Cisco 1801, 1802, 1803, 1811, and 1812 Integrated Services Routers
The Cisco 1801, 1802, 1803, 1811, and 1812 integrated services routers are fixed-configuration routers designed for secure broadband, Metro
Ethernet, and wireless connectivity. They provide significant performance improvements, feature capability, versatility, and additional value
compared to prior generations of the Cisco 1700 Series. The Cisco 1800 Series fixed-configuration routers provide:
•
Secure broadband access at wire-speed performance for branch and small offices
•
Integrated ISDN Basic Rate Interface (BRI), analog modem, or Ethernet backup port for redundant WAN links and load balancing
•
Secure WLAN option for simultaneous 802.11a and 802.11b/g with use of multiple antennas
•
Advanced security, including:
–
Stateful inspection firewall
–
IPSec VPNs (3DES or AES)
–
IPS
–
Antivirus support through NAC and enforcement of secure access policies
•
Eight-port 10/100 managed switch with VLAN support and optional Power over Ethernet (PoE)
•
Easy deployment and remote-management capabilities through Web-based tools and Cisco IOS Software
Cisco 1801, 1802, and 1803 routers provide high-speed DSL broadband access through ADSL over basic telephone service (Cisco 1801), ADSL
over ISDN (Cisco 1802), or G.SHDSL (Cisco 1803) while helping 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 they also provide
integrated WAN backup through a V.92 analog modem (Cisco 1811) or ISDN S/T BRI interface (Cisco 1812). (Refer to Table 3.)
