The provider aborts count is a part of the general performance measures gathered as a part of the performance statistics. It provides a count of the number of Provider Aborts experienced as a percentage of the CPDLC sessions conducted.
FANs does not have the concept of a Provider Abort but the 'FANS1/A to ATN Interop' document (ED154) defines a set of FANS conditions that are to be considered as a Provider Abort by an ATN ground system. These conditions are as follows:
- The transmission of an uplink error message UM159 with errorInformation equal to 'invalid data', 'insufficientdata', or 'commanded termination'
- The reception of a downlink error message DM62 with errorInformation equal to 'invalid data' or 'insufficientdata'
