No, we are not converting the digital info to analog.  We are taking digital
info, encapsulating it in ip, then sending that over an analog carrier.  The
data is not converted to analog.

Take a towel, put it in a watertight tube, and deliver it over seas by
submarine, and then remove it from the tube on the other side.  The info is
only carried by the analog, not converted to it in the sense of the analog is
used as nothing but a transport agent.
