ABSTRACT OF THE DISCLOSURE Reconfigurable switching router connects to an existing connectivity network on board a multibeam communications satellite for increasing the flexibility thereof by providing variable bandwidth capability 80 that the satellite handles a multitude of individual users having different requirements of bandwidth and transmission rates. The bandwidth of at least one transponder channel is split into two portions. A first portion provides a VBVCF continuous passband while a second portion is further channelized in a reconfigurable fashion to achieve VBVCF subchannelization. The reconfigurable switching router utilizes a class of multi-level channelization formats implemented by a plurality of filter banks connected in parallel. A switching network performs VBVCF subchannel selection and routing via time and/or frequency multiplexing thereby to accommodate both VBVCF SSTDMA and SSFDMA traffic.
