Course Overview

The NCTI Understanding Voice and Data Networks course presents the “Grand Unification” of telecommunications. As legacy phone lines merge with high-speed data pipes, technicians must understand both worlds to advance their careers.

This comprehensive curriculum bridges the gap between traditional telephony and modern Voice over IP (VoIP). Students will start with the physical infrastructure (copper/fiber) and the OSI Model, move through the mechanics of TCP/IP and Ethernet, and finally explore the complex architecture of Converged Networks. You will learn how a voice call differs from a data packet, how SIP and H.323 protocols manage multimedia sessions, and how to troubleshoot networks where voice, video, and data share the same lane.

Who Should Attend:

  • Telecom Technicians
  • Network Engineers
  • VoIP Specialists
  • Technicians preparing for SCTE BTCS Certification

What You Will Learn

Upon completion, students will be able to explain the operation of data networks and telephone systems, and troubleshoot the unique challenges of a converged environment.

Core Competencies:

  • Protocol Stacks: Map data flow through the OSI Model and the TCP/IP Suite, including IP addressing, Subnetting, and Routing.
  • Legacy Telephony: Describe the components of the Public Telephone Network (PSTN), including Central Office switching, Trunks, SS7 Signaling, and PBX systems.
  • Network Infrastructure: Identify the purpose of Hubs, Switches, Routers, and VLANs in managing network traffic.
  • Convergence: Explain Packet Telephony concepts, including Quality of Service (QoS), Traffic Shaping, and Prioritization to ensure voice clarity.
  • VoIP Protocols: Compare the H.323 standard for packet multimedia with the Session Initiation Protocol (SIP) used in modern VoIP.
  • Troubleshooting: Apply a step-by-step method to analyze converged network failure points using common network testing tools.

Certification and Benefits

Master the Future of Telecom

This course provides the fundamental knowledge needed to transition from a “Telephone Guy” or “Data Guy” to a true Communications Specialist.

Additional Benefits:

  • SCTE Prep: Excellent preparation for SCTE Broadband Premises Installer (BPI) and Broadband Telecom Center Specialist (BTCS) certifications.
  • Certification Path: Credits apply toward NCTI Telecom Specialist and Senior Master Technician certifications.
  • Industry Recognition: Receive the NCTI Certificate of Graduation.
