ABSTRACT:
A data transmission apparatus has a data transceiver which transmits data for one among a number of stations, to all of a number of output terminals, and which receives at one of its input terminals data sent by any one of the other stations, fetches the data into its own apparatus, and at the same time, transfers the receiving data to output terminals for all stations except the station which has sent the data, thereby enabling communication via a plurality of different paths and not making communication impossible even if disconnection is present in a transmission path.
