Abstract

기존의 퍼스널컴퓨터는 전화벨이 울릴때 마다 컴퓨터가 켜지기 때문에 필요없어 컴퓨터가 켜졌다 꺼졌다 하게 되고, 또한 사용자가 외부에서 데이타통신을 이용하여 자기 컴퓨터를 액세스 할 필요가 있는 경우 외부 침입자에 의해 자기 컴퓨터가 액세스 될 위험성이 뒤따르고 있다.Existing personal computer is not necessary because the computer is turned on every time the phone rings, and the computer is turned on and off. Also, when the user needs to access his computer by using data communication from outside, his computer can be operated by an external intruder. There is a risk of being accessed.

이를 해결하고자 본 발명은 전화벨이 울리는 사이사이에 수신되는 DTMF신호를 CPU로부터 감시하여 미리 동록된 호출자의 동록번호가 수신되었을 때만 컴퓨터에 AC전원을 공급하여 컴퓨터를 자동액티브시킬 수 있게 하는데 있다.The present invention to solve this problem is to monitor the DTMF signal received between the phone ringing from the CPU to supply AC power to the computer only when the caller's phone number registered in advance to enable the computer to automatically activate.
