Abstract

Red de acoplamiento de varias etapas que presenta un agrupamiento de inversión para una central de telecomunicación por modulación de código de impulsos (central de telecomunicación PCM) a fin de transconexionar mediante cuatro hilos conductores de enlaces entre líneas de conexión con etapas de acoplamiento de tiempo y de espacio, estando constituida la primera etapa de acoplamiento a base de grupos de acoplamiento individuales.
