Abstract: Control lines for routing in which senders and receivers are linked to each other by real-time lines and real-time signals observable on these lines are sent out in series in a frame, on one and the same series link. Starting and ending signals of a particular shape are send with the real-time signals on the link so as to facilitate especially a detection of errors, a synchronization between senders and receivers and an evolution of the system in terms of number of real-time lines, without modifying its cabling.

Abstract: A method, a network and an apparatus having the network in which a star network is formed by CAN type buses using a repeater where each arm can be isolated from the other arms. CAN buses are connected to one another by means of the repeater that duplicates the signals observable on one bus on all the other buses connected to it. Communications circuits and/or controllers are connected to the repeater Depending on the reception signal received, the repeater organizes operations of sending transmission signals to the communications circuits and the controllers.
