Abstract

PURPOSE:To ensure the reliability of the node and to carry out a large amount of aural communication with high efficiency, by setting a node as the master node with other nodes set as the slave nodes and performing the control for the slot of a circuit network through the master node. CONSTITUTION:Each of nodes N1 plus N2-Nn contains an optical transmitter T and an optical receiver R. The transmitter T is connected to the input terminal of a star coupler S, and the receiver R is connected to the output terminal of the coupler S respectively. Thus the optical transmission lines are formed with optical fibers F among the nodes N1 plus N2-Nn. Then a node is set as the master node, and accordingly other nodes stop the function of a master node and function as the slave nodes. At the same, the slot of a circuit network is controlled by the node functioning as the master node. In such way, a large amount of aural communication can be carried out with high efficiency without collision.
