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.
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
Note
Note
using UPS (uninterrupted power supply) for your
device. It will prevent you from network data loss
or network downtime.
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.

The Master device mode, usually the CO
device, is located at the data center of ISP or
enterprise to link to the backbone.
The Slave device mode, usually the CPE
device, is located at branch ofce, 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.
When the VDSL2 Bridge operates in CPE mode,
DIP switches 2, 3, and 4 are without function.
Method of protection against bursts from other
devices or lines to impact your xDSL line.
Method of error correction used on xDSL
line. Interleave requires additional latency to
improve resilience to burst of error.

Note
Note
than the other side.
This mode provides the highest bandwidth in
short range.
With G.997 band plan supported, symmetric
mode can provide almost the same rate of
downstream and upstream.
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 other DIP switches
accordingly to fulfill different network application
demands.
Please power off the VDSL2 Bridge before
making any transmission mode adjustment.

4. Connecting And Using The VDSL2 Bridge
The Ethernet to VDSL2 Bridge does not require any software
conguration. 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:
¾ The 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.
¾ The 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.
¾ The 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.
¾ Depending 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.

1. Verify the length of the wire (not more than 1.4km)
connected between VC-231G and VC-234G. Please also try
to adjust the DIP switch or VC-231G/VC-234G to other SNR
mode.
2. Please note you must use one VC-231G/VC-234G in CO
mode and the other VC-231G/VC-234G in CPE mode to make
connection to each other work.
SYMPTOM:
TP LED does not light after cable is connected to the port.
CHECKPOINT:
1. Verify you are using the Cat.5 or better cable with RJ45
connector to connect to the port.
2. If your device (like LAN card) supports to auto-negotiation,
please try to manually set at a xed speed of your device to
solve this issue.
3. The Converter/Bridge and the connected device’s power are
on or not.
4. The port’s cable is rmly seated in its connectors in the
switch and in the associated device.
5. The connecting cable is good and with the correct type.
6. The connecting device, including any network adapter, is functional.

8. FAQ
Q1: What is VDSL2?
A1: VDSL2 (Very High-Bit-Rate Digital Subscriber Line 2),
G.993.2 is the newest and most advanced standard of
xDSL broadband wire line communications.
Designed to support the wide deployment of Triple Play
services such as voice, data, high denition television
(HDTV) and interactive gaming, VDSL2 enables opera-
tors and carrier to gradually, exibly, and cost efciently
upgrade the existing xDSL-infrastructure.
Q2: What is SNR and what’s the effect?
A2: In analog and digital communications, Signal-to-Noise
Ratio, often written as SNR, is a measure of signal strength
relative to background noise. The ratio is usually measured
in decibels (dB).
In digital communications, the SNR will probably cause a
reduction in data speed because of frequent errors that
require the source (transmitting) computer or terminal to
resend some packets of data. SNR measures the quality
of a transmission channel over a network channel. The
greater the ratio, the easier it is to identify and subsequently isolate and eliminate the source of noise.
Generally speaking, the higher SNR value gets, the better
the line quality gets, but performance is lower.
Q3: What is the best distance for VC-231G/VC-234G?
A3: In order to guarantee the stability and better quality of
network, we suggest the distance should not exceed 1.4
kilometer.

Q4: What is the best date rate for VC-231G/VC-234G?
A4: The best data rate of the VC-231G is up to
225Mbps/122Mbps (downstream / upstream) in asymmetric
mode and 191Mbps/161Mbps in symmetric mode over
a distance of 200 meters. The VC-234G provides a data
rate of up to 248Mbps/127Mbps (downstream/upstream)
in asymmetric mode and 192Mbps/190Mbps in symmetric
mode over a distance of 200 meters.
