I think so, the kids and their long faces have disappeared into their bedrooms.

No more "is it working yet?" smile

Be nice, but I don't think the stats look promising.

Hub stats

Data rate:19.999 Mbps / 60.235 Mbps (presume that's sync?)
Maximum data rate:27.056 Mbps / 73.223 Mbps (what's this? theoretical max?)
Noise margin:16.0 / 6.3
Line attenuation:6.9 / 13.4
Signal attenuation:6.8 / 14.5

Speedtest is currently around 19 / 55Mb.

broadbandchecker.btwholesale.com says

VDSL Range A (Clean) 80 - 65.5 / 20 - 19 / 60
VDSL Range B (Impacted) 80 - 63.6 / 20 - 19 / 57.5

(down / up / handback)

Any improvement on 60 would be nice, but cab is approx. 250m away plus drop wire. Voice line back to exchange is probably around 6km. I'm guessing it's not going to get a lot better.

Huawei AIO cab serves a couple of dozen properties only. Will G.INP help in due course?

Another question, about the 'observed' figures on the broadbandchecker.btwholesale.com website. Are these accurate sync figures, as with ADSL? Neighbours lines I've looked at all seem to report 80/20.

Sorry, lots more info and lots more questions!

Another question...

Is there anything to be gained by replacing the old BT LJU5/1A (twin outlet) master socket?

Leave the line synced.
Try not to reboot or disconnect the modem if possible for the 1st week.

DLM will apply G.INP in the next few days if you are on a Huawei cabinet, increasing your sync speed.

In the days/weeks following that if the line is stable then DLM will lower the SNRM to increase sync further.

The max attainable rate you see is inaccurate and artificially high as Interleaving is enabled.

Thanks for that, I can see your sync improved considerably. Hopefully, I will see some improvement too.

This is all you can see on the Smart Hub 2 "Technical log" (current stats now)

DSL uptime:0 days,20 Hours24 Mins25 Secs
Data rate:19.999 Mbps / 60.235 Mbps
Maximum data rate:26.980 Mbps / 73.235 Mbps
Noise margin:15.9 / 6.3
Line attenuation:6.9 / 13.4
Signal attenuation:6.9 / 14.8
VLAN id:101
Upstream error control:Off
Downstream error control:Off

The rest of it is not relevent to the connection.

Thanks John, more good info.

I'm not touching anything for the next few weeks, let DLM do it's stuff.

Hopefully, no power cuts - we do get them occasionally out here in the sticks, fortunately rarely in summer.

I'm not sure how much it would affect FTTC, but the voice line back to the exchange is long. It is quiet though, at the moment - the lines are generally poor here, but I had a fault repaired on it a few months ago.

I was thinking about the LJU5 at some point in the future. It's an old one, double socket with the BT piper on it. Is there much to be gained by swapping it out for a NTE5A plus MK3 faceplate, or a NTE5C?
