Think IT (Network) :: Cisco 830 Series Secure Broadband Routers

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 management via Telnet. Cisco 830 series routers come equipped with two embedded remote management tools, Cisco Security Device Manager (SDM) and Cisco Router Web SetUp Tool (CRWS).

For scalability in deployment and management, the Cisco Router Web SetUp Tool, available in several languages, allows nontechnical users to quickly set up the router and turn on key features such as the stateful firewall. Cisco Security Device Manager provides added functionality for Web-based security and router set up and monitoring. Cisco provides a suite of solutions-such as Cisco Easy VPN, the Cisco IE 2100 Intelligence Engine, Cisco VPN Solution Center (VPNSC), the CiscoWorks Router Management Center (Router MC) and Cisco Configuration Express-that allow for scalable network deployment and management, including automated security policy push and configuration updates.

For reliable access, the virtual AUX port on Cisco 831, 836, and 837 routers can be used for dial backup with an external modem, should the primary WAN connection fail. On the Cisco 836 router, an integrated ISDN BRI S/T port also provides ISDN dial backup and out-of-band management. The Cisco 830 Series runs Cisco IOS Software, the industry-proven software that has become the standard for reliable business access.

FEATURES AND BENEFITS

Table 1. Key Product Features and Benefits
