I've recently ordered DoBroadband3. The Telkom call-center tell me that my exchange only supports 512kbps, HOWEVER, they will do a conformance test to double-check. Now I've heard rumours of this before, and usually it ends well (ie. they are just covering their a55es, and it should support 4mbps) but I'd love to hear some real-life stories to put my mind at ease. 
I am in the New Germany area (031705xxxx).
