I am thinking i have a bad line with the line attenuation so high, but would like other opinions before i lodge a fault.
Cable length is approx 700m from the node.
Maximum Line rate
10.61 Mbps 43.29 Mbps
10.61 Mbps 41.69 Mbps
38.08 MBytes 407.77 MBytes
6.3 dBm 14.5 dBm
9.2, 45.8,N/A dB 21.1, 57.3, 86.3 dB
6.5 dB 6.6 dB

Your speeds looks good for the distance - don't expect much more - but the attenuation looks bit higher (BTW, do you understand what the difference between the three numbers 21.1, 57.3, 86.3 dB is?)... Do you suffer drop outs?
I am about 700 Meters from Node and have almost the same attenuation. The Node is 200 Meters in a direct line but the Pillar I am connected to is in the opposite direction. Total cable distance is about 700 Meters.
I do not understand the difference between the three numbers, other then the higher the number means more noise on the line. I honestly thought with that number being so high i would have a lot of dropouts, but i have one drop out every 2-3 months.
Thanks for the reply ForensicsGuru.
The numbers represent the attenuation of the line. There are three because the attenuation varies with frequency. The figure on the left is for low frequencies, the middle figure is for mid frequencies and the figure on the right is for the higher frequencies.
The amount of attenuation reduces the level of the received signal so it is lower compared to background noise. As the cable length increases the attenuation increases, but because attenuation at the higher frequency is greater the higher frequencies can not be used for data transmission and also frequencies can not transmit as much data resulting in the speed decreasing as the cable distance increases.
Faulty terminations, or equipment causes dropouts.
