The filter cuts down the spectrum used by the modem, so you _can't_ put it
between the modem and the line. If you have an objectional noise (a 'hiss'
in my case), you can put it between the phones and the line: the band it
rejects isn't used for voice.  Since my modem branches off my telco
service at the central block, it was easy to put the filter between the
branch serving all phones and branch serving the modem. In fact I only
heard noise on one of our three phones, before installing the filter.
