I think you are confusing the issues here. The adaptation layer you use is
independant of the QoS. You can get CBR, VBR, ABR or UBR with AAL5. This
is somehting you have to negotiate with your network before you setup the
VC. This is typically set by ioctl() calls in most of the Unix API's that
I have seen.
