Dialogic DSI SPCI Network Interface Boards manual Following abbreviations are used in the table

4 Configuration and Operation

The following abbreviations are used in the table:

MTP2	Message Transfer Part – Level 2
MTP3	Message Transfer Part – Level 3
ISUP	ISDN User Part
TUP	Telephony User Part

In all cases, the process called ssds (SS7 Software Driver) must be run on the host computer. This handles message transfer between the host and the board using the device driver.

To define which protocol modules run on the host, edit the text file system.txt.

Run the program gctload, which reads the system configuration parameters from the file system.txt and starts up the selected processes bringing the system into operation.

For further details of gctload, refer to the Software Environment

Programmer’s Manual.

The following processes for use on the host are included in the distribution. All must be run on the host with the exception of s7_mgt, s7_log, and

s7_play, which are optional:

Table 8: Host Processes and Utilities

Name	Description
gctload	Process to initialize the system environment and start up all other related
	processes running on the host, deriving the configuration from a text file
	(system.txt).
ssds	Process to interface with the device driver for passing messages to and from
	the board(s) and for downloading software to the board(s).
tick_nt	Protocol timer process to send periodic “tick” notification to the tim_xxx
tick_lnx	process which in turn handles protocol timers.
tick_sol
tim_nt	Process to receive periodic tick notification from tick_xxx and handle protocol
tim_lnx	timers for all other processes.
tim_sol
s7_mgt	Process to perform single shot protocol configuration for all protocol modules,
	deriving the configuration parameters from a text file (config.txt). This process
	is optional. As an alternative to using it, the user may elect to perform
	protocol configuration by sending messages directly to the other modules in
	the system.
s7_log	Utility process to allow messages received from the protocol stack to be
	logged to a text file. This is useful for diagnostic purposes.
s7_play	Utility process used to generate messages from a text file and send them into
	the system.
