Communication system with request-enable, request, and grant made over timeslotted multi-frequency channel
First Claim
1. A method of operating a data communication system comprising:
- transmitting a request-enabling signal from a communication controller to at least one node including a first node;
transmitting a request signal from the first node to the communication controller when the first node has a data to transmit, wherein said request signal is transmitted from the first node in response to receiving the request-enabling signal;
transmitting an authorization signal from the communication controller to the first node in response to the communication controller receiving the request signal from the first node; and
transmitting the data from first node to the communication controller in response to receiving the authorization signal from the communication controller, wherein the request-enabling signal, the request signal and the authorization signal are transmitted over at least one communication channel, said at least one communication channel comprising at least one frequency and at least one timeslot.

Abstract
A communication system is provided for communication between network nodes and a communication controller. In the network, a request-enable signal is transmitted from the communication controller to identify one or more timeslots or frequencies of a communication channel that a node may transmit. When a first individual node has data to transmit, the first individual node transmits a request signal to the communication controller over the same communication channel. In response to the request signal, the central control node transmits a grant signal over the communication channel. Finally, data is transmitted from the node as authorized by the communication controller.
