ログ通話信号に変換して、トランク回路1に供給する。The central processing unit 3 containing the exchange processing gummy gram controls the time division communication device 5 via the communication path control device 4 and the trunk circuit 1 via the signal distribution device 2, respectively. The time-division multiplexed speech signal converted by the time-division multiplexed speech converter 5 is transferred to the speech highway by the synchronous multiplex converter 16.
After being distributed to each terminal wJVC1111 in a handling group of, for example, 6 communication paths, it is further time-division multiplexed by the transmission terminal multiplexer 10, and then digital transmission "Nr" (for example, optical fiber or coaxial cable) is transmitted. The transmission terminal multiplexer 11 installed in a remote location receives the signal, time-division demultiplexes it, and sends it to the PCM multiplex converter W.PCM multiplex converter'? / converts the received digital call signal into an analog call signal and supplies it to the trunk circuit 1.
