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.
