Software
Cisco 1801, 1802, and 1803 routers provide high-speed DSL broadband access through asymmetric DSL (ADSL) over basic telephone service
(Cisco 1801), ADSL over ISDN (Cisco 1802), or Symmetrical High-Data-Rate DSL (G.SHDSL) (Cisco 1803) while helping to ensure reliable
networking with integrated ISDN S/T BRI backup. The Cisco 1811 and 1812 provide high-speed broadband or Ethernet access through two
10/100BASE-T Fast Ethernet WAN ports and also provide integrated WAN backup through a V.92 analog modem (Cisco 1811) or ISDN S/T BRI
interface (Cisco 1812).
The Cisco 1800 Series fixed-configuration routers help enable a network infrastructure for SMBs and enterprise small branch offices, providing
access to the Internet, corporate headquarters, or other remote offices, while securing and protecting critical data with integrated Cisco IOS Software
security features and capabilities. They also help businesses reduce costs by enabling deployment of a single device to provide multiple services
(integrated router with redundant link, LAN switch, firewall, VPN, IPS, wireless technology, and quality of service [QoS]) typically performed by
separate devices. Cisco IOS Software allows this flexibility, providing the industry’s most robust, scalable, and feature-rich internetworking support,
using the accepted standard networking software for the Internet and private WANs.

NETWORK APPLICATIONS
Secure Network Connectivity
Network security has become a fundamental building block of any network, and Cisco routers play an important role in embedding security at the
customer’s access edge. Recognizing this requirement, the Cisco 1800 Series fixed-configuration routers are equipped with the Cisco IOS Software
Advanced IP Services feature set by default (except for the Cisco 1801). This Cisco IOS Software feature set facilitates hardware-based IPSec
encryption on the motherboard and provides a robust array of security capabilities such as Cisco IOS Firewall, URL Filtering, IPS support, IPSec
VPNs (DES, 3DES, and AES), Dynamic Multipoint VPN (DMVPN), Easy VPN server and client support, NAC for defense against worms and
viruses, security policy enforcement, Secure Shell (SSH) Protocol Version 2.0, and Simple Network Management Protocol (SNMP) in one solution
set. As Figure 2 demonstrates, the Cisco 1800 Series fixed-configuration routers help enable customers to deploy high-performance, concurrent,
mission-critical data applications with integrated, end-to-end security.
