OPERATING PROCEDURE
l. Depress the
Speaker
key; receive Dial Tone.
2. Dial a trunk access code and the desired number.
3. Receive Busy Tone or ring no answer. Depress the line key assigned as the
CALL BACK
key.
The associated LED flashes green and the LCD displays “
TIMED-Q
”. TIMED QUEUE is now set.
4. Within a preprogrammed time interval, the system will automatically seize a trunk (Dial Tone is
heard), redial the number (dialed digits are heard), and Ringback or Busy Tone (depending on the sta-
tus of the called party) will be heard at the station that set TIMED QUEUE.
5. Lift the handset and converse.
SERVICE CONDITIONS
l. The time between setting the TIMED QUEUE and when the system releases the trunk is programma-
ble from 4-120 seconds (30 seconds as set in default). During this period, the station’s
Speaker
LED
is lit and the station is considered off-hook by the system.
2. The time between the release of the trunk and the reseizure of the trunk is programmable from 4-120
seconds (60 seconds as set in default).
3. The number of times a TIMED QUEUE will occur is programmable from 1-7 times (3 times as set in
default). When the programmed number of attempts is reached, TIMED QUEUE will be canceled.
4. TIMED QUEUE is canceled if a station user either lifts the handset or depresses the
Speaker
key
while this feature is activated.
5. When a TIMED QUEUE occurs and Ringback Tone is supplied to the station, the station user should
immediately lift the handset when the called party answers. This operation cancels the TIMED
QUEUE; therefore, the period of Ringback Tone will not time out.
6. The combined maximum number of TIMED QUEUES set and OUTGOING TRUNK QUEUEING set
cannot exceed 32. When the maximum is reached and an attempt to access TIMED QUEUE is made,

s with an LCD will receive a visual and audible indication.
7. If all trunks are busy when reseizure is attempted, the system waits for a trunk in the same trunk route
to become idle.
