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 3N – 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.

This post provides a comprehensive review and video training of the ODU frame and its overhead fields.
Lesson 2 – ODU (Optical Data Unit) Frame Training
This post presents a video that discusses the ODU (Optical Data Unit) Frame in considerable detail.
In addition to discussing the ODU frame format, this video also discusses the ODU overhead fields and their roles.
Finally, this video discusses special ODUk signals, such as ODU0, ODU2e, and ODUflex.
