Abstract

PURPOSE:To simplify the constitution of a communicating information display circuit, by transmitting a digital code signal corresponding to a dial number from a slave set to a master set (wire telephone subscribing terminal) in a cordless telephone set and introducing this digital code signal to the communicating information display circuit as it is. CONSTITUTION:A slave device 1 transmits a dial number to a master set 3 as a digital code signal (binary signal in 4-bit), the master set 3 converts the said digital code signal into a tone signal at a dial signal generating circuit 34 and transmits it to a subscriber telephone line 4. The master set 3 calculates and displays the call time and its fee with the said digital code signal and the hook information of itself and an opposing station obtained from the monitor of the subscriber lines. Thus, in comparison with a system introducing a dial signal from the line 4 to a display circuit 54, a conversion circuit into a digital signal is not required and the effect of level fluctuation can be avoided, since the radio transmission of the dial signal is made by digital signals.
