Self Healing Ring Configuration
This configuration can be achieved by connecting the unused fiber optic ports of the
first and last NOM25200 directly or through the fiber optic repeater, if a mixed fiber
optic/twisted pairs network is used. This type of connection has all the advantages
of the previously described configurations, along with built-in redundancy. A broken
connection between any two Quantum modules in the ring will automatically
reconfigure the network to the Bus Configuration and continue the communication.
