In a dynamic, high-growth, highly competitive service environment, a service provider's ability to meet increasing demands for efficiency of network resource allocation, productivity and reliability when provisioning services for customers depends on having up-to-date network inventory information available. An accurate resource inventory management system allows a service provider to improve the control and understanding of its communications infrastructure, expedite the management of customer orders and automate the provisioning of services. The basic goal and final result of presented work is the information system developed for the purposes of network inventory management and accounting tasks which is capable to meet the requirements of “Lietuvos Telekomas”. Presented work covers: · analysis and specification of requirements of “Lietuvos Telekomas” for information system being developed; · analysis and evaluation of some generic conceptual cooperative work models for the purpose to make right decision on data model of IS; · analysis of basic telecommunication services, definition of data structures for the services that are to be modelled; · analysis and specification of those business processes of “Lietuvos Telekomas” that directly involve use of network resources; · analysis of generic functional architecture of transport networks, described in ITU-T recommendation G.805; · introduce of simplified (Black box) transport network model based on physical view to the...

The Project “Resources evaluation system of SDH telecommunication network” is used for investigation of the efficiency of utilization of the existing TEO LT, AB SDH Trunk Network resources. The essential problem is the lack of precise information on the free and used resources of the Network, their distribution and usage in the optimum and efficient manner. It was rather hard to establish the free and used SDH network resources and evaluate the efficiency of the Network. This brings essential influence and difficulties into the planning of network and investments since it is rather hard to take the economically viable decisions regarding the usage of the existing resources. The SDH network resources evaluation system can be used for planning of trunk network resources and quick creation of flows’ transmission routes in a very efficient manner. The System gives the possibility to verify the new routes creation possibilities from any point of the network and execute the customers’ orders in a quick manner. The System is developed as software with a direct interface with the TEO LT Network Information System SQL Base, and is going to use the data, stored in the SQL Base. The Content of this project consists from: • Analytical part of investigation • Specification of requirements for designed system • Common system requirements • Data structure • Network Resources Information Module • Testing and User Guide According content above the System “Resources evaluation system of SDH...
