   Professional Experience
   Centre for Development of Telematics (C-DoT) as
     Research Engineer (software) since 3rd Aug 1999.

   1. Project Name: C-FITL (C-DoT fibre in the loop)
    Its Passive optical based access network which will be
     replacing the copper wires in the local loop(between local    
     exchange to subscriber).We divided it into two subsystems :
     HDT:  Host digital terminal will be put in local exchange
                premises, which has all controlling powers.
     ONU: Optical Network Unit, which is placed in the field and
                 termination point of our access network

   V5.2 protocol:
     C-FiTL is connected to Local exchange via V5.2 interface,
     which has five protocol, naming link control, bearer channel
     control, pstn, protection and control protocols. Protection
     protocol which takes care of link failure on which all
     protocols run. When primary link, on which all protocols run
     fails, protection protocol automatically switch the secondary
     link on which only protection protocol runs in place of
     primary link. Protection protocol of this stack was designed
     and developed my me. I was also involved in integration of all
     the protocols of V5.2.

   LAPD :
     We are using links between cards for communication based
     on HDLC and UART, upper layers have been implemented
     using LAPD. I have got experience of implementing and
     testing of this protocol.

   LMI Protocol:
     To control whole system, GUI is the indispensable part of
     any system. we have developed LMI_PROTOCOL for
     communicating with NMS through RS232 link.

 M68302 micro controller:
  It is a micro controller from Motorola which has   
  68000 as core processor and a RISC    
  communication processor. The implementation
  and stabilization of this device driver was one of
  the major and difficult part of this system as all
  cards are having at least one M68302.

 Munich32 (Multichannel Network  
 Interface Controller for HDLC):
  The Multichannel Network Interface Controller
  for HDLC (MUNICH32) is Multichannel
  Protocol Controller, which handles up to 32
  data channels of a full duplex PCM highway.
  It performs layer 2 HDLC frmatting
  deformatting. It has 32 channels and 32
  timeslots each of 64kbps, It gives variable data
  rate depending upon the number of timeslots  
  assigned to a channel. So one can achieve
  following combinations:
    - Single channel with data rate of 2.048 Mbps(
       64kbps*32 timeslots makes 2.048 Mbps)
    - 32 channels each with 64kbps data rate.

 Fault Management:
  We have our ONUs spreading at long distances
  in the field so we need to have fault
  management which can report all the faults
  (alarms) happening in HDT(Host Digital
  Terminal) and ONUs so that it can be sorted
  out as soon as possible. I designed fault
  management for whole system which is based
  on object oriented approch.

 BootUps and Diagnostic Routines:
  Design, development and testing of boot-up    
  and self-diagnostics software for 2 types of
  boards in C-FITL system. The system
  initialization module is responsible for bringing
  boards to a stage where software applications
  can be started. Besides individual board
  -diagnostics, it also performs several data-path
  tests on whole system, during first-time
  installation. The boards use Motorola M68302
  and M68040 processors.
 
 Integration Of HDT:
  I was one of the members of intergration team
  of HDT, which was started from testing
  of communication links among various cards
  and ended after making first call.


  2. Current Project:
  Gigabit PON  (study phase)
    It is optical fibre based broadband access
    network which will provide following services

    -Virtual Private Network
    -Gigabit Ethernet
