KR950035259A - Automated pager interconnected with pager - Google Patents

Abstract

The present invention relates to an automatic pager interconnected with a pager, and includes a frequency sensing unit for detecting that a telephone call is received and receiving a touch-tone signal from a sender, and receiving a microcomputer control of the telephone when the telephone is received. A switch and buffer unit connected to an internal speaker to drive the speaker and a microphone, a display and keyboard unit for receiving a user's command through an input key of a keyboard and displaying a current state under the control of a microcomputer, and stored in a memory A D / A converter for receiving digital voice content through a microcomputer and converting it into an analog signal, a frequency generator for generating a touch-tone signal according to a sender's input signal, the D / A converter and a frequency generator Low pass filter to remove the high frequency noise generated in the Chi-output amplifier section for transmitting the tone signal, a memory that stores the identification number of a pager associated with the telephone, and running the program for transmitting a telephone number that is input in response to the control of the microcomputer from the external to the radio pager and; A speaker for outputting a voice signal and a call answer signal to the outside; The switch and buffer unit, the memory, the display and keyboard unit, and the microcomputer to control the frequency generator, the user can know the telephone number of the caller even when the call is absent in the absence of the user through a wireless pager Not only can they exchange information instantly, but they can also immediately contact people who do not know the number of their pager.
