I find plenty of circuits on the web to block ADSL on the phone line, but I need the opposite: I am renting an apartment, and I want to allow them to use ADSL but not telephone: in fact the agreement is I pay for internet connection, but not telephone. My phone company does not provide ADSL without phone.
Therefore, I need to install a hidden filter inside the wall so that they cannot use the telephone. Of course I will remove all telephone equipments, but I want a permanent solution.
Of course I need passive filter, I cannot power it inside the wall.
I guess I need series capacitors, but if I close them on a resistor I need a large value, or I will load the line too much.
Thanks
