Abstract

EN SISTEMAS DE COMUNICACION ELECTRONICA, LAS NEGOCIACIONES SE REALIZAN ENTRE DOS PIEZAS DE APARATOS (POR EJ, MODENES) PARA ASEGURAR LA COMPATIBILIDAD TECNICA DURANTE LA SUBSECUENTE TRANSMISION DE DATOS. EN VEZ DE REALIZAR CONTROLES DE SEGURIDAD DE LA FORMA CONOCIDA DESPUES DE QUE SE HAN TERMINADO LAS NEGOCIACIONES (POR EJ., UN CODIGO DE ACCESO O CODIGO DE IDENTIFICACION), LA INVENCION ENSEÑA QUE LAS NEGOCIACIONES POR SI MISMAS DEBEN DE SER POR ENCARGO PARA INCLUIR CONTROLES DE SEGURIDAD. POR EJEMPLO DURANTE LAS NEGOCIACIONES ENTRE UN MODEN DE LLAMADA Y UN MODEM DE RESPUESTA, EL MODEM DE LLAMADA INCLUYE UNA "PRIMERA INDICACION" EN LAS NEGOCIACIONES. EL MODEM DE RESPUESTA DETECTA LA "PRIMERA INDICACION" Y PERMITE AL MODEM DE LLAMADA TENER ACCESO A DATOS DE ACCESO RESTRINGIDO DURANTE LA TRANSMISION DE DATOS DESPUES DE QUE HAN TERMINADO LAS NEGOCIACIONES. LA "PRIMERA INDICACION" PUEDE COMPRENDER UN SEGMENTO DE NEGOCIACION CON UNA LONGITUD PRECISA Y/O CONTENIENDO UN CODIGO INCLUIDO. EL MODEM DERESPUESTA PUEDE INCLUIR UNA "SEGUNDA INDICACION" EN LAS NEGOCIACIONES PARA DISPARAR EL MODEM DE LLAMADA PARA PRODUCIR LA "PRIMERA INDICACION". TAMBIEN EL MODEM DE LLAMADA PUEDE INCLUIR UNA "TERCERA INDICACION" EN LAS NEGOCIACIONES DESPUES DE LA "PRIMERA INDICACION" PARA IDENTIFICAR CON MAS PRECISION O UNICAMENTE EL MODEM DE LLAMADA.
