This read-create value, in octets per hour, configures the minimum acceptable GPRS QoS mean data rate the device will accept as its sustained throughput floor. An admin sets this to ensure the negotiated connection provides at least enough average bandwidth for the site's ongoing traffic, rejecting network offers that fall below this sustained-rate floor. For example, a branch relying on cellular as primary WAN would set a higher minimum mean rate here than a site using it only for occasional backup connectivity.
