Abstract

키패드와, 상기 키패드상에 위치된 키에 대응하는 다이얼링톤을 송출하는 다이얼 송출수단과, 외부로부터 수신되는 링신호를 검출하는 링검출수단을 가지는 전화기의 다이얼 송출제어방법에 관한 것으로, 특히 전화 착신에 응답하여 상대방과 통화중인 상태에서 오류로 송출되는 다이얼링톤의 송출을 방지하기 위한 제어방법에 관한 것이다. 상기의 제어방법은 외부로부터 수신되는 링신호의 유무를 검출하는 링검출과정과, 상기 링검출과정에서 링신호를 검출시에 응담하고 오프-훅크하고, 상기 오프-훅크 이후에 입력되는 키패드상의 키신호를 차단하는 키신호 입력 차단과정으로 이루어진 제어과정을 포함하여 구성된다.A dial dispensing control method for a telephone having a keypad, a dial dispensing means for transmitting a dialing tone corresponding to a key located on the keypad, and a ring detecting means for detecting a ring signal received from the outside. The present invention relates to a control method for preventing transmission of a dialing tone that is transmitted in error while in a call with a counterpart. The control method includes a ring detection process for detecting the presence or absence of a ring signal received from the outside, a key on the keypad that is input after the off-hook, responding and detecting the ring signal during the ring detection process. It comprises a control process consisting of a key signal input blocking process for blocking a signal.

Claims

A dial dispensing control method for a telephone having a keypad and a dial dispensing means for transmitting a dialing tone corresponding to a key located on the keypad, and a ring detecting means for detecting a ring signal received from the outside, wherein the ring is received from the outside. A ring detection process for detecting the presence or absence of a signal, and a key signal input blocking process for off-hooking in response to detecting a ring signal in the ring detection process, and blocking a key signal on a keypad input after the off-hook. Error tone transmission prevention control method of the telephone, characterized in that made.

The method of claim 1, wherein the key signal input blocking step comprises: a call path forming step of forming a call path in response to off-hook, a key signal input searching step of searching for an input state of a key signal from the keypad; In the searching process, the key signal is ignored at the time of input, the off-hook searching process for searching whether the operation of the phone is off-hook, and the off-hook searching process until the off-hook status is determined to be determined. The method of claim 1, wherein the method comprises maintaining the communication path and blocking the communication path in response to an off-hook.

The method of claim 1 or 2, further comprising the step of transmitting a dialing tone corresponding to an input of a key signal on the keypad in response to off-hook in the absence of ring detection from the outside. To control the error tone transmission of the telephone.
