e. DS1 Interface circuit pac k detects a hardware error. The Aux Data field
contains the Error Type: 57474, rotary dial rate above 12 pu lses per
second; 57473, rotary dial rate below eight pulses p er second.
f. DS1 Interface circuit pac k detects a hardware error. The Aux Data field
contains the Error Type: 57392, no external release on PBX disconnect.
g. DS1 Interface circuit p ack detects a hardw are error. The Aux Data field
contains the Error Type: 57393, belated external release on PBX
disconnect.
h. DS1 Interface circuit pac k is out-of-service. Look for DS1-BD errors in
Hardware Error Log. Refer to the DS1-BD (DS1 Trunk Circuit Pack)
Maintenance documentatio n for details.
i. Error Type 2305—This error indicates that a signaling chang e was
detected by the PBX trunk circuit pack which is inc onsistent with the
present state of the trunk.
j. Port Audit and Update Test (#36) failed due to an internal system error.
Enter status trunk command to verify the status of the trunk. If the trunk is
out-of-service, then enter the release trunk comma nd to put it back to
in-service. Retry the test command.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order they are p resented in the table below when
inspecting errors in the system. By clearing error cod es associated with the
NPE
Crosstalk Test,
for example, you may also clear errors gene rated from other tests
in the testing sequenc e.
NPE Crosstalk Test (#6)
One or more NPEs reside on each circuit pac k with a TDM Bus interface. The
NPE controls port connectivity and gain, and provid es conferencing func tions on
a per-po r t basis. The N PE 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 correc tly, one-way and noisy connections
may be observed. This test is usuall y only part of a port’s Long Test Sequence
and takes about 20 to 30 sec onds to complete.
