DSI SS7MD Programmer’s Manual Issue 3
Chapter 6: Message Reference
This section describes the individual messages that may be sent to or received from a Dialogic® DSI SS7MD
Board. Some messages are sent by the user's application software, while others are sent by utility programs
such as the
s7_mgt protocol configuration utility.
Prior to sending any message to the board, the application should call the GCT_set_instance( ) library
function to select which board the message will be sent to. After receiving a message from the board, the
application should call the
GCT_get_instance( ) library function to determine which board the message
came from. These library functions are described in the Software Environment Programmer's Manual .
The various messages used are grouped in the following categories:
•
General Configuration Messages
•
Hardware Control Messages
•
Signaling Interface Messages
•
ATM Interface Messages
•
Q.SAAL Module
•
Event Indication Messages
•
Status Request Messages
Table 7, “Message Summary” on page 115 provides a summary of all messages. The message header for all
messages has the same general format. See the Message Format appendix in the Software Environment
Programmer’s Manual for more information.
