A high reliability information transmission system which can continue transmission upon at the occurrence of multiple failures. The system includes two transmission lines and transmission terminals coupled to both of the transmission lines. Data can be transmitted between respective terminals using both transmission lines. The transmission terminals check the data reception status at the corresponding receiving terminals. When data is not being received, the data may be relayed to the receiving terminal using one of the other transmission lines.
