CISCO857W-G-A-K9 router new and original

Product Type: Wireless DSL Router
Connectivity Media: Twisted Pair
The 857W ADSL Integrated Services Wireless Router supports broadband cable and Asymmetric DSL (ADSL) over analog telephone lines connections in small offices. It provides the performance needed to run concurrent services, including firewall and encryption for VPNs and 802.11b/g for wireless networking. The Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup and deployment, and centralized management capabilities give network managers visibility and control of router configurations at the remote site.
