I am curious. If 504X is duty 1 and if that swop between 504X
and 477R meant TIB477R takes 960-1, Who is SMB270Y
replacing?
If I'm not wrong, SMB270Y is [WL SP/960], just like TIB525K [WL
TRG/960/SP] last time, it'll appear on 960 replacing one of the
respective rigid perm that isn't on 960...
SMB270Y was perm 960 long ago, which might be the reason why
after it was known to be SP for now, the deployer will prefer to
make it easy for it to be back on 960 to cover for a number of
days/weeks... I would think it's WL SP/960...
