The NCTI Advanced DOCSIS Operations course is directed to an audience of engineers and headend technicians who have responsibility for configuring and maintaining DOCSIS operations throughout the broadband cable network. The course provides an overview of DOCSIS 3.1 and catalysts for its development before going into detail about orthogonal frequency division multiplexing (OFDM) and how it is applied and configured for DOCSIS 3.1. The course explains key operational DOCSIS parameters that must be configured for operations and then monitored after the product is launched to broadband cable customers. Legacy DOCSIS versions share many of the same configurations with DOCSIS 3.1, which is built on top of the legacy DOCSIS architecture. Thus, this course offers value to students working with DOCSIS versions prior to 3.1 as well. Technicians will even learn about some lesser known features of DOCSIS 3.1, how to enable them and their benefit to the operator and customers.
