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 = 0x21/32 ODU0 – Mapping/Multiplexing 80 ODU0 Tributary Signals into an ODU4 Server Signal

This blog post presents a video that describes how to map/multiplex as many as 80 ODU0 tributary signals into an ODU4 server signal using the PT = 0x21 scheme.

Mapping/Multiplexing 80 ODU0 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 80 ODU0 Tributary Signals into an ODU4 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 ODTU4.1 signal/frames.
  • How to combine these ODTU4.1 signals together and to map them into an ODU4 payload.
  • Transporting these GMP Justification parameters from the Source PTE (where we map/multiplex these ODU0 tributary signals into an ODU4 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 ODU4 signal.

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 4 – 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 3) where we were discussing the need to maintain synchronization with the OMFI byte-field, and

It proceed 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.
