COM 201: Multiplexing and TDM Communications


This course is designed for utility engineers and technicians who specify, design, operate, or maintain utility networks, including utility protection engineers, automation engineers, integration engineers, and novice communications engineers and managers.

Dependable communications for critical infrastructure are crucial when you are deploying fiber networks. Time-Division Multiplexing (TDM) offers proven and reliable time-deterministic channels for mission-critical data, such as protection and control. TDM multiplexers can be deployed anywhere and are ideal for private networks where you have complete control to engineer each application for optimal performance.

In this SONET and multiplexing fundamentals course, you will learn about the concepts and considerations that are involved in designing a SONET-based network. This course will prepare you to implement multiplexer network applications, and during this one-day course, you will design a realistic multinode SONET-based OC-48 network. It will also provide a concise introduction to the concepts that will be applied in APP ICON.
