CISCO 870 SERIES INTEGRATED SERVICES ROUTERS
FOR SMALL OFFICES
The Cisco® 870 Series Integrated Services Routers extend the high-performance Cisco Integrated Services Router
capabilities of running secure concurrent services, including firewall, VPNs, and WLANs, at broadband speeds to small
offices. Easy deployment and centralized management features enable the Cisco 870 Series to be deployed in small office or
teleworker sites as part of an enterprise network, by small to medium business customers for secure WAN and WLAN
connectivity, or used by service providers to offer business-class broadband and WLAN services.
PRODUCT OVERVIEW
Cisco 870 Series of integrated services routers are fixed-configuration routers that support multiple types of DSL technologies, broadband cable, and
Metro Ethernet connections in small offices (Figures 1 and 2). They provide the performance needed to run concurrent services, including firewall,
intrusion prevention, and encryption for VPNs; optional 802.11b/g for WLAN networking; and quality of service (QoS) features for optimizing voice
and video applications. In addition, the Cisco Router and Security Device Manager (SDM) Web-based configuration tool simplifies setup and
deployment (Figure 3), and centralized management capabilities give network managers visibility and control of the network configurations at the
remote site.
Cisco 870 Series integrated services routers offer:
• High performance for broadband access in small offices
• Advanced security, including:
– Stateful Inspection Firewall
– IP Security (IPSec) VPNs (Triple Data Encryption Standard [3DES] or Advanced Encryption Standard [AES])
– Intrusion prevention system (IPS)
– Antivirus support through Network Admission Control (NAC) and enforcement of secure access policies
• 4-port 10/100 managed switch with VLAN support
• Secure WLAN 802.11b/g option with use of multiple antennas
• Easy setup, deployment, and remote management capabilities through Web-based tools and Cisco IOS® Software

The Cisco 870 Series is ideal for small remote offices and teleworkers that need to be connected to larger enterprise networks. When extending
corporate networks to numerous remote sites, network resources must remain secure while giving users access to the same applications found in a
corporate office. This applies to both data and voice applications, where IP phones can be used to extend a corporate voice extension to the remote
office. When users require WLAN access, visibility and control of network security is even more critical at the remote site. The Cisco 870 Series
meets this need with a single device that combines integrated 802.11b/g capabilities with security features such as Wi-Fi Protected Access (WPA),
including authentication with IEEE 802.1X with Cisco Extensible Authentication Protocol (LEAP) and Protected EAP (PEAP), and encryption with
WPA Temporal Key Integrity Protocol (TKIP). (See Wireless Solution overview and Security Data Sheet for more information).
Service providers and value-added resellers can take advantage of the Cisco 870 Series to provide a true business-class broadband service. Business
customers are using broadband access to connect to the Internet or to connect offices together, and require a platform that incorporates security
without sacrificing performance. Many of these customers are connecting computers in offices through WLANs; having a single device for both
WAN and WLAN access provides a new option for managed services. These customers also require a higher level of support to keep their networks
up and running. Services with these customers should be simple to set up, while allowing a level of remote management and troubleshooting to more
quickly address support inquiries. The Cisco 870 Series meets the requirements of small offices and managed services providers.

Figure 2. Deployment Scenarios
APPLICATIONS
The Cisco 870 Series is ideally suited to be deployed where a small office is going to be connected to a larger network, most often with a secure VPN
connection. These types of offices can include the following:
• Small Remote Office—Connects users in a small remote office, such as insurance agents, lawyer offices, or sales offices. When connecting to the
main office, VPN encryption and integrated security such as firewall, and intrusion prevention protect the network at every perimeter. IT managers
can centrally manage the remote site to quickly troubleshoot any network issues. For added reliability, customers can also use dial backup, through
an external modem, should the primary broadband link fail. Integrated secure WLAN connectivity simplifies the number of devices that need to be
managed at the remote site.
• Teleworking—The Cisco 870 Series is ideal for corporate teleworkers who may have a mix of broadband connection types to choose from. A
platform such as the Cisco 870 Series gives IT managers a standard platform to manage at the employee’s home office. QoS features in the Cisco
870 Series allow an IP phone to be connected to the router, giving voice traffic precedence over data applications. Integrated WLAN support in
the Cisco 870 Series helps ensure that if wireless connectivity is to be used, it can be done securely. (See Cisco Business Ready Teleworker
Solutions for more information.)
