PURPOSE:To reduce the load of a central processor unit (CPU) sharply at the sending of originating terminal information by forming a terminal information separating circuit, previously reading out subscriber's terminal information from a main storage and storing the information in a reading terminal information storing circuit. CONSTITUTION:The terminal information memory circuit 108 for storing the subscriber's terminal information and a terminal information sending circuit for reading out the subscriber's terminal information of an originating terminal in the memory circuit 108 and multiplying the read information by a calling signal or a data signal in the succeeding multiplying circuit 111 are formed in a channel switch part 100 of a channel network controlled by the CPU 105. On the other hand, the terminal information separating circuit for separating and receiving the subscriber's terminal information from the received calling signal are formed in respective subscriber circuits 103, 104. Since the subscriber's terminal information can be transferred to the subscriber circuits through the channels simultaneously and similarly with the connection of the call, the CPU can execute both the connection of the call and the transfer of the subscriber's terminal information only by sending a call connection instruction, reducing the load of the CPU sharply. |
