• LLC Encapsulation
Logical Link Control for Bridged Protocols. You can choose this encapsulation
type for PVCs. You cannot use this encapsulation type for SVCs.

desirable when it is not feasible for a larger number of VCs to be supported,
due to ATM device capacity limitations or other outside factors.

neither configured by hand nor set up dynamically.
