Hi all,
I was wondering if you could help me answer a query please
With a Huawei HG533, our upstream line attenuation is reported as 31.5 dB and our downstream is reported as 56 dB - we're about 2 miles from the exchange and plotting the line route plops us in the 3.5 km line length, so the line attenuation is about right. Also, as I understand it, a rough rule of thumb is that upstream attenuation is about half of downstream, so the figures look okay.
We switched to using a Netgear DG834G v3, since, despite being 7 years old, it just guffaws at attempts to knock it off the line (whereas the HG533 would run a mile in the other direction), and the downstream line attenuation, using the same ADSL mode, is reporting as 50 dB, which is likely due to the different way the Netgear reports attenuation. The upstream attenuation is now at 15 dB however, quite a difference from the 31.5 dB reported by the HG533!
Could it be the upstream attenuation is much lower just due to the way the Netgear router is calculating the upstream frequencies compared to the HG 533? Our line is operating stably at 6 dB SNR, no noise and no disruptions, and we get around 6 Mbps which is good for our line!
