COMMENTS
If training with a particular remote terminal always
takes too long, the initial modem rate may be too
high. Reduce the initial Tx modem rate using these
bits.
For the settings 14.4 or kbps slower, Switch 04 bit 4
must be changed to 0.
Note: Do not use settings other than listed on the
left.
If the setting is "Disabled", the bit switch setting is
used.
Do not change the settings.
Refer to Appendix B in the Group 3 Facsimile
Manual for details about AI Short Protocol.
If the setting is "Disabled", the bit switch setting is
used.
Do not change the settings.
