Abstract

PURPOSE:To simply form a dial confirming tone with a good quality, by making tone ringing to a transmitter at a slave station when a call signal is transmitted from a master station and ringing the transmitter of the slave station with a small level at the operation of a touch dial of the slave station. CONSTITUTION:When a callout signal from a master station is received at a reception section 17 of a slave station, a callout tone generating circuit 51 is driven, and the attenuation of an attenuation circuit 52 is controlled to a small value and a tone ringing is made with a transmitter 53. When a touch dial is operated at the slave station, a dial signal is transmitted from a transmission section 14 to the master station, and a call tone generating circuit 51 is driven and the amount of attenuation of the attenuation circuit 52 is greatly controlled, and the dial coinfirming tone is informed from the transmitter.
