General Description
ADSL technology has great advantages in terms of bandwidth and performance;
however, long loops can create difficulties providing consistent broadband
services.
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.
AEC-B4P-D48 is one type of the Power Supply. It can convert DC48V to 4х
DC116V. It can support one AER800-8P-O, or 4 AER800-1Ps, or 4
AER800-2Ps.

Installation Environment
Before installation, the DC 48V power supply and reliable ground connection
should be assured. The customer should order the corresponding type of power
supply according to the available power source.
If any difficulties are encountered during the installation process, contact
supplier.
Installation Procedure
UNPACK
Unpack equipment carefully; check for completeness against the purchase order.
Notify supplier if items are missing.
Note: Save packing material. All equipment returned must be packed in the
original packing material.
Inspect equipment for shipping damage, including bent or loose hardware, and
broken connectors.
If equipment was damaged in transit, contact supplier.
BEFORE INSTALLINGTHE 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 DC 116V. Do not touch wire A and wire B simultaneously, or
allow wires to contact anything!

In figure 2, the indicators PWR11~PWR22 indicates the status of the equipment.
After power supply is connected, press the button K11~K22, and the
corresponding PWR indicator should be solid on. Flashing indicator indicates
short circuits or over-current alarm condition.

In figure 3, the outlet J1 and J2 are the 116V output terminal. You can get 2х
116V(no polarized) from each outlet. You can connect DC48V through the 2×
3-core power cord.

If the ADSL Loop Extender is installed in a remote location without local power
available, an additional copper pair(L3 as shown in Fig. 1) is required for power.
The supply voltage will pass through power converter and feed to this additional
pair.
②Ground
Connect the power supply ground.
③Connect power cord(do not apply power yet)
The supplied accessories include power cord for DC 48V. Connect it to the DC
48V power source with good connection.
Attention: ADSL Loop Extender’s power supply should NOT be turned on
until the Loop Extender installation is finished.
Troubleshooting
Table 3 AEC-B4P-D48 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.
