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 occur. 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 Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1000 ABORT System resources required to run this test are not available. The port may
be busy with a valid call and therefore unavailable for certain tests. You
must wait until the port is idle (yellow LED if off) before retesting.
1. If the port is idle, 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.
1003 ABORT The system could not allocate a tone receiver for the test. The system may
be oversized for the number of Tone Detectors present or some Tone
Detectors may be out-of-service.
1. Look for TTR-LEV errors in the Error Log. If present, refer to TTR-LEV
(TTR Level) Maintenance documentation.
2. Look for TONE-PT errors in the Error Log. If present, refer to TONE-PT
(Tone Generator) Maintenance documentation.
3. If neither condition exists, retry the test at 1-minute intervals a
maximum of 5 times.
1004 ABORT The port was seized by a valid call during the test and the test has been
aborted. You must wait until the port is idle (yellow LED if off) before
retesting.
1. Retry the command at 1-minute intervals a maximum of 5 times.
