Multi-lane transmission system, multi-lane transmission equipment, and multi-lane transmission method

摘要

An object of the present invention is to notify a change in the physical lanes in multi-lane transmission system. A first frame processing unit 11 of the multi-lane transmission apparatus 1 is to map the client signal to the payload, and outputs the frame added with overhead. Monitoring control unit 10 rewrites a portion of the overhead, the information indicating that the overhead capacitance change notification is set, the capacity change notification for overhead containing information indicating a logical lane usage schedule. Coding and scrambling unit 12, a transport frame generated by performing error correction coding on the frame, scrambles except a predetermined region including the information indicating that the overhead capacitance change notification has been set. Lane distribution part 13 distributes by dividing the scrambled transport frames into blocks in a plurality of logical lanes. Tx14-1~14-4 sends to the physical lanes by multiplexing the blocks that are distributed to a plurality of logical lanes. .BACKGROUND
