Abstract

PURPOSE:To improve the high frequency characteristic of a voice signal by using a low frequency at the outside of the voice band for a tone signal for transmission control such as circuit connection and using a high frequency for a tone signal or dial oscillation so as to increase the modulation of the voice signal. CONSTITUTION:When a person of a slave set 2 closes a calling switch 24 and responds to a call, the 1st tone signal f1 of a low frequency at the outside of the voice band is sent. A maser set 1 receiving the signal f1 makes communicetion with the slave set 2 through an external line mutually by the detection of the signal f1 by a 1st tone signal detection circuit 10. In outgoing a call from the slave set 2 to a line wire, the switch 24 is closed and a relay contact 16' is closed by sending the signal f1, a pulse is generated by a dial signal generating circuit 26 and a 2nd tone signal f2 in 5kHz generated by a 2nd tone signal generating circuit 27 is sent in response to the pulse. Thus, the modulation of the voice signal is increased and the high frequency characteristic of the voice signal is improved.
