A network architecture for use in a data traffic network that includes a plurality of nodes and a plurality of data links coupling the nodes. The network architecture includes a working data link(220) that forms a signal pathway between a first router (200) and a second router (210) within the network. A protection data link(255) is likewise provided and forms a second signal pathway. The routers (200, 210) include both working data ports (312) and protection data ports (314) with each port including associated transmit and receive terminals. A combination of line splitting devices (250), line selection devices (260) and switch arrays (430, 435) are used to switch the flow of traffic data from the working data link (220) to the protection data link (255) or a protection channel (450) as is appropriate.
