Syntax Conventions in this Guide

About Your Prestige
The Prestige is a high-performance cost-effective VDSL (Very High Speed Digital
Subscriber Line) modem. Your Prestige can access the Internet/LAN via a
telephone line. The Prestige supports symmetric and asymmetric transmission
speeds of 5, 10 and 15Mbps. The actual rate depends on the copper category of
your telephone wires, distance from the central office and the type of VDSL
service you subscribe to. Its 10/100M auto-negotiating LAN interface enables fast
data transfer of either 10Mbps or 100Mbps in half-duplex or full-duplex mode
depending on your Ethernet network. See the following section for more
background information on VDSL. Your Prestige is easy to install. You do not
need to do any configuration. All the configuration is done at the DSLAM end.
