OTN – Lesson 12 – Detailed Discussion of CL-SNCG/I Monitoring (Protection Switching)

This blog post presents a video that describes (in detail) CL-SNCG/I (Compound Links – Subnetwork Circuit Group – Inherent) Monitoring for Protection Switching.

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.
