Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

팩시밀리에서 데이타 전송속도 자동 조절 방법.How to Automatically Adjust the Data Transfer Rate in a Facsimile.

2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention

종래에는 TCF신호의 0 데이타만으로 전송속도를 결정하므로 선로상태가 나쁜 상태에서도 고속으로 데이타가 전송될 수 있어 수신 에러 발생 또는 데이터의 찌그러짐이 빈번하게 발생되었다.Conventionally, since the transmission rate is determined only by 0 data of the TCF signal, data can be transmitted at a high speed even in a bad line state, resulting in frequent reception errors or data collapse.

3. 발명의 해결 방법의 요지3. The point of the solution of the invention

문서 전송을 위해 프로토콜 진행시 수신되는 트레이닝 체크신호의 레벨을 검출하여 검출된 레벨에 적정한 데이타 전송속도가 설정될 깨까지 라인 트레이닝 실패신호를 송출하여 자동으로 데이타의 전송속도를 조절하는 방법.A method for detecting a level of a training check signal received when a protocol is transmitted to transmit a document, and transmitting a line training failure signal until a proper data transmission speed is set for the detected level, thereby automatically controlling the data transmission speed.

4. 발명의 중요한 용도4. Important Uses of the Invention

팩시밀리.Facsimile.

Claims (4)

팩시밀리에 있어서, 문서 전송을 위해 프로토콜 진행시 수신되는 트레이닝 체크신호의 레벨을 검출하여 검출된 레벨에 적정한 데이타 전송속도가 설정될 깨까지 라인 트레이닝 실패신호를 송출함을 특징으로 하는 자동 데이타 전송속도 조절방법.A facsimile apparatus according to claim 1 or 2, wherein a level of a training check signal received when a protocol is transmitted for document transmission is detected and a line training failure signal is transmitted until a proper data transmission rate is set for the detected level. Way. 제1항에 있어서, 상기 레벨 검출은, 상기 트레이닝 체크신호의 레벨을 소정의 설정된 기준 레벨에 비교하여 적정의 전송속도를 결정함을 특징으로 하는 자동 데이타 전송속도 조절방법.The method of claim 1, wherein the level detection is performed by comparing a level of the training check signal with a predetermined reference level to determine a proper transmission rate. 제2항에 있어서, 상기 전송속도 설정은, 라인 트레이닝 실패신호에 응답하여 상기 결정된 전송속도의 설정을 요구하는 트레이닝 체크신호가 수신되면 수신준비신호를 송출함을 특징으로 하는 자동 데이터 전송속도 조절방법.3. The method of claim 2, wherein the transmission rate setting comprises sending a reception ready signal when a training check signal requesting the setting of the determined transmission rate is received in response to a line training failure signal, . 프로토콜에 의해 전송속도가 설정된 팩시밀리에서 라인 상태에 따라 전송속도를 조절하는 방법에 있어서, 수신된 트레이닝 체크신호의 레벨을 체크하는 레벨검출과정과, 상기 검출된 트레이닝 체크신호의 레벨에 상기 설정된 전송속도가 적정한가를 판단하는 비교과정과, 상기 설정된 전송속도가 부적정할 경우 라인 트레이닝 실패신호를 송출하는 전송속도 변경요구 과정과, 상기 설정된 전송속도가 적정하거나 상기 전송속도 변경요구에 응답하여 소정의 트레이닝 체크신호가 수신되면 수신준비신호를 송출하는 데이터 전송요구 과정으로 이루어짐을 특징으로 하는 자동 데이타 전송 속도 조절방법.A method of controlling a transmission rate according to a line status in a facsimile in which a transmission rate is set by a protocol, the method comprising: a level detecting step of checking a level of a received training check signal; A transmission rate change requesting step of transmitting a line training failure signal when the set transmission rate is inappropriate, and a transmission rate change requesting step of, when the set transmission rate is appropriate or in response to the transmission rate change request, And a data transmission requesting step of sending a reception ready signal when a signal is received. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
