I recently had a fault with my line and a Openreach Enginner vsisted. A wiring fault was found in the cabinet down the road. My line stats are now much improved, but I'm seem to be stuck on a reduced profile which was a result of the previous poor line quaility.
I asked the Engineer about doing a DLM reset to get me be back on a Open Profile. He said this would be done, but so far this does not seem to have happened. The modem has had no dropped conections since his visit.
How can I get the DLM reset?
You could be waiting a long time if your line has been banded. I've yet to see evidence of DLM removing banding once imposed.
It does seem a rediculios system!
One minute I'm getting just below 40/10, now I'm on 25/5!
There's nothoing wrong with my equipment or wiring, but a fault in the Openreach network and now the DLM has permanelty applied the wrong banding.
Surely it's not his bad?
My line was banded in early March due to unexplained instability on my line which disappeared as fast as it came. I am still banded despite a DLM reset that was performed when I upgraded to the 55/10 product in April. There appears to be 2 levels of DLM reset, one of which does not remove banding.
I had a line fault about a month ago which entailed several engineer callouts and resulted in a banded profile. Contacted UK BT live chat and sent out a 'broadband boost engineer' next day. Engineers aren't normally dispatched just for DLM resets however I suppose it helped that I had an existing fault reference.
Do note the engineer requested a DLM reset at my premises whilst on his mobile, the first attempt didn't increase sync much, still was stuck. On the 2nd attempt it actually took someone at the DCoE to arrange a physical disconnect and reconnect of my line card for DLM to fully reset.
