Title (EN) VOICE/DATA ACCESS CONCENTRATTION FOR NODE IN AN EXPANDABLE TELECOMMUNICATIONS SYSTEM
(FR) CONCENTRATEUR D'ACCES PAROLE/DONNEES POUR UN NOEUD DANS UN SYSTEME DE TELECOMMUNICATION EVOLUTIF
Abstract: front page image
(EN)Apparatus operable as a standalone, open programmable switch, a node, an expandable telecommunications system, or a gateway includes a voice/data access concentrator (VDAC) card for providing voice over IP (Internet protocol) capability. The VDAC card includes an array of digital signal processors (DSPs) which may be programmed to perform desired protocol conversions between circuit-based protocols, such as T1, E1 or J1, and packet-based protocols, such as IP. The apparatus is scalable and may readily incorporate other cards which provide both subscriber supplementary services and network signalling as required to meet the needs of a paticular application.
(FR)L'invention concerne un appareil se comportant comme un commutateur programmable ouvert autonome, un noeud, un système de télécommunication évolutif ou une passerelle comprenant une carte de concentrateur d'accès de parole/données (VDAC) permettant la transmission vocale via le protocole Internet (IP). La carte VDAC comprend un réseau de processeurs de signaux numériques (PSN) susceptibles d'être programmés pour effectuer des conversions de protocole souhaitées entre les protocoles utilisant un circuit, notamment T1, E1 ou J1 et les protocoles utilisant des paquets, notamment IP. L'appareil à géométrie variable peut intégrer d'autres cartes fournissant des services supplémentaires aux abonnés ainsi qu'une signalisation réseau afin de s'adapter aux besoins d'une application particulière.
