After any Configuration of CarSelCarrierTable, the CarSelCarrierTableSynchronization is set to TRUE. This means the Carrier Select application will be notified that new configuration has been made and it starts reading the new data in to its cache table. The Carrier Select application sets the CarSelCarrierTableSynchronization FALSE when it is ready. When CarSelCarrierTableSynchronization is TRUE no new configuration can be made in CarSelCarrierTable until the flag is set to FALSE again.
