As far as I know the HH5A and the ECI modem pre-date the amendment to SIN 498 for G.INP
They do, as does the HG612. Which is why they had to roll out f/w updates in order to comply with SIN498.
I spoke to Ian in person for the best part of and hour in
Jun 2015 and it was during this convo I asked if he would be prepared to put his name to some of the questions asked by our community in print. I also asked about ECI cabs, but he would not be drawn on the topic of upstream g.inp or vectoring.
Didnt manage to get permission to print anything until Aug 2015 as it had to be double checked and there was also a couple of other events that got in the way.

PS the specific reason I wanted it in print is because then there could be no doubt about some facts that I'd already been told.
