  Centre for Development of Telematics (C-DOT)

  Aug 2003 - Jun 2017

  Projects : G-PON Software, CWDM, EMS,Summary : Setting and leading the development of world class softwares that meet strategic needs of modern telecommunication, conforms to international standards ( 3GP, ITU-T and Broadband forum) and complies to stringent regulatory requirements. Well versed with complete SDLC. Timely promoted throughout career in R&D organization.- Developed application software for GPON project that has won tenders to provide technology backbone for $5.6 billion BharatNet project under Digital India initiative. The initiative will connect 250,000 Gram Panchayats providing them with video, voice, and data services bridging the rural-urban digital divide. G-PON project was adjudged the winner of the IESA Technovation 2015 award in most innovative product category.- Lead development of pizza-box variant of GPON OLT to cater urban markets. Product was awarded for innovation by ELCINA in 2013-14 for its ultra-compact design.- Comprehensively redesigned the most critical datapath module in GPON systems improving functionality, efficiency, maintainability. The design made system inter-operable resulting in development of four more variants of GPON with components sourced from different vendors.- Designed and developed single box ONT devices that deliver all four services ie. Voice, Video, Data, and CES- Enhanced capabilities of G-PON OLT stack by implementing L3 routing protocols which lead to a cost-effective single card solution and saved millions of CapEx of network service providers - Designed in-memory database that improved system availability to 99.999%.- Developed a new debugging tool to fine-grained localize datapath issues in G-PON devices that resulted in a 20% improvement in software delivery time- Developed applications to facilitate online debugging of system installed in remote areas saving personnel man-hours and travel costs. Show less Projects : NMS, W-CDMAAchievements: - Developed software modules for Course Wave Division Multiplexing ( C-WDM ) project which is commercially deployed in country's largest BSNL network between Delhi and Jaipur.- Developed core components of L-NMS project : (a) Subscribers Management of Siemen's EWSD and OCB exchanges using Perl and Bridge scripts; (b) Installation software using TCL/TK, shell scripts, and Oracle database on Solaris~8. L-NMS project is successfully rolled out at more than 40 sites of BSNL network and managing 0.25M Network Elements deployed in India- Developed OAM&P stack of RNC in W-CDMA project from requirements gathering till coding using Socket programming and X/Motif language.
