Dialogic D120JCT-LS-EW / 884-594 12 Port Analog PCI / PCIe Media Board - Brand New

Dialogic® D/120JCT-LS Media Board
The Dialogic® D/120JCT-LS Media Board is a 12-port analog PCI or PCI Express board well-suited for developing advanced communications applications that require multimedia resources. This high performance, scalable product supports voice, fax, and software-based speech recognition processing in a single PCI or PCI Express slot, providing 12 analog telephone interface circuits for direct connection to analog loop start lines.

Dialogic® JCT Media Boards – including this model - can be used by developers to provide small- and medium-sized enterprise Computer Telephony (CT) applications that require high-performance voice and fax processing. Among the features and benefits of these boards, and other Dialogic® JCT Media Boards, are the following. They use Digital Signal Processor (DSP) voice processing technology, making them well suited for server-based CT systems under Windows and Linux. They also provide a powerful platform for creating sophisticated Interactive Voice Response (IVR) applications for the small and medium-sized enterprise market segment. Their Caller ID support lets applications, such as IVR, receive calling party information via a telephone trunk line; Caller ID is supported for North America (CLASS protocol), the United Kingdom (CLI protocol), and in Japan (CLIP protocol). Features such as fax and software-based speech recognition processing enable unified messaging applications. They also provide Automatic Gain Control (AGC), so even a weak telephone signal can be recorded and replayed with complete clarity.


Supports G.726 bit exact and GSM coders - Enables implementation of unified messaging applications that meet VPIM standards.

Supports Continuous Speech Processing (CSP) - Provides a flexible speech processing technology, which, when coupled with efficient drivers, off-loads critical real-time signal processing in speech-enabled applications to on-board DSPs. Reduces system latency, increases recognition accuracy, and improves overall system response time for high-density speech solutions.

A-law or μ-law voice coding at dynamically selectable data rates, 24 kbit/s to 64 kbit/s, selectable on a channel-by-channel basis - Allows for a beneficial tradeoff between disk storage and voice quality.

Telcordia CLASS, UK CLI, Japanese Caller ID, and other international protocols - Supports an international Caller ID capability via on-hook audio path.

A variety of country-specific approvals - Expands an application’s ability to serve several global market segments at no extra cost.

Separate models available with Universal PCI or PCI Express edge connector - Universal PCI form factor compatible with 3.3 V and 5.0 V bus signals; and PCI Express form factor compatible with x1 lane configuration or higher.

Supports up to four (4) channels of DSP-based on-board fax - Reduces the number of boards per system.
