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
ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1000 ABORT System resources required to run this test were not available.
The port may be busy with a valid call. Use the display port PCSSpp
command to determine the trunk group/member number of the port. Use
the status trunk 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 active but the port is not in use (no calls), check the
error log for error type 1025 (see the Error Log table for a description of
this error and required actions). The port may be locked up.
2. If the port status is idle, retry the command at 1 minute intervals for a
maximum of 5 times.
1001 ABORT System resources required for this test are not available.
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 error. 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.
