Abstract

본 발명은 다이얼음을 검출하여 통화료를 구성하는 장치 및 방법에 관한 것으로, 일반적인 무선전환기는 국선을 연결하지 않은 상태에서 전원을 공급한 후 휴대장치(나)에 통화시작 코드가 송출되면 고정장치(가)가 동작하므로 사용자가 국선의 이상상태를 모르는 문제점이 있었다.The present invention relates to a device and a method for configuring a call charge by detecting a dial tone, and a general wireless converter is provided when a call start code is transmitted to a mobile device (b) after supplying power without connecting a trunk line. There is a problem that the user does not know the abnormal state of the trunk line.

본 발명은 다이얼음 인식부(150)를 고정 장치(가)에 구비하여 링신호가 들어올때는 다이얼음을 인식하지 않고 통화모드로 되게 하는 다이얼음을 검출하여 통화로를 구성하는 것으로 통화시 국선의 이상 유.무를 검출하기에 적당한 발명이다.The present invention comprises a dial tone recognition unit 150 in the fixed device (A) to detect the dial tone to enter the call mode without recognizing the dial tone when a ring signal is input to configure the communication path of the CO line during the call It is an invention suitable for detecting the presence or absence of abnormalities.

Description

다이얼음을 검출하여 통화로를 구성하는 장치 및 방법Apparatus and method for configuring a call path by detecting a dial tone

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 고안 무선 전화기의 고정장치(가) 및 휴대장치(나)의 구성 블럭도,2 is a block diagram of the fixing device (a) and portable device (b) of the present invention wireless telephone,

제3도는 본 고안을 구현하기 위한 다이얼음 검출 회로도.3 is a dial tone detection circuit diagram for implementing the present invention.

Claims (3)

입력다이얼음을 일정 주파수만 통과하도록 필터링하는 필터부(31)와, 상기 필터부(31)로부터 필터링된 신호를 필터 정류하는 필터정류부(32)와, 상기 필터정류부(32)로부터 출력된 신호와 기준전압(VDD)을 비교하여 그 결과 전압으로 다이얼음을 검출하는 비교검출부(33)로 구성됨을 특징으로 하는 다이얼음을 검출하여 통화로를 구성하는 장치.A filter unit 31 for filtering the input dial to pass only a predetermined frequency, a filter rectifying unit 32 for filter rectifying the signal filtered by the filter unit 31, and a signal output from the filter rectifying unit 32; And a comparison detecting unit (33) for comparing the reference voltage (V DD ) and detecting the dial tone with the resultant voltage. 고정장치(가)에 다이얼음 유무를 검출하는 다이얼음 인식부(150)를 구비하여, 링신호가 검출되면 다이얼음을 인식하지 않고 통화 모드로 하고, 통화시작 코드가 입력되면 국선을 루프하여 다이얼음을 검출하고 이후, 확인 코드를 송출하여 통화모드로 하고, 상기에서 다이얼음이 일정시간내에 입력되지 않으면 확인코드를 송출하지않고 초기 대기상태로 됨을 특징으로 하는 다이얼음을 검출하여 통화로를 구성하는 방법.The fixed device includes a dial tone recognition unit 150 that detects the presence or absence of a dial tone. When a ring signal is detected, the dialing device recognizes the dial tone and enters the call mode without recognizing the dial tone. After detecting the ice, the confirmation code is sent out to enter the call mode, and if the dial tone is not input within a predetermined time, the call path is formed by detecting the dial tone, which is characterized by an initial standby state without transmitting the confirmation code. How to. 휴대장치(나)는 통화키가 입력되면 채널을 탐색하고 송신부를 동작시키며 통화시작 코드를 송출하고 이후, 확인코드 입력 여부를 판단하여 그 결과 확인 코드입력이면 통화모드를 만들고, 상기에서 확인 코드가 일정시간동안 입력되지 않으면 다이얼음이 검출되지 않는 것으로 판단하여 처음의 대기상태로 됨을 특징으로 하는 다이얼음을 검출하여 통화로를 구성하는 방법.When the call key is input, the portable device searches for a channel, operates a transmitter, sends a call start code, and then determines whether to enter a confirmation code. And if no dial tone is detected for a certain period of time, determining that the dial tone is not detected, thereby establishing a call path. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
