Configurations
The Intel Dialogic D/82JCT-U PBX integration board
provides PBX integration with an industry-standard
CT Bus interface enabling access to CT Bus
supported complementary technologies (see Figure 1).
A dual-processor architecture consisting of a digital
signal processor (DSP) and a general-purpose
microprocessor handles all telephony signaling and
performs dual-tone multifunction (DTMF; touch-tone)
and audio/voice signal processing tasks. When used
with supported PBXs, the D/82JCT-U board provides
a flexible platform for developing integrated computer
telephony (CT) applications. Developers can port
current applications from D/42xx PBX integration
boards to D/82JCT-U boards with minimal software
modifications, and create more efficient applications
that are portable for use with multiple PBXs.
Use the D/82JCT-U board to build sophisticated,
multimedia communications systems that incorporate
capabilities such as voice processing, fax, TTS, and
ASR. The D/82JCT-U board shares a common hardware
and firmware architecture with other SCbus- and CT
Bus-based boards for maximum flexibility and scalability.
You can add features and grow the system while
protecting your investment in hardware and application
code. Applications can be ported to different PBX
integration solutions with only minimal modifications.

to eight boards can be configured in a single system.
The number of boards and channels supported
varies depending on the application, the operating
system, the amount of disk I/O required, the number
of CT Bus loads per board, and the host computer’s
CPU(s) and power supply.
The D/82JCT-U board can operate within a mixed
chassis containing PCI and ISA board-level products.
The board’s design incorporates an H.100 connector to
simplify the connection to next-generation CT Bus
products.
The D/82JCT-U board can access called number
identification for calls transferred from within the PBX,
access trunk identification for calls originating outside
the PBX, and control message waiting indicators for
message notification.
Downloaded firmware algorithms executed by
the onboard DSP provide variable voice coding at
24 Kb/s and 32 Kb/s adaptive differential pulse code
modulation (ADPCM), and 48 Kb/s and 64 Kb/s µ-law
or A-law pulse code modulation (PCM). Sampling rates
and coding methods are selectable on a channel-by-
channel basis. Applications may dynamically switch
sampling rate and coding method to optimize data
storage or voice quality as the need arises. These
firmware algorithms also provide reliable DTMF
detection, DTMF cut-through, and talk off/play off
suppression over a wide variety of telephone line
conditions.
