摘要： A ring network system in which a plurality of line concentrators each having terminal stations connected thereto through respective branch lines are interconnected through at least one ring transmission lines. Each line concentrator includes configuration control switches capable of disconnecting from the ring transmission line all the branch lines placed under control of the line concentrator while holding the ring transmission line in the state to allow communication. The branch line(s) disconnected from the ring transmission line form(s) a local ring through cooperation with an internal transmission line. The line concentrator detected abnormality of communication or the line concentrator to be set to the rest state can undergo internal diagnosis operation or continue to be in the rest state without disturbing the communication among other line concentrators. At activation of the line concentrators, any of them may be activated arbitrarily and independently from each other by again connecting the branch lines to the ring transmission lines.

摘要： In a ring communications system including a plurality of line concentrators that are connected in the form of a ring, the line concentrators are connected together via a main ring, and the terminal stations connected to the line concentrators are connected to the main ring via ring subsidiaries. The main ring and the ring subsidiaries are connected together via ring connection switches that so work as to connect or disconnect the main ring and the ring subsidiaries. The ring connection switch is so constructed as to maintain the connected condition even when the power source of the line concentrator is in the turned-off state.

摘要： In a communication system having first and second ring transmission lines for connecting a plurality of stations and for providing opposite signal transmission direction, a first station, which is located just downstream side of an failure point occurred in the first transmission line, sends out a beacon signal along said first transmission line while causing an intentional failure in the second transmission line on its downstream side and a second station, which is located just upstream side of the failure point on the first transmission line, forms a first loop-back path (WRAPA) by detecting the intentional failure on the second transmission line if the second station has received the beacon signal. The first station forms a second loop-back path (WRAPB) by receiving the beacon from the second transmission line which is sent back by the second station.

摘要： A local area network communication system in which a repeating installation sets a ring number of a ring from which a communication frame was taken out as a source address of the frame. The repeating installation also sets a ring number of a ring to which a communication frame is to be sent. When a station receives the frame, the station checks the source address of the frame to identify the ring number of the ring to which the source station belongs and checks the destination address to identify the ring number of the ring to which the station itself belongs.

摘要： In a communication network having a plurality of stations interconnected through a double ring transmission line, a station which detects a failure in the ring transmission line sends out a failure notice data, and a station which has received the failure notice data stops the send-out of its own data and relays the received data. A station which cannot receive the failure notice data loops back and transmission line to form a closed ring transmission line which bypasses a failure location.

摘要： A method for performing a duplicated address test used for a network including a first ring transmission line, a second ring transmission line having a signal transmission direction opposite to that of the first ring transmission line, and a plurality of stations connected to at least one of these ring transmission lines. Each of these stations has a flag DAC representing whether or not the duplicated address test is performed, and some of the plural stations constitute a plurality of control nodes having a configuration function of the network. The flag DAC of each of the stations is reset at a time instant when a power source of this station is turned on, and also when any of the control nodes receives the sent out configuration control frame. Each of the stations having the reset flags DAC sents out the duplicated address test frame to either the first or second transmission line to which the station is connected when a token frame to control a transmission right is captured. When another station having the same address as that of a source station receives the test frame, a discriminator indicative of an address duplication is added to this test frame.
