security image and the flexibility to integrate a wide array of services, modules, and interface
cards, the Cisco 1841 router helps enable businesses to incorporate the functions of a standalone
secure data solution.
Primary Features and Benefits
Architecture Features and Benefits
The Cisco 1841 modular architecture has been specifically designed to meet requirements of
small to medium-sized businesses and small enterprise branch offices as well as service provider-
managed applications for concurrent services at wire-speed performance. The Cisco 1841 router,
together with other Cisco integrated services routers such as the Cisco 2800 Series, provide the
broadest range of secure connectivity options in the industry combined with availability and
reliability features. In addition, Cisco IOS Software provides support for a complete suite of
transport protocols, quality of service (QoS), and security. Table 1 gives the architecture features
and benefits of the Cisco 1841 router.
Table 1. Architecture Features and Benefits of Cisco 1841 Router
Feature Benefit
High-Performance Processor
Supports concurrent deployment of high-performance, secure data services with
headroom for future applications
Modular Architecture
Offers wide variety of LAN and WAN options; network interfaces are field-
upgradable to accommodate future technologies
Provides many types of slots to add connectivity and services in the future on an
"integrate-as-you-grow" basis
Supports more than 30 modules and interface cards, including existing WAN
(WIC) and multiflex (VWIC) interface cards (for data support only on the Cisco
1841 router) and advanced integration modules (AIMs)
Integrated Hardware-Based
Encryption Acceleration
Offers cryptography accelerator as standard integrated hardware that can be
enabled with an optional Cisco IOS Software for 3DES and AES encryption
support
Provides enhanced feature set of security performance through support of
optional VPN acceleration card for VPN 3DES or AES encryption
Ample Default Memory
Provides 32 MB of Flash and 128 MB of synchronous dynamic RAM (SDRAM)
memory to support deployment of concurrent services
Integrated Dual High-Speed
Ethernet LAN Ports
Helps enable connectivity speeds up to 100BASE-T Ethernet technology without
the need for cards and modules
Allows segmentation of the LAN
Support for Cisco IOS 12.3T,
12.4, 12.4T Feature Sets and
Beyond

Modularity Features and Benefits
The Cisco 1841 router provides enhanced modular capabilities while protecting customer
investments. The modular architecture has been designed to provide the increased bandwidth and
performance required to support concurrent, secure applications. Most existing WICs, multi-flex
trunk interface cards (for data only), and Advanced Integration Modules (AIMs) are supported in
the Cisco 1841. Table 2 lists the modularity features and benefits of the Cisco 1841 router.
