Standard ECMA-346 Private integrated services network (PISN) – specification, functional model and information flows – message centre monitoring and mailbox identification supplementary services (MCM-SD / MID-SD)

Summary

This standard specifies the supplementary services Message Centre Monitoring (MCM) and Mailbox Identification (MID) for Private Integrated Services Networks (PISNs). MCM informs a user about the status and changes of messages in their mailbox, including new messages and changes due to retrieval or deletion. The service allows for activation, deactivation, and interrogation of monitoring for different message types, with information delivered in either complete or compressed forms. MID enables the identification of a specific mailbox and user authentication when multiple mailboxes exist. The standard includes stage 1 (user perspective) and stage 2 (functional entities and information flows) specifications, requiring conformity with future stage 3 standards that cover signaling protocols and equipment behavior.
