ABSTRACT:
In order to improve the throughput of an a-point to multi-points information system having a master station for transmitting an a-point to multi-points frame and a plurality of slave stations for receiving the a-point to multi-points frame and to insure reliability of received information, the master station comprises a unit for detecting that the number of slave stations which are in abnormal receiving of an a-point to multi-points frame from the master station exceeds a predetermined value, and retransmits the a-point to multi-points frame received abnormally during the detection. When the slave stations are divided into a plurality of groups, the master station comprises a unit for detecting that the number of slave stations in each group which are in abnormal receiving of an a-point to multi-points frame from the master station exceeds a value which is predetermined for each group, and retransmits the a-point to multi-points frame after temporarily disconnecting slave stations in a detected group from the object to which the a-point to multi-points frame is transmitted from the master station.
