Dialogic® D/4PCIUF and D/4PCIU4S Combined Media Boards

D4 PCI Boards

Field proven, high performance, 4 port media processing for analog; available in PCIe form factor and functions as an Analog Network Interface for Dialogic® Host Media Processing Software

The four-line Dialogic® D/4PCIUF and D/4PCIU4S combined media boards are ideal for small- and medium-sized enterprise computer telephony (CT) applications that require high-performance, cost aggressive media processing, but do not require the large-scale system sophistication of SCbus- or CT Bus-based products. The boards use the same application programming interface (API) as their predecessor (D/4PCI), making it easy to scale existing applications to take advantage of their power and features in a single PCI or PCI Express slot. The boards have improved voice quality and automatic gain control (AGC), so even the weakest telephone signals can be recorded and replayed with complete clarity. 

The D/4PCIUF (voice + fax) and D/4PCIU4S (voice + speech/CSP) give application developers a powerful platform for creating sophisticated interactive voice response (IVR) applications for the small- and medium-sized enterprise market segment. 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 and Benefits
Supports up to four channels of DSP-based onboard fax (D/4PCIUF only) Reduces the number of boards per system
Supports up to four channels of continuous speech processing (D/4PCIU4S only) A flexible speech processing technology, coupled with efficient drivers, off-loads critical real-time signal processing in speech-enabled applications to onboard DSPs. Reduces system latency, increases recognition accuracy, and improves overall system response time for speech solutions
Universal PCI edge-connector Compatibility with 3.3 V and 5.0 V bus signals enables deployment in a wide variety of PCI chassis from popular manufacturers
A variety of country-specific approvals Expands an application's ability to serve several global market segments
Supports G.726 and GSM coders Enables unified messaging applications that meet VPIM standards
Voice coding on a channel-by-channel basis Allows for optimal tradeoff in disk storage and voice quality
Half-size PCI form factor Enables cost-effective systems using the most up-to-date industry-standard chassis
