BT Voyager 2110 stats

Could someone help me understand modem my stats please? My Voyager 2110 reports the following:

Line Mode G.DMT Line State Show Time
Latency Type Interleave Line Up Time 00:13:04:15
Line Coding Trellis On Line Up Count 1

Statistics Downstream Upstream
Line Rate 7872 Kbps 448 Kbps
Noise Margin 9.9 dB 21.0 dB
Line Attenuation 38.0 dB 20.0 dB
Output Power 19.8 dBm 11.5 dBm
K (number of bytes in DMT frame) 247 15
R (number of check bytes in RS code word) 8 8
S (RS code word size in DMT frame) 1 8
D (interleaver depth) 32 4
Super Frames 2712331 2712329
Super Frame Errors 225 0
RS Words 184438538 23054796
RS Correctable Errors 1969903 18
RS Uncorrectable Errors 2358 0
HEC Errors 178 0
OCD Errors 0 0
LCD Errors 0 0
ES Errors 0 0
I understand the line rate, margin and attenuation(I believe). Output power I'm not sure about and I don't think I care about the KRS & D figures. I assume the Super Frames is a measure of how much I've downloaded today - just light browsing - after that it gets worrying. I've no idea what constitutes 'normal'. The super frame error rate seem nice and low - about 1 in 10000, but the RS correctable error rate worries me. This morning the rate was more like 1 in 10000, but it is now about 1% and getting higher as I type Sad I already suspect I have noise on the line from the behaviour of my netgear DG834G which reported a highly vaiable noise margin - but I'm not sure how reliable it is which is why I bought the voyager from eBay to compare. Do I have a noise problem that the voyager modem is handling better? The netgear used to lose sync several times each evening but I don't even know how to recognise a loss of synch with this modem. I haven't been able to get much help from google.

It looks to me as though you connected the modem over 13 hours ago

Line Up Time 00:13:04:15

During that time you haven't lost sync

Line Up Count 1 [this figure increases every time you lose sync]

Further down I'm not technical enough to explain the errors but have you tried connecting into the Test socket where your BT line comes into the house? If the error rate improved this would indicate a problem with your house wiring [phone extensions etc]
