Automatic fallback will occur according to the following se-
quence by FTT, RTN or PPR.
When the last trial fails, the transmitting station sends out a
DCN signal to the remote station for disconnection.
Note 1: Continuous PPRs for the same partial page within
each fallback rank.
1) ITU-T Rec. T.30
2) Oki Data special protocol
High-speed protocol
The T.30 protocol signal from the transmitting station is
sent at message transmission speed instead of 300 bps.
(This function is disable when the H/Modem rate is set to
9.6 kbit/s by TS No.13)
