NPE Crosstalk Test (#6)
One or more NPEs (Network Processing Elements) 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, 1-way and noisy connections may be observed. This test is
usually only part of a port's long test sequence and executes in about 20 to 30
seconds.

Code Result Description / Recommendation
1000 ABORT System resources required to run this test are not available. The port may be
busy with a valid call. This result is also reported for the system's
Music-on-Hold port when it is off-hook, which it usually is.
1. Enter display port UUCSSpp to determine the station's extension. Enter
2. When the port is idle, retry the command at 1-minute intervals up to 5
1001 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 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.
1. If the system has no TDM-BUS errors and is not handling heavy traffic,
2. If the test continues to abort, escalate the problem.
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. Resolve TTR-LEV errors.
2. Resolve TONE-PT errors.
3. Retry the test at 1-minute intervals up to 5 times.

port is active, it will be unavailable for certain tests. Wait until the port is
idle before retesting.
