When the number of calls waiting for a secondary announcement multiplied by the
length of that announcement is greater than the announcement interval, an alarm
is triggered.
Alarm button would or would not indicate a problem.
If problems arise, use the display at the calling group supervisor DLC console to
monitor the situation while the problem is most severe. Try to adjust the
announcements' durations and the interval setting so that the announcement
interval is greater than or equal to the length of the secondary announcement
multiplied by the number of calls waiting for the secondary announcement
(Y >= N * Z).
Possible Cause 1: The announcement interval may be too short or the
secondary announcement may be too long.
What to do: Check the number of callers waiting when the alarm goes off, as well
as the delay interval and the length of the secondary announcement.
If only a few callers are waiting when an alarm is signalled, increase the
announcement interval or shorten the secondary announcement to solve
the problem (see the second example in
If more than a few callers are waiting, go to Possible Cause 2.
Possible Cause 2: The primary announcement(s) require adjustment.
What to do: Depending upon your customer needs and current Group Calling
options, do one of the following to decrease the queue for the secondary
announcement:
If you are using several primary announcements, decrease the number of
primary announcements.
If the primary announcement is very short, increase its length so that
customers are not immediately sent to the secondary announcement
queue.
