Overview

ADSL technology has great advantages in terms of bandwidth and performance and is the major broadband access technology. However, the longer the distance between CO and CPE, the lower the speed ADSL can achieve.
AER800-1P can extend the coverage of single ADSL line and resolve the above issue very well. It will provide systems with higher performance-to-cost ratio for telecom operators, improve the equipment utilization rate, optimize the network and boost the ability to compete. Along with protection of current investment, this ADSL repeater can have more broadband access subscribers and value-added services accommodated by extending coverage of existing ADSL network. As the result, it will bring back huge return.

Function and Features

ADSL Repeater

• Extend the transmission distance between CO DSLAM and CPE Modem. Ensure the upstream/downstream rate is no less than 128kbps/512kbps.
• Deploying with traditional ADSL system: the repeater can extend the range between DSLAM and Modem from 3.5KM to 5.5KM~6KM without affecting existing POTS service;
• Deploying with ADSL2+ system: the repeater can extend the coverage range of DSLAM from 5.5KM to 6KM~7.5KM without affecting existing POTS service.
• Avoid customer loss due to broadband service unavailability caused by extra long distance.
• Improve network bandwidth and service quality.
• Comprehensive thunder lightening, over-current and over-voltage protection.
• Easy to install, deploy and maintain.
• Fully compatible with all ADSL/ADSL2+ system.

ADSL Repeater Power Supply 

• The power source includes remote supply and local supply. For the ADSL/POTS coexisting line user, extra wire pair is needed to power the ADSL repeater if remote supply is required.
• Single channel output power is less than 10W.
• Easy to install and deploy.
• User optional AC110-240V or DC48V supply voltage. No polarity for DC input to easy the installation.

Physical Structure 

AER800-1P

• Metal enclosure
• Wiring sockets on front panel for CO and CPE side signal wiring and power supply wiring
• Metal mast on front panel for ground connection
• One switches on front panel for controlling the working status of line 1 or line 2.

AEC-B1P

(If AER800-1P is deployed with AEC-B4P, please refer to user manual of AEC-B4P.)

• After power supply is connected, the power indicator should be solid on. Flashing indicator indicates short-circuits or over-current alarm condition.
• Three-core power cord with plug: used for AC110-240V power input.
• Power output: 116V power output cable which is already connected to the terminal in wiring box by factory.

Installation Environment

Before installation, the DC 48V or AC110-240V 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.

Installation Procedures

The recommended installation conditions are as follows. Total line loop resistance is about 800ohm to 1600ohm; loop resistance between repeater and CO is about 450ohm to 1260ohm; loop resistance between repeater and CPE is about 200ohm to 900ohm.

• Step 1: Open the package

Open the package and take out the equipment, check items according to the package list. Visually inspect it for signs of damage.

• Step 2: Install the power supply for ADSL repeater. (If AER800-1P is deployed with AEC-B4P, please refer to user manual of AEC-B4P)
• Step 3: Connect the power supply cable

The power supply cable here is the normal twist-pair phone line.

The power supply cable here is the normal twist-pair phone line.
When remote supply is desired, pick the twist-pair available for power supply usage first (L3 as shown in Fig. 2). The supply voltage from wiring box will pass through wiring rack and cable, finally goes into ADSL repeater. When local power supply is desired, the supply voltage from wiring box will go through twist-pair and into the ADSL repeater directly.

• Step 4: Ground

Connect the equipment's ground to CO's grounding terminal directly.

• Step 5: Connect Power Cord

The supplied accessories include power cord for AC 110-240V or DC 48V. Connect it to the AC110-240V or DC 48V power source with good connection. To easy the installation, DC power source connection is not polarized.

Attention: ADSL repeater's power supply should NOT be turned on until the repeater installation is finished.

• Step 6: Install the ADSL repeater
• Step 7: Install the securing box

Equipment is installed in the cabinet box. ADSL repeater can be placed in the box if there is inner room available. Or the repeater can be mounted in the box through supplied mount-ing brackets.

Attention: Copper-core wire with no less than 1.5mm2 section area is required as ground wire. One end of the wire should connect to repeater's ground terminal. The other end of the wire should connect to a good ground-ing point.

• Step 8: Connect the cable

I. Identify and separate the signal twist-pair and power sup-ply twist-pair.

II. Remove about 10mm insulation coat of the twist-pair for first channel CPE side, connect to the "white/green" pair of the ADSL .

III. Remove about 10mm insulation coat of the twist-pair for first channel CO side, connect to the "white/orange" pair of the repeater.

IV. Remove about 10mm insulation coat of the twist-pair for power supply from CO, connect to the "white/blue" pair of the ADSL repeater.

Attention:

a) "A" and "B" represent A and B wire of the twist-pair. No polarity, pls do all the above for wire A and wire B sepa-rately .
b) Before power up the system, please make sure all the con-nections are correct.
c) When the power supply wire is active, do NOT operate the A and B wire of the supply pair simultaneously. The A wire and B wire should be isolated.

• Step 9: Power up 

After confirming that all the twist-pair cables are connected correctly and enclosure is securely installed, power up the system. The ADSL repeater will work in 20 seconds after power is supplied steadily.
