Abstract
A method of transmitting information in the form of electrical signals over a bidirectional link including a central station (S. C.) and a peripheral station (S. P.) connected to the central station via a bidirectional transmission bus (10), where the central station (S. C.) is provided with a clock (14) furnishing a synchronizing signal to the peripheral station (S. P.) is proposed, the method being characterized in that the synchronization is effected in the biphase mode upon transmission from the central station (S. C.), and in the monophase mode upon transmission from the peripheral station (S. P.). The invention is applicable to data transmission over a bidirectional link between various subsystems of a data processing system. The invention also relates to an apparatus for performing the above method.
