I started off by configuring the 64-bit version to my own preferences (image
rsux-08.png, below) and set it executing just before 2000 hours BST, yesterday.
Leaving it alone in a work-space of its own, I continued to use my laptop normally -- other than logging out. When it became time to retire to that warm and sleepy spot, I ensured that the laptop was running from the mains electricity supply and closed the lid.
Reviewing the
Connection speed graph (image
rsux-09.png, below), the first thing that is apparent is the (boring) plotted straight lines (very good)! Note that I managed to obtain the screen-scrape whilst the utility was displaying the confidence-boosting "
Sampling" message in the top right-hand corner. Looking at the bottom of that image, we see --
Attn. Down: 50.5dB Attn. Up: 28.5dB Downstream power: 0.0dBm Interleave Depth: 32
My personal preference is to have a space between the numerical value and its corresponding unit. For example, "
Attn. Up: 28.5 dB". Is there a convention that covers such detail, please?
Moving on to the
SNR margin graph (image
rsux-10.png, below),
yuck!
(Not at
Eric's excellent work but my line's behaviour, last night.) Again, as above, I would prefer a space between the numerical value and its corresponding unit.

With regards to my line, it is a
TalkTalk fully LLU'd service. The MSAN has an
Infineon chipset and is configured with the DLM disabled, interleaving on and a target SNRM of 6 dB.
As the
Huawei HG612 uses a
Broadcom chipset (
BCM6368), I have tweaked the DS target SNRM to 4 dB by means of the technique documented in the
Kitz wiki.
By consideration of my yucky
SNR margin graph, there is clearly some (new) form of RFI being generated at certain times of the day. It's time to blow the surface dust off my
Icom IC-R5 and start "sniffing" the radio spectrum at 306 kHz and 612 kHz.
As for the
HG612's ability to "hang on" in the presence of noise, I have to say that it is very good. I have been happily using my broadband connection when the SNRM has dropped at low as
-1.9 dB! And that was not momentary, it was for about 20 minutes. Finally when the SNRM hit
-2.0 dB the
HG612 finally "let go" and re-negotiated sync with the MSAN.
