Can a microfilterless phone disrupt your ADSL signal?
"Unfiltered connected phones can disrupt your ADSL signal and, if you lose your ADSL connection when the phone rings, there's a rogue, microfilterless phone somewhere in the house."
The above claim makes absolutely no sense to me. Firstly, in a typical Australian installation, the ADSL modem's connection to the phone line is unfiltered. Hence the modem is designed to tolerate the 90VAC 20Hz ring signal. Secondly, the ADSL filter is a low pass filter, ie it is designed to pass voice frequencies but not ADSL frequencies. Hence an unfiltered phone presents the same load as a filtered phone to any voice frequency signal, including a ring tone.
Am I missing something, or is the author in error?
