Secondary Announcements Not Playing as Programmed						Page 8-28

		Table 8–1. Checking the Effectiveness of Delay Announcements

		Calls Waiting for	Length of
		Secondary	Secondary	Announcement
		Announcement	Announcement in	Interval in
		(N)	Seconds (Z)	Seconds (Y)	N * Z	Is N * Z > Y?
		3	10	30	30	No
		3	20	30	60	Yes
		5	15	90	75	No
10			15	90	150	Yes

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. Table 8–1 illustrates situations where a programmed Calls-in-Queue 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 Table 8–1).

■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.
