The thing that freaked him out somewhat was that there were no errors at all on any of the counters on the JDSU. None. He thought the test head had gone again
I can't remember the dB/Hz reading he got for noise but it seemed somewhat remarkable to him.
He re-ran the test and got one FEC but that was probably one of the kids turning on the light/extractor fan in the bathroom.
I'm fairly astonished at the noise margins TBH. Wasn't expecting 20dB on both by any means - as I said to you if there's going to be issues then it will be on upstream. Guess I got the mains filtering nailed down tight
Re the ADSL v1.0 failures - doubt this was one as it held 21Mbps @ 3dB with an average of 10 CRCs/day. Ignore that bit, misread your post. I think the extra chokes in the latest version of the VDSL faceplate are there for POTS reasons and not REIN. Might give it a few months until they appear consistently online and buy one, have a play and see what the chokes are for.
Re xtalk - its a big PCP, 2x140 (144 surely?) pair cables to FTTC cabinet. Large Virgin presence around here though - mainly due to BT leaving it late on everything from 256kbps ADSL to FTTC. Always amazes me that Braunstone/New Parks (large and very unpleasant council sink estates) got everything from BT before an area like Glenfield which although nearby has a shedload more "disposable income". Virgin, Sky, Be, TalkTalk - they all worked that out years before BT did/does. Eg the next-door neighbour could only get 2Mbps from BT for 3 or 4 years while I had ADSL2+ from Be and then UKOnline (Easynet). tl;dr is I dunno, anyone who wanted "superfast" around here has probably long since moved to Virgin but they may come back now.
The problem for me in measuring attainable rate is this Sky router which does auth via MER. I may summon up the will to do something about that but frankly most of the VDSL2 kit on the market in the UK looks garbage in terms of specs. Fritzbox stuff is solid (7 year warranty/upgrades helps) and I see Draytek still have their fans - and garbage support for anything meaningful. I'll probably do what I did when I first joined Sky - use their kit for a few months then see what's around/what I can be bothered doing.
BTOR SFI was very impressed with some of the stats you guys are pulling out of unlocked BTOR modems - I showed him one and said look at the peaks on the QLN graph, in that case they were radio stations but they could just as easily be local REIN, so you know what to tune to when you're doing a walkabout. I pointed out to him that the usual "tune to 612kHz" advice isn't decent for VDSL - need a small shortwave radio that covers all the way up to the 16m band, or 17.9MHz for those of you who don't have a radio background. Needle in a haystack time unless you can see real-time graphs.
