Forced 2400 symbol rate
when probing SNR is adverse
Usage/Comments
If the error frame often occurs because of the
symbol rate is too high, setting this switch to
"1" mask that symbol rate and keep down the
occurrence of error frame.
See above (switch 5 to 2).
Usage/Comments
SNR means that Signal Noise Ratio.
If the SNR is less than the threshold you set,
the modem overrides the bandwidth evaluation
algorithm and forces the symbol rate to2400 baud.
