Abstract

본 발명은 전화기의 구내전화기 픽업 방법 및 장치에 관한 것으로, 사용자가 다른 구내전화를 픽업하고자할때 송수화기를 들거나 스피커폰 스위치를 누룬 다음 "*"키를 눌러 픽업할수 있는 방법으로 "통화"라는 음성특징을 롬에 미리 저장한 다음 스피커폰 회로도로 부터의 음성신호의 특징을 추출하여 "통화"라는 특징과 비교한 다음 "*"톤을 송출하게 된다.The present invention relates to a method and a device for picking up an extension phone of a telephone. When a user wants to pick up another extension telephone, the user can pick up another handset by pressing a "*" key after picking up a handset or pressing a speakerphone switch. Is stored in the ROM in advance, and the feature of the voice signal from the speakerphone circuit diagram is extracted and compared with the feature of "call", and then "*" tone is transmitted.

Claims

A method for picking up an extension telephone of a telephone, comprising: a first step of storing a voice feature called 'call' in a ROM in advance and extracting a feature of a voice signal; Step 2, if it is not a voice signal such as a voice feature called 'call', connects the speakerphone circuit to the telephone line, and then transmits the '*' tone, and determines whether there is a busy tone or dial tone detected through the tone receiver. The fourth step includes a fifth step of returning to the first step when the busy tone or dial tone is detected, and the sixth step of maintaining the call state if the busy tone or dial tone is not detected and returning to the first step when the call ends. The extension telephone pick-up method of the telephone, characterized in that.

In the telephone circuit, a codec 14 for converting an analog voice signal of the telephone circuit into a digital signal, a voice database ROM 16 for storing voice command features, and a telephone circuit are connected to generate a '*' tone. Tone generator 18, connected to the telephone circuit for controlling the tone receiver 19 for detecting the busy tone or dial tone, the power supply 15, the entire system and the characteristics of the digital voice signal from the codec 14 And a microprocessor (17) for extracting and comparing voice features stored in a voice database ROM (16).
