It could, I suppose... but it's not too likely.  I presume you mean
that they terminate Full- and Frac-T services on different routers at
their end?  Maybe, but who cares?  I've done this sort of thing on Frame
circuits, and it runs just the way he expected: you put two people on
the circuit on the phone, they both flip the same switched at the same
time, and your throughput changes.  If they'll _upgrade_ you from Frac-
to Full- that way, why in hell won't they downgrade you?

The finances should be immaterial to the engineering, in this case.
