Abstract

PURPOSE:To secure the identification for the slave stations with a simple method without reducing the channel capacity by always inserting the pilot signal for slave station identification allotted to each slave station and then transmitting the pilot signal via the order signal circuit. CONSTITUTION:For the system in which the master station in the multi-direction digital communication network identifies the slave stations, pilot signal oscillator 16 always the pilot signal. And this pilot signal is applied to compounding unit 18 via switch 17 which is constantly closed in case no order signal is transmitted. Then the output received the differential modulation via unit 18 is compounded with the PCM-changed main signal at compounding unit 11 to be then transmitted at all times after the phase modulation through phase modulator 20. While in case the order signal is transmitted, the voice of the order signal is detected by voice detector 15. With this detection output, switch 17 is turned off to stop the pilot signal and transmit the order signal instead. And the pilot signal for the slave station identification is transmitted in case no order signal is transmitted.
