Abstract

Un metodo per misurare in condizioni di esercizio parametri operativi di un circuito (2) di interfaccia e di una kinea telefonica (3) d'utente ad esso collegata, tale circuito di interfaccia comprendendo un primo circuito (6) integrato operante in alta tensione con uscite (R, T) collegate alla linea (3) e seconde uscite (IT, IL) sulle quali sono rispettivamente presenti nel normale funzionamento valori di correnti trasversali e longitudinali della linea (3), ed un secondo (7) circuito (7) integrato operante in bassa tensione tra il primo circuito (6) ed una centralina (8) telefonica, prevede le fasi di:- commutare le uscite (R, T) sui capi contrapposti di una impedenza (Zn) di predeterminato valore e rilevare tramite il primo circuito (6) il valore delle correnti presenti sulle seconde uscite (IT, IL);- commutare nuovamente tali uscite (R, T) tra i conduttori (A; B) della linea (3) e rilevare tramite il primo circuito (6) il valore delle correnti trasversali (It) e longitudinali (Il) della linea (3);- effettuare ad ogni rilevamento, tramite il secondo circuito (7), una codifica digitale dei valori rilevati trasmettendo inoltre alla centralina telefonica tali valori codificati.
