On a Huawei cabinet here,with a HG612, & I just had major work done on my line,finally got rid of the aluminum cable,
gone from 9Mb to 65MB, been up four days & I'm still waiting for a resync to see if speed creeps up a bit.
I now find G.INP is no longer active on my line.
, So , I presume it's G.INP MK2 has kicked in, which is a shame, as with G.INP MK1, I was getting around a extra 6Mb plus with it.
