This table defines the MEF BW profile attributes. The profile can be defined either directly to an entity i.e. UNI or EVC or per EVC.CoS as follows: UNI When the BW profile is applied to a UNI, the ' CoSProfileIndex' attribute's value must be set to 'none'. EVC When the BW profile is applied to an EVC, the ' nCoSProfileIndex' attribute's value must be set to 'none'. EVC.CoS When the BW profile is applied to an EVC and CoS, the ' CoSProfileIndex' attribute's value must be set to the correct CoS ID. A bandwidth profile outlines the service guarantees that the SP will provide by defining traffic types and amounts of each traffic type that subscribers can send into the SP's network.
