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.
