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.

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.)
