ADSL user guide

Asymmetric digital subscriber line (ADSL) is an ‘always on’ high speed internet service. It’s delivered via the copper pair telephone line, which also carries voice traffic.

ADSL availability factors

  1. You need a continuous telephone line all the way back to your local exchange

  2. The line mustn’t have any network conditioning devices or attachments

  3. The local exchange must be ADSL enabled

ADSL equipment and installation


Here’s what you need:

  1. a standard telephone line

  2. an ADSL modem router connected to your ISP

  3. installation software for the modem router

  4. a telephone cable (also known as RJ-11 cable)

  5. an in-line or micro filter for each installed telephony device (up to 3 devices) to avoid interference between your ADSL and fixed line telephone connection, or

  6. a central filter (master splitter) if you have more than three telephony devices installed. If you need a central filter it may need to be installed by a registered cabler.

If a registered cabler isn’t needed, you may be able to install the devices yourself. Otherwise your internet service provider may be able to arrange installation for you.
