ABSTRACT:
Method for the establishment in a communication system of a connection between a communication terminal apparatus and a plurality of further apparatus. To accelerate the switching-on of the respective apparatus of the plurality of further apparatus (separate loudspeaker, loudspeaker of the terminal apparatus) for the purpose of a group announcement, on the basis of a group-individual identification number (KZ), a switch-on request is generated by a computer control (ASt) and is simultaneously transmitted to a limited number (maximum number) of apparatus of the plurality of further apparatus by the computer control (ASt). A counter (PZ), set for this number, is decremented for each receipt information item (ZRS) received by the computer control from the limited number of apparatus. Further switch-on requests (VA) are then transmitted to the apparatus of the plurality of further apparatus until the maximum predetermined number is again reached. With the receipt signal of the last group (KE-D-Bg) of the group (GR) the operator at the communication terminal is informed by a corresponding tone (TSg) that the effective switching-on of all the free apparatus of the group has taken place.
