PRELIMINARY
This option uses the ITU-T modulation standards for
all telephone line data rates, unless S-register S37 is 2 .
These rates include V.22 for the 1200 bps telephone
line data rate, and V.21 for the 300-bps telephone line
data rate.
When S-register S37 is 1 , V.23 is adopted when the
originating modem is transmitting at 75 bps and
receiving at 1200 bps. The answering modem trans-
mits data at 1200 bps and receives data at 75 bps.
When S-register S37 is 2 , Bell 202 is adopted when
the originating modem is transmitting at 150 bps and
receiving at 1200 bps. The answering modem trans-
mits data at 1200 bps and receives data at 150 bps.
This option uses the Bell modulation standards for
1200-bps and 300-bps telephone line data rates, unless
S-register S37 is 1 . Bell 212A at 1200 bps is adopted
instead of V.22. This value is the default value for
North America.
Bell 102 is used when a 300-bps telephone line data
rate is required.
If neither the 1200-bps nor 300-bps telephone line data
rate are required, a setting of B1 is ignored and the
modem functions as if B0 is set.
