The
VFX/41JCT-LS is a four-port analog
converged communications board used for
developing global, enterprise
applications such as unified messaging,
IVR and contact centers. The VFX/41JCT-LS
supports voice, enhanced fax and
software-based speech recognition
processing in a single PCI slot,
providing four analog telephone
interface circuits for direct connection
to analog loop start lines.

The VFX/41JCT-LS board is a four-port
analog converged communications voice
and fax processing board ideal for
developers building enterprise unified
messaging and interactive voice/fax
response (IVR) applications for the
global market segment. The VFX/41JCT-LS
board provides four telephone line
interface circuits for direct connection
to analog loop start lines. A
dual-processor architecture, comprising
a digital signal processor (DSP) and a
general-purpose microprocessor, handles
all telephony signaling and performs
DTMF (touchtone) and audio/voice and fax
signal processing tasks.
The
VFX/41JCT-LS board, part of the
Intel?Dialogic? PCI product family,
conforms to the H.100 CT Bus standard.
The open architecture lets developers
build converged communications solutions
using products from multiple vendors.
And since multiple VFX/41JCT-LS boards
can be installed in a single PC chassis,
developers can build systems scaling up
to 32 ports.
Downloaded
Spring Ware firmware algorithms,
executed by the onboard DSP, provide
variable voice coding at 24 and 32 Kb/s
Adaptive Differential Pulse Code
Modulation (ADPCM), and 48 and 64 Kb/s
?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. Additional
coding algorithms (such as GSM and
G.726) are available for use in
applications that support the Voice
Profile for Internet Mail (VPIM)
standard.
Spring
Ware firmware also provides reliable
DTMF detection, DTMF cut-through, and
talk off/play off suppression over a
wide variety of telephone line
conditions.
Intel?
Dialogic?global dial pulse detection
(global DPD) algorithm, available as a
software option for the VFX/41JCT-LS
board, lets you use the board in
countries that have limited touchtone
telephone service. The global DPD
product can be optimized on a
country-by-country basis to provide
superior dial pulse detection.
With
all of these advanced features in a
half-size PCI board footprint, the VFX/41JCT-LS
board is perfect for client or small
server system development. The board
offers enhanced DSP power and memory
capacity that provide a base level of
performance for today's requirements as
well as the "head room" for
future application expansion via
software-based technologies.
The
VFX/41JCT-LS board features onboard DSP-based
fax, a rich set of fax features that
lets developers add fax functionality to
their communications applications.
Intel
voice and fax products offer a rich set
of advanced features, including
state-of-the-art DSP technology and
signal processing algorithms, for
building the core of any converged
communications system. With
industry-standard PCI bus expansion
boards developers can integrate Intel
Dialogic voice and fax products easily
and cost effectively into exactly the
type of system they require, with
superior performance.
