Abstract
본 발명은 교환 시스템의 신호 재전송 방법에 관한 것으로, L2기능을 구현하는 시스템에서 L1기능이 정상적으로 유지되지 못한경우 이의 정상적인 수행을 위해서 전송로 정보상태를 알수 있는 내부상태 레지스터를 이용하여 일정시간의 과도시간 지연후 유실된 최종전송 메시지를 재전송하여 L2 상태가 유휴로 천이되는 것을 방지하여 전송로가 복원되는 시점에서 바로 서비스를 받을 수 있도록 함과 동시에, 메시지 신호 유니트 전송도중 링크가 완전히 유실되었다 할지라도 타이머를 이용 재전송방식을 사용함으로써 신뢰성이 있는 데이타 송, 수신이 수행되도록 하는 방법을 제공한다.The present invention relates to a signal retransmission method of an exchange system, and when the L1 function is not normally maintained in a system implementing the L2 function, a transient for a predetermined time using an internal state register for knowing the transmission path information state for the normal execution thereof. Resend the last transmission message lost after a time delay to prevent the L2 state from transitioning to idle so that service can be received immediately when the transmission path is restored, and even if the link is completely lost during transmission of the message signal unit. By using a retransmission scheme using a timer, a reliable data transmission and reception is provided.
