It was not a bludge job.
It was a difficult situation for me, for I was as good as my last project.
So I had to work hard to keep my job, did one project after another.
Well, I take this opportunity to give a small brief of the works I did for TRL and BEL, from 1978 to 2006. From my extended resume.
Just for the heck of it!Going down memory lane.
********
Detailed Work Experience of Arindam Banerjee (with timeline, from 1978 to 2006)
Briefly - Over 27 years experience in cutting-edge R&D and Business-related projects in a variety of disciplines. I have the urge to do new things, and then move on to other projects, the more difficult the better. Success in many different technical areas (mathematical modelling and computer simulation with GUI, development of software tools, analysis of large and complex Call Centre Networks and Business Activity Situations,, data analysis from legacy systems, teletraffic engineering, CCS7 data handling, database techniques related to electronic directory systems, communications security, radar data processing, antenna and passive microwave equipment design, development and testing) and ability to interact with various kinds of people make me confident in dealing with any management or technical situation creatively in a mature, efficient and productive manner.
- Jan 05 to Feb 06: Used TRL-developed Microsoft Excel tool “Coral Sea” to successfully give recommendations to the Fairfax Call Centre. Pinpointed the area that required improvements, after studying their call centre Management Information System data and putting them in Coral Sea. Similarly, obtained data from Transonic and showed the importance of multi-skilling in quantitative terms, this time using an old version of the CCT simulator. Thus, showed the practical use of this new software based not simply upon the Erlang formulas but upon the fundamentals of queueing theory, with mathematical extensions to it.
Developed Borland C++ Builder6 based software tools to analyse and present in graphical form the information from the legacy data systems for both the Victorian and South Australian Radio Networks. These are known as Darshan 1.0 and Darshan 2.0 respectively. Used Darshan 1.0 to analyse Victorian Govt.’s Radio Network data, and pinpointed the so far unknown traffic profiles graphically on a time basis, and showed the frequency of usage of the network per customer number. The times of lack of usage were shown clearly, and indicated enhanced business opportunity relating to non-emergency calls. The South Australian Radio Network “Coronial” Data was analysed, concentrating upon the time when fires broke in the peninsula on 11 January. A comprehensive analysis was done using Darshan 2.0, and a lot of information, about call arrivals on second-by-second basis, customer usage patterns, busies statistics, site utilisation, etc. was generated in graphical form. They clearly showed that Telstra’s network had throughout been operational. Created a fast and powerful computer simulator of the South Australian Managed Radio Network, to show how the channel capacities can be improved for best possible Quality of Service, and also for improving business opportunities, by taking the best among competing decisions involving customer management and parametric changes. Programming in Borland C++ Builder6 from scratch, for this.
Impact: Telstra got better business favour from Fairfax and Transonic for pointing out aspects in their workstyle that would not have been normally noticed. Mark O’Reilly, National Manager Operational Performance, asked specifically for Arindam to do the simulation for the Radio Networks, as he had prior positive experience with Arindam in the earlier CCT project. Telstra’s role in maintaining the operation of the South Australian Govt. Radio Network has been upheld, and that may be of importance in litigation related to the coronial inquiry. It is expected that this will lead to better tariffing structures. Better ways of handling the Australian Radio Networks, as opposed to simply running them, are expected to happen with continuing emphasis on system simulation. More profit can be made, when the data is properly analysed with respect to traffic patterns over time, when businesses are allowed to use the Radio Networks – so long as the Quality of Service levels get continuously monitored and proper remedial situations taken with onset of genuine emergencies. The Managed Radio Simulator is expected to be used for training, dimensioning and network management.
