Cisco 890 Series Integrated Services Routers offer the following:
• The routers offer high performance for secure broadband and Metro Ethernet access with concurrent services for enterprise small branch offices.
• They provide business continuity and WAN diversity with redundant WAN links: Fast Ethernet (FE), V.92, ISDN Basic Rate Interface (BRI), Gigabit Ethernet (GE), ADSL2+/VDSL (Annex A/B/M), Multimode G.SHDSL, and Small Form-Factor Pluggable (SFP).
• An integrated secure 802.11a/g/n access point (optional) is based on the draft 802.11n standard. Dual-band radios allow for mobility and support for autonomous or Cisco Unified WLAN architectures.
• The routers offer enhanced security including:
– Firewall with advance application and control for email, instant messaging (IM), and HTTP traffic
– Site-to-site remote-access and dynamic VPN services: IP Security (IPsec) VPNs (Triple Data Encryption Standard [3DES] or Advanced Encryption Standard [AES], Dynamic Multipoint VPN [DMVPN], Group Encrypted Transport VPN with onboard acceleration, and Secure Sockets Layer [SSL] VPN)
– Intrusion prevention system (IPS): An inline, deep-packet-inspection feature that mitigates a wide range of network attacks
– Web security with Cisco ScanSafe deployment
• The 8-port 10/100 Fast Ethernet managed switch offers VLAN support and 4-port support for Power over Ethernet (PoE) (optional for certain models) to power IP phones or external access points. The Cisco 892FSP, 896VA, 897VA, 898EA, and 891F have an 8-port 10/100/1000 Gigabit Ethernet managed switch with VLAN support. No PoE support is available for the Cisco 892FSP. For the PoE option on the Cisco 896VA, 897VA, 898EA, and 891F models, there is a 125W power supply adapter to power the unit and the 4 PoE ports. On the Cisco 891 and 892 a second 80W power supply adapter provides power to the PoE ports.
• Metro Ethernet features include:
– One 1000BASE-T Gigabit Ethernet WAN port
– One 10/100BASE-T Fast Ethernet WAN port on the Cisco 891, 892, and Cisco 891F or 1-port Gigabit Ethernet WAN port on the Cisco 892FSP, 896VA, 897VA, and 898EA
– One 1-port Gigabit Ethernet SFP socket for WAN connectivity on the Cisco 892F, 892FSP, 896VA, 897VA, 898EA, and 891F
( Note: Only the 1000BASE-T Gigabit Ethernet WAN or the SFP is operational at a given time.)
– Intelligent hierarchical quality of service (HQoS): Support for hierarchical queuing and shaping
– Connectivity Fault Management (CFM), based on 802.1ag
– 802.3ah standards-based link operations, administration, and maintenance (OA&M)
– Ethernet Local Management Interface (E-LMI) for the customer edge
– CFM Interworking and backward compatibility
– Performance management based on IP service-level agreement (SLA) for Ethernet
• Dedicated console and auxiliary ports for configuration and management.
• Two USB 2.0 ports for security eToken credentials, booting, and loading configuration from USB available on the Cisco 891, 892, and 892F.
• Cisco 892FSP, 896VA, 897VA, 898EA, and 891F are fanless, providing a quiet, comfortable working environment in small offices.
• One USB 2.0 port for booting and loading configurations from the USB port is available on the Cisco 892FSP, 896VA, 897VA, 898EA, and 891F.
• Easy to set up and deploy, the Cisco 890 ISRs offer centralized and remote-management capabilities through web-based tools and Cisco IOS® Software.
