Q1) When to use any of above mentioned ?
Q2) How to calculate value for CBR or VBR-RT ?
For e.g :
ID(config)#interface ATM6/0.777 point-to-point
ID(config-subif)# pvc att-per 1/777
ID(config-if-atm-vc)#vbr-r t ?
<1-44209> Peak Cell Rate(PCR) in Kbps
ID(config-if-atm-vc)#vbr-r t 8000 ?
<1-8000> Average Cell Rate in Kbps
ID(config-if-atm-vc)#cbr ?
<1-44209> Peak Cell Rate in Kbps
ID(config-if-atm-vc)#cbr 44000 ?
If i have 2Mb PVC and 45Mb PVC ..please guide me how to calculate values ..

it has been a while (+10 years) since I worked with ATM circuits....
this has a reasonable description of the different classes http://en.wikipedia.org/wiki/Asynchronous_Transfer_Mode
are you provisioning the circuits as a provider or subscriber?
some more context would be useful

I want to understand QoS part on ATM interface like CBR,VBR-RT and VBR-NRT
possible scenarios when to use CBR,VBR-RT and VBR-NRT.
and how to calculate values to specified for 2mb,10mb ,45Mb circuits .
