Lesson 11 – Video 7 – Tandem Connection Monitoring – ODUTm_TT_Sk and ODUT/ODU_A_Sk Atomic Functions
This blog post contains a video that covers the fifth part of the Sink Direction Tandem Connection Monitoring (TCM) related Atomic Functions.
In particular, this video covers the following two atomic functions:
- ODUTm_TT_Sk (Atomic Function for Non-Intrusive Monitoring – TCM Applications), and
- ODUT/ODU_A_Sk
More specifically, this video covers the following aspects of each of these Atomic Functions.
- ODUTm_TT_Sk Atomic Function
- Applications in which we would use the ODUTm_TT_Sk Atomic Function (e.g., Non-Intrusive Monitoring for TCM Subnetworks)
- A brief overview of this function’s capabilities and attributes
- How this function differs from the ODUT_TT_Sk Atomic Function?
- When the ODUT_TT_Sk Function is operating in the OPERATIONAL Mode
- If the ODUT_TT_Sk Function is running in the MONITOR Mode, and
- When the ODUT_TT_Sk Function is working in the TRANSPARENT Mode
- ODUT/ODU_A_Sk Atomic Function
- Where this function fits into the Tandem Connection Monitoring Network
- The Architecture/Functionality of the ODUT/ODU_A_Sk Function
- Operation in the various TCM Modes (e.g., OPERATIONAL and MONITOR/TRANSPARENT).
- The Protection Port (for Automatic Protection Switching support).
- The Removal Block – How this function terminates the “Selected TCMOH and APS/PCC field.”
- Replacing the Normal ODU signal (carrying client data) with either the ODU-AIS or ODU-LCK Maintenance Signals.
- Asserting CI_SSF and CI_SSD in response to upstream defect conditions.
This video completes our discussion/review of the TCM-related Atomic Functions.
