Dynamic group call

Operation (CRM IV)

• Press the "Group Config." button, red led in key starts flashing
• Select subscribers to be included / excluded (toggle function), flashing green led in key indicate included
• Press the "Group Config." button again, the group call is activated, red led in key stops flashing
• The green leds continue to flash during the group call
• When the group call is cancelled the group is emptied, and the green leds stop flashing

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 CRMIV must “own” a group call that nobody else uses. The directory number of the group call should 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 associated to the CRMIV in the External Parameter (%1.EXP) field of the CRM IV.
• Put all CRM IV’s that should have Dynamic Group Call feature in UDP group 1.
