ZyXEL p-792h Guia De Especificação

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.

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.

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.

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.

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. 

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.
