## Abstract

Disclosed is a network appliance, and a system comprising same, for detection of a physical condition of a network cable. The appliance includes one or more line monitoring circuits each of which is adapted to monitor a power barring line or a ground line of the network cable, by measuring one or more electrical parameters of the monitored line. An alert condition detector is adapted to receive from the monitoring circuits, information indicative of measured electrical parameters of the monitored line and to use the received information to identify an alert condition indicative of a physical condition of the network cable.
