OTN – Lesson 10 – Handling Defects at the ODU-Layer – Defect Scenario Video

In this video, we presume that some ODUk- (or OTUk-) Layer circuitry is declaring a certain defect condition. We then determine how ODU-layer circuitry is expected to respond.

OTN – Lesson 10 – Handling Defects at the ODU-Layer – Defect Scenario for Multiplexed and Non-Multiplexed Applications

This video summarizes each of the various defects that OTN circuitry can declare/clear at the ODU-Layer.  

This video also describes how ODU-Layer circuitry is expected to respond to each of these ODU-Layer (or upstream OTU-Layer) defects.  

  • Should it transmit PM-BDI (Path Monitoring – Backward Defect Indicator) upstream?
  • Should it replace the under-lying 100oBASE-X or 100GBASE-R client signal with either the Link or Local Fault Indicator?  

NOTE:  This video covers both Non-Multiplexed and Multiplexed Applications.

OTN – Lesson 10 – Video 6M – End of ODU-Layer/Multiplexed Sink Circuitry

This post presents the 6th 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 6 – The ODU0_TT_Sk and ODUkP/CBR_ETC1000X_A_Sk Atomic Functions

This blog post contains a video that wraps up our discussion of the Sink (or Receive) Atomic Function circuitry for the ODU-Layer/Multiplexed Applications.  

More specifically, this video includes a discussion of the following Atomic Functions.

  • ODU0_TT_Sk Function, and
  • ODU0P/CBR_1000X-g_A_Sk Function

OTN – Lesson 10 – Video 3N – The OTUk/ODUk_A_Sk and ODUk_TT_Sk Atomic Functions

This post presents the 3rd 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.

OTN – Lesson 10 – Video 3 – The OTUk/ODUk_A_Sk and ODUk_TT_Sk Atomic Functions

This post contains a video that begins our discussion of the Receive (or Sink) Direction circuitry.  

In particular, this video covers the following Atomic Functions.

  • The OTUk/ODUk_A_Sk Atomic Function, and
  • A portion of the ODUk_TT_Sk Atomic Function.

This video covers the following features associated with the ODUk_TT_Sk Atomic Function.

  • Checking for Near-End Errors (e.g., PM-BIP-8 Errors)
  • Checking for Far-End Error Counts (e.g., PM-BEI)

This video also discusses how the ODUk_TT_Sk function will declare and clear the PM-dBDI (Backward Defect Indicator) defect condition.
