Re: VCAT/LCAS

I support this work.

When we consider the requirements in section 3, do we also need to consider the scenario which the Ethernet service is supported by Xc or by the combination of Xc and Xv?

Another scenario is if we have the optional Xc and Xv flexible adapatations at both ends, does the signaling need to support the selection?
