1. General Description
ADSL Loop Extender can extend the coverage of ADSL lines. It will provide
systems with higher performance-to-cost ratio, improve the equipment utilization
rate, optimize the network. This product will allow you to double the number of
subscribers that you can reach while offering more consistent high bandwidth
services to your existing customers.
ADSL Loop Extender is an active element installed in the outside loop plant. It
operates as an amplifier and equalizes the signal. Generally, it is span-powered.
You can use the ADSL Loop Extender Power Supply to provide the span-power.
Figure 1 AEC-RACK and the power card
AEC-RACK is a rack for AEC-C2P or AEC-C1PL embedded. One rack

When the card is AEC-C2P, you can get 2хDC122V or 2хDC155V
from each card, supply power for express Extender. The instruction
of the DC122V/DC155V switch of AEC-C2P, please see the
remark below.
when the card is AEC-C1PL, you can get 1х155V and ADSL signal
from “A2,B2”outlet, supply power for the signal line power
Extender.
AEC-C2P

2. Install the power supply
Attention: ADSL Loop Extender’s power supply should NOT be turned on
until the Extender installation is finished. When the power supply wire is
active, wires carry DC122V or DC155V. Do not touch wire A and wire B
simultaneously, or allow wires to contact anything!
⑴Fix the AEC-RACK in the 19’cabinet, ground the RACK through the grounding
screw in the lower right hand corner at the back of the RACK.
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.
⑵Insert Power Supply card AEC-C2P or AEC-C1PL into AEC-RACK.
⑶Connect the power supply cable
Attention: The cable connecting of AEC-C2P and AEC-C1PL is different,
please make sure the type of your card and follow the respective method
below.
AEC-C2P
An additional copper pair(L3 as shown in Fig. 1) is required for one output power.
The supply voltage will pass through power converter and feed to this additional
pair.

AEC-C1PL
No additional copper pair is required for power. Choose the signal line from the
DSLAM/Switch, connect it to the “A1, B1” terminal of AEC-C1PL. Choose the
signal line linked to the Extender, connect it to “A2, B2” terminal of AEC-C1PL.
Attention: Do not connect the cable linked to the Extender to the “A1, B1”
terminal, and do not connect the cable of the DSLAM /Switch to the “A2,
B2” terminal, or else, the equipment would be damaged.
