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.

Key outcomes from this course

By the end of the course delegates will be able to:
  • 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.
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.
2 days

Training approach

This structured training course seeks to build upon workbook learning through the use of group exercises, dynamic discussion and individual tasks in order to deliver an engaging and interactive module that will ensure all candidates are able to transfer their new skills into the workplace.

Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
