次に動作について説明する。An embodiment of the present invention will be explained below with reference to FIG. 2. This figure shows that a 52 MCMI serial signal is converted into a 4-bit parallel signal, and the signal is transferred by a distribution stage consisting of a low-speed switch of 8 Mbit/s. This is an example of exchanging ◎ In the figure, TIM (1) is replaced with 52M by a known method.
This is a timing circuit that extracts the clock from the CMI serial signal and converts the 32M CMI serial signal into a 4-pit parallel signal using a p-block. TIM(0
) is the opposite of the above, and is a timing circuit for converting a 4-bit parallel signal into a 32MCMI serial signal.
The S/P register is a shift register that converts a serial signal into a 4-bit parallel signal. The P/S register is a shift register that converts a 4-bit parallel signal into a serial signal. Next, the operation will be explained.

る。When the 32MCMI serial signal enters the input terminal of the distribution stage, the input timing circuit: TIM (I) extracts the clock from the 52MCMI serial signal using a known method. ◎This extracted click causes the 87P register to is used to convert the 52 MCMI serial signal into a 4-bit parallel signal. This gives an apparent CMI of 8 Mbit/s.
This is equivalent to slowing down the signal transmission speed. This 4-bit parallel signal, whose signal transmission speed has been reduced, is exchanged using a known method using a distribution stage switch that uses a switching element capable of exchanging 8 Mbit/sec signals. Next, the exchanged 4-bit parallel signal is converted into a serial signal by the output timing circuit: TIM (0) using a P/8 register, and the original signal is converted to a 32MCM signal with a high transmission speed.
I becomes a serial signal and outputs 112! According to this embodiment, the high-speed 32M CMI signal is exchanged using a distribution stage using switching elements capable of exchanging the low-speed 8 Mbit/s signal. I can do it.
