NPE Crosstalk Test (#9)
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. If a secondary data module is assigned, it is tested after the
primary data module. If either test fails, both data modules are taken out of service
This test usually runs only during the Long Test Sequence and takes about 20 to
30 seconds to complete.

Result Description/Recommendation
1 ABORT During testing of the primary information channel, system
resources may not have been available.
1. Check the port status. Use the display port PCSSpp
command to determine the station extension of the port. Use
the station status 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 this test. You must wait
until the port is idle.
2. If the port status is idle, then 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 busy with a valid call. Use the display port PCSSpp
command to determine the extension of the data module port.
Use the status data-module 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. (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 5 times.
1001 ABORT System resources to run this test are not available.
1. Retry the command at one-minute intervals a maximum of 5
times.
