Isolation Test

First remove ALL devices that are connected to the telephone line used by your ADSL modem. The reason this is asked, is to try and eliminate any hardware issues at this stage at your premises that may be interfering with your ADSL line sync/speed You should do this systematically using the following check list:

1.Power off your ADSL modem and unplug all cables.

2.Unplug all telephone handsets and cordless phones, remembering the extension in the garage, bedroom etc.

3.Unplug all fax machines

4.Remove all ADSL filters

5.Remove all telephone double adapters/splitters

6.Remove all telephone extension cables

7.Unplug Foxtel/Austar Digital TV connection to the phone line

8.Unplug any building alarm. If unable to unplug the telephone line from the alarm, then power off the alarm unit.

When you are certain that all devices that use the telephone line at your premises have been unplugged, proceed to the next step.

Plug your 'line' cable (RJ11) into the back of your modem, and then plug the 'line' cable (RJ11) directly into your telephone socket.

Plug your ADSL modem's power supply into a power outlet, but do not turn the power on yet.

Do not have anything else plugged into any other phone outlet in your premises at all.

This means to physically unplug any other device currently plugged into any telephone socket on the same number as your ADSL service.

This also includes digital foxtel, back to base alarm systems and facsimile machines.

Do not use any phone double adaptors of phone extension leads at all.

Using a short telephone cable, less than 2 meters long, plug into Telephone or Line port of the ADSL modem and then directly into the first telephone point in the premises. Check that the telephone cable is firmly plugged in and not damaged.

DO NOT place an ADSL filter between the modem and the telephone point on the wall.

Plug your Ethernet (RJ45) cabling into the back on the modem, and then into the back of your computer.

Turn the power to your modem on, from the power outlet.

Turn your modem ON.

Identify the light on the modem that tells you when your modem is connected to the ADSL service. Sometimes this is called LINK, LNK, SYNC or WAN, depending on the modem type. In most cases the light will be steady and not flashing when it is connected

If the light is not flashing at this point there is a physical link to the exchange.

Plug in each of the devices you unplugged in the first step, ensuring that you have correctly installed an ADSL filter on the telephone line between the device and the telephone wall socket.

Check the light on the ADSL modem that indicates you have a connection after you plug in each device. If the light starts flashing after you plug in a device this indicates the device or filter is faulty. Check that the filter is correctly installed (please see the Hardware Installation Guide to confirm). Replace with another filter.

Repeat this procedure for all telephones, faxes, digital TV, building alarms, remembering to install the filter and check the ADSL modem after adding each device.

Repeat the procedure for all telephone double adapters/splitters and telephone extension cables installed, checking the ADSL modem after each installation.
