General Description
VDSLloop extender (VER) can extend the coverage of VDSLlines. It will provide systems
with higher performance-to-cost ratio, improve equipment utilization rate and optimize the
network. This product will allow you to double the number of subscribers with the bit-rate you
desire while offering more consistent high bandwidth services to your existing customers.
The VDSLLoop Extender is an active element installed in the outside loop plant. It operates
as an amplifier and equalizes the signal.
VDSLloop extender box and the extender card are as below:
VER-1P box: One box for 1 VER-1P embedded.
VER-1P: One port VDSLloop extender for one VDSLsubscriber can be inserted into the
extender’s box easily.
Benefits
Comprehensive over-voltage protection.
Low power consumption and more environmentally friendly

3.3. Switches setting
There are 2 switches, one is labeled “Up”, another is labeled “Down”. They are all two-bits
switch, explained as fellows.
When L2 is longer, both bits of “Up” switch should be set to “high” position, and when L2
shorter, both bits be set to “low” position. The demarcation point is about 1.0 Km for AWG 26
cable, or about 1.2 Km for AWG 24 cable.
When L1 is longer, both bits of “Down” switch should be set to “high” position, and when L1
shorter, both bits be set to “low” position. The demarcation point is about 1.7 Km for AWG 26
cable, or about 2.1 Km for AWG 24 cable.
With real cable, considering the ageing, you can check which position (high or low) should be
set, for the two switches (Up or Down), by reading the line bit-rate on VDSL Modem, or on
DSLAM. High line bit-rate is available, by setting the “Up” switch and “Down” switch to their
respective right positions, two bits of any one switch must be on same position.

Installation Procedure
5.1 Unpack
Unpack equipment carefully, check for completeness against the purchase order. Notify the
supplier if items are missing.
Note: Save packing material. All equipment returned must be packed in the original
packing material.
Inspect equipment for shipping damage, including bent or loose hardware, and broken
connectors. If equipment was damaged in transit, contact the supplier.
5.2 Install the remote power supply
Generally, the Power Supply is installed at CO side. The type of power supply ordered should
be right, either AC110V /AC220V or DC48V.
The Power supply also can be installed in the CPE or near the extender.
One Spare copper pair is needed for deliver power to VER-1P.
Before installation, the DC 48V or AC110V~AC220V power supply should be grounded
reliably.
DC 48V Power input is non-polarity.
The output of DC116V is non-polarity.
Attention:
1. Ground terminal should be grounded reliably. Copper-core wire with no less than 2.5mm2
section area is required as ground wire.
2. Remote power supply should not be turned on until the extenderinstallation is finished.
3. When the power supply wire is active, do not touch both two wires of the twist pair
simultaneously.
5.3 Install the VER
Fix the VER-1P box in the junction cabinet or near about at the supplied point. Ground the box
through the grounding screw in the bottom outside the box.
Attention: Copper-core wire with no less than 2.5mm2section area is required as ground

wire. One end of the wire should connect to loop extender’s ground terminal. The other
end of the wire should connect to a good ground point.
Connect the cable
VER-1P: Connect the power line with blue/white pair wire，CO signal line with orange/white,
CPE signal line with green/white pair wire.
Attention: The power supply should not be turn on until the extender installation is
finished.
Power on
Power on after confirming that all the twist-pair cables are connected correctly and box is
securely installed.
Setting on DSLAM
Objective of VER’ s design is to get higher up-stream bit-rites within US0(f1=276 Hz). So it is
important to set on DSLAM to get higher us bites by EU-64.

High noise on telephone
No splitter used at CPE side
Add splitter
Cable is connected to ground or the
insulation is not good caused by men
during the construction process
Check the cables
Cable is too near to some electric
equipments with strong magnetic
field, such as high power sounder,
rectifier and high power motor
Make cable far from the strong
magnetic field
VDSL is not ok, but the
status LED is on, and
telephone ok
Cable L1 and cable L2 are connected
on wrong side
Correct the connection of cable L1 and
cable L2
splitter is connected on wrong
terminal ports
Correct the connection of terminal
ports:
“Line” to cable L2；
“Phone”to telephone set；
“Modem”to VDSL modem
Not suitable installation site
Correct the installation site according
to table 3,table 4
Too long parallel lines
Replace parallel lines with twist pair
wires
Affection of computer hardware
failures, system failures and virus
Check computer or take with PC,
testers and so on to deal with
The parallel cable at CPE side is too
long or the connector is oxidation
It is better to change the parallel cable
to copper twist cable
The cable to CPE side is connected
with too many connectors
Avoid exposed connectors, use good
quality cable instead scattered
connectors
