Abstract:
1. A method for operating a network having a ring topology, the method comprising: monitoring a carrier signal, wherein a false carrier indication signal is used to monitor the carrier signal; detecting a faulty connection between two stations of the network by monitoring the carrier signal; and in the event of a faulty connection link, correspondingly rerouting data to maintain a network operation; wherein the network has a contradirectional dual-ring structure, wherein each station of the network has an input interface and an output interface for each ring, and wherein a physical connection between two stations of the network corresponds to an Ethernet standard using electrical data routing, wherein at least one first station monitors the carrier signal at one input interface, wherein, upon detection of a faulty connection, the first station reroutes data from its own output interface, which is connected to an input interface of a second station, to its own input interface, which is connected in a faulty manner to an output interface of the second station, wherein a failure to transmit IDLE codes during a transmission pause generates an invalid code group and causes a response during the monitoring.
