Abstract

L'INVENTION CONCERNE UN PROCEDE POUR PRODUIRE UN SIGNAL DE CONTROLE POUR LA LOCALISATION DE DEFAUTS. SELON CE PROCEDE MIS EN OEUVRE DANS UN APPAREIL TERMINAL DE LIGNE (DECODEUR DEC 1, BROUILLEUR SCR ET CONVERTISSEUR DE CODE ALPHABETIQUE), LA LONGUEUR DE LA PERIODE DU SIGNAL DE CONTROLE EST CHOISIE DE TELLE MANIERE QUE LE PLUS PETIT COMMUN MULTIPLE DES LONGUEURS DE LA PERIODE DE TRAME DU SYSTEME DE TRANSMISSION D'INFORMATIONS DE LA PERIODE DU BROUILLEUR ET DE LA PERIODE DU SIGNAL DE CONTROLE EST AUSSI VOISIN QUE POSSIBLE DE LA LONGUEUR DE LA PERIODE D'UN SIGNAL DE LOCALISATION EMIS POUR LA LOCALISATION DES DEFAUTS, LE MOT CARACTERISTIQUE DE TRAME DU SYSTEME ETANT UTILISE POUR LE CONTROLE ET LE DECLENCHEMENT DU DISPOSITIF DE BROUILLAGE ET N'ETANT CONTENU QU'UNE FOIS DANS LA PERIODE DE TRAME. APPLICATION NOTAMMENT AUX SYSTEMES DE TRANSMISSION PCM.The invention relates to a method for generating a control signal for the location of faults. ACCORDING TO THIS PROCESS, IMPLEMENTED IN A LINE TERMINAL APPARATUS (DECODER DEC 1, SCR JAMMER AND ALPHABETICAL CODE CONVERTER), THE LENGTH OF THE MONITORING SIGNAL PERIOD IS SELECTED IN SUCH A WAY THAT THE SMALLEST COMMON MULTIPLE OF LENGTHS FRAME PERIOD OF THE INFORMATION TRANSMISSION SYSTEM OF THE INTERRUPT PERIOD AND THE CONTROL SIGNAL PERIOD IS AS NEAR AS POSSIBLE TO THE LENGTH OF THE PERIOD OF A LOCATION SIGNAL ISSUED FOR FAULT LOCATION, THE CHARACTERISTIC WORD FRAME OF THE SYSTEM BEING USED FOR THE CONTROL AND TRIP OF THE JAMMING DEVICE AND BEING CONTAINED ONLY ONCE IN THE FRAME PERIOD. APPLICATION IN PARTICULAR TO PCM TRANSMISSION SYSTEMS.
