4.Installation Steps
The AER800-4P is deployed with AEC-B1P. Commonly, the ADSL Loop
Extender is installed in the junction cabinet, or on the pole at the middle locality.
The Power Supply is installed either at CO or at CPE with remote supply. The
details about ADSL Loop Extender and Power Supply installation are as follows:

Figure 4 A or B way remote power supply
Generally , the Power Supply can be installed either 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 two Spare copper pairs are needed for deliver the
output voltage to ADSL Loop Extender.
Connect tails
Figure5 AEC-B1P Connector Wiring Diagram
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.
○
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 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.
Figure 6 AER800-1P/2P installing Outdoors
Just as the structure above, the ADSL Loop Extender is fixed in the wire rope or
in the wall with a fixity.
②Connect the cables
Wiring sockets on front panel for DSLAM and Modem side signal
wiring and power supply wiring. Metal bolt on front panel for ground
connection.

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 compare to the Table5
and Table6 to find out the problems.
Table 6 AEC-B1P 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

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
