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. 

Completion Time:

The estimated completion time for this course is 48 hours. The maximum allotted time is four months from enrollment.

Benefits:

  • use this course to help prepare for SCTE’s Broadband Premises Installer and Broadband Distribution Specialist certifications
  • receive credit toward NCTI Customer Care Master Representative certification
  • receive credit toward NCTI Master Dispatcher certification
  • receive an industry-recognized NCTI certificate of graduation
