DSL
Stands for Digital Subscriber Line and is basically implemented as aDSL, meaning the download speed is faster than the upload speed. This type of internet connection connects via your telephone line, allowing you to use both your phone and internet at the same time using a DSL filter.
You’ll need an aDSL / aDSL2 modem router that plugs into your phone line. These are usually supplied by your ISP, so check with them before buying.
