As part of the service, Sprint will help customers who want to define and/or refine their overarching e-commerce and security policies as they apply to their intranet, Internet and extranet strategies. Once these policies are defined, Sprint can then design and implement the hardware and software solution required for meeting customers' needs.

In addition, Sprint will be offering industry-first guaranteed service levels against packet loss and delay variation with secure, Web-based tools to track the performance of their Global Internet VPN service and Sprint's adherence to its service level guarantees by 1Q00.
