NOTE: If the number of digits in the paging zone is set to 0 (see Table 2-1),skip step 2 and proceed to step 3.

Important: If all the recording time is used up, the Call Stacker responds with two consecutive low tones then disconnects. If this occurs your announcement has not been recorded. Wait a few seconds before re- attempting to record the announcement.

1.Dial up the input station connected to the Call Stacker and wait for the Call Stacker to answer the trunk and respond with a high tone. Proceed to step 2.

2.Enter a DTMF tone sequence using the telephone keypad to select a paging zone. Once the required number of DTMF digits (see table 2-1)are entered, the Call Stacker responds with a high tone. Proceed to step 3.

3.Record the announcement. To end recording, either:

■Hang up to enter the recorded announcement into the queue, or

■Press the “#” k ey to hear the recorded announcement. The Call Stacker responds with a high tone, plays back the recorded announcement and then responds with a second high tone. Press the “0” key to re-record the announcement and return to step 2 or hang up to accept the announcement and enter it into the queue.

NOTE: If more than one announcement is in the queue, the control contact remains open for a minimum of 250 msec.

Once a recorded announcement is entered into the queue, the Call Stacker immediately closes the control contact on the Page Output channel to access the paging system controller.

The Call Stacker then plays out the recorded DTMF sequence to select the paging zone followed by the recorded announcement.

At the end of the announcement the Call Stacker erases the announcement and opens the control contact on the Page Output channel to release the paging system controller.

Important: If at any time a contact closure is detected on the Pause Override Control Input, the Call Stacker immediately terminates the outgoing announcement and requeues it for playback in its entirety once the contact closure is removed.
