摘要 |
A method for protection of STM-n/OC-n clear channel connections calls for a protection diagram allowing protection of STM-n/OC-n clear channel signals transmitted from a source point to a destination point. This protection allows overcoming a fall along the path between source point and destination point. It can be used in different types of network structure, for example "ring" or "mesh". The method calls for duplication of STM-n/OC-n signals at the transmitting end of the subnetwork and transmission over two different routes which can be defined work subnetwork and protection subnetwork. To ensure success of the protection diagram the work and protection channels follow different routes. At the receiving end the signal is selected from the work path or the protection path depending on the quality of the received signals, the protection state and the external commands.
