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 ADSL Loop Extender
(1) Fix the AER800-1/4/8PL Box in the junction cabinet or at the supplied mounted brackets.
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. Grounding reliability can only
ensure effective lightning-proof.
(2) Insert business card AER800-C1PL into AER800-4/8PL Box.
(3) Connect the cable
Connect the signal line to AER800-C1PL, the line from DSLAM to the “CO”terminal, the line
linked to the modem to the “CPE”terminal. After the CO side twisted pair is connected, the
“STATUS”LED should be lightened.
(4) After confirming that all the twist-pair cables are connected correctly and Box is securely
installed, the ADSL Loop Extender will work within 10 seconds after power is supplied steadily.
Attention:
“A” and “B” represent A and B wire of the twist-pair. No polarity
6. Troubleshooting
Table 5 - ADSL Loop Extender Troubleshooting
Problem Description
Possible Reason
Suggested Resolution
Equipment does not work
after connected. Status LED
is OFF.
CO side cable is not connected
properly.
Check CO side cable.
No
connection
Business Card
status LED is
always on.
Cables at DSLAM side or
Modem side are not connected
properly.
Correct the cable
connection.

permission of Widearea.
Line quality is worse between
CO and CPE side.
Change good quality cable.
There is telephone before the
splitter on CPE side.
Discard the telephone before
the splitter on CPE side.
Cables linked ADSL Loop
Extender are not connected
properly.
Correct the cable
connection. 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.
