4.2 Coupling Ring Application

In the network, it may have more than one X-Ring group. By using the coupling ring function, it can connect each X-Ring for the redundant backup. It can ensure the transmissions between two ring groups not to fail.The following figure is a sample of coupling ring application.The couple ring consists of four switches—switch 1 ~ switch 4—which are connected to each other via the paths in red. Please note that the Coupling Ring Backup Path between switch 1 and switch 3 is blocked; it will work only when the path between switch 2 and switch 4 is broken or disconnected.
