I take it all who have seen G.INP being enabled on a ECI cabinet are using the HG612 or compatible modem with telnet rather than a ECI modem locked or HH5A as they won't show up the G.INP data.
My question will G.INP work on an ECI cabinet with a ECI modem or a HH5A
I saw increases in speed with both the ECI Modem and HH5a, no way to tell 100% unless you have a unlocked ECI modem however.
HG612 before G.INP = 60mbps
HH5a before G.INP = 62mbps
HG612 after G.INP = 62mbps
HH5a after G.INP = 65mbps
Was constantly in that range before G.INP, so unless G.INp got rid of a fair amount of noise it seems to be active on the HH5a.
I've also swapped between all three with G.INP always being shown as active on the HG612.
