If the profiling is required between exchanges and primary points then it'll be common to both.
Which reinforces the position that someone is either telling porkies, or is being fed duff information.
The Entanet resellers have made it quite clear there will be many more profile steps, at much smaller increments than with ADSLmax, yet the link provided in this thread shows that not to be the case.
Someone's got it wrong (or BT have been moving goalposts again), it would be nice to get an opinion from Entanet (or one of their resellers) or A&A, because nobody else is likely to know for sure (other than BT - possibly

).
