OOS overheads are optical-layer overheads. Which of the following statements about OOS overheads is false?

After GE services enter the client side of an OUT board that supports Ethernet services, they are encapsulated into OTN or SDH signals by the signal processing module. The alarm signals are processed in the same way between encapsulation into OTN signals and encapsulation into SDH signals.
