1.General Description
In order to supply much higher bandwidth to users, telecom operators have already
upgraded the ADSL2 + network to VDSL2 network step by step. But the VDSL2
bit-rate decreased rapidly with the increase of distance.
The VDSL2 loop extender is installed on the loop between the VDSL2 DSLAM and
the user’s modem, amplifying VDSL2 signal, extending the coverage of VDSL2
effective bandwidth, improving the downstream bit-rate and bring more stable and
reliable VDSL2 broadband service to those longer users.
Feature:
➢Fully compatible with ITU-T G.993.2, G994.1
➢Fully compatible with all the VDSL2 equipments which comply with these above
standards
➢Fully compatible with VDSL2 band profile：8a，12a，17a,30a；PSD mask：EU32，
EU64
➢At 2.0 Km ~ 2.7 Km (24AWG) distance range, downstream bit-rate has
increased significantly with the highest increase of 60%
➢Powered by PBX, no remote power supply required
➢POTS is unavailable
➢IP66 Rated enclosures
➢High grade protection from lightening.
➢Low power consumption and more environmentally friendly
➢Easy to install, deploy, and maintain. no switch to config
➢This solution is a cost-effective, quick-to-market solution

The backplane of the AER800-xPVLseries enclosures contain wiring terminals for
connecting the extender to the existing loop plant. “CO” connects the line from the
DSLAM to AER800-C1PVL, “CPE” connects the line to the customer modem.
5. Installation Procedure
5.1 Unpack
When unpacking the equipment, be sure to check the contents of the packaging for
completeness against your purchase order. Notify your supplier immediately if any items
are missing.
Note: Please save packing material. All equipment returned must be packed in

the original packing material.
Be sure to inspect the equipment for shipping damage, including bent or loose
hardware, and broken connectors. If the equipment appears to have been damaged in
transit, please contact your supplier.
5.2 Line Power ADSL Loop Extender Installation
(1) The AER800-1/4/8PVL Box can be installed in a junction cabinet, pedestal, or pole
mounted via the supplied mounting brackets. Once mounted, ground the unit via the
supplied grounding screw on the bottom outside of the box.
Attention: Copper-core wire with no less than 2.5mm2(13 AWG) diameter 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. Grounding reliability is the best way to protect the unit against lightning
damage.
(2) Insert the AER800-C1PVL card into the AER800-4/8PVL box.
(3) Connect the line from the DSLAM to the “CO” terminal, and connect the line linked
to the customer’s modem to the “CPE” terminal. Once the “CO” pair is connected, the
power LED will come on to indicated the AER800-C1PVL card is operational.
(4) After confirming that all the twist-pair cables are connected correctly, and the
AER800-4/8PVL is securely installed, the extender will work 10 seconds after power is
steadily applied.
Attention:
“A” and “B” represent tip and ring of the twisted-pair. No polarity.

6. Troubleshooting
Checks at the Central Office
➢check that there are no leakage currents on the line (measured at the CO). With no
extender on the line, current should be essentially zero. With a line powered loop
extender, you will read about 15mA .
➢check the VDSL2 DSLAM configur, is band profile 8a,12a,17a or 30a, is PSD mask
EU32, EU64
Checks at the Pedestal
➢The minimum distance (on 24AWG) from the Central Office for extender installation
is 3Kft for line power extender.
➢Is the LED on the extender on?
➢Is the extender grounded? Bonded? The ground, cable sheath, and extender should all
be bonded together at the extender and as frequently as possible elsewhere. Lack of
bonding will allow significant interference from AC power, AM radio, electric fences
and similar problems. Lack of bonding will also make you a prime target for
lightning and other surges. If you can’t bond, don’t ground the extender. If you
can’t ground, you have to take steps to isolate the enclosure from ground too.
Grounding & Bonding together is preferred.
➢Does the loop distance match the installation condition? . If not, re-check distances,
connections and eliminate loads.
➢Does modem sync at the pedestal without the extender connected? The sync rate at this
location is the maximum the extender can deliver down range. If you can't get sync,
the extender will not work at this location.
Checks at the Customer Premise
➢Customer premise should be at least 3Kft (on 24AWG) from the extender for optimal
performance. It will work at shorter distances with sub-optimal performance.
➢Does the modem run without errors?

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
Sync.
AER800-C1PVL
status LED is on.
Cables at DSLAM or
Modem side are
connected on wrong
side.
Correct the cable connection.
Line quality issues.
Diagnose cable for proper
Ohms/Attenuation values.
There is a telephone
before the splitter on
CPE side.
Discard the telephone before the
splitter on CPE side.
VDSL2 loop extender is
not connected properly.
Correct the cable connection, or
check whether the distance between
the DSLAM, extender, and Modem
is within recommended values.
L1 or L2 is too short.
Check that loop extender placement
meets engineering requirements.
SNR Margin is too high.
Reduce SNR Margin setting on the
DSLAM until a connection is made.
We suggest using SNR Margin <
10. Testing with SNR margin = 1
can provide useful hints during
troubleshooting.
Internet is slow, frequent
disconnects.
Possible PC issues,
virus, hardware
malfunction, etc.
Verify issue with test set or a
known good piece of hardware.
Check statistics on modem and
DSLAM.
Parallel open wire at
CPE is too long or the
connector is rusted.
Change the parallel cable to copper
twisted-pair.
The CPE side cable has
too many connectors.
Avoid exposed connectors, use
good quality cable.
