4 Configuration and Operation

4.1Overview

Prior to performing software configuration, the user should gain an appreciation of:

the flexibility of the protocol stack,

the run-time options that exist,

the mechanisms used to select particular features.

This section gives an overview of these aspects.

The user should also consult the Software Environment Programmer’s Manual, which describes the basic principles of modules and message passing.

4.1.1System Structure

The SS7 software running on the board communicates with an application running on the main CPU of the host computer. The physical interface to the board uses the PCI bus. All communication with the board is handled by a device driver and the messages passing to and from the board are managed by a process (ssds) that runs on the host computer.

In addition to running the application on the host computer, the user may, depending on the size of the overall system and the network topology, elect to also run some of the SS7 protocol modules on the host. In such cases, the interface between the application and the SS7 protocol software remains identical. This allows for easy migration from a small system contained on a single board to a large system distributed over many boards with minimal changes to the application. When a protocol is run on the host, it is necessary to purchase and install a Software License on the host.

The table illustrates some possible system configurations for a telephony system.

DSI SPCI Network Interface Boards specifications

Dialogic DSI SPCI Network Interface Boards are highly advanced and versatile communication solutions tailored for the demands of modern telephony and multimedia applications. These boards are designed to efficiently process voice, data, and signaling, making them an essential component for businesses looking to enhance their communication capabilities.

One of the standout features of the Dialogic DSI SPCI boards is their ability to handle multiple telephony protocols. This flexibility allows users to connect to various network types, whether PSTN, VoIP, or legacy systems, ensuring seamless interoperability. The boards support industry-standard protocols such as ISDN, SS7, and SIP, enabling integrated communication across diverse platforms.

The technology behind the Dialogic DSI SPCI boards incorporates state-of-the-art digital signal processing (DSP). This powerful DSP architecture provides efficient encoding and decoding of voice and video signals, leading to enhanced call quality and reduced latency. Moreover, the DSP technology supports advanced codecs, ensuring that voice communication is clear and intelligible, even over bandwidth-limited connections.

Another significant characteristic of these boards is their scalability. Organizations can start with a single board and expand their telecommunication capabilities as their needs grow. This scalability makes them suitable for a wide range of applications, from small businesses to large enterprises, allowing for easy integration into existing infrastructures.

In addition to their powerful processing capabilities, Dialogic DSI SPCI boards also prioritize reliability and robustness. They are designed with a focus on fault tolerance, ensuring that telephony services remain uninterrupted even in the event of hardware failure. This resilience is critical for mission-critical applications where downtime can lead to significant revenue loss.

Furthermore, the boards feature extensive application development support. Developers can leverage the Dialogic API and various development kits to create custom telephony applications that meet specific business requirements. This programmability opens the door to innovative solutions, such as interactive voice response (IVR) systems, automated call distribution (ACD), and customer relationship management (CRM) integration.

In summary, Dialogic DSI SPCI Network Interface Boards are a cornerstone for organizations looking to innovate their telecommunication systems. With their support for multiple protocols, advanced DSP technology, scalability, reliability, and development support, these boards empower businesses to optimize their communication strategies and adapt to the evolving landscape of digital interaction.
