up_enable - User Part Enable

A 16 bit mask used to enable or disable reception of messages on a per user part basis. If bit N is set to 1, then messages for user part N are received by the signaling point.

For example, to enable the TUP User Part (Service indicator = 4) set the up_enable field to 0x0010, For ISUP (Service Indicator = 5), set the up_enable field to 0x0020. To use both TUP and ISUP, set up_enable to 0x0030.

linkn_flags - Per link flags

Bit 0 is set to 1 to force the use of the emergency proving period during link alignment. This bit is usually set to zero and uses the appropriate proving period according to Q.703.

Bit 1 is set to 1 to cause a signaling link test (in accordance with ITU-T Q.707) to be carried out before a link is put into service, or zero if a test is not required. This bit is usually set to 1.

Bit 2 is set to 1 to cause a signaling link test (in accordance with ITU-T Q.707) to be carried out every 30 seconds. This bit is usually set to 1, but is ignored if Bit 1 is set to zero.

Bit 8 is used to select the MTP2 error correction mode. It is set to 1 to select PCR (Preventive Cyclic Retransmission) operation, or zero for the Basic Method of Error Correction.

Bits 10 and 11 are used to select the data rate for the link as detailed below.

Note: When using a serial port, 56 kbps and 48 kbps operation is only supported when the clock is applied externally.

Bit 13 is only used when the link has been configured to run over a serial port (i.e., bit 14 is set). If set to 1, an external clock is used (Receive clock). If set to zero, an internal clock (Transmit clock) is used. If the link has not been configured to run over a serial port, this bit must be set to zero.

Bit 14 is set to 1 to use a serial port, rather than a PCM timeslot for this link. In this mode the stream and timeslot parameters for this link are ignored (and must be set to zero). If this bit is set to zero, the link uses the specified stream and timeslot. The serial port used by the signaling processors for each link is fixed, according to 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.
