Fw: Further to my ADSL Faceplate Question

[Gareth Cook <g@xxxxxxxxxx>]

Or a cheaper method is to remove/cut wire 3 (the ringer). You don't
need=20
it at all. That's all the BT i-plate does.

I meant from Traceys own transmitter :o)
Your theory is possibly true - also don't forget all those CFL lamps,
LCD=20
TVs and street lights that get switched on at nighttime, they're
emitting=20
and adding to the problem too.

If you haven't got an adsl master socket have you tried using a BT=20
accelerator - aka an i-plate?  You can get them for approx =A38 and can
hel=
p=20
a lot with these sorts of issues.

Also, I've noticed our adsl SNR improves in really cold weather - I wonder=
=20
if it's due to lower thermal noise in the copper wire - or maybe it's=20
coincidence.

That's what Im seeing. Between sunset and sunrise, I see a change in SNR=
=20
on
ADSL, and slower sync speed, from 6Mb/s down to 4.5-5Mb/s. I only see=20
this
change when its dark.

My theory is this is due to the ionosphere becoming more effective and
increasing the 'skywave'

The overhead BT lines are acting as antenna, increasing the noise on the
line.

I would expect anyone with overhead BT lines would suffer from same.
