The invention relates to a switching system, in particular for communication satellites, for switching m digital data signals at m data inputs to n data outputs, and is characterized by the fact that the m data signals arriving at the m data inputs are combined on a single central TDM bus by time-division multiplexing, that an output module and a buffer are allocated to each data output and that the output modules in each case take the data intended for the relevant output from the TDM bus and load them into the associated buffer (Figure 1). <IMAGE>
