Abstract
EN SISTEMAS DE TRANSMISION DE MENSAJES DIGITALES, EN DONDE SE UTILIZA PARA LA SINCRONIZACION UN INDICADOR (SSM) DE CALIDAD SINCRONIZACION, PUEDEN GENERARSE ENTRE OTRAS COSAS LAZOS (TIMING LOOPS) DE SINCRONIZACION. PARA EVITAR LAZOS DE SINCRONIZACION DE ESTE TIPO, SE DA A CONOCER UN SISTEMA DE TRANSMISION DE MENSAJES DIGITAL SINCRONO CON ELEMENTOS (NE11...NE33) DE RED, DONDE SE DISPONE DE DOS CLASES (TOP, BOTTOM) PARA LOS EQUIPOS (S1,....Sx,..., Sx+i) DE AJUSTE DE PASO.
