DC Power Jack
The VC-231G Series 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.

12
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.
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
Oce)
The Master device mode, usually the CO
device, is located at the data center of ISP or
enterprise to link to the backbone.

13
CPE
(Customer
Premises
Equipment)
The Slave device mode, usually the CPE
device, is located at branch o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 out of 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.
 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.

14
Note
By default, the four DIP switches, set at the “ON”
position, are operated as “CPE”. For operating
as “CO”, please turn DIP 1 Switch to the “OFF”
position. Then adjust the other DIP switches
accordingly to fulfill different network application
demands.
Note
Please power off the VDSL2 Bridge before
making any transmission mode adjustment.
3.3 Power Information
The central posts of the VDSL2 Bridge’s power jacks measure
2.5mm wide that require +5VDC power input. They conform 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 the
VC-231G/VC-231GF is installed to a media chassis.
2.5mm
Width of DC Receptacle: 2.5mm
+5V for each slot
DC receptacle is 2.5mm wide that matches the central
post, measuring 2.5mm wide, of the VDSL2 Bridge’s DC
jack. Do not install any improper unit.

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 putting the plug in the receptacle and turning
it 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 to work on the same telephone lines.
¾The VC-231G and VC-231GF provides only one RJ11
connector for VDSL2 port to build VDSL2 connection. For
voice device connection, there is an additional splitter from
the package of the VC-231G and VC-231GF, which is an ideal
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 dierent place. Through
the normal telephone line, it could be set up a 150/150Mbps
(G.INP, Sym, 8dB) symmetric backbone, but one VDSL2 Bridge
must be Master (CO mode) and the other one is Slave (CPE
mode).

5. Connect VDSL line from another VDSL device to RJ11 VDSL
port of the VDSL2 Bridge.
6. VDSL LNK LED will blink to illuminate at both VDSL2
bridges.
7. Connect telephone to the RJ11 Phone port of the VDSL2
Bridge.
8. Connect the VDSL2 Bridge Ethernet LAN port to other
network device via regular Cat.5 UTP cable for VC-231G/
VC-234G or optical ber cable for VC-231GF.
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, PLANET VC-820M) operates as a CO Master and
needs to be placed in the wiring center (MDF room) and
connects to the telephone line system.
On the other hand, it needs to install one or many CPE
Slaves (the VC-231G or VC-234G VDSL Bridge) on the
individual client side and connect to the multi-port Master
through the telephone lines.
