Line Attenuation

[old Bill]

I was just wondering having tried various routers my line attenuation changes from router to router. Can anyone tell me why the diffrent routers can change the stats ? If you had a choice is it better to have a high line attenuation or a low one. Eg one router I tried gave me a figure of 46 and a diffrent one gave me 50. Which is the better figure ?

Hard to say, I've just switched ISPs and noted a small difference, yet its the same router on the same line to the same exchange. That should in theory read the same figures and variations, but in practice it does not.

Total mystery that is. Does not even make any sense that reading up on it can reveal.

Basically, Bill, the lower the attenuation the better. However, different routers may give different figures due to the way they're calibrated (a bit like different Sky boxes will give different signal readings from the same LNB), or to minor changes with the line (at migration time), or to the way they interact with the DSLAM.

I'm moving this thread to IDNet Help, btw.
