PURPOSE:To perform economically various services and functions of a digital line and services such as reservation registering, fixed time communication setting of an analog line by storing not only the analog line but also the digital line in a space division switch and making the switching processing between time slots having the same phase possible. CONSTITUTION:A space division switch 100, a switch driving means 110 which drives directly the switch 100, a central processing unit 120 which sets the order of the switch 100 and is controlled by a program, a central path 130 through which the central processing unit 120 sets the order and transmits and receives information, order setting parts 131, 132, and 133 related to the switch 100, a switch control memory 140 where control information including intersection switching information of the switch 100 are stored, and a switch control means 150 which is provided between the central processing unit 120 and the switch driving means 110 and controls the switch 100 through the switch driving means 110 are provided. Thus the program control of reservation registering, fixed time communication setting, etc. is possible.
