Summary
As companies increase their security requirements and their need for integrated services, more
intelligent branch-network solutions are required. The best-in-class Cisco 1800 Series architecture
has been specifically designed to meet these requirements for secure concurrent services at wire-
speed performance. The Cisco 1800 Series integrated services routers, consisting of the Cisco
1801, 1802, 1803, 1811, 1812, and 1841 routers, offer the opportunity to consolidate the functions
of separate devices into a single, compact solution that can be remotely managed. By providing
integrated services and high performance, the Cisco 1800 Series routers deliver security,
versatility, scalability, and flexibility to deploy multiple applications in the small to medium-sized
office and small enterprise branch office, and the service provider customer edge. The Cisco 1800
Series easily accommodates a wide variety of network applications, such as secure branch-office
data access with broadband and Ethernet access including NAC for antivirus defense, VPN
access and firewall protection, PoE support, inter-VLAN routing and support deployment of secure,
enterprise-class WLANs. These routers give customers the industry's most flexible, secure, and
adaptable infrastructure to meet both today's and tomorrow's business requirements for maximum
investment protection.
