C-DOT Interactive Voice Response System

Hardware Architecture

Centre for Development of Telematics


NEED FOR DEVELOPMENT REQUIREMENT FROM THE CUSTOMER MINIMUM HARDWARE EFFORT LOW COST OF DEVELOPMENT LARGE VOLUMES


OTHER OBJECTIVES TO DEVELOP A RANGE OF CTI BASED PRODUCTS AND

APPLICATIONS ON THE SAME HARDWARE PLATFORM BY MAKING IT APPLICATION INDEPENDENT.


DEFINITION AN IVRS IS AN APPLICATION OF COMPUTER TELEPHONY

INTEGRATION (CTI) BUSINESS APPLICATION CAN BE CREATED ON THIS

WHICH INVOLVES COMPUTING AND TELEPHONY IVRS MERGES THE FUNCTIONALITIES OF

COMPUTING : like data STORING,ACCESSING,MANIPULATION etc with that ofTELEPHONY: like PLACING/ANSWERING CALLS, PROVIDING PRE-RECORDED VOICE INFORMATION, DIGIT DETECTION etc

ARCHITECTURE ALLOWS THE SCALABILITY OF CAPACITY FROM 8 Ch TO

60 Ch ALLOWS ANY INDEPENDENT APPLICATIONS CREATED

ON PC/WORKSTATION/SERVER, WITHOUT ANY CHANGE ON HARDWARE SIDE

ALLOWS FOR UPGRADATION TO OTHER PRODUCTS/APPLICATIONS WITH SIMILAR ARCHITECTURAL REQUIREMENTS


Advantages of CDOT-IVRS Hardware is a by-product of MAX* system, inherits the

advantages of MAX such as reliability,QA*, support,volumes & cost.

*MAX: C-DOT Main Automatic Exchange* QA : Quality Assurance



Advantages (contd.) System will be application independent, hence new software

applications can be developed on PC alone without any add-on cards.

Recording of announcement on the PC and downloading into the IVRS Hardware.

System scalable from 8 lines up to 60 lines by adding cards.

Increased reliability for critical applications with duplication of PC & resource hardware



Advantages (contd.) Supports both DTMF/Decadic detection.

High end systems (>30 lines) can use digital trunk interface (E1).

Table-top ergonomic design.

Operates in non-AC environment.



Applications (user initiated) Interactive changed number announcement Interactive telephone bill enquiry system Automatic fault booking Automatic fault clearance Interactive commercial information and special services

assistance Any other generic application



Applications (system initiated) Automatic bulk number change announcement Automatic payment reminder Any other generic application
