OVERFLOW
When predefined overflow conditions are met, the system
automatically directs incoming calls to ring at a prepro-
grammed overflow extension.
Calls continue to ring at the attendant position as well, and
can be answered from either the overflow extension or the
attendant position.
Overflow conditions are met when:
• More than a defined number of calls are waiting in the
Main Call queue.
• A call has been waiting in the Main Call queue beyond
a defined time limit.
• The attendant activates night service while calls remain
in the Main Call queue.
When overflow occurs, the display shows OF followed by
the number of calls waiting (instead of CW).
When the overflow condition ceases to exist, normal oper-
ation is resumed.
