Analog Embedded Voice

Embedded voice functionality is widely used in

Industrial applications today, typically implemented as

an analog intercom or telephone

• Campus emergency call centers

• Elevator emergency phone/intercom

• Hospital patient to nurse intercom

• Drive through restaurant order system

• Access point intercom

• Fire alarm public address system

• Gas (petrol) pump customer assistance intercom

• Operation room voice recording system

• Intruder alarm audio monitoring

77 Why VoIP?

VoIP can be used to replace current analog intercom and public

address systems, and to add voice support to new applications:

Advantages of using VoIP:

► Use existing (wired or wireless) network, no analog cables

► Better sound quality (avoiding analog noise)

► Ability to easily route call different locations:

• To offer support in different languages

• To offer 24/7 support

• To offer specialized support, e.g. technical

• Easily consolidate support at any location (worldwide)

► May be able to use existing application (

Cold

_Cold

Fire

®

) controller to minimize

additional cost

► Easy to record and archive calls on a computer system

(8)

What is VoIP?

VoIP - Voice over Internet Protocol

• A method of sending (audio) signals such as voice over a data network using TCP/IP

• Unlike the telephone network, it does not require a dedicated connection

• So far, mainly used as a low cost (or no cost) alternative to the traditional telephone,

but can be used for any voice communication and other signals

Digital Intercom Major Components

Voice only End-Point:

• “Push to connect”

intercom end-point

• Has no other functionality, except bi-

or uni-directional audio communication

Examples:

Fire alarm public address speaker

Emergency call point

House intercom

Application with Voice Functionality End-Point:

• Processor controls application, and intercom function

Examples:

Elevator car control panel with emergency intercom

Drive through restaurant order system with intercom and menu display

Security control panel with Public address system

Hospital bed controller with intercom to nurse’s station

Digital Intercom/VoIP SIP Server:

• Server for initiating VoIP communications

• Includes IP address “telephone book”

• May include gateway to public phone system

Example: Asterix

Soft DSP

(

GPP=General Purpose Processor

• Most low to mid range 32-bit processors do

not have sufficient performance for audio

(voice) processing.

• Most low to mid range DSPs

do not have

enough control capability to control an

application and manage a network connection.

This generally necessitates the use of both

a 32-bit CPU and a DSP for VoIP

applications

Most

Cold

Fire

implementations include the

Enhanced Multiply Accumulate (EMAC) giving

it the capability to process audio (VoIP),

control an application and manage a network

connection in a single (low-end) CPU

This results in a simpler system and lower

system cost
