4.4 Dual Ring Application

Dual ring is the advanced function that supports backup connection for transmission

redundant purpose. While the connection fails, the system will recover from failure within

20 milliseconds. Apart from that, Dual Ring only needs one unit (and only the one

located in the middle) to be configured as the Ring Master switch to deploy the dual ring.