- July 02 to Dec 04: Involved in the optimisation process of Telstra’s Business Call Centres, relating to Telstra’s top Business and Government clients, in the CCT (Customer Care Transformation) Project. This dealt with the handling of emails, documents, and telephone calls; and the performance improvement of staff through appropriate work routing, through appropriate modelling of their business processes. Constructed a simulator for modelling the work function, which included making a special simulation for the Genesys CTI system. This work was done as part of a team activity including personnel from within and without TRL, numbering up to 7. Was personally responsible for the intricate coding of the software simulation for the mult-skilling aspects. For training of Call Centre Personnel, wrote an Excel worksheet known as “Coral Sea”. This related to the modelling of a generalised call centre; some calculator type work sheets; a tool for rostering staffing based upon non-Erlang calculations but upon newer and more solid Queuing Theory, giving much better predictive value; and finally, a worksheet for the analytical simulation of a Call Centre network based upon the earlier-described model, that took teletraffic, costing, quality, customer inputs and gave outputs graphically, showing the tradeoffs clearly. APIA came back to Telstra, threatening legal action. They had made changes to their system after their initial success, and were now getting bad results. Their data was once again analysed and changes recommended. PACT was slightly modified to do this work. Throughout this period (and later) worked with several of Telstra’s Business and Government staff, and attended many meetings with them.
Impact: Many keen insights of the existing work patterns became obvious as a results of this simulation, and the recommendations arising out of this work were used performances. The role of simulation itself, for extracting better performances, and pinpointing areas of surplus and areas of stress, became very clear to top management. APIA was satisfied with the work and did not press legal matters.
- Mar 01 to June 02: Worked on the software development of H.323 Gateway in Visual C++. Modified the signalling software obtained from RadVision Company to allow automated Microsoft Netmeeting calls. Gave a successful demonstration of same. Worked on the analytical simulation of the Genesys CTI (Computer Telephony Integration) system. Developed new analytical approaches based upon Arindam’s extension of “Little’s Result” and created an Excel tool that balanced quality considerations with respect to costs in terms of equipment and staffing and handling times. This was called the “Load Balancing” tool, and showed how useful Genesys implementation of CTI could be to balance loads among work groups. Worked on the theoretical basis for determining the construction of SLAs (Service Level Agreements). Attended Java courses and learnt Java language. Created personal website. Attended BEA Weblogic courses on Adminstration of BEA Weblogic Server; Developing Enterprise Applications using EJB and JMS; Developing Enterprise Applications with BEA Weblogic Server and the J2EE Core Technologies. Participated in a team effort to create web contact centre IVR-type applications using Weblogic. Used PACT to recommend the Nortel Spectrum system to APIA (Australian Pensioners Insurance Agency) to optimise performance of their many scattered Call Centres all over Australia. PACT modelling was instrumental in Telstra getting a $3 million annual contract, and it also led to improving the performance in the APIA Call Centres
Impact: The load balancing tool was very popular and gave a boost to the utilisation of Genesys within Telstra as its load-balancing capability was clearly demonstrated. Use of SLAs to fix quality standards became an accepted practice.
- Jan 99 to Mar 01: Improved the performance of Telstra’s 132200 Call Centres through PACT type simulation (more about PACT later). The problem related to finding the best way of splitting the workforce into those serving the favoured customers well without compromising on quality of service to the remaining customers. The Spectrum system was modelled with an extension of the PACT approach, and recommendations were made from the results of such simulation. As part of this exercise, a nagging problem was solved relating to high waiting times at certain hours. PACT found this out without being “told”, and the problem was also solved with simulation. PACT simulation showed clearly when this huge waiting time would happen, and how it could be avoided if the staffing was scheduled for arrival some time before the demand. Worked with Telstra staff based in Sydney for this project.
Impact: Decreasing the waiting times in peak periods for the 132200 Call Centres could not have happened without the PACT approach, as the standard segmented scheduling approaches for allocating staffing did not have the “flow-on” effect that PACT naturally has. This persistent problem that had eluded experts was thus solved.
Worked on CTI-related projects, and was involved with the Business Modelling Group in this period. Assisted in the development of BIZSIM, a business gaming software.
- Jan 98 – Dec 98: Developed a user-friendly graphical user interface (Borland C++ Builder) for the Centrelink simulator, which takes in thousands of parameter values, and outputs user-configurable graphs on all aspects of interest in Call Centre teletraffic activity. This is now a tool used by Centrelink, called PACT (Performance Analyser of Call Centre Teletraffic), which has caused savings to Telstra by reducing operator wait times, thereby freeing more lines as well as improving Quality of Service drastically. PACT became a showpiece project demonstrated to visitors coming to the TRL foyer.
