Summary and Conclusion
As companies strive to lower the cost of running their network and increase the productivity of
their end users with network applications, more intelligent branch-office solutions are required.
The Cisco 2800 Series offers these solutions by providing enhanced performance and increased
modular density to support multiple services at wire speed. The Cisco 2800 Series is designed
to consolidate the functions of many separate devices into a single, compact package that can
be managed remotely. Because the Cisco 2800 Series routers are modular devices, interface
configurations are easily customized to accommodate a wide variety of network applications,
such as branch-office data access, integrated switching, voice and data integration, wireless LAN
services, dial access services, VPN access and firewall protection, business-class DSL, content
networking, intrusion prevention, inter-VLAN routing, and serial device concentration. The Cisco
2800 Series provides customers with the industry's most flexible, adaptable infrastructure to meet
both today's and tomorrow's business requirements for maximum investment protection.
