3.4 Mode 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 Channel Prole SNR
OFF CO Interleave 17A 9dB
ON (default) CPE Fast 30A 6dB

11
DIP-1: Mode (CO/CPE)
CO (Central
O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 oce, home or remote
side as the long reach data receiver. The CPE
can be connecting to the PC, IP Camera or
Wireless Access Point or other network devices.
Note
When the Ethernet Over VDSL2 Bridge operates in
CPE mode, DIP switch 2, 3, 4 have no function.
DIP-2: Channel (Fast and Interleave mode)
Fast Fast mode guarantees a minimum end-to-end
latency less than 1 ms.
Interleave
Interleaved mode provides impulse noises
protection for any impulse noise with a duration
less than 250 us. Interleaved mode has a
maximum end to end latency of 10m sec.

12
DIP-3: Prole (17a/30a)
User has the ability to select prole
30A
When 30a is selected that provides better
downstream/upstream performance in short
distance.
17A When 17a is selected that provide longer
distance link capability.
DIP-4: SNR (9dB/6dB)Target SNR (Signal Noise Ratio) Margin
When SNR margin is selected, the system provides 9 dB/6 dB
SNR margin for across all usable loop length.
Note
1. By default, the four DIP switch at “ON” posi-
tion that will operate as “CPE”. For operate as
“CO”, please adjust the DIP 1 switch as “OFF”
position. Then adjust other DIP switch accord-
ingly to fulfill different network application
demand.
2. Please power off the Ethernet over VDSL2
Bridge, before making any transmission mode
adjustment.

3.5 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-231 is installed to a media chassis.
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 over VDSL2 Bridge does not require any software
conguration. Users can immediately use any feature of this
product simply by attaching the cables and plug power on.
There is some key limitation on the Ethernet over VDSL2
Bridge. Please check the following items:
¾The device is used for Point-to-Point connection only
(Master device to Slave device) and allows data and voice
work on the same telephone lines.
¾VC-231 provides one RJ11 connector for VDSL port and
the port can build VDSL2 connection easily. For voice device
connection, the additional splitter together with VC-231
package is an ideal choice.

¾Depending on the quality of telephone line, the maximum
distance of one VDSL 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 Ethernet over VDSL2 Bridges could be used
to link two local Area networks that are located in a dierent
place. Through the normal telephone line, it could set up a
100/100Mbps symmetric backbone, but one Ethernet over
VDSL2 Bridge must be Master (CO mode) and the other one is
Slave (CPE mode).

1. [LAN1] Set the VDSL2 Bridge at LAN 1 to be CO mode from
the DIP switch.
2. [LAN2] Set the VDSL2 Bridge at LAN 2 to be CPE mode
from the DIP switch.
3. Power on the VDSL2 Bridge CO and CPE at both sides by
connecting its power source.
4. Power LED will illuminate.
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-231/
VC-234.

4.2 Point-to-Multipoint Application -- Connect to IP
DSLAM
To build a local Internet in apartment, hotel and campus and
hospitality environments, it requires:
¾The 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.
¾On the other hand, it needs to install a CPE Slave (VC-231/
VC-234 VDSL2 Bridge) on the individual client side and
connect to the Multi-port Master through the telephone lines.

Bridge.
8. Connect the VDSL2 Bridge Ethernet LAN port to other
network device via regular Cat.5 UTP cable.
When deciding where to put the converter and/or prolong the
operational life of the bridge, please also refer to the following
points:
¾It is accessible and cables can be connected easily.
¾Cabling is away from sources of electrical noise such as
radios, transmitters, motors, power lines and uorescent
lighting xtures.
¾Do not place objects on top of any unit or stack.
¾Water or moisture cannot enter the VDSL2 Bridge.
¾Air ow around the unit and through the vents in the side of
the case is not restricted (we recommend that you provide a
minimum of 25mm clearance).

4.3 Chassis Installation and Rack Mounting (VC-231)
To install the Ethernet over VDSL2 Bridge in a 10-inch or
19-inch Converter Chassis with standard rack, follow the
instructions described below.
Step 1: Place your VDSL2 Bridge on a hard at surface, with
the front panel positioned towards your front side.
Step 2: Carefully slide in the module until it is fully and rmly
tted into the slot of the converter chassis.
Step 3: Attach a rack-mount bracket to each side of the
Converter Chassis with supplied screws attached to the
package.
Step 4: After the brackets are attached to the Converter
Chassis, use suitable screws to securely attach the
brackets to the rack.
Step 5: Connect one end of the power cable to the 10-inch or
19-inch Converter Chassis.
Step 6: Connect the power plug of the power cable to a
standard wall outlet, and then power on the 10-inch or
19-inch Converter Chassis. The PWR LED should be lit.
Caution
You must use the screws supplied with the
mounting brackets. Damage caused to the parts
by using incorrect screws would invalidate your
warranty.