Impact: Using the Borland C++ Builder was a new initiative. Coding with GUI ability was found very useful for quick and accurate development of complex software involving visual representations of huge amounts of both input and generated output data. Unfortunately, Arindam became the only one working with Borland PowerBuilder and the TRL community ignored this immensely rich but demanding software development environment.
- Feb 97 to Dec 98: Worked on simulating the performance of DSS (now Centrelink) teletraffic call centres, in the area of modelling and optimising parameters for the efficient performance of the National Automatic Call Distribution (NACD) function provided by the Nortel switches, which essentially integrates all the sites with few groups each, by providing uniform quality of service to customers all over Australia. As part of Telstra’s contract with DSS, developed (singly) a discrete-event simulator to cover the performance of the call centres using the NACD algorithm.
This work has been described as “breakthrough” by Centrelink, as it gives results currently impossible with analytical methods, such being the complexity of the problem. The code was specially written for DSS, from scratch, in Borland C++, without going in for expensive general purpose simulation packages which probably could not handle the task with any efficiency.
The simulator can handle any number of sites, any number of groups with any number of staff, any calling and service profiles. It gives details every instant of everything happening in the system. It handles the complex NACD algorithm, a critical feature being dual queuing of a call in two “best” sites. While written for a specific purpose, this tool can be used for many teletraffic situations.
Interacted with Nortel staff and two top teletraffic experts (Prof Les Berry and Prof Richard Harris of RMIT) who validated the software. Travelled several times to Canberra, to meet Centrelink personnel and Telstra’s staff operating the Call Centre Network, for data inputs, presentations, and demonstrations.
Impact: Telstra’s annual $60 million contract with Centrelink materialised, ousting the competition from Optus,, thanks in part to the above work that Telstra had to supply as a contractual obligation. As a result of the insights obtained from this tool, later named PACT, Australians contacting Centrelink had their wating times reduced drastically. The calls were more efficiently routed. Without long waiting times, the network efficiency increased as so many lines were not getting held. Many what-if scenarios could be tested without changing the network status, for optimising parameter values. This complex software simulation effort thus was a new and highly successful approach.
Supervised another project with students of RMIT along with RMIT staff - Network Defect Simulator. This project aimed to make automatic surveys of customers, seeking to know their opinions of call quality. Information processing would also be automated.
- June 96 to Feb 97: Co-ordinated a team of professionals from different skill areas (Human Factors, Speech Processing, Listening Tests, Software Engineering) to find outstanding defects as subjectively perceived in Telstra’s Public Switched Telephony Network. Based upon published reports, constructed a tool to predict customer response to various levels of defects such as noise, echo and amplitude levels. Helped in forming a report which related subjective responses of customers with technical specifications
Supervised a team of two RMIT students working on a 18-month project with TRL - “Software Speech Controller”. This related to injection of specified levels of commonly found network defects to “clean” speech, in order to get samples for listening tests, with software in a very user-friendly Windows 95/NT environment. This project was successfully completed, and received much praise.
- Feb 96 to June 96: Worked on methods to improve Telstra’s ability to increase repair times for telephone faults. Developed a tool, after studying the database records of all faults. This tool (in Excel) used teletraffic analysis to predict the level of improvements possible given quantified efficiency increases.
Impact: Very high. This tool was used by Telstra for scheduling resources more efficiently. Repair times were reduced drastically, once the logging data was correctly analysed and processed with the appropriate teletraffic formulas.
- Feb. 94 to Feb. 96: Worked on the analysis of CCS7 data obtained from the Telecom network. Attended intensive Telstra conducted courses on CCS7 and interacted with professionals and technicians in this field. Various CCS7 services were studied, chiefly with the direction towards link dimensioning and congestion control. A number of C-Unix programs using original algorithms were written to investigate burstiness on any arbitrary time scale, and both simulation and M/G/1 analysis were done to investigate transmit buffer queuing delays. Made contributions to international standardisation: "Studies in Signalling Traffic Variability" ITU-TS SG2 WP3 Delayed Contribution D.136, Nov. 1994, Australia. As a result of this research, dimensioning recommendations for CCS7 traffic were implemented in the Telstra CCS7 network. Specifically, the impact of long messages in the network was predicted realistically. Further, work was done (Perlscripts were written) to manage operational measurements efficiently for the technicians. Made a link dimensioning tool in Excel.
