Overview

This seminar covers all aspects of ATM technology concerned with building an ATM network in either a service provider of private backbone environment to function as a multi-service platform. It explores the objectives and mechanisms of ATM, especially its ability to provide quality of service and describes how these are used to carry voice data and video applications. A high quality workbook that contains fully documented text as well as a copy of all the slides accompanies the course. The intention is that the workbook should provide a useful reference volume for delegates long after they have attended the course.

Prerequisites

This course assumes that delegates have had previous exposure to data networks and understand the basic principles of data communications. Delegates should ideally have some Hands On experience in a support environment, although this is not strictly required.
