Abstract

PURPOSE:To equally give the occupied right of line to all the stations in the line, by turning the priority of line occupancy to a given direction without fixing the station having highest priority, relating to the occupancy of line. CONSTITUTION:When the station transmitting the line occupancy command receives the line occupancy command from other station having transmission request, if P.ADR of line occupancy command of the station itself is in agreement with that of reception, P.ADR is turned toward the arrow. If the station itself is nearer to P.ADR, it is regarded that the station itself has higher line occupancy than other station and the transmission to the station at the down stream of the line occupancy command received is stopped and the line occupancy command from other station is removed from the line. If the line occupancy command of other station is near to P.ADR, it is regarded that the other station has higher priority than the station itself and the received command is transmitted to the down stream side.
