Abstract :
The CCITT expert group on speech quality, formed in part to derive methodologies for evaluating new speech technologies, is emphasizing the assessment of digital circuit multiplication and packetized voice systems. Study group XII was requested to assess the performance of digital circuit multiplication equipment (DCME). The authors discuss DCME terminology, applications, testing alternatives, and issues that need to be addressed
