The Development and Funture Assinment of Electronic Exchange

In this paper, we present, taking'into consideration the necessity of developing electronic exchange their backgrounds and present condition as well as the prospect of techniques absolutely requred in the information-oriented society. Also, the matheralizing plans for ISDN switching function and CEPT electrical transmisson and NO.7 signal mode-introduced-adaptablilty are analyzed and compared relatively. As a result of the research, the switching techniques required in a wide range of ISDN should not have any limitations in its mode and the speed of communication with characteristic highspeeding service than ever, and should have a fiexibilty and extensity to carry out the newlydevlopment ways of service without any difficulties, and also intergration of electrical transmission and switching system should be successfully carried out, by means of interface between users and communication networks. As a electronic switchboard is a kind of pivotal system, in especilly integrated-information networks as well as administration computerized network, with every effort we have to commercialize the prospective exchange ISDN & ATM, in the forth-coming years.
