Abstract
The present invention relates to an Asynchronous Transfer Mode (ATM) multi-channel switch with a structure of grouping/trap/routing that, by designating a port as a group, could accept not only the services having higher speed than the speed of input ports, but also the services having super-rate speed by comprising: an input processing unit for executing reading control of externally inputted cells and adjusting synchronization between an externally inputted cell and a cell returned by blocking and feedback; a channel grouping unit for grouping cells outputted from the input processing unit, according to switching control data; a trapping unit for deciding whether cells grouped in the channel grouping means require switching beyond the capacity of the pertinent channel and, if these cells require switching beyond the capacity of the channel, sending them to the input processing unit by feedback; and a routing unit for routing cells outputted from the trapping unit.
