The purposes of monitoring are to determine which of the many possible such circuits carrying this traffic are being used for digital voice and to obtain irrefutable evidence of such use. The state-of-the-art of voice digitizing and data encryption technology is reviewed with the conclusion that it is quite feasible to use such an interconnection for the purposes of digital voice communication"--Abstract. |
