SCOPE OF THE REPORT
Project ESS Update 40 consists of two volumes, each of which stands as an independent report, but with key relationships between them. The common thread is that of PSTN switching.
Volume One of this report focuses upon Next Generation switching systems for public networks. Volume Two provides a detailed analysis of worldwide digital switching system status by manufacturer, country and operator. This constitutes the most comprehensive database on digital switching technology deployment available anywhere in the world.

This report provides executives of both telecom service providers and telecom equipment vendors with guidance useful for budgetary planning, technology selection, equipment selection, and precautions to be taken in planning the implementation of new technology products in the field of Next Generation convergent multi-service switching systems. It provides the following major categories of information and guidance:

• Next Generation technology trend analysis and capability forecasts
• Cost-based price forecasts for both local and tandem packet exchanges
• Evaluation of alternative architectures for both Next Generation switches and networks
• Systems descriptions (both text and formatted specifications) of all world-class Next Generation converged multi-service switching systems (30) offered on the world market, that have general availability within the next nine months
• Case studies of 14 pioneering telecom service providers implementation experience with such systems
• A rough market forecast for such systems
• Conclusions and recommendations for each type of telecom service provider
