CONTROL SYSTEM FOR MOVEMENT OF CODELESS TERMINAL

PURPOSE:To prevent the instantaneous disconnection due to switching at the time of moving between zones by providing the network with a multiconnection and OR adder connection functions. CONSTITUTION:A multi-connection control means 5, when a digital codeless terminal moves between zones, stores information for connecting both the old zone and the new zone in control memories 3 and 4 for a period of one frame, and carries out multiconnection. For example, this multiconnection stores new and old zone signals in two control memories 3 and 4, carries out OR addition, and sends the result to a connecting party. Even when a digital codeless terminal switches precedently, the terminal is connected corresponding to the new zone, and even when a time difference occurs when switching mutual connection between the codeless terminal and the switch, since multiconnection is done when switching was carries out, talking is not disconnected.
