NPE Crosstalk Test (#6)
One or more NPEs 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 about 20 to 30 seconds to complete.

Result Description/Recommendation
1000 ABORT System resources required to run this test are not available.
The port may be busy with a valid call. Use the display port
PCSSpp command to determine the station extension. Use
the status station command to determine the service state of
the port. If the service state indicates that the port is in use,
then the port is unavailable for certain tests. You must wait
until the port is idle before retesting.
1. If the port status is idle, then retry the command at
1-minute intervals a maximum of 5 times.
1001 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
1002 ABORT The system could not allocate time slots for the test. The
system may be under heavy traffic conditions or it may have
time slots out-of-service due to TDM-BUS errors. Refer to
“TDM-BUS (TDM Bus)” Maintenance documentation to
diagnose any active TDM-BUS errors.
1. If system has no TDM-BUS errors and is not handling
heavy traffic, repeat test at 1-minute intervals a maximum
of 5 times.
