Based on page 6 of the 'G.INP BT rollout 2015' thread, it's been established that the default G.INP config on a HG612 is 'off/on' for upstream and downstream respectively, suggesting that G.INP will not be available on the upstream channel unless enabled. Is this likely to be the case, and if so would there be any benefit in changing it to 'on/on'?
Also how would that be achieved?
