En un sistema de comunicación y señalización por impulsiones en el cual el portador de las transmisión es un tren de impulsiones espaciadas en el tiempo con relación una a otra y desplazadas en el tiempo de acuerdo con la inteligencia que se transmite el método de hacer funcionar un dispositivo controlado por señales sobre dicho portador para indicar que se efectúa una llamada comprendiendo las etapas de hacer influir una señal sobre las impulsiones de tal portador para producir un intervalo de señalización en dicho tren de impulsiones de recibir dicho tren de impulsiones y de hacer funcionar dicho dispositivo controlado por señales en respuesta a dicho intervalo de señalización.In a impulse communication and signaling system in which the transmission carrier is a train of impulses spaced in time relative to each other and shifted in time according to the intelligence being transmitted, the method of operating a device controlled by signals on said carrier to indicate that a call is made, comprising the steps of influencing a signal on the pulses of said carrier to produce a signaling interval in said train of pulses of receiving said train of pulses and of operating said device controlled by signals in response to said signaling interval.
