Group Call - Increased volume

This article describes how to increase the volume of the gong signal, and set it back to normal when the group call is answered (or canceled).

As from firmware version AMC 10.23 the volume to a station can be changed by the data command VOL. By using 4 events the Event Handler, one can set a higher volume during the gong signal, and set it back to a normal level when the call is answered.

In the following example a door station (101) is making a group call with repeatative gong to group 4. The members in group 4 also needs to be members of UDP group 7. In AlphaPro, go to Exchange and System -> Events, press Insert and create the following events:

Event Owner:	Station Id: Id: 1 (101 The Door)
Event type:	15 - Event Trigger Feature
Sub event:	0
When change to:	ON
When related to:	Id: 9534
Action:	WUDD 2 0
	$ER U15 U1 U1 U1 L101 U3 L9001

In the first event an UDD is set, and an Event Report is started.

Event Owner:

Station Id: Id: 1 (101 The Door)

Event type:

15 - Event Trigger Feature

Sub event:

1

When change to:

ON

When related to:

Id: 9001

Action:

WUDD 1 %gns(4,%udd(2))

IF %udd(1)

$VOL N%udd(1) U6

WUDD 2 %udd(1)

$ER U15 U1 U1 U1 L101 U3 L9001

STOP

ENDIF

$DD L%1.dir L87

WUDD 1 0

WUDD 2 0

In the second event the mebers from group 4 is registered, and the volume on these members are set to level 6. An Event Report loops the event intil all group members are registered. Finally The Door station (101) is forced to dial 87 which is the directory number for group 4.

Event Owner:	Station Id: Id: 1 (101 The Door)
Event type:	08 - Conversation Outgoing
When change to:	ON
When related to:	Id: 7
Action:	WUDD 2 0
	$ER U15 U2 U1 U1 L101 U3 L9002

In the third event an UDD is set, and an Event Report is started.
