LIN Mian-feng, LIU Xue-yuan, FANG Lai-fu, et al. Fault management in optical transport network. [J]. (6):16-21(2000) DOI: 10.13756/j.gtxyj.2000.06.004.
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.
