A Network Management Solution for Pre- Alarm Detection in EPU Telecommunications Network

Abstract

The pre-alarm detection is a novel method for ensuring high availability of operational traffic in corporate telephone network of Electric Power Utility, beside usage of redundant elements and alternate routing. In this paper, is examined software solution for pre-alarm detection in network management domain. After the analysis of the domain characteristics was proposed solution based on analysis of traffic on direct links between telephone exchanges. In order to find when high priority Integrated Service Digital Network (ISDN) or Internet Protocol (IP) links are faulty, calls over high voltage power lines are analysed in two step process, using data retrieved from Call Detail Records of telephone exchanges. Increased accuracy of detection characterizes this solution compared with the previously proposed, because there are no false negatives in the detection process. In this research was verified that proposed solution can be implemented as an additional layer in network management hierarchy without change of existing network management system software or infrastructure.
