adsl filter with L.E.D indicator

[rnbguy]

Hi All,

I have a question, I am trying to build an adsl filter or passive device, which contains an L.E.D indicator if ADSL frequencies are detected on the line.

The device does not need to handshake or anything, just detect dsl frequencies (not just voltages)?

Am i asking for something from the future or is this possible given what we have today?

Yes, you need to detect high frequencies.

do you want the DSL to work with this connected? (I ask because if you don't then loading down the phone line is less of an issue)

Thanks for the reply, okay so I would like to either have the dsl stil work on the line while the led indicates status or alternativly if the dsl needs to go down its only when user presses a 'test' button to initiate test. ,
