DOCSIS - Implementing Cisco Data Over Cable Service Interface Specification 3.1 (DOCSIS)

This Data Over Cable Service Interface Specification (DOCSIS), Instructor-Led course covers key standards and concepts from DOCSIS 1.x through to 3.1. It provides hands-on DOCSIS experience and establishes important foundational knowledge needed for configuring bi-directional channel bonded services and other advanced-service features. While examples of implementing DOCSIS services on the Cisco cBR-8 may be used in this course, most of the learning experiences also apply to other CMTS platforms. The course includes lab activities and/or demonstrations to reinforce the key learning objectives.
