With flexible, modular design, state-of-the-art multiprocessor RISC architecture, and unsurpassed value, NETBuilder II® routers are the premier choice for connections to large WANs and network backbones. The 800 Mbps backplane and RISC architecture deliver consistently fast throughput across all interface ports. Simple, on-the-fly software configuration and hot-swapping capability let you add or replace WAN and LAN modules while the unit is operating. This high-bandwidth, standards-based router simplifies local and remote internetworking. Its range of compatible chassis, plus the ability to add processing power over time, provide unsurpassed scalability.

• All interface modules run in any NETBuilder II chassis, and are hot-swappable for easy insertion and removal—with no interruption of service to other networks

• Dual RISC processing, custom ASICs, and an 800 Mbps backplane provide high-speed links for wide area and Token Ring, Ethernet, Fast Ethernet, and FDDI networks, and easy growth to ATM

• Robust IBM SNA multiprotocol choices, including DLSw V2 and APPN/HPR, provide full integration of multiprotocol and SNA environments

• The new dual-processor engine plus module ensures fast packet processing and high throughput for predictable WAN performance

• The new NETBuilder II VPN Starter Kit gives you everything you need to begin setting up a cost-saving, Internet-based extranet infrastructure
