What is an ADSL line ?  It’s a digital subscriber line (DSL) which offers data communication technology . This kind of line enables faster data transmission over copper telephone lines than a conventional voice modem can provide. It does this by utilizing frequencies that are not used by a voice actual old fashioned telephone call.  A splitter, or DSL filter, allows a single telephone connection to be used for both ADSL service and voice calls at the same time.

At the telephone exchange the line generally terminates at a digital subscriber line access multiplexer (DSLAM) where another frequency splitter separates the voice band signal for the conventional type of network used for voice.  Data carried by the ADSL are typically routed over Telkom’s data network and eventually reach a conventional Internet Protocol network.

Providers like Telkom usually market ADSL as a service for consumers to provide  internet . ADSL is in many places the most common type offered to home users.
