Clearing trunk faults
Trunk faults
Trunk circuit cards provide the interface between the system and Central
Office (CO) trunks, or between PBXs. The maintenance telephone can be
used to test trunks. The Universal Trunk card provides four trunk units, each
of which can be connected to a trunk configured to operate as one of the
following:
•
Central Office trunk
•
Direct Inward Dialing (DID) trunk
•
Two-way Tie, Dial Repeating (2DR)
•
Two-way Tie, Outgoing Automatic Incoming Dial (OAID) trunk
•
Recorded Announcement (RAN) trunk
•
Music trunk
•
Paging trunk
Trunk faults can cause problems (such as noise) on outside calls and can keep
calls from entering or leaving the system.

symptom listed in this section that most resembles the fault indications and
go through the procedure for clearing each possible cause until the fault is
fixed. Once the fault is corrected, disregard the remaining possible causes.
Clear any power or Common Equipment faults before attempting to clear
trunk faults.
If the fault is not cleared after you have gone through each possible cause,
check the most recent fault indications. Also check
