This project is designed to form bridge between rural exchanges and district telecom and to statewide telecom. By implementing this idea in a telephone exchange will improve the quality of work.
We have considered many factors in this project starting from coaxial cable to optical fiber cable along with security and safe operation of the exchange, without any human interference.
By implementing our idea, the user can identify the cable failure (conductor), OFC (Optical Fiber Cable) failure, fire hazardous, human interruption, RDX bomb detection, air conditioner failure, generator and UPS monitoring. All the above plays a vital role in almost all the exchanges irrespective of the size.
We would like to provide embedded solution for the above. A perfectly crafted 16F877A controller will be used to make further perfection of processing.
All the above mentioned events will be demonstrated lively. This is not a simulation; this could be the real application model.
Status of the one exchange will be connected to the main exchange using SCADA software. This software allows to propagating the exchange related parameters to web. If incase of any communication failure, can be identified automatically.
Both the transmitting person and receivers can identify the transmission failure.
Parameters and Events taken into consideration
1. OFC failure
2. Coaxial cable failure
3. RDX bomb detection
4. Intruder sensing
5. UPS voltage monitoring
6. Major rectifier bank monitoring
7. Floor temperature monitoring
8. Changed number announcement
9. No tapping
10. Auto fire put off
11. Stand by air conditioner ON
12. Flame detection
13. Multimedia for all
14. Staff attendance
All the above events can be made into graphical form can be recorded without disturbing the acquiring. This could be a single chip solution for SCADA telephone exchange.
This project consists of self-sufficient sensors and transducers supported with embedded controllers.

SCADA systems are widely used in industry forSupervisory Control and Data Acquisition of industrialprocesses. Companies that are members ofstandardisation committees (e.g. OPC, OLE for ProcessControl) and are thus setting the trends in matters of ITtechnologies generally develop these systems. As amatter of fact, they are now also penetrating theexperimental physics laboratories for the controls ofancillary systems such as cooling, ventilation, powerdistribution, etc. More recently they were also appliedfor the controls of smaller size particle detectors suchas the L3 muon detector and the NA48 experiment, toname just two examples at CERN.SCADA systems have made substantial progressover the recent years in terms of functionality,scalability, performance and openness such that theyare an alternative to in house development even forvery demanding and complex control systems as thoseof physics experiments. This paper describes SCADAsystems in terms of their architecture, their interface tothe process hardware, the functionality and applicationdevelopment facilities they provide. Some attention ispaid to the industrial standards to which they abide,their planned evolution as well as the potential benefitsof their use.
SCADA stands for Supervisory Control And DataAcquisition. As the name indicates, it is not a fullcontrol system, but rather focuses on the supervisorylevel. As such, it is a purely software package that ispositioned on top of hardware to which it is interfaced,in general via Programmable Logic Controllers (PLCs),or other commercial hardware modules.SCADA systems are used not only in most industrialprocesses: e.g. steel making, power generation(conventional and nuclear) and distribution, chemistry,but also in some experimental facilities such as nuclearfusion. The size of such plants range from a few 1000to several 10 thousands input/output (I/O) channels.However, SCADA systems evolve rapidly and are nowpenetrating the market of plants with a number of I/Ochannels of several 100 K: we know of two cases ofnear to 1 M I/O channels currently under development.SCADA systems used to run on DOS, VMS andUNIX; in recent years all SCADA vendors have movedto NT. One product was found that also runs underLinux.
This section describes the common features of theSCADA products that have been evaluated at CERN inview of their possible application to the control systemsof the LHC detectors [1], [2].2.1 Hardware ArchitectureOne distinguishes two basic layers in a SCADAsystem: the "client layer" which caters for the manmachine interaction and the "data server layer" whichhandles most of the process data control activities. Thedata servers communicate with devices in the fieldthrough process controllers. Process controllers, e.g.PLCs, are connected to the data servers either directlyor via networks or fieldbuses that are proprietary (e.g.Siemens H1), or non-proprietary (e.g. Profibus). Dataservers are connected to each other and to clientstations via an Ethernet LAN. The data servers andclient stations are NT platforms but for many productsthe client stations may also be W95 machines. Fig.1.shows typical hardware architecture.
