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

frame_format

Description

 

 

1E1 double frame (E1 only).

2E1 CRC4 multiframe (E1 only).

4

D3/D4 (Yellow alarm = bit 2 in each channel) (T1 only).

 

 

7

ESF (Yellow alarm in data link channel) (T1 only).

crc_mode

The CRC mode taken from the following table:

crc_mode

Description

 

 

1CRC generation disabled.

2CRC4 enabled (frame_format must be set to 2).

3CRC4 compatibility mode (frame_format must be set to 2).

4CRC6 enabled (frame_format must be set to 7).

build_out

Configurable line build out is not supported by the board, so the following fixed values must be used.

Build_out

Description

 

 

0Setting for E1 devices.

1Setting for T1 devices.

faw

The 8 bit value to be used for any E1 frame alignment word bit positions that are not modified by other options. This allows the spare bit designated "For International Use" to be set by the user when CRC4 mode is disabled. Valid values are 0x9b or 0x1b. When using T1, this parameter must be set to zero. [E1 default = 0x9b].

nfaw

The 8 bit value to be used for any E1 non-frame alignment word bit positions that are not modified by other options. Normally, this parameter is set to 0x9f for E1 operation and set to zero for T1.

ais_gen

The (initial) mode used to generate the Alarm Indication Signal (Blue Alarm) taken from the following table. The user may subsequently modify the setting of the outgoing signal using the LIU_MSG_CONTROL message.

ais_gen

Description

 

 

1Disabled - do not generate AIS / Blue alarm.

2Enabled - generate AIS / Blue alarm.

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.
