A method and apparatus in an optical network unit for identifying signals for a set of communication devices in a signal stream having signals for a number of different sets of communication devices. Each optical network unit ONU (335) includes a common control unit CCU (350) which uses a content addressable memory CAM for identifying sets of signals that need to be extracted from the signal stream and transmitted to a first set (392, 394, 396, 398) of communication devices; and identifying time periods for inserting sets of signals from a first set of communication devices into a signal stream.

L'invention porte sur une méthode ainsi que sur le dispositif correspondant permettant, dans une unité de réseau optique, d'identifier des signaux relatifs à un ensemble d'unités de communication dans un train de signaux pourvu de signaux relatifs à un certain nombre d'ensembles différents d'unités de communication. Chaque unité de réseau optique (ONU) (335) renferme une unité de commande centralisée (CCU) (350) utilisant une mémoire autoassociative (CAM) pour, d'une part, identifier des jeux de signaux à extraire du train de signaux et à transmettre à un premier ensemble d'unités de communication (392, 394, 396, 398) et, d'autre part, identifier des tranches de temps aux fins de l'introduction de jeux de signaux d'un premier ensemble d'unités de communication dans un train de signaux.
