NoFUNCTIONCOMMENTS
0G3 protocol mode usedChange this bit to 1 only when the other end can
0: Standard and non-only communicate with machines that send T.30-
standardstandard frames only.
1: Standard only1: Disables NSF/NSS signals (these are used in
non-standard mode communication)
1-4Not usedDo not change the settings.
5Use of modem rate history for0: Communications using Quick/Speed Dials
transmission usingalways start with the highest modem rate.
Quick/Speed Dials1: The machine refers to the modem rate history
0: Disabled1: Enabledfor communications with the same machine when
determining the most suitable rate for the current
communication.
6AI short protocolRefer to Appendix B in the Group 3 Facsimile
(transmission and reception)Manual for details about AI Short Protocol.
0: Disabled1: Enabled
7Short preambleRefer to Appendix B in the Group 3 Facsimile
0: Disabled1: EnabledManual for details about Short Preamble.

0DIS detection number0: The machine will hang up if it receives the
(Echo countermeasure)same DIS frame twice.
0: 11: Before sending DCS, the machine will wait for
1: 2the second DIS which is caused by echo on the
line.
1Not usedDo not change the setting.
2Use of V.8 protocol0: V.8 protocol is disabled.
0: DisabledThe machine communicates in accordance with
1: Enabledthe T.30 protocol.
3ECM frame size1: ECM reception is disabled, which enlarges the
0: 256 bytesSAF memory.
1: 64 bytes
4CTC transmission conditionsWhen using ECM, the machine will choose a
0: Ricoh mode (PPR x 1)slower modem rate after receiving PPR once
1: ITU-T mode (PPR x 4)(Ricoh mode) or four times (ITU-T mode).
ITU-T: New acronym for the CCITT.
5Modem rate used for the next1: The machine's tx modem rate will fall back
page after receiving abefore sending the next page if a negative code is
negative code (RTN or PIN)received. This bit is ignored if ECM is being used.
0: No change1:
Fallback
6-7Not usedDo not change the setting.
