<p>The present invention provides a cross-connect switching device (100) and a method of cross-connect switching of Nf * N1 channels to one of a plurality of output lines (201, 202) of the switching device, Nf * N1 being equal or greater than four. The device and method includes three basic elements: 1) a partial demultiplexer (20, 21) )for partially demultiplexing the channels on its input lines (111, 112) into groups of channels and individual channels; 2) a space switch (18) for switching groups of channels en bloc; and 3) a combiner unit (22) for combining individual channels onto one of the output lines (201 202) of the cross-connect switching device (100). The cross-connect switching device according to the present invention may be combined with similar or dissimilar switching devices to form a larger switching device. <IMAGE></p> |
