JCT Media Boards can be used by developers to provide
small- and medium-sized enterprise Computer Telephony (CT)
applications that require high-performance, cost-aggressive voice
and fax 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 (Dialogic
®
D/4PCI Media Board), 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 a weak telephone signal can be recorded and replayed with complete clarity.

D/4PCIU4S Media Board
Features 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)
Provides a flexible speech processing technology, which wnen
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.
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 enabling deployment in a wide variety of PCI chassis from
popular manufacturers; PCI Express form factor compatible with
1x slots (x1 or higher compatible) also available
A variety of country-specific approvals Expands an application’s ability to serve several global market
segments
Supports G.726 and GSM coders Implements unified messaging applications that meet VPIM
standards
Voice coding on a channel-by-channel basis Allows for optimal tradeoff between disk storage and voice quality
Half-size PCI or PCI Express form factor Build cost-effective systems using the most up-to-date industry-
standard chassis
The D/4PCIUF (voice and fax) and D/4PCIU4S (voice and speech/CSP) use Digital Signal Processor (DSP) voice
processing technology, making it well-suited for server-based CT systems under Windows
®
and Linux. These boards
provide 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).
