Both work, but neither are user configurable.
G.Vector (Vectoring) requires physical hardware to be installed on the DSLAM by the network operator and in the UK Openreach have only enabled on a tiny fraction of Huawei cabinets that were installed with BDUK funding.
G.INP is an error protection that is also controlled by the network operator.
In the UK G.INP should be available and enabled on all lines that are connected to Huawei cabinets.
The ECI cabinets do not have G.INP rolled out to them, excluding a few lines from previous trials.
