が膨大となり大形化を免れ得ない。In the above-mentioned conventional time division communication channel equipment, as the number of terminals accommodated in the time division electronic exchange increases, the lower PCM
Since the degree of time division multiplexing on the highway and the PC-M highway increases proportionally, it is necessary to increase the transmission speed of digital speech signals on the PCM highway. Furthermore, as the number of terminals increases, the physical size of the time-sharing electronic exchange itself also increases, and the physical length of the PCM highway increases. In order to correctly transmit signals over the extended PCM highway, it is sufficient to convert the digital call signals into serial-to-parallel signals and transmit them as parallel digital call signals over the PCM highway. Since the number of highways is large, digital communication signals of the product of the number of parallel bits and the number of PCM highways are input to the highway switch, which increases the number of input signal terminals of the highway switch and inevitably increases the size of the highway switch.
