Abstract

Mejoras en sistemas de centrales telefónicas automáticas, del tipo gobernado a registrador y en las cuales la clase de servicio de las líneas está designada por un potencial característico aplicado a un conductor de prueba, caracterizado por el hecho de que al conectarse las líneas que llaman y/o las líneas llamada con el registrador, un conmutador del registrador, que tiene una posición para cada clase de servicio, comienza a moverse desde una posición a la siguiente, hasta alcanzar la posición correspondiente a la clase de línea conectada.Improvements in automatic telephone exchange systems, of the type governed by recorder and in which the class of service of the lines is designated by a characteristic potential applied to a test conductor, characterized by the fact that when connecting the lines that call and / or the lines called with the register, a switch of the register, having a position for each class of service, begins to move from one position to the next, until reaching the position corresponding to the class of connected line.
