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.
