Introduction
Appendix B outlines the steps required to configure the
Si2400 for modem operation under typical examples.
The ISOmodem has been designed to be both easy to
use and flexible. The Si2400 has many features and
modes, which add to the complexity of the device, but
are not required for a typical modem configuration. The
goal of this appendix is to help the user to quickly make
a modem connection and begin evaluation of the
Si2400 under various operational examples.
Example 1: V.22bis in FCC countries
1. Power on reset
2. Set Host UART to 2400 bps
3. ATS07=06 set for QAM 2400 bps
4. ATDT18005551212<CR>
5. Next byte after “c” or “d” is modem data!
Example 2: V.22 in CTR21 countries
1. Power on reset
2. Set Host UART to 2400 bps with CTS flow control
3. ATS07=02 (set for DPSK 1200 bps)
4. ATSF5=1C (set DAA for CTR21)
5. ATSF7=18 (set DAA for CTR21)
6. ATDT18005551212<CR>
7. Next byte after “c” is modem data!
Example 3: Bell 103 in Australia
1. Power on reset
2. Set Host UART to 2400 bps with CTS flow control
3. ATS07=01 (set for FSK 300 bps)
4. ATSF5=38 (set DAA for Australia)
5. ATDT18005551212<CR>

Parallel Phone Detect
1. Power on reset
2. Set Host UART to 2400 bps with CTS flow control
3. ATS07=01 (set for FSK 300 bps)
4. ATSF5=38 (set DAA for Australia)
5. ATSE2=C0 (enable ALERT pin)
6. ATDT18005551212<CR>
7. Next byte after “c” is modem data!
Example 5: Bell 212A in South Korea with
Japanese caller ID
1. Power on reset
2. Set Host UART to 2400 bps with CTS flow control
3. ATS07=00 (set for DPSK 1200 bps)
4. ATSF5=06(set DAA for South Korea)
5. ATS13=80 (set caller ID to Japanese format)
6. ATDT18005551212<CR>
7. Next byte after “c” is modem data!
Si2400 may echo the following:
t – tone dial detected
, – dialing complete
r – ringback
b – busy tone
N – No carrier
c – connect
Si2400 may echo the following:
t – tone dial detected
, – dialing complete
r – ringback
b – busy tone
N – No carrier
c – connect
When caller ID data is detected, Si2400 will echo “f”
indicating the line reversal, “m” indicating the mark, and
then caller ID data will follow.
