OTN – Lesson 11 – Tandem Connection Monitoring Multi-Administrative Domain Defect Analysis – Part TWO

This blog post contains the second of two videos that analyzes how the Multi-Administrative Domain uses Tandem Connection Monitoring to respond to service-affecting defects within an ODU signal passing through it.

Lesson 11 – Video 11 – Tandem Connection Monitoring (TCM) Multi-Administrative Domain Defect Analysis – Part TWO

This blog post contains a video covering the second (and final) part of the Multi-Administrative Domain Walk-Through when defects occur.

In particular, this video discusses how the Multi-Administrative Domain will respond to the presence of defects.

This video will analyze the Multi-Administrative Domain’s response to the following two cases.

Case 2 – Whenever a Service-Affecting defect occurs within Serving Operator Domain – Operator B, and

Case 3 – Whenever a Service-Affecting defect occurs within the Protect Domain.

NOTE: In the previous video, we analyzed Case 1 (Service-Affecting defect occurs within the ODU signal but outside of any of the administrative regions).

As we analyze the Multi-Administrative Domain’s response to these defects (for Cases 2 and 3), we will cover the following topics:

  • What exactly occurs within an ODU signal that experiences a service-affecting defect?
  • How do ODU-layer, ODUT-layer, and OTU-layer circuitry respond to such defects?
  • How does the circuitry within these Administrative Domains respond to the service-affecting defects associated with Cases 2 and 3?
  • What does the Path Terminating Equipment (at the remote terminal) do in response to these service-affecting defects?

This video will close out our discussion of Lesson 11 – Tandem Connection Monitoring.

OTN – Lesson 11 – Tandem Connection Monitoring Multi-Administrative Domain Defect Analysis – Part ONE

This blog post contains the first of two videos that analyzes how the Multi-Administrative Domain uses Tandem Connection Monitoring to respond to service-affecting defects within the ODU signal passing through it.

Lesson 11 – Video 10 – TCM Multi-Administrative Domain Defect Analysis – Part ONE

This blog post contains a video covering the first part of the Multi-Administrative Domain Walk-Through when defects occur.

In particular, this video discusses how the Multi-Administrative Domain will respond to the presence of defects.

During this video, we assume that we are experiencing a service-affecting defect within the ODU signal (that passes through the Multi-Administrative Domain). However, in this case, we assume that the defect occurs outside any administrative regions. As we analyze the Multi-Administrative Domain’s response to this defect, we will cover the following topics:

  • What exactly occurs within an ODU signal that experiences a service-affecting defect?
  • How do ODU-layer, ODUT-layer, and OTU-layer circuitry respond to such defects?
  • How does each Administrative Domain respond to the presence of a service-affect defect outside of the Service-Requesting (or any other Domain) using Tandem Connection Monitoring?
  • What does the Path Terminating Equipment (at the remote terminal) do in response to this service-affecting defect?

I hope the student will better understand Tandem Connection Monitoring as we go through this and the following video.
