Ring topology network driving method, ring topology network driving apparatus and network

摘要

The method involves identifying a faulty connection (150-153, 160-163) between subscribers (110,120,130,140) of a network by monitoring a carrier signal. The physical connection between the two subscribers corresponds to Ethernet-Standard data link. False carrier indication signal is used for monitoring the carrier signal, where one of the subscribers monitors the carrier signal. An independent claim is also included for a ring topology network with a device for operating the network with ring topology.
