Abstract

An occupation signal is provided from the sender exchanger(1) thru relays to the relay station exchanger(2), then the receiving tone detector(6a) detects an occupational signal and transmits to the relay station exchanger(2). The relay station exchanger(2), by the dial information of the sending station exchanger(1) transmits the occupational signal to the receiving station exchanger(3) thru coder, and decoder(5b). The transmission tone detector(7b), detecting the detection signal transmitted to the receiving station exchanger(3) from the coder, decoder(5b), transmits ring back tone signal to the relay station exchange. When receiving station's customer's replies, transmits reply signal to the relay station exchanger.
