      OK, sounds familiar;unreasonable but reasonable for politics...there
      was a crash program in the 1970's to get thousands of domestic PSN
      circuits rerouted onto satellite just to fill it up for regulatory
      reasons; then later they were rerouted back on L & radio...btw some
      of these circuits were split,transmit & rec, between the bird &
      terrestial,creating tricky echo cancelling schemes.
