DOCSIS® 3.1 Installation Seminar

Course Description

DOCSIS® 3.1 Installation Seminar is designed for broadband installation professionals who need to improve their understanding of the elements and implementations of the DOCSIS® 3.1 specifications, as well as the differences and uniqueness from previous versions of DOCSIS®.

The course defines the industry drivers for DOCSIS® 3.1, modifications in the RF spectrum, feature enhancements, capacity improvements and details on modifications to the physical and media access control (MAC) layers. The course also allows installers to understand the operational implications, procedures for installation and methods used for troubleshooting DOCSIS® 3.1.

For field engineers and techs, communications technology is getting ever more complicated to work with. However, in the end there is still only a 45-minute window given to complete the job. For a modern field technician, it is imperative to understand how modern communications networks operate, to keep up with technological advances and to incorporate them into the daily job on the network.

AXP DOCSIS® training seminars are designed to deliver precisely this knowledge.

  • DOCSIS® training seminars can be modified to the customer’s specific needs.
  • Custom modules designable
  • Onsite- and online presentation, including practical
  • Presentation in English or German

Target Audience:

This course is recommended for both independent cable and multi-system operator (MSO) technical professionals, including mid- to senior- level data engineers and technicians; maintenance and installation technicians; and technical operation (TechOp) managers.
