Upstream slow after line maintenance


[link to this post]
 
Hello All
I'm really hoping that someone can help shed light on this for me as its being driving me crazy for the last month.

I'm using a billion 8800 nl.

Up until last month i was getting a reliable 22 meg down and 1.2 meg up.
Something happened which required an Openreach engineer to repair the line in one of the manholes under the road.

Since the "repair" my downstream has returned to the previous speed but the upstream hasn't.

Checking the stats and i can see that the upstream SNRm has gone from around 6.9 to 16.3.

Attainable rate is 11397 Kbps. Actual is 797 Kbps.

Upstream G.INP has changed to 0.

I have to go through Sky to get to Openreach but they are totally useless and don't seem to understand what i'm asking.
As far as they are concerned its fine as its above their minimum figure.

Does anyone have any suggestions as to how to proceed with getting this looked at?
As downstream is fine and its only the upstream affected is it likely a problem at the equipment end?

I'm signed up to https://www.mydslwebstats.co.uk under the username of bofh5

Many thanks

Banded profile.

DLM should relent in time.

I had a DLM reset carried out by an engineer but it made no difference.
Is it possible the upstream has been capped as the BT ADSL checker shows 0.8 as the low upstream for a clean range ?
Thx

Providers often say a DLM reset has been done, but in reality it has not.

The checker is not the source of any capping, but the banding may well be

Comparing your line to others on MDSLWS your U2 band is absent; it would have been preferable to have some before stats on MDSLWS.

They have been less than helpful
I still think that the upstream SNRm going from 6-7 up to 16 is a sign that something isn't right.
I was reading another thread where someone else had a similar issue with the upstreamm
Unfortunately it fixed itself so don't know if it was suspected interference or not.
I really want to get a BTOR engineer out to check the connection at the DP then at the master socket but you know how hard that it frown

Not really, if anything is shows your line has been improved but the banding is still in place.

If that margin was to reduce to 6 (via a true DLM reset initiated by an engineer)then you should see quite an improvement on the upstream sync speed.
