OTN – Lesson 10 – Video 4M – ODUkP/ODUj-21_A_Sk Atomic Function

This post presents the 4th 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 4M – Continuation with the ODUkP/ODUj-21_A_Sk Atomic Function

This blog post contains a video that continues our discussion of the ODUkP/ODUj-21_A_Sk Atomic Function.  Further, this video picks up (where we left off in Video 3M) where we were discussing the need to maintain synchronization with the OMFI byte-field, and

It proceeds to describe how the ODUkP/ODUj-21_A_Sk declares and clears the dLOOMFI defect condition as we walk through the dLOOMFI/In-Multi-Frame State Machine Diagram.

OTN – Lesson 10 – Video 3M – ODUkP/ODUj-21_A_Sk Function

This post presents the 3rd 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 3M – The ODUkP/ODUj-21_A_Sk (The ODUk to ODUj Multiplex Sink) Atomic Function

This page contains a video that discusses the ODUkP/ODUj-21_A_Sk Atomic Function in detail.  

The purpose of this Atomic Function is to accept an ODUkP server signal and de-multiplex and de-map out each of the various lower-speed ODUj tributary signals within this ODUkP server signal.  

This atomic function will also check for each of the following defects within the ODUkP Server and ODUj Tributary Signals:

  • ODUkP Server Level
    • Service-Affecting Defects
      • dLOOMFI
      • dPLM
  • ODUj Tributary Level
    • Service-Affecting Defects
      • dLOFLOM[p]
      • dMSIM[p]

We will cover how the ODUkP/ODUj-21_A_Sk function declares and clears these defects.  And More….

Lesson 5 – PT = 0x21 Approach/ODU4 – Mapping/Multiplexing Lower-Speed ODUj Tributary Signals into an ODU4 Server Signal

This blog post provides an introduction to the PT = 0x21 Approach for Mapping/Multiplexing Lower-Speed ODUj Tributary Signals into an ODUk Server Signal. It also discusses the General Rules for Mapping/Multiplexing Lower-Speed ODUj Tributary Signals into an ODU4 Server Signal.

Lesson 5 – General Rules for Mapping/Multiplexing Lower-Speed ODUj Tributary Signals into an ODU4 Server Signal

Whenever you wish to map/multiplex Lower-Speed ODUj Tributary signals into an ODU4 Server Signal, things are a bit different from that if you were to map/multiplex these tributary signals into an ODU1, ODU2, or ODU3 server signal.  

For example, whenever we map/multiplex lower-speed ODUj tributary signals into an ODU4 server signal, we ALWAYS use GMP (Generic Mapping Procedure).  

This page includes a video that discusses the basic RULES for Mapping/Multiplexing Lower-Speed ODUj Tributary Signals into an OPU4/ODU4 Server Signal.  

Afterward, I present links to many videos that permit you to review the specific mapping/multiplexing cases you wish to learn about.   I list links to the following videos.

  • Mapping as Many as 80 ODU0 tributary signals into an ODU4 Server Signal
  • Mapping as Many as 40 ODU1 tributary signals  into an ODU4 Server Signal
  • Mapping as Many as 10 ODU2 or ODU2e tributary signals into an ODU4 Server Signal
  • Mapping as Many as 2 ODU3 tributary signals into ODU4 Server Signal
  • Mapping Some Number of ODUflex signals into an ODU4 Server Signal
  • A Summary of Everything We’ve Learned about Mapping/Multiplexing ODUj Tributaries into an ODU4 Server Signal.
