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.
