3-1280WAE-PORT (Wideband Access Endpoint Port)
3
Notes:
a. The wideband acc ess endpoint has been b usied out by a busyout
access-endpoint <extension> command. No c alls can be mad e to this
extension.
b. The circuit pac k has been removed, or it has been in sane for more than 11
minutes. To clear the error, reinsert or replace the circuit p ack.
c. The Conference Circuit Test (#7) failed on this port. See Test #7 for repair
procedures.
d. The NPE Crosstalk T est (#6) failed on this port. See T est #6 for repair
procedures.
e. There was a failure of the TN464C UDS1 Interface circuit pack. See
UDS1-BD Maintenance documentation for d etails.
f. The Port Audit and Update Test (#36) failed due to an inter nal system
error. Enter the status access-endpoint <extension> command and
verify the status of the port. If the wideb and access end point is
out-of-service, enter the release access-endpoint <extension>
command to put it b ack to in-service. Retry the test comm and. If the test
continues to fail, escalate the p roblem.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order p resented in the table belo w when
inspecting errors in the system. By clearing error cod es associated with the
NPE
Crosstalk Test
, for example, you may also clear errors g enerated from other tests
in the testing sequenc e.
NPE Crosstalk Test (#6)
One or more Network Processing Elements (NPEs) reside on each circ uit pack
with a TDM Bus interface. (The TN464C UDS1 circuit pack has o ne
SCOTCH-NPE chip instead of several NPE chips). The NPE controls port
connectivity and g ain, and it provides c onferencing functions on a p er-port basis.
The NPE Crosstalk Test verifies that this port’s NPE channel talks on the selec ted
time slot and that it never crosses over to time slots reserved for other
