WIRE/WIRELESS KEY TELEPHONE SYSTEM

PURPOSE: A wire/wireless key telephone system is provided to add a wire communication function to a repeater, so that a user who is not necessarily connected to a wireless telephone can use a cheap wire telephone and a user who has a difficulty in connecting a telephone line can use a wireless telephone. CONSTITUTION: An antenna receives a radio wave of a repeater transceiver. The radio wave is transmitted to a wireless transceiving controller(17). The radio wave is converted into a voice signal through a coder-decoder(CODEC)(33) under control of a CPU(18), and transmitted to a speaker(32) of a telephone receiver. A caller voice is inputted through a microphone(34), and converted into a digital signal through the CODEC(33). The digital signal is converted into a radio wave through the wireless transceiving controller(17), and transmitted to a repeater. The repeater transmits the radio waves of the antenna and a transceiver to other party. A central controller senses a telephone dial(38) and a speaker phone dial(39) to transmit dial tones, and receives an input signal of sensing switches(42). Power supplied from a charging battery(36), a solar panel(37), and an external power supplying socket(40) is supplied to a telephone body. An RS-232C port is connected to a wireless telephone, to perform data communication between a telephone and a computer. A telephone program is stored in a ROM(27), and inputted to the CPU(18) through a ROM controller(26). A user inputs a required menu or a telephone number in the CPU(18). Inputted key information is coded through a keyboard controller(25). A processed result is displayed on a liquid crystal display(LCD) screen through an LCD controller(29).
