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 851 Integrated Services Router - router | | Device Type | Router + 4-port switch (integrated) | | Form Factor | External | | Dimensions (WxDxH) | 10.2 in x 8.5 in x 2 in | | Weight | 2.2 lbs | | RAM | 64 MB (installed) / 64 MB (max) | | Flash Memory | 20 MB (installed) / 20 MB (max) | | Routing Protocol | RIP-1, RIP-2, GRE | | Data Link Protocol | Ethernet, Fast Ethernet | | Network / Transport Protocol | PPTP, L2TP, IPSec, PPPoE | | Remote Management Protocol | SNMP, RMON, Telnet, HTTP | | Features | Firewall protection, auto-sensing per device, DHCP support, NAT support, hardware encryption, VPN support, PAT support, auto-uplink (auto MDI/MDI-X), traffic shaping, IPv6 support, Weighted Fair Queuing (WFQ), Access Control List (ACL) support | | Compliant Standards | IEEE 802.1D, IEEE 802.1x | | Power | AC 120/230 V ( 50/60 Hz ) |
