Notes:
a. The wideband access endpoint has been busied out by a busyout
access-endpoint <extension> command. No calls can be made to this
extension.
b. The circuit pack has been removed, or it has been insane for more than 11
minutes. To clear the error, reinsert or replace the circuit pack.
c. The Conference Circuit Test (#7) failed on this port. See Test #7 for repair
procedures.
d. The NPE Crosstalk Test (#6) failed on this port. See Test #6 for repair
procedures.
e. There was a failure of the TN464C UDS1 Interface circuit pack. See
UDS1-BD Maintenance documentation for details.
f. The Port Audit and Update Test (#36) failed due to an internal system
error. Enter the status access-endpoint <extension> command and
verify the status of the port. If the wideband access endpoint is
out-of-service, enter the release access-endpoint <extension>
command to put it back to in-service. Retry the test command. If the test
continues to fail, escalate the problem.

Descriptions and Error Codes
Always investigate tests in the order presented in the table below when
inspecting errors in the system. By clearing error codes associated with the
NPE
Crosstalk Test
, for example, you may also clear errors generated from other tests
in the testing sequence.
NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) reside on each circuit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has one
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and gain, and it provides conferencing functions on a per-port
basis. The NPE Crosstalk Test verifies that this port’s NPE channel talks on the
