Abstract
The object of this invention is to provide a multiplex transmission system which can effectively reduce the traffic amount associated with digital information on a communication line and can improve the efficiency of digital information transmission during a period after the beginning of activation of each of a plurality of communication nodes connected to the communication line until the communication nodes are set in a normal operation state. The multiplex transmission system includes a communication line (11) for transmitting multiplexed digital information, and a plurality of communication nodes (12A, 12B, 12C) each of which incorporates an arithmetic processing unit, and performs an information output operation for outputting digital information onto the communication line (11), and an information fetching operation for selectively fetching digital information from the communication line (11). Upon activation of the plurality of communication nodes (12A, 12B, 12C), a communication node, which is set in a normal operation state earliest, of the plurality of communication nodes (12A, 12B, 12C) outputs digital activation information, and the remaining nodes are shifted to the normal operation state in accordance with the digital activation information.
