   If you have many local outlets, each with its own ADSL filter, that mass
of wiring will itself degrade the ADSL. I have a replacement filter front
for the NTE5, so all my internal wiring is hidden as long as the filter is
working, but the inductors could saturate and not work with more than 4 REN
loading. My ADSL modem is close to the NTE5, with ethernet cables linking
on.
