  • Recent security issues have reinforced the need for collaboration of our Defense Forces on a secure tri-services network
  • Geographical diversities and & climatic extremes in various locations across India


  • HCL Infosystems has enabled the design, development and deployment of Defence Communication Network (DCN)
  • The network has been entirely designed and developed in India
  • HCL Infosystems has designed & deployed Transportable Satellite Terminal for this project
  • DCN is a strategic, highly secure and scalable system
  • DCN acts as the converged network providing voice, data and video services to users at the Corps and Command Headquarters and strategic installations of the three Forces
  • Makes voice data and video data accessible to the three services over a secured network
  • Capable of working on both terrestrial as well as satellite modes of communication
  • The Network covers many diverse and difficult terrains across the country
  • Deploys a state-of-the-art IP/MPLS architecture that enables secure end-to-end exchange of triple play services to the users


  • On 30 June 2016, DCN – the first tri-Service communication and IT network of the Armed Forces – was deployed
  • The network has pan India reach across difficult terrains though the breadth of the country
  • DCN will transcend inter service boundaries and provide reliable communications to the strategic elements of the three services pan-India
  • The DCN will considerably improve the flow of inter service and intra service information for all the three forces
  • Enhanced communications will in turn improving situational awareness, enabling better informed decisions
