That's all the 2640B will report.
To me there is nothing unusual about the data - it's always been like that!
The line seems to work exactly as expected with D/S download tests just below the IP setting (this is Plusnet with their wretched IP profile which is meant to mirror BTOR's less a bit)
[I recall when I was on 20CN the line ran at the full 8128Kbps sync limit with obviously as a result lots of spare D/S SNR margin I recall it was usually around 10dB]
I did briefly borrow a Dlink 2740B in probably 2012.
It does report additional data
Fortunately I made a note of the additional stuff (not that it means anything to me) and the extra data for the D/S was.
INP 1.1
PER 16.08
delay 7.68
OR 33.32
Sadly neither routers report the DSLAM manufacturer and I know of no one else locally who is interested in this sort of thing or prepared to look into it even if they do have a unit that 'might' report it.
Basically I'm one of the lucky one whose line just works as it should and pretty well always has.
I have had a couple of 'single line dis' faults which makes the sync drop to very low levels. BTOR have fixed fault and the broadband simply reverts to the as before data and sync levels.
When a thunderstorm passes nearby the CRC's go mad and the line effectively stops though it remains in sync and then continues as normal afterwards.
I did have one exchange located fault in probably 2011 which caused the target to be raised to 6. Once fault was cleared the DLM monitored the line for a couple of days I think at 6dB and then took action and just returned it back down to 3dB again and on we went as before.
Oh yes and the ping test to
www.bbc.co.uk this morning gives 30ms - again as normal and as it always has been.
