ITU-T P.381 (03/2017)

Requisitos técnicos y métodos de prueba aplicables a la interfaz universal de auriculares con cable de terminales digitales móviles

La Recomendación UIT-T P.381 especifica las características físicas y electroacústicas esenciales de la interfaz universal de auriculares y describe los métodos de prueba correspondientes. En los últimos años, se ha observado una gran utilización de interfaces de auriculares de 3,5 y 2,5 mm de diámetro en terminales móviles digitales. El consumidor tiene ahora la posibilidad de elegir libremente los auriculares facilitados originalmente por el fabricante del terminal u otros ofrecidos por separado. Sin embargo, la calidad de servicio (QoS) y la calidad percibida (QoE) que experimentan los usuarios dependen a la vez del funcionamiento eléctrico de la interfaz y de la compatibilidad entre el terminal y los auriculares.
