ABSTRACT:
The ATM switch includes a switch network section, a common section and an individual interface section. The ATM switch system can reduce a cost by sharing the common section in both cases of employing a simplex and a duplex individual interface sections. The common section includes a demultiplexer, a user cell discarding section, a header convertor, a multiplexer, an individual interface section information receiver, and a controller. The individual information receiver identifies whether the individual interface section has a simplex or a duplex structure according to information sent from the individual interface section. The controller sets the condition of demultiplexing the cells in the demultiplexer, and sets the condition of discarding the user cells in the user cell discarding section.
