If the loop resistance between Extender and Modem is lower than the demand value, the
LA800 which you could choose and buy from our company can be added to increase loop
resistance. The option LA800 is to be installed between splitter and Modem when used on a
line with analog voice. Here is the application of LA800 below:

4.Installation Steps
The AER800-8P is deployed with 2 AEC-B1PH or AEC-C2P V5.0 plugged into
AEC-RACK.
Note: The type of Power Supply is your choice when you order the product. The
installation of AEC-C2P follow the manual of AEC-C2P.
Commonly, the ADSL Loop Extender is installed in the junction cabinet, or one the wire
rope, or on the pole at the middle locality. The Power Supply can be installed either at CO or
at CPE with remote supply. The details about ADSL Loop Extender and Power Supply
installation are as follows:
4.1 Install the Power Supply(AEC-B1PH) for ADSL Loop Extender
1) the actual lines connecting of equipment
Figure 4 A or B way of ADSL Loop Extender with remote power supply
Generally , the Power Supply can be installed either at CO or at CPE with remote supply,
just as the Fig5. In the way of A or B, AC110V,AC220V or DC48V can be selected, make
sure the type of Power Supply you ordered. Two Spare copper pairs are needed for deliver
the output voltage to ADSL Loop Extender.

Three-core power cord without plug: used for DC48V power input, no polarity.
Three-core power cord with plug: used for AC110-240V power input.
Power output: 155V power output cable which is already connected to the terminal in wiring
box by factory.
Protection ground: Black protection ground wire should be connected to the protection
ground terminals.

Connect the power supply tail(L3)
There is an additional copper pair which power the ADSL Loop Extender. Now, the supply
voltage from wiring box will go through an additional copper pair and into the ADSL Loop
Extender directly. The detail way is as follows:
The Power Supply is installed in the cabinet, and the power supply cable connect with a
separate copper twist pair, at the placement of ADSL Loop Extender, the ADSL Loop
Extender’ blue/white lines connect with the same copper wire pair. For one thing, the cable
pair must be free of DC type faults. All shorts, grounds, cross, battery-crosses, and open
cable pairs must be identified and repaired.
② Ground
Connect the Power Supply equipment’s ground to CO’s grounding terminal directly.
③ Connect power cord
The supplied accessories include power cord for AC 110V、 AC220V or DC 48V. Connect
it to the AC 110V、AC220V or DC 48V power source with good connection. To easy the
installation, DC power source connection is no polarized.
After power supply is connected, the power indicator should be solid on. Flashing indicator
indicates short circuits or over-current alarm condition.
Attention: ADSL Loop Extender’s Power Supply should NOT be turned on until the

Extender installation is finished.
4.2 Install the ADSL Loop Extender
① ADSL Loop Extender can be placed in the junction cabinet if there is inner room
available. Or ADSL Loop Extender can be mounted in the box through supplied mounting
brackets.
Attention: Copper-core wire with no less than 1.5mm2 section 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 grounding point.

Unlock the box of AER800-8P with the hexagonal wrench. Wiring sockets on front panel for
DSLAM and Modem side signal wiring and power supply wiring. Metal bolt on front panel
for ground connection. The detailed connection follows the picture on silk-screen.

After power on, the “STATUS” LED should be lightened in a few seconds and remain on
during normal system operation. Lock the box with the hexagonal wrench, pay attention to
wrench clockwise rotation to undersurface of the box into parallel lines, then stop rotation.
③ Power up
After confirming that all the twist-pair cables are connected correctly and enclosure is
securely installed, power up the system. The ADSL Loop Extender will work in 20 seconds
after power is supplied stead.
Attention:
a) “A” and “B” represent A and B wire of the twist-pair. No polarity.
b) Before power up the system, please make sure all the connections are correct.
c) When the power supply wire is active, do NOT operate the A and B wire of the
supply pair simultaneously. The A wire and B wire should be isolated.
5.Troubleshooting
If the ADSL Loop Extender can’t work well, please follow the Table5 and Table6 to
find out the problems.
