m. Error Type 2817—Glare error. This error is logged only. It is not a
hardware failure and hence does not start any testing or generate any
alarms. This error is the result of a simultaneous seizure of a two-way trunk
from both the near-end and the far-end. Attempt to place the call again. If
the error persists, execute the Dial Tone Seizure Test (#314) and follow
those procedures.
n. Error Type 3840—Port Audit and Update Test (#36) failed due to an
internal system error. Enter the status trunk command to verify the status
of the trunk. If the trunk is out-of-service, then enter the release trunk
command to put it back into in-service. Retry the test command. If the test
continues to abort, then escalate the problem.
System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order they are 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) resides 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.
