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 AER800-4P is deployed with AEC-B1PH. Commonly, the ADSL Loop Extender is
installed in the junction cabinet, or on the pole at the middle locality. The Power Supply is
installed at CO 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

Figure 4 A or B way of ADSL Loop Extender with remote power
supply
Generally , the Power Supply can be installed at CO or at CPE with remote supply, just as
the follow Fig5. In the way of A or B, AC110V,AC220V or DC48V can be selected, and one
Spare copper pair are needed for deliver the output voltage to ADSL Loop Extender.
Connect tails
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

Protection ground: Black protection ground wire should be connected to the protection
ground terminals.
○
1Connect the power supply tail(L3)
There is an additional copper pair which powering 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 an
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.
②Ground
Connect the Power Supply equipment’s ground to CO’s grounding terminal directly.
③Connect 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
ADSL Loop Extender installation is finished.
4.2 Place the ADSL Loop Extender
①ADSL 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 2.5mm2 section area is required as
ground wire. One end of the wire should connect to ADSL Loop Extender’s ground
terminal. The other end of the wire should connect to a good grounding point.

After power on, the “STATUS”LED should be lightened in a few seconds and remain on
during normal system operation.
③Power 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.
Table 5 - AEC-B1PH Troubleshooting
Problem Description
Possible Reason
Suggested Resolution
Equipment does not work after
power-up. Status LED is OFF.
Power supply cable is
not correctly
connected.
Check power supply cable connection.

Power indicator flashes.
Power output
circuitry fails.
Check whether the connection is shorted. Or
check whether the connection between
Extender and Modem is OK.
Output is OK but the Extender
does not work.
Power output cable
connection is error or
short.
Correct the power output connection or check
cable. Or check whether the distance between
DSLAM, Extender, Modem is proper.

There is noise in user’s
telephone
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, selenium
rectifier and high power motor.
Make cable far from the
strong magnetic field.
Internet is slow, frequent
off-line problem
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.
