Figure 2. SWS Mode modules supported
1.7.2
Application Software
Application Development and the API used for this are covered in detail in the Dialogic® DSI Signaling
Servers SWS Application Programmer’s Manual.
Examples of application modules are supplied in source code form for use on the client host computer.
1.7.3
Fault Monitoring
The SWS is able to detect internal fault conditions and report these to the user. The internal faults are
combined with external events, to provide an alarm reporting function, which has several possible interfaces
to the user, and may be local or remote. For further information on alarm functions refer to Section 3.8,
“Alarms” on page 29.
1.7.3.1
Diagnostic Log Files
The SWS is able to generate several diagnostic log files for use in the event of an unexpected system restart.
The text files can be recovered from the unit using FTP.
1.7.4
Management Interface
A management interface is provided and may be accessed either via a VT100-compatible terminal or
remotely via telnet or SSH. This is used to request information on the status of signaling links and PCM ports.
The management interface also provides configuration information and activation of tracing. In addition a
some aspects of the system maybe set up using a web-based configuration interface.
1.7.5
IP Security
The SWS offers a number of security features for protection against unwarranted access on its IP interface. It
is recommended that the user enables the optional Password Protection feature on the Management
Interface port and on the FTP Server port.
For additional security, the SWS is equipped with Secure Shell (SSH) functionality, which supports the
tunneling of telnet and RSI traffic, as well as Secure FTP.
Unused ports are disabled to increase security against unintentional or malicious interference.
Additional security may be gained by separating management and signaling IP traffic. This can be achieved
by configuring specific Ethernet ports for traffic and utilizing other Ethernet ports for system management
information. Signaling IP traffic security between the SWS and its hosts can be further enhanced by
tunneling the IP traffic over SSH.
