6 Message Reference

Description:

This message is sent to the DSI SPCI Board to configure the operating mode a line interface unit. All configuration parameters must be supplied in the message (it is not possible to modify individual operating parameters in isolation). On receipt of the message the board first verifies that the fitted hardware options support the requested operating mode and then initializes (or re-initializes) the line interface unit.

The confirmation message (if requested) indicates success by status of zero.

Parameter Description:

A description of the permitted parameter values are given below. When the DSI SPCI Board is initially configured all the line interfaces are initialized to a disabled condition.

liu_type

The physical type of interface according to the following table: (note that this must be selected by the user to be appropriate for the actual hardware fitted otherwise an error status is returned). The preferred method for configuring an E1 interface is to select liu_type=5.

liu_type

 

Description

1

Disabled (used to deactivate a LIU). In this mode the LIU does not produce

 

an output signal.

 

 

 

2

E1

75ohm unbalanced interface (for future use).

 

 

 

3

E1

120ohm balanced interface.

 

 

 

4

T1

 

 

 

 

5

E1

75ohm or 120ohm setting based on fitted hardware.

 

 

 

line_code

The line coding technique taken from the following table:

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.
