ADSL2 or ADSL2+

[#1]

I'm pretty sure the reason you are on ADSL2 was given correctly by Jelv in reply #2, backed up by spraxyt in reply #3.

[#2]

That's a shame if true
Oh well, we may move sometime next year so will let SWMBO know what areas we can go to

[#3]

As has been said, it looks like some kind of noise issue.  But the loss you are seeing is extreme. I think it's worth asking PN to do some monitoring and testing of the line.
You should be getting more than that even on ADSL, never mind ADSL2+.
If you unplug the filter from the test socket, and plug a (preferably corded) phone into the test socket, what do you hear after dialling 17070 option 2?

[#4]

Mav, I think you began this thread by confusing cause with effect.  There is something slightly wrong with your line so the DLM in the telephone exchange has put you on ADSL2 rather than ADSL2+.  If you can fix the problem, which is presumably a lot of noise at higher frequencies, your line will perform better and you should find yourself on ADSL2+

Line appears to be quiet - couldn't hear any noise at all.
Still hoping one of the DC team will pick this up shortly and offer some insight or do whatever tests may be necessary.

Hi Mav,
On the off chance there I just ran a check on your phone line, and it showed a fault (Dis in exchange, I think this is the contacts somewhere). I've taken the liberty of raising this for you, hope it gets things sorted. I'll put the reference on a ticket on your account and pass it through to the phone faults team.

[#7]

Thanks Matt, appreciate you looking into it.

[#8]

Had a call from a BT engineer from the exchange a short while ago to say he couldn't find any problems and that all contacts were fine.
His explaination is that often the Dis fault is a false reading.
Is there anything else that can be checked/done?

[#9]

Well it does look like the connection is still dropping intermittently:

All we can do really if you've eliminated everything you can wiring and hardware wise is raise another fault or push back on the phone one. Just depends which has the issue or which you'd rather pursue it through I guess.

I've used three different routers over the last few of weeks plus new cables and filters.
The router is always plugged directly into the test socket at the master.
It appears, from my interpretation of the graph above, that twice the internet was down for several minutes.
The only drops actioned by me recently was when I connected the Homehub a couple of days ago and then powered down later the same day to change the socket the router was plugged into.
I got a resync around 3 hours and 20 minutes ago - latest stats:

What would you advise as to the next step.

[#11]

As I said above really. It seems you've checked about everything you can at your premises, so it needs pursuing as a fault - it's up to you whether that's done as a phone fault or broadband. There's a phone fault already open if you'd like us to pass it back for more investigation, alternatively you could run through the wizard at http://faults.plus.net which will pass a ticket through to our faults team to investigate it from the broadband side.

[#12]

I've raised a broadband fault using the link you provided.
Thanks Matt.

[#13]

On a good line with 43.5 dB of attenuation and a (presumed) 6dB target noise margin you would be looking to achieve downstream sync speeds of > 7000 kbps.

[#14]

Yes. But my fear is that BTO will deem my connection within their acceptable limits and do nothing.
I'm just hoping that the intermittent dropping can be rectified and, in doing so, increase the sync.
In my village all cables are overhead including electricity supply - not sure if that has anything to do with it but maybe...

[#15]

Something happened around 6pm today - didn't notice it till a few minutes ago, though...
The router re-synced at 6083 Down and 1024 Up and it appears it is now ADSL2+ from the stats below.

BT Speedtester is showing a profile of 5.37 so I'll have to wait for PN's to play catchup. The SNRM seems a tad low at 2.1 - was 3.5 earlier but I hope it remains stable
