Timeslots containing SS7 signaling processed by the signaling processor on the DSI SPCI Board should not be included in the timeslot mask. Usually, the mask should be set to include all bearer (voice) timeslots but no signaling timeslots. Bit 0 (corresponding to timeslot 0 on the LIU) must not be set as timeslot 0 for an E1 interface contains synchronization information whilst timeslot 0 for a T1 interface does not exist.

As an example, for an E1 interface with SS7 signaling on timeslot 16, and the remaining 30 timeslots used for voice circuits, ts_mask should be set to value 0xfffefffe. For a T1 interface with signaling on timeslot 24, ts_mask must be set to value 0x00fffffe.

mode

This parameter controls how the CT bus channels are allocated. Usually, (mode=1) the first timeslot connected to the CT bus is connected to sc_channel and each subsequent timeslot that is selected is connected to the next CT bus channel. This allows maximum utilization of channels on the CT bus.

An alternative mode (mode=2) (only used if there is a specific requirement for it) associates (but does not necessarily connect) timeslot 0 on the LIU with sc_channel and subsequent timeslots on the LIU with subsequent CT bus channels. Connections are only made when the corresponding bit in the timeslot mask is set to 1. This mode of operation preserves the spacing between timeslots that was originally found on the T1/E1 interface but does result in a number of CT bus channels being not used.

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.
