1812 Integrated Services Routers are fixed-
configuration, while the Cisco 1841 Integrated
Services Router is modular The routers are
designed for secure broadband, Metro Ethernet,
and wireless connectivity, and provide significant
performance improvements, feature capability,
versatility, and additional value compared to prior
generations of Cisco 1700 Series The Cisco
1800 Series fixed-configuration routers provide:
• Secure broadband access with concurrent
services for branch and small ofces
• Integrated ISDN Basic Rate S/T Interface (BRI),
analog modem, or Ethernet backup port for
redundant WAN links and load balancing
• Secure wireless LAN option for simultaneous
80211a and 80211b/g with use of two dual-
mode antennas
• Advanced security including: Stateful
Inspection Firewall, IP Security (IPSec) VPNs
(Triple Data Encryption Standard [3DES] or
Advanced Encryption Standard [AES]), Intrusion
Prevention System (IPS), Antivirus support
through Network Admission Control (NAC) and
enforcement of secure access policies
• 8-port 10/100 managed switch with 8021q
VLAN support and optional Power over
Ethernet (PoE)

Cisco IOS 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)
