This read-create Unsigned32 object specifies the profile's APN-AMBR, the aggregate maximum bit rate shared across all non-GBR bearers and all PDN connections using the same APN, a value that is part of the subscription but may be overridden by the network's PCRF. An administrator configures this to set an expected bandwidth ceiling for best-effort traffic on that APN. For example, a carrier-imposed data cap on a machine-to-machine APN would be reflected by setting this object to match the subscribed rate.
