Course Objectives

This course offers an in-depth introduction to two major transmission solutions which dominate on the global telecommunication market. It presents earlier concepts such as PCM and PDH, and then follows with a short introduction of physical media (optic fibres), and continues with a thorough overview of SDH/SONET. The main aim of the course is present both generic as well as detailed aspects of using both solutions in transportation of various types of traffic such as voice and data.

Pre-requisites

Participants are expected to have general understanding of generic telecommunication terms. Telecommunication or IT related background will be an advantage.

Training Structure

Three days training divided into logical sessions.

Methodology

Instructor led training.
