I've got a Huawei cabinet so let me know if you want anything testing in regards to G.INP (it is currently disabled but I expect will be turned back on soon).
Would you be able to test this test image if you have G.INP re-enabled?
On this image G.INP is allowed on the upstream but I have no idea if it works properly. I think the hardware is capable of it though. I'm not sure which version of ECI /r you have so I've just built images for the two, and if it works it can replace the current images linked at the start of the topic.
Others with Huawei cabs feel free to test too
In a previous post I said I noticed bitswap was off but now I notice it turns itself on but only on upstream, is this normal behaviour? does the cab turn it off when it's not needed? I'm going to leave this setup for about a week and monitor any changes.
When using the HG612 bitswap was always on and I find it strange. Perhaps the cab is talking to something in the lantiq code.
