Abstract:
A cross-connect switching device with Nf input lines and Nf output lines and N1 channels per line and being able to switch any of the Nf * N1 input channels to any one of the output lines, Nf * N1 being equal or greater than four (4), and the channels being equally distributed over the input lines, comprising:a switch being operatively connected to selected ones of the input lines of the cross-connects switching device and being adapted to switch at least one channel group on one input line of the switch en bloc to an output line of the switch, a channel group including a plurality of channels up to a maximum of N1 channels; a partial demultiplexer operatively connected to the switch for selecting at least one individual channel from at least one channel group, wherein the partial demultiplexer is adapted to generate a further channel group as well as the one selected individual channel, further comprising another switch located between the partial demultiplexer and a combiner unit and receiving the output of the partial demultiplexer and being adapted to switch the further channel group en bloc towards one of the output lines of the cross-connect switching device; and the combiner unit for combining the selected individual channel onto an output line of the cross-connect switching device.
