  • Power-saving full duplex nodal communications systems
    Patent number: 5359594
    Abstract: An inter-nodal communication system employs full duplex transmission links to connect asynchronously operating nodes. Links between nodes are quiesced to a no-current flow state in the absence of message traffic. The system employs a communication protocol that incorporates time-outs which (1) enable a broken link to be detected at the inception of a message and (2) prevent a receiver from listening to a link which has been quiesced by a transmitter at the other end of a link that is shutting-off. All synchronization messages in the inter-nodal communication network are carried by data links and no additional communication wires are required.
