For no reason other than curiosity, I wanted to check if G.INP is enabled on my line. Looking at the stats from my HG612, it looks like it's enabled on the downstream, but I can't tell if it's enabled upstream too. I'm pretty sure my cabinet is a Huawei, so am I right in saying I should have G.INP upstream too?
These are the stats from the modem (I haven't posted the whole log as it's quite long).
Thanks for any advice.

I can't answer your specific question but G.INP on upstream has a mind of its own
Mine changes from enabled to disabled for no apparent reason as well as upstream interleaving
this link gives a bit of background with stats for my connection http://forum.kitz.co.uk/index.php/topic,20557.msg360399.html#msg360399

From many posts on this and the kitz forums plus my personal experience, my take on G.Inp (retransmission) is:
DS G.Inp is applied to all VDSL2 lines (eventually) by default provided the DSLAM (fibre cabinet) is Huawei and a G.Inp compatable modem is in service.
Your Huawei HG612 should be G.Inp enabled for both DS and US service.
Very, very few people currently have DS G.Inp enabled on ECI DSLAM's as there is a long standing and still ongoing issue with software compatability, testing of revised software was postponed by BT just before Xmas, see kitz forum.
US G.Inp is not applied by default but can be applied by BTw DLM should it be deemed necessary due to line quality issues, excessive errors etc, again only on Huawei DSLAM's attached to compatable modems, some modems are only G.Inp compatable in DS direction, I believe the PN Hub 1 (re-badged BT HH5a) falls into this catagory.
In my case, I waited close to 8 weeks for DS G.Inp to be applied by DLM after migration from ADSL to fibre, US G.Inp has never been applied to date, don't think it ever will as my US error rate is very low, not required.
Again, from forums, very few people report active US G.Inp on their lines.

Ironically enough, this post has just appeared on the kitz forum relating to US G.Inp, may find it interesting.
