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.
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.
