Abstract
A method uses a synchronous bus which ensures the transfer of digital data between plural subscribers connected to the bus via respective couplers. This method comprises the attribution to the subscribers of transmission rights in cells of fixed duration distributed over the frames, the synchronizing of all the couplers, the composing by each coupler of a message comprising the data to be transmitted associated with a code identifying the message, the transmission of this message during a cell attributed to the subscriber, the reception by each coupler of the messages contained in the cells not attributed to it and the analysis of the identification codes of these messages, and if this identification code corresponds to that of the message expected, the transmission of the data in the message to the subscriber.
