I've seen this same problem as a result of noisy twisted pair connections.
In our particular case we fixed the problem by replacing the RJ-11 and
RJ-45 connectors we were using.  We had been using connectors, meant for
use on stranded wire, on solid wire.  The result was bad connections which
worked but generated a lot of noise.
