Abstract

UN DISPOSITIVO DE RESINCRONISMO PARA USO EN UN DEMULTIPLEXADOR DE UN SISTEMA DE TRANSMISION DE DATOS SDH UTILIZA LOS DATOS DE JUSTIFICACION DE LOS BITS, Y NO UTILIZA LOS DATOS DE PUNTERO, PARA MODIFICAR UNA SEÑAL DE RELOJ RECUPERADA Y GENERAR UNA SEÑAL DE RELOJ CON PROPOSITOS DE RESINCRONIZACION. LA INVENCION SE USA ESPECIALMENTE PARA PERMITIR QUE LOS USUARIOS DE TERCERAS LINEAS TRANSPORTEN LOS DATOS DE SINCRONISMO DE VELOCIDAD PRIMARIA A TRAVES DE UNA RED SDH.
