Descriptions and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. For example, by clearing error codes associated with the
NPE Crosstalk test (#6), you may also clear errors generated from other tests in
the testing sequence.
Order of Investigation
NPE Crosstalk test (#6)
Conference Circuit test (#7)
DS1 OPS Switchhook Inquiry test (#312)
Audit and Update test (#36)
1. D = Destructive; ND = Nondestructive
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.

Error Test
Code 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 up to 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 up to 5 times.
1001 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
