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

● Enhanced 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 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.)
