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.

Following are the strongly recommended prerequisites for this cable training course: 

  • Students should have knowledge and experience with the Cisco IOS Command Line Interface (CLI)


Target Audience:

This course is designed for technical professionals who need to know how to deploy CMTS platforms and associated equipment.


The primary audience for this course includes:

  • Cable Operator Network Operation Center personnel
  • System Engineer/ Integrator/ Solutions support personnel
  • Channel partners, resellers


Course Objectives:

After completing this course, the student should be able to:

  • Describe RF Networking Concepts when applied to the MSO environment
  • Explain and observe DOCSIS modem registration
  • Describe the components that comprise the DOCSIS 3.1 specification set and explain the primary elements in functional block-diagram form
  • Describe DOCSIS 3.1 functionality as it relates to:
    • Comparison to DOCSIS 3.0 channel bonding strategies
    • High bandwidth support for advanced (multimedia, IP-based) services
    • Deployment considerations for modular and integrated CMTS
  • Relate channel bonding terms and acronyms to available downstream channel bonding hardware and Cisco cBR-8 software releases
  • Identify Cisco cBR-8 features and featurettes for best system performance in mixed DOCSIS 1.x/2.0/3.0 and DOCSIS 3.1 channel-bonded environments
  • Identify necessary third-party DOCSIS 3.1 components, such as the Symmetricon DTI server, and gain the knowledge necessary to recognize the role of any third-party components in a customer’s design
