SDH foundation  |    A 2 day training course

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.
SDH training course details
  • Who will benefit:
  • Anyone working with SDH.

  • Prerequisites:
  • It should be noted that this course will assume some basic telecommunication transmission knowledge from the delegates attending. This may be accomplished by attending the Introduction to Telecommunications course.

Based on customer ratings

V. S. - Orange / I-Systems

"Beautiful location with good facilities and friendly staff. There is much more to learn. The SDH course scratches the surface of many more avenues. It was an enjoyable course which gave me the basic knowledge I was expecting."

J. B. - SSE

"I now feel I understand SDH and how it works."

Training approach

This structured course uses Instructor Led Training to provide the best possible learning experience. Small class sizes ensure students benefit from our engaging and interactive style of teaching with delegates encouraged to ask questions throughout the course. Quizzes follow each major section allowing checking of learning.
