MERLIN LEGEND Communications System Release 5.0
Feature Reference 555-650-110
Features
Group Calling
Any multiline telephone in the system can be used to monitor the status of
a calling group's queue by programming a Calls-in-Queue Alarm button. An
MLX display telephone can be used to view the number of calls in a queue
(1–99) on the display when the user presses the Inspct button and then
presses the Auto Dial button (Calls-in-Queue Alarm button) programmed
with the calling group's extension number. The Inspect feature cannot be
used on a DSS button.
In Release 5.0 and later systems, three Calls-in-Queue Alarm thresholds can be
set to more clearly indicate the real-time status of the queue according to the
behavior of programmed Calls-in-Queue Alarm buttons. If all three thresholds are
set to the same value, the result is one threshold only with LED states of off and
on. If two values are the same, then the result is two alarm levels with LED states
of off, flash, and on. The factory is setting is one call for all three thresholds. Using
all three levels, the system manager sets Threshold 3 to the highest value,
Threshold 2 to a middle value, and Threshold 1 to the lowest value. A
Calls-in-Queue Alarm button indicates the severity of the alarm conditions in the
following ways:
If the number of waiting calls is fewer 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 fewer 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.
An external alert only signals when the number of calls in the queue is greater
than or equal to the programmed Threshold 3 value.
These thresholds can be used to assess the effectiveness of delay
announcements. See
Delay Announcements'' on page 293

Overflow Threshold

The overflow threshold is the maximum number of calls waiting in the calling
group queue before calls are sent to the overflow receiver. The factory setting is
one call.
The Overflow Threshold option should be set to a number larger than the
Calls-in-Queue Alarm Threshold so that the Calls-in-Queue Alarm alerts before
calls are sent to the overflow receiver. In Release 5.0 and later systems, the
overflow threshold should be greater than the highest Calls-in-Queue alarm
threshold (Threshold 3).
