Abstract
UN SISTEMA PARA SUPERVISAR UNA RED EN LA CUAL UNA ESTACION (1) CONECTADA A LA RED INCLUYE UN TRANSMISOR (2) Y UN RECEPTOR (3). EL TRANSMISOR (2) EMITE DE SALIDA UNA SEÑAL MODULADA CON TRAFICO SALIENTE SOBRE LA RED Y EL RECEPTOR (3) RECIBE UNA SEÑAL DE LA RED MODULADA CON TRAFICO ENTRANTE. LA ESTACION (1) INCLUYE UN CIRCUITO (7) DE SUPERVISION. EL CIRCUITO (7) DE SUPERVISION INTRODUCE UN RETARDO VARIABLE EN UNA SEÑAL DEL TRANSMISOR (2) Y COMBINA LA SEÑAL RETARDADA CON LA SEÑAL RECIBIDA DE MODO QUE PRODUCE UNA SALIDA DEPENDIENTE DE LA CORRELACION DE LA SEÑAL DEL TRANSMISOR (2) Y LA SEÑAL RECIBIDA EN EL RETARDO DADO. EN UN EJEMPLO PREFERIDO, LA RED ES UNA RED OPTICA Y EL RETARDO SE INTRODUCE POR UNA LINEA DE RETARDO PROGRAMABLE.
