Title
(EN) GROOMING DEVICE FOR STREAMLINING TELECOMMUNICATION SIGNALS
(FR) DISPOSITIF DE REORGANISATION SERVANT A REGROUPER DES SIGNAUX DE TELECOMMUNICATIONS
Abstract
(EN)
A grooming device (18) includes an inbound crosspoint switch (30) that combines proprietary STS-1 signals from any of a plurality of optical terminators (16) into a grouped set of output signals for transmission to a broadband matrix subsystem through dedicated matrix interfaces (20). The inbound crosspoint switch (30) includes a crosspoint matrix (72) that receives each of the plurality of input signal lines at each output signal port and selects which input signal line is connected to which output signal port as determined by a microprocessor controller (78). Each output signal port has a register (90) for storing information as to which input signal line is to be connected to that port. A decoder (92) generates a control signal from the information stored in the register (90) to drive a multiplexer (94) for selection of the appropriate input signal line.
(FR)
Dispositif de réorganisation (18) comprenant un commutateur de points de connexion d'arrivée (30) combinant des signaux exclusifs STS-1 provenant de l'une quelconque d'une pluralité de terminaisons optiques (16) en un ensemble groupé de signaux de sortie, afin de les transmettre à un sous-système de matrice à large bande par l'intermédiaire d'interfaces de matrice réservées (20). Le commutateur de points de connexion d'arrivée (30) comprend une matrice de points de connexion (72) qui reçoit chaque ligne de la pluralité de lignes de signaux d'entrée au niveau de chaque sortie de signaux et sélectionne telle ligne de signaux d'entrée devant être reliée à telle sortie de signaux, en fonction de la détermination établie par une unité de contrôle de microprocesseur (78). Chaque sortie de signaux possède un registre (90) servant à mémoriser l'information concernant ladite ligne de signaux d'entrée qui doit être reliée à ladite sortie de signaux. Un décodeur (92) génère un signal de commande à partir de l'information mémorisée dans le registre (90), afin de commander un multiplexeur (94), de manière à sélectionner la ligne de signaux d'entrée adéquate.
