This object is the IPS mode this node has learned from IPS protocol messages received from other nodes on the ring. Since ring protection decisions depend on what is happening elsewhere on the ring, this tells the admin what state a remote node is signaling, which combined with the type object below, short versus long path, locates roughly where on the ring that reported condition originates. Seeing this report SignalFail while this local node's own auto-detect mode shows no issue confirms the fault causing ring-wide protection behavior is happening somewhere else on the ring, not at this node.
