OVERVIEW
1. OVERVIEW
1.1 ABOUT VDSL
VDSL is a fast version of ADSL.VDSL MODEM is a broadband Internet access device，which utilizes
the high frequency segment of the phone line to transmit high-speed data without interfering with the voice
transmission. The frequency of VDSL signal is higher than that of voice, so voice and VDSL signal can coexist
in one line by using a splitter to insulate each from the other. VDSL data transfer on the asymmetry way. The
upload speed is up to 19.2Mbps and download speed is up to 55Mbps. It is an ideal device for broadband
access.
1.2 DEVICE INTRODUCTION

PPPoE is also known as RFC 2516. It is a method of encapsulating PPP packets over Ethernet.
PPPoA is also known as RFC2364 and named as Peer to Peer Protocol over ATM. As PPPoE, it also has all
the features of PPP. Although it’s based on ATM protocol, the setting of all the other parameters is similar with
PPPoE. So we only introduce PPPoE in detail here.

USAGE OF USB INTERFACE
7. USAGE OF USB INTERFACE
ZXDSL 831AII User Manual
The Combo DSL Gateway is a device with both Ethernet Interface and USB Interface, which is
independent, you may use either of them to connect to the different computers, in this way the two computers
can connect to the network at one time. The Gateway can be seen as a simple two-port HUB. So, do not
connect both the Ethernet Interface and USB Interface to a same computer.
When using USB Interface, you must install the drivers. After installation, a virtual network card, "USB
Remote NDIS Network Device", will be added into the computer. It has all the functions of a real network
card, and it makes installation more easily.
NOTES:
The following shows the steps for Windows®2000, the installation, configuration and uninstallation of
Windows®98 or Windows®XP are similar to this.
7.1 DRIVER INSTALLATION
1. Open the Modem, and connect the USB port. Then double click “Setup.exe” in “G:\Driver\” . You will
enter the DSL MODEM Setup Wizard as figure 7.1.1, click “Next”.
