Prestige 792H
Benefits
ZyXEL’s Prestige 792H G.SHDSL 4-port
Security Gateway is a cost-effective DSL
solution designed for medium-sized businesses
to access the Internet or remote office
networks. It integrates a high-speed DSL port,
4-port 10/100Mbps auto MDI/MDIX Ethernet
switch and Dial-Backup port to ensure
availability of the Internet. Adopting G.SHDSL
technologies, the Prestige 792H provides an
ideal high-speed alternative to leased-line
services by providing symmetric LAN-to-LAN
and Internet access transmissions at selectable
speeds of up to 2.3Mbps. It can also be
configured as either server or client mode to
provide point-to-point connectivity between
two sites.
The Prestige 792H is also a security gateway,
which protects networks by providing robust
Firewall security features and standard IPSec
Virtual Private Network tunneling. Additional
features such as auto fail-over/fall-back Dial
Backup, Traffic Redirect, and Media
Bandwidth Management will maximize
performance while minimizing operation and
maintenance cost.
Higher-speed Internet Access
The scalable G.SHDSL technology supports symmetrical multi-rate
data transmission speeds of 72Kbps to 2.3Mbps. It is a cost-effective
solution for migration from T1/E1 service. G.SHDSL technology is
ideal for applications such as web hosting, video conferencing and
the two-way data traffic needs common to businesses.
Robust Firewall Security
The ICSA certified ZyNOS operating system ensures state-of-the-art
Firewall performance and robust security from the Prestige 792H.
Based on Stateful Packet Inspection and Denial of Service (DoS),
it provides the first line of defense against hackers, network intruders,
and other hazardous threats.
VPN (Virtual Private Network) Support
The Prestige 792H supports standard IPSec VPN, suitable for site-to-
site and remote access deployment. Data encryption over the
Internet ensures secure data transmission between two sites and can
be used to replace a private leased line or frame relay network;
global interconnectivity can be achieved at a minimal expense.
Auto Fail-over and Fail-back WAN Backup Solution
The Prestige 792H supports fail-over and fail-back WAN Backup
Solution by forwarding traffic to either a backup ISDN or analog
modem in the event of DSL connection failure. When the DSL
connection is re-established, traffic returns. The Prestige 792H also
performs backup functions by redirecting traffic to a specific gateway
to ensure availability of the Internet. The WAN Backup Solution
saves device maintenance cost and minimizes daily operation loss.
Effective Media Bandwidth Management (MBM)
The Prestige 792H enables network administrators to allocate
network resources while guaranteeing Quality of Service (QoS).
The MBM (Media Bandwidth Management) function prioritizes
media services, increasing productivity and efficiency in daily
operation by tailoring a system to specific demands such as VoIP,
video streaming, videoconferencing and MP3 applications.
