APN03 Essentials of ATM Ver 0-2 WEB

This course provides the necessary technical knowledge to enable telecommunications staff to assess the need for, design, installation and maintenance of ATM based Networking Solutions. It is assumed that once products are selected, specific product training is provided by the product vendor.

Who Should Attend:

MIS, Telecommunications Management and Professionals involved in extending enterprise network services to local workgroups and departmental LANs; Consultants, Integrators, Carriers and Equipment Manufacturers; Technical Marketing and Sales Professionals and Network/System/Application Engineers.

Objectives:

• Correctly define and position the ATM technology within the Telecommunication field
• Describe and evaluate the ATM protocols and interfaces and the inter-operability issues
• Discuss AAL Services, Connection Modes and Service Classes
• Identify the suitable and the not suitable applications for ATM
• Correctly choose the needed access circuits and equipment types for your network
• Assess the impact of various supported protocols on an ATM based inter-network and make the necessary design decisions to optimise performance
• Address the issues and solutions related to carrying image, voice and video over ATM
• Discuss private ATM networking, LAN Emulation and LAN extensions
• Discuss criteria to make the necessary buying decisions for a successful ATM implementation, Quality of Service, Service Level Agreements and tariffs
• Discuss inter-working with Frame Relay and other Telecommunication Technologies and ATM Network Management
