Dialogic DSI SPCI Network Interface Boards manual

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

To configure the board using individual messages, the following sequence must be used. (The format of all the messages is described in Section 5 of this manual):

1)Build and send an SSD Reset Message.

This contains the parameters to initialize the ssds module.

2)Build and send a Board Reset Message for each board.

This includes the id of the board and the name of the Code File. It causes the board to be reset and the Code File downloaded.

3)Wait until a Board Status Message is received (for each board). Inspect the status field to determine whether the reset was successful. On failure you should check carefully the parameters and try again. On success continue to the next step.

4)Build and send a Board Configuration Message. This contains all mandatory protocol configuration parameters for the Message Transfer Part (MTP)

(such as point codes, physical link settings and MTP configuration parameters).

5)Wait until a Board Configuration Confirmation Message is received. Inspect the status field which is zero on success.

On failure re-check the configuration parameters and go back to resetting the board.

6)Optionally, send LIU Configuration Request Messages for each T1/E1 line interface unit on the board to configure the appropriate operating mode.

Ensure the status field is zero in the confirmation message.

7)Optionally, send MTP Config Route Messages for any remote signaling points (other than adjacent signaling points. The route configuration for adjacent signaling points is automatically set up using the board configuration message). Ensure the status field is zero in the confirmation message.

8)If a user part (e.g., ISUP or TUP) is included in the Code File, build and send the per-module configuration message (as defined in the Programmer’s Manual for the User Part Module). Ensure the status field is zero in the confirmation message.

9)If a user part is included, build and send circuit group configuration messages for each circuit group (as defined in the Programmer’s Manual for the User Part Module). Ensure the status field is zero in the confirmation message.

10)The protocol stack is now configured ready for use (the same as if the configuration utility s7_mgt had been used). The user must send an MTP Activate Signaling Link message for each signaling link to start up SS7 operation.

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.
