Abstract

본 발명은 종합정보통신망(ISDN) 단말에 해당하는 ISDN 전화기의 호 설정을 위한 인블록(enbloc) 전송방식 구현방법에 관한 것으로서, 전화기 자체의 프리미티브(primitive)를 이용하여 교환기 측으로부터 메세지를 수신하지 않고도 사용자에게 다이얼 톤을 들려주어 착신 가입자 번호를 입력시키도록 하고 사용자가 확인 키를 누를 때까지 교환기 측으로는 아무런 메세지도 전달되지 않도록 하는 바, 전화기내에서 후크 온/오프 상태를 감지하는 제1단계; 상기 제1단계의 결과가 후크 오프 상태이거나 후크 온 상태이면 해당 프리미티브를 구성하는 제2단계; 전화기내에서 상기 프리미티브가 처리되도록 요구하는 제3단계; 및 요구된 프리미티브가 후크 오프 프리미티브이거나 후크온 프리미티브이면 전화기 자체적으로 해당되는 호 제어기능을 수행하는 제4단계를 포함하도록 수행하여 효과적으로 호 설정을 시도하는 것이다.The present invention relates to an enbloc transmission method for establishing a call of an ISDN phone corresponding to an ISDN terminal, and does not receive a message from an exchange side using a primitive of the phone itself. The first step is to detect the hook on / off status within the telephone by telling the user to dial the telephone number without having to enter the called subscriber number without sending a message to the exchange until the user presses the confirmation key. ; A second step of configuring a corresponding primitive when the result of the first step is a hook-off state or a hook-on state; A third step of requiring the primitive to be processed in a telephone; And if the required primitive is a hook-off primitive or a hook-on primitive, the phone itself includes attempting to set up the call effectively by including a fourth step of performing a corresponding call control function.

Claims

Central processing means 100 for controlling the overall function of the phone by using a program that includes hook processing, primitive processing, call control function, ROM 20 in which the program is stored, and RAM for temporarily storing data ( 30), a hook interface means 40 for detecting a hook on / off state, and an analog interface means 50 for providing various loan and voice data to a user. A first step of detecting a hook on / off state in the phone; A second step of configuring a corresponding primitive when the result of the first step is a hook-off state or a hook-on state; A third step of requiring the primitive to be processed in a telephone; And a fourth step of performing a call control function corresponding to the phone itself if the requested primitive is a hook-off primitive or a hook-on primitive.

2. The method of claim 1, wherein the fourth step comprises: a first step of providing a dial tone to a user if the requested primitive is a hook off primitive; And performing a second process of driving display information for dialing.

The method of claim 1, wherein the fourth step comprises: a first step of removing the applied dial tone if the requested primitive is a hook-on primitive; And performing a second process of converting the display information into an initial state.
