Abstract
Unidad de señalización para central telefónica, que incluye un órgano de mando, unidad destinada a cambiar informaciones de señalización procedentes de una unión para señales de impulsos codificados, denominada unión MIC, y aunque se presentan en forma de multipletes que son colocados en tramas y que son identificados por un código de emplazamiento para definir su lugar con relación a un multiplote de sincronización y provista de una memoria de recepción para almacenar los multiplotes de señalización procedentes de la unión MIC y para hacerlos disponibles, en hilos de exploración, para el órgano de mando, de una memoria de emisión para almacenar los multiplotes de señalización suministrados por hilos de distribución por el órgano de mando y para permitir su emisión en la unión MIC.
