An electronic register sender that uses electronic/ electromechanical interfaces to receive dialed information via special relay sets positioned between the linefinders and first selectors of a step-by-step telephone system is described. These interfaces are connected in turn via time-divided highways to a common control circuit. The common control has a recirculating memory that stores the information for all interfaces and has access to a translator. It provides for classes of service, extended area service (EAS) and direct distance dialing (DDD) calls, and can be added to existing systems.
