Ralph, I have Earthlink DSL and the filters were used to separate my voice signal from the DSL signal on the same line. According to my PacBell installer: The need for in-line filters is twofold. First, they prevent high frequency (in the DSL frequency range) harmonics and overtones generated by the telephone from interfering with the DSL modem. Secondly, they prevent high frequency (in the DSL frequency range) noise from appearing at the telephone and potentially decreasing voice quality. Unless either a splitter is installed in the Network Interface Device (NID) or the DSL service is offered over an unused second line, in-line filters are required at every telephone on the premises.
