6.4 Signaling Interface Messages
Signaling 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 (for example, ISUP, TUP
or SCCP). In many cases, the user part module is an Dialogic
®
DSI Protocol Stack so the user does not need
to handle the MTP 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, the MTP primitives are
applicable. See the MTP2 Programmer’s Manual and the MTP3 Programmer’s Manual for more information.
The messages in the Signaling interface category include:
•
SS7_MSG_CONFIG - MTP2 Link Configuration Request
•
API_MSG_RX_IND - Received Data Indication
•
API_MSG_RX_INDT - Timestamped Incoming Signaling Unit Indication
•
API_MSG_TX_REQ - MTP2 Transmission Request
•
GEN_MSG_MOD_IDENT - Module Identification Request
