DOCSIS 3.1 is the latest version of the DOCSIS set of specifications, promising download speeds of up to 10 Gbps. It defines a totally new physical layer for achieving those speeds. However, to fully utilize its features, major HFC network upgrades are required, and the operational side shows quite some differences.

This DOCSIS 3.1 training is targeted for people who need a view on DOCSIS 3.1 from the operations point of view. The fundamentals of DOCSIS 3.1 are explained and enriched with 3.1 operational monitoring subjects. This training is especially suited for people having to look at the network performance and help to support technical challenges.

•Achieve an understanding of technological evolution and its advantages along with basic new concepts introduced in DOCSIS 3.1
