NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and gain, and it 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 that it 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 it takes between 20 and 30 seconds to complete.

Result Description/Recommendation
ABORT System resources required for this test are not available.
1. Retry the command at one minute intervals a maximum of
5 times.
1000 ABORT System resources required to run this test are not available.
The port may be in use on a valid call. Use the status
access-endpoint <extension> command to determine when
the port is available for testing.
1. Retry the command at one minute intervals a maximum of
5 times.
2. If the test continues to abort, and if the port is not in use,
escalate the problem.
1001 ABORT System resources required for this test are not available.
1. Retry the command at one 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 that are out-of-service due to TDM-BUS errors. The
status health command can be used to determine if the
system is experiencing heavy traffic. Refer to TDM-BUS
Maintenance documentation to diagnose any active
TDM-BUS errors.
1. If system has no TDM-BUS errors, and if it is not handling
heavy traffic, repeat the test at one minute intervals a
maximum of 5 times.
