ResumoAT&T has played a major role in the development of national and international standards for 32-kb/s adaptive differential pulse code modulation (ADPCM). This paper highlights the process leading to the standards on 32-kb/s ADPCM recognized by the American National Standards Institute (ANSI) and the International Telephone and Telegraph Consultative Committee (CCITT). The paper briefly describes the algorithm itself and its performance. It concludes with a discussion of applications of ADPCM and the AT&T products and services that utilize ADPCM.
