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
