The USR 9105 ADSL statistics page reports

                      Downstream Upstream

Attainable rate (Kbps) 3808 928
Rate (Kbps) 3520 832

These look like negotiated figures and don't fluctuate, at
least while I have been looking at them. Are they the
"line speeds"? I don't know how to tell how long between
retrains.

I suppose the Nokia M1122 also had a log of such figures but
it is not now connected.

For the user's point of view, though, I would have thought the
achieved values with the Telecom test site were more important.

On a different topic:
the USR can produce a log of probes from the Internet. There
seems to be one every few seconds. Typical ports probed are
16708, 445, 139, 135.
