::. Kitz - Improve your adsl connection speed .::
Plug your phone straight into the test socket via the ADSL filter.If it isn't 'crackling' any more then you you probably have a poor connection within the house.Poor connections give rise to 'crackling' on the phone line and poor ADSL performance due to the electrical noise on the line.Don't fiddle with the wiring unless you are licensed to do so.
