Cisco 850 Series Integrated Services Routers
for Small Offices
The Cisco® 850 Series of secure broadband and wireless routers is part of the Cisco
Integrated Services Router portfolio. Designed for small offices, the routers provide
secure WAN connectivity with optional integrated 802.11b/g WLANs in a single device.
Easy setup allows the Cisco 850 Series to be deployed at small remote offices and small
businesses, and remote management features enable IT managers and service providers
to provide better support at remote sites.
Product Overview
Cisco 850 Series integrated services routers are fixed-configuration routers that support
broadband cable and Asymmetric DSL (ADSL) over analog telephone lines connections in small
offices (Figures 1 and 2). They provide the performance needed to run concurrent services,
including firewall and encryption for VPNs and optional 802.11b/g for wireless networking. The
Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup
and deployment (Figure 3), and centralized management capabilities give network managers
visibility and control of router configurations at the remote site.
