CBR? Required to reserve BW even if no CBR traffic?

I've been trying to research if a vendor is ATM Forum compliant (or has a 
good design).  They say that any unused CBR traffic is available for 
anybody else's use.  Looking at TM4.0, I only see that if a switch 
accepts a CBR connection then it must provide what was contracted for.  
I've also heard how inefficient CBR is because the bandwidth goes to 
waste.  If a vendor has CBR in the highest queue, then couldn't CBR 
traffic that was ramping up just start using that queue and still get his 
QoS satisfied?

Thanks.
