Operations Center Technical Support II provides key technical skills and knowledge that allow network operations center personnel to quickly identify customer and network issues, perform troubleshooting to isolate the issue and direct the fix. This course specifically focuses on the reliability of the entire broadband network. Its coverage of electronic circuit theory provides a foundation for understanding decibels (dB), decibel millivolts (dBmV), signal leakage detection and troubleshooting techniques. The course’s basic mathematics review prepares the broadband professional to tackle equations and formulas relating to basic electronic theory and signal level calculations. The course also addresses networking technologies, such as wired and wireless LAN’s (local area networks), WAN’s (wide area networks), as well as how antennas work. An understanding of these networking technologies is critical for network operations personnel in the networked world where we live and work. The course concludes with basic characteristics and functions of line extender amplifiers used in the distribution portion of the network.
