Abstract

1. 청구범위에 기재된 발명이 속한 기술분야 : 전화라인과 접속된 통신단말기에 관한 것이다.1. Field of the Invention The present invention relates to a communication terminal connected to a telephone line.

2. 발명이 해결하려고 하는 기술적 과제 : 전화라인의 전압레벨에 대한 라인 검출 전압이 미리 설정되어 저장된 훅크온전압과 비교하여 이상상태일 시 경보발생하는 전화라인의 이상상태경보 장치 및 방법을 제공한다.2. Technical Problems to be Solved by the Invention The present invention provides an alarm apparatus and method for an abnormal condition of a telephone line in which an alarm is generated when a line detection voltage with respect to a voltage level of a telephone line is abnormal and compared with a hook- .

3. 발명의 해결방법의 요지 : 전화라인과 접속된 통신단말기에서, 상기 전화라인의 전압레벨을 체크하여 라인검출전압을 출력하는 전압검출부와, 미리 체크된 훅크온전압을 구비한 메모리와, 경보표시신호에 의거하여 경보표시하는 표시부에 의거하여 전화라인의 상태를 체크하여 경보하는 제어부의 처리방법은 통화모드가 아닐 시 상기 라인검출전압을 입력하여 상기 훅크온전압과 비교하여 동일하지 않을 시 상기 경보표시신호를 출력하는 과정으로 이룬다.3. Summary of the Solution of the Invention: In a communication terminal connected to a telephone line, a voltage detector for checking a voltage level of the telephone line and outputting a line detection voltage, a memory having a hook- A processing method of a control unit for checking and alerting the state of a telephone line on the basis of a display unit for displaying an alarm on the basis of a display signal is characterized in that when the line detection voltage is not in a communication mode, the line detection voltage is compared with the hook- And outputting an alarm display signal.

4. 발명의 중요한 용도 : 전화라인과 접속된 통신단말기에서 전화라인전압을 체크하여 전화라인의 이상유무를 검출하여 경보하기 위해 이를 구현한다.4. Significant Application of the Invention: It implements this to detect and alarm an abnormality of the telephone line by checking the telephone line voltage at the communication terminal connected to the telephone line.
