OTN – Lesson 11 – Tandem Connection Monitoring – Source Atomic Functions

This blog post presents video training on the Source Direction Tandem Connection Monitoring-related Atomic Functions.

Lesson 11 – Video 2 – Tandem Connection Monitoring – Source Atomic Functions

This blog post contains a video that covers the Source-Direction Tandem Connection Monitoring (TCM) related Atomic Functions.

In particular, this video covers the following Atomic Functions

  • ODUT/ODU_A_So – ODUT to ODU Adaptation Source Function, and 
  • ODUT_TT_So – ODUT Trail Termination Source Function

In each case, we will discuss how these functions generate and handle an ODUT (ODU – Tandem Connection Monitoring) signal.

We will also define terms such as TCM Levels and Modes.
