Lesson 5/PT = 0x21/Summary ODUj Tributary Signal Mapping/Multiplexing into an ODU4 Server Signal

This blog post includes a video that summarizes all of our training on Mapping/Multiplexing ODUj Tributary Signals into an ODU4 Server Signal.

Summary/Review – Mapping/Multiplexing ODUj Tributary Signals into an ODU4 Server Signal (PT = 0x21)

This blog post includes a video that summarizes all of our training on Mapping/Multiplexing ODUj Tributary Signals into an ODU4 Server Signal, using the PT = 0x21 Approach.

In particular, we briefly summarize the following topics within this video.

  • A quick review of Mapping/Multiplexing schemes that use GMP (Generic Mapping Procedure)
  • Mapping and Multiplexing as many as 80 ODU0 Tributary Signals into an ODU4 Server Signal.
  • Mapping and Multiplexing as many as 40 ODU1 Tributary Signals into an ODU4 Server Signal
  • Mapping and Multiplexing as many as 10 ODU2 or ODU2e Tributary Signals into an ODU4 Server Signal
  • Mapping and Multiplexing as many as 2 ODU3 Tributary Signals into an ODU4 Server Signal
  • Mapping and Multiplexing some number of ODUflex Tributary Signals into an ODU4 Server Signal
  • A Discussion on why we logically subdivide ODU1, ODU2, ODU2e, ODU3 and ODUflex tributary signals into time-slots (when mapping/multiplexing into a Higher-Speed ODUk Server Signal), but we don’t do that for ODU0 tributary signals.
  • A Review of the MSI (Multiplex Structure Identifier) within the ODU4 Server Signal for each of these Mapping/Multiplexing Schemes.

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

This blog post includes a video that describes how to map/multiplex some number of ODUflex tributary signals into an ODU4 server signal, using the PT = 0x21 Scheme.

Mapping/Multiplexing Some Number of ODUflex Tributary Signals into an ODU4 Server Signal (PT = 0x21)

This blog post includes a video that shows how we map and multiplex some number of ODUflex 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 ODUflex Tributary Signal into their respective ODTU4.ts signal/frames.
  • How to combine these ODTU4.ts signals together and to map them into an ODU4 payload.
  • Transporting these GMP Justification parameters from the SourcePTE (where we map/multiplex these ODUflex tributary signals into an ODU4 server signal) to the Sink PTE (where we de-multiplex and de-map out the ODUflex tributary signals).
  • A review of the Multiplex Structure Identifier (MSI) within this type of ODU4 signal.

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

This blog post presents a video that describes how to map/multiplex some number of ODUflex tributary signals into an ODU2 server signal.

Mapping/Multiplexing Some Number of ODUflex Tributary Signals into an ODU2 Server Signal (PT = 0x21)

This blog post includes a video that shows how we map and multiplex some number of ODUflex Tributary Signals into an ODU2 Server Signal, using the PT = 0x21 Approach.

In particular, we discuss the following topics in this video.

  1. Subdividing the ODUflex signal into n separate 1.25 Gbps time-slots
  2. Using the GMP (Generic Mapping Procedure) to map the ODUflex tributary signal into its respectively ODTU2.ts signal/frames.
  3. How to combine these ODTU2.ts signals together (along with other signals – ODTU2.ts signals with other values for ts) into an ODU2 payload.
  4. Transporting the GMP Justification parameters from the Source PTE (where we map/multiplex these ODUflex tributary signals into an ODU2 server signal) to the Sink PTE (where we de-multiplexing and de-map out the ODUflex tributary signals).
  5. A Review of the Multiplex Structure Identifiers (MSI) within this type of ODU2 server signal.
