Do you need 2 phone lines for DSL?

I heard there was some sort of splitter.

Both data and voice travel on the same line, so you only need one. You need a splitter to avoid interferences.

No, unlike the DSL connection shares your existing phone line. You can surf the internet and talk on the phone at the same time. You might be thinking of a splitter which would allow you to plug in both a telephone and the DSL modem to the same jack. Most DSL providers provide these for free.

The splitter is for the tv, phone and internet and is usually at the router. You do not need two phone lines. When the company comes they will hook everything up for you and using the internet wll not interfer with you phone use at all. DSL comes through the phonelines but does not interfer.

No, you only need one line. The internet signal (dsl) and the phone line run on the same line. the splitter you are referring to is a dsl filter so you can't hear the modem sounds while on the phone.

No, you only need one phone line. A splitter is a small part that you can buy at most hardware stores. It looks like a phone jack on one side, and the other side shows two outlets. One for your phone, the other one, for your DSL modem.

DSL stands for digital subscriber line, which is marketing term used for ADSL (Asymmetric Digital Subscriber Line). It works by splitting communication frequencies into 2 bands, which are transmitted on the same physical line. So 2 phone lines are NOT needed for DSL. A splitter is sometimes used for better sound quality and to isolate any disturbances from data transmission.
