■ If the number of waiting calls is less than the value programmed for
Threshold 1 or drops below that level, the LED is unlit.
■ If the number of waiting calls is greater than or equal to the Threshold 1
value but less than the Threshold 2 value, the LED flashes.
■ If the number of waiting calls is greater than or equal to the Threshold 2
value but less than the value for Threshold 3, the LED winks.
■ If the number of waiting calls is greater than or equal to the highest value,
Threshold 3, the LED lights steadily.
If all three thresholds are set to the same value, the result is one threshold only
with LED state either off or on (steady). If two values are the same, then the result
is two alarm levels (flash, steady). The factory setting is one call for all three
thresholds with LED states of off and steady.
In Release 5.0 and later systems, the primary delay announcements function like
the single announcement available in prior releases. After the delay
announcement (the primary delay announcement in Release 5.0 and later
systems), an inside caller hears a special ringback, a transferred inside caller
hears regular ringback, and an outside caller (including a transferred outside
caller) hears special ringback or Music On Hold, if programmed, until the call is
answered by a calling group member. The delay announcement or primary delay
announcement is played only once while the call is in queue.
In Release 5.0 and later systems, the system manager can specify the extension
for an optional secondary delay announcement and use system programming to
set the interval (0–900 seconds) between announcements. This setting
determines the time before a waiting caller hears the secondary announcement
or, if it is set to repeat, the interval between replays of the secondary
announcement. The secondary announcement can either repeat or play only
once, after which the caller hears ringback or Music On Hold, according to the
rules outlined above. The primary and secondary announcement options, when
used together, allow the system manager to issue an initial message to callers,
followed by a repeating announcement that, for example, urges the caller to stay
on the line and wait for a calling group member.
The external alert designated as a calls-in-queue alarm can be any alerting device
connected through an MFM in the External Alert mode for MLX telephones. That
alert is tied to the third threshold value. The alert stays on as long as the threshold
is exceeded. Only one external alert can be designated for each calling group.
Since the signal is continuous, you should only use lighted external alerting
devices. An alert connected to a Supplemental Alert Adapter for an analog
multiline telephone should not be used as a calls-in-queue alarm.
The Overflow Threshold determines the maximum number of calls (1–99) waiting
in the calling group queue before being sent to the Overflow receiver. The
Overflow Threshold Time determines the maximum amount of time that any call
waits in the queue before being sent to the Overflow receiver. The Overflow
Threshold should be set to a number larger than the third Calls-in-Queue Alarm
Threshold to ensure that the Calls-in-Queue Alarm will alert before calls are sent
