Toggle Applications

This article describes different applications where the common scenario is to toggle a feature on/off using just a DAK key (or station input). Some features have options that gives additional opportunities.

The Station Input or Station DAK key event is the preferred event for most of the applications.

Conversation

As from AlphaCom v. 13 a call can be toggled on/off from a DAK key by setting the flag Idle DAK during conv. cancel ongoing call. No need to program any events

Toggle between Call and Cancel: pressing DAK key 1 sets up a call to station 101. Second press cancels the call. A second event must be created to handle the scenario where 101 initiates the call , or ends the call.

First DAK key press: Call.
Second press: Cancel

Action commands:

IF %udd(%1.phy)
$C L%1.dir
WUDD %1.phy 0
STOP
ENDIF
$CALL L%1.dir L101
WUDD %1.phy 1

Adjust UDD if call initiated or ended from the other station

Action commands:

WUDD %1.phy %chg(1,0)

The same DAK can also answer an incoming call in private mode. Then the following event must be added:

Adjust UDD if call initiated or ended from the other station

Add some commands to the top of the initial DAK as RCI event, making it look like this: Action commands:

IF %op(%udd(%1.phy),=,2)
$M L%1.dir
pause
$MREL L%1.dir
WUDD %1.phy 1
STOP
ENDIF
IF %udd(%1.phy)
$C L%1.dir
WUDD %1.phy 0
STOP
ENDIF
$CALL L%1.dir L101
WUDD %1.phy 1

For more details see $CALL, $C, $M, $MREL and pause

Call Request

Toggle between Call Request and Cancel Call Request: Pressing the DAK key the first time sends a Call Request to station 101 in the example. Second press cancels the call request. A second event must be created to handle the scenario where 101 answers the call request, or cancels it.

First press: Make a Call Request to 101
Second press: Cancel the Call Request

Action commands:

IF %udd(%1.phy)
$CANM L%1.dir L101
WUDD %1.phy 0
STOP
ENDIF
$SM L%1.dir L101
WUDD %1.phy 1

Reset UDD when station is no longer in Call Request mode (i.e. the Call Request is for any reason removed)

Action commands:

WUDD %2.phy 0

To add the possibility to answer incoming calls in private using the same DAK, see the Conversation application example.

For more details see $CANM, $SM and Call Request

Audio Program

Toggle between Program ON and Program OFF. The example shows program 1 (801).

First press: make the station listen to program 1 (801)
Second press: Turn listening to program off

Action commands:

IF %udd(%1.phy)
$PROG L%1.dir LV
WUDD %1.phy 0
STOP
ENDIF
$PROG L%1.dir L801
WUDD %1.phy 1

Stepping through several programs can be performed by using the step codes 790 and 791 configured in the DAK settings:

790: Step to next program
791: Step to previous program

An event can also be created to do this. The example below uses DAK 4 for stepping to next program, and DAK 5 for stepping to previous program.

DAK4 (or input 4) activated: Step to next program
DAK5 (or input 5) activated: Step to previous program

Action commands:

IF %op(%sev,=,4)
$DD L%1.dir L790
ENDIF
IF %op(%sev,=,5)
$DD L%1.dir L791
ENDIF

For more details see $PROG and Audio Program

Transfer

Toggle between Transfer ON and Transfer OFF. The example shows transferring calls to directory number 101.

First press: Activate call transfer to 101
Second press: Deactivate transfer

Action commands:

IF %udd(%1.phy)
$TRF L%1.dir ""
WUDD %1.phy 0
STOP
ENDIF
$TRF L%1.dir L101
WUDD %1.phy 1

Toggle between Call Request Transfer ON and Call Request transfer OFF. The example shows transferring Call Requests to directory number 101.

First press: Activate Call Request transfer to 101
Second press: Deactivate Call Request transfer

Action commands:

IF %udd(%1.phy)
$SCRT L%1.dir
WUDD %1.phy 0
STOP
ENDIF
$SCRT L%1.dir L101
WUDD %1.phy 1

Option: If using a station with LED indications on the DAK keys (i.e. CRM-V or ECPIR-3P) the LED can be switched on and off to show status of the transfer. Change the action commands for the transfer event like this: (example shows red LED) Action commands:

IF %udd(%1.phy)
$TRF L%1.dir ""
WUDD %1.phy 0
IND %1.phy %1.dir(i%2.dir) 1 1 OFF
STOP
ENDIF
$TRF L%1.dir L101
WUDD %1.phy 1
IND %1.phy %1.dir(i%2.dir) 1 1 ON

For more details see $TRF, $SCRT and IND

Simplex Conference

Toggle between joining a simplex conference (SX), and leaving it. The example shows joining/leaving SX1 (8201).

First press: Join Simplex Conference 1 (8201)
Second press: Leave the Simplex Conference

Action commands:

IF %udd(%1.phy)
$CONF L%1.dir LV
WUDD %1.phy 0

Volume adjustment

Stepping the volume in a circle using just one button. After max volume, the next step is minimum volume.

Activating the DAK (or an input) increments the volume by 1

Action commands:

IF %op(%vol(%1.phy),=,9)
$VOL L%1.dir U0
STOP
ENDIF
$VOL L%1.dir U%op(%vol(%1.phy),+,1)

Alternatively the volume stepping can be in double rate, incrementing the volume by two for each button press:

Action commands:

IF %op(%vol(%1.phy),=,9)
$VOL L%1.dir U1
STOP
ENDIF
$VOL L%1.dir U%op(%vol(%1.phy),+,2)

Using a station with two buttons (or two inputs) assigning one for volume up, and one for volume down:

Adjusting volume up when pressing DAK4 (input4)

Action commands:

IF %op(%vol(%1.phy),=,9)
STOP
ENDIF
$VOL L%1.dir U%op(%vol(%1.phy),+,1)

Adjusting volume down when pressing DAK5 (input5)

Action commands:

IF %op(%vol(%1.phy),=,0)
STOP
ENDIF
$VOL L%1.dir U%op(%vol(%1.phy),-,1)
