perfect for client or small server system development.
The boards offer enhanced DSP power and memory
capacity that provides a base level of performance for
today’s requirements, as well as the “head room” for
future application expansion via software-based
technologies.
The D/4PCIU and D/4PCIUF boards use the latest digital signal processor (DSP) voice processing technology, making it ideal for server-based CT systems —
particularly under Windows* and Linux* operating
systems. The D/4PCIU and D/4PCIUF voice and fax

and Windows 2000, as well as Linux application
developers, 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).

applications.
Functional Description
The D/4PCIU and D/4PCIUF voice and fax processing
boards build on a dual-processor architecture that
combines the signal processing capabilities of a DSP
with the decision-making and data movement
functionality of a general-purpose control microprocessor by using faster processors and considerably
more memory. This dual-processor approach offloads
many low-level decision-making tasks from the host
computer, thus enabling easier development of more
powerful applications. This architecture handles
real-time events, manages data flow to the host PC for
faster system response time, reduces host PC
processing demands, processes dual tone
multifrequency (DTMF) and telephony signaling, and
frees the DSP to perform signal processing on the
incoming call.
Each of the four loop start interfaces receives analog
voice and telephony signaling information from the
telephone network (see Figure 2). Each telephone line
interface uses reliable, solid-state hook switches (no
mechanical contacts), and provides an on-hook path
for ring detection. Each interface also incorporates
circuitry that protects against high-voltage spikes and
adverse network conditions and lets applications go
off-hook any time during ring cadence without
damaging the board.
Part of the telephone interface for the D/4PCIU and
D/4PCIUF boards 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 in some enhanced Caller ID
environments, the name of the person calling. The
on-hook audio path can also detect touch-tones while
the line is on-hook. This capability lets the boards
operate behind private branch exchanges (PBXs) that
require on-hook touch-tone detection for their signaling.
Inbound telephony signaling (ring detection and loop
current detection) are conditioned by the line interface
and routed via a control bus to the control processor.
The control processor responds to these signals,
informs the application of telephony signaling status,
and instructs the line interface to transmit outbound
signaling (on-hook/off-hook) to the telephone network.
The audio voice signal from the network is bandpass
filtered and conditioned by the line interface and then
applied to a COder/DECoder (CODEC) circuit. The
CODEC filters, samples, and digitizes the inbound
analog audio signal and passes this digitized audio
signal to a Motorola* DSP.
Based on Spring Ware firmware loaded in DSP RAM,

Datasheet Intel® Dialogic® D/4PCIU Voice Board and Intel® Dialogic® D/4PCIUF Combined Media Board
the DSP performs the following signal analysis and
operations on this incoming data:
■ uses AGC to compensate for variations in the level of
the incoming audio signal. The D/4PCIU and
D/4PCIUF boards also include special circuitry to
detect and amplify extremely weak line signals due
to harsh telephone line conditions or back-to-back
local loops often found in 800 (toll-free) service environments.
■
applies an adaptive differential pulse code modulation (ADPCM) or pulse code modulation (PCM) algorithm to compress the digitized voice and save disk
storage space
■
detects the presence of tones — DTMF, MF, or an
application-defined single- or dual-frequency tone
■
uses silence detection to determine when the line is
quiet and the caller is not responding
For outbound data, the DSP performs the following
operations:
■ 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 applicationdefined general-purpose tone
The dual-processor combination also performs the
following outbound dialing and call progress
monitoring:
■ transmits an off-hook signal to the telephone network
4
■
dials out (places 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
machine, or a modem
When recording speech, the DSP can use different
digitizing rates from 24 Kb/s 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 popular
11 kHz, 8-bit linear multimedia WAVE format is also
supported on the D/4PCIU and D/4PCIUF voice and
fax boards.
Outbound processing is the reverse of inbound
processing. The DSP processed speech is transmitted
by the control microprocessor to the host PC for disk
storage. When replaying a stored file, the microprocessor receives the voice information from the host PC and
passes it to the DSP, which converts the file into
digitized voice. The DSP sends the digitized voice to
the CODEC to be converted into analog voice and then
to the line interface for transmission to the telephone
network.
The on-board microprocessor controls all operations of
the D/4PCIU and D/4PCIUF boards via a local bus and
interprets and executes commands from the host PC.
This microprocessor 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
DSP to perform signal processing. Communications
between this microprocessor and the host PC is via the
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. All D/4PCIU and D/4PCIUF boards
installed in the PC share the same interrupt line. When
the system is initialized, Spring Ware firmware is
downloaded from the host PC to the on-board
code/data RAM and DSP RAM to control all board
operations. This downloadable firmware gives the
board all of its intelligence and enables easy feature
enhancement and upgrades.
