7.1.3LIU_SC_DRIVE Command

Syntax:

LIU_SC_DRIVE <board_id> <liu_id> <sc_channel>

 

<ts_mask> {<mode>}

Example:

LIU_SC_DRIVE 0 0 512 0xfffefffe

This command is used during initialization to set up a static switch path through the board between the Line Interface Unit (LIU) and the CT bus. It connects selected incoming voice timeslots from an T1/E1 LIU to a sequential block of channels on the CT bus and prepares the outgoing timeslots for subsequent use by the MVD_MSG_SC_LISTEN message.

<board_id>

The logical identity of the board in the range from 0 to one less than the number of boards supported.

<liu_id>

The identifier of the T1/E1 Line Interface Unit in the range 0 to one less than the number of LIUs fitted. This parameter can also be set to the special value 0x83 to select the signaling processor instead of an LIU. In this case timeslots 0 ... 3 in the ts_mask correspond to signaling processor 0…3.

Note that, for the SPCI2S, valid values for the LIU identifiers are 2 and 3.

<sc_channel>

The channel number of the first channel to be used on the CT bus. This must be in the range from 0 up to one less than the total number of channels on the CT bus.

<ts_mask>

A 32 bit timeslot mask where each bit position is set to 1 if the corresponding timeslot on the T1/E1 interface is required to be connected to the CT bus. The least significant bit (bit 0) represents timeslot 0. Each timeslot for which the corresponding bit is set in ts_mask is connected up to the CT bus; other timeslots are not affected in any way.

Timeslots containing SS7 signaling that are processed by the signaling processor on the 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 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 the value 0xfffefffe. For a T1 interface with signaling on timeslot 24, ts_mask should be set to the value 0x00fffffe.

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.
