MTP 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.
6.1.4
Event 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.
