2Overview

This document describes the steps for installing the Cisco 1801, Cisco 1802, and Cisco 1803 integrated services routers. The Cisco 1801, Cisco 1802, and Cisco 1803 routers are fixed-configuration routers. They each include an integrated 8-port 10/100-Mbps Ethernet switch, one onboard Fast Ethernet WAN port, and optional 802.11a/b/g wireless LAN support. The switch ports and the onboard 10/100-Mbps Ethernet ports support 802.1Q virtual LAN (VLAN) encapsulation and enable you to configure demilitarized zones (DMZs), using VLANs and Cisco IOS firewall features. The switch ports are also optionally upgradable to include inline power support for IP phones.

For WAN connectivity, the Cisco 1801 router has an ADSL over POTS port, the Cisco 1802 router has an ADSL over ISDN port, and the Cisco 1803 has a 4-wire G.SHDSL port. The Cisco 1801, Cisco 1802, and Cisco 1803 routers provide secure Internet connectivity and dial backup through an ISDN S/T port if your primary connection fails.

Additional information on these routers can be found on Cisco.com.
