摘要: A communication system, network node, and port architecture are provided for transporting data across a ring network. If node detects signal failure, the of configures itself as timing master communicates shutdown command to other nodes. In addition, sets an internal flag signaling this “signal off” event. All nodes, which receive flag, do not set status, instead, save status “no fault saved.” Accordingly, it can be easily determined where loss occurred.
