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.
