      Just been given a manual profile - what about DLM?

      Hello all

      I joined Sky recently and was activated for broadband unlimited on Monday. I am an ex-o2 customer so i'm new to DLM and how sky work. I have their latest sky hub SR101 i think it is referred to.

      I have been having some very slow speeds, 1 download i did earlier fell to 80KB/Sec. My DLM started monday at 4Mbps / 29.5dB DS-Attenuation / 15.4dB SNR. 2am it resynced to 7Mbit at 9dB. However the speed were very poor. It took ages to get a Netflix HD stream, it seemed terrible considering it was connected at 7000Kbps.

      Anyway i called them up and they suggested they reset my profile to a higher speed. She adjusted the line to 16Mbit and it synced at 15.3Mbit and 7.6dB. I believe this was an exception and a manual remotely set profile.

      Because it is a manual profile, what happens now? Does my DLM carry on now. I am hoping it will realise my line is stable and noise is low and lowered my SNR to 3dB for a higher sync. I ran at 3dB with o2 rock solid with no disconnects. So i'm hoping that manual profile doesn't lock it at 7dB.

      Also does DLM mess with g.iNP and fast path as my pings are current 28-31 where as o2 was 19-22.

      I'm not sure if i'm connected to the DSLAM equipment. I am LLU but i read DSLAM equipment is the only equipment with the new DLM and management for better speeds and pings.

      Not sure if you can tell by my tracert.

      Ignore my ping spikes. My Haswell Mac has some funny power management which effects pings on anything other than demanding streams.

      If i set the ping interval to 0.1sec i get

      Re: Just been given a manual profile - what about DLM?

      The agent should have re-activated DLM and restarted stabilization after changing the profile. If not, DLM will come back on automatically after 2 weeks, but if it's stable then nothing else will happen.

      It's difficult to tell whether or not you're on an ISAM, which can be set to 3db manually. Both DSLAMs and ISAMs can be set to 3db by DLM
      DLM doesn't control g.INP as far as I know, and Sky don't support fastpath.
