Abstract : Present land-line systems, including microwave links, have been examined from the standpoint of the data transmission performance desired. Test results amply show that these systems are effectively ''out'', if not actually out, for times far in excess of the goals set in this program. It would not be practical to pursue these goals as land-lines now perform. Burst noises and particularly drop-outs, i.e., momentary loss of the circuit, are the problems. On any one occurrence these may last from milliseconds to minutes. (Author)
