For many broadband cable operators DOCSIS has supplanted pay TV as their most popular and profitable service offering. To support the growth of this product all customer contact employees should have a thorough understanding of the DOCSIS product. The Discovering DOCSIS-Customer Premises mini-course is targeted to field and customer care center employees that install, service and support DOCSIS products inside the customer premises. Comprised of three lessons, the course details the evolution of DOCSIS beginning with DOCSIS 1.0 and continuing through DOCSIS 3.1 and explains what goes on in the background when a modem is provisioned for service. Orthogonal frequency division multiplexing (OFDM), the transmission system used in DOCSIS 3.1, is introduced and explained, preparing the student for the next generation of DOCSIS. Lastly, the course instructs the student on preparing the DOCSIS modem for installation, activating the DOCSIS modem in the customer premises and then educating the customer.
