Title (EN) SUBSCRIBER LINE INTERFACE CIRCUITRY WITH INTEGRATED SERIAL INTERFACES
(FR) ÉLÉMENTS DE CIRCUIT D'INTERFACE DE LIGNE D'ABONNÉ AVEC INTERFACES SÉRIE INTÉGRÉES
Abstract:
(EN) Methods and apparatus for communicating PCM and SDI data on a common interface are described. Various embodiments of the common interface include two (580, 582, 1180, 1182) to three (880, 882) signal lines. The signal lines are unidirectional or bi-directional. A clock signal may be provided by dedicated signal line or recovered from frames carried by the signal lines. One embodiment includes a first device (522) coupled (710) to a second device (510) with a bi directional data line (574) and a clock line (572). Frames of data are serially communicated (720) between the first and second devices on the data line. Each frame is synchronized with a clock signal carried by the clock line. Each frame (602) has a portion allocated to data communicated from the first device to the second device and another portion allocated to data communicated from the second device to the first device.
(FR) L'invention porte sur des procédés et un appareil pour communiquer des données PCM et SDI sur une interface commune. Divers modes de réalisation de l'interface commune comprennent deux (580, 582, 1180, 1182) à trois (880, 882) lignes de signal. Les lignes de signal sont unidirectionnelles ou bidirectionnelles. Un signal d'horloge peut être fourni par une ligne de signal spécialisée ou récupéré à partir de trames transportées par les lignes de signal. Un mode de réalisation comprend un premier dispositif (522) couplé (710) à un second dispositif (510) avec une ligne de données bidirectionnelle (574) et une ligne d'horloge (572). Des trames de données sont communiquées en série (720) entre les premier et second dispositifs sur la ligne de données. Chaque trame est synchronisée avec un signal d'horloge transporté par la ligne d'horloge. Chaque trame (602) a une partie allouée à des données communiquées du premier dispositif au second dispositif et une autre partie allouée à des données communiquées du second dispositif au premier dispositif.
