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.
Cisco 850 Series integrated services routers offer:
• Secure connectivity with Stateful Inspection Firewall and IP Security (IPSec) VPN support for small offices
• 4-port 10/100 switch
• Secure WLAN 802.11b/g option with a single fixed antenna
• Easy setup, deployment, and remote management capabilities through Web-based tools and Cisco IOS® Software

Applications
Cisco 850 Series routers are ideally suited for small office and remote office deployments. IT managers can centrally manage the remote site to quickly troubleshoot any network issues. Optional integrated secure WLAN connectivity simplifies the number of devices that need to be managed at the remote site.
The Cisco 850 Series is ideal for managed services-service providers and value-added resellers can use the series as a platform to offer differentiated security services and business-class WLANs for small business customers.
