1.2 Introduction To Ethernet over VDSL
Converter
General Description
The converter is a switching architecture with four RJ45
10/100Mbps Fast Ethernet switching ports and one
10Mbps RJ11 symmetric Ethernet over VDSL port
(symmetry means 10Mbps upstream and 10Mbps
downstream data rate). it is ideal for signal conversion by
transmitting the Ethernet data from the standard twisted
pair cable to the telephone cable and extending the
distance.
The Ethernet over VDSL combines the well proven
Ethernet and VDSL technology to transmit the Ethernet
format data by using VDSL signaling over the most
widespread telephone wires and has no impact to current
voice service. Therefore, it is very good for Internet building
phone line network because every room or house could
use the existing phone line to transmit data to the Internet
and the whole building could share the Internet line to the
wide area network with minimum cost.
With much enough bandwidth, the 10Mbps symmetric
capability enables many multi-media services on local
Internet come true, like VOD (Video On Demand), Internet
caching server, distance education, … and so on.
In one community or hotel, we just need to install one local
server then the multi-media services will be localized that
is people do not need to access the services through
Internet but using local area network with better bandwidth
and efficiency. Meanwhile, this kind of infrastructure will
minimize the burden on the Internet.
The converter is plug-n-play without any software to
configure and also fully compliant with all kinds of network
protocols. Moreover, the rich diagnostic LEDs on the
front-panel provide the operating status of individual port
and the whole system. There are two models of the
converters, one is used for client side and the other is

3. INSTALLING AND USING ETHERNET
OVER VDSL CONVERTER
3.1 Install the Ethernet Over VDSL Converter
The Converter does not require any software
configuration. Users can immediately use any feature of
this product simply by attached the cables and plug power
on. There is some key limitation on the Ethernet over VDSL
converter. Please check the following items:
‧
‧
The device is used for point-to-point connection only and
allow data and voice work on the same telephone lines.
Two RJ-11 connectors for VDSL port. One for voice device
connection (like telephone) and the other one for network
link connection.
‧
Depending on the quality of telephone line, the maximum
distance of one VDSL segment is 1.2km (4000ft) with AWG
26 telephone wires. The distance will change by the quality
of telephone wires. We got some data as following table.
Phone line wire (diameter) Distance
AWG 26 (0.40 mm)
AWG 24 (0.51 mm)
AWG 22 (0.64 mm)
1.2km
1.3km
1.5km
Therefore, this device is an ideal client access unit for the
applications of apartment, hotel, campus and hospitality.
Integration with the Internet access concentrator, the total
infrastructure could be a perfect solution for multi-media
local Internet. This structure could support many
multi-media applications, like VOD (Video on Demand),
Distant education, Internet caching server, … and so on.

Therefore, most of the traffic will be limited on the local
phone line network instead of flooding to the Internet.
Another application for the converter is used for LAN to
LAN extension through the normal telephone line.
3.2 LAN to LAN connection
Two sets of the converters could be used to link two local
Area networks that are located in different areas. Through
the normal telephone line, it could setup a 10Mbps
symmetric backbone, but one converter must be Master
and the other one is “Slave”.
3.3 Connect to Multi-Port Master
In order, to built up a local internet in apartment, hotel, campus
and hospitality environment.
The Internet Access Concentrators need to be placed In the
wiring center( MDF room) and connect to the telephone line
system, on the other hand, need to install a “Slave” converter
on the individual client side and connect to the Multi Port
Master through the telephone lines.
Multi-Port Master
When deciding where to put the converter then you must
ensure:
ꢁ
It is accessible and cables can be connected easily.
Cabling is away from sources of electrical noise such
as radios, transmitters and power lines and
fluorescent lighting fixtures.

Air flow around the unit and through the vents in the
side of the case is not restricted (company
recommend that you provide a minimum of 25mm
inch clearance)
To prolong the operational life of your units:
ꢁ
ꢁ
Do not place objects on top of any unit or stack
Do not obstruct any vents at the sides of the case
3.4 Installing Network Cables
After placing the converter on the desktop, then we need to
know how to connect the device to network.
3.5 Station Connections with Telephone Wires
Connect the network adapters in stations to the converter’s
10/100Mbps switching ports through category 3, 4 or 5
UTP cables. There are two RJ11 phone jacks, one for
telephone set connection and the other one is used for
phone line network connection. If you have telephone wall
jacks at home then all you need to do is connecting the
RJ11 network port to the wall jack through telephone wires.
Warning !
Connection of the RJ-45 connector from an RJ-11 to TNV
circuits can cause permanent damage to the device.

4. SWITCH OPERATION
4.1 MAC Address Table and Learning
The converter built in with a MAC address table that is
composed of many entries. Each entry is used to store the
address information of network nodes on the network,
including MAC address, port ID, etc. The information is the
most important base to do packet filtering and forwarding.
When one packet comes in from any port, the switch will
learn the source address, port ID, and the other related
information in address table. Therefore, the content of the
MAC table will update dynamically.
4.2 Filtering and Forwarding
When one packet comes in from any port of the switch, it
will check the destination address besides the source
address learning. The switch will look up the address table
for the destination address. If not found, this packet will be
forwarded to all the other ports except the source port. If
found and the destination address is located at different
port from this packet comes in, the packet will be
forwarded to the port where this destination address is
located according to the information of address table. But,
if the destination address is located at the same port as
this packet comes in then this packet will be filtered.
4.3 Store and Forward
Store-and-forward is one kind of packet-forwarding
methodology. As a store-and-forward switch, it will store the
complete packet in the internal buffer and do the complete error
checking before transmitting to the network. Therefore, no error
packets will disturb the network. It is the best choice when a
network needs efficiency and stability.
