<p>A signal switching assembly comprises a pipeline sort matrix having a plurality (N) of input and output ports. A number of signal switching units are arranged in series between the input and output ports, the input ports being coupled with an upstream signal switching unit (7) and the output ports being coupled with a downstream signal switching unit. The switching units are coupled together so as to be able to perform a perfect shuffle algorithm or a group of output port addresses supplied to the input ports during a reset operation. The pipeline sort matrix is controlled by a control system (33,34,35,36) which generates selection signals which are supplied to each signal switching unit to reset the status of the signal switching unit so that after the status of each signal switching unit has been reset, selected input and output ports are coupled together. The control system is adapted to reset each signal switching unit in turn.</p> |
