An apparatus and method for a non regenerative multibeam communications system with FDMA access and SSTDM connectivity. In accordance with the present invention, FDM input signals are transformed into corresponding TDM input signals. The TDM input signals are matrix switched and routed along the desired output transmission path(s). The TDM input signals routed along each output transmission path are then transformed into corresponding FDM output signals prior to further processing or transmission. The apparatus and method make it possible to provide full interconnectivity using time domain processing in a FDMA/FDM system.
