It normally takes only a few minutes to install ADSL in a home or business.  A technician normally visits the premises to ensure that the telephone line is able to carry a strong, clear signal. 

The ADSL technician will then connect the phone line to an ADSL modem and the modem to the computer.  If multiple client computers are to share an ADSL Internet connection, a router is installed between the ADSL modem and the computers. 

ADSL broadband modems can either be purchased or rented.  Many ADSL providers include the cost of the modem in their monthly service charge.
