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 small-to-
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 hardware-based 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.
