Abstract

본 발명은 키폰전화기의 다이알톤 유무 경보장치에 관한 것으로, 키폰전화기에 있어서, 국선을 사용할 시 종래에는 국선을 통해 다이알톤을 유무를 검출하여 다이알톤이 검출되면 정상적인 동작을 계속하고, 다이알톤이 검출되지 않으면 아무런 메시지 없이 동작을 멈춘다. 따라서 관련지식이 없는 사람이 키폰전화를 이용할 경우 아무런 메시지 없이 전화통화가 안되면 여러차례 국선을 사용하려는 시도를 계속하거나 주위사람에게 도움을 청하여 이상상황을 극복하려고 많은 시간을 소비하는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 국선 사용시 다이알톤이 없으면 이를 음성신호를 사용자에게 알게 함으로써 관련지식이 없는 사람도 이상상황을 즉시 알 수 있게 한 키폰전화기의 다이알톤 유무 경보장치를 창안한 것이다.The present invention relates to a dial tone alarm device for a key telephone telephone. In a key telephone telephone, when a trunk line is used, a conventional dial tone is detected through a trunk line, and when a dial tone is detected, the normal operation is continued. If not detected, operation stops without any message. Therefore, if a person who does not have related knowledge uses a phone phone and there is a problem that the phone call is not made without any message, there is a problem in that the user spends a lot of time trying to overcome the abnormal situation by continuing to attempt to use the trunk line several times or by asking the people around for help. The present invention is to solve the problems of the prior art by using a dial-up line when there is no dial tone when the user knows the voice signal to the user without the relevant knowledge invented a dial tone alarm device for the presence of a dial phone phone that can immediately know the abnormal situation will be.
