Abstract

PUESTO TELEFONICO QUE PERMITE LA TOMA EN LLAMADA Y EN RESPUESTA Y LA DISTENSION DE UNA LINEA TELEFONICA (L), CONECTADA AL MISMO, TANTO MEDIANTE UN PRIMER CONTROL PRODUCIDO POR UN PRIMER ORGANO DE CONMUTACION (CC), ACCIONADO POR EL COMBINADO DEL PUESTO, COMO MEDIANTE UN CONTROL PRODUCIDO POR UN SEGUNDO ORGANO DE CONMUTACION (14) ACCIONABLE INDEPENDIENTEMENTE DEL COMBINADO. LOS ORGANOS DE CONMUTACION (CC,14) PRODUCEN LOS CONTROLES MEDIANTE ELEMENTOS INDIVIDUALES DE PUESTA EN COMUNICACION (CC1,14A) QUE SE INSERTAN EN PARALELO EN UN CIRCUITO QUE ENLAZA, A TRAVES DE UN PRIMER DISPOSITIVO DE ALIMENTACION (15) DE UN MICROPROCESADOR (9) Y DE UN CONJUNTO (10) DE CIRCUITOS DE EXPLOTACION TELEFONICA DEL PUESTO, LAS BORNAS DE SALIDA DE UN PUENTE DE DIODOS (2) CUYAS BORNAS DE ENTRADA ESTAN ENLAZADAS A LOS DOS HILOS DE LINEA. UN SEGUNDO PUENTE DE DIODOS (6), UTILIZADO COMO REDIRECCIONADOR, ENLAZADO POR UNOS CONDENSADORES (7) A LA LINEA, EN PARALELO AL PRIMER PUENTE, ES APTO PARA ALIMENTAR AL MICROPROCESDOR Y AL CONJUNTO (10), MEDIANTE UN SEGUNDO DISPOSITIVO DE ALIMENTACION (8) A PARTIR DE SEÑALES ALTERNAS TRANSMITIDAS POR LA LINEA DURANTE LAS FASES DE TIMBRADO.
