Abstract
본 발명은 퍼스널컴퓨터(이하, PC라 약칭함)를 전화기로서 확장하여 사용할수 있도록 해주는 아이에스디엔(ISDN)용 전화기의 확장카드에 관한 것이다.The present invention relates to an expansion card of an ISDN telephone set that allows an extension of a personal computer (hereinafter, referred to as a PC) to be used as a telephone set.
본 발명에 따른 아이에스디엔(ISDN)용 전화기의 확장카드는 핸드셋을 접속하여 외부와 통화를 할수 있도록 해주는 핸드셋접속부와, 모뎀부와 병렬로 외부통신망과 접속되는 망접속부, 장치전체의 제어를 담당하는 중앙처리부, 이 중앙처리부와 퍼스널컴퓨터와의 데이터송수신을 실행하는 코덱부 및 피스널컴퓨터에 동작전원을 공급하기 위한 부가전원부를 포함하여 구성된 것을 특징으로 한다.The expansion card of the ISDN telephone set according to the present invention is a handset connection unit for connecting a handset to make a call with the outside, a network connection unit connected to an external communication network in parallel with a modem unit, and controls the entire apparatus. A central processing unit, a codec unit for performing data transmission and reception between the central processing unit and a personal computer, and an additional power supply unit for supplying operating power to the personal computer.
따라서, 본 발명에 의하면, 기존의 모뎀하드웨어에 일부 하드웨어를 추가하는 것만으로 PC를 전화기로 확장시켜 사용할 수 있게 되므로 PC의 이용효율을 대폭 향상시킬 수 있게 된다.Therefore, according to the present invention, it is possible to extend the PC to a telephone by simply adding some hardware to the existing modem hardware, thereby significantly improving the utilization efficiency of the PC.