Impact: Very considerable. Telstra could as a result fo this work use new CCS7 services with long messages in the existing signalling network knowing that existing services would not be disrupted unduly, provided the proper dimensioning strategies also given were implemented. The Perlscript was very useful to the technicians, and saved time. Telstra’s image was enhanced with the ITU contribution. The new analytical methods developed were used successfully in other projects as well.
- Dec. 93 to Feb 94: Initiated study of distributed database systems, with a view to rationalising Telecom Australia's Calls Database. Gained expertise in object-oriented programming, chiefly C++.
- Aug. 93 to Nov. 93: Implemented in C language certain standards (ISO/IEC JTC 1/SC 27/WG 2N) relating to hashing functions for secure communications, using multi-precision arithmetic routines.
Impact: This was one basis for making future recommendations to Telstra Business Groups.
- July 92 to July 93: Brought out a report entitled "Security and other Pay-TV Issues". This report deals with the security aspects relating to the dynamic Pay-TV technology. The basic principles are described, the issues relating to key management are stressed, as also newer technologies involving smart cards and authentication systems.
Further, brought out a report entitled "Narrowcast Security Options". This dealt with the security aspects of narrowcasting, and also how the principles relating to Pay-TV could be adapted to have secure terminal-to-terminal communication. The most recent directions and developments of relevant technologies and businesses were indicated.
Impact: Very considerable. This was very highly appreciated by Telstra business clients who made this report a cornerstone in decision-making, chiefly for the rollout of Pay Television. Many technical issues were clarified.
- Feb. 92 to June 92: Developed multi-precision arithmetic routines (in the C language) and used them to implement crytographic algorithms relating to encryption and decryption.
Impact: A first-time usage of the multi-precision arithmetic routines in TRL showed the potential of genuine security capacity to colleagues and clients. It was used for checking the authentication protocols for commercial transactions, and that led to TRL taking an initiative in international standardisation of computer security.
- Aug. 90 to Jan. 92: Brought out a research laboratory report entitled "Impact of New Services on Directories." The report elaborated the centrality of the role of electronic directories in providing value added services, taking into account contemporary technological developments. The question of the structure for the Personal Telecommunications Identifier in Universal Personal Telecommunications was dealt with. The new concept of "Complex Searching" was introduced, whereby it would be possible to locate people or services using any set of attributes out of a theoretically unbounded set of attributes. The implementation strategies involving Intelligent Networking were discussed, and they led to a generalised directory architecture, owing to the new concept of "global attribute capture", where attributes are globally indexed with certain locations holding monopoly over certain defined attributes. Some services naturally following from "Complex Searching" were discussed.
The above study also included an overview of the latest approaches relating to physical database design.
Impact: This was regarded as a highly important report, as it set new thinking and new directions in many areas, chiefly in the anticipation of the potential of Search Engines in Internet, as it followed from Arindam’s 1987 paper “A New Method for Partial-Match Retrievals”. However, the business and technical scope of this paper has not been fully realised yet.
- Oct. 89 to July 90: Worked on the software implementation of CCITT X.500 standards, that is, the Corporate Electronic Directory System. The language used was C, on Unix, using Apollo Domain systems. Greatly improved the search filter algorithm for query processing, which led to higher marketability of the product. This work (my first in Australia) was done without any technical guidance.
Impact: This product was later used by IBM globally. In Telstra this software is used on a daily basis as PeopleSearch in Telstra’s Intranet.
- Aug. 87 to Sep. 89: Worked as a Deputy Manager in the Radar Data Processing Department of Bharat Electronics Ltd., Ghaziabad, India. Managed a team of engineers and technicians (numbers ranged from 4 to 10) in a project dealing with multi-sensor (mainly radar) tracking for Indian Navy's new frigates. Developed a comprehensive simulation program (in Pascal/VMS, on VAX 11/785) to get raw radar video, considering all 3-D radar characteristics including user specified antenna radiation patterns, ship movements, and moving targets with dynamically varying cross-sections. Various video extraction schemes (from background clutter) were also simulated. Developed an Ethernet simulator to study system load characteristics. Worked on the development of multi-sensor tracking algorithms for the Indian Army's ground-based radar systems, to provide an integrated picture to Command and Control Systems.
