N-Link – Configuration

The purpose of N-Link is to provide a way to redundantly couple an N-Ring topology to one or more other

topologies, usually other N-Ring topologies. Each N-Link configuration requires 4 switches: N-Link

Master, N-Link Slave, N-Link Primary Coupler, and N-Link Standby Coupler.
