This creatable/settable object configures the minimum acceptable maximum-uplink-bit-rate value for a profile's QoS negotiation, the floor below which the network's offered uplink ceiling should not fall. An admin sets this to prevent the network from negotiating an unacceptably low uplink ceiling for the profile, ensuring a baseline of upload capability regardless of what's requested. For example, an admin might request a high maximum uplink rate but set this minimum-acceptable value lower, defining the least amount of uplink capacity that would still make the connection usable.
