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
