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.

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.

Architecture Features and Benefits of Cisco 1841 Router

Benefit
● Supports concurrent deployment of high-performance, secure data services with headroom for future
applications
● 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)
● 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
● Provides 32 MB of Flash and 128 MB of synchronous dynamic RAM (SDRAM) memory to support deployment
of concurrent services
● Helps enable connectivity speeds up to 100BASE-T Ethernet technology without the need for cards and
modules
● Allows segmentation of the LAN
● Supports the Cisco 1841 router starting with Cisco IOS Software Release 12.3T
● Helps enable end-to-end solutions with support for latest Cisco IOS Software-based QoS, bandwidth
management, and security features
● Provides for easier installation and management of the router platform

Modularity Features and Benefits of Cisco 1841 Router

Benefit
● The modular architecture on the Cisco 1841 router supports HWIC slots. The newly designed high-speed
WAN interface slots significantly increase the data-throughput capability (up to 800-Mbps aggregate). Table 6
lists the High Speed WAN Interface cards supported on the Cisco 1841.
● Both slots on the Cisco 1841 router are HWIC slots and provide compatibility with WICs and multiflex trunk
(VWICs) interface cards
(for data only).
● The Cisco 1841 router supports hardware-accelerated encryption through AIM modules (AIM-VPN/SSL-1)
and intrusion prevention through AIM-IPS-K9 module
● The Cisco 1841 router has one internal AIM slot.
