looking like 400-500 errors for 24 hours, so about 400% increase for a drop from 7.1db to 6.4db.  a 1/4 tho of what I had before the 7th so easily within thresholds.

BT have told plusnet they fixed the network fault, obviously I have bounced it back to plusnet given my sync speed is now lower and I have a new water ingress fault and plusnet stating they need to do a live chat with BT to book an engineer with me thinking why didnt they do this 2 weeks ago? dragging their feet.

Considerably better results than me (in regards to errors) when I was on Fastpath with no sync cap in place. Just out of curiousity, is your DSLAM an ECI or Huawei?

[Chrysalis]

ECI

Just having a shifty Chysalis it would appear the residential DLM has a 14 day recovery period on FTTC and Business FTTC has a 24 Hour recovery period if bursts of errors have been seen, so there you go the DLM can be configured if you have the extra wonka to spare.

I'm on business FTTC yet I don't get this recovery time (I'm around 14 days as well). Odd.

another line change today, this time an improvement so its now 1mbit below the attainable I had before the problems.

this has me now back on a snrm above 7db.

[Chrysalis]

This situation I give some sympathy to openreach engineers, I expect to help their diagnosis they should be attending a fault in a timely manner after the fault happens, yet plusnet are still delaying due to some kind of mismatch they say exists on BTw's db, claiming is absolutely no escalation/overide process.

The last 2 days the problem is past its worst meaning if an engineer were to attend now they may state I am too close to the estimate to be worth bothering with which makes me angry, but the line is still not stabilised, the snrm is jumping up and down between 6.4-7.3 db so attainable jumping between 62.4mbit and 65.5mbit like a switch is been flicked.

I find it very hard to believe that a organisation as big as BT would not have a overide system in place for booking engineers (as after all how was engineer dispatched for this "network fault".  I feel this is just plusnet applying delaying tactics to avoid possible engineer fees and hoping its a DLM issue that recovers itself.

Cheers I must have pick that information up wrongly, what are the benefits from being on a Business line compared to residential as never used one.

[Chrysalis]

I think the benefits are as follows.

Higher priority on bandwidth.  BT wholesale have a minimum speed thats expected under heavy congestionn, business lines have a higher minimum speed, 50% higher.  They also have higher priority so eg. under light congestion they should be faster as well.  However the reality is congestion is now uncommon on BT's 21CN network.  Bear in mind I believe there is no priority system on openreach cabinet backhaul.  Just for BTw.

The option of having higher priority fault resolution, I am not sure on this but I think there is effectively 3 grades.  Residential, business, and business with a addon.  I think residential lines cannot buy this addon.  I am defenitly not sure on this tho, I have not googled to verify it.

Isp's themselves may add benefits, eg. plusnet have a dedicated business support team and business customers jump the call queues.

Business lines (isp side) usually allow commercial use whilst residential do not.

Many thanks Chrysalis for the information, and I have never done any research into Business BB before, on a certain forum I said it was 14 days for the DLM to recover and the expert said no it's 24 hours as the OP is a business user so i left it like that

Phew, for a moment I thought someone had bodged my type of order up lol, as I'm still interleaved despite the minimal errors lol. I get higher priority traffic when congested (never seen this happen though) and a quicker repair time.

[Chrysalis]

by the way guys, my samknows data is very interesting during my interleaved period.  will post screenshot soon.

[burakkucat]

That is throughput speed data, isn't it?

I would be interesting to see the "Eagle" data for the corresponding period and to compare the line's relevant statistics.

[Chrysalis]

yep thats speedtest results to samknows.  the throughput nosedived big time, the sync speed didnt get that low.

Sorry, but this is all the throughput data I have since 1st January (via Speedtest.net):-

Although latency is a shade high (I have seen it as low as 5MS when Interleaving was turned off), I have never suffered from reduced throughput speeds, even when my connection was able to sync at around 30 Mbps+

Througput has almost always been around 94% of IP Profile or higher.
