Default RFI from Switched power supply

Thanks guys!

I'm going to play with some filters and beads. See if that works
first. I agree that it actually is Verizon's problem (and I will
inform them when I can't get it resolved.) but I want to see if I can
avoid the headace of trying to explain them the issue. $5 worth of
filter/beads might not be so badly spend if it works. Oh by the way...
found out that the powersupply is 48V! (my bad!)

Well, it won't work from a 12V battery then... g

The only 48V supplies that I am used to are ones that take up, a whole
wall in a communications vault...not quite the same!


Wow.. I have FIOS here in Texas and I don't have excessive noise from
it. 48 Volts? That seems strange because it has only a 12V battery
for backup power.

Are we sure that the problem is not the network wires or something
else?

I guess, I'm asking how did we determine that the power supply was the
problem? (Aside from the fact that this is normally the problem..)

Call Verizon and complain to get the problem fixed! The noise also may be
interfering with other people (for example, short-wave radio listeners) who,
because they don't have technical knowledge like you, wouldn't have a clue
what's causing all the noise.
