The only time I have seen DSL work without a filter is when the modem is connected directly to the incoming port and no analog device can be connected anywhere in the line. That location gets 60meg down and 20meg up. I am also 100รท certain noone can connect an analog phone as there is no plug available. Reason why I said a filter is needed everywhere is because I have seen locations where the ADSL router was behind a filter, but the phone, connected to a different port, was not behind a filter. The occupant of that house were quick to blame the router and ISP, but had difficulty realising the consistency of the connection dropping as soon as someone picked up the phone or the phone starting to ring. -- Joost -- Sent from my Android device with K-9 Mail.
