High Performance Secure Internet Access
Improve Management with an Integrated V.92 Interface
Cisco 890 Series Integrated Services Routers are designed to deliver highly secure broadband, Metro Ethernet, wireless LAN connectivity, and business continuity for enterprise small branch offices. These fixed-configuration routers also come with powerful management tools, such as the web-based Cisco Configuration Professional, which simplifies setup and deployment. The Cisco 891 model includes an integrated V.92 analog modem interface.
Cisco 891 Series Integrated Services Routers offer:
- High performance for secure broadband and Metro Ethernet access
- Business continuity and WAN diversity with redundant WAN links (Fast Ethernet, V.92)
- Secure 802.11a/g/n access point (optional), which offers dual-band radios for mobility, and supports Cisco Unified WLAN architectures
- Enhanced security, including:
- Firewall with advance application and control
- Site-to-site remote-access and dynamic VPN services, including IP Security (IPsec) VPNs, Group Encrypted Transport VPN [GET VPN] with onboard acceleration, and Secure Sockets Layer [SSLVPN]
- Intrusion prevention system (IPS)
- Content filtering
- An 8-port 10/100 Fast Ethernet managed switch with VLAN support and 4-port support for Power over Ethernet (PoE) (optional)
- Metro Ethernet features that include:
- One 1000 BASE-T Gigabit Ethernet and One 10/100 BASE-T Fast Ethernet WAN port
- Intelligent hierarchical quality of service (HQoS)
- Connectivity Fault Management (CFM), link operational administration and maintenance (OAM), and Ethernet Local Management Interface (E-LMI) for the Customer Edge
- IP service-level agreement (SLA) for Metro Ethernet
