1.2 Introduction to Ethernet over VDSL Converter
The converter is a switching architecture with one RJ45 10/100Mbps Fast Ethernet ports
and one RJ11 symmetric Ethernet over VDSL port (symmetry means upstream and
downstream rate are the same or similar). 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 5/10/15 Mbps 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 efciency. Meanwhile, this kind of
infrastructure will minimize the burden on the Internet.
The converter is plug-n-play without any software to congure 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 central side. If you
want to setup one pair of converters for point-to-point connection then one set must be
slave (client) mode and the other one is master mode.
The cable specications of the connection are listed as following:

Note: Slave device must connect to Master device through the telephone
wire. Slave cannot connect to Slave and Master cannot connect to
Master. VC-102M works as Master device and VC-102S works as
Slave device.

Hardware Description
This product series provide 2 RJ-11 ports for voice connection (like telephone or ISDN)
and for network line connection.
This product series also provide 1 RJ-45 ports for two different running speed –10Mbps,
100Mbps, in the same converter and automatically distinguish the speed of incoming
connection.
This section describes the hardware features of these Converters. For easier control
of the converter, familiarize yourself with its display indicators, and ports. Front panel
illustrations in this chapter display the unit LED indicators. Before connecting any network
device to the converter, read this chapter carefully.
2.1 Front Panel and Real Panel
The units’ front panel provides a simple interface monitoring the converter.
VC-102M Front Panell
VC-102S Front Panel
2.1.1 LED indicators
The rich diagnostic LEDs on the front panel can provide the operating status of individual
port and whole system.
STATUS LED (VC-102M only)
The LED blinks periodically to show the converter is working normally. If the LED stays
green/dark that means the system is fail, you need to contact your agent or try to reboot
the converter.
PWR LED
This indicator lights green when the converter is receiving power; otherwise, it is off.

100 LED (Ethernet)
The RJ-45 port has a 100 LED. Steady green indicates that the port is operating at
100Mbps. If the LED is off, the link speed is 10Mbps.
LNK/ACT LED (Ethernet)
The RJ-45 port has a LNK/ACT LED. Steady green indicates that the port has good linkage
to its associated device. Flashing green indicates that the port is receiving or transmitting
data from/to its associated partner.
If the port is connected but the LNK/ACT LED is dark, check the following items:
1. The converter and the connected device’s power are on or not.
2. The port’s cable is firmly seated in its connectors in the switch and in the as-
sociated device.
3. The connecting cable is good and with correct type.
4. The connecting device, including any network adapter is functional.
FDX/COL LED (Ethernet)
A collision occurs when two stations within a collision domain attempt to transmit data at
the same time. Intermittent ashing amber of the collision LED is normal; the contending
adapters resolve each collision by means of a wait-then-retransmit algorithm. Frequency
of collisions is an indicator of heavy trafc on the network.
If the FDX/COL lights amber which means the port is under full-duplex operation or dark
for half-duplex mode.
LNK LED (VDSL)
If both ends of the VDSL devices are connected then the LED will blink for a while (in 10
seconds), this is the stage of speed auto-negotiation. After the negotiation process, the
LNK LED will stay green. If the LED blinks always, that means the link process is fail.
ACT LED (VDSL)
If there is any trafc transverses the port then the LED will light green. Otherwise, off
means no trafc on the network.
2.1.2 MODE DIP Switch (VC-102M only)
The converter provides 5 selective transmission modes that dened by predetermined
proles. By switching the transmission modes, you can obtain a best transmission mode
to suit with phone line quality or distance of connectivity. The following is the summary
table of transmission modes, bandwidth and distance extensibility tested for AWG 24
(0.5mm) twisted-pair without noise and cross talk.

Installing and Using VDSL Converter
3.1 Install the Ethernet Over VDSL Converter
The Converter does not require any software conguration. 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 (master device to slave
device) and allows data and voice work on the same telephone or ISDN 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 1.5km (5000ft) with AWG 24 telephone wires. The distance will
change by the quality of telephone wires.
3.1.1 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 an up to 15/17Mbps
asymmetric backbone, but one converter must be Master (VC-102M) and the other one
is Slave (VC-102S).
NOTE: VC-102M can be connected PLANET’s previous slave model, VC-101S.
The speed is also adjusted by the DIP-switch of VC-102M. VC-102S
can also be connected to previous master, VC-101M. The speed
depends on the firmware loaded on VC-101M. Please check the VC-
101M’s user’s manual for detail.
3.1.2 Connect to Multi-Port Master
In order, to built up a local Internet in apartment, hotel, campus and hospitality
environment.
The Multi-port Master (for example, VC-1602, VC-412 or Cisco LRE switch) 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 (VC-102S) converter on the individual client side and
connect to the Multi-port Master through the telephone lines.
When deciding where to put the converter then you must ensure:
n 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.
n Water or moisture can not enter the unit
