Cisco 880G Series
Cisco 880 Series Integrated Services Router
Cisco® 880 Series Integrated Services Routers are the next generation of fixed-configuration routers that provide collaborative business solutions for secure
data communication to enterprise branch offices,
small businesses, and teleworkers (Figure 1).
Cisco integrated services routers offer a network
foundation of integrated services and embedded
intelligence to facilitate:
• Rapid deployment of secure connectivity, voice, and wireless solutions by simply activating new services as required without incurring new
equipment costs
• Simplified operations by managing services
using common tools and interfaces
• Protection of business assets by deploying integrated routing systems with embedded security services that protect both wired and wireless connections
• Reduction of capital expenditures and operatingexpenses by eliminating the need to deploy
and manage new equipment in order to support new services
