CHAPTER 8. TROUBLESHOOTING PROCEDURES FOR VOICE TERMINALS
Trunk Group Busy/Warning Indicators
This feature provides the console attendant with a visual indication of the trunk group status
for each of the console Trunk Group Select buttons.
Twelve of the Trunk Group Select buttons have associated WARNING and BUSY
other 12 buttons have only associated BUSY lights. The lights function as follows:

lights can alert you to unusual or suspicious conditions such as groups that are
always busy or never busy. Knowing what hours of the day are the most busy, and the least
busy in terms of trunk usage is also useful in analyzing possible trunk problems. For
example, if the BUSY light for a particular group is on during a normally slack period, you
should check the possibility that one or more trunks is really out of service, but appears to
be busy. On the other hand, a trunk group BUSY light that never goes on should also be
checked. Use the Busy Verification feature to test suspected faulty trunks.
Other Maintenance Tips
Complaints from telephone/voice terminal users that they are not receiving calls sometimes
result from accidental operation of the Send All Calls button or failure to cancel Call
Forwarding. In response to such a complaint, place a call to the voice terminal user and see
if a
f or s appears on the display. If either of these codes is displayed, tell the user to
deactivate the feature.
System Parameters
The System Manager can use the System Management Terminal (SMT) (System 85) or
DEFINITY Manager™ II (Generic 2) to monitor system conditions that may reflect troubles
reported by users. Three action/object/qualifier commands are especially useful in this
respect:
◆ Status commands can be used to check the status of stations, trunks, data modules,
and links. For example, status station for a particular extension number shows
whether Call Forward and Send All Calls are currently activated.
