Cisco Systems? is redefining best-in-class enterprise and small- to-medium-sized
business routing with a new line of integrated services routers that are optimized for the
secure, wire-speed delivery of concurrent data, voice, and video services. Founded on
20 years of leadership and innovation, the modular Cisco? 1800 Series of integrated
services routers (refer to Figure 1) intelligently embed data and security into a single,
resilient system for fast, scalable delivery of mission-critical business applications. The
best-in-class Cisco 1800 Series architecture has been specifically designed to meet
requirements of smallto-medium-sized businesses, small enterprise branch offices, and
service provider-managed services applications for delivery of concurrent services at
wire-speed performance. The integrated secure systems architecture of the Cisco 1800
Series delivers maximum business agility and investment protection.
Product Overview
Cisco 1800 Series integrated services routers are the next evolution of the award-winning Cisco
1700 Series modular access routers. The Cisco 1841 router (Figure 1) is designed for secure data
connectivity and provides significant additional value compared to prior generations of Cisco 1700
Series routers by offering more than a fivefold performance increase and integrated hardwarebased
encryption enabled by an optional Cisco IOS? Software security image. The Cisco 1841
dramatically increase interface card slot performance and density over the Cisco 1700 Series while
maintaining support for more than 30 existing WAN interface cards (WICs) and multiflex trunk
cards (voice/WICs [VWICs]for data only on the Cisco 1841 router).
The Cisco 1841 router features secure, fast, and high-quality delivery of multiple, concurrent
services for small-to-medium-sized businesses and small enterprise branch offices. The Cisco
1841 router offers embedded hardware-based encryption enabled by an optional Cisco IOS
Software security image; further enhancement of VPN performance with an optional VPN
acceleration module; an intrusion prevention system (IPS) and firewall functions; interfaces for a
wide range of connectivity requirements, including support for optional integrated switch ports; plus
sufficient performance and slot density for future network expansion and advanced applications as
well as an integrated real-time clock.
Support of high-density WICs (HWICs) is optional.
