Is this possible?

[ziglet]

Is it possible for me to phone telkom and have them test the highest sync rate possible for my line? Cause i dont want to upgrade to 1mbit and find out my line will max out at 1mbit...

They probably can but probably wont if you ask them.

Input the variables it asks for (you'll find them on your router's interface), and that should give you a vague idea.
