*Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the appropriate test description and follow the recommended procedures.

Major alarms on this MO may be downgraded to Warning alarms based on the value used in the set options command. If the Minor alarm is not downgraded by the set-options** values, the Minor alarm is upgraded to a Major alarm if 75 percent of the trunks in this trunk group are alarmed.

Notes:

(a) These are in-line errors that have no specific test associated with them. Refer to the following Table 27 for an explanation and appropriate action.
(b) This is a software audit error and does not indicate any hardware malfunction. Run the Short Test Sequence and investigate associated errors.
(c) Aux data 57376--No loop current on incoming call

Aux data 57424--No loop current on outgoing call

These errors cause the Dial Tone Test (#0) to run and are only considered a problem if the Dial Tone Test fails (in which case Error Type 1537 also appears). In this case, the trunk may be put in ''Ready-for-Service'' state (shown as ''disconnected'' by status command), which allows only incoming calls. Run the Dial Tone Test (#0) and follow its procedures.

(d) Single polarity ringing current--This error results from abnormal ringing current, but does not prevent the incoming call from being accepted. This error code is logged for information purposes only and does not cause additional testing to occur.
(e) Late CO Trunk release--This indicates that the CO releases the trunk at least four minutes after the PBX dropped the call. This error code is only logged as an informational event and causes no other testing to occur.
(f) Dial-Tone Test

Table 27. DIOD Trunk Errors without Associated Tests �
Error Type	Aux Data	Description and Recommendation
769	57392	CO not releasing after call is dropped from PBX. After several occurrences, an off-board warning alarm is generated. Refer problem to CO.
2561	57345	Single polarity ringing current. This error results from abnormal ringing current, but does not prevent the incoming call from being accepted. One cause could be that the reverse current detector associated with the port is failing. (Will not be detected by any tests.) The other cause could be that normal current is not detected. In this case, neither incoming nor outgoing calls can be completed, and the dial tone test also fails. Check for other errors.
2817	57393	CO released the trunk at least four minutes after the PBX dropped the call. This error code is log only and causes no other testing to occur. No alarm is generated. Check for other errors.
3073	57376	No loop current on incoming call. The incoming destination has already answered and no loop current has been detected. If this is a hard fault, the dial tone test and all outgoing calls should also fail. Check for other errors.
3585	57424	No loop current on outgoing call. This error occurs on attempt to seize a loop or ground-start trunk for an outgoing call. An error occurs if loop current is not detected or the caller hangs up before it is detected. Busyout the affected port, and run a Long test. If Dial Tone Test #0 passes, ignore this error. Release the port.