Gave numerous presentations, and had many meetings with clients (Indian Navy officers), and also wrote many internal papers.
As a personal project, completed a Radar Maintenance and Toubleshooting Program, which was to be installed on PCs supplied with every radar system.
In July 1989, was selected after a tough national competition to a fully paid 18 month top management training course at a national facility, Management Development Institute, Gurgaon, Haryana State. Did not avail of this training because of emigration to Australia.
- Jan. 87 to July 87: Worked as systems manager for the newly imported VAX 11/785 computer system.
- June 78 to Dec. 86: Worked first as a Deputy Engineer, and later as a Senior Engineer, in the Antenna Development Department of the Bharat Electronics Ltd. Successfully completed many projects in this period, often singly, or as a leader of a small project group of 3-4 engineers. Notable achievements are:
* Developed a new technique for realization of large stripline circuits. Such circuits were very effectively and economically used in feeder circuits for IFF array antennas, and as integrated feeding cum radiating elements for shaped elevation beam IFF antennas.
* Developed, tested and productionised a range of monopulse stripline IFF array antennas.
* Brought forward a new design approach for an atmospheric (MST) radar antenna.
* Was involved in the design and specifications for Indian Air Force's Early Warning Radar System Antenna.
* Was responsible for the electronic design,. development and testing of the Primary and Secondary (Integrated) Radar Systems for the indigenously developed (and now productionised) Low Level Aircraft Detection System. The Secondary (IFF) antenna, in particular, had novel features and gave world's best specifications.
* Developed, tested and productionised an omnidirectinal high-gain antenna for Distance Measurement Equipment (DME), used in airports for navigation.
* Modified Russian developed P-15 radar equipment (for both mast mounted and vehicle mounted versions) to make its IFF performance suitable for Indian military conditions. This was a very difficult task as the Russian radar systems had a much lower frequency for IFF operation. However this task was successfully done, and verified in flight trials where I interacted with military officers and men. Devised a new radiating element design for the mast mounted version.
In all the above work, did computer simulation of antenna performance in Basic and Fortran using IMSL libraries. Documentation was extensively and thoroughly done for the purpose of prototyping and later productionising. Various test equipment (network analyzers, antenna test equipment, etc.) were mastered. A great deal of co-ordination was involved with the antenna testing group, the testing and production groups, the quality assurance group and of course the users.

> Why the do you whine about this?
Because racist bigots like you were always there to deny me any advantage for my genius and original works, which changed not just Australia and the world, that are far beyond your understanding.
They still do that, just because they are racists and bigoted like you.
Quite a habit for them.
> Most I know have had to find other jobs after being made redundant.
So did I, with great good luck, as they all knew about how I had made physicists look like dumbfucks by debunking e=mcc with a far superior alternative formula, and that they did not like, from a brown Hindu not despising his religion to keep chaps like petzl happy.
Stil, they needed my genius. In Telstra they wanted a system to pass messages very fast between unlimited number of robots.
I studied and passed DBA certification and was employed by a private company. They had to hire me, could not find anyone else for that job. They hated me all right for my new physics ideas, as all of you here, but what could they do?
Again, I was exploited there as I had been, but so what,
I left that for a $550 a day DBA job, and worked there till I retired from active employement (32 years).

A lie, again. Telstra did not give referrals to redundant employees. That is company policy.
> Right now I get free calls Australia wide $10 a month compared to $200

In India I get mobile internet 1.5Gb a day, unliimited calls, for $5.00 PER MONTH.
Fool, in Telstra we made the whole network, for the capitalist parasites to feed on.
The result is that without genius or talent, just copy and paste what the Americans give, your sort has far too much company. The whole nation is getting to be like you, more and more stupid and unethical.
To repeat, that is why we need the VOICE, to keep the public sane, kindly, wise and moral.

Lying, as usual, this racist and bigoted creep.
