Does it affect things when you use it?

Not really. But up until yesterday when I was starting to play online it looked much better look here for example from 3pm to 11pm online gaming http://www.thinkbroadband.com/ping/share/3e8e297c7dc... So how come idle connection look worst then being used ?? Mystery if you ask me

Mystery to me as well I'm afraid.

No problem, maybe someone will be able to explain it...

Hmmm.... I wonder what happened. Now it looks as it should :

Missed this originally, but I'll answer for posterity...

The line is working fine, and has quite low attenuation figures in the "--pbParams" output - slightly under half the values of my (old) 350-400m line.

If your line is 300m from the cabinet, then it is on thicker copper than 0.5mm; you are getting results akin to nearer 100m of standard copper (which I'd be able to confirm if BT got their finger out & installed fibre in our new home).

Those max speeds - 133/42 - are among the highest I've seen, though they are likely to decline as crosstalk affects things when takeup increases.

As for the "-4dBm"; it isn't a thing to be worried about. The negative number only means that you are transmitting at a lower power than some reference value; by itself it means nothing ... so long as you are getting your package speed (20Mbps) with 6dB SNRM or higher.

The likely reason for transmitting at a lower power is because of "upstream power backoff", where the DSLAM has ordered you to reduce power because you are so close. If your modem shouted louder, you'd be interfering with the signal on longer lines.

The discovery issue ... is a strange one. It seems that ECI cabinets get different boundaries to Huawei cabinets. It ought to be configurable, and ought to be easy to make it consistent ... but isn't. Perhaps the manufacturers' transceivers have some intrinsic limitations.

That is one reason. It is also possible to swamp the input stage of the DSLAM causing distortion and corruption. There is a fairly wide dynamic range however there will be a finite limit.

The same also happens on downstream too - I saw it on a few ADSL lines close to the exchange.

And about Discovery Phase (Initial) Band Plan. mine is :
US: (7,32) (871,1205) (1972,2782)
where everyone else seem to be(0,95) what does it mean in my case?

Those reporting (0,95) are using older modem firmware versions (pre-October 2013 updates).


These are the latest band plans from Huawei DSLAMs when using updated HG612 firmware versions:-

Discovery Phase (Initial) Band Plan
US: (7,32) (871,1205) (1972,2782)
DS: (33,859) (1216,1961) (2793,3970)



These are the latest from ECI DSLAMs:-

Discovery Phase (Initial) Band Plan
US: (6,31) (882,1193) (1984,2770)
DS: (33,857) (1218,1959) (2795,4083)



So, we can see that you are connected to a Huawei DSLAM.

However, your DS band plan ends at tone 3959.

That could either be that your modem hasn't fully flashed with the latest firmware or that the DSLAM's firmware itself hasn't been updated.

I'm more inclined to think your modem's firmware is only partially updated.
