If you subscribe to DSL internet service using your telephone line, DSL filters must be plugged into EVERY phone jack that has a phone connected to it. The DSL signal can cause static, noise, squealing (similar to fax tones), caller ID disruption and other issues on yourline.

Is DSL line the same as phone line? DSL is a very high-speed connection that uses the same wires as a regular telephone line. You can leave your Internet connection open and still use the phone line for voice calls. DSL doesn't necessarily require new wiring; it can use the phone line you alreadyhave.

Do I need a DSL splitter? An ADSL Splitter is usually needed only if the same line (twisted pair, usually) carries both the DSL signal and the normal phone line asit filters off the high frequencies of the modem from the phone line.
