SYSTEME DE COMMUNICATION POUR CONNECTER DES POSTES D'USAGERS A DES LIGNES DE COMMUNICATION
摘要
A program controlled key telephone system which includes line modules and station modules for providing the interface circuitry between PBX/CO lines and stations is disclosed. System operations are controlled by a multi-phase clock which generates a reiterative list of binary coded signals based on a master program. The system is arranged for controlling the connection of calling lines to a first one of a group of stations after a prescribed interval upon detection of an off-hook condition at the station.
