OTN – Lesson 10 – Video 2M – The OTUk/ODUk_A_Sk and ODUk_TT_Sk Atomic Functions

This post presents the 2nd 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 2M – The OTUk/ODUk_A_Sk and ODUk_TT_Sk Atomic Functions

This blog post includes a video that begins our discussion of the Sink (or Receive) Direction Atomic Function/Circuitry for the ODU-Layer/Multiplexed Applications.  

In particular, this video reviews the following Atomic Functions

  • OTUk/ODUk_A_Sk Function
  • ODUk_TT_Sk Function

NOTE:  Even though we did review these functions back in the Non-Multiplexed portion of Lesson 10 Training; I wanted to review the Consequent Equations for these functions (once again), because these equations do impact the signals that the ODUkP/ODUj-21_A_Sk function (downstream) will “see”.

OTN – Lesson 10 – Video 6N – Round-Trip Path Delay Measurements, pN_Delay

This post presents the 6th of the 7 Videos that covers training on the Peformance Monitoring of the ODUk Layer (for Non-Multiplexed Applications). This post focuses on the Sink Direction ODU-Layer Atomic Functions. More specifically, this post presents a video that describes how we can use the ODUk_TT_So and ODUk_TT_Sk atomic functions to measure the pN_Delay parameter.

OTN – Lesson 10 – Video 6 – pN_Delay Measurements (via the ODUk_TT_Sk and ODUk_TT_So Atomic Functions)

This blog post includes a video that discuss how we perform round-trip path delay measurements, pN_Delay, (using two sets of ODUk_TT_Sk and ODUk_TT_So functions), by manipulating the DMp bit-field, within each ODUk frame.  

This video also closes out our discussion of the ODUk_TT_Sk Atomic Function.

This post presents the 5th of the 7 Videos that covers training on the Peformance Monitoring of the ODUk Layer (for Non-Multiplexed Applications). This post focuses on the Sink Direction ODU-Layer Atomic Functions. More specifically, this post presents a video that discusses how the ODUk_TT_Sk Atomic Function declares and clears the PM-dDEG defect condition.

OTN – Lesson 10 – Video 5 – The ODUk_TT_Sk Atomic Function

This blog post presents a video that continues our discussion of the ODUk_TT_Sk Atomic Function.  

This video covers the following features within the ODUk_TT_Sk Atomic Function.

  • How it declares and clears the dDEG (Path Signal Degrade) defect condition.
  • What the ODUk_TT_Sk function do with its AI_TSF Output pin whenever it declares a Service-Affecting defect condition.
  • What the ODUk_TT_Sk function do with its AI_TSD Output pin whenever it declares the dDEG (Signal Degrade) defect condition.  
  • Defect Correlation Equation Analysis
  • Consequent Equation Analysis 
  • Performance Monitoring Equation Analysis
