Abstract

PURPOSE:To effieicntly transmit complicated signal, by the multiframe constitution through a plurality of sampling frequencies. CONSTITUTION:One frame consisting of frame bit F, L sets of information words WD, and frame check word FCC is connected in multiple, and the primary multiframe is constituted with M frames, N sets of primary frames constitute the secondary multiframe, and information is transmitted in multichannel. In this case, the frame bit transmitted in the primary multiframe is classified into three types, and they are used for frame synchronism, primary multiframe synchronism and secondary multiframe synchronism.
