Hi Guys,
One of our clients had a poor ADSL connection and the ISP checked on it and advised us that the ADSL is currently not on ADSL2+ ( which I could verify from the router ) and they changed the connection profile from their end.
After the change, when I do the "show controllers VDSL 0" command , it does not show me the uplink parameters ( as highlighted below) although the site still has Internet access.
Is this a bug ? or can someone explain me what is going on here ?
Appreciate your help.

hi,
did you try to re-train your ADSL link and got the same result? try to shut/no shut ATM.
you might also want to consider the 'Speed' parameter instead.

Hi johnlloyd_13,
Sorry for the late reply, Yes I reloaded the router ( I can't shut/no Shut ATM because I'm doing everything remotely, I think reloading the router would have the same effect on the ATM interface ?? ).
The Interesting thing is that, I got one of the users in the site to do a speedtest.net test from behind the router and he is getting around 5Mbps/0.5Mbps dowb/up speeds ( but varies with time ) which doesn't make sense.
Please have a look at the "show int dial 1" output, ATM and Dialer configs for this. Please let me know if you can see anything obvious.

Hi there,
Configure the vdsl controller and try again after rebooting the router:
conf t
Controller vdsl 0
Operating-mode ! Here you choose the mode that better works.. Not always auto does it
End
Wr
!
however, in my opinion there are issues with the sp because the attainable rate (upstream) is 0. That is not a good value at all.
The dB are not matching amazing values either.
Hope this helps
