Frequently asked questions
What is the difference between DSL and fibre?
DSL sends data as electrical signals over existing copper telephone wire, so speed drops sharply the further you are from the exchange. Fibre carries light along glass strands, giving far higher and more consistent speeds, but it requires new cable to be laid.
Is DSL the same as broadband?
DSL is one kind of broadband, not a synonym for it. Cable, fibre, satellite and fixed wireless are all broadband too, and DSL is generally the slowest of them.
Does DSL tie up the phone line?
No. Unlike dial-up, DSL uses frequencies above those used for speech, so you can browse and make calls at once. A small filter on each socket keeps the two apart.
