PURPOSE: A device for accommodating a V5.2 link by using an inner bus in a full electronic exchange is provided to combine an E1 link for a V5.2 interface by using the inner bus. CONSTITUTION: Link interfaces(501-50n) interface a link combined with a V5.2 subscriber unit. A V5.2 bus unit(40) supplies a communication path of I/O(Input/Output) messages of the link interfaces(501-50n). A V5.2 controller performs a serial of controls for a V5.2 subscriber. A V5.2 bus controller(30) designates a specific transmission link and a transmission channel for a message received from the V5.2 controller, and outputs the transmission link and the transmission channel to the V5.2 bus unit(40).
