The said project includes migrating to VoIP based Train Control Communication Systems and Video Surveillance System (VSS). Scope of work includes Design, Planning,
Supply, installation, fixing, configuration, integration and commissioning of this communication system. The project is targeted for completion within12 months.
This state-of-the-art IP infrastructure can meet all the current and future connectivity requirements of the Railways such as Passenger Reservation System (PRS), Freight Operations Information System (FOIS), Coaching Operations Information System (COIS), Caution Order Management System, RailNetfor supervisory offices etc. sand all future applications aimed at enhancing safety and efficiency of Train operations.
