Call Waiting indicator
The Call Waiting indicator indicates that there is a queue of calls to be
answered. When one or more calls are waiting, "CW" appears on line 4 of the
display. The CW display changes from steady to flashing when waiting calls
exceed a certain number or when a call has been waiting longer than a
specified time.
The maximum number of waiting calls and the maximum hold time for each
waiting call to be answered can be set with a data administration task. Refer
to Features and Services (553-3001-306) for more information.
An optional buzz is available to indicate when the first call enters the queue.
The number of waiting calls can be viewed on the LCD screen by pressing a
key assigned on the attendant console. On the M2250, the number of waiting
calls can be displayed continuously on line 4 of the display, if defined in
LD15 and selected from the Options menu.
Alarm indicators
Alarms appear on line 4 of the display. "MN" indicates a minor alarm
condition; "MJ" indicates a major alarm. A minor alarm is an indication of a
minor system failure affecting a limited number of lines or trunks. A major
alarm indicates that Emergency Transfer may have been initiated. See
"Emergency Transfer" on
Emergency Transfer
If a major equipment or power failure halts local call processing, preselected
CO trunks are automatically connected to preselected stations (predetermined
and hard-wired at installation time) through relays in the system. Emergency
Transfer can also be activated manually by a switch underneath the attendant
console.
