Abstract

MULTIPLICADOR DE LINEA TELEFONICA. TIENE POR OBJETO PERMITIR LA UTILIZACION DE UN UNICO PAR FISICO (5) DE CONEXION DE ABONADOS CON UNA CENTRAL TELEFONICA (1), POR CUATRO ABONADOS (4); PARA LO QUE CUENTA CON UNA UNIDAD DE CENTRAL (2) Y UNA UNIDAD DE ABONADOS (3) QUE SE CONECTAN A LOS CUATRO ABONADOS Y A LA UNIDAD CENTRAL TELEFONICA RESPECTIVAMENTE A TRAVES DEL UNICO PAR DE ENLACE (5). SE CARACTERIZA PORQUE LA UNIDAD DE CENTRAL (2) APLICA UN NIVEL DE TELEALIMENTACION ALTO UNICAMENTE CUANDO ESTA ESTABLECIDO EL ENLACE ENTRE AMBAS UNIDADES. EN OTRO CASO, LA TENSION APLICADA SOBRE EL PAR ES BAJA LO QUE REPRESENTA UNA SEGURIDAD PARA UN OPERARIO. ADICIONALMENTE SE DETECTAN LAS DERIVACIONES A TIERRA DEL PAR DE ENLACE, INTERRUMPIENDOSE EN ESTE CASO LA APLICACION DE TELEALIMENTACION CONSTITUYENDO UN MEDIO DE SEGURIDAD MAS PARA EL OPERARIO. CADA UNA DE LAS UNIDADES REALIZA COMPROBACIONES CONSTANTES DEL FUNCIONAMIENTO DE SUS ORGANOS INTERNOS, ASI COMO DEL ESTADO DE LOS PARES. A PARTIR DE ESTAS PRUEBAS,LA UNIDAD DE CENTRAL (2) ELABORA UNOS DIAGNOSTICOS QUE SE ENVIAN A UN CENTRO DE CONTROL A TRAVES DE UNA RED DE SUPERVISION. ESTO FACILITA ENORMEMENTE LA DETECCION Y REPARACION DE AVERIAS.TELEPHONE LINE MULTIPLIER. PURPOSE TO ALLOW THE USE OF A SINGLE PHYSICAL PAIR (5) TO CONNECT SUBSCRIBERS WITH A TELEPHONE CENTER (1), BY FOUR SUBSCRIBERS (4); FOR WHICH IT HAS A UNIT OF CENTRAL (2) AND A UNIT OF SUBSCRIBERS (3) THAT CONNECT TO THE FOUR SUBSCRIBERS AND TO THE CENTRAL TELEPHONE UNIT RESPECTIVELY THROUGH THE SINGLE LINKING PAIR (5). IT IS CHARACTERIZED BECAUSE THE CENTRAL UNIT (2) APPLIES A HIGH LEVEL OF TELEALIMENTACION ONLY WHEN THE LINK BETWEEN BOTH UNITS IS ESTABLISHED. IN ANOTHER CASE, THE VOLTAGE APPLIED ON THE TORQUE IS LOW WHICH REPRESENTS SAFETY FOR AN OPERATOR. ADDITIONALLY, THE GROUND COUPLING GROUNDS ARE DETECTED, IN THIS CASE THE TELE-SUPPLY APPLICATION IS DISCONTINUED CONSTITUTING ANOTHER SAFETY MEANS FOR THE OPERATOR. EACH OF THE UNITS CONSTANTLY CHECKS THE FUNCTIONING OF ITS INTERNAL BODIES, AS WELL AS THE STATE OF THE COUPLE. FROM THESE TESTS, THE CENTRAL UNIT (2) DEVELOPS SOME DIAGNOSES THAT ARE SENT TO A CONTROL CENTER THROUGH A SUPERVISION NETWORK. THIS ENTIRELY FACILITATES THE DETECTION AND REPAIR OF FAULTS.
