That is correct. The US does not, to my knowledge, have conducted emission
tests for communication lines which is what I believe John is talking
about. The FCC does accept data taken from CISPR 22 testing but only for AC
line conducted tests and radiated emissions.

It may be correct for FCC: the requirements in Europe are rather
different, and too complicated to explain here. See clause 9 of ***the
latest edition of*** EN 55022.
