Abstract

PURPOSE:To simplify hardware by fixedly allocating free time slots for communication only when time slots are to be used. CONSTITUTION:Loop transmission line 4 is provided with time slot control part 5 and nodes 6-1-6-i. To respective nodes, DTE parts 3-1, 3-2-3-i, such as a computer and terminal device, are connected. Through this loop transmission line 4, frame data of constitutions roughly classified into time slot group I used for communication between the nodes and time slot control part 5 and time slot group II used for communication between nodes. Time slot control part 5 decodes a node request from a node to store the inuse state of the time slots and, when a request for communication from one node to another node is sent, allocates time slots required for that, so that the transmission line can effectively be used.
