1. General Description
The ADSL Loop Extender expands the coverage of ADSL lines. It will provide systems with a
higher performance-to-cost ratio, improve equipment utilization rates, and optimize the network.
This product will allow you to double the number of subscribers that you can reach while
offering a more consistent high bandwidth service to your existing customers.
The ADSL Loop Extender is an active element installed in the outside loop plant. It operates
as an amplifier and equalizes the signal.
The new generations of line powered ADSL Loop Extenders consist of an enclosure and card
system designed to offer a modular deployment option. The parts list is detailed below:
AER800-24P Box: A Box for 24 AER800-C1P cards and 3 AER800-PWR cards, which
are divided into 3 independent sub-systems.
AER800-C1P: A one port ADSL Loop Extender designed to be inserted into the
backplane of the AER800-24P enclosure.
AER800-PWR: One port Power Supply, which can power 1~8 AER800-C1P cards, and
can be inserted into the AER800-24P.
Benefits

5. Installation Procedure
5.1 Unpack
When unpacking the equipment, be sure to check the contents of the packaging for
completeness against your purchase order. Notify your supplier immediately if any items are
missing.
Note: Please save packing material. All equipment returned must be packed in the original
packing material.
Be sure to inspect the equipment for shipping damage, including bent or loose hardware, and
broken connectors. If the equipment appears to have been damaged in transit, please contact
your supplier.
5.2 Install the Power Supply
(1) Generally, the Power Supply is installed at the CO. Make sure the type of power supply you
ordered, AC85V~AC265V or DC48V is correct for your source voltage.
(2) Before installation, the DC 48V or AC85V~AC265V power supply must be reliably
grounded.
(3) The power supply can also be installed in the CPE or near the ALE, if CO installation is not

permission of Widearea.
feasible.
(4) If the ADSL Loop Extender is installed in a remote location without local power available,
an additional copper pair (L3 as shown in Fig. 1) is required for power. The supply voltage
will pass through the power converter and feed to this additional pair.
(5) The supplied accessories include a power cord for DC -48V. Connect it to the DC -48V power
source. Please connect the cord according to the polarization indicated.
(6) Remove about 10mm of insulation and insert the wire end into the connector matched with
the outlet and screw it down. Then insert the connector into the outlet. After that, connect
the signal cable, the signal cable is polarity independent.
Attention: 1.Please connect the ground terminal to reliable a ground. Copper-core wire
with no less than 2.5mm2(13 AWG) diameter is required as ground wire.
2. Power supply should NOT be turned on until the ALE installation is
finished.
3. When the power supply wire is active, do NOT operate the A and B wire of
the supply pair simultaneously. The A and B wire should be isolated.
5.3 Install the ADSL Loop Extender
(1) Install the AER800-24P Enclosure in the junction cabinet. Ground the Enclosure through the
grounding screw located on the bottom outside the Box.
Attention: Copper-core wire with no less than 2.5mm2(13 AWG) diameter 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 reliable grounding point.
(2) Insert the power card AER800-PWR into the AER800-24P Box.
(3) Insert the Extender card AER800-C1P into the AER800-24P Box.
(4) Connect the cable according to the connection diagram.
Connect the power pair into the AER800-PWR card.
Connect the signal cable to the terminal area, the cable from the DSLAM connects to the
“CO”terminal, and the cable from the modem connects to the “CPE”terminal.
Attention: The Power Supply should NOT be turned on until the Extender installation is

permission of Widearea.
finished.
(5) Power on: after confirming that all the twisted-pair cables are connected correctly and the
Enclosure is securely installed, Then turn on the Extender card, please make sure Extender
card Power Switch is set to ON. After powering on the system the ADSL Loop Extender will
work within 10 seconds.

Correct the cable connection, or
check whether the distance between
the DSLAM, Extender, and Modem
is within recommended values.
L1 or L2 is too short.
Check that loop extender placement
meets engineering requirements.
SNR Margin is too
high.
Reduce SNR Margin setting on the
DSLAM until a connection is made.
We suggest using SNR Margin < 10.

Testing with SNR margin = 1 can
provide useful hints during
troubleshooting.
There is noise on the user’s
telephone line.
CO/CPE cable is
connected to ground
or the wire insulation
is faulty.
Check the cables.
Possible
electromagnetic
interference.
Check to ensure the extender is not
located near any high voltage
equipment.
Internet is slow, frequent
disconnects.
Possible PC issues,
virus, hardware
malfunction, etc.
Verify issue with test set or a known
good piece of hardware. Check
statistics on modem and DSLAM.
Parallel open wire at
CPE is too long or
the connector is
rusted.
Change the parallel cable to copper
twisted-pair.
The CPE side cable
has too many
connectors.
Avoid exposed connectors, use good
quality cable.
SNR Margin too low.
Increase the SNR margin setting in
the DSLAM to 6 or more.
Bit Error Rate too
High.
Increase SNR Margin setting in the
DSLAM.
Data profile is too
high for this circuit.
Lower the minimum data rate in the
DSLAM.
