4 Message Reference

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
