Yeah looks like one step of one way interleaving (7/8ms). Interleaving both ways would be +15/16ms. Oddly again my line with 8dB SNRM has an uptime of 60 days while my mate's line with a SNRM of 25 resets every two or three...

Strange seeing as im right by the cabinet, about 50 metres of copper

Pretty much the same for my mate in Aberdeen, 40m straight line from the cab, about 60-70m copper, but line keeps resetting whereas my ~350m equivalent line never does...

you also need to be lucky on noise interference etc. as well.

Me and my friend both had equal attenuation and also almost equal attainable sync rates.

There was 2 key differences tho.

His line was underground right up to the property, mine was overhead on pole.
I am in a dense city area, he was in a business park in the middle of nowhere.

His line performed consistently had little crc errors, drops etc. and ran fine on a low SNRM on fast path, it also had less fluctuation during the night.

Mine had noise bursts during office hours, lost a lot of SNR at night making it require extra SNR or interleaving for stability or even both. I could keep it on fast path with SRA. Also even when things seemed healthy SNR wise, I had a constant flow of CRC errors 24/7. Through experimentation when I had full control of SNRM on my router the crc errors only stopped with a 24db SNRM. Even then they didnt completely stopped but were comparable to others with a 6db SNRM.

So even when I get FTTC I may still get issues.

well im about 50m from the cab, and as I mentioned here

im getting frequent disconnections

noise interference.

new isnt brand new.

and you can quite easily get interference.

other things it could be are modem fault, or cabinet equipment fault, cable fault.

just got my samknows broadband report.
