Introduction to PT = 0x21 and Mapping/Multiplexing 32 ODU0 Tributary Signals into an ODU3 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

In this video, we discuss the following:

Using the GMP (Generic Mapping Procedure) to map each ODU0 tributary signal into their respective ODTU3.1 signal/frames
How to combine these ODTU3.1 signals and map them into an ODU3 payload
Transporting these GMP Justification parameters from the Source PTE (where we map/multiplex these ODU0 tributary signals into an ODU3 server signal) to the Sink PTE (where we de-multiplex and de-map out the ODU0 tributary signals)

OTN – Lesson 6 – Converting OTL3.4 Back into OTU3 – Video 2

This blog post contains a video that serves as the 2nd of two videos that describe the functionality of the OTL3.4 Sink Terminal (aka the OTSiG/OTUk_A_Sk Atomic Function). This video focuses on Skew Compensation and ultimately combining the 4 OTL3.4 Lanes back into a Composite OTU3 signal.

OTN – Lesson 6 – Converting OTL3.4 Signals back into a Composite OTU3 Signal – Video 2 of 2

This blog post contains the second (of 2) videos that describes how we take an OTL3.4 Interface (or set of signals) and convert these signals back into a single (composite) OTU3 signal.

This particular video completes the discussion of the OTSiG/OTUk_A_Sk Atomic Function (which, again, is a fancy word for OTL3.4 Sink Terminal).

NOTE: We formally introduce the OTSiG/OTUk_A_Sk Atomic Function in Lesson 9.

This video discusses how the Lane Marker and Delay Processing Block (within the OTSiG/OTUk_A_Sk Function) evaluates all of the data and metrics coming from the four Lane Frame Alignment, Lane Alignment Recovery, and Elastic Store blocks and:

Measures and performs Skew Compensation,
Declares the dLOL (Loss of Lane Alignment) Defect Condition and
Routes the de-skewed data to the 16-Byte Block MUX – which combines each of the four OTL3.4 lane signals back into a composite OTU3 signal.

OTN – Lesson 6 – Converting OTL3.4 Back into OTU3 – Video 1

This blog post contains a Video that serves as a first (of two) videos that discusses the functionality of the OTL3.4 Sink Terminal (aka OTSiG/OTUk_A_Sk Function). This video focuses on the dLOFLANE and dLOR defects.

OTN – Lesson 6 – Converting OTL3.4 Signals back into a Composite OTU3 Signal – Video 1 of 2

This blog post contains the first (of 2) videos that describe how we take an OTL3.4 Interface (or set of signals) and convert these signals back into a single (composite) OTU3 signal.

This video introduces the OTSiG/OTUk_A_Sk Atomic Function (a fancy word for OTL3.4 Sink Terminal).

NOTE: We don’t mention OTSiG/OTUk_A_Sk Atomic Function until Lesson 9. We call this function the OTL3.4 Sink Terminal.

This video discussed how the OTSiG/OTUk_A_Sk Function accepts electrical lane signals from an Optical Module (in the OTL3.4 format) and processes these signals by:

Checking to see if we should declare/clear the dLOS-P (Loss of Signal – Path) Defect condition with these Electrical Lane signals, and
Checking to see if we should declare/clear the dLOFLANE (Loss of Frame – of Logical Lane) defect condition.
Finally, we will discuss how the OTSiG/OTUk_A_Sk function checks each incoming OTL3.4 lane signal to see if it should declare the dLOR (Loss of Recovery) defect condition.

OTN – Lesson 10 – Video 7N – ODUkP/CBR_ETC100GR-g_A_Sk Atomic Function

This video discusses how the ODUkP/CBR_ETC100GR-g_A_Sk (100Gbps Ethernet Adaptation Sink) Atomic Function processes an ODU4 signal that it receives from the upstream ODUk_TT_Sk Function.

In particular, this video discusses how this function terminates the ODU4 overhead, extracts out processes, and terminates the OPU4 overhead before it extracts and processes the 100GBASE-R client signal.

This blog post presents the 3rd (of a set of 3 videos) that discusses how we convert an OTL4.4 Interface (or group of signals) back into a single (composite) OTU4 signal.

In particular, this video discusses the following:

It outlines how the OTSiG/OTUk_A_Sk function declares and clears the dLOR (Loss of Recovery) defect condition, for each of the 20 Logical Lanes, by walking through the Lane Alignment Recovery Block – LOR/OOR/IR State Machine diagram.
This video also discusses Lane-to-Lane Skew Compensation, and
How the OTSiG/OTUk_A_Sk function declares or clears the dLOL defect condition, and
How the OTSiG/OTUk_A_Sk function combines the 20 Logical Lanes back into a single (composite) OTU4 signal.
