  • Patent number: 3967072
    Abstract: An electronic key telephone system is disclosed in which connections among the station sets and telephone lines are made in a central time division switching network remote from the station sets. Each station set and line is equipped with a port circuit having an individual shift register for defining the time slot interval during which a connection may take place. To assign a time slot to a port circuit, the main controller interrogates the network to find an idle time slot and then furnishes that time slot number to the network controller. In order to save central memory and to increase system reliability, the main activity memory which stores an indication of which ports are or should be interconnected in the network need not contain any reference to the time slot number assigned for the particular connection. In order periodically to verify that actual network connections reflect the state of the activity memory, two types of audits are performed.
