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 wellsuited 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.
Features Benefits
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
