Cisco 1801, 1802, and 1803 routers provide high-speed DSL broadband access through
asymmetric DSL (ADSL2/2+ Annex A and Annex M) over basic telephone service (Cisco 1801),
ADSL2/2+ Annex B 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.
