ABSTRACT:
N framing units block N-channel input digital signals, respectively, to provide blocked signals. The framing units respond to a common block synchronization signal from a multiplexing unit to provide the blocked signals in a time relation suitable for multiplexing. The multiplexing unit multiplexes the blocked signals from the framing units to provide a multiplexed signal (higher-order group signal).
