Abstract
전송 라인의 상태 판별장치를 공개한다. 그 장치는 전송 라인의 상태에 각각 시스템 초기화시에 초기 프레임 동기가 정확히 맞았을 경우 초기 프레임 동기 펄스펄스를 발생하고, 초기 동기가 정확히 맞은 후 어떠한 경우에 의해 동기 에러가 발생된 후에 다시 정상적으로 동기가 맞았을 경우에 라인 검출 펄스를 발생하고, 라인 동기가 어느 기간동안 맞지 않았을 때 발생되는 라인 에러 펄스를 발생하는 인터럽트 소스부; 상기 인터럽트 소스부의 각 펄스 신호에 따라 라인 동기 에러 신호와 프레임(혹은 라인) 동기 신호를 각각 발생하는 인터럽트 발생부; 상기 인터럽트 발생부의 라인 동기 에러 신호 및 프레임(혹은 라인) 동기 신호에 따라 전송 라인 상태 비트를 설정하는 인터럽트 상태 처리부를 구비한 것을 특징으로 한다. 본 발명에 의하면, 전송 라인의 상태를 용이하게 판별할 수 있다.Discloses a transmission line state determination device. The apparatus generates an initial frame sync pulse when the initial frame sync is correctly set at the time of initializing the system in the state of the transmission line, and after the initial sync is correctly set, An interrupt source portion for generating a line detection pulse when the line synchronization is correct and generating a line error pulse to be generated when line synchronization is not performed for a certain period of time; An interrupt generation unit for generating a line synchronization error signal and a frame (or line) synchronization signal according to each pulse signal of the interrupt source unit; And an interrupt status processing unit for setting a transmission line status bit in accordance with a line synchronization error signal and a frame (or line) synchronization signal of the interrupt generation unit. According to the present invention, it is possible to easily determine the state of the transmission line.
