Lesson 12 – Video 4 – Detailed Discussion of SNC/I (Subnetwork Circuit – Inherent) Monitoring for Protection Switching
This blog post contains a video that presents a detailed discussion of SNC/I Monitoring, both at the OTU and ODU layers.
In particular, this video will discuss the following topics:
- How to perform SNC/I Monitoring at the OTU Layer
- What Circuitry (Atomic Functions) that we should use
- What defects to monitor
- Which is the Normal Traffic Signal when doing SNC/I Monitoring at the OTU Layer.
- What happens when we declare an OTU Layer Service-Affecting defect (dLOS, dLOF, dLOM, dLOL, dLOFLOM, dLOR, dAIS, and dTIM)?
- What happens when we declare the SM-dDEG (OTU-layer Signal Degrade) defect?
- How does protection-switching work?
- How to perform SNC/I Monitoring at the ODU Layer
- What Circuitry (Atomic Functions) that we should use
- What defects to monitor
- Which is the Normal Traffic Signal when doing SNC/I Monitoring at the ODU Layer.
- What happens when we declare an ODUk Server-Layer service-affecting defects (such as dAIS, dOCI, dLCK, dTIM, dLOOMFI, and dPLM)?
- What happens when we declare ODUj Tributary-Layer service-affecting defects (such as dLOFLOM and dMSIM)
- What happens when we declare the PM-dDEG (ODU-layer Signal Degrade) defect?
- How does protection-switching work?
