Cisco 3800 Series Integrated Services Routers

SYSTEM OVERVIEW

What is the Cisco

3800 Series?

The Cisco 3800 Series extends Cisco Systems’ leadership in multiservice routing with a new family of routers that offers the network the

agility, performance, and intelligence needed to meet customers’ rapidly evolving network and business challenges. The Cisco 3800 Series is the

flagship platform in a portfolio of next-generation routers that integrate advanced technologies, adaptive services, and secure enterprise

communications. These new routers offer the performance and reliable packet delivery necessary to efficiently deliver mission-critical network

capabilities, including real-time applications such as VoIP, business video, and collaborative communications. Architectural enhancements include

embedded security processing, significant platform performance and memory improvements, and new high-density interface types. These design

achievements complement the Cisco IOS

Software features and superior investment protection that this platform inherits from the Cisco 3700

Series. The Cisco 3800 Series, comprised of the Cisco 3825 and Cisco 3845 (Figures 1 and 2), serves as a catalyst for midsize organizations and

enterprise branch offices that want to gracefully scale their enterprise edges and take advantage of converged business services, while minimizing the

cost and complexity of network upgrades.

The Cisco 3800 Series offers two new modular platforms optimized for the secure delivery of concurrent voice, video, data, and wireless. The

integrated services architecture of the Cisco 3800 Series builds on the highly successful Cisco 3700 Series design, and adds embedded security and

voice processing to a highly modular system that is optimized for rapid deployment of intelligent network services and converged communications.

The Cisco 3800 Series supports 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 supporting the existing

portfolio of modular interfaces. This helps to ensure continuing investment protection to accommodate network expansion or changes in technology

as new services and applications are deployed. By integrating the functions of multiple separate devices into a single, compact unit, Cisco 3800

Series integrated services routers dramatically reduce the cost and complexity of managing remote networks.
