Thought I would provide an update to my 'ADSL life' in case it adds any value...
As I've mentioned before, I'm on a rural and fairly noisy line and have had a few issues along the way
The link in my signature contains details of my connection which I have tried to make the most of - filtered faceplate, router changes etc.
I've noticed over the last few weeks my error counts have been much improved.
FECs used to be in the 100,000's or 1millions for a day with HEC/CRCs in the 1000-10,000 range, but lately FECs have been in the 10,000's with some days worse and the HEC/CRCs sometimes staying in the 100's.
In the past as I've improved things at my end I've had to ask for my Target SNR to be manually reduced to improve my sync. This has been done in steps from 15db (set last summer during storms) to 12db and then at the end of March to 9db.
I was reasonably happy with this Target SNR (9db) with an attenuation of 50/51 and a sync of around 4800 - much better than ALL my near neighbours!
But today I've found that my Target SNR seems to have been automatically reduced to the default 6db - increasing my sync to 5504
Now whether my line is going to be able to support this only time will tell! My SNR used to drop from 9db to around 5.5/6db in the evenings - so I won't be too surprised if I drop my connection with my new Target.
I guess I've got to have some faith in BT's systems (
) and they know what they are doing. I won't be happy if my stable line suffers with this change...
People often ask questions about the 'rules' of having a Target SNR reduced (which is somewhat 'blackmagic') - so at least this shows a few things:
My router is turned off each night and back on in the morning - showing that you don't have to maintain a continuous sync. My sync's rise and fall by a few 100k.
So in my case it looks like the improvement in my error count has triggered the reduction.
Obviously I'll
