ABSTRACT:
In each low-rate interface 1, a clock/frame pulse signal 16 is separated from a signal 11 outputted from a high-rate interface and coupled through a phase controller 6 for clock substitution in a clock substituting circuit 5. The phase controller 6 sets a phase delay as a result of design when making evaluation such that the phase of a signal 13 inputted to an exchanger 7 is coincident with the phase of its output signal 12. Thus simplifying the clock supply to low-rate interfaces in a multiplex transmission system, in which housings of a high-rate interface and the low-rate interfaces are physically separate from one another.
