Overview

This course provides and understanding of Time Division Multiplexing techniques. It identifies how TDM systems have evolved, It examines the structure of the Plesiochronous Digital Hierarchy (PDH), how services were delivered and how this is carried on Synchronous Digital Hierarchy today. It will identify the framing and signalling overhead elements of each service and examine the key design parameters for services deploying these technologies. It will also look at how these services can now be interfaces and emulated over Next Generation Networks. The course will include workshop exercises in design.

Objectives

When you have completed this course you will be able to:

  • Describe the principles of Time Division Multiplexing

  • Compare the framing and Overhead bytes of PDH and SDH

  • Identify the different rates and Virtual Containers used in SDH

  • Undertake simple design exercise using TDM technologies
