5.1 Connect the VDTU2-104 Modem and the VDTU2-204 Modem to the Line 

     The objective for VDSL2 is passing data over a twisted pair cable at high speed. In 

the setup, either such a cable connects the VDTU2-104 Modem and the 
VDTU2-204 Modem, or a line simulator or any other hardware representation of a 
cable network, with or without noise injection and crosstalk simulations. 

5.2 Connect the VDTU2-104 Modem and the VDTU2-204 Modem to LAN Devices 

In the setup, usually a Ethernet tester serves as representation of the LAN side as 
well as representation of the WAN side. 

 

5.3 Run Demos and Tests 

The Ethernet tester may send data downstream as well as upstream. It also 
receives the data in order to check the integrity of the data transmission. 

Different data rates can be tested under different line conditions. 

 
 

6. Operating the VDSL2 System 

  After the VDSL2 system has been set up, you may want to configure the settings which 

  is related to VDSL2. Configuration of operation modes, test modes (loop back) and 
  the display of status information is supported by an graphical user interface. 

 

6.1 Configuration Settings 

      Configure and start the VDTU2-104 Modem and the VDTU2-204 Modem. 
   

‧

Configuration: As a minimum configuration, usually selecting the bandplan is 

required.  

See Chapter 6.1.3, Profile Configuration. 

   

‧

Next, both sides should be activated from the web interface. 

    See Chapter 6.1.6, Line Activation 
   

‧

The connection status of the link can be monitored.   
See Chapter 6.2.1, Line Status 

 
6.1.1 Channel Configuration
