DC Power Jack
The VC-234G/VC-231G requires 5V DC, 2A power input,
which conforms to the bundled AC adapter. Should you have
the issue of power connection, please contact your local sales
representative.
Note
The device is a power-required device, meaning it
will not work till it is powered. If your networks
should be 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.
Note
In some areas, installing a surge suppression
device may also help to protect your Ethernet
over VDSL2 Bridge from being damaged by
unregulated surge or current to the Ethernet over
VDSL2 Bridge or the power adapter.
DIP Switch
The Ethernet over VDSL2 Bridge 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.

13
DIP-1 DIP-2 DIP-3 DIP-4
Mode Transmission Band Prole SNR Margin
OFF CO G.INP Asymmetric 12dB
ON (default) CPE Interleave Symmetric 8dB
DIP-1: Mode (CO/CPE)
CO
(Central
Ofce)
The Master device mode, usually the CO
device, is 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, is 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 or other
network devices.
Note
When the VDSL2 Bridge operates in CPE mode,
DIP switches 2, 3, and 4 are without function.
DIP-2: Transmission (G. INP and Interleave mode)
G. INP Method of protection against bursts from other
devices or lines to impact your xDSL line.
Interleave
Method of error correction used on xDSL
line. Interleave requires additional latency to
improve resilience to burst of error.

14
 DIP-3: Band Prole (Asymmetric/Symmetric)
Asymmetric
Asymmetric mode provides more bandwidth
than the other side.
This mode provides the highest bandwidth in
short range.
Symmetric
With G.997 band plan supported, symmetric
mode can provide almost the same rate of
downstream and upstream.
DIP-4: SNR (Signal Noise Ratio) Margin
When the SNR margin is selected, the system provides
12dB/8dB SNR margin for across all usable loop lengths. Better
channel noise protection is made with the higher SNR margin.
Note
By default, the four DIP switches, set at the
“ON” position, are operated as “CPE”. For oper-
ating as “CO”, please turn DIP 1 switch to the
“OFF” position. Then adjust other DIP switches
accordingly to fulfill different network application
demands.
Note
Please power off the VDSL2 Bridge before
making any transmission mode adjustment.

15
3.3 Power Information
The power jack of VC-231G and VC-234G measures 2.5mm in
the central post and requires +5VDC power input. It conforms
to the bundled AC-DC adapter and Planet’s Media Chassis.
Should you have the issue of power connection, please contact
your local sales representative.
Please keep the AC-DC adapter as a spare part when your
VC-231G is installed to a Media Chassis.
2.5mm DC Receptacle 2.5mm
+5V for each slot
DC receptacle is 2.5mm wide that conforms to and
matches the VDSL2 Converter 2.5mm DC jack’s central
post. Do not install any improper unit, model of the VDSL2
Bridge.

4.Connecting And Using The VDSL2 Bridge
The Ethernet to VDSL2 Bridge 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 VDSL2 Bridge. Please check the
following items:
¾The device can be used for Point-to-Point (one CO device
to one CPE device) connection or Point-to-Multipoint (one
multi-port CO device to multi CPE devices) and allows data
and voice work on the same telephone lines.
¾The VC-231G provides only one RJ11 connector for VDSL2
port to build VDSL2 connection. For voice device connection,
there is an additional splitter from VC-231G packages is an
idea choice.
¾The VC-234G provides two RJ11 connectors for VDSL2 port.
One for voice device connection (like telephone) and the
other one for VDSL2 network link connection.
¾Depending on the quality of telephone line, the maximum
distance of one VDSL2 segment is 1.4km (4593ft) with AWG
24 telephone wires. The distance could vary on the quality of
telephone wires.

4.1 Point-to-Point Application -- LAN to LAN
Connection
Two sets of the VDSL2 Bridge could be used to link two local
Area networks that are located in a different place. Through
the normal telephone line, it could be set up a 190/190Mbps
(VC-234G, G.INP, sym) symmetric backbone, but one VDSL2
Bridge must be Master (CO mode) and the other one is Slave
(CPE mode).

4. Power LED will illuminate.
5. Connect VDSL line from another VDSL device to RJ11 VDSL
port of the VC-234G/VC-231G.
6. VDSL LNK LED will blink to illuminate at both VDSL2
bridges.
7. Connect telephone to the RJ11 Phone port of the VC-234G/
VC-231G.
8. Connect VC-234G/VC-231G Ethernet LAN port to other
network device via regular Cat.5 UTP cable.
4.2 Point-to-Multipoint Application -- Connect to IP
DSLAM
To build a local Internet in apartments, hotels and campuses
and hospitality environments, it requires:
The multi-port VDSL2 IP DSLAM or VDSL2 switch (for example,
PLAMET VDL-2420M and VC-820M) operates as a CO Master
and needs to be placed in the wiring center (MDF room) and
connect to the telephone line system.
On the other hand, it needs to install one or many CPE Slaves
(VC-231G or VC-234G VDSL Bridge) on the individual client side
and connect to the multi-port Master through the telephone
lines.
