Course Overview
The NCTI Advanced DOCSIS 3.1 Operations course is the premier training program for engineers and headend technicians responsible for configuring, maintaining, and troubleshooting broadband cable networks.
As cable networks evolve, understanding the shift from legacy systems to the new standard is critical. This course moves beyond the basics, offering a deep dive into Orthogonal Frequency Division Multiplexing (OFDM)—the backbone of DOCSIS 3.1 speed and efficiency. Students will master key operational parameters, learn to optimize downstream channels, and ensure seamless backward compatibility with legacy DOCSIS versions.
Who Should Attend:
- Broadband Engineers
- Headend Technicians
- Network Operations Staff looking to upskill in DOCSIS 3.1 architecture.
What You Will Learn
Upon successful completion of this course, students will possess the skills to specific configurations and monitor network health.
Key Learning Outcomes:
- Architecture Mastery: Compare DOCSIS architecture to the OSI reference model and identify the catalysts driving the shift to 3.1.
- Spectrum Optimization: Master the anatomy of downstream channels, including how 3.1 shares frequency spectrum with previous versions.
- Advanced Configuration: Craft downstream/upstream profiles and configure Cable Modem Termination Systems (CMTS) for reliable operations.
- Network Maintenance: Implement Proactive Network Maintenance (PNM) metrics to detect issues before they impact the customer.
- Technical Deep Dives: Explain Fast Fourier Transform (FFT) application to OFDM and utilize Time and Frequency Division Multiplexing.
Certification and Benefits
Earn an Industry-Recognized Credential
Graduates receive the NCTI Certificate of Graduation, validating their expertise in modern broadband operations.
Additional Benefits:
- Flexible Learning: 100% online delivery with up to four months to complete the 20-hour curriculum.
- Legacy Value: Because DOCSIS 3.1 is built on top of legacy architecture, this training improves proficiency with previous DOCSIS versions (1.0 – 3.0) as well.
- Future-Proofing: Learn lesser-known features of DOCSIS 3.1 to prepare your network for future bandwidth demands.
