1.2 Introduction to Ethernet over VDSL2 Bridge
PLANET’s state-of-the-art Ethernet-over-VDSL2 products are
based on two core networking technologies: Ethernet and
VDSL2 (Very-high-data-rate Digital Subscriber Line 2). This
technology offers the absolute fastest possible data transmission
speeds over existing copper telephone lines without the need for
rewiring.
The VC-201A / VC-204 Ethernet Over VDSL2 Converter has a
switching architecture with RJ-45 10/100Mbps Ethernet port
and one symmetric Ethernet over VDSL port (symmetry means
upstream and downstream rate are the same or similar) – the
VDSL port can be RJ-11 connectors. The VC-201A / VC-204 can
be set to CO mode or CPE mode via a DIP switch. When the
VC-20X-CO is used to connect to the other VC-20X-CPE as a
standalone pair, up to 100/55Mbps asymmetric data rate within
200m and up to 25/4Mbps asymmetric data rate at 1.6km.
This capability is ideal for use as an Ethernet extender for your
existing Ethernet network.

PLANET’s VDSL2 Converter solution provides a much cheaper
replacement and smooth migration for existing Long Reach
Ethernet (LRE) networks.
The cable specications of the connection are listed as following:
n10BASE-T, Category 3, 4 or 5 UTP
n100BASE-TX, Category 5 UTP
nEthernet over VDSL, Twisted-pair telephone wires
The two drawings listed below are typical application for the
Ethernet Over VDSL2 Converter.
Note
Slave device (CPE) must connect to Master device
(CO) through the telephone wire. Slave cannot
connect to Slave and Master cannot connect to
Master. To define the VC-201A / VC-204 to CO or
CPE, please refer to section 2.2.1 for more detail.

2. Hardware Description
The VC-201A / VC-204 provides 2 RJ-11 ports for voice
connection (like telephone) and for network line connection.
The VC-201A provide 1 RJ-45 ports and VC-204 provide 4 RJ-45
ports for two different running speed –10Mbps, 100Mbps, in the
same bridge and automatically distinguish the speed of incoming
connection.
This section describes the hardware features of the Ethernet
Over VDSL2 Converter. 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.

2.2.1 MODE DIP Switch
The Ethernet Over VDSL2 Converter provides 4 selective
transmission modes. 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 setting, bandwidth and distance
extensibility tested for AWG 24 (0.5mm) twisted-pair without
noise and cross talk.

17
DIP-1 DIP-2 DIP-3 DIP-4
Mode Channel Band Plan SNR
OFF CO Interleave Symm 9dB
ON (default) CPE Fast Asymm 6dB
CO / CPE
u CO (Central Ofce) – the Master device mode, usually
the CO device will be located at the data center of ISP or
enterprise to link to the backbone.
u CPE (Customer Premises Equipment) – the Slave device
mode, usually the CPE device will be located at branch
ofce, home or remote side as the long reach data receiver.
The CPE can be connect to the PC, IP Camera or Wireless
Access Point and etc network devices.
Note
When the Ethernet Over VDSL2 Converter operate
at CPE mode, the DIP switch 2,3,4 is no function.
Fast and Interleave mode
u Fast mode guarantees a minimum end to end latency less
than 1 ms.
u Interleaved mode provides impulse noises protection for
any impulse noise with a duration less than 250 us. Inter-
leaved mode has a maximum end to end latency of 10m
sec.
Band Plan
uUser has the ability to select Band Plan. When Symmetric
is selected that provides better downstream performance,
when Asymmetric is selected that provides better upstream
performance. Refer to table above for details.

Target SNR (Signal Noise Ratio) Margin
u When xed SNR margin is selected, the system will main-
tain the SNR margin at 9 dB across all usable loop length.
Note
By default setting, the four DIP switch at “ON”
position and operate as “CPE”. For operate as
“CO”, please adjust the DIP 1 switch as “OFF”
position. Adjust other DIP switch setting to fill
different network application demand.
Please power off the Ethernet Over VDSL2 Converter, before
making any transmission mode adjustment.
2.2.2 DC power jack
VC-201A / VC-204 require 5V DC power input. It will conform
to the bundled AC adapter. Should you have the problem to
make the power connection, please contact your local sales
representative.
Note
1. The device is a power-required device, it
means, it will not work till it is powered. If
your networks should active all the time,
please consider using UPS (Uninterrupted
Power Supply) for your device. It will prevent
you from network data loss or network down-
time.
2. In some area, installing a surge suppression
device may also help to protect your Ethernet
Over VDSL2 Converter from being damaged by
unregulated surge or current to the Ethernet
Over VDSL2 Converter or the power adapter.

3. Installing and Using VDSL Converter
3.1 Install the Ethernet Over VDSL2 Converter
The Ethernet Over VDSL2 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 VDSL2
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 lines.
VC-201A / VC-204 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 2.0km (6560ft) with AWG
24 telephone wires.
The distance will change by the quality of telephone wires.

3.1.1 VC-201A / VC-204 LAN to LAN connection
Two sets of the Ethernet Over VDSL2 Converters could be used
to link two local Area networks that are located in different
place. Through the normal telephone line, it could setup a
100/55Mbps asymmetric backbone, but one Ethernet Over
VDSL2 Converter must be Master (CO mode) and the other one
is Slave (CPE mode).

In order, to built up a local Internet in apartment, hotel, campus
and hospitality environment.
The Multi-port Master (for example, VC-810S VDSL2 Switch)
need to be placed in the wiring center (MDF room) and connect
