ITU-T X.440-1999 信息传递系统:语音信息系统

This revision of Recommendation X.440 is a consolidation of Recommendation X.440 (09/92) and Amendment 1 (11/95). This Recommendation defines an OSI Message Handling System protocol that is intended to be used in the exchange of voice encoded messages in a store and forward manner as specified in Recommendation F.440. The protocol specified in this Recommendation is based on the ITU-T X.400-series Recommendations and ISO/IEC 10021 Parts 1 to 7.

ITU-T Z.323 SPANISH-1988 人机交互

This Recommendation describes howinteractions should take place between the user and the system from alogical viewpoint. It describes how an effective man-machine interface should appear to the user when utilizing thecapabilities of VDTs as described in Recommendation Z.322. This Recommendation supersedes RecommendationsZ.311-Z.317 for interfaces based on VDTs, referencing parts of them where appropriate. Specific human factorguidelines are included within the appropriate divisions of the text.
