Busy Verification of Terminals and Trunks
This feature allows attendants to place test calls to trunks, voice terminals, and hunt groups
(Direct Department Calling and Uniform Call Distribution groups). Busy Verification provides
an easy method of checking the condition of these facilities. When the feature is activated,
you can distinguish between a voice terminal or trunk that is truly busy and one that only
appears busy because of some trouble condition or because it was administered without
hardware.
The result of a busy verification test may be a display, tone, or conversation with the called
facility. In the following procedures, a successful verification tells you that the facility is
probably working properly; a failure tells you that the facility should be reported for
maintenance.
To busy verify a voice terminal:
1.
Press (Busy Verify).
• Busy Verify lamp lights steadily.
2. Dial the desired extension number.
• INVALID displayed, and intercept tone heard—invalid extension. Press
(Cancel), and try again.
• TERMINATED displayed, and ringback heard—called extension is idle and
ringing—verification is successful. Talk to the called party, or release from
the call.
• BRIDGED displayed—your call bridged onto an active call, and initial warning
tone was applied to the call—verification successful. Talk to the bridged
parties, or release from the call.
• OUT OF SERVICE displayed, and reorder tone heard—a trouble condition
exists at the terminal or it may apply to a terminal administered without
hardware and not be a trouble condition. Press (Cancel), and report the out-
of-service condition to appropriate personnel.
To busy verify a hunt group:
1.
Press
(Busy Verify).
Busy Verify lamp lights steadily.
2. Dial desired hunt group extension number.
• INVALID displayed, and intercept tone heard—invalid extension. Press
(Cancel), and try again.
