NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) reside on each circ uit 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 g ain,
and provides c onferencing functions on a p er-port basis. The NPE Crosstalk Test
verifies that this port’s NPE channel talks on the selecte d time slot and never
crosses over to time slots reserved for other connec tions. If the NPE is not
working correctly, one-way and noisy connections may be ob served. This test is
usually only part of a port’s Lon g Test Sequence and takes about 20 to 30
seconds to comp lete

Error
Code Test
Result Description/ Recommendation
ABORT Could not allocate syst em resources to run this test or a n 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 alloc ate the necessary system resourc es 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.
