Notes:
a. Error Type 1—Aux Data 57408—No tip ground is d etected on an outgoing
call.
Aux Data 57487—PBX could not get "loop close" signal (TN767).
The DS1 Interface circuit pack detected a hardware fault. These errors
cause the Dial Tone Test (#314) to run and are only considered a problem
if the Dial Tone Test fails (in which case Error Type 1025 also shows up). In
this case, the trunk may be pu t in ready-for-service state (shown as
"disconnected" by status c ommand), which allows only inc oming calls.
Run the Dial Tone Test (#314) and follow its outlined proc edures.
b. Error Type 15—This is a software audit error that does not indicate any
hardware malfunction. Run Short Test Sequence and investigate
associated errors (if any).
c. Error Type 18—System Technician has busied-out the trunk to the
out-of-service state. No calls c an be made on this trunk exc ept the Facility
Access Test Call.
d. Error Type 130—This error type indicates that the circuit p ack has been
removed or has been insane for more than 11 minutes . To clear the error,
reinsert or rep lace the circuit p ack.
e. Error Type 257—The DS1 Interface circuit pack d etects a hardware fault.
The Aux Data field contains the following error type: 57392—no external
release on PBX disconnect [E030]. Escalate the p roblem.
f. Error Type 513—The DS1 Interface circuit pack detec ts a hardware fault.
The Aux Data field contains the following error type: 57393—belated
external release on PBX disconnect [E031]. Escalat e the problem.
g. Error Type 769—The DS1 Interface circuit pack detects a hardware fault.
The Aux Data field contains the following error type:—57484, fault is
detected on tip /ring [E08C]. Escalate the error.
h. Error Type 1793—DS1 Interface circuit pack is out-of-servic e. Look for
DS1-BD errors in the Hardware Error Log. Refer to the DS1-BD (DS1 Trunk
Circuit Pack) Maintenance doc umentation for details.
i. Error Type 2562—Retry Failure error. This error is logged onl y. It is not a
hardware failure and hence d oes not start any testing or generate any
alarms. This error comes from call proc essing and is generated when a
second attempt (retry) to seiz e an outgoing trunk fails.
j. Error Type 2817—Glare error. This error is logged only. It is not a hardware
failure and hence does not star t 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 c all again. If the error
persists, execute the Dial Tone Seizure Test (#314) and follow those
procedures.
