We unfortunately don't have the ongoing stats for the first few days i.e. from when DS sync speed was 9999 Kbps against an attainable rate of only 25208 Kbps, but I have attached the montage for the ongoing data collected since 24th January along with an animated gif file including today's snapshot data to show how the connection's speed is gradually improving.
I'm not 100% sure that G.INP will be implemented.
The DSLAM is Huawei:-
ChipSet Vendor Id: BDCM:0xa48c
ChipSet VersionNumber: 0xa48c
However, I have seen a couple of other connections using chipset version 0xa48c where G.INP didn't seem to be implemented.
FWIW, this particular chipset has fewer tones available at Discovery phase when compared against the 'usual/older' chipset version.
0xa48c:-
Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3959)
Older version 0xa459 (as per my own connection):-
Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3970)
