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
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. Architecture Features and Benefits of Cisco 1841 Router - 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
