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.
