Abstract
A communication system includes a network, plural nodes, and a reducer. The network includes a main line and a plurality of branch lines branched from the main line respectively, the main line and each of the branch lines being respectively formed into a differential two-wire type of communication line consisting of a first communication line and a second communication line. The plural nodes are connected to two or more branch lines of the plurality of branch lines to communicate frames of data among the branches with each other. The reducer is connected to each node to reduce either an impedance of each of the first and second communication lines or an impedance between the first and second communication lines during a specified period of time starting at a time instant when a node completes sending out frames of data to be transmitted.
