Re: DLM - why?
I think it is because someone has read that in theory it should increase the speed on long lines. The trouble is that the theory seldom works in practice. I think Sky have a problem in that if they don't try it on long lines the user on the line may be miffed at not getting a chance at the 'high-speed broadband' Sky have promised. It would help a lot if these long lines were monitored and returned to G.DMT as soon as ADSL2+ proved a failure. Unfortunately the user is often left trying to convince someone in Tier 1, who does not understand the problem, that something is wrong.

Re: DLM - why?
I think I may have had a "result"!
I sent an email to Sky saying:
On 21/10/09, amoung other things I said
"So, can you confirm that my target SNR is 7db for both up and down and that there is no limit (up to 20Mb down and 1.3Mb up) on my rates?"
but no-one has even bothered to reply which is very disappointing.
At present my download sync is the usual 18493kbps while my SNR is 9db. No amount of rebooting the router will obtain a higher sync rate with corresponding drop in SNR. This would indicate you've capped my line at 18493kbps. Please can you uncap it and set it at the 20Mb you advertise. As previously requested, please can you set my upload cap at 1.3mb as you advertise.
I have as requested set your line at 20Mbps up and 1.3 Mbps, Target SNR set to 7db up and 7db down. Please note this may make your line unstable as in its current condition it is not able to handle the full speed. If packet loss now occurs and you would prefer to have the line capped to a speed which is attainable.
Please reply this email and we will revert to the 18Mbps, which your line was previously set at to ensure a stable connection.
