Abstract
A method and apparatus are provided for determining and indicating the integrity of a network that interconnects a group of nodes. Each node includes an internal clock (42 or 58), an indicator (27) for emitting a signal at a synchronized signaling interval and a processing unit (36 or 60) electronically coupled to the indicator and the internal clock. The processing of the node causes the indicator to emit a signal at the synchronized signaling interval. When the integrity of the network is intact, the processing unit of each node causes the indicator of the node to emit a signal at the same synchronized signaling interval. As a result, all of the indicators are emitting signals in unison. When the integrity of the network has been lost due to a malfunctioning node or physical break, on a group-to-group basis, the indicators of those nodes improperly communicating with each other emit signals at different synchronized signaling intervals. As a result, the indicators emit signals in an asynchronous manner.
