Both the PPP callback request and PPP callback accept will be placed on
the BRI interface. This does make sense as these are features of LCP and
not of NCP, LCP is generally associated with the BRI interface.
The PPP multilink is placed on the physical interface for incoming
calls, in the dialer profile for outgoing calls, and on both the
interface and dialer profile when incoming and outgoing calls are expected.

Yes, allthough I have allways done this, I am not absolutely sure why it
is required?
