The D/120JCT-LS board is part of the new generation of Intel
analog PCI voice boards, offering enhanced capabilities that
an evolving computer telephony (CT) market segment demands.
This high-performance, scalable CT product offers a rich set
of advanced features that include new voice coders such as
G.726 and GSM, the de facto standard when complying with Voice
Profile for Internet Messaging (VPIM) standards. Features
such as software-based fax and speech recognition also let
you add robust application enhancements without additional
hardware. The D/120JCT-LS board also supports the international
standard, CTR21.
The 12-port D/120JCT-LS PCI analog voice processing board
is well positioned as a building block for developing communications
applications such as Web-enabled call centers, unified messaging,
and speech-enabled interactive media response (IMR) systems.
Configurations
D/120JCT-LS Configuration Diagram
The D/120JCT-LS board provides 12 channels of call processing
and loop start interfaces in a single PCI slot. The unique
dual-processor architecture, composed of DSPs and a general-purpose
microprocessor, handles all telephony signaling and performs
all DTMF (touch tone) and audio/voice signal processing tasks.
Downloaded Spring Ware firmware algorithms provide variable
voice coding at 24 and 32 Kb/s ADPCM, and 48 and 64 Kb/s µ-law
or A-law PCM. Sampling rates and coding methods are selectable
on a channel-by-channel basis. Applications can dynamically
switch the sampling rate and coding method to optimize data
storage or voice quality as the need arises. 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.
Offered as a software option, Global Dial Pulse Detection
(GDPD) converts rotary pulses to DTMF in countries that have
limited touch tone telephone service. Global DPD is also optimized
in several countries to provide superior dial pulse detection
and conversion.
Functional Description
The D/120JCT-LS board connects 12 analog loop start telephone
lines to 12 onboard call processing resources or to other
resources via the CT Bus.
This board provides:
- Interference suppression
- Ring and on-hook/off-hook signaling control
- Tone detection and generation
- Digitization and playback of voice files
The signals from the 12 loop start telephone lines connected
to the D/120JCT-LS board first pass through a telephone line
interface that provides transient protection and electromagnetic
interference (EMI) suppression (see daughterboard block diagram).
These telephone line interfaces use reliable, solid-state
hook switches (no mechanical contacts) and FCC-Part 68 Class
A ring voltage and Class B ring frequency circuitry. This
FCC-approved ring detector is less susceptible to spurious
rings created by random voltage fluctuations on the network.
Each interface also incorporates circuitry that protects against
high-voltage spikes and adverse network conditions and allows
applications to go off-hook any time during ring cadence without
damaging the board.
The telephone line interface applies the inbound signal including
the ring and on-hook/off-hook signals to analog/digital inputs
of a signal converter called a COder/DECoder (CODEC) that
samples and digitizes these signals. These digitized signals
are sent to a QSLAC chip where they are routed via the CT
Bus either to an onboard Motorola 56303 Onyx DSP* or to an
external resource on any of the 1024 CT Bus time slots. This
enables the application to reroute calls to any added resource,
such as speech recognition, facsimile, or text-to-speech (TTS).
Part of the D/120JCT-LS board's telephone interface includes
an on-hook audio path that detects Caller ID information.
Depending on the level of service offered by the local telephone
provider, Caller ID can include the date, time, caller's telephone
number, and the name of the person calling (in some enhanced
Caller ID environments). The on-hook audio path can also detect
touch tones while the line is on-hook. This capability lets
you use the D/120JCT-LS board behind PBXs that require on-hook
touch tone detection for their signaling. When the onboard
call processing resources are used, the network signals are
extracted and passed to the onboard control processor, which
can change channel status and communicate channel events to
the application via a shared RAM and the host PC PCI bus.

Daughterboard Block Diagram
The Motorola 56303 Onyx DSP processes the digitized voice
data based on Spring Ware firmware loaded in code/data RAM.
Each Motorola 56303 Onyx DSP performs the following signal
analysis and operations.
On the incoming data:
- Applies automatic gain control to compensate for variations
in the level of the incoming audio signal
- Applies an Adaptive Differential Pulse Code Modulation
(ADPCM), Pulse Code Modulation (PCM) algorithm, G.726 32
Kb/s coding, or GSM to compress the digitized voice and
save disk storage space
- Detects the presence of tones - DTMF, MF, or an application-defined,
single or dual tone
- Detects silence to determine whether the line is quiet
and the caller is not responding
For outbound data:
- Expands stored, compressed audio data for playback
- Adjusts the volume and rate of speed of playback upon
application or user request
- Generates tones - DTMF, MF, or any application-defined,
general-purpose tone
The dual-processor combination also performs outbound dialing
and call progress monitoring:
- Transmits an off-hook signal to the telephone network
- Dials out (makes an outbound call)
- Monitors and reports results: line busy or congested;
operator intercept; ring, no answer; or if the call is answered,
whether answered by a person, an answering machine, a facsimile,
or a modem.
When recording speech, the Motorola 56303 Onyx DSP can use
digitizing rates from 24 to 64 Kb/s as selected by the application
for the best speech quality and most efficient storage. The
digitizing rate is selected on a channel-by-channel basis
and can be changed each time a record or play function is
initiated. The DSP-processed speech is transmitted by the
control processor to the host PC for disk storage. The D/120JCT-LS
board can record incoming signals with the telephony interface
in either the high-impedance on-hook state or the normal off-hook
state. When replaying a stored file, the processor retrieves
the voice information from the host PC and passes it to the
Motorola 56303 Onyx DSP, which converts the file into digitized
voice. The DSP sends the digitized voice responses to the
CODEC, which is controlled by three QSLAC chips. The CODEC
converts the digitized voice into analog voice and sends the
voice response to the caller via the telephone line interface.
Although this product is capable of recording incoming signals
in an on-hook state, applications such as call logging should
use the D/160SC-LS-HiZ (ISA form factor), which is specifically
designed for analog high-impedance recording.
When the system is initialized, Spring Ware firmware is downloaded
from the host PC to the board. It controls all board operations.
Spring Ware firmware gives the board its intelligence and
enables easy feature enhancements and upgrades.
The onboard control processor controls all operations of
the D/120JCT-LS board via a local bus and interprets and executes
commands from the host PC. This processor handles real-time
events, manages data flow to the host PC to provide faster
system response time, reduces PC host processing demands,
processes DTMF and telephony signaling before passing them
to the application, and frees the Motorola 56303 Onyx DSPs
to perform signal processing. Communication between the processor
and the host PC is via shared RAM that acts as an input/output
buffer and thus increases the efficiency of disk file transfers.
This RAM interfaces to the host PC via the PCI bus. All operations
are interrupt-driven to meet the demands of real-time systems.
The Board Locator Technology circuit operates in conjunction
with a rotary switch that eliminates the need to set confusing
jumpers or DIP switches.
