Abstract:
1. A transport system comprising: time division multiplexing means for applying time division multiplexing of a whole signal of a client including client overhead transparently; attaching means for attaching an additional overhead to said whole signal of said client; and wavelength division multiplexing transporting means for transporting a time-division-multiplexed signal represented by one wavelength containing said additional overhead from one network to another network by applying wavelength division multiplexing, wherein said additional overhead contains bits defining frame synchronization or channel selection, and an insertion cycle of said bits is shorter than a frame cycle of client signals, wherein said additional overhead contains bits defining error correction, and said system performs error correction, wherein said additional overhead contains bits defining data storage for applying negative stuffing to adjust a frequency of a client clock, and positive stuffing is applied by inserting said bits in a payload, wherein said additional overhead contains bits defining stuffing information, and wherein said time division multiplexing is based on bit interleaving or byte interleaving.
