The Troubleshooting Advanced Services course builds on the knowledge acquired in the Broadband Digital Installer course and complements it with a focus on troubleshooting. The three main service areas of a cable operator are covered in the Troubleshooting Advanced Services course: digital video, data/Wi-Fi and voice. The course is geared to troubleshoot at the customer premises and teaches real world processes that the student can use in a real work environment. Scenarios are presented for addressing specific issues of triple-play services at the premises, as well as the philosophy, mindset and attitude of a successful troubleshooter that can be applied to any circumstance.
