Abstract

PURPOSE:To transmit the high speed data and low speed audio information efficiently, by constituting one frame with the audio information channel, data information channel and control signal channel and constituting one multi-frame with a plurality of frames. CONSTITUTION:In the multiplex frame constitution, time slots 1-64 are transmitted continuously in the order of number, and the time slot taking the column direction of matrix as channel and that for row direction as the frame can be made. Channels 1,9,17-57 and 2,10-58 are taken as control signal channels 1,2 respectively, channels 3,11-59 and 4,12-52 are taken as audio information channels 1,2,3, channels 7,15-63 and 16-64 are taken as data information channels 1,2, each time slot of the data information channel is taken as sub-channels 1-16 to enable the set of communication line in subchannel unit. Control signal is assigned to the audio information channel 1 in the control signal channel 1.
