This blog post includes a video that serves as the 3rd (of our 4 Videos) that discusses the ODUT_TT_Sk Atomic Function. This video focuses on the TCMi-dDEG (Signal Degrade) defect condition, Defect Correlation and Consequent Equations.

Lesson 11 – Video 5 – Tandem Connection Monitoring – ODUT_TT_Sk Atomic Function, Part THREE

This blog post contains a video that covers the third part of the Sink Direction Tandem Connection Monitoring (TCM) related Atomic Functions.

In particular, this video covers the third part of the ODUT_TT_Sk Atomic Function.

More specifically, this video covers the following operations (within the ODUT_TT_Sk Atomic Function).

  • How the ODUT_TT_Sk Atomic Function declares and clears the TCMi-dDEG (Signal Degrade) defect condition
  • Defect Correlation within the ODUT_TT_Sk Atomic Function. This video reviews the following Defect Correlation Equations:
    • cSSF <- CI_SSF or dAIS;
    • cLTC <- dLTC and (NOT CI_SSF);
    • cOCI <- dOCI and (NOT CI_SSF);
    • cLCK <- dLCK and (NOT CI_SSF);
    • cTIM <- dTIM and (NOT CI_SSF) and (NOT dAIS) and (NOT dLTC) and (NOT dOCI) and (NOT dLCK);
    • cDEG <- dDEG and (NOT CI_SSF) and (NOT dAIS) and (NOT dLTC) and (NOT dOCI) and (NOT dLCK) and (NOT(dTIM and (NOT TIMActDis)));
    • cBDI <- dBDI and (NOT CI_SSF) and (NOT dAIS) and (NOT dLTC) and (NOT dOCI) and (NOT dLCK) and (NOT dTIM) and (NOT TIMActDis)));
  • Consequent Equations within the ODUT_TT_Sk Atomic Function. This video review the following Consequent Equations:
    • aBDI <- (CI_SSF or dAIS or dLTC or dOCI or dLCK or dTIM) and TCMCI_Mode != TRANSPARENT;
    • aBIAE <- dIAE and TCMCI_Mode != TRANSPARENT;
    • aTSF <- CI_SSF or ((dAIS or (dLTC and LTCAct_Enable) or dOCI or dLCK or (dTIM and (NOT TIMActDis))) and TCMCI_Mode == OPERATIONAL;
    • aTSD <- dDEG and TCMCI_Mode == OPERATIONAL;
    • aAIS <- (dOCI or (dLTC and LTCAct_Enable) or dLCK or (dTIM and (NOT TIMActDis))) and TCMCI_Mode == OPERATIONAL;
    • aBEI <- nBIPV and TCMCI_Mode != TRANSPARENT;

OTN – Lesson 10 – Video 5M – Conclusion of the ODUkP/ODUj-21_A_Sk Function

This post presents the 5th of the 6 Videos that covers training on the Peformance Monitoring of the ODUk Layer (for Multiplexed Applications). This post focuses on the Sink Direction ODU-Layer Atomic Functions.

OTN – Lesson 10 – Video 5M – Conclusion of the ODUkP/ODUj-21_A_Sk Atomic Function

This blog post includes a video that continues our discussion of the ODUkP/ODUj-21_A_Sk Atomic Function.  

In this case, we will now start talking about defects that this function declares within the Lower-Speed ODUj Tributary Signals, that it demultiplexes and demaps from the incoming ODUk Server Signal.

These defects include:

  • dMSIM[p] – Multiplex Structure Identifier Mismatch – for each ODUj Tributary Port signal, p, and
  • dLOFLOM[p] – Loss of Frame, Loss of Multi-Frame Defect (again) for each ODUj Tributary Port signal, p.  

NOTE:  We describe how the ODUkP/ODUj-21_A_Sk function declares and clears the dLOFLOM defect condition, as we walk through the dLOFLOM/In-Frame State Machine Diagram.  

Afterward, we discuss:

  • Defect Correlation Equations and Analyis, and
  • Consequent Equation Analysis

Finally, we wrap up and summarize the ODUkP/ODUj-21_A_Sk Function.
