VDSL2 Point to Point Solution
VDSL2 (Very-High-Bit-Rate Digital Subscriber Line 2, ITU-T G.993.2 Standard) is an
access technology that exploits the existing infrastructure of copper wires that were
originally deployed for POTS services. It can be deployed from central offices, from
fibre-fed cabinets located near the customer premises or within buildings.
ITU-T G.993.2 VDSL2 is the newest and most advanced standard of DSL
broadband wireline communications. Designed to support the wide deployment of
Triple Play services such as voice, video, data, high definition television (HDTV) and
interactive gaming. VDSL2 enables operators and carriers to gradually, flexibly and
cost efficient upgrade on existing xDSL-infrastructure.
ITU-T G.993.2 (VDSL2) is an enhancement to G.993.1 VDSL that permits the
transmission of asymmetric and symmetric (Full-Duplex) aggregate data rates up to
200 Mbit/s on twisted pairs using a bandwidth up to 30 MHz.
VDSL2 deteriorates quickly from a theoretical maximum of 250 Mbit/s at 'source' to
100 Mbps at 0.3 km and 50 Mbps at 1 km, but degrades at a much slower rate from
there and still outperforms VDSL. Starting from 1.6 km its performance is equal to
ADSL2+.

Attention: The settings in the following Chapter 4.4 only need to be performed
in order to change LAN settings. Such a change may be necessary when
connecting the VDSL2 VC-400LT/VC-400RT Router to a new control PC and/or
in order to turn the IP address changed via a shell command into a default
address for the next restart of the board.
4.4 Select LAN
The menu below will not be used very often, but when connecting the VDSL2
VC-400LT/VC-400RT Router to a new control PC, one may want to go through
the following steps in order to make the IP address previously set by ifconfig in
the console or on some later occasion one may want to change it again without
using the console then the menu below will be helpful. In order to set the IP
address, click on “LAN Settings”.

Figure 4.4 LAN menu
4.4.1 Select LAN Settings and set the IPAddress
The form below is used to change the IP address of the LAN port “adm0” in the
VDSL2 VC-400LT/VC-400RT Router.
The proposed IP address is either the default address of adm0 or it is the
address changed by an ifconfig command via the shell running in the terminal.
The Subnet Mask display can be ignored. In case the DHCP checkbox is
checked, some additional data and options will be on display (see Chapter
8.2.5.1 on Page 70). The DHCP server is not required to work with VDSL2 in a
lab environment. It recommend to uncheck the box if it is not unchecked
already.

Now the IP address either may be changed or left as it is. If it has been
changed in the form or after it has been changed through console ifconfig
command, it needs to be “APPLY” in order to make the displayed IP address
new default address.

4.4.2 Restart the Settings Dialog
After the “APPLY” button has been hit, the displayed IP address “adm0” port will
be stored in a non volatile memory on the VDSL2 VC-400LT/VC-400RT Router.
Also, the Ethernet link between the control PC and the VDSL2
VC-400LT/VC-400RT Router will be re-initialized – even if the IP address has
not been changed. Refresh the display of the HTTP browser running on the
control PC and login again.

6. Building a VDSL2 System
First a quick overview on a complete setup of VDSL2 VC-400LT/VC-400RT Router.
Figure 6 VDSL2 Application
6.1 Connect the VDSL2 VC-400LT and VC-400RT ROUTER to the Line
The objective for VDSL2 is to pass high speed data over a twisted pair cable. In
the setup, connects VDSL2 VC-400LT Router to VDSL2 VC-400RT Router
through phone wire or line simulator or any other hardware representation of a
cable network, with or without noise injection and crosstalk simulations.
