Versatile Multiplexing Based on Hunting-Free Framing

Application of multipled block codes (MBCs) for realizing new, flexible and versatile multiplexing is investigated. First, the principles of MBC are overviewed to show its capacities of filterless clock recovery. Then it is shown that modification of simple frame structure of MBC line code can be used for attaining hunting-free reframing for multiplexing systems. Finally, the applicability of hunting-free reframing to versatile multiplexing is investigated. An example of broadband ubiquitous subscriber distribution in terms of versatile multiplexing is discussed.
