NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM Bus interface. (The TN464 UDS1 circuit pack has one SCOTCH-NPE
chip instead of several NPE chips.) 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 system resources to run this test or an internal system error
(software) occurred.
1. Retry the command at 1-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 status station or status trunk command to determine
when the port is available for testing.
1. Retry the command at 1-minute intervals a maximum of 5 times.
1001 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. The status health command can be used to determine if the
system is experiencing heavy traffic.
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.
1003 ABORT The system could not allocate a tone receiver for the test. The system may be
oversized for the number of Tone Detectors present or some Tone Detectors
may be out-of-service. The list measurements tone-receiver command will
display information on the system’s tone receivers.
1. Resolve any TTR-LEV errors.
2. Resolve any TONE-PT errors.
3. If neither condition exists, retry the test at 1-minute intervals a maximum of
5 times.
