NPE Crosstalk Test (#6)
One or more Network Processing Elements (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 Could not allocate the necessary system resources to run this test.
1. Retry the command at one-minute intervals a maximum of five times.
1000 ABORT System resources required to run this test are not available. The port may
be busy with a valid call. Use the display port PCSSpp command to
determine the station extension. Use the status station command to
determine the service state of the port. If the service state indicates that
the port is in use, the port is unavailable for certain tests. (Refer to the
"Status Commands" section in Chapter 8, "Maintenance Commands and
Trouble-Clearing Aids", for a full description of all possible states.) You
must wait until the port is idle before retesting.
1. If the port status is idle, retry the command at one-minute intervals a
maximum of five times.
1001 ABORT System resources required to run this test are not available. This could be
due to a failure to seize the port.
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 one-minute intervals a maximum of five times.
