Abstract
PURPOSE:To join a LAN without being conscious of a transmitting fundamental part with respective terminals by making preparations for an interface to meet the communication mode and communication procedure of respective terminals for one loop-shaped LAN. CONSTITUTION:For a transmitting fundamental part 24, the interfaces such as a fixed communication type interface part 21, a token ring type interface part 22 and a packet line exchange type interface part 23. Thus, the signal from the terminal such as a data terminal 100 for fixed communication, a terminal 200 for exchanging a message, a telephone terminal 300, a facsimile terminal 400 and a host computer 500 is inputted to respective LAN interface parts, after the signal is gatewayed here, the signal is multiplexed by a multiplexing transmitting fundamental part 24 and transmitted to other terminal station device by an optical fiber cable 10.
