ABSTRACT:
An apparatus for switching data between a first set of bitstreams and a second set of bitstreams, each of said bitstreams being divided into recurring frames and each of said recurring frames being divided into time slots, is disclosed. The switch comprises a first set of switching elements, at least one intermediate set of switching elements, and a last set of switching elements. Each switching element comprises a number of input ports and a number of output ports. The input ports of the first set of switching elements are arranged to receive the first set of bitstreams and the output ports of the last set of switching elements are arranged to provide said second set of bitstreams. Furthermore the switching elements are arranged so that there are more than one path from a switching element in the first stage to a switching element in the last stage. Each switching element is arranged so that it provides for both time and space switching of data from incoming bitstreams, referring to the input ports of the switching element, to outgoing bitstreams, referring to the output ports of the switching element.
