ITU-T G.9711 (2021) Amd. 1 (04/2022)

La Recommandation UIT-T G.9711 spécifie une technologie d'accès large bande de plusieurs gigabits basée sur l'infrastructure existante des paires de fils et des câbles coaxiaux qui ont été déployées au départ pour le service téléphonique ordinaire ou les services de télévision. Les équipements mettant en œuvre cette Recommandation peuvent être déployés depuis les points de distribution des réseaux à fibres optiques (fibre jusqu'au point de distribution, FTTdp) situés tout près des locaux de l'abonné, ou à l'intérieur des bâtiments, y compris les unités d'habitation multiples (MDU) et les infrastructures commerciales (fibre jusqu'au bâtiment, FTTB). Cette Recommandation permet une transmission asymétrique ou symétrique à un débit de données net cumulé pouvant aller jusqu'à 8 Gbit/s sur les fils métalliques en utilisant jusqu'à 424 MHz de spectre et fournit les fonctionnalités nécessaires pour supprimer la télédiaphonie (FEXT) et la paradiaphonie (NEXT) entre plusieurs paires de fils.
L'Amendement 1 (2022) a pour objet de spécifier ou de corriger:
– poursuite du paramètre de redistribution de bande passante dynamique (DBR-PT) et redistribution de bande passante dynamique (DBR) bidirectionnelle pour faciliter l'accélération de la DBR;
– diagnostics et contrôle de l'assignation dynamique de créneaux temporels (DTA);
– objets de densité spectrale de puissance en aval communs à toutes les liaisons du groupe P2MP;
– demande de configuration de trame en amont; et
– prise en charge de la fonctionnalité DTFO en mode d'accès AMRT/AMRF P2MP.
Les modifications qui concernent des éléments corrigés sont indiquées par les marques de révision suivantes.
Les modifications qui concernent de nouveaux éléments sont indiquées par les marques de révision suivantes.
NOTE – Certaines modifications concernant de nouveaux éléments mettent à jour les modifications correspondantes concernant les éléments corrigés.
