Lesson 5/PT = 0x21/8 ODU0 – Mapping/Multiplexing 8 ODU0 Tributary Signals into an ODU2 Server Signal

This blog post presents a video that (1) Introduces the Viewer to the PT = 0x21 Approach to Mapping/Multiplexing Lower-Speed ODUj Tributary Signals into an ODUk Server Signal. This video also describes how we map/multiplex as many as 8 ODU0 Tributary Signals into ODU2 Server Signal.

Introduction to PT = 0x21 and Mapping/Multiplexing 8 ODU0 Tributary Signals into an ODU2 Server Signal (PT = 0x21)

This blog post includes a video that:

  • Introduces the viewer to the PT = 0x21 Scheme for Mapping/Multiplexing Lower-Speed ODUj Tributary Signals into an ODUk Server Signal, and
  • Shows how we map and multiplex as many as 8 ODU0 Tributary Signals into an ODU2 Server Signal, using the PT = 0x21 Approach.

In this video, we discuss the following:

  • Using the GMP (Generic Mapping Procedure) to map each ODU0 tributary signal into their respective ODTU2.1 signal/frames.
  • How to combine these ODTU2.1 signals together and map them into an ODU2 payload.
  • Transporting these GMP Justification parameters from the Source PTE (where we map/multiplex these ODU0 tributary signals into an ODU2 server signal) to the Sink PTE (where we de-multiplex and de-map out the ODU0 tributary signals).
  • A review of the Multiplex Structure Identifier within this type of ODU2 signal.
