If the GSME is operating in prepayment mode it shall record the Prepayment Daily Read Log data items at midnight UTC. In ZSE terms, the GSME shall take a prepayment snapshot of the relevant items. The format and data of the prepayment snapshot taken is defined in ZSE.
The GSME shall use the snapshot cause ‘General’ (0x0001) for the prepayment snapshot taken.
The GSME shall push the prepayment snapshot to the GPF using the Publish Prepay Snapshot command.
The GPF shall populate the relevant attributes upon receipt of the Publish Prepay Snapshot command, providing the command is received between midnight (UTC) and the next scheduled wake of the GSME.
The GPF shall store the data contained in the Publish Prepay Snapshot command in the GPF copy of the GSME Prepayment Daily Read Log.
In the event of a communications outage, the GPF shall retrieve missing prepayment snapshots using the GetPrepaySnapshot command (and GetPrepaySnapshot notification flag) with the UTC start time field populated based on the last received prepayment snapshot timestamp, if one has been received.
