PURPOSE:To synchronize devices with each other in the frame position, by dividing the frequency of a clock signal transmitting from a higher group multiplexer to obtain a clock signal of a lower group. CONSTITUTION:In the digital signal multiplexing system where the lower group of digital signals to a higher group, the clock frequency of the lower group is set to the 1/P of the clock frequency of the higher group to synchronize devices with each other in the frame position. A clock signal fB from a clock pulse generator 25 of a digital multiplexing device 14 of the higher group is divided to fB/P by a frequency divider 24 and is transmitted to digital transmission devices 11, 12, and 13 of the lower group. |
