Dialogic® DSI SPCI Network Interface Boards Programmer's Manual Issue 5

1 Introduction

The range of Dialogic® DSI SPCI Network Interface Boards includes specialized T1/E1 SS7 signaling boards for use in PCI host computer systems. All boards offer a common interface to the application allowing applications to be easily ported between hardware architectures. This Programmer’s Manual relates to the low density Dialogic® DSI SPCI4 Network Interface Boards and Dialogic® DSI SPCI2S Network Interface Boards. Each low density board contains an embedded signaling processor capable of handling up to 4 SS7 signaling links and runs software which is downloaded onto the board at run time.

The boards provide a suitable hardware platform for running the Dialogic® DSI protocol for realizing Signaling System Number 7 signaling nodes. The boards can be used under any of the following operating systems: Windows® 2000, Windows® XP, Linux and Solaris. Throughout the remainder of this document the term "Windows®" may be used to collectively refer to the Windows® 2000 and the Windows® XP operating systems.

This document is the Dialogic® DSI SPCI Network Interface Boards Programmer’s Manual and it is targeted at system developers who choose to integrate the boards in a host computer and to develop applications that make use of the underlying SS7 protocol stack. The Programmer's Manual includes information on software installation, system configuration, protocol configuration, and operation of the board and SS7 software stack.

The Programmer's Manual should be used in conjunction with the appropriate Installation Guide and Regulatory Notice for the board, the Dialogic® Software Environment Programmer's Manual and the Programmer’s Manuals for the individual protocol modules as detailed in section 1.1.

High Density board ranges SS7HD and SS7MD are not covered by this manual, and users should refer instead to the relevant documentation package.

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.
