ABSTRACT:
In a multi-data transmission system utilizing two or more parallel data-transmission lines in LAN, erroneous data distribution occurring in the data-transmission lines is detectable. A data transmission apparatus includes: a plurality of data-transmission lines arranged in parallel with each other, and a plurality of transmission stations coupled via the plurality of data-transmission lines to each other. Each of the transmission stations includes adders for adding to send data, transmission-line information representative of a specific data-transmission line so as to obtain send data with the specific line information; and, receiver/detector for receiving the send data with the specific line information which has been transmitted from one transmission station, in order to judge whether or not the received send data contains the correct specific line information. Accordingly, erroneous data distribution occurring in the data-transmission lines can be detected.
