Abstract

In a multiple access system for a communication network in which a main station (M) is coupled to a plurality of sub stations (S1-Sn) via lines, each sub station (S1-Sn) comprises a data buffer (1) for storing data (DATA-TE) which is to be transmitted, and a request information forming part (2) for sending to the main station (M) transmission request information (REQ) which includes reservation information obtained based on a data quantity (IN) stored within the data buffer, and the main station (M) comprises a control part (5) for forming a time table (3) of a data transmission reservation time and a corresponding sub station number based on the reservation information included in the transmission request information from each sub station and for giving authority to transmit data to each sub station by transmitting a data transmission enable signal (TENO) to each sub station depending on the data transmission reservation time and the sub station number of the time table.
