Abstract

PROCEDIMIENTO DE SINCRONIZACION ENTRE TERMINALES Y NODO CONMUTADOR EN SISTEMAS DE MODULACION POR IMPULSOS CODIFICADORES. LA INFORMACION A TRANSPORTAR SE DISPONE EN DIEZ TRAMAS DE BITIO, CADA UNA DE LAS CUALES PUEDE INCLUIR UNA COMBINACION EN CODIGO MIC DE OCHO BITS, MAS UN NOVENO BITIO UTILIZABLE PARA TRANSPORTAR LA INFORMACION DE SINCRONIZACION, Y UN DECIMO BITIO UTILIZABLE PARA TRANSPORTAR OTRA INFORMACION. A LA RECEPCION DE LA INFORMACION ENVIADA DURANTE BUSQUEDA DE SINCRONIZACION SE ALMACENA UNA TRAMA COMPLETA DE PALABRAS DE DIEZ BITIOS EN UN ALMACENAMIENTO INTERMEDIO, DONDE SE COMPRUEBA Y SE CAMBIA BAJO EL CONTROL DEL IMPULSO DE RELOJ. EL SISTEMA PROPORCIONA LA DETECCION INICIAL DE LA SINCRONIZACION EN AMBAS DIRECCIONES DEL BUCLE DE ABONADO DURANTE EL ESTABLECIMIENTO DE LA LLAMADA, LA MONITORIZACION DE LA SINCRONIZACION DURANTE DICHA LLAMADA, Y LA RECAPTURA DE LA SINCRONIZACION DESPUES DE UN FALLO DURANTE LA LLAMADA.
