This is extremely abbreviated, but
here's my 2 1/2 cents worth...
EMC or Electro-Magnetic Compatibility has to do with a
device passing limits imposed on Electro-Magnetic events
egressing the device AS WELL AS ingressing. That is to say,
one part of EMC concentrates on what EM event is exiting
the device - emissions such as CISPR-22A, EN-55022A. Another
part concentrates on what EM events enter the device - immunity
such as EN-61000-4-2 ESD, EN-61000-4-5 Surge, ... EMC is
*supposed* to (don't jump on me now) add to the robustness
of your device.
The United States FCC Part 15 Class A is a self-certification
of equipment. The results are not sent off to the FCC
for registration. You declare that Class A equipment meets
the applicable standards with results from a lab accredited
by the FCC. On the other hand, FCC Part 15 Class B results
are filed with the government and it is the government that
gives the final approval.
Telco is only concerned with protecting the telephone line.
Since most if not all the telco links in all the
different countries around the world are controlled in one
way or another by the governments of those countries,
they do not allow self-certification.
