Proactive Network Maintenance

Description:

The proactive network maintenance (PNM) course prepares broadband professionals to better understand the elements and implementations of the multiple tools and techniques inside of the PNM tool kit.  This course teaches participants what proactivity truly is and how it applies to their everyday jobs.  It also details: different PNM technologies such as pre-equalization and how it addresses plant problems, how it works within DOCSIS® and how it can be used to identify and locate plant problems. In addition, participants will discover how full RF capture and spectrum analysis can be done in DOCSIS modem chips and how it can be used to identify plant impairments across the access network.  Finally, the next generations of PNM tools are reviewed such as techniques to solve for non-linear distortion and the benefits that orthogonal frequency division multiplexing (OFDM) provides within DOCSIS 3.1 from a PNM perspective.

Module 1:  Introduction to Proactive Network Maintenance.


Module 2:  Why Be Proactive?

Introduction

Proactivity in cable telecommunications refers to identifying network issues before the customers complain about service problems and ideally fix any problems before the customer even knows there was a problem.  This module will allow the broadband professional to define the concept of PNM and understand its effects on cable personnel and customer satisfaction as well as workforce tools and training.  Understanding why to be proactive will instill in you the desire to take a pro-active approach to business.


Module Learning Objectives:
 

Upon successful completion of this topic, you will be able to:

  • Define the concept of PNM
  • Understand the role of technicians, engineers, and managers for PNM
  • Explain how PNM improves customer satisfaction
  • Explain how PNM maximizes network capacity
  • Describe how PNM lowers operations cost by reducing truck rolls and can decrease the mean time to repair (MTTR)

 

Module 3:  PNM Technology Introduction 

Introduction

Common plant impairments can be addressed using equalization technology.  Understanding how equalization, pre-equalization, and adaptive equalization works in DOCSIS systems and how PNM uses pre-equalization coefficients will help you to determine the location of plant impairments on the network.

Module Learning Objectives:

Upon successful completion of this topic, you will be able to:

  • List six plant problems addressed by pre-equalization
  • Describe how pre-equalization in DOCSIS works
  • Explain how PNM can be used to identify and locate plant issues

 

Module 4:  Using PNM

Introduction

Reflections from impedance mismatches on coax can be observed with a time domain reflectometer (TDR).  Using the same principles that are used by TDRs, you can use proactive network maintenance technology, which uses the DOCSIS pre-equalization coefficients from DOCSIS devices all over the network, to determine plant impairment locations.

Module Learning Objectives:

Upon successful completion of this topic, you will be able to:

  • Explain how reflections from impedance mismatches on coax can be observed with TDR
  • Determine using PNM how the location of a plant impairment is determined
  • Compute in-channel frequency response (ICFR) for typical applications
  • Identify other impairments using PNM

 

Module 5:  Full RF Capture with PNM

Introduction

Spectrum analysis can be done with full RF spectrum capture and fast Fourier transform (FFT) in modern DOCSIS chips using PNM.  You will be able to identify and repair various plant problems using full RF spectrum captures in PNM.

Module Learning Objectives:

Upon successful completion of this topic, you will be able to:

  • Describe the basics of RF spectrum analysis for cable
  • Explain how spectrum analysis can now be done with full RF spectrum capture and FFTs in modern DOCSIS chips using PNM
  • Identify various plant impairments using full RF spectrum captures in PNM
  • List example uses of full RF spectrum capture in PNM to identify and repair plant problems

 

Module 6:  Next Generation PNM

Introduction

Based on recent work by Tom Williams of CableLabs, in this module learners will describe how to leverage full RF capture in PNM to enable new approaches for detecting nonlinear distortion in cable networks.  In addition, understanding how DOCSIS 3.1 techniques solve for non-linear distortions and the added benefits of orthogonal frequency division multiplexing (OFDM) creates for additional PNM capabilities. Finally, explore the opportunities for operators to better manage and maintain the HFC access network.

Upon successful completion of this topic, you will be able to:

  • Leverage full RF capture to enable new approaches for detecting nonlinear distortion in cable networks
