Switch and switching method for processing communication data of a particular connection

摘要

Data from an STM (Synchronous Transfer Mode) network is converted into an ATM (Asynchronous Transfer Mode) cell by an interworking facility, and the ATM cell is input to the ATM network. If the input cell corresponds to a connection which requires voice processing, a voice processing trunk within a switch performs the processes such as an echo compensation process, an encoding process, a multiplexing process, etc. The switch outputs the cell to a trunk line of the ATM network.
