Understanding Modern Cable Systems using DOCSIS

Course Description

The next generation of telecommunications networks will deliver broadband data and multimedia services to users. Integration of Internet Access with TV, music and radio distribution will become a reality provided mechanisms to provide multicast delivery are implemented. IP Television will provide an alternative mechanism for delivering services.

DOCSIS (Data Over Cable Service Interface Specifications) is a set of standards produced by the Cable Television industry for delivering Internet access and other data services over traditional cable television Networks. It has evolved from version 1 through version 2 into version 3 which is able to produce bonded services to customers at speeds in excess of 100 Mbits. Versions exist for North American and European markets separately.

This course provides an understanding of how modern installed Cable systems work today, how they have evolved from analogue into digital services using DOCSIS and Euro-DOCSIS 1.02.0 , then discus how they will continue to evolve into DOCSIS 3.0 services. It will further identify the motivations and mechanisms that will be used to allow new cable systems to support voice, IPTV, Video on demand and provide IMS services for convergence with new 3G mobile networks.

Students Will Learn

Describe The Basic Structure Of DOCSIS And Euro-DOCSIS Standards
Select The Appropriate Parts Of The DOCSIS Specifications
Implement The Required Services At The Customer And Network Sides
Provide Baseline Privacy Plus Service
Select Appropriate IP Service Mechanisms For Address Allocation
Carry Internet Services Over Cable Network Infrastructures

Prerequisites

Students should have a solid understanding of IP.

Equipment Requirements
(This apply's to our hands-on courses only)

BTS always provides equipment to have a very successful Hands-On course. BTS also encourages all attendees to bring their own equipment to the course. This will provide attendees the opportunity to incorporate their own gear into the labs and gain valuable training using their specific equipment.
