Introduction to Telecommunications opens the doors to the world of telecom by presenting the first layer of the Open Standards Interconnection (OSI) model for communication networks—the physical layer. The program provides an historical perspective on communications technology, from smoke signals to the latest wireless devices. Students learn the basics and the history of Data, Voice, and Video systems. They go on to build their own working telegraph keys, construct the cables to connect them, and send messages to each other.

Students apply their knowledge by using C-Tech’s Interactive Telecommunications Board (ITB). This innovative teaching aid contains simulated 4-pair data systems, coaxial cable systems, and a fiber optic system all in one compact unit. They use electronic testing equipment to:

• Test a 4-pair UTP system
• Test a coaxial system
• Perform a “Tone and Trace” on a copper cabling system
• Perform an optical continuity test on a Fiber Optic cabling system
• Troubleshoot a malfunctioning system

Technology Learning Activities throughout the text provide opportunities for the students to couple their knowledge with creativity in solving communications problems drawn from real-world scenarios.

Throughout the program, problem-solving and analysis are emphasized, and the ability to relate abstract representations to the concrete realities they depict.

Students who successfully complete this program receive a certificate of completion. The program is also available in Spanish.
