Abstract

DISPOSITIVO DE SINCRONIZACION PARA AUTOCONMUTADOR NUMERICO (1), DE TIPO PRIVADO, QUE CONSTA DE UNA LOGICA DE CONTROL (4) Y UNAS INTERFACES ESPECIALIZADAS (9,8), MEDIANTE LAS CUALES ESTE AUTOCONMUTADOR SE ENLAZA, POR UNA PARTE, UNA PLURALIDAD DE TERMINALES DE ABONADO (2) POR UNOS ACCESOS (SO) Y, POR OTRA, A UNA RED DE TELECOMUNICACION (3) POR UNOS ACCESOS BASE (TO). EL AUTOCONMUTADOR CONSTA DE UN TEMPORIZADOR (6) QUE ASOCIA A UN OSCILADOR LOCAL DE FRENCUENCIA FIJA (7) CON UN CIRCUITO DE INMOVILIZACION DE FASE (32). EL DISPOSITIVO CONSTA DE ELEMENTOS DE CONMUTACION DE RELOJ APTOS PARA IMPONER AL CIRCUITO DE INMOVILIZACION DE FASE (32) DEL TEMPEORIZADOR (6) LAS PRIMERAS SEÑALES DE RELOJ PROVENIENTES DE LA RED (2) MEDIANTE UN ACCESO BASE (TO) ACTIVO Y DE LA INTERFAZ (8) ASOCIADA, DESDE EL MOMENTO DE LA PUESTA EN FASE APROXIMADA DE DICHAS PRIMERAS SEÑALES DE RELOJ FRENTE A LAS SEÑALES DE RELOJ DE SUSTITUCION PROPORCIONADAS POR EL TEMPORIZADOR (6) EN AUSENCIA DE LAS PRIMERAS SEÑALES.
