to take adequate measures.
Energy Saving Note of the Device
This power required device does not support Standby mode
operation.
For energy saving, please remove the DC-plug or push the hardware
Power Switch to OFF position to disconnect the device from the
power circuit.
Without removing the DC-plug or switch off the device, the device
will still consume power from the power source. In the view of
Saving the Energy and reduce the unnecessary power consuming, it
is strongly suggested to power off or to remove the DC-plug for the
device if this device is not intended to be active.

1.2 Ethernet over VDSL2 Bridge Description
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 or coaxial cables
without the need for rewiring.
The VC-201A / VC-202A / VC-204 Ethernet Over VDSL2
Converter has a switching architecture with RJ-45 10/100Mbps
Ethernet port and one asymmetric or symmetric Ethernet over
VDSL port (Asymmetric means upstream and downstream
rate are not the same and Symmetric means upstream and
downstream rate are similar) – the VDSL port can be RJ-11
connector (VC-201A / VC-204) or BNC Connector (VC-202A). The
VC-201A / VC-202A / VC-204 can be set to Central Ofce (CO)
or Customer Premises Equipment (CPE) mode via a DIP switch.
When VC-20X-CO (VC-201A / VC-204 is connected with other
VC-20X-CPE (VC-201A / VC-204) device, the performance will

6
up to 100/55Mbps for asymmetric data rate within 200m and up
to 25/4Mbps for asymmetric data rate at 1.6km. The VC-202A
(BNC) performance is up to 100/65Mbps for asymmetric data
rate within 200m and up to 25/5Mbps for asymmetric data rate
at 3.0km. This capability is ideal for use as an Ethernet extender
for your existing Ethernet network.
PLANET VDSL2 Converter 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:
10Base-T, Category 3, 4 or 5 UTPl
100Base-TX, Category 5, 5e or 6 UTPl
Ethernet over VDSL2, Twisted-pair telephone wiresl
Ethernet over VDSL2, Coaxial cablel
The two drawings pictures are typical application for the Ethernet
over VDSL2 Converter.
Note
Slave device (CPE) must connect to Master device
(CO) through the telephone wire or coaxial cable.
It is not allow connecting like Master to Master or
Slave to Slave. To define the VC-201A / VC-202A /
VC-204 to CO or CPE, please refer to section 2.2.1
for more detail.

2.2.1 DIP Switch Mode
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.

18
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 / CPEn
• 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.
• 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 connected 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 Moden
• Fast mode guarantees a minimum end to end latency less
than 1 ms.
• Interleaved mode provides impulse noises protection with
a duration less than 250 us. Interleaved mode has a
maximum end to end latency of 10m sec.
Band Plann
• User can switch the Band Plan either Symmetric or Asym-
metric by their own. When Symmetric is selected that
provides better upstream performance, when Asymmetric
is selected that provides better downstream performance.
Refer to table above for details.

19
Target SNR (Signal Noise Ratio) Marginn
• 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 to “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-202A / VC-204 require 5V DC power input. It
will conform to the bundled AC adapter. If you have the issue
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 downtime.
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.Installation
3.1 Install 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:
VC-201A and VC-204:lThe device is used for Point-to-Point
connection only (Master device to Slave device) and has
equipped with 2 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 1.6km (5250ft) with AWG
24 telephone wires.
VC-202A:l1 BNC connector and supports 50 or 75 ohm cable.
Depending on the quality of coaxial cable, the maximum
distance of one VDSL segment is 3.0km (9842ft) with 5C
coaxial cable.
The distance will change by the quality of telephone wires and
coaxial cables.
3.1.1 VC-201A / VC-202A / 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).
