This object reports the current state of the TCP connection state machine used for sending accounting data to a collection device, explicitly set to unused(0) when the chassis is instead storing data on local disk. An admin using wire-based accounting collection watches this to confirm an actual open TCP session exists to the collector, since a value stuck at closed rather than open would explain accumulating CDRs (chasAccountCdrCount) with no data reaching the collection device. If chasAccountMethodInUse reports wire but this object shows closed(1), the admin knows the TCP session to the collection device has dropped and billing records are backing up locally instead of being delivered.
