It didn't last time round.
The main problem was with the ECI modem, not so much the DSLAM.
I do think it will probably come with some sort of firmware upgrade, especially if there were issues on the DSLAM side.
According to hg612 modem stats the current chipset version is 0xb206
G.INP was working on both 0xb204 & 0xb206 I believe.
0xb206 is certainly the most recent ECI DSLAM firmware.
