Line Stats
JamesK:
Hi All,
Further to my previous post I've just had my line moved from an ECI to Huawei cabinet. Straight away my line speeds were better than with the ECI, with the line syncing at 38mb. Almost exactly 48 hours after the line was activated, it resync'd, and enabled G.Inp. My stats now show the line speed as being nearly 44mb. However, speed tests are still showing speeds of around 36 which I was surprised about.
Can anyone tell me if this is normal, and if the line stats below look good? Attached a few pics from DSLstats as well. At the moment I'm still using the HG612, but plan on swapping this out for a VMG1312-B10A over the next few days.

A few more graphs added
underzone:
Just wait another 48hrs, you should get 5dB from DLM. Then another 48hrs later 4dB etc... until you get 3dB.
Then check your IP/BRAS profile and if needs be: leave your modem & router off overnight.
Next morning you can power up and you will still be on 3dB with a matching IP/BRAS profile.
Just be patient for now though, let DLM work its magic.

Out of interest what were the sync figures on the ECI cabinet with fastpath?
Do you have a copy of the ECI bitloading? Is it the same pair?
With my change from ECI to Huawei, on the same pair...
ECI
Fastpath/6dB: 55 down 6.8 up
Huawei
Fastpath/6dB: 54 down 11 up
Upstream was the biggest initial gain for me with the Huawei performing MUCH better.
3dB didn't come along till after crosstalk did its work on my line and knocked me down under 40Mb.
I'm currently synced at 45Mb @ 3dB
I was the very 1st line on my Huawei, which was added as our ECI was full.
It's no surprise I lost 18Mb to crosstalk (3dB gave me 8Mb back so overall I'm 10Mb down) as the Huawei cabinet filled very quickly.
It now has an HD expansion after less than 18 months.
The ECI took 4 years to fill.

I didn't think to take a copy of the ECI stats before the line ceased. I really should've done. However, I found some historical data I kept from a couple of years ago, and the upstream/downstream rates remained static for the last few years. The comparison is as follows:
ECI
Fastpath/6dB: 38 down 9 up
Huawei
G.Inp/6dB: 44 down 11 up
So, in my case there's definite improvement in the upstream and downstream. But previously the ECI never sync'd at over 9 on the upstream, even when first installed in 2012.
Two OR engineers visited on the day of activation. The 1st had an apprentice with him, and prepared a 2nd line, and did the work at the cabinet. He said he needed a "UG engineer" to complete the work as he wasn't allowed to finish the job due to having the apprentice with him. When the 2nd engineer turned up, he just used my original line (no idea why). According to him I am the only person connected to the Huawei at present. I'd be surprised if this cabinet filled quickly. It took 6 years for ECI cabinet to fill. They've installed a large Huawei cabinet... so maybe there is the demand, or maybe there's a plan to decom the ECI.
I've run a speed test this morning, and I'm now getting nearly 41mb. I haven't seen speeds like that since the ECI cabinet first went live in 2012. The absolute maximum I managed to get was 42/43mb and that soon dropped as the cabinet filled up.
There's been no further DLM interventions overnight.
