Patent ID: 6847619

Claim:
A dual protocol mode of operation multiple access system for spread spectrum data link communication between a central hub station and a plurality of spoke stations, comprising: means in said spoke stations for generating priority request interrupts during a spoke epoch time having a plurality of time division slots, said spoke epoch time comprising one or more dedicated spoke time slots in which each spoke stations can transmit data or requests with priorities to said central hub station to the exclusion of all other spoke stations, said spoke epoch time further comprising one or more spoke priority interrupt request time slots in which all spoke stations can simultaneously transmit spread spectrum priority interrupt requests to said central hub station without collisions, controller means in said central hub station for evaluating said plurality of spoke station interrupt requests, means in said central hub station for granting transmission access to one of said spoke stations requests during predetermined time slots in the next spoke epoch time to the exclusion of all other spoke stations, and said means for granting transmission access including means for resynchronizing timing in said spoke station.
