@burakkucat, @NewtronStar,

my disconnections seem to be preceded by lots of FEC's & then CRC's, could these errors be caused by rain?

[NewtronStar]

Once you have the RPi up and running you can use uk weather radar and see if the rain and DSL stats have something in common.

@NewtronStar,

I can see if it's raining out my window lol

Strange HLog & Quite Line before I go to bed, attached

[roseway]

Do remember that HLog and QLN are only snapshots of conditions at the time of the last resync. They aren't updated in real time.

[William Grimsley]

True, though with the state of his line, it's nearly like real time!

At least G.INP has come on, you can see how well the line is performing now!

[MaximusPrime]

@roseway, @William Grimsley,

cheers, yeah with all the re connections HLog seemed to be in real time

10.7Mb downstream today, no rain, supposedly going to rain at the weekend so I'll see if it's the cause then

[renluop]

Excuse me for butting in with what may be a silly question.

Are QLN and Hlog in anyway technically related?

[MaximusPrime]

@renluop,

from my understanding but I might be wrong:

- HLog shows the Attenuation per tone
- Quite Line shows how much noise there is per tone

The lower the values the poorer the quality of the tones

The 2 graphs are probably combined with other info to give your tone graph...

[roseway]

@renluop: QLN and HLog are quite different things. The only connection is that both are measured immediately before sync.

QLN (Quiet Line Noise) is a measure of the background noise on the line over the frequency range in the absence of any DSL activity.

HLog (Logarithmic Channel Characteristics Function) is effectively the gain of the line over the frequency range, in logarithmic units (dB). This is the inverse of attenuation.

The 2 graphs are probably combined with other info to give your tone graph...

No, that's not the case. All the other reported values are determined in real time.

[MaximusPrime]

@roseway,

are the HLog & QLN values used by the LCP (Link Connection Protocol) when establishing connections? Resulting in your connection rate?

Was I right in saying the lower the values of these graphs results in lower quality of the tones?

[roseway]

LCP is concerned with authenticating the internet connection after sync. So it's not related to the connection speed.

I'm no expert on HLog and QLN, so I'm afraid I can't help with your other questions.

[MaximusPrime]

Tiniest bit of rain & I've had disconnections, could there be a problem with the new line that was installed?

[burakkucat]

There clearly is a circuit fault but the problem is identifying "what and where". Fifteen resynchronisation events in the last 24 hours. 

If you are located in the Surrey hills, to the south east of Guildford, I am sure that Walter would be willing to trundle the wheelbarrow around to your location and initiate a comprehensive infrastructure review & circuit monitoring session.

[William Grimsley]

Eeek, look at the line now!

[MaximusPrime]

Yeah I'm disappointed, been working on getting reliable broadband for a year & a half now since my ADSL started cutting out

I finally get a 10Mb line & it cuts out on the slightest bit of rain 

Fix 1 problem, gets another
