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.
