Digital audio - Digital input-output interfacing - Transmission of digital audio over asynchronous transfer mode (ATM) networks (IEC 62365:2009)
IEC 62365:2009(E) specifies a means to carry multiple channels of audio in linear PCM or IEC 60958-4 format over an ATM layer service conforming to ITU-T Recommendation I.150. It includes a means to convey, between parties, information concerning the digital audio signal when setting up audio calls across the ATM network. The main changes with respect to the previous edition (2004) are: - Second, third, and fourth required formats in 4.3 removed; - 4.3 reformatted, eliminating Table 2, and subsequent Tables renumbered.

La CEI 62365:2009 spécifie un moyen de transporter plusieurs canaux audio dans un format MIC ou CEI 60958-4 sur un service de couche ATM conforme à la Recommandation UIT-T I.150. Elle inclut un moyen d'acheminer, entre les participants, des informations concernant le signal audionumérique lors de l'établissement d'appels audio à travers le réseau ATM. La présente version bilingue (2012-08) correspond à la version anglaise monolingue publiée en 2009. Cette seconde édition de la CEI 62365 annule et remplace la première édition parue en 2004. Les principales modifications par rapport à l'édition précédente (2004) sont: la suppression des deuxième, troisième et quatrième formats requis en 4.3. et le reformatage de 4.3, la suppression du Tableau 2 et la renumérotation des tableaux ultérieurs.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendation
