4.1 Overview
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 Interface Messages
Event Indication Messages
Status Request Messages
