Ahh so thats why you avoiding broadcom, as I was going to ask.
Everyone here is in a better position to help if you active on MDWS.
The problem you will have with openreach is they consider interleaving to be a "solution" not a "workaround/mask". So unless interleaving pulls a line below the handback threshold they will consider it all good, so now you going to be reliant on AAISP fighting your case to tell openreach thats not acceptable.
In my opinion the error rate you previously reported is way excessive, getting 1000s even in a single hour, however if the line is stable when interleaved, from a dumbed down view point openreach may just say its working as described and then refuse to do anything. So aaisp will need to keep pushing them probably.
Did you tell aaisp about what you was told by your installation engineer?
I know, problem is I noticed I got blips of packet loss of 1% occurring every so often on the AAISP CQM when using the HG612. Now I have 'R: 16' (FEC) on the downstream, assuming the HG612 doesn't change that, I could put that HG612 back on perhaps late tonight and try it again. I wish there was a way for Lantiq chipsets to work on MDWS as they just seem to work a bit better with my line. On the ECI /r with LEDE on the latest firmware I'm sure I recall getting around 75Mbps down, where on the HG612 I believe it was previously 69Mbps when it was 'R: 0', and of course almost none of the intermittent blips of 1% packet loss showing on AAISP's CQM when using a Lantiq chipset.
Yes I told AAISP about it, and I also told the engineer today but the engineer (who I found out was an SFI engineer) said if there was a problem with water as the previous engineer mentioned then there would be a noticeable issue on the voice side. Given the periodic bad weather here it should've been noticeable. However he did say that it might be there's no or very few spare pairs which are working correctly and could be why they mentioned it as it is something that still needs doing but isn't affecting your pair at the moment.
Here's my latest stats (

Here's the bitloading chart from the DrayTek too:

AAISP appear to want to keep the fault ticket open for now and let more time pass to get more statistics. Last I checked on the control panel they're scheduled to discuss this with me again on or by Monday.
EDIT: Oh, forgot to mention that the engineer didn't seem too keen for me to use the ECI /r or HG612. He called them old and probably don't sync as well as more modern modems do. I did mention however that they were used as more proof that it's not my own equipment.
