36 CFR Part 1194 - Proposed Information and Communication Technology (ICT) Standards and Guidelines NPRM - Preamble

410.5 Digital Encoding of Speech (Section-by-Section Analysis)

This section proposes to require ICT with two-way voice communication to transmit and receive digitally encoded speech in the manner specified by ITU-T Recommendation G.722, a consensus standard for encoding and storing digital audio information that is incorporated by reference in 508 Chapter 1 and 255 Chapter 1. An exception for closed systems would exempt such systems from conformance to ITU-T Recommendation G.722 provided that they conform to another standard that ensures equivalent or better acoustic performance and support conversion to ITU-T Recommendation G.722 at their borders. This provision was recommended by the Advisory Committee to help improve auditory clarity for persons with hearing impairments. It is new to both the 508 Standards and 255 Guidelines.
