PURPOSE:To decrease the transmission time of data by providing an ACK signal section representing whether the data is received normally or not and transmitting the data from each station to other stations in the lump. CONSTITUTION:Each transmission station gives transmission of the own station respectively on a data part of a frame, and whether or not the transmitted from other stations is received normally in the own station is discriminated based on the own discriminating function and the result is written as ''1'', ''0'' signal on an ACK signal part of the frame. Further, the reception of a frame transmitted before by the other stations is distinguished by a frame number Fi of a header part and whether or not the normal reception is performed is tested by a check byte of an ending part. The frame constituted as shown in A is transmitted in the lump from each station to other stations as shown in B, then the time of data of all the station required for circulation is decreased remarkably. |
