what is Line Coding(Trellis): On Off mean?
I'm not sure, but since I posted this, CS have responded to my ticket and kicked off another SNR reset that actually seems to have gone through this time, resulting in these stats (and trellis back on for both):
Downstream / Upstream
Line Coding(Trellis): On On
SNR Margin (0.1 dB): 29 56
Attenuation (0.1 dB): 100 58
Output Power (0.1 dBm): 210 122
Attainable Rate (Kbps): 22252 22637
BTW speed test:
Download speed achieved during the test was - 12.91 Mbps
For your connection, the acceptable range of speeds is 4 Mbps-21 Mbps.
IP Profile for your line is - 17.58 Mbps
I'm hoping this is the sort of thing that'l now hopefully just fix itself providing I don't get a bunch of dropouts?
