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

If the board is not licensed to run the requested software configuration, status value of 0xfe is returned.

Parameter Description:

flags - Global flags

Bit 0 is set to 1 to indicate that the user does not wish to use signaling software. This allows operation of the board without a software license button providing the board is used only for T1/E1 interface and switching purposes. If signaling software is required, then this bit must be set to zero.

Bit 9 is set to 1 to disable automatic MTP route configuration, in which case the user must send individual MTP Route Configuration messages for each destination. When set to zero, the board automatically configures an MTP route to each adjacent signaling point using the link set directly connected to the signaling point.

Bit 10 is reserved for future use and must be set to 1.

Bit 12 is set to 1 to cause all signaling links to be automatically activated. Usually, this bit is set to zero and the user sends individual MTP Link Activation requests to activate each link.

Bit 15 is set to 1 for diagnostic purposes to cause the results of internal board configuration to be passed to the host. When set, all confirmation messages generated internally on the board during the configuration sequence are sent to the module_id 0xdf on the host.

All other bits are reserved for future use and must be set to zero.

l1_flags - level 1 flags

Bit 0 controls the reference source used for on-board clocks when acting as CT bus Primary Master. If set to 1, the clock is recovered from one of the line interfaces. If set to zero, the on-board clock oscillator is used.

Bit 6 and 7 together select the initial CT bus clocking mode as shown in the following table. The clocking mode can be modified subsequently and dynamically using the MVD_MSG_CNFCLOCK message.

Bit 7

Bit 6

CT bus clocking mode

0

0

The CT bus interface is disabled - The board is electrically

 

 

isolated from the other boards using the CT bus. The CT bus

 

 

connection commands may still be used, but the connections made

 

 

are only visible to this board. The on-board clocks are synchronized

 

 

to the source selected by bit 0 of this flags parameter.

 

 

 

 

0

1

Primary Master, A Channel - The board drives CT bus clock set A

 

 

using the clock source selected by bit 0 of this flags parameter.

 

 

 

 

1

0

Secondary Master, B Channel - The board is configured to drive

 

 

clock set B in Secondary Master mode. The on-board clocks are

 

 

synchronized to the CT bus clock set A. It will automatically switch

 

 

to become Primary Master if the board driving clock set A fails.

 

 

 

 

1

1

Slave, initially A Channel – The board uses the CT bus clocks,

 

 

which must be generated by another board on the CT bus. Initially

 

 

the board recovers from clock set A, though will switch over

 

 

automatically to recover from clock set B if set A fails.

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.
