Abstract
LA MATRIZ COMPRENDE: UNA PLURALIDAD DE CONVERTIDORES DE LONGITUD DE ONDA (183, ...184) SITUADA EN LAS ENTRADAS DE LA MATRIZ PARA ATRIBUIR UNA LONGITUD DE ONDA A CADA CELULA APLICADA EN UNA ENTRADA DE LA MATRIZ; UNA MEMORIA TAMPON OPTICA (181) PARA ALMACENAR CADA CELULA DURANTE UNA DURACION SELECCIONABLE ENTRE O, TC, 2TC, ...K. TC DONDE K ES UN NUMERO ENTERO Y DONDE TC ES LA DURACION DE UNA CELULA; UNA ETAPA DE ORIENTACION ESPACIAL (182) QUE COMPRENDE UN FILTRO (194, .... 195) PARA CADA SALIDA DE LA MATRIZ, PARA NO DEJAR PASAR HACIA UNA SALIDA DADA MAS QUE LAS CELULAS QUE TIENEN UNA LONGITUD DE ONDA DADA; MEDIOS DE CONTROL (52) PARA CONTROLAR LOS CONVERTIDORES (183, ...184) Y LA MEMORIA TAMPON EN FUNCION DE INFORMACION DE EXPEDICION INDICANDO, PARA CADA CELULA, LA SALIDA DE LA MATRIZ A LO QUE ESTA CELULA ESTA DESTINADA; Y PARA SELECCIONAR LA DURACION DE ALMACENAMIENTO DE CADA CELULA EN LA MEMORIA TAMPON (181) DE MANERA A CONSTITUIR UNA FILA DE ESPERA PARA CADA SALIDA, EVITANDO CONFLICTOS ENTRE DOS CELULAS A CONMUTAR HACIA UNA MISMA SALIDA, Y QUE SE PRESENTA A LA VEZ EN LA ENTRADA DE LA MATRIZ DE CONMUTACION. APLICACION EN LAS REDES DE TELECOMUNICACIONES.
