3
ECM frame size
0: 256 bytes
1: 64 bytes
Keep this bit at "0" in most cases.
4
CTC transmission conditions
0: After one PPR signal received
1: After four PPR signals received
(ITU-T standard)
0: When using ECM in non-standard (NSF/NSS) mode,
the machine sends a CTC to drop back the modem rate
after receiving a PPR, if the following condition is met in
communications at 14.4, 12.0, 9.6, and 7.2 kbps.
Ntransmit = Number of transmitted frames
Nresend = Number of frames to be retransmitted
1: When using ECM, the machine sends a CTC to drop
back the modem rate after receiving four PPRs.
PPR, CTC: These are ECM protocol signals.
This bit is not effective in V.34 communications.
5
Modem rate used for the next page
after receiving a negative code
(RTN or PIN)
0: No change 1: Fallback
1: The machine's tx modem rate will fall back before
sending the next page if a negative code is received.
This bit is ignored if ECM is being used.

7
Select detection of reverse polarity
in ringing
0: Off
1: On
This switch is used to prevent reverse polarity in ringing
on the phone line (applied to PSTN-G3 ringing). Do not
change this setting
0: No detection
1: Detection (Japan and Korea only)
G3-2 Switch 04 (SP No. 1-106-005)
No
Function
Comments
0-3 Training error detection threshold
0 - F (Hex); 0 - 15 bits
If the number of error bits in the received TCF is below
this threshold, the machine informs the sender that
training has succeeded.
