Abstract

Perfeccionamientos en sistemas de conmutación por división de tiempo para datos de múltiples cadencias, caracterizados porque comprenden; un primer dispositivo de almacenamiento, con un primer número de lugares de almacenamiento para almacenar palabras de control; un segundo dispositivo de almacenamiento que comprende un segundo número de lugares de almacenamiento para almacenar palabras de control, siendo el segundo número de lugares de almacenamiento menor que el primer número de lugares de almacenamiento, no siendo el primer número de lugares de almacenamiento un múltiplo entero del segundo número de lugares de almacenamiento; medios de lectura de almacenamiento para tomar lectura de un modo virtualmente simultáneo de las palabras de control de un lugar de almacenamiento de ambos primero y segundo dispositivos de almacenamiento; y medios de selección, que responden a las palabras de control leídas desde el dispositivo de almacenamiento para transmitir al sistema de conmutación de división de tiempo, para su control, una palabra predeterminada de dichas palabras de control leídas desde el primer y segundo dispositivos de almacenamiento.
