There is growing concern that new engineers, planners, and field technicians are not aware of the danger and reliability issues surrounding proper protection of telecommunications circuits. Using a practical, hands-on approach, High Voltage Protection for Telecommunications combines all the essential information and key issues into one book. Designed for professional training and self-study, the text will help guide managers, engineers, planners, and technicians through the process of planning, designing, installing, and maintaining safe and reliable data and voice communications circuits that are exposed to High Voltage events.
