Abstract:
A method of operating a data communication system, the data communication system including a communication controller and a plurality of nodes, the method comprising:transmitting a first signal from the communication controller to a first node, said first signal specifying a timeslot in which the first node may transmit a capacity request signal to the communication controller;when the first node has data to transmit, and upon receipt of the first signal, transmitting a capacity request signal from the first node to the communication controller, said capacity request signal including a request for an allocation of bandwidth capacity to transmit data from the first node to the communication controller;in response to the capacity request signal, transmitting a data grant signal from the communication controller to the node, said data grant signal specifying at least one timeslot for the first node to transmit data to the communication controller; andin response to receiving the data grant signal, transmitting data from the first node to the communication controller.
