I think this is one that only the mods can help with...and I doubt the helpdesk woud even understand what I was talking about!
My line was originally Ultimate Faster Broadband (i.e. FTTC but too far from the cabinet to be called Infinity) but now that service has been retired I'm officially on Unlimited Infinity (up to 52Mb) as of the beginning of this year. When the "switchover" happened there was no DLM reset - but I know the switch happened as the upstream IP profile went from 2Mb to 10Mb.
There are 3 NGA profiles that ISPs can specify for FTTC: speed, standard and stable. The majority of BT lines are believed to be on speed profile, although some seem to be on standard profile...and it appears to be those customers who also have BT TV.
Which is where the wierdness comes in. I don't have, and have never had, BT TV but my line appears to be on standard profile. How do I know? Because I monitor my line stats, and the DLM MTBE thresholds correspond to standard profile rather than speed profile. Specifically, DLM puts my line temporarily on high interleaving when daily ES goes over 1440 (but well below 2880) - the 3 occasions this year have been 1740, 1855 and 1539 ES during the course of a day.
I'd like my line to be on speed profile to reduce (and indeed based on my stats eliminate) the chances of my line being temporarily put on high interleaving because of 1 noisy day (generally a thunderstorm) and also to improve the chances of banding being raised as it's more likely I'll have a long enough run of "green" days.
How can I get my line put onto the BT default of speed profile? (which is what I'm paying for 🙂
Solved! Go to Solution.
@GW65 sorry about the delay getting back to you. BT Wholesale refer to these settings as Standard, Stable and Super Stable with the default being standard. They are not speed profiles but relate to how DLM manages the connection.
Unless someone has manually changed this its unlikely that you would be on anything else but standard but we'll be happy to check this for you. Please use the 'click here to contact the mods' link in my forum profile to send in your details, you'll can find the link by clicking on my username.
Sent my details to NeilO, and very shortly afterwards received a call from a(nother) very nice man at BT to say that my line had indeed been put on Stable profile at some point in the past so he'd just switched it to Standard and the change should take effect tomorrow. Many thanks to NeilO and the team!
