4.1 Overview
This section describes the individual messages that may be sent to or received from a
Dialogic
®
SS7HD 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
• MTP Interface Messages
• Event Indication Messages
• Status Request Messages
Table 9, “Message Summary” on page 47 provides a summary of all messages. The
message header for all messages has the same general format. See the Message
Format appendix in the Dialogic
®
Distributed Signaling Interface Components -
Software Environment Programmer's Manual for more information.
