0x00

0x09

Send RFS to host after incoming continuity result is received.
When setting this byte to 0x01, the host should not try to send any call processing API on the circuit where incoming Continuity Check is being performed, until continuity check results are received in the form of PPL Event Indication.

0x00 = Send RFS after Continuity has been performed


0x01 = Send RFS before Continuity has been performed
