So, the correct answer should be A) ATS because it's the signal transmitted in that direction for maintenance purposes.

You're correct, Leslie. LCK is also a maintenance signal, but it's not transmitted from downstream to upstream.

But isn't LCK also a maintenance signal in OTN? I think it's B) LCK.
