Abstract
(EN)
A network controller (100) comprising a media access control (MAC) layer, a physical (PHY) protocol layer (110), a PCI bus interface (200), and an auxiliary bus interface (180). The PCI and auxiliary bus interfaces are coupled in the network so as to transmit and receive from a network link, binary digital signals via the MAC and PHY layers. The MAC layer is adapted to process and direct at least portions of the digital signals to an auxiliary bus interface.

(FR)
L'invention concerne un contrôleur de réseau (100) comprenant une couche (MAC) de commande d'accès au support physique, une couche (110) physique (PHY) de protocole, une interface PCI (200), et une interface (180) bus auxiliaire. Les interfaces PCI et bus auxiliaire sont couplées dans le réseau de manière à émettre et à recevoir, via les couches MAC et PHY, des signaux numériques binaires provenant d'une liaison réseau. La couche MAC est conçue pour traiter et diriger vers une interface bus auxiliaire certaines parties au moins des signaux numériques.
