PURPOSE:To simplify the processing of a main body processor without the influence to a remote station and to enhance the processing capacity by processing the link control of a No.6 signal and the transmission and receiving processing of the No.6 signal by a processor different from the main body processor. CONSTITUTION:A service line (a) of a No.6 signal system is controlled by the main body processor CPU, the No.6 signal links C1, C2 are connected to a No.6 control processor N6CPU, and the No.6 signal link control and the No.6 signal transmission and receiving processing are carried out by the No.6 control processor N6CPU. Then, a signal received in the No.6 control processor N6CPU is converted into a logical signal and fed to the main body processor CPU by the communication between the processors. In the main body processor CPU, the No.6 signal system can be processed unconsciously, so that a calling control (channel control) similar to other signal system is obtained and the processing is simplified. Since there is no No.6 signal link control and the no.6 signal transmission and receiving processing from the main body processor CPU, especially, there is no signal relaying function of a signal trunk point (STP) signal, the high traffic processing of a telephone is carried out without the influence by the safety policy of the signal link of the No.6 signal system.
