Dynamic group call

Operation (CRM IV)

• Press a dedicated "Group Config." DAK key. The red led in key starts flashing
• Select subscribers to be included/excluded (toggle function) by pressing the assosiated DAK keys. A flashing green led in key indicate that the station is included
• Press the "Group Config." button again, the group call is now activated. The red led in the DAK key stops flashing
• The green leds continue to flash during the group call
• Cancel the group call. All members will be removed, and the green leds stop flashing

It is not neccessary to use CRM-IV stations, but with regular stations you will not get LED feedback on groupcall incusion/exclusion.

LIMITATION: You can only include subscribers, you cannot include groups!

Programming

• Software requirement: AMC 8.26 or later
• If not already existing, create 9535 = feature 95/0. The "Group Config." DAK button is programmed to 9535.

• Each CRM-IV must “own” a group call that nobody else uses. The directory number of the group call must be changed so that the two last digits are identical to the group index number. Example:
  • Group 2 = 8502
  • Group 10 = 8510

• Enter the group call directory number in the User Defined Parameter (%1.EXP) field of the CRM IV (AlphaPro: Users & Stations > UDP > User Defined Parameter (%1.EXP)).
• Put all CRM IV’s that should have Dynamic Group Call feature in UDP group 1.
