PURPOSE:To efficiently multiplex many data lines by executing the using method in which 24 frames are made into one multi-frame and a special effective speed is obtained per one frame. CONSTITUTION:For one frame composed of 8 bits b1-b8, 24 frames are continuous and one multi-frame is constituted. The period of a frame is 125musec, and the period of one multi-frame goes to 125musecX24=3msec. At the time of multiplexing, one frame in respective multiframes is taken out and one super frame is constituted of 5 frames composed of frames S1-S5. By the frame S1, a synchronizing signal C1 is accommodated to a bit b1 and the data are accommodated to bits b2-b8. In this case, the period of one super frame is 3msecX5=15msec, the data of 36 bits are accommodated in one super frame, therefore, the data quantity, which can be accommodated, goes to 36 bitsX/15 msec=24kb/s and many data lines can be efficiently multiplexed.
