Automatic fallback will occur according to the following sequence
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:
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.
Note:
In high-speed protocol, 28.8 K-bps are not supported.
6 sec. /ITU-T No. 1 sample document
Note:
This is Phase C time at 3.85 line/mm and 14400 bps for 6
sec. in MMR code transmission.
