A communication network (100) is described. The network includes communication media (150, 160) and a plurality of network nodes (120, 122, 124, 126, 128, 130, 132, 134) coupled by the communication media (150, 160). Each of the plurality of network nodes (120, 122, 124, 126, 128, 130, 132, 134) includes a first communication channel (150) and a second communication channel (160). The first communication channel (150) includes a first physical layer transceiver (PHY device) and the second communication channel includes a second PHY device. The plurality of network nodes (120, 122, 124, 126, 128, 130, 132, 134) are coupled in a dual ring- type topology. |
