Recommendation ITU-T P.1110 describes performance requirements and test methods for wideband hands free communication in motor vehicles. This Recommendation covers: -built-in hands-free systems, -aftermarket hands-free car kits, -corded headsets, and -wireless headsets to be used in motor vehicles for communication. This Recommendation addresses the test of complete systems as well as the subsystems hands-free microphone and the telephone with short-range wireless transmission link used to transmit the speech signals from the hands-free system to the mobile network. For testing purposes, the test set-up and the recommended environmental conditions are described. The methods, the analysis and the performance parameters described in this Recommendation are based on test signals and test procedures, as defined in Recommendations ITU T P.501, ITU T P.502, ITU T P.340, and ITU T P.380.
