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.

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 the display
port PCSSpp command to determine the trunk group/member
number of the port. Use the status trunk 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. You must 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
then 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
