Abstract

1. 청구범위에 기재된 발명이 속한 기술분야: ISDN 전화기에 관한 것으로, 특히 통화형성중 내부에서 호를 전이시킬 수 있는 ISDN 전화기 및 그 방법에 관한 것이다.1. TECHNICAL FIELD OF THE INVENTION The invention described in the claims relates to ISDN telephones, and more particularly, to ISDN telephones and methods capable of transferring calls internally during call establishment.

2. 발명이 해결하려고 하는 기술적 과제: ISDN 교환기의 이용없이 전화기 내부에서 호를 전이시킬 수 있는 장치 및 방법을 제공함에 있다.2. The technical problem to be solved by the present invention is to provide an apparatus and method for transferring a call inside the phone without the use of an ISDN switch.

3. 발명의 해결방법의 요지: 국설 ISDN 교환기로부터 입력되는 데이터신호를 인터페이싱하는 제1인터페이싱 수단과, 아나로그 전화기와의 통화수행을 위해 데이터인터페이싱하는 제2인터페이싱수단과, 퍼스널컴퓨터와의 통화수행을 위해 데이터인터페이싱하는 제3인터페이싱수단을 구비하는 ISDN 전화기에 있어서, 상기 ISDN 교환기와 통화형성중에 입력되는 호 전이 명령에 응답하여 상기 인터페이싱수단을 선택하기 위한 제어신호를 생성출력하는 제어수단과, 상기 제어신호에 의해 호 전환 스위칭 동작하여 통화를 수행할 수 있는 통화스위칭수단을 구비함을 특징으로 한다.3. Summary of Solution of the Invention: First interfacing means for interfacing data signals input from a national ISDN exchange, second interfacing means for interfacing data for conducting a call with an analog telephone, and a call with a personal computer. An ISDN telephone having a third interfacing means for interfacing data for the purpose of communication, comprising: control means for generating and outputting a control signal for selecting the interfacing means in response to a call transfer command input during the call establishment with the ISDN switch; And a call switching means capable of conducting a call by performing a call switching switching operation by a control signal.

4. 발명의 중요한 용도: 국선 ISDN 교환기와 연결되어 사용되는 ISDN 전화기의 호 전이방법에 사용될 수 있다.4. Significant use of the invention: Can be used in the call transfer method of ISDN telephones used in conjunction with trunk line ISDN exchanges.
