High-performance in-line DSL filter for phones or telephone equipment sharing a single phone jack. Meets ANSI T1.421 standards for voice quality and data performance with five filters on the line. Isolates DSL and home phoneline networking (HPN) signals from voice signal for peak data performance and voice quality. Effectively filters one or more phone devices (standard or cordless phone, answering machine, dial-up modem, fax machine, etc.). Use one filter at each phone jack in use in the home or office. Easy to install without tools - just plug the filter cord into any standard phone jack, and plug the phone cord into the filter. Provides a filtered jack for any single-line phone device plus a second unfiltered jack for DSL/HPN connection. The short, detachable cord lets user connect the filter to long phone cords in hard-to-reach areas such as behind heavy furniture or desks.

Much needed DSL filter.
My original filter broke on me a long time ago and I was not able to find a replacement at that time. Just recently did I "discover" this needed tool and I was very happy to see it available on Amazon. Ihooked it in place and voila!!!! my problem is fixed. The delivery, as usual, came as promised.

Works Perfectly
This DSL filter/splitter works perfectly and solved my problem with static interference in my phone line. I place it outside my home in the phone box where the AT&T line comes in. From the splitter one line goes directly to my DSL modem and the other one is used for the voice line. No more having cheap DSL filters for every phone line jack in the home.I also saw a data speed increase too. Defintely worth the money.

Perhaps I could have upgraded things but this was an easy fix and worked well
Because I don't anything about computer hook-ups, when my internet wasn't working I decided to replace my non-functioning filter with the exact type I had. Perhaps I could have upgraded things but this was an easy fix and worked well.
