A controller is provided for a baseband switching matrix with one space switching stage. The matrix supplies the controller with a number of service channels (IOTS, CH) of the uplink frames, which channels comprise encoded commands that are decoded by the controller which generates service channels (IOTD, FMC) for the downlink frames and sends them towards the matrix. The controller is subdivided into three functional units: a preprocessing unit (PREL) which decodes uplink frame service channels; a processing unit (ELAB), which receives the commands decoded by the preprocessing unit and/or by a telecontrol station with which it performs a bidirectional dialogue and generates control signals comprising the matrix switching states; and an interface unit (INTM) comprising two memories (MEMA, MEMB) alternatively operating as active or backup memory, which store the switching states supplied by the processing unit and send them to the matrix.
