2. AER800-4PL Box

AER800-4PL Box

The AER800-C1PL modular card system allows for plug and play installation of new subscribers. Wiring terminals on the backplane connect to the existing copper loop plant.

3. AER800-8PL Box

AER800-8PL Box

The backplane of the AER800-PL series enclosures contain wiring terminals for connecting the extender to the existing loop plant. “CO” connects the signal line from the DSLAM to AER800-C1PL; “CPE” connects the line to the customer modem

4. AER800-C1PL Subscriber Card

LED lights indicate power status. Additionally, the AER800-C1PL cards contain DIP switches designed to operate with different CO telephone switches, please follow the following picture:

As you can see, the switches are default setting on “LOW” when ex-work, which requires that the distance L1 from CO to the ADSL loop extender must be longer than 2.8km on 24AWG or longer than 2.3km on 26AWG. At this time, the ADSL loop extender’s working current is 4.2mA.

In case that L1 couldn’t be longer than 2.8km on 24AWG or couldn’t longer than 2.3km on 26AWG, you can set the switched to “HIGH”. At this time, the ADSL loop extender’s working current is 6.2mA, and two things are needed to be noted:

1. L1 must be longer than 2.4km on 24AWG or longer than 2.0km on 26AWG;

2. The threshold of telephone switch is higher than 6.2mA.

Installation

Installation Procedure

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.

2. ADSL Loop Extender Installation

(1) The AER800-1/4/8PL 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-C1PL card into the AER800-4/8PL 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-C1PL card is operational.

(4) After confirming that all the twist-pair cables are connected correctly, and the AER800-4/8PL is securely installed, the extender will function 10 seconds after power is steadily applied.

Attention:

“A” and “B” represent tip and ring of the twisted-pair. No polarity.

Troubleshooting

Troubleshooting

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 Sync.	AER800-C1PL 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.
		ADSL 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.
There is noise on the user’s telephone line.		CO/CPE cable is connected to ground or the wire insulation is faulty.	Check the cables.
There is noise on the user’s telephone line.		Possible electromagnetic interference.	Check to ensure the extender is not located near any high voltage equipment.
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.
		SNR Margin too low.	Increase the SNR margin setting in the DSLAM to 6 or more.
		Bit Error Rate too High.	Increase SNR Margin setting in the DSLAM.
		Data profile is too high for this circuit.	Lower the minimum data rate in the DSLAM.
