Notes 52 Cisco 1800 Series (Cisco 1841 Router Modular) Cisco is redefining best-in-class enterprise and small- to medium-sized business (SMB) routing with a line of Integrated Services Routers that are optimized for the secure, wire-speed delivery of data services. Founded on 20 years of leadership and innovation, Cisco 1800 Series Integrated Services Routers intelligently embed data and security into a single, resilient system for fast, scalable delivery of missioncritical business applications. The Cisco 1800 Series architecture has been specifically designed to meet requirements of SMBs, small enterprise branch offices, and service-provider-managed services applications for delivery of concurrent secure data services at wire-speed performance. The integrated, secure systems architecture of the Cisco 1800 Series delivers maximum business agility and investment protection. Benefits and Advantages Enhanced Architecture The Cisco 1841 Integrated Services Router provides secure data connectivity at up to one T1/E1/xDSL WAN connectivity rates. It provides significant additional value compared to prior generations of Cisco 1700 Series routers by offering more than a five-fold performance increase, integrated onboard hardware-based encryption enabled by an optional Cisco IOS Software security image, and a dramatic increase in interface card slot performance and density. Support for one internal Advanced Integration Module (AIM) slot is provided for additional hardware-accelerated encryption and scalability. The modular architecture on the Cisco 1841 router also supports two high-speed WAN interface card (HWIC) slots which significantly increase data-throughput capability (up to 800 Mbps aggregate). The Cisco 1841 also offers integrated dual high-speed Ethernet LAN ports to allow LAN segmentation and to help enable connectivity speeds up to 100BASE-T Ethernet technology. Ample default memory (Flash, SDRAM) is provided to support deployment of concurrent services. Flexibility and Investment Protection The modular architecture of the Cisco 1841 router offers a wide variety of LAN and WAN options; interface cards and modules are field-upgradable to accommodate future technologies. The Cisco 1841 delivers investment protection with support for more than 30 modules and interface cards, including existing WICs and voice WAN interface cards (VWICs-on the Cisco 1841 router for data support only) as well as Advanced Integration Modules (AIM). This Integrated Services Router provides 2 slots that are WIC/HWIC/VWIC (data) capable and enables multiple services on an integrate-as-you-grow basis. Market-leading Integrated Security A primary component of the Cisco Selfdefending Network, the Cisco 1841 Integrated Services Router ships with the industry's most comprehensive security services embedded within the router that can be enabled with a Cisco IOS Security Image. This provides customers with a single, resilient platform to rapidly deploy secure networks and applications. The Cisco 1800 Series was designed with integrated security to provide a tight coupling among security, routing, and other integrated services throughout the network. With a Cisco IOS Software-based VPN, firewall, and intrusion prevention system (IPS), as well as optional enhanced VPN acceleration, and Network Admission Control (NAC) support for anti-virus defense, the Cisco 1841 offers a robust and adaptable security solution for branchoffice routers. Every Cisco 1800 Series router comes with the factory-installed Cisco Router and Security Device Manager (SDM). Cisco SDM is an 53
