Abstract

PURPOSE:To make it possible for each station to have communication efficiently without interference from other stations by providing each station with one transmitting circuit and receiving circuits as many as party stations separately in a communication system consisting of not less than three stations connected and giving addresses of their offices to receiving circuits. CONSTITUTION:Stations 41, 42 and 43, having mutually-independent transmitting circuits 51, 52 and 53, receive only messages with the same appended address indicated by 61, 62 and 63. Now, station 41, when to communicate with station 42, adds B a message to be sent out of station 41 and A' to an answer from station 42. To a message to be sent out of station 42, A is appended and to an answer from station 42, B' is added. Consequently, even if stations 41 and 42, and 42 and 43 start communication at the same time, messages addressed to respective stations are separable and the communication can be carried out without contradiction. Further, even when stations 41 and 42 start communication with stations 42 and 41, the communication can be attained independently. Therefore, each station can have communication efficiently without interference from other stations.
