SDH Fundamentals

Course description (english, PDF)

Duration: 3 days

By introducing synchronous digital Hierarchy (SDH) the network capacities in the world of data transfer have been dramatically increased. This digital technology is today the most widespread method for backbone networks and data lines with a high data emergence.

For network operators it is indispensable that their operators, planners and engineers understand the basic principles of SDH networks in order to apply this technology in an ideal way and to manage it effectively.

The aim of this course is to transfer a wide basic knowledge to anyone who works with SDH networks. The course participants will be able to understand, use and maintain SDH networks better.

Target Group / Requirements

Service technicians, NMC employees, planning and support engineers can take great advantage of this high-level training. Basic knowledge of transfer mode system is required in this course.
