The transmitting circuits DRV and receiving circuits RCV of E1 to TEn were connected in common, and a plurality of information channels 11 to 1m were arranged in a time division format on the transmission line BUS as shown in FIG. In order for terminals to communicate with such a configuration, the transmitting terminal sends information to the transmission line BUS at a timing corresponding to a specific one of the information channels, and the receiving terminal transmits information at the same timing. One-way communication is realized by taking in information from the transmission path BUS. In order to perform full-duplex communication, it is necessary to use two of the above-mentioned misfortune channels.
