Let’s Get StartedLet’s Get Started Why WAS Cable TV Different than Telecom?
• Telecom – 1876 – 127 years old• Telecom – Union schools & Apprenticeships• Telecom – Early standards body – Bell Labs• CATV – On-the-Job Training [OJT]• CATV – Vendor control of technology• CATV – Training isn’t always rewarded• CATV – Loss of Monopoly

Learning ObjectivesLearning Objectives
By the end of this webinar, learners will be able to:
• Define the term “best practice”• List new tools and techniques to use in the Data/Cable TV installation process• Explain how the use of best practices and training can measurably benefit an organization
