DC Power Jack
The VC-231GP requires 54V DC, 0.74A power input, which
conforms to the bundled AC-DC 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.

11
Note
In some areas, installing a surge suppression
device may also help to protect your VC-231GP
from being damaged by unregulated surge or
current to the VC-231GP or the power adapter.
¾DIP Switch
The VC-231GP 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
¾DIP-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.

12
Note
When the VC-231GP in CPE mode, DIP switches 2,
3, and 4 are without function.
¾DIP-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.
¾DIP-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.
¾DIP-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 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.

13
Note
Please power off the VC-231GP before making
any transmission mode adjustment.
3.3 Power Information
The central posts of the VC-231GP’s power jacks measure
2.5mm wide that require +54VDC power input. They conform to
the bundled AC-DC adapter. Should you have the issue of power
connection, please contact your local sales representative.
2.1mm
Width of DC Receptacle: 2.1mm
+54V for DC jack
DC receptacle is 2.1mm wide that matches the central post,
measuring 2.1mm wide, of the VC-231GP’s DC jack. Do not
install any improper unit.

4. Connecting And Using The VDSL2 Bridge
The VC-231GP 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 VC-231GP. Please check the following items:
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 to work on the same telephone lines.
The VC-231GP provides only one RJ11 connector for VDSL2
port to build VDSL2 connection. For voice device connec-
tion, there is an additional splitter from the package of the
VC-231GP, which is an ideal choice.
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.

4.1 Point-to-Point Application - LAN to LAN
Connection
Two sets of the VC-231G/VC-231GP 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
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).

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 VDL-2420M and 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-231GP) on the individual client side and
connect to the multi-port Master through the telephone lines.
