FTTC Output Power Levels v Sync Speed
Hi All,
I have recently noticed from my HG612 modem's GUI that my DS Output Power levels fluctuate a little, quite often between GUI screen refreshes, so I have graphed power levels to get a visual idea of what it looks like.
The first graph is from a 18Mb Sync speed FTTC connection.
The second graph is from my 30Mb Sync speed FTTC connection
The third graph is from a 40Mb Sync speed connection
Just concentrating on DS Output Power levels for now, the difference in pure visual appearance is clear.
My own connection has been rather unstable over the last 7 months or so, eventually having a DLM reset 10th March, which initially provided a 35Mb sync speed for the first time since July 2011.
I first thought that stability had also improved, but following a number of "on the fly" resyncs at lower speeds, it is back down to 30Mb Sync speed, with Attainable rates around 33Mb to 36Mb, depending upon the time of day.
The 18Mb connection is stable, but around 1600m from the cabinet.
The 40Mb connection is also stable & around 500m from the cabinet.
My own 30Mb connection does not appear quite so stable & the 4 day graph above shows fluctuations in DS Output Power levels, whereas the other 2 connections show very steady Output Power levels.
I also notice the differences in DS Output Power levels for all 3 connections is not massive, despite the large differences in sync speeds.
The whole range is only between 11 dBmV & 13.7 dBmV.
I have seen other Output Power graphs from other users with varying speed connections & they also look steady.
The Windows Ongoing data harvesting script already stores any changes to Output Power levels, but the released graphing scripts do not plot the graphs (yet).
If anyone on the 80/20 trial would like to send me a copy of their ongoing modem_stats.log, could you please contact me via PM for an email address, or if you already have my email address, could you please forward a copy to me?
Alternatively, could you please upload the log file somewhere & post a link to where I could download it?
I will provide the graphs by return email, or post them here.
Does anyone know if the Output Power levels come from the actual sync speeds, or are sync speeds dictated by Otput Power levels?
Does anyone know if fluctuating power levels are a symptom or a cause of an unstable connection, or is it a "normal" phenomenon?
Paul.

its the BT HH3 some say its great others say its bad , the Asus is a great router
Unfortunately BT isn't my service provider, so I can't really use the HH3. After reading a lot of reviews I went with the Asus.
a) it will revert back, and it runs until nearly the end of April now. A month of free double speed, why not.
b) it's a profile change, it will happen practically instantly in the middle of the night.
c) Mine likes watching the speedtest dial fly round to 65mbit
Has anyone in a mixed fttc/p area got fttp yet?
Supposedly we're meant to be able to get infinity here by the end of march yet i've seen no sign of fttp even though a bunch of cabs have popped up for others around here, the bt checker isn't very helpful.

The 6.4meg is a little off, I get 8-9 at the moment, so hoping the 56.5 is a little higher, but the 15.7 sounds good to me!
Also "Superfast Fibre Optic Broadband is planned for your line in April 2012" so that's confirmation 80/20 goes live in April
(not that the Openreach document wasn't already confirmation!).![[TW]Fox](/data/man-of-honor/2009.png){kind=avatar}
Anyone else having problems?
