I've got a problem with my ONS system. As you can see in the figure, the first one is CTC view of Node1 and the second one is Node2.
In LINEAR model, side B of Node1 connect to side A of Node2. But take a look at them, side B of Node1 is working normally, no alarm. But side A of node 2 is RED with Los of signal alarm.
My traffic is still working good between 2 Node. It is so strange, I have never been experienced the error like this before. Please tell me what this situation is? Thank you very much.
