Title
(EN) SUPPORT OF LIMITED-FUNCTIONALITY DOCSIS FDX IN A NON-"N+0" CONFIGURATION
(FR) PRISE EN CHARGE DE DOCSIS FDX À FONCTIONNALITÉ LIMITÉE DANS UNE CONFIGURATION NON "N+0"
Abstract
(EN)
A full duplex (FDX) trunk amplifier circuit configured to be coupled between a remote PHY (RPHY) circuit and one or more cable modems (CMs) is disclosed. The FDX trunk amplifier circuit comprises a trunk amplifier circuit comprising an amplifier circuit configured to convey a downstream transmission of a downstream data signal associated with the RPHY circuit in a FDX frequency band and an upstream transmission of an upstream data signal associated with the one or more CMs in the FDX frequency band, based on a direct current (DC) control signal. In some embodiments, the amplifier circuit is configured to convey the downstream transmission in the FDX frequency band and the upstream transmission in the FDX frequency band, at different instances, such that the downstream transmission in the FDX frequency band and the upstream transmission in the FDX frequency band do not overlap.

L'invention concerne un circuit amplificateur de ligne de transfert en duplex Intégral (FDX) conçu pour être connecté entre un circuit PHY distant (RPHY) et un ou plusieurs modems câblés (CM). Le circuit amplificateur de ligne de transfert FDX comprend un circuit amplificateur de ligne de transfert comprenant un circuit amplificateur conçu pour acheminer une transmission en aval d'un signal de données aval associé au circuit RPHY dans une bande de fréquences FDX et une transmission en amont d'un signal de données amont associé auxdits CM dans la bande de fréquences FDX, sur la base d'un signal de commande à courant continu (CC). Dans certains modes de réalisation, le circuit amplificateur est conçu pour acheminer la transmission en aval dans la bande de fréquences FDX et la transmission en amont dans la bande de fréquences FDX à des instances différentes, de sorte que la transmission en aval dans la bande de fréquences FDX et la transmission en amont dans la bande de fréquences FDX ne se chevauchent pas.
