This self-paced, online course presents common ways theft of service can occur in a CATV network such as modem cloning or reuse of a valid modem configuration file. The course examines how E6000 CER features can be configured to prevent these and other types of service threats in the cable network. This course is based exclusively on DOCSIS issues.
