DC CAFCFirst Claim
1. A method of operating a two-way communication system between a plurality of communication devices which comprise at least one communication controller including a first communication controller and a plurality of nodes including a first node, the method comprising:
- receiving a clocking signal used to enable request signals including a first request signal from the first node, the clocking signal provided from the first communication controller;
when the first node has a communication message to transmit, and upon receipt of the clocking signal, transmitting the first request signal from the first node to the first communication controller; and
receiving an authorization signal at the first node from the first communication controller;
upon receipt of the authorization signal, transmitting the communication message from the first node subsequent to receiving said authorization signal to the first communication controller;
wherein each of the first request signal, the authorization signal, the communication message, and the clocking signal are transmitted on differing frequencies, andwherein the clocking signal further enables a second request signal to be transmitted to the first communication controller by a second node, and wherein the second request signal can be provided simultaneous with transmission of the communication message.

Abstract
A communication system is provided for communication between network nodes and a communication controller. In the network, a request signal is transmitted from a first node to the communication controller when the first node has a packet data message to transmit. The communication controller then acknowledges the request, and the first node transmits its data message in response. The communication controller further transmits a clocking signal allowing synchronization of the node signals with the controller signals. The clocking signal, request, acknowledgement and data message can all be provided on different frequencies, allowing simultaneous transmission of these signals for efficient operation.
