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 mission-
critical 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 Self-
defending 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 branch-
office routers . Every Cisco 1800 Series router
