Design & Development of Standard Indigenous Call Centre
Equipment and Application Software with Multilingual
In the current scenario establishing a Call Centre involves
procurement of expensive Switches, Servers and Application
Software etc. at exorbitant cost. This project aims at
providing a low cost solution for the entire application
needs of a Call Centre.
The solution being developed is soft switch based, which
eliminates the need of buying costly Switches. The objective
of the project is to provide an integrated solution for Call
Centre needs like features for incoming and outgoing calls,
Web Integration with e-mail client and Server program, Chat
program, Web Callback etc. Apart from this, a small CRM
application is also integrated, which can be modified as per
the customer needs. Automatic Call Distribution features are
The development of the project is under going.
Hardware/Embedded Systems Projects
In line with its mandate to be an R&D organization, the Unit
has augmented its R&D base both in terms of availability of
qualified manpower and latest systems/tools like Sun Work
Stations, Cadence Design Software, ARM Development Tools and
RTOS Tools Software. A number of projects, sponsored and
in-house, were taken up during the year. The major projects
under taken and products developed are:-
Thin Client (Neuron)
Neuron has been designed to be a complete solution for
network clients. Each Neuron has its own embedded memory,
processor, Ethernet, graphics, sound and most other
capabilities that a modern PC has. At its heart is a
versatile STPC-Atlas x 86 based processor integrated with
modern capabilities like 2D graphics acceleration,
multimedia processing capabilities, SDRAM controller and
several other features. The main board has a sound card; an
Ethernet Card and SD RAM. The storage memory Device is a
Disk on Chil (DOC). This DOC works exactly like a normal
Hard Disk. It is loaded with one or more OS and a
combination of utilities. This architecture gives Neuron
fast and powerful processing capabilities. A small external
mains adapter supplies the power to neuron, thus preventing
the server from getting overburdened. The Neuron runs on a
Linux platform but can work with most windows programs as
well, thus, the software costs for Neuron is very less and
software are required only at the server.
A Thin Client terminal only processes keyboard and mouse
input and screen output, leaving all application processing
and storage to the server.
Unlike a traditional PC with high-speed processors and data
storage, these terminals are optimized to act solely as
windows to the server where userís applications and data
reside. Instead of applications running on individual PCs,
all applications are run from a single server, greatly
simplifying the administration and support needed to run a
network. The note worthy features of the Neuron are :-
Very economical setup of networks
Only server up-gradation required to upgrade the network
Stable, robust and secure networks
Compatible with windows as well as UNIX platforms
Integrated on board Ethernet, display, sound and serial
2D graphics acceleration
Provision for USB, hard disk CD, floppy drives and modem
No threat of viruses
No danger of data loss due to improper shutdown
The transfer of technology of the product is being explored.
External (serial) and Internal (PCI) Modem
The unit has developed a modem based on a single chipset
from Conexant Inc. USA. The design is aimed at highest
functionality at lowest cost, to meet the current 56Kbps
standards. The technology has been transferred to BPL &
Home Inventory Management System
The project, which was taken up in-house was aimed at
designing and developing a system for monitoring of home
inventories like soaps, toothpaste and other household items
of day-to-day use. The system is capable of connecting to
the racks in which each drawer is marked item wise. The
system will keep track of all the drawers and once a
particular item goes below a predefined limit, the system
will send email to the vendor and the order is placed
The project has been successfully completed.
Solar Power Grain Moisture Measurement System
The moisture content plays a vital role in determining the
period of grain storage in the go-downs. Higher moisture
content attract various fungi and bacteria thereby causing
damage to the grain whereas very low moisture content affect
the nutrient content of the grain.
Solar Power Grain Moisture Measurement Unit (SPGMMU)
measures the moisture content of grain/seeds. In addition,
the system will be utilized to know the optimum stage of
harvesting, storage for extended period and for research
work in the laboratory. The system has wide applications in
pre-dominantly agricultural communities/regions.
Photovoltaic Main Electronic Interface Unit
The conventional sources of energy are depleting rather
fast. Keeping in view technology development on PV utility
taking place elsewhere and as an import substitution effort,
a project was undertaken to design, develop and fabricate a
2 KVA PV utility interface. The system consisting of the
following 6 modules has been successfully developed:-
DC to DC Converter
DC to AC converter
SMPS Power Supply for Control Card, drive Circuits and
Power flow and Synchronization Control
Supervisory Control and Metering and Load Management
CP Control Card
This system is ideal for rural areas where the electricity
supply from the grid is infrequent. The surplus power
generated can also be fed into the grid.
Solar Powered Uninterruptible Switch Mode Power Supply for
Solar powered uninterruptible switch mode power supply is
used to generate various voltage levels (regulated) required
to run a PC. The system consists of an uninterrupted power
supply, an AC toDC converter and a DC to AC
converter. The system takes solar energy as primary source
of power. It switches to AC line, when solar power is not
available and switches to Battery bank when both solar and
AC Power are not available. Software monitoring facility is
also provided to monitor the power status of the system.
This technology/product has immense for use in the
rural/remote areas where the electricity supply is scarce or
Development of Technology for Tele TV Conferencing using
Conventional Telephone Lines
The project aims at developing technology for transmission
of audio and video through conventional telephone lines. The
main features include, the compression of audio and video
data and data transmission over line. The compression used
for the video is as per H.263 standard, for audio is as per
G.723.1. The video for transmission is PAL based, the video
would be transmitted QCIF resolution. The audio would be
compressed to as low as 5.3 kbps as against the standard 64
The project is in development stage.
Solar Home Lantern
This system is designed to work as a night lamp in homes,
particularly in the remote areas.
