Certain rules for bandwidth-on-demand apply, depending on
whether BACP is negotiated. If BACP is not negotiated, the origina-
tor of the call will perform the dynamic bandwidth adjustments on
its own. If BACP is negotiated, the decisions are made on either side
but the call is always from the originator.
PPP/Compression

when set to None.
