Dual access ring configuration

A dual access ring configuration is realized by adding another transceiver that makes the communication
bidirectional. The secondary ring is used as a backup in case the primary ring fails. Data moves in opposite
directions around the rings, and each ring remains independent of the other unless the primary ring fails. The two
rings are connected to continue the flow of data traffic.
