PURPOSE:To make it possible to use a time-division multiplex transmitter universally, by setting a time slot of random length at a random position in a frame, by freely fixing a frame pattern and bit position. CONSTITUTION:At the transmission side of the multiplex transmitter, input signals 61-81 from respective channels are stored in buffer memories 65-85 temporarily with clocks 60-80 indicating transmission speeds of respective channels, and on the basis of clock 11 from clock generating circuit 1 and frame synchronizing signal sending signal 21 from frame pattern generating circuit 2, time slot setting circuits 5, 7 and 8 generate slot position signals 62-82 for the signals of respective channels with prescribed time slots and then send them to multiplexing circuit 3. Simultaneously, they are inputted to memories 65-85 and at assigned time slot positions, they are read out respectively and sent to multiplexing circuit 3, which transmits each readout signal to multiplex transmission line 4 with a synchronizing signal, etc., from frame pattern generating circuit 2. |
