Abstract

PURPOSE:To omit the necessity of concentrative management and control for time slots, by using plural transmission lines to multiplex channels at the same timing and by constituting a code, which indicates an idle time slot or the address of a destination station, by signals put on plural transmission lines. CONSTITUTION:Plural stations are connected by loop transmission lines l1-l4 to constitute a loop communication network. In respect to the time division signal format on transmission lines l1-l4, for example, one frame is divided into 6 time slots t0-t5, and data is transmitted at the same timing on transmission lines l1-l4. A frame head pulse is transmitted at the time slot t0, and transmission lines l1-l4 are caused to correspond to 2<0>, 2<1>, 2<2>, and 2<3> respectively at each time slot to constitute binaries 0-15. Value 0 corresponds to an idle time slot, value 15 corresponds to the frame head pulse, and values 1-13 correspond to addresses of destination stations.
