This platform provides both DSL aggregation and managed IP services for carriers and providers. Nortel got the Shasta 5000 BSN out to market early, resulting in top ranking for units shipped and worldwide revenue in Infonetics' 1Q00 report. We've signed 30 customers to date, and implemented around 15 of those. The biggest of these is Bridge Information Systems, which we're migrating away from our private network. According to Hokamp, combining the Shasta 5000 BSN with its ATM backbone lets Savvis to deliver the best of both worlds.
Private networks are very secure and offer controlled performance.
Private ATM and Frame Relay networks have been popular for years, but they can be complex, requiring CPE routers and interconnection of all sites with fully-meshed PVCs. In the last few years, we've also seen CPE-based VPNs. But you still have to deploy a CPE device with IPsec and firewall capabilities, and you lose control over performance. Savvis is also finding it easier to manage network-based services. We're simplifying the network on our side, because the Shasta 5000 BSN is easier to implement and manage than CPE, and network-based VPNs are easier to design.
