Abstract
A calling subscriber, in dialing a special code before a subscriber number, causes a renunciation character to be stored in a trunk exchange to provide him with priority in trunk line selection, when reduced charge metering equipment, is in operation; otherwise, priority is equal for all calls. Upon completion of trunk connection on a priority basis, a charge reduction signal is transmitted to the charge metering equipment. If all trunks are busy, a priority call is provided with a predetermined number of repeated trunk selection cycles.
