NOTE:
Message-waiting indications cannot be sent to the extension number
assigned to the group unless this option is programmed. The message-
waiting receiver cannot distinguish between messages left for the Calling
Group and personal messages.
Overflow Threshold (Calls-in-Queue Alarm Threshold)
The Overflow Threshold is the number of calls (1-99) allowed in the queue
before calling members are notified. When the number of waiting calls is equal
to or greater than the programmed Overflow Threshold (factory setting is one
call), the Calling Group members can be notified in one of two ways:
■ Via an assigned external alert connected to an analog multiline
telephone by using a supplemental alert adapter (SAA), or connected to
an MLX telephone by using an MFM. Since the tone sent to the alert is
continuous, it is recommended that only a device such as a strobe light
be used, which stays lit until the number of calls drops below the limit.
Only one external alert can be assigned to each Calling Group, and
each external alert can be assigned to only one Calling Group.
The system does not block the programming of any station jack
(including station jacks used for telephones or system operator consoles)
as an external alert that provides Calls-in-Queue Alarm indication.
However, programming a telephone as a Calls-in-Queue Alarm is not
recommended because the telephone rings continuously while the
number of calls in the Calling Group queue is equal to or greater than the
programmed threshold.
■ Via the LED associated with a Calls-In-Queue button programmed with
the Calling Group’s extension or a DSS button that corresponds to the
extension. The LED associated with either type of button does not go out
until the number of calls drops below the programmed limit. There is no
limit to the number of buttons that can be programmed to provide the
Calls-in-Queue Alarm indication.
Any multiline telephone in the system can be used to monitor the status
of a Calling Group’s queue by programming the 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 by pressing the Inspect button
and then pressing the Auto Dial button programmed with the Calling
Group’s extension number. The Inspect feature cannot be used on a
DSS button.
Overflow Receiver
When the number of calls waiting in the Calling Group queue reaches the
Overflow Threshold, calls can be sent to an Overflow Receiver, which can be
another Calling Group or the Queued Call Console (QCC) queue. Only one
Calling Group or the QCC queue can be programmed to provide overflow
coverage for the same Calling Group, and each Calling Group or the QCC
