This read-only value reports the current Data Rate Control (DRC) value the Access Terminal is requesting from the network over the DRC channel in EV-DO. A consistently low DRC value indicates the network is only willing to grant the modem a low data rate, often correlating with poor signal conditions, so an admin can use this alongside RSSI/Ec/Io to understand achievable EV-DO throughput. For example, seeing a low DRC value paired with weak Ec/Io readings during a slow-throughput complaint would confirm the modem is being throttled by the network due to marginal signal quality rather than a configuration issue.
