Prior to the wires-only installation method a BT engineer had to visit your home to add a splitter to your BT master socket. The splitter separates the frequencies used for the ADSL and the phone.
Wires-only is a self-install method and became available in 2002. A wires-only installation means an engineer is not required to visit you to install the ADSL service. This is because you install simple micro-filters – which work in the same way as the BT installed splitter socket - to your phone sockets.
You can still decide on which type of installation you would like, however the engineer method is far more expensive.
