Abstract
A data switching device which implement the data exchange between a plurality of terminals connected to the communication network. Even if the circuit connection exists in the relevant input port and the destination port, since the frame is transmitted to the output part through the dual circuit switch path, the intermix mode service is processed in the output and then the effective intermix mode service can be processed. Also, since the same circuit switch is dually used, the high reliability regarding to the switch failure can be obtained.
