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.
