That appears to still be on an old ADSL MAX service (8128/448) Which shouldl give a BRAS of 7.5mbit.
Looks like your connecting with G.DMT still - so you either have not been uplifted onto 21CN. Your on a 12dB margin and it looks like the line should be good for anything upto about 18mbit on ADSL2+ (Subject to DLC etc)
If you have been uplifted onto the 21CN service you need to select 'Multi mode' for the modulation type (Easiest)
You also may want to look at using PPPoA as your router is reporting PPPoE which will want a lower MTU.
Nothing will change for weeks if you leave it to DLM - best thing to do will be give Tech Support a call ask them to reset your noise margin back to the default 6dB, and interleaving off (If you think your line is good with no interference/noise)
You can also check with them or via the portal if your on a 21CN service or an old service still.
Hope this helps.
