VDSL2      Modem    User  Manual   - 5 -  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  Figure 1.1  Interface introduction: ①  Power Interface: 12V DC,1.25A.    1 OVERVIEW

USAGE OF USB INTERFACE   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”.      7 USAGE OF USB INTERFACE
