Abstract

PURPOSE:To allow an asynchronizing terminator to be connected to a PCM transmission line sending signals of various speeds by transmitting/receiving a data signal while applying speed conversion to the signal. CONSTITUTION:A PLL circuit 100 to obtain a basic clock from a PCM transmission line, a timing generating circuit 200, and a mapping circuit 300 receiving a data signal from the terminator, and applying mapping to match the data transmission speed of the signal with that of the PCM transmission line, are provided. Moreover, a speed conversion use transmission register 60 to converts the output of the circuit 300 into the output with the speed designated to the PCM transmission line, a reception register 80 receiving the data signal sent through the PCM transmission line and outputting the data having the data speed required for the terminator, and a de-mapping circuit 400 to receive the said output and to send the data subject to de-napping to the terminator, are provided. Thus, the data of the terminator are communicated asynchronizingly through various PCM transmission lines having diversified data transmission speeds.
