Description

SDH training course description

Our SDH training course is designed for those with a basic knowledge of the principles of telecommunication digital transmission techniques. An overview of the existing transmission hierarchies and their limitations is provided with an introduction to the Synchronous Digital Hierarchy (SDH). The advantages of SDH are explained fully.

What will you learn

• Identify the major limitations of the PDH network.
• Outline the advantages of using the SDH.
• Illustrate the various SDH equipment and network topologies.
• Describe the principles of the SDH multiplexing structure.
