RING TYPE LAN HAVING FAULT PROCESSING SYSTEM A ring type LAN with a fault processing system which detects a faulty station when a logical fault occurs at any of a plurality of stations making up the ring type LAN and which further restores the ring type LAN, which provides at each station at least a timer for measuring the transmission time of a beacon frame or other fault notifying frame and, when the timer runs out of time, forms a loopback or bypass with the adjoining station, temporarily removes the stations from the ring, has the removed stations detect by themselves if they are normal, and, when the results of detection are that they are normal, once again incorporates the stations, other than the one for which the time has run out, into the ring, thus finally rebuilding the ring type LAN in a state with just the faulty station removed from the ring.
