Abstract:
In this report several key issues like maintenance, management and understanding of a complete Network system of Radiant Communications Limited [RCL] has been focused. The network system of RCL provides different kinds of services such as ‘Data connectivity’ service, ‘Internet’ service, ‘Security’ service, ‘Fiber optics network’ service, ‘Network infrastructure design and maintenance’ service, and Support. For proper network design two or three back up links were preserved in order to provide secure service during power instability problem. As a technical support I had to face most of the problems for data connectivity, internet service and fiber optics network. Authentication failure of a user was one the problem. By using ‘’WINBOX’’ software it was possible to see the details about that client and to solve that problem. Another technical problem was Fiber cut/break problem which happened several times. One of the plausible way to know about fiber cut is to first check the DB of that link. If there is no DB, then to use optical time-domain reflectometer (OTDR) machine. The OTDR machine inform us the total distance, from where the fiber is cut and the DB also. Besides there were many other technical problems. This internship has given me the opportunity to work and learn some software and hardware architecture practically and acquire a clear knowledge about understanding network system based problems and to find some credible solutions.
