The interesting thing to note is that the
2700HGV first tries at
ADSL2+ mode but quickly settles on
ADSL2, due to an inconsistent signal with the former.
I see exactly the same with my own "not so long" line. (See Screenshot-1 & -2, attached below.)
DSL Down Up
Current Rate: 3873 kbs 872 kbs
Max Rate: 3873 kbs 872 kbs
Current Connection:
Current Noise Margin: 10.0 dB 12.1 dB
Current Attenuation: 46.4 dB 27.8 dB
Current Output Power: 18.9 dB 12.4 dB
Looking at my
SNRM graph, I see I have had an unusually "noisy" past 24 hours.
I wonder what external event has caused that . . . surely not fireworks!
This is an appropriate moment to acknowledge the help I have received from
Bald_Eagle1 with guidance in the use of
gnuplot to create the graphs.
