Based on 20 years of innovation, Cisco 3800 Integrated Services Routers extend Cisco Systems’ leadership in multiservice routing by providing customers with unparalleled network agility, performance, and intelligence. By transparently integrating advanced technologies, adaptive services, and secure enterprise communications into a single, resilient system Cisco 3800 routers offer simplified deployment and management, help lower the costs and complexities of your network, and provide enhanced investment protection. The integrated services routing architecture of the Cisco 3800 product family builds on the powerful Cisco 3700 Series Multiservice Access Routers and adds embedded security processing, significant performance and memory enhancements, and new high-density interfaces that deliver the performance, availability, and reliability required for scaling mission-critical business applications in the most demanding enterprise environments. Cisco 3800 Integrated Services Routers support the bandwidth requirements for multiple Fast Ethernet interfaces per slot, time-division multiplexing (TDM) interconnections, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE), while still supporting the existing portfolio of modular interfaces. This helps to ensure the delivery of continued investment protection to account for network expansion or changes in technology as new services and applications are deployed.
