摘要
用分层方法讨论了光传送网络的告警管理功能 ,着重分析了全光网络中缺陷指示信号的起源、传输与终结问题 .此外还对光监控信道的故障情况的处理方法进行了讨论 .
This paper studies the fault management in optical transport network (OTN) using the layering concept,with focus on the defect indication signal, including its source, transmission and termination. The optical supervisory channel (OSC) is so important that we think it should be taken as one independent sub-layer of the all-optical transport network (OTN) and discussed in this paper.
