In this case, is there any alarm reported inside the SDH network?

Network elements A, B, and C are OSN 3500s that form a chain network. The two AIC stations are connected to routers. The IPR router is connected to the OptiX SDH equipment through the STM-1 POS port. The PAS port also uses 1 and C2 bytes as payload transfer bytes (for carrying services). VC4 services are created from network element A to network element C, and VC4 is passed through network element B.
