Lesson 5/PT = 0x21/2 ODU3 – Mapping/Multiplexing 2 ODU3 Tributary Signals into an ODU4 Signal

This blog post presents a video that describes how to map/multiplex as many as 3 ODU3 tributary signals into an ODU4 server signal, using the PT = 0x21 scheme.

Mapping/Multiplexing 2 ODU3 Tributary Signals into an ODU4 Server Signal (PT = 0x21)

This blog post includes a video that shows how we map and multiplex as many as 2 ODU3 Tributary Signals into an ODU4 Server Signal, using the PT = 0x21 Approach.

This video, we discuss the following:

  • Using the GMP (Generic Mapping Procedure) to map each ODU3 Tributary Signal into their respective ODTU4.31 signal/frames.
  • How to combine these ODTU4.31 signals together and to map them into an ODU4 payload.
  • Transporting these GMP Justification parameters from the Source PTE (where we map/multiplex these ODU3 tributary signals into an ODU4 server signal) to the Sink PTE (where we de-multiplex and de-map out the ODU3 tributary signals).
  • A review of the Multiplex Structure Identifier (MSI) within this type of ODU4 signal.

You can view this video below.
