Hi,
Some of you may remember my ramblings about how long it was taking for G.Inp to be reinstated, as it is a pre requisite for xdB (and the increased speed that a it brings). It finally got added back a month or so ago.
My Line normally syncs between 72 and 75 Mb. If I can jump on before anybody else, after a power cut, I can often squeeze 77Mb at about 3db snrm once everybody else comes back online. My downstream snrm varies by a db or two in single steps, up and down, once or twice a day. I presume this is a single disturbing line or some other form of crosstalk causing interference being switched on and off.
About a week ago, we were having heavy storms. I looked at my connection and saw that downstream snrm was much higher than usual, around 8dB, and my attainable was huge too, around 86Mb (Normally 76 or so) - I assumed a bunch of other people had been knocked offline by the storm, so did a resync to grab the extra speed.
What has happened since is the strangest part. I'm still synced at 80Mb, still have a downstream snrm of 6, and still have an attainable of around 86Mb. If it was storm related I'd assume that my snrm would drop as the other users came back online. The only difference in my stats that I can see is that my downstream interleave has gone from 8 to 16. Would this give me all the extra bandwidth/attainable etc? I've attached telnet data from before and after the resync if anybody can explain what might be happening to me.
Thanks.
Andy.
