Main Features
  • ADSL Router with 4-port 10/100 switch
Cisco 850 Series routers are ideally suited for small office and remote office deployments

These integrated services routers support broadband cable and ADSL over analog telephone lines. Designed for very small offices, the routers provide secure WAN connectivity with optional integrated wireless LAN connectivity 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 improve support for remote sites.

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. 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.
