64 ports.

Features and Benefits

Four independent voice processing ports in a single, half-size ISA slot supporting low- to medium-

density voice systems

Downloadable signal and call processing firmware, Spring Ware, facilitates feature enhancement and

provides field-proven performance based on over four million installed ports

C language application program interfaces (APIs) for MS-DOS*, Windows* 95, Windows NT*, OS/2*,

UNIX*, and Linux* shorten the development cycle to get applications to market faster

Application generators available from third-party providers

Configure multiple DIALOG/4 boards in a single PC for easy and cost-effective system expansion, and

to build scalable systems from four to 64 ports

Voice coding at dynamically selectable data rates, 24 Kb/s to 64 Kb/s, selectable on a channel-by-chan-

nel basis for optimal tradeoff in disk storage and voice quality

Enhanced telephone circuitry and automatic gain control (AGC) maintains recording quality over a wide

dynamic range

Perfect digit DTMF (touchtone) provides reliable detection during voice playback - lets callers “type-

ahead” through menus

Outbound call progress analyzes outgoing call status quickly and accurately

Supports PBXpert and PBXpert/32, complimentary utilities that simplify switch integration

Software Support

®

The Intel Dialogic DIALOG/4 board shares a common

hardware and firmware architecture with other Intel voice

boards for maximum flexibility and scalability. You can

easily add new features and/or expand the size of the

system while protecting your original investment in hard-

ware and application code. Applications can be ported to

lower or higher line-density platforms with minimal modifi-

cations.

®

The Intel Dialogic DIALOG/4 board is supported by

System Software and SDKs for MS-DOS*, Windows NT*,

Windows* 95, and Linux*. These packages contain a set

of tools for developing complex multichannel applications.

The DIALOG/4 board installs in IBM* PC XT*/AT* (ISA

bus) and compatible computers (PC platforms based on

®

the Intel386™, Intel486™, or Pentium processors). The

DIALOG/4 board provides everything required for building

integrated voice solutions scalable from four to 64 ports.

telephony signaling status, and instructs the line interface

Functional Description

®

The Intel Dialogic DIALOG/4 board uses a unique dual-

processor architecture that combines the signal processing

capabilities of a digital signal processor (DSP) with the

decision-making and data movement functionality of a

general-purpose 80C188 control microprocessor. This

dual-processor approach offloads many low-level decision-

making tasks from the host computer, enabling develop-

ment of more powerful applications.

The audio voice signal from the network is sent through a

bandpass filter, 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 the digitized signal to a

Motorola* DSP.

This architecture

■

handles real-time events

Based on Spring Ware firmware loaded in DSP RAM, the

DSP performs the following signal analysis and opera-

tions on this incoming data:

■

manages data flow to the host PC for faster system

response time

reduces host PC processing demands

■

processes DTMF and telephony signaling

frees the DSP to perform signal processing on the

incoming call

■

automatic gain control (AGC) to compensate for varia-

■

tions in the level of the incoming audio signal

■

applies an Adaptive Differential Pulse Code Modulation

(ADPCM) or Pulse Code Modulation (PCM) algorithm to

compress the digitized voice and save disk storage

space

Each of four loop start telephone line interfaces on the

DIALOG/4 board receives analog voice and telephony

signaling information from the telephone network (see

block diagram). Each line interface uses reliable, solid-

state hook switches (no mechanical contacts) and FCC

part 68 class B ring detection circuitry. This FCC-

approved ring detector is less susceptible to spurious

rings created by random voltage fluctuations on the net-

work. Each interface incorporates circuitry that protects

against high-voltage spikes and adverse network condi-

tions, letting applications go off-hook any time during ring

cadence without damaging the board.

■

detects the presence of tones — DTMF, MF, or an

application-defined single- or dual-frequency tone

■

silence detection to determine whether the line is quiet

and the caller is not responding

For outbound data, the DSP performs the following oper-

ations:

■

expands stored, compressed audio data for playback

■

adjusts the volume and rate of speed of playback upon

application or user request

Inbound telephony signaling (ring and loop current detec-

tion) are conditioned by the line interface and routed via a

control bus to the control processor. The control proces-

sor responds to these signals, informs the application of

■

generates tones — DTMF, MF, or any application-

defined general-purpose tone

The dual-processor combination also performs the follow-

ing outbound dialing and call progress monitoring:

The on-board microprocessor controls all operations of

the DIALOG/4 board via a local bus and interprets and

executes commands from the host PC. This

microprocessor

■

transmits an off-hook signal to the telephone network

■

dials out (makes an outbound call)

■

monitors and reports results

■

handles real-time events

— line busy or congested

— operator intercept

— ring, no answer

■

manages data flow to the host PC to provide faster

system response time

■

reduces PC host-processing demands

— or if the call is answered, whether answered by a

person, an answering machine, a facsimile machine,

or a modem

■

processes DTMF and telephony signals before passing

them to the application

frees the DSP to perform signal processing

■

When recording speech, the DSP can use different digi-

tizing 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 can be selected on a channel-

by-channel basis and can be changed each time a record

or play function is initiated. 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 digitized voice to

the CODEC to be converted into analog voice and then

to the line interface for transmission to the telephone net-

work.

Communications between this microprocessor and the

host PC is via the shared RAM that acts as an input/out-

put buffer, increasing the efficiency of disk file transfers.

This RAM interfaces to the host PC via the XT/AT bus. All

operations are interrupt-driven to meet the demands of

real-time systems. All DIALOG/4 boards installed in the

PC share the same interrupt line. When the system is ini-

tialized, Spring Ware firmware to control all board opera-

tions is downloaded from the host PC to the on-board

code/data RAM and DSP RAM. This downloadable

firmware gives the board all of its intelligence and enables

easy feature enhancement and upgrades.
