      These Pings/Tracerts Ok ? Would I benefit from the gaming profile ?

      As per the title really, theres 3 Xbox's currently connected to this line & we're all avid gamers. We're currently using a US DGND3300 (Sourced it cheap, hence the US Version), the line is PPoA so no problems connecting using the user/password generated using the tool here. Anyways we have a fairly stable & fast connection so just wondering if we'd benefit from the gaming profile. My stats as follows.

      We've just had one problem since switching to the netgear router, it will sometimes drop the internet connection (the light goes out on the router) but it doesnt actually drop the connection as far as I can tell (the stats don't show a drop in uptime), any ideas what that could be ? We'll go back to the Sagem if it continues.

      So, what do you think ?

      Thanks & Regards,

      Re: These Pings/Tracerts Ok ? Would I benefit from the gaming profile ?

      You might benefit from a gamer profile, but it would not be by a great deal, maybe 4-5 ms. Your download would reduce to 20Mb(19999kbps) so it is really up to you whether you want to sacrifice some speed for a better ping. It would have the side effect of making your connection even more stable.

      As to why the light is going out on your router, it could just be a bad joint to the LED. If it is not actually disconnecting, don't worry about it. It is a far better router than the Sagem.

      Re: These Pings/Tracerts Ok ? Would I benefit from the gaming profile ?

      Although it doesn't apply to my line, i was wondering about this.

      Yes, there is a specific 19999 / 1215(ish) gamer profile, which because it can only be configured manually, results in a target downstream noise margin of 7db, hence the greater stability.

      However, 8ms max delays (which apparently is all the gamer profile actually does) can be applied to ANY 'service' (standard, non-gamer) profile.

      So my question is, can 8ms max delays be applied to a line that DLM has previously profiled above 20mbps & with a target noise margin below 7db, without the associated speed loss that the specific gamer profile would result in?

      Edit: Re-read. Yes, there are a few 8ms 'service' profiles, which differ in no way from the 'gamer' profiles.

      DSLAM - Yes.
      ISAM - No.

      Both you can see all the settings in front of you. Downstream rates, delays etc. To change them:

      DSLAM deals in drop down menus. Click the 'suspend DLM' button and go to town on the drop-downs and it won't affect the target SNR / other settings set by DLM, unless you manually do.

      ISAM is different and harder to explain. Click the 'suspend DLM' button and then you have the option to click 'change profile'. You're presented with a drop down to choose SNRs e.g. 7/7, 9/7 all the way to 15dB. You can't manually choose lower. Then, the next drop down -

      Service profile - It opens up a graph with radio buttons. See below for details.
      Gamer profile - Only a choice of 4 in total if I recall. Pre-set with 8ms delays e.g. 1024/256, 2046/416, 10240/800, 20000/1216. You select 'save' and it'll reprofile to what you chose.

      The graph shows sync speeds up the y-axis and INP on the x-axis. There are very, very limited amounts of sync rates to choose from. To put it into perspective:

      1024/256, 2048/416, 3072/256, 4096/416, 4608/864, 8000/768, 8192/864, 10240/608, 16384/768, 18016/1216, 20000/1216 - welcome to most of the profiles available to be chosen. Ever wonder why some customer's upstreams are capped down when they ring up to have the line reprofiled? The shoddy amount of choice, that's why.

      There are a couple of different INP values for each profile above, some with only one option as to what symbol you choose e.g. 3072/256 only has 2 symbol INP with 16ms delays, whereas 4608/864 is 0 INP and 8ms delays and 4096/416 either has 1 INP or 2 INP etc. to whatever you select. Each profile has pre-set delays. Some do have 8ms delays.

      Point is, when you click on the radio button and then save it, it completely reprofiles to what you have chosen. You can't pick and choose with ISAMs, at least on the GUI that most at Sky would be working with. You choose the radio button and whatever settings are attributed to it, that's what will be chosen. You CANNOT just choose to change upstreams, delays etc. like you can with the Easynet stingers. For example: There is a 22/1.2 profile 16ms delays, which the OP seems to be on. Only choice if you want 8ms delays is to cap to the 20000/1216 profile.

      Who said this?
      I thought you did ,lol

      You made a great post a month or two ago, effectively giving an overview of the above, but after several attempts i've been unable to find it again. grr.

      CST also told me that 8ms max delays can be set to any "normal profile"

      Haha, I edited the post after I re-read it.

      Should be this one here.

      I remember slightly hijacking one of your last threads, which I apologise for, but there were a lot of incorrect statements made by one member in particular and it just complicates things further when others read such inconsistencies.
