摘要：In this paper we consider the mixed telephone network of electric power utility consisting of IP, ISDN and Power Line Carrier links. Very important demand in the network is high availability. The central detector of IP and ISDN link failure (pre-alarm) is presented. The detector function is based on the prolonged response time of the network in the case of IP and ISDN link failure. We define undesirable events in the detector operation: false pre-alarm and miss detection, and we derive the expressions for their probability calculation. It is indicated that centralization of this detector is merit, which facilitates testing of the whole network from one location. [Projekat Ministarstva nauke Republike Srbije, br. TR32007]
