This ITU-T Recommendation defines the technical specification of a session layer protocol module called Electronic Communications Interactive Agent. This may be used as an interface reference point in a TMN model for the asynchronous exchange of data between peer application entities. The Interactive Agent (IA) supports the exchange of near real time Electronic Data Interchange (EDIFACT or ASC X12 EDI) transactions. In addition, this ITU-T Recommendation defines the architecture, design, structure, and process-flow for both normal[1]and high priority[2] business functions utilizing Transport Layer Security (TLS).
