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 approximately 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.

ABORT
The port was seized by a user for a valid call. Use display port PCSSpp to
determine the trunk group/member number of the port. Use status trunk 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. Wait until the port is
idle before retesting.
1. If the port status is active but the port is not in use (no calls), check the
error log for error type 1025 (see the Error Log table for a description of
this error and required actions). The port may be locked up. Check the
CO wiring, check for excessive loop current, and check the trunk
translations. (If the trunk is translated incorrectly, this test will abort.)
2. If the port status is idle, busyout and release the trunk, and retry the
command at 1-minute intervals for a maximum of 5 times.
3. If the test still aborts, replace the circuit pack.

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.
