Abstract

PURPOSE:To increase an effective data trasmission rate by judging whether data is addressed to a corresponding station or not when a data buffer stores data and then by transmitting stored data to an adjacent station in parallel to reception and storage immediately without waiting for the reception of all data when the abovementioned judgement result is negative. CONSTITUTION:Reception control part 3i deciphers the address part of the format of the frame constitution of received data and when it disagrees with its station address, signal ei showing the existence of received data is outputted immediately. According to this signal, transmission control part 2j extracts data, which is being stored in data buffer 5i, immediately after the transmission of data when there is the data in process of transmission or immediately when there is not the data by controlling address gj and it is converted by transmission part 1j into series information, which is transmitted to the adjacent station via transmission circuit TLj. Thus, the transmission delay at every station can be shortened and the effective data transmission rate can be increased.
