ABSTRACT:
Casting of votes takes place by the dialing of a subscriber number of a stated destination switching center. By omitting establishing a connection to the destination switching center in the source switching center only the appropriate connection requests are summed and, after a predetermined sum value has been reached or after a given length of time has passed since the beginning of the vote taking, the particular sum value is signaled to the destination switching center via the common signal channel.
