Abstract, Apparatus and method for identifying the location of a lost token signal continuously transmitted on transmission paths interconnecting nodes of a network to sequentially enable the nodes to write data onto the network. The arrival of the token signal at each node is recorded in counter states of a token track counter corresponding with the node. The recorded binary counter states are compared upon the failure of the token signal to arrive at a node to detect mismatches and transitions occurring between adjacent nodes counter states identifying the network location of the lost token signal.
