The multiple access system for a communication network has a master station (M) connected to several sub-stations via transmission lines. Each of the sub-stations consists of a data buffer that stores data to be transmitted and a request information producing unit that sends a transmission request information including reserved information found based on data quantity stored in the data buffer to the master station. The master station makes a time table of data transmission reservation time based on reservation information included in the transmission request information from the sub-stations, and comprises a control unit that gives data transmission right by sending data transmission permission signal to the sub-stations according to data transmission reservation time of the time table. @(44pp Dwg.No.2/40)@. |
