TIA TIA-1042-A PDF

This document details definitions, methods of measurement, and minimum electro acoustic performance characteristics for Code Division Multiple Access (CDMA) mobile stations. These standards are intended to ensure a level of electro-acoustic performance approaching that defined by the ITU-T for PSTN circuits. These electro-acoustic requirements are applicable to all Speech Service Options supported by the mobile station. These requirements are applicable to mobile station handsets that send and receive sound propagating exclusively through air. Requirements for handsets that send or receive sound by other means (e.g. tissue conduction or bone conduction), loudspeaker, headset, and hands-free configurations are not addressed in the current document and are for further study. Test methods are recommended in this document; however, methods other than those recommended may suffice for the same purpose. The electro-acoustic requirements in this document are not applicable to SO77 operation.
