Abstract

Un sistema para controlar el funcionamiento estable de repetidores, que se asignan por un control central a vías de transmisión de dos hilos con pérdidas, a fin de invertir las pérdidas de dichas vías de transmisión, particularmente en sistemas de transmisión telefónica, caracterizado porque a cada repetidor (V1...Vm) está asignado un detector de oscilación (OD11...OD1m) que cuando, se detectan las oscilaciones que tengan un primer nivel mínimo durante un tiempo mínimo, transmite una primera señal de error al control central (ZSt), porque para todos los repetidores y sus detectores de oscilación asociados individualmente existe un probador de rutina central que se conecta él mismo sucesivamente a los terminales (a,b) de los repetidores libres y que comprende elementos para el cambio de impedancia (IS) con un detector de oscilación central (OD2).
