ATM

Overview

This course is probably the best intensive, technical course available on this important technology. ATM's ability to carry differing information types on the same network at very high speeds through the use of small, individually addressable cells has ensured its rapid establishment as the major force for the future. The course is designed for all those who wish to acquire a comprehensive understanding of ATM for use in their own environment and is available in one-day overview, two-day standard and three-day in-depth formats.

Potential delegates

The course is designed for network planners, designers, systems analysts, or support staff and engineers who are about to implement ATM in their infrastructure.

Prerequisites

A good understanding of Local and Wide Area Networking, and communication techniques and methods.

Duration

2 days

Course Objectives

By the end of the course delegates will be able to:

 

·          Describe basic ATM concepts

·          Describe the different layers associated with ATM

·          Describe signalling and addressing

·          Describe the ATM switched Architecture

·          Design networks for this environment that makes best use of this technology
