ITU-T X.420 (06/1999)

Tecnología de la información – Sistemas de tratamiento de mensajes: Sistema de mensajería interpersonal

Esta Recomendación | Norma Internacional se ha revisado a fin de utilizar el almacenamiento de mensajes mejorado definido en la Rec. UIT-T X.413 | ISO/CEI 10021-5. También añade definiciones de partes de cuerpo para voz, informes y notificaciones. Se ha revisado completamente la ASN.1 para utilizar las nuevas Recomendaciones UIT-T X.680 | ISO/CEI 8824-1 y UIT-T X.880 | ISO/CEI 13712-1, al tiempo que se preserva una compatibilidad total con los protocolos IPM de 1988 y 1992. Se han corregido numerosos defectos. Esta versión incluye definiciones de un conjunto ampliado de valores enteros ASN.1 para códigos de diagnóstico de errores de seguridad IPM.
