Claims (3)
- 둘 이상의 모드를 지원하는 라인 인터페이스 장치를 가지는 시스템에서 전송 모드의 자동 설정 방법에 있어서,라인 인터페이스 모드에서 지원 가능한 모드들을 읽어온 후 읽어온 모드들의 순서에 따라 루프 백을 요구하는 테스트 메시지를 생성하고 이를 전송 라인을 통해 출력하는 과정과,상기 출력된 테스트 메시지가 미리 설정된 시간 내에 수신되면 상기 테스트 메시지를 전송한 전송 모드를 상기 라인 인터페이스 장치의 데이터 변환 모드로 설정하고 이를 상기 시스템의 주 제어부로 알리는 과정을 포함함을 특징으로 하는 상기 방법.
- 제1항에 있어서,상기 미리 설정된 시간 내에 루프 백 메시지가 수신되지 않을 경우 상기 모드들의 순서에 따라 다음 모드 설정을 위한 상기 과정들을 반복 수행함을 특징으로 하는 상기 방법.
- 제2항에 있어서,상기 읽어온 모든 모드들에 대하여 모드 설정을 수행한 이후에도 모드를 설정할 수 없는 경우 모드 설정 불가 메시지를 상기 시스템의 주 제어부로 전달하는 과정을 더 포함함을 특징으로 하는 상기 방법.
