Looks like 52mbps down and 10mbps up to me
What does speedtest.net give you? and what were you estimated when you ordered?
Also, everything from line 19 down is generally not required when diagnosing speeds / line faults. maybe best to not include it, just to keep the post length down?
80/20 FTTC with plusnet

I'm talking about the errors - there are masses?

Ahhh, got ya!
I'm not 100% sure on FTTC, but on ADSL I don't think the errors should be too much cause for concern unless the start to impact speed, cause resynces or cause DLM to interfere.
Do you have a BQM setup. that could be a handy way of seeing if packets are being dropped because of the errors

The DLM doesn't make any adjustments until the end of the day after the day of connection. Unless there is something major going wrong.
So you will probably see it has stepped in by Saturday morning. The full stats you have given are necessary if it has, to enable informed comment from the experts.
Do you happen to know whether the cabinet is a Huawei or an ECI?

At the moment, your downstream is operating with no Reed Solomon error correction (R is 0, indicating no redundancy) and no interleaving (D is 1). This would explain why you have nearly 39 minutes of downstream error seconds (ES of 2331) as the slightest disturbance in the downstream cannot be corrected. That said, I suspect the line is working reasonably well in practice.
As Bob says, DLM is slow to intervene on a new line.
I am not sure whether Openreach have ended their pause on rolling out G.INP profiles yet. If they have and you are on a Huawei cabinet, I expect that you'll get G.INP enabled within a few days. This enables some Reed Solomon in both directions and allows retransmission in the event of an error, meaning the higher layers in the network stack don't need to recover the situation.
If you're not on a Huawei cabinet or Openreach's pause on rolling out G.INP profiles is still in place, you may well see downstream Reed Solomon (R other than 0) and maybe a little interleaving (D greater than 1) within a few days.
There are others more expert than I in interpreting VDSL2 statistics and in the strategies employed by Openreach DLM.
|

|
|
It's a Huawei cabinet for certain.
Speeds, etc. are fine and the the SNRM will drop a little bit at night, maybe down to 5.2 from a max of about 6.8 - that's normal I'm guessing?
I'm just worried about the number of severe error seconds and CRCs.
I'm surprised G.INP isn't enabled as the cabinet was only installed about a month ago?
|
|
|
Which version of the HG612 unlocked firmware/software have you got? You need software V100R001C01B030SP08.
|
|
|
Openreach temporarily stopped putting people on G.INP profiles because of the additional latency experienced when the client device was not capable of bidirectional G.INP. A post today elsewhere on the forums implies that the Openreach trial of alternative G.INP profiles that mitigates this problem has been successful. That being the case, I suspect that the G.INP roll-out will restart shortly.
In other words, it may be a few weeks before you switch to G.INP, though I expect that switch to happen eventually. Make sure you have the B030SP08 firmware on your unlocked HG612, as earlier versions are not G.INP compatible.
Slight fluctuation in the SNR margin is normal, as on ADSL.

Stats are fine, within a few days you'll be put onto interleaved and you'll probably loose 2-5mbit of sync, until the ES are reduced to a minimum.
Enjoy your new service

The Reply button on the OP, that the rest of us used, might have sufficed  .

on the old DLM thresholds of 2880 ES/day that line will be interleaved within 2 days. Also the SES isnt pretty reading.
This is on the assumption the uptime is under 12 hours at the time of the post.

That was with 4 hours uptime.

My line is definitely not fine.
Take a look at the QLN and SNRM graphs for instance:

Could we see the current stats please?
Also are you using an unlocked HG612? If so then xdslcmd info --pbParams as well.

Only time for a quick glance. Two comments.
First you now have interleaving turned on. That typically costs around 10Mbps of Bearer 0 Downstream. But you've lost more than that.
Second, I'm surprised you have lost the complete top band of downstream in the medley phase of pbParams. That's the line showing what you are using as opposed to the discovery phase which just gives what is possibly available.
There are several others who know more, but it might be an idea to see what you get when going right back to basics. Which would be removing the faceplate and the VDSL filter plate and connecting using a dangly filter into the test socket.
If that's still bad then we need to start thinking of possible causes. If it's good, we have established something is dodgy on your premises.
I assume the whole lot isn't behind a TV or on top of/very close to something else electrical.

|
|
I've previously tried it through the test socket and it made no difference but I'll be happy to try again?
|
|
|
On Plusnet you can't tell the difference from speed tests, at least not until a few hours later. Only those two sets of stats.
|

Sorry I meant the stats were identical.
I'm not on Plusnet BTW
|
|
|
Sorry, I was mixing you up with someone else. But you no longer have TalkTalk in your sig .
As BatBoy says, it may still be an idea to let us see both sets of stats.
|
|
|
Okay that's no problem.
I'll do that in a few minutes and I'll post them up again
|
|
|
Sorry, I didn't get around to doing this last night. I'll do it at some point today.
Can I have the phone plugged into the microfilter?

The results are better with the phone disconnected as it rules the phone out as a problem.
|
|

No. Not for the duration of connecting the modem/router and taking the stats. Which takes less than three minutes - less time than you spend in the loo unable to answer the landline .
That raises another thought. I don't know if we have suggested the Quiet Line Test. Before connecting the modem/router to take the stats, try it. Dial 17070 Option 2 and listen for a couple of minutes. It should be silent. Then ring off and disconnect the phone and carry on.
The whole point is to remove as much as possible from the line, even if some things are not suspect. Some murderers are never suspected, but that doesn't mean they didn't do it.
After taking the stats, yes, fine, plug the phone in. That might be best in case we need another test in a day.

As I'm on TalkTalk LLU I don't get the BT quiet line test 
I have listened to the line and it seems to be clear.

ok so for me something is strange in the stats you are showing. The bearer and max stats look strange to me, specifically the upstream values. I would have thought the bearer would be less than the max. The same as download.
I assume someone will point out my mistake. One must be greater than the other for both download and upload.
Strange

Mine is similar on the downstream, and has been for months - through many re-sync's. # xdslcmd info --show
xdslcmd: ADSL driver and PHY status
Status: Showtime
Retrain Reason: 0
Last initialization procedure status: 0
Max: Upstream rate = 14428 Kbps, Downstream rate = 56760 Kbps
Bearer: 0, Upstream rate = 14182 Kbps, Downstream rate = 58162 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps
Link Power State: L0
Mode: VDSL2 Annex B
VDSL2 Profile: Profile 17a
TPS-TC: PTM Mode(0x0)
Trellis: U:ON /D:ON
Line Status: No Defect
Training Status: Showtime
Down Up
SNR (dB): 6.1 6.4
Attn(dB): 19.8 0.0
Pwr(dBm): 13.5 7.4 IIRC it is usually the unexpected way up on upstream as well.

Engineer came last week, all his tests pasts which didn't surprise me as the issue appears to be intermittent.
He went out in his van and found a big source of REIN just near my house and he tried to build a REIN case but couldn't as the interference doesn't seem to occur at any time of day, it's just always there. Coupled with the fact that the connection is quite stable (although erroring a lot in my view) meant he couldn't open a REIN case.
TalkTalk are being quite useless, they just want to close the fault. I don't think they're going to be much help (they lack proper line testing tools, historical line data, etc.) so I think we'll be moving to Plusnet.

Still having issues...

Getting absolutely nowhere with this.
The connection is stable yes but the performance just seems to be so meh!
Hlog still looks bizarre: http://imgur.com/rT9BhD4
