Terminal Equipment (TE) - Telephony for hearing impaired people - Characteristics of telephone sets that provide additional receiving amplification for the benefit of the hearing impaired

Le présent document spécifie les caractéristiques de performance électro-acoustiques des terminaux téléphoniques conçus pour une application directe à l'oreille (comme les combinés traditionnels, les casques d'opérateurs) et fournissant, à l'écouteur, une amplification supplémentaire comparée à l'équivalent pour la sonie à la réception spécifié dans la norme pertinente sur les terminaux. Ce document s'applique aux postes téléphoniques pouvant être reliés au réseau téléphonique public commuté (RTPC), ou au point de référence S et T coïncidents de l'accès de base du réseau numérique à intégration de services (RNIS). Elle ne traite pas des dispositifs mains libres et à haut parleur, ni de l'amplification supplémentaire à l'émission destinée aux personnes ayant des difficultés d'élocution.
