CISCO 830 SERIES SECURE BROADBAND ROUTERS

Advanced security for data, voice, and video access ideal for small oﬃces and teleworkers.

The Cisco® 830 Series of secure broadband routers is ideal for providing secure Internet and corporate network connectivity to small remote oﬀices

and to teleworkers. Cisco 830 Series routers provide a wide range of integrated security services and advanced quality of service (QoS) features for

high-quality data, voice, and video applications. They oﬀer easy deployment and remote management features with Cisco IOS® Software.

Figure 1. The Cisco 830 Series Router

The Cisco 830 Series is comprised of the Cisco 831 Ethernet Broadband Router, the Cisco 836 ADSL over ISDN Broadband Router with an ISDN

BRI port, and the Cisco 837 ADSL Broadband Router. The Cisco 831 router has an Ethernet WAN port for use with an external digital subscriber

line (DSL) or cable modem. The Cisco 836 router supports asymmetric DSL (ADSL) over Integrated Services Digital Network (ISDN). The Cisco

837 router supports ADSL over POTS (basic telephone service). All models oﬀer a four-port 10/100 Ethernet LAN switch for connecting multiple

PCs or network devices in a small-oﬀice network.

ADVANCED SECURITY AND PERFORMANCE FOR ENTERPRISE-CLASS VPNs

The Cisco 830 Series delivers integrated enterprise-class security services, including hardware-accelerated IP Security (IPSec), Triple Data

Encryption Standard (3DES) encryption for virtual private networks (VPNs), and stateful-inspection ﬁrewall for secure Internet connectivity.

Optional advanced features—such as OSPF, RIP, and RIP v2, EIGRP and BGP (limited) routing protocols; Cisco Easy VPN Remote (a software

feature that allows simple deployment and management of VPNs) and Easy VPN Server (limited to ﬁve users); public key infrastructure (PKI)

security requiring digital certiﬁcates; IPSec Network Address Translation transparency (NAT-T); the Cisco Intrusion Detection System (IDS);

WCCP and URL ﬁltering—help ensure that the small oﬀice receives the highest level of security, which contributes to the corporate network’s

security.

HIGH-QUALITY, SECURE VOICE AND VIDEO

The advanced QoS and high-performance encryption features oﬀered in Cisco 830 Series routers provide high-quality voice and video services to

remote users. When IP phones are connected at a remote site, a Cisco 830 Series router can queue and prioritize the voice traﬀic over data traﬀic to

ensure a high-quality, secure voice-over-IP (VoIP) connection from the remote or home oﬀice back to the corporate network.

MANAGEABLE, SCALABLE, AND RELIABLE ACCESS

The Cisco 830 Series uses valuable management and deployment tools to deliver the industry’s lowest total cost of ownership for connecting small

remote oﬀices and teleworkers to the corporate network. As a remotely manageable platform, the Cisco 830 Series supports advanced remote

troubleshooting commands available in Cisco IOS Software; a virtual auxiliary (AUX) port for out-of-band management with an external modem

or through an integrated ISDN Basic Rate Interface (BRI) ISDN port (Cisco 836 router); and Secure Shell (SSH) Protocol for secure in-band
