1) on the first telnet screen you should be able to type sysutil xdslmon (this may be more useful to OP since it shows estimated attainable upload rate too)
2) type system shell vdsl enter password: superikanos (turns out to use the default chipset pw) hit 11 to Request Extended Port Status ctrl^c to exit
PS if anyone from Bell's management reads this. Next time you spend millions for a custom product you should request these self-diagnostics are included in the web GUI instead of making the little guy jump through hoops to get them. I saw other ISPs using Sagem with much more elaborate options in the GUI. It's a bit ridiculous why you would exclude something so simple with no harm.
