INTERNATIONAL TELECOMMUNICATION UNION
ITU-T RECOMMENDATION SUMMARY
Rec. No. : F.435
Title : Message handling: electronic data interchange messaging
service
Study Group : I - Services
Version : New
Date of adoption : 1991
Notes :
Recommendation F.435 is one of a set of Recommendations for message
handling. The entire set provides a comprehensive specification for
message handling comprising any number of cooperating open-systems.
Message handling systems and services enable users to exchange
messages on a store-and-forward basis. A message submitted by one
user, the originator, is conveyed by the message transfer system
(MTS), the principal component of a larger message handling system
(MHS), and is subsequently delivered to one or more additional users,
the message's recipients.
An MHS comprises a variety of interconnected functional entities.
Message transfer agents (MTAs) cooperate to perform the
store-and-forward message transfer function. Message stores (MSs)
provide storage for messages and enable their submission, retrieval
and management. User agents (UAs) help users access MHS. Access units
(AUs) provide links to other communication systems and services of
various kinds (e.g., other telematic services, postal services).
Recommendation F.435 defines the overall system and service
description of the message handling application called EDI messaging.
