Si2456/Si2433/Si2414
A
Introduction
Steps required to configure the Si2456/33/14 for modem
operation under typical examples are outlined below.
The ISOmodem has been designed to be easy to use
and flexible. The Si2456/33/14 has many features and
modes that add to the complexity of the device but are
not required for a typical modem configuration. The
following examples help the user quickly make a
modem connection and begin evaluation of the Si2456/
33/14 under various operational scenarios.
Example 1: V.90 in FCC Countries
1. Power on reset.
2. Set host UART to 19.2 kbps.
3. AT\T12 - set ISOmodem UART to 115.2 kbps.
4. Set host UART to 115.2 kbps.
5. ATDT15128675309<CR>
6. Next byte after “CONNECT 56000" is modem data!
Example 2: 33600 bps in Norway
1. Power on reset.
2. Set host UART to 19.2 kbps.
3. AT\T12 - set ISOmodem UART to 115.2 kbps.
4. Set host UART to 115.2 kbps.
5. AT&H2 - limit Si2456 to V.34.
6. AT:U2C,00B0,0080 -Busy tone cadence set for Norway.
7. AT:U67,000C,0010,0004:U4D,0001 - DAA PTT settings for
8. ATDT15128675309<CR>
9. Next byte after “CONNECT 33600" is modem data!
Example 3: V.22 in Australia with Parallel
Phone Detection
1. Power on reset.
2. Set host UART to 19.2 kbps.
3. AT&H7 - limit Si2456/33/14 to V.22 only.
4. AT:U67,0064 - DAA PTT settings for Australia.
5. AT:U70,2400 - Enable off-hook intrusion interrupt.
6. AT:R79 - Check for phone in-use before dial.
