6.1.3MTP Interface Messages

MTP Interface Messages allow signaling links to be activated and deactivated by the user and provide a mechanism for communication between the MTP3 module and the user part module (e.g., ISUP or TUP). In many cases, the user part module is an SS7 Protocol binary so the user does not need to handle the MTP-TRANSFER, MTP-PAUSE, MTP_RESUME & MTP-STATUS primitives as they pass directly between MTP3 and the user part module.

In the case that the user application is implementing the user part functionality, then the MTP primitives are applicable and these are documented in the MTP Interface messages section.

6.1.4Event Indication Messages

Event Indication Messages are the mechanism by which protocol and software error events are reported to the application. These messages are generated asynchronously by different modules within the stack.
