I wonder, have your Discovery phase band plans changed at all?
These are mine:-
Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3970)
But I have seen some other users, also on Huawei DSLAMS with these band plans:-
Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3959)
Here's a recent example from carlmagic, the only user with stats that confirm that G.INP has been enabled that I am aware of:-
