2-2e. Event Trigger - Event Handler (solution)

System configuration

Solution

Call setup:

• The Entrance and the SOS Point should be configured to make a Call Request (623 + 101) to the Control Room.

Select the Entrance station in the list box, press DAK button, and enter "I 623 I 101" on DAK 1. Do the same for the SOS Point station.

• The Control Room should be configured as a CRM (Control Room Master), the DAK display should be enabled, and the Navigation Keys should be used for call queue navigations.

Select the Control Room station in the list box, and set "Station Type" = CRM.

Select the Control Room station in the list box, select the "Station Type" tab, and enable the "Station use DAK Display" flag.

Select the Control Room station in the list box, press DAK button, select the "Navig.keys" tab, and enter 7638 (Answer), 7639 (Next), 7632 (Top) and 7630 (Cancel)

Toggle Call Request Forwarding:

• When dialing the event trigger number 9533, or when pressing a DAK key programmed to 9533 on the Control Room station, the following features should be toggled ON/OFF every time the number is activated:
  • Turn on/off Call Request Forwarding from Control Room station 101 to station 103 (M. Larsen), so that all new call requests will be forwarded to station 103. Use the command "$SCRT" for this.
  • Turn on/off a lamp (use RCO 3) to signal that call forwarding is active
  • Write to the System LOG that the call forwarding has been activated/turned off. Use the LOG "..." statement.

Select the Control Room station in the list box, press Events button, and Insert a new event with parameters shown on the screenshot.

The full action string is:

IF %udd(1)                                           If Call Forwarding is active (UDD 1 different from 0")
$SCRT L101                                           Turn off Call Forwarding at 101
RCO 3 OFF                                            Turn off RCO 3
LOG "Control Room: Call Forwarding turned off"       Send info to System log 
WUDD 1 0                                             Set new status = Call Forwarding not active (UDD 1 = 0)
STOP                                                 Don't execute the rest of the actions
ENDIF                                                If Call Forwarding is not active (UDD 1 = 0)
$SCRT L101 L103                                      Turn on Call Forwarding at 101
RCO 3 ON                                             Turn on RCO 3
LOG "Control Room: Call Forwarding active"           Send info to System log
WUDD 1 1                                             Set new status = Call Forwarding active (UDD 1 = 1)

Program DAK 1 of the Control Room station with the code for Call Forwarding on/off (9533), and add an appropriate display text.

Select the Control Room station in the list box, press DAK button, select the "DAK 1-10" tab, and on DAK key 1 and 2 enter 9533 T <text>.

Verify that:

• Call Forwarding is toggled on and off
• RCO 3 is toggled on and off
• The Call forwarding on/off is logged in the "System Log" (AlphaWeb: System Monitoring -> Logging. It might be that logging has to be enabled first: System Configuration -> Logging).
