Abstract: A digital payload for processing a sub-band spectrum received on an uplink beam at a communications satellite includes a digital channelizer, a digital switch matrix and a digital combiner. The digital channelizer divides the sub-band spectrum into a plurality of frequency slices that can be routed by the digital switch matrix to any of a number of receiving ports. A digital combiner receives the frequency slices and re-assembles them to form one or more output sub-bands for transmission on an output beam of the communications satellite. The digital payload may also include an embeddable digital regeneration module configured to demodulate some or all of the sub-band spectrum to extract a digital bitstream therefrom. The digital bitstream may be processed to implement code-based multiplexing, switching, access control, and other features.

Abstract: A data router for receiving input data, having a timing characteristic, and transmitting output data that is either bursted or non-bursted. The non-bursted data comprises frames of data with each frame comprising slots of data, each slot having a position and a number. The invention (200) provides translation between bursted and non-bursted formats and includes an input buffer circuit (104) for receiving input data from an input channel and storing the input data as the input data is received from the input channel. An output buffer circuit (210) is included for formatting the stored input data, translating between bursted and non-bursted data formats and outputting the formatted and translated data to an output channel. A sequencer (105) routing controller circuit controls the operation of the input buffer circuit (104) and output buffer circuit (210).

Abstract: An improved data router 10 with burst deshuffling and shuffling output buffers that performs input data deshuffling and output data formatting and shuffling using only one burst buffer per input channel 16 and one frame buffer per output channel 26. The router 10 includes input channels 16 for receiving input bursts, input burst buffers 14 for storing the input bursts, output frame buffers 23 for storing the input bursts in a deshuffled order and providing formatted and shuffled output bursts, output channels 26 for transmitting the output bursts and a router controller 20 for controlling the operation of the router. Due to the advantageous design of the data router 10 of the present invention, the input bursts and output bursts may be of different sizes and have different transmission data rates.
