Abstract

Conversor de reloj de 2.048 MHz a señal de línea a 2.048 Mbit/s. El conversar de reloj de 2.048 MHz a señal de línea de 2.048 Mbit/s, es un equipo diseñado para generar una trama de señal PCM a 2.048 Mbit/s a partir de un reloj de 2.048 MHz de entrada. La señal de trama PCM con Código de Redundancia Cíclica (CRC) que crea este equipo, aunque no lleva tráfico de datos sí que lleva incluida la información de fase del reloj de entrada. Dispone de ocho salidas de datos sincronizadas en fase con el reloj de entrada de 2.048 MHz. Tanto la interfaz de entrada como las ocho tramas de salida PCM se ajustan a las recomendaciones G.703, G.704 y G.706 de la UIT-T. Además dispone de una señal de alarma que se activa en el caso que desaparezca la señal de reloj de 2.048 MHz de la entrada del conversor.
