hi can anybody decipher these line stats
That command doesn't actually display attenuation.
You would need xdslcmd info --pbParams to see that.
It may be helpful if you posted those details for us to have a look at.
Your SNR values suggest a higher downstream speed could be achieved, but not much more upstream.
Unusually, your upstream Interleaving is ON (at a low level) & Downstream is OFF.
It is usually the other way round.
If your stats have always looked like this, it could suggest you are a long way from the cabinet, or you have a physical repairable problem somewhere.
Any idea of distance from the cabinet that you are actually connected to?
Does the modem resync regularly of its own accord?
This again would suggest physical problems.
