e. DS1 Interface circuit pack detects a hardware error. The Aux Data field
contains the Error Type: 57474, rotary dial rate above 12 pulses per
second; 57473, rotary dial rate below eight pulses per second.
f. DS1 Interface circuit pack detects a hardware error. The Aux Data field
contains the Error Type: 57392, no external release on PBX disconnect.
g. DS1 Interface circuit pack detects a hardware error. The Aux Data field
contains the Error Type: 57393, belated external release on PBX
disconnect.
h. DS1 Interface circuit pack is out-of-service. Look for DS1-BD errors in
Hardware Error Log. Refer to the DS1-BD (DS1 Trunk Circuit Pack)
Maintenance documentation for details.
i. Error Type 2305
—
This error indicates that a signaling change was
detected by the PBX trunk circuit pack which is inconsistent 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
command 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 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 NPEs reside on each circuit pack with a TDM Bus interface. 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.
