| This study will contain a textual description of each world class ATM/IP/Gigabit Ethernet switch systems in a standard format, as well as a 9-page highly formatted technical specification section describing each system.
In addition, the report will provide an analysis on the installed-base and on-order position of switching systems by country and leading reference customer, as well as a summary of the switching systems installed or on-order for each manufacturer, again broken out by country. The report will draw conclusions concerning the overall status of this technology in Public Networks (and ISP Operators) throughout the world, as well as the relative market position of each of the major switching suppliers.
