Overview

ADSL technology has great advantages in terms of band-width 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.
AER800-4/8P can extend the coverage of 4/8 lines of ADSL 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 extender 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 

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 repeat-er 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 cover 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.

Installation Environment  

Before installation, the DC 48V or AC 110-240V power supply and reliable ground connection should be assured. The cus-tomer 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.

• Unpack the package.

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

• Install the ADSL repeater

Secure the enclosure

(1)Install the repeater

Attention: 

Copper-core wire with no less than 1.5mm2 section area is re-quired 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 grounding point.

(2)Install the repeater in cabinet box

Remove the mounting brackets from repeater's enclo-sure and secure the repeater in the available room of cabinet box.

Attention:

Copper-core wire with no less than 1.5mm2 section area is re-quired 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 grounding point.

Connecting the cable for AER800-4/8P

As illustrated in Fig. 3 below, the equipment is com-posed by 2 parts. Each part can support ADSL signal extension for two channels.

Fig. 3 - AER800-4/8P Connection Terminals Diagram

Step by step cable connection procedure is shown as follow.

•  Remove about 10mm insulation coat of the twist-pair for CPE side. Press the orange part of the wiring termi-nals marked as "CPE31", insert the wire end and secure it. Do this for terminal A and B separately.
• Remove about 10mm insulation coat of the twist-pair for CO side. Press the orange part of the wiring termi-nals marked as "CO31", insert the wire end and secure it. Do this for terminal A and B separately.
• Connect the power supply cable

The power supply cable here is the normal twist-pair phone line. One pair power supply cable can support 2 channels, PWR3 support 31/32 these 2 channels, and PWR4 support 41/42 these 2 channels.

The power supply cable here is the normal twist-pair phone line. One pair power supply cable can support 2 channels, PWR3 support 31/32 these 2 channels, and PWR4 support 41/42 these 2 channels.
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 ca-ble, finally goes into PWR3/PWR4 of ADSL repeater. When local power supply is desired, the supply voltage from wiring box will go through twist-pair and into the ADSL repeater di-rectly.

Attention: 

a) "A" and "B" represent A and B wire of the twist-pair. No polar-ity.

b) Before power up the system, please make sure all the con-nections are correct.
