Getting to Know Your G.SHDSL Router
This chapter covers the key features and main applications of your Prestige.
The Prestige 792H is high-performance G.SHDSL Router with four port switch for Internet/LAN access via
a telephone line. Your Prestige supports multi-protocol routing for TCP/IP, as well as transparent bridging
for other protocols.
The Prestige supports symmetrical multi-rate data transmission speeds from 72Kbps up to 2312Kbps. The
actual rate depends on the copper category of your telephone wires, distance from the central office and the
type of DSL service you subscribe to. Its 10/100M auto-negotiating LAN interface enables fast data transfer
of either 10Mbps or 100Mbps in either half-duplex or full-duplex mode depending on your Ethernet
network. See section xxi for background information on DSL.
The Prestige is also a complete security solution with a robust stateful inspection firewall and multiple
session VPN capability.
Should the Internet connection to the Prestige fail; there is a Traffic Redirect service that forwards WAN
traffic to a backup gateway.
The Prestige uses TC-PAM line code with echo cancellation for high data rate transmissions over a single-
twisted telephone wire pair without being affected by bridge taps or mixed cable links. It also provides high
immunity from background noise.
