DOCSIS®3.1 Essentials

Description:

DOCSIS® 3.1 Essentials prepares broadband professionals with a better understanding of the elements and implementations of DOCSIS 3.1 in the cable network as well as the differences and uniqueness from previous versions of DOCSIS. This course provides an overview of the vast changes that DOCSIS 3.1 offers, goes into details on modifications to the physical (PHY) and media access control (MAC) layers and discusses the operational implications of deploying it.


Target Audience:

This course is recommended for both independent cable and MSO technical professionals, including mid- to senior- level data technicians; maintenance and headend technicians; and engineering managers and executives.


Recommended Prerequisites:

  • SCTE·ISBE Understanding DOCSIS Technology

 

Course Objectives:

Upon successful completion of this course the student will be able to:

  • Describe what DOCSIS 3.1 is and how it works
  • Discuss the differences from previous versions of DOCSIS
  • Understand the characteristics in signal processing, capacity, configurations in the upstream and the downstream.
  • Identify the PHY and MAC Layer modifications
  • Become familiar with the operations of DOCSIS 3.1
