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. 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, and centralized management capabilities give network managers visibility and control of router configurations at the remote site. | Product Description | Cisco 857W Integrated Services Router - router | | Device Type | Router + 4-port switch (integrated) | | Form Factor | External | | Dimensions (WxDxH) | 10.2 in x 9.1 in x 2 in | | Weight | 2.2 lbs | | Localization | United States | | RAM | 64 MB (installed) / 64 MB (max) | | Flash Memory | 20 MB (installed) / 20 MB (max) | | Routing Protocol | RIP-1, RIP-2 | | Data Link Protocol | Ethernet, ATM, Fast Ethernet, IEEE 802.11b, IEEE 802.11g | | Network / Transport Protocol | PPTP, L2TP, IPSec, PPPoE, PPPoA | | Remote Management Protocol | SNMP, Telnet, HTTP | | Digital Signaling Protocol | ADSL, ADSL2, ADSL2+ | | Features | Firewall protection, auto-sensing per device, DHCP support, NAT support, VPN support, PAT support, auto-uplink (auto MDI/MDI-X), manageable, MAC address filtering, IPv6 support | | Compliant Standards | ANSI T1.413, IEEE 802.11b, IEEE 802.11d, IEEE 802.11g, IEEE 802.1x, Wi-Fi CERTIFIED | | Power | AC 120/230 V ( 50/60 Hz ) |
