Lesson 12 – Video 5 – Detailed Discussion of CL-SNCG/I (Compound Links – Subnetwork Circuit Group – Inherent) Monitoring for Protection Switching
This blog post contains a video that presents a detailed discussion of CL-SNCG/I Monitoring ], for Protection Switching purposes, at the ODU layer.
In particular, this video will discuss the following topics:
- A Quick Review of the SNC/I Monitoring at the ODU Layer
- A Single ODUj Tributary is the Normal Traffic Signal
- How CI_SSF and CI_SSD initiate Protection Switching
- How to perform CL-SNCG/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 CL-SNCG/I Monitoring at the ODU Layer?
- What happens when we declare an ODUk Server-Layer service-affecting defects (such as dAIS, dOCI, dLCK, dTIM).
- What happens when we declare the PM-dDEG (ODU-Layer Signal Degrade) defect?
- How does protection-switching work?
- How is CL-SNCG/I Monitoring (for Protection-Switching) different from SNC/I Monitoring for Protection-Switching.
- PI-TSF/PI-TSD versus CI_SSF[n]/CI_SSD[n]
- Multiple ODUj Tributary Signals are the Normal Traffic Signal
- dPLM, dLOOMFI, dMSIM[n], and dLOFLOM[n] do not cause Protection-Switching when CL-SNCG/I Monitoring.
