1. A method of configuring a satellite payload for use in a multi-spot-beam communication system comprising the steps of:

  • providing a plurality of spot-beam uplinks each of which receive signals transmitted from a particular section of a total geographic area to be serviced by the communication system;

    providing a plurality of spot-beam downlinks each of which transmits signals to a particular section of the total service area;

    providing a broadcast downlink which transmits a single wide-area beam to the total service area;

    routing point-to-point transmissions received by said plurality of uplinks to a particular one of said plurality of downlinks;

    routing broadcast transmissions received by said plurality of uplinks to said broadcast transmission link in a non-blocking manner; and

    providing a surge mechanism by routing to the broadcast downlink point-to-point transmissions of any of said plurality of spot-beam uplinks and spot-beam downlinks whose transmission capacity is exhausted.
