Abstract
본 발명은 LCD가 없는 광 다이알을 내장하고 있는 무선 전화기에서 발신 전화 번호의 확인을 가능하게 하는 발신 전화 확인 회로 및 그 방법에 관한 것이다.The present invention relates to an outgoing call confirmation circuit and method for enabling verification of an outgoing call number in a cordless telephone having an optical dial without an LCD.
본 발명은 발신 전화번호를 다이알하기 위한 텐키 및 확인키가 구비된 키패드와, 상기 키패드의 키입력에 따라 해당 제어 신호를 출력하는 CPU와 상기 키패드에서 발신 전화 번호의 다이알 버튼 입력 후 확인키를 누르면 상기 CPU의 제어에 의해 먼저 입력된 순서대로 다이알 버튼의 해당 LED를 일정시간 차례로 점등시키는 LED구동부와, 확인키가 입력되면 상기 CPU의 제어에 의해 오프되어 키패드의 데이타가 라인으로 송출되지 않도록 제어하는 라인 송출 데이타 제어부로 구성되어, 발신 전화 번호의 다이알 버튼 입력 후 확인키를 누르면 입력된 순서대로 해당 LED를 일정시간 차례로 점등시키으로써, 다이알 버튼의 정확한 입력 여부를 확인할 수 있게 되어 재다이알링하는 시간의 낭비를 없앤다.According to the present invention, a keypad provided with a ten key and a confirmation key for dialing an outgoing telephone number, a CPU for outputting a corresponding control signal according to a key input of the keypad, and pressing a dial key of an outgoing telephone number from the keypad are pressed. The LED driver for turning on the corresponding LEDs of the dial buttons in order for a predetermined time in the order inputted first by the control of the CPU, and when the confirmation key is input, the LED is turned off by the control of the CPU to control the data of the keypad not to be sent to the line. It is composed of a line transmission data control unit.If you press dial button of outgoing telephone number and press OK key, the corresponding LED is turned on for a certain time in the order entered, so you can check whether dial button is correct or not. Eliminates waste.
