and takes
on the order of 20 to 30 seconds t o complete.
