CHAPTER 1
Introducing the VMG
1.1 Overview
The following table describes the feature difference of the VMG by model.
The VMG is a VDSL modem, which provides fast Internet access over a plain telephone wire. After you
make the connections and turn it on, the VMG can automatically access the Internet. Refer to Section
18.3 on page 68 if you cannot access the Internet.
It also supports VDSL bonding that allows the combining of DSL connections for even faster speeds.
Universal Plug and Play (UPnP) where UPnP devices can dynamically join the VMG network is also
supported.
You can use the Web Configurator to view traffic statistics, upload firmware and allow external
management of the VMG.
1.2 Example Applications
This section shows a few examples of using the VMG in various network environments. Note that the
VMG in the figure is just an example VMG and not your actual VMG.
1.2.1 Internet Access
Your VMG provides shared Internet access by connecting the DSL port to the DSL or MODEM jack on a
splitter or your telephone jack. You can have multiple WAN services over one ADSL or VDSL. The VMG
cannot work in ADSL and VDSL mode at the same time.
A computer, gateway, or router can connect to the VMG’s LAN port.
