V.8 in Manual Reception
This machine starts the V.8 procedure in order to allow V.34 communication in
manual reception, though some other fax machines do not.
Refer to “V.8/V.34 Training Manual – section 3.1” for detailed procedures.
Shift-down Conditions
One-step Shift-Down from the Receiving Terminal
The diagram shows the protocol used by this model acting as the receiving
terminal.
If the machine has sent two PPRs for one ECM block, it will request the sending
terminal to make a one-step shift-down in the next control channel.
N eor: Number of frame re-transmissions remaining until the Tx terminal sends
DCN to terminate the communication. This is fixed at “9”, and is not
adjustable.
