Abstract

본 발명은 전화기의 착신 제어 장치 및 방법에 관한 것으로, 이를 위하여, 링신호 입력을 선택적으로 차단하여 원래의 전화기는 물론 병렬로 연결된 전화기까지도 착신 제어가 가능한 전화기의 착신 제어 장치로서, 링신호의 입력을 차단하는 착신 제어 모드로 선택적으로 전환하기 위하여 사용자의 조작에 의거하여 설정하기 위한 착신 제어 모드 설정부와, 전화기의 통상적인 동작을 제어하며 착신 제어를 위하여 상기 착신 제어 모드 설정부로부터의 설정 신호에 상응하는 모드로 전환하기 위하여 선택 신호를 발생하는 마이크로 프로세서와, 착신 제어 모드가 아닐 경우에 링신호를 정상적으로 입력받기 위한 제1링신호 입력부와, 상기 제1링신호 입력부보다 로우 임피던스로 구성하여 착신 제어 모드일 경우에 링신호를 바이패스시키기 위한 제2링신호 입력부와, 상기 마이크로 프로세서로부터의 선택 신호에 의거하여 상기 제1링신호 입력부와 제2링신호 입력부를 선택적으로 상기 국선 선로에 인가시키기 위한 절체부를 포함하는 전화기의 착신 제어 장치를 제공한다.The present invention relates to an incoming call control device and method of the present invention. To this end, an incoming call control device of a telephone capable of controlling incoming call to a telephone connected in parallel as well as the original telephone by selectively blocking a ring signal input, wherein the ring signal input An incoming call control mode setting unit for setting according to a user's operation to selectively switch to an incoming call control mode to block a call, and a setting signal from the incoming call control mode setting unit for controlling the normal operation of the telephone and for incoming call control In order to switch to the mode corresponding to the microprocessor for generating a selection signal, the first ring signal input unit for receiving the ring signal normally when the call is not in the incoming control mode, and a lower impedance than the first ring signal input unit Second ring ring for bypassing ring signal in incoming call control mode And a switching unit for selectively applying the first ring signal input unit and the second ring signal input unit to the trunk line based on a call input unit and a selection signal from the microprocessor.

또한, 링신호의 입력을 선택적으로 차단하여 수신 제어를 하기 위한 방법에 있어서, 현재 전화기가 사용자에 의하여 착신 제어 모드로 설정되어 있는지를 감지하는 과정과, 착신 제어 모드일 경우에 교환기로부터의 링신호를 바이패스시켜서 병렬로 연결된 타전화기까지도 수신 제어를 할 수 있는 과정으로 이루어진 전화기의 착신 제어 방법을 제공한다.In addition, the method for selectively controlling the reception of the ring signal to control reception, comprising the steps of: detecting whether the telephone is currently set to the incoming control mode by the user; and in the incoming control mode, the ring signal from the exchange. Bypassing to provide a call control method of the telephone consisting of a process that can control the reception even in parallel to other telephones connected in parallel.
