Abstract
Un dispositivo de conmutación de tiempo digital que incluye al menos un par de registros de conversión similares, respectivamente de entrada y salida,,teniendo cada uno una capacidad de n/2 bits, dispuestos en una configuración paralelo pero cambiando en direcciones puestas, elementos de transferencia para transferir selectivamente los contenidos de las células del registro de conversión de entrada 1, 2, 3 ....(n/2 - 1),.n/2, a la n/2, (n/2 1),...3, 2, 1 del registro de salida, respectivamente, bajo el control de elementos de control; comprendiendo dichos elementos de control una memoria de circulación, circulando en sincronismo con el registro de entrada,. en dónde se almacena la información referente al tiempo de transferencia requerido de cada una de dichas puertas de transferencia, una fuente de identificaciones de puertas de transferencia y elementos para-producir una señal de control para cada puerta de transferencia cuando existe coincidencia del tiempo de transferencia para esta puerta con la identidad de la puerta.
