Abstract
본 발명은 동기식 광전송장치의 분기결합(ADM)망에 있어서 링 경보방법에 관한 것으로 상기 네트웍에 연결된 노드들이 초기화하는 단계(200∼203); 상기 각 노드가 동기식 다중화 프레임의 구간오버헤드에 속하는 F1바이트를 읽어오는 단계(204); 상기 F1바이트를 검사하여 경보를 판단하는 단계(205); 상기 판단결과 경보가 검출되면 디엠에이(DMA)상태로 셋하고, 링경보비트(RING_ALM_BIT)를 셋하여 전송하는 단계(205, 206); 상기 판단결과 경보가 검출되지 않고 디엠에이(DMA)상태이면 디엠에이2 바이패스(DMA2 BYPASS)상태로 셋한 후 링경보비트(RING_ALM_BIT)를 리셋하고 전송하는 단계(212); 상기 판단결과 경보가 검출되지 않고 디엠에이2바이패스(DMA2 BYPASS)상태에서 소정시간이 경과되면 바이패스(BYPASS)상태로 셋하는 단계(210, 211); 상기 판단결과 경보가 검출되지 않고 바이패스(BYPASS)상태로서 모국(주국, Master station)이면, 정기적으로 링경보비트(RING_ALM_BIT)를 리셋하여 전송하고, 모국이 아니면 링경보비트(RING_ALM_BIT)를 그대로 통과시키는 단계(213∼218); 및 상기 링겨보비트(RING_ALM_BIT)에 따라 LED를 점등 혹은 소등시키는 단계(219∼226)가 구비되어 있다. 따라서 모든 노드들은 링 경보 비트에 따라 해당 경보를 표시하므로써 전송로의 장애상태를 표시하여 유지보수를 용이하게 하는 효과가 있다.The present invention relates to a ring alarm method in an ADM network of a synchronous optical transmission apparatus, wherein nodes connected to the network initialize (200 - 203); Reading (204) each F1 byte belonging to the interval overhead of the synchronous multiplexed frame; Checking (205) the F1 byte to determine an alert; If it is determined that an alarm is detected, setting (205, 206) a DMA (DMA) state and setting and transmitting a ring alert bit (RING_ALM_BIT); If it is determined that the alarm is not detected and the DMA is in the DMA state, resetting and transmitting the ring alert bit (RING_ALM_BIT) after setting the DMA2 bypass state (212); (210, 211) when the alarm is not detected and the DMA_BYPASS state is set to a bypass state when a predetermined time has elapsed; As a result of the determination, if the alarm is not detected and the BYPASS state is the master station, the ring alarm bit RING_ALM_BIT is periodically reset and transmitted. Otherwise, the ring alarm bit RING_ALM_BIT is passed as it is (213-218); And steps 219 to 226 for turning on or off the LED in accordance with the ringing notice bit RING_ALM_BIT. Therefore, all the nodes display the alarm according to the ring alarm bit, thereby displaying the failure state of the transmission path, thereby facilitating the maintenance.
