Abstract
PARA UNA FUTURA RED DE TRANSMISION DE NOTICIAS CON UNA JERARQUIA SINCRONICA DE SEÑALES DIGITALES, LA RECOMENDACION CCITT G. 709 PRESCRIBE QUE LAS SEÑALES DIGITALES DE JERARQUIA PLESIOCRONA SE ENCIERREN EN ELEMENTOS MULTIPLEX CON MARCOS DE IMPULSOS PRESCRITOS. POR ELLO, DICHOS MARCOS SE ESTRUCTURAN VERBALMENTE. SIN EMBARGO, EN ULTIMO EXTREMO, AL FINAL DE DETERMINADOS VOCABLOS, HAY QUE EMBUTIR MAS O MENOS BITS. EL INVENTO PROPORCIONA UN MULTIPLEXOR PARA CREAR UN TAL MARCO DE IMPULSOS Y UN DEMULTIPLEXOR PARA SEPARARLO Y ELIMINAR LOS BITS DE RELLENO. CON ELLO, EL MULTIPLEXOR TRABAJA VERBALMENTE Y TAL BIT (14, 15) DE UNA PALABRA DE RELLENO (Z), ACTUA COMO UN BIT DE LA PALABRA SIGUIENTE, COMO BYTES INICIALES DE LA SIGUIENTE PALABRA (W 1 + 1). DE LA MISMA MANERA TRABAJA TAMBIEN EL DEMULTIPLEXOR VERBALMENTE Y ELIMINA LOS BYTES DE RELLENO CONTENIDOS EN UNA PALABRA, MIENTRAS QUE AL ESCRIBIR LA PALABRA SUBSIGUIENTE, LOS TRANSFIERE A UNA MEMORIA ELASTICA. EN AMBOS CASOS ESTO SE REALIZA POR MEDIO DE UNDESPLAZAMIENTO CONTROLABLE DE DIRECCIONES DE LA MEMORIA.
